I guess it can't hurt to try... Very annoyed by the fact that intrinsic functions which are overloaded don't behave like regular overloaded functions, in that trying to add an additional overload will hide the intrinsic function instead. https://quality.embarcadero.com/browse/RSP-12795

Hi! I am a Delphi developer from Hungary. I'm using it since Turbo Pascal 7.0 or so. Currently I'm using the latest Delphi Seattle, with a lot of TMS components, too.

hola como estan?? tengo una pregunta, los reportes con QuickReport como se imprimen desde el cliente??

I have an article may be useful  http://www.youtube.com/watch?v=XzuzG8elfLY

An old article, but still accurate on most of its content. Performance is not an easy task, unless you follow some simples rules... And know a little bit what is happening behind the scene. http://blog.synopse.info/post/2011/05/20/How-to-write-fast-multi-thread-Delphi-applications

Hello guys, I built a FMX Windows app from scratch, I have never seen a Delphi app running on Windows 10, but something got wrong and it is flickering a lot, when I interact with a control, the background get black and normal, normal and black and so on, at the same time other controls are weird rendered :( My Windows 10 is the 10.10.10240 build Thanks :D

Pascal Expert from Peganza has been released (the competitor to Roman Yankovsky's FixInsight) Information can be found here :  http://www.peganza.com/products_pex.html , with documentation found here :  http://www.peganza.com/pexhelp/index.html http://www.peganza.com/products_pex.html

Hi group Need some help in convrert C+ code, namely char** e.g in a function call to a dll to get data:  char **return_data, int *return_data_len  return_data: Pointer to a pointer to the memory location of a char array containing the data returned from the datalogger I am suspecting its a pointer to a pointer of array (pansichar) I have googled...found like to use ^pansichar ? Thanks for input on how to use this (how to code in the header file for using the dll and how to handle the data passed to the program calling the dll file ( I suspect its an array where you need to allocate size that is set by the returned data length sort of thing) thanks!

I know this might as so often turn into a "language X is better" or "I've been using Delphi before you were even born I like it as it is" argument but I will risk it anyway (but since I got the mighty power of comment deletion for this post I will use it to remove all the unconstructive flaming - deal with it ;p). Let's talk about something that is called "ceremony vs essence" (see  http://bryanpendleton.blogspot.de/2010/02/ceremony-vs-essence.html ). Don't get me wrong: I like the Delphi language (why else would I waste a lot of my precious time writing open source in it...) but I feel it's way too much ceremony. When I have to exactly explain how something should be done instead of just writing what I want to achieve when I don't need to and typing long expressions and boilerplate code I feel the language forces way too much ceremony. And no, it's not just about the typing but also about reading more code than would be necessary....

Confession: My name is Lars Fosdal, and I am a writer of frameworks. It's just so hard not to do it!. I really dislike cut & paste code or having to rewrite the same code with just different types!  Generics are really addictive, and I fear I have become a user.

Hello! So... I got a bit of friendly tease to do for Julian Bucknall :) Julian, I am sure you already know this, but DevExpress isn't allowed to "cheat" :) If you sell an RTF control, it MUST contain code to print the document :D You can't ship it without that! At the very least, provide a way in code to do it - and use it in the demos :D I looked into the Demos and the action for printing is invisible!!! DevExpress isn't allowed that luxury, we're spoiled! :D A

WTF ?! this application just stop after the splashscreen under lolipop on a SONY tablet Z2 Android 5.1.1, and Samsung S5 Android 5.0, it works on a Samsung Tab 2 Android 4.1.2...the project compiled with Seattle works fine in debug mode but stop also in release mode ?!

How can I remove this dependency to classes.dex on an Android project started under XE7, then XE8 and now Seattle ? I can uncheck them, but can't delete them :/

Test case management tools What tools do you use for creating and managing tests and executing them? I'm not thinking of DUnit/X - but manual, hands on tests, although integrating with automated testing would be a bonus.

#10Seattle I am running Seattle Ent.  on Windows 10 Pro.  I have an Intel Core i7 and 16 GB Ram.  The IDE "blinks" about every minute.  All the toolbar icons go away for about 4 seconds and the IDE is totally non-responsive. It is more than annoying. Is anyone else experiencing this?

I've actually run across a situation where Error Insight and Find Declaration can find the identifier in question, but the compiler cannot.  Fun, fun!

