We're thinking of getting Documentation Insight Enterprise.   I'm evaluating it as we speak.  Does anyone know how to get the code in the DPR (project file) to show up in the document explorer and the generated html and chm files?  I'm trying to document some DLL's, and our exported functions are in the DPR file, and while you can document the dpr (using the inspector, which then shows up in the source),  the document explorer and the generated chm and html files don't show anything in the dpr file.

Can anyone think of a reason why someone would write:    if (aRecordSet nil) and ((aRecordSet.State and cardinal(osStateOpen)) = Cardinal(osStateOpen)) then     begin       aRecordSet.Close;     end; instead of just:    if (aRecordSet nil) and aRecordSet.State = adStateOpen?     begin       aRecordSet.Close;     end;

Today's gem is brought to you by not understanding "not": procedure TSystemSetups.edNoNumbers(Sender: TObject; var Key: Char); begin if (Key in ['A'..'Z','a'..'z']) then Key := #0; end;

Having a look at DunitLite ( https://code.google.com/p/dunitlite/ ) and came across a compiling error under Delphi XE which I don't quite understand. The following class doesn't seem to play nice:   TSpecification = class(TInsulatedTest)   strict protected type     Given = Specifiers.Given;     Should = Specifiers.Should;     Specify = Specifiers.Specify;   end; When TSpecification.Should or any others are used, the compiler reports: [DCC Fatal Error] ConstraintTests.pas(683): F2051 Unit ConstraintTests was compiled with a different version of Specifications.Should However, if the following is used   TSpecification = class(TInsulatedTest)   strict protected type     Given = class(Specifiers.Given);     Should = class(Specifiers.Should);     Specify = class(Specifiers.Specify);   end; It compiles fine. Dunitlite seems to be written for Delphi 2005+ (as it uses the for-in syntax) but breaks on Delphi 2010+. Does anyone know why the second class definition needs to be used, as I t...

Uglypattern of the day: MyObject := nil; try    MyObject := TSomething.Create();    ... finally    if assigned(MyObject) then       MyObject.Free; end; It's so close to being right. So close.

Does anyone know how to replace the serial number from Delphi XE4 professional to an enterprise serial number?  I inadvertently gave a co-worker the wrong serial number, and he should have gotten an enterprise serial.   I have the enterprise serial number available.

Multithreaded painting in Delphi? Yes it's possible! I did some quick hacking to see if I could make painting in a subthread possible (TCanvas etc). I made a stress test with FastReport printing in a subthread and heavy TMS painting in the main thread. Initialy I got acces violations in GDI32.dll after 18 pages, but I have now over 400 without problems! (in FinePrint, to save the trees :) ). The main problem in Delphi VCL Graphics.pas is the usage of a global var for "StockPen", "StockBrush" and "StockFont". These global vars are used for each paint, at least when you change the Canvas.Pen etc (and you do, if you want to paint something :) ). After changing these globals var into a threadvar (which is slower!), the same for FontManager, PenManager and BrushManager you get multithreaded painting in Delphi! (tested with 2010). Next problem are memory leaks: stuff needs to be cleaned up after each thread termination... Note: I had to save Graphics.pas to ...

I have just addressed a performance issue in XE4 (without update1). My parser benchmark program took 600ms when enabled Compile->Debug Information option in XE4. It only took 60ms in XE-XE3 with same project configuration. When I disabled the option in XE4,  it is ok. (Optimization option doesn't have an impact in this case) Did you meet this situation?

So what's your thoughts on this? I like the 3.14 multiplier, but often use the IBM calculation - upgrade the estimate to the next unit and multiply the value by two [used for developers that we know have bad estimations]. eg: 1 hour estimate becomes 2 days. :) http://coding.abel.nu/2012/06/programmer-time-translation-table/

A gentle request to users of our products.... It is a problem that every time we make a release of kbmMemTable, then  between 1 and 3 weeks after, it has been leaked on Chinese websites,  shortly after followed by others. Since its happening constantly and every time we make a release, its  obvious that its not by accident, but rather that its being deliberately  done by a registered user. It is utterly and completely unacceptable that this is continuing to go  on, and it makes me question what actions should be taken. Due to the leak issues previously we moved all our software downloads to  the portal, trusting that paying users probably would be less inclined  to leak the software, than non paying hackers. The move to the portal has obviously made life a little bit more  complicated for people purchasing, since they have to go through the  request license procedure. Unless legitimate users stop leaking our software, then a next step will  most likely make it even more cumbersome to ...