Delphi 2010 - Seattle - TFile.GetLastWriteTimeUtc returns wrong (-1 hour), for a file timestamp set with TFile.SetLastWriteTimeUtc. Looks like caused by daylight savings offset. Sample below: var   fileName: String;   fileTimeStamp: TDateTime; begin   fileName := 'D:\testdate.txt';   //create the file   if not TFile.Exists(fileName) then     TFile.WriteAllText(fileName, ' ');   fileTimeStamp := EncodeDateTime(2015, 8, 22, 14, 26, 22, 0);   ShowMessage('Set ' + DateTimeToStr(fileTimeStamp)); //shows 2015-08-22 14:26:22, correct   TFile.SetLastWriteTimeUtc(fileName, fileTimeStamp);   ShowMessage('Get ' + DateTimeToStr(TFile.GetLastWriteTimeUtc(fileName))); //shows 2015-08-22 13:26:22, wrong -1 hour end;

To all the "Delphi codegen is horrible" folks out there - has any of you ever tried Delphi2Cpp? I was wondering if a translation to C++ code and then feeding that to the compiler of your choice will lead to a better result. Also how compatible is Delphi2Cpp with Delphi code containing generics and that stuff?

Strange... I get AV in RTL150.BRL ( Delphi XE ) on exit after installing #TestInsight (1.1.2.0). Uninstalling it solves the problem. Any hint?

Who's going to EKON 19 in Cologne, Germany, Nov 2-4? I'm not actually attending, but I live in Cologne and would happily meet up with anyone who's attending and feels like a beer or a tour of the city, including if you want to get out of the touristy parts. I've met up with a few people from this community over the past year, and it's always been great. Nice to put a face to a name and talk Delphi. Also, if you've never been to Köln before, with my deep local knowledge I can assist your decisions about what kind of Kölsch to drink (yes, some are better than others) and what kind of Altbier to drink (none, you Düsseldorf heathen.)

I stubbed out the function. That means it's like 99% done, right?

Looking for some screenshots of nice Windows apps developed in Delphi.  Most interested in the UI, well laid out, appealing, etc. Any chance a repository exists somewhere for inspiration for those of us who are graphically challenged?

Does anybody know any benchmark stats comparing TurboPower Abbrevia with TZipMaster? PS, years back I've done a very rough comparison (just be watching a stopwatch) between TZipMaster and another commercial one, TZipMaster wins. Now I see Abbrevia gets updated constantly in recent years and want to see if it is a viable alternative option. http://delphizip.org/

Generics T constraint TMyClass = class private   FReference: T; public    property Reference:T read FReference write FReference; end; T needs to be either a class or a record but you can't combine those constraints.  The obvious workaround is  TMyClassC = class(TMyClass ); TMyClassR = class(TMyClass ); That is a bit annoying :P

We have migrated to Delphi X Seattle.   We now find that many of our DUnit tests fail because the overridden constructor for our descendants of TTestCase is not being called. Anyone know why that is?  Did DUnit change?  And how do you create a class without calling it's constructor, for heaven's sake?

Does anyone know how to get hold of Jacob Thurman apart from his G+ and Embarcadero email account? I think the Castalia website has been hacked - there are spam blog posts, and have been for several weeks, and I've been trying to let him know. Look at the last three posts in the feed here, for example:  http://www.delphifeeds.com/feeds/186 http://www.delphifeeds.com/feeds/186

Hello guys, I am surfing on a strange problem, please took a carefully look at the image below, The full code is hosted at https://gist.github.com/horaciojcfilho/c72a921b81ce65e9f218 My constructor is overloaded but the Delphi IDE highlight it like it was not marked with "overload" directive. I don't know what is going wrong :( Thanks :D

I just wonder... How do you test VCL components? Do you use DUnit, DUnitX or similar tool?

Christian Pradelli has just released a new and exciting IntraWeb Bootstrap Library. It requires IntraWeb 14.0.38 or later (so Delphi 2009 to 10 Seattle are supported). This new framework is free and open source, and is hosted on github. You can also find a complete online demo! Enjoy! https://github.com/kattunga/IWBootstrapFramework

is that a seattle regression ? hit F1 on a warning message "no help for dcc32"

I have a Firemonkey form containing 2 frames, with each of those frames containing a wide assortment of controls.  I need for the form to be able to determine which of the 2 frames currently has the "focus". Although the docs say that TFrame has an OnActivate event, that doesn't appear to be true.  Is there a way I'm overlooking to determine which frame has the focus (or one of its controls) w/o having to trace through every child / descendant control in the frame?

Does anyone know how to export/import DDevExtensions options?

Hello guys, Does anyone can explain how do I implement  System.IEnumerable interface? I have tried to make my class implement that but I was not able to achieve that. Implementing that I can use it on string.Join method for example and many other RTL methods :D Thanks a lot :D

About debug visualizers, a problem I want to solve, evaluating the expression 'Addr(foo)' returns the correct pointer but it seems accessing that pointer casted to its correct type produces strange av afterwards, no useful stack trace. Found Cnpack developer had the same problem: http://bbs.cnpack.org/viewthread.php?tid=3323 explanation seems to be the address lives in a different virtual space, which I have no idea how to overcome.

Hello! I have had an email exchange with Randy Jacops . So far, he's been very pleasant to talk to and seems to be far better than previous management. He's also demonstrated quite a bit of guts by making his address available to some customers. I am sure he's received a lot of emails from many of us and I am sure our passion has shined through. Let's see how he conducts himself, but so far it's a thumbs up from me. A

My favorite refactoring key!

I've just had an epic derp moment... I inherited a form, add a few new controls and the related scaffolding. Then I thought - wow - it would be nice to have a generic type property on that form - so I added to the declaration of the inherited form, and used the type in a couple of non visual related methods.  Saved, close the unit, instantiated the form elsewhere, using the appropriate T substitute. The form shows up and goes BANG on the first new control reference in the code.  It was nil. All the new controls were nil. I open the new form - or rather I try: Parent not found - so I can't open the form designer. Turns out that adding a generic wasn't such a good idea after all. Interesting that it compiled, really - considering the visual inheritance was totally broken. Edit: But it would have been super neat! :P

Hi! i'm asking for a suggestion, or any idea .... how to debug android services with delphi ?  difference in debugging  between intent service and local service?

Hello,  I created a embedded forms in runtime using TTabControl the creation was fine but i stuck in how to determine the open tabs so it wont create(self) again when i click on the same button ? this code for the adding forms in TTacbControl  procedure AddForm(EmbeddableForm: TCustomInfoFrame); begin   EmbeddableForm.Show(MainForm.FaceP);   MainForm.cxTabControl1.Tabs.AddObject(EmbeddableForm.Caption, EmbeddableForm);   ResizeTabsWidth;   ShowForm(EmbeddableForm); end;

1st time it happened : I've created a new form, renamed it and saved it. Worked 3-4 hours on it and saving work in progress from time to time.... Closing the IDE and running it again... Loading my project, trying to compile it but IDE failed with "unknown error" exception (catch with madexcept). Previously saved form (pas + dfm) was missing... I only see trace of them on the _history folder....

Running Delphi in BlueStacks Android Emulator Hi All See here: http://www.delphifan.com/forum/Thread-Using-Bluestacks-as-emulator I have tested and it seems to be running my test app. The debugger however doesn't seem to connect, but the app is running perfectly. I will try and get everything working shortly. Stiaan http://www.delphifan.com/forum/Thread-Using-Bluestacks-as-emulator

in our team we "recently" {about 3 months ago} upgraded Delphi IDE from 2007 to XE8; I estimate we spent about 80 manhours to migrate our project. We have about 2 000 000 lines of code in our project group. Then we spent about 40 manhours to eliminate migrational bugs. Yes after we finished initial migration phase we discovered that tons of bugs were introduced in our apps as a result of migration. Now about #delphi   XE8. Code completion still barely works, houglasses argh. The IDE crashes. Code navigation barely works, often goes to wrong line or nowhere at all. I wonder if it was worth upgrading at all. Looking back seems like upgrading the IDE was a barely justified decision. Thanks Embarcadero

In Delphi XE10 Pro, the code that sets custom StyleLookup to TTreeViewItems and TListViewItems created at run time, DON'T WORKS. It shows only the text assigned to the Text property. It's absurd! And I can't find how to do this in Delphi XE10 Seattle. Al my applications use TTreeViews and TListViews with custom StyleBook assigned at runtime. For me it's very important solve this.  I'm totally blocked with this issue.  I don't know if it's a bug. I know that this components has been suffer a refactoring process, but I can't find help about how to make this in Delphi XE10. I can't assign a custom Style to the TListViewItems and TTreeViewItems created at run time.  Does any one have the same problem?  And the solution?  Thanks!