Hi all I'm new to Delphi - 2 weeks ago started with DelphiXE4 & want to learn Delphi language..how do I add FMX.Edit; to a project? (What is FMX.Edit; ? it appears necessary for some drag&drop code I am trying to setup)? Steep learning curve ahead.... :-)

Hi Folks, have you ever tried to "invert" the language of an application? The situation is as follows: We have an application whose UI is originally in German, since most of our customers are German. Modules that are shared with other applications have an English UI. All other applications UIs are originally in English. We are using gnu gettext to translate our UIs into the target language, so for this particular application we have hodgepodge->English, hodgepodge->German, hodgepodge->other language .po files. My goal is now to convert the original GUI of the application to English, so we can get rid of the hodgepodge->something translations and make life easier for future translators. My current idea is to do it in Delphi. I want to use xgettext to load the hodgepodge->English .po file, loop over all dfm and pas files and apply the "reverse" translation to them, so all original strings are English afterwards. Sounds easy enough, since xgettext alread...

I'm experiencing a weird issue with "zombie processes", and I'm curious if anyone has experienced anything similar. We're using Task Scheduler to start our program every 3 minutes. The program imports some data to our database and outputs some files. It's part of an integration solution. The program runs from local disk on a MS Server 2008 in a "cloud VM". Now, the problem is that sometimes the process simply hangs after the call to "end." (the final end that is). Task Scheduler somehow doesn't understand what's going on and does not terminate the process. To avoid this issue I wrote a "watchdog" program. The main program aquires a named mutex before shutting down, and never releases it. When aquiring the mutex, it writes it's PID to a named memory-mapped file. After aquiring the mutex it writes to a log file and then it calls "end.". The whatchdog tries to aquire this mutex for a minute, and if it fails to d...

Could someone point me in the direction of some good  resources on Delphi component development (VCL or FMX)? I've been trying to get into component development for years now, but I usually end up giving up after a couple of days. I've picked up some tricks from studying existing components, but I'm looking for actual guides/tutorials to get a better understanding of the actual process and it's complexities. The docwiki does have some interesting information on the concept, but it seems to be limited. I don't mind buying a (e-)book if that's necessary.

A small tip about Character Encoding: If you directly write any Non-standard ASCII characters (>#127) in source code, please save the file as Unicode such as UTF8/UTF16. Otherwise, the source file may not be compiled.  The following function was copied from SynEdit project (SynEditSearch.pas), it works well in CP-1250, but you might be surprised what it looks like in other code pages (like CP-936, Simplified Chinese).  You see, there is not even ending single quote char. Do you know why? Take the character "°" for instance, it was saved as a singel byte #176 in the source file. This byte is regarded as a leading byte in DBCS code pages (as it is greater than 127) and the subsequent single quote byte will be taken as trailing byte so that the two bytes will be interpreted as a character. As this combination is invalid in current code page, it was translated with a question mark "?". So ... compiler failed. In addition, this kind of function is also not friendly(co...

So I know that the FastCode project pretty much stopped with the introduction to Delphi of Unicode, but is anyone using any string libraries with XE? Or is it all just so superb that no add-ons are needed?

Not tremendous useful today as when developed (Delphi 2010 time frame) but, if someone is still using my DataSnapFiltersCompendium, now can find the XE4 version on google code. http://www.danieleteti.it/2013/06/18/datasnap-filters-compendium-updated-to-xe4/

I'm still hoping to release one or more of my components as open source this year. In looking at my third party components (some open source, some proprietary), some are compiled with debug options ON, while others are compiled as release versions. As component users, which do you prefer?

I am trying to read a Unicode string from memory but I am not getting it right. The string I am attempting to read is "EMyExceptÙion" but what I am getting back is "EMyExceptATion" (the Ù turned in to AT). My code is as follows: SetString(LNameStr, PAnsiChar(PByte(LName) + 1), Byte(LName^)); Where LName is of type PAnsiChar to the text, with the first byte being the length of the string (similar to a short string?) I have tried a few things but I haven't got my head around text conversion :(

Confirm using const Epsilon slowdown fmx apps (and maybe not only fmx). So: xe4, x32, when using constant Epsilon from System.Types module it takes too much time, and looks like that delphi act it as not Single, but extended or double and makes some conversions. If replace it with just 1E-40 as declared, it goes very much faster! Set {$EXCESSPRECISION OFF or ON} or Debug-Release configs  - don't care on result. And if  take into account that fmx use this constant about 40 times only in FMX.Type module we can see very slowdowning all apps done with fmx!