Hi Guys I'm trying to port our Firebird 2.0 database to Interbase to be used with Interbase ToGo. The issue I have currently is with some of the external functions like CHAR_LENGTH and TRIM. These were available natively in Firebird, but it seems it must be imported from the external UDF library using Interbase. I have found the DLL in the Windows IbToGo distributions, but I don't see it in the Android distro. Can someone give some indication if these libraries are build into the Android SO library? Much appreciated! Stiaan

Anyone know where I can find info on class constructors/destructors. It seems that class destructors never run when used in runtime packages, at least that's what I'm seeing. Wondering if that's as designed, or a known issue? Any references? The help wiki doesn't say much -  http://docwiki.embarcadero.com/RADStudio/Seattle/en/Methods I'm trying to clean up my shutdown code so I can see the wood for the trees in the fastmm leak reports.

Quick question - I haven't got the latest and greatest around to check, but I am right in thinking Seattle supports attributes added to methods in generic classes? If so, when was support added? In XE3 (which I'm currently working with), attributes added to methods in generic classes are just ignored, i.e. enumerating the RTTI of an instantiation of the generic doesn't come up with any attributes for the methods concerned.

Hello all, Please, your inputs are needed in this question. Thanks. http://stackoverflow.com/questions/33322821/tracking-down-and-fixing-annoying-access-violation

On last Thursday (22nd), there was the first Australian Developer Day, ( http://ausdd.embarcadero-info.com/ ) sponsored by Embarcadero Technologies. Malcolm Groves was quite worried about the weather (it seems that when it rains in Sydney, people don't turn up - personally, I wouldn't turn up if it was good weather... off to the beach but I digress) but it held out long enough for people to arrive and once there, they stayed. I did over hear someone say that they came for one or two sessions but in the end stayed for the entire day - yet again, I digress. shane van de Vorstenbosch was there giving away some copies of his "The Rotten Cookbook" ( http://rottenfoodcookbook.com.au/ ) - I can't wait to make up some of those dishes for work!! ;-)  During the sessions, some information was "leaked" out by people such as Malcolm Groves, David Intersimone and Damien Bootsma. Such items that were leaked were such things as: * Compile to Linux coming next year - So...

I know I'm late to the party here, but can anyone tell me why, in DUnit, they changed the XML output format in XMLTestRunner.pas? I discovered this change as part of the move from XE to DX Seattle.

Hi, I'm using TActionMainMenuBar in a software of mine compiled with #10Seattle. I'm noticing an annoying pixel drawn between the first and second row of the pulldown menu. I could notice this also in the Delphi IDE as you can see in the picture below. Anyone can notice this pixel too?

Hi all, There probably is an simple way to find all dfm files in a project (or in a folder), that are saved in binary format (those that don't have "Text DFM" checked), I'm just not aware about it :) I want to set all such binary dfm files to "Text DFM". Can someone please point me in the right direction?

A curiosity, got BDS hang and found the endless running thread was at: codequerydelphi230.bpl!@Sqlitedelphiparser@TSQLiteDelphiParser@SimpleExpression$qqrv Name suggests SQLite is used to store parsing output, or SQ means anything else?

... and while I'm at it, has anyone noticed any change in the behavior of IsConsole?  I'm seeing it not work right when I'm running in the IDE.  Trying to write a test case, but I thought I'd ask.

Maybe I'm crazy, but I seem to remember that the IDE behaved differently than it does now in the following way: 1.  Create an app 2.  Build the app 3.  Press the "Run without Debugging" button Now my memory was that at this point, the IDE would not recompile the application, but instead run the EXE I created in step 2.  However, now it appears that the IDE does a compile and then runs the app. Do I have a poor memory?

I'm sure this has been entered in QC many times, and perhaps it will never be fixed.   Why can't the debugger display variable values with "With" statements.  I know, I know, don't use withs.  However, for old code that has withs, it's a pain.

Hello again! How do I strip the thousands separator from a string with a number in order to convert that to an Integer value? Ex.: 14.500 -> 14500 Thanks :)

So my Delphi XE6 install suddenly started doing this each time I fire it up: [Window Title] Error [Content] Can't load package c:\program files (x86)\embarcadero\studio\14.0\bin\dclmcn200.bpl. Registration procedure, VCLFormDesigner.IDERegister in package C:\Program Files (x86)\Embarcadero\Studio\14.0\bin\vcldesigner200.bpl raised exception class EActionError: The VCL framework is already registered. Do you want to attempt to load this package the next time a project is loaded? [Yes] [No] The bpl that triggers the complaint (dclmcn200.bpl in this case) changes, but the rest is the same. I haven't installed or changed any Delphi related stuff lately, it worked fine last week but this week it's been doing this consistently. Any ideas what this might be?

Did I miss something? What are those CodeRage X PREVIEW videos uploaded on Embarcadero's YouTube account? Description says: "Full video is available with an active Update Subscription" https://www.youtube.com/user/EmbarcaderoTechNet/videos https://www.youtube.com/user/EmbarcaderoTechNet/videos

Do you use UML Modeling Features ?

Is it possible to completely disable modeling functionality in #10Seattle?

Is there any Debug Visualizer to automatically cast object instances (and their properties/fields) to the right class types? (ie: I'm really TIRED of casting and casting and casting when inspecting instances)

Hi Marco Canto I see on TheRegister.Co.Uk that Idera bought EMBT. This creates some uncertainty, as I can still remember the Inprise saga.... I'm about to invest some serious money and effort using Delphi in a very big project, so I was wondering if we (The Delphi community) should be worried in any way? I would appreciate everybody's feedback as well. Regards Stiaan

Hi to everybody! In the last days I'm heavily working with #10Seattle in the maintenance of a huge unit where I keep all my customized components (about 40000 lines pas file). Sometimes it is really impossible to work for even minutes because the IDE freeze. During this freeze time one of the 8 i7 cores of my machine is working at 100% (I can hear the cpu fan spin faster!). Has anyone experienced the same behavior? In XE8 and previous versions I never see this kind of problem doing the same things.

FireDAC TFDBatchMove custom Mappings .. Has anyone have a sample of creating custom mappings for moving data using TFDBatchMove with a TFDBatchMoveSQLReader and TFDBatchMoveSQLWriter? I get an error: 'access violation at .. :read of address ..' I wrote .. var   I: Integer;   ABatchMoveMappingItem: TFDBatchMoveMappingItem; begin     fdbatchmove.Mappings.Clear;     fdmetaSource.First;     fdmetaTarget.First;     while NOT fdmetaSource.Eof do     begin       ABatchMoveMappingItem := fdbatchmove.Mappings.Add;       ABatchMoveMappingItem.SourceFieldName := fdmetaSource.FieldByName('COLUMN_NAME').AsString;       ABatchMoveMappingItem.DestinationFieldName := fdmetaTarget.FieldByName('COLUMN_NAME').AsString;       fdmetaSource.Next;       fdmetaTarget.Next;     end;     fdbatchmove.Execute;   end;

I give up... What is the required syntax when using variables in Select statements in SQLite? For example: SELECT firstname,lastname FROM members WHERE username=variablename Thanks!

Need a little help with SQLite and FireDAC. A pretty simple query where I look up a username and when found pull down it's associated fields into variables. But I need to do error checking along the way; i.e. if connection fails and if username is not found, etc. Basic code I am working with is below, would someone mind helping me tweak this code to take care of dealing with the error conditions? And of course if I have made an mistakes in my code to begin with. FDConnection1.DriverName := 'SQLITE'; FDConnection1.Params.Values['Database'] := 'C:\Users\Admin\Desktop\test_app\TestDatabase.db3'; FDConnection1.Open; query := TFDQuery.Create(nil);      query.Connection := FDConnection1; query.SQL.Text := 'Select password from Test_Table where username=usernameEntered'; query.Open(); dbPassword := query.FieldByName('password').AsString; dbName := query.FieldByName('Name').AsString; query.Close; query.DisposeOf;