Does anyone know of any limitations to the number of attributes that a class and/or method and/or property can have?

Small survey for component developers: How do you sell/distribute your components - as opensource, as .dcu or  as .bpl ?

Do you have problems with closed source components (ie upgrading to newest IDE versions) ?

We are searching for a flexible DBGrid component. It should be able to group data and still be rather fast. E.g. we want to display products with variations or product-sets. The 'father-product' should be displayed in the grid. When it is expanded, the variations should be listed below. Does anyone know a component that can be used for this case? PS.: A nice additional feature would be an automated refresh of the data inside the grid.

Looks like TIOBE isn't alone in differentiating Delphi and Pascal, other popularity indexes have the same issue: - http://www.langpop.com/ -  http://lang-index.sourceforge.net/ Other indexes don't show the "runners up", so they may differentiate as well. For both indexes above, merging back Delphi & Pascal brings it back in the top 10.

Does anyone know what the IDE does upon start up? At home in a VM virtual machine, XE3 and XE4 starts fairly quickly. It just happened that over the weekend, I was hospitalised and at the end of my stay, I had my laptop in there (to keep me occupied) and found that XE3 took ages before showing the splash screen and XE4 splash screen hanged for a little while before continuing. I am guessing that both were trying to phone home (to Embarcadero) - Does anyone know if this true or not? I also found that if the IDE was open and I double-clicked on a project file in Windows Explorer, the IDE would hang for a little while - attempting to call home again? If the IDE is calling home, why does Embarcadero (and every other company that does this type of thing) assume that everyone has internet connection? and couldn't this be done in a background?

Delphi XE. Create a new form, File Save As...  I get External exception C000001D. This, of course, in the wake of this morning's madness. What a day....

This morning, RAD Studio XE, on opening, gives me an AV, which appears to be related to CommCtrls.UxTheme in some way. The AV is persistent, it repeats endlessly, and always reports the same address, even after a system reboot. If anyone has any suggestions to offer, I would appreciate it. As it stands, it is opening a project by default, and I'm still looking for files to delete to clear that. How can I (from outside the IDE) clear the default project?

Hoping someone can point me in the right direction on this. I'm busy evaluating Delphi XE4 (trail) and am trying to build an IOS application.

What is the justification of use .inc files to declare and implement code is some RTL units?  Starting with #Delphi #XE2 many of the new RTL units related to Vcl styles, OSX and so on, uses inc files to declare types, classes and implement code (just like the FPC does), what is the justification to do that? you can see what i mean if you inspect one of these folders (source\rtl\posix, source\rtl\posix\osx, source\rtl\sys )

I'm looking at the hints from JediCodeFormatter and Pascal Analyzer and when I see one in Primož Gabrijelčič code I go "he knows what he's doing" but when it's in my code I go "must fix!". That's probably the voice of experience speaking... JCF complains about the deprecated REAL type in gpTimeZone, but I suspect that could be because our version is very out of date since it is dated 2000 and comes via ESB.

for-in done the slow way: for Item in MyDictionary.Keys.ToArray do ...

JCL and JVCL are now both available at GitHub. Only the git master branch supports XE4. https://github.com/project-jedi/jvcl

We have a RemObjects SDK based server and we would like to write a web based client that can interface with it. It will need to display quite a lot of records in grids. Does anybody have any recommendations or suggestions on a nice way to do this. We have used ASP.NET before, but it was not the greatest experience ever.

I do use that object... procedure TClassInstanceDictionary.SendNotifyTelegram(const id: Integer; const tlg: TPSDTelegramBase); var   Obj : TBaseClass; begin   Obj := Items[Id] as TBaseClass; //   Obj.SendNotifyTelegram(tlg); end; [dcc32 Hint] SomeUnit.pas(xxx): H2077 Value assigned to 'Obj' never used

Nick Hodges started a thread here https://forums.embarcadero.com/thread.jspa?threadID=88003 . Regarding the promotion of Delphi, one of his statements says:  "Giving it away (or selling it for really low prices) in schools. Schools react, they don't lead. It's a huge effort with little return.". I'm not so sure about this. I know I started using Pascal/Delphi in University. My question is, what got you started with Delphi? https://forums.embarcadero.com/thread.jspa?threadID=88003