I was asked to share this, so though it might be a fun for more people. It is a demonstration of pre-emptive multitasking in Turbo Pascal. I wrote this back '97 when I was 17 years old, using Turbo Pascal 7. You can register a number of tasks, in the form of parameter-less procedures, and the code will then switch between them pre-emptively, that is, without cooperation. It hooks interrupt 8, which fires every 18.2 ms or so, which triggers a task switch in a round-robbin fashion. It saves all the registers of the running tasks, find the next task to run, and restore all registers from that task. I recall spending an entire night studying the x86 instruction set trying to figure out how to save all the registers and flags in a way which would not overwrite the very registers or flags I was trying to save. The code here just has two tasks, one which processes keyboard inputs and one which draws something on the screen. Anyway, good times :) http://paste.ie/view/8d50f39c

The Embarcadero tech partner spotlight on Bookmarks and Navigator is up on Youtube! This is a short video, with a quick introduction to the two plugins followed by a live Q&A.

RTTI and method overrides Is it possible to see that a specific method in the (current) class has an override, using RTTI? Update: See my comment 12:02 - it was solvable without using RTTI or VMT trickery

Because datasnap loses connection to the client application FireMonkey? What is better? TCP or HTTP?

TestInsight 1.1.2 is finally available on  http://testinsight.dsharp.org It contains a few bugfixes and the long awaited Seattle support. For those using DUnitX - make sure to update to the latest version - Delphi Seattle users can use the bundled one. P.S. If you love the plugin - feel free to become a sponsor ;)

Hey guys, Sorry for asking it, but I wasn't able to find it, where do I add Program arguments to my project? I need to compile my program passing some command line arguments to test it. For example: pmt -e 2 -p patterns.txt data.txt Thanks a lot :D

HTML Component Library, HTML Report Library and HTML Editor Library 3.4 released. This version introduce a new rendering architecture: now drawing is fully separated from other library parts and can be implemented via any graphics library. For example you can chooose between GDI and GDI+ canvas in VCL or between FMX and native canvas on Android. GDI canvas (htcanvasgdi unit) is much faster than GDI+ and provide precise text rendering without GDI+ text issues, so it's use is preferable for text editing or displaying large text documents. But it has some limitations - rounded rectangles are not smooth and pictures support are limited by Delphi VCL, so for old IDE version only bitmaps and JPEG are supported, for XE+ also GIF and PNG. You can test it using compiled Editor demo (see link below) with live canvas selection. Android canvas (fmx.htcanvasandroid) provides much fasted and better rendering than default FMX canvas. Correct drawing of kerning pairs, precise baseline alignment, R...

Multithreading is hard. I often say this and, boy, am I right! Few days ago I've published a tutorial (link below) on updating a progress bar from a parallel for loop. Relatively simple code, nothing to go wrong, true? Wrong! Today I reviewed one of the examples as something was bothering me and then I noticed that all of the progress bar examples (that is, sections from 1.a to 2.c in the tutorial) are bad! Each of them can exhibit unwanted behaviour! While I prepare an explanation article and fixed code examples (which may take a day or three) you are kindly invited to find the problems in my code and post them here :) A winner (criteria will be the number of bugs found and quality of explanations) gets a free copy of my "Parallel Programming with OmniThreadLibrary" book plus free access to my "High-level Multithreading with OmniThreadLibrary" webinars.

Does anyone have any recommendation for SIP telephony components for a Windows IVR application ?

I need to get a better understanding of using multiple forms in a project. What are the best practices? Differences between mobile (Android) and Windows, etc. I've built my Android app using a single screen and am hiding/showing different elements at runtime. Works well but what a mess it has become. In hindsite using different screens/forms may have been a better idea. But I have no idea how to do this. Can someone point me to a tutorial or some sample code that I could look at that would explain how to create an app that has a main form that then calls a 2nd form from say a button press, then on exit goes back to main form? Thanks much!

Just wondering what peoples comments on live bindings are? What limitations there are (to which version)? What gotchas for people who are new to it? If you haven't used it, any particular reason why?

It seems that BitDefender thinks that Nick Hodges is going to harm your computer... What are your evil plans Nick? And can I be a part of it too?? ;-)

So my last post about with statements was about me using one, and instantly realizing "what I had done." This post about with statement is just to make your eyes bleed. Courtesy of the VirtualTrees.pas...   with FHintData, FDrawBuffer do Now who's idea was it to allow with to use more than one variable at a time? Why this insanity? LOL! It's almost as if the developers are DARING me to figure out what they are doing, heh.
