How could i used TDirect2DCanvas in delphi7 ?

Hello. I have an .inc file which contains ...   {$IF (CompilerVersion >= 14)} {$DEFINE Delphi6} {$DEFINE Delphi6up} {$IFEND}   {$IF (CompilerVersion >= 15)} {$UNDEF Delphi6} {$DEFINE Delphi7} {$DEFINE Delphi7up} {$IFEND} ... Delphi 7 compiler gives an error "constant expression expected". What am I missing here? Thank you.

Hello! I'm learning Turbo Pascal. Should I learn Delphi after Pascal?

XE5 and Android. Had a hard time until the first app did execute on the emulator. Until then, the screen of the emulator just remained black. When starting the emulator from the Android Tools instead of letting it start by Delphi I noticed a log entry which finally did lead me here: http://code.google.com/p/android/issues/detail?id=33336 Adding the appropriate folder to my path environment did do the trick for me. Hope this is helpful to anyone :)

Hello. I have just uploaded a new release of my free open source Delphi Component Installer. http://ddobjects.de/free-software This release contains bugfixes and many tweaks, includes command line compilation for MacOS (Delphi XE2 to XE5), considers Delphi specific environment variables (those which are defined and/or overridden within the IDE) and supports compilation using the VCL and Firemonkey frameworks. http://ddobjects.de/free-software

Why can I FreeAndNil() a Delphi string? That's just wrong on so many levels. But I'm assured that it not only compiles, it runs. Please explain! Well, in the "no immediate error" sense. Strangely, just after that I start seeing access violations. Does anyone know why?

Code SOD for the day: someone has left me a pile of code where they use "var" on object parameters to mean "contents of object are changed in this method". I am having to learn how to read that code (while I clean up huge numbers of memory leaks).     procedure PopulateList(var aList:TList);     begin          for i:= 1 to 1000 do              aList.Add(MakeNewObject());     end; To me "var" on a parameter means "this thing will change", and on an object that means "this gives you back a different object", as in WalkDownTheQueue(const aQueue:TQueue; var aCurrentObject:TSomeObject); in which example we will ignore the oddness of that particular method. The worst part of this is that some of those lists contain heterogenous objects. But at least Delphi has a common ancestor and sensible inheritance, so I can just call .Free; on them and move on. Assuming, that is, that the contents is actually an object. And references are unique. Both of...

Hi, for everybody who watched the CodeRage 8 session - Escaping the Try..Finally..Free Nest from Allister Christie - and hwo actually likes this way of doing it, you might want to check a Live-Template that I made, which simplifies the declaration of the Guard significantly.

OK, I'm getting desperate. In my new job, we are using Hg, and I am working from home, on a VPN. Any and every remote action I attempt results in: abort: unexpected end of stream. I have googled, and found that many people have experienced this error, but the claimed solutions are almost as numerous as the complaints, and none have worked for me so far. One which sounded hopeful was to disable stream compression, but it only took longer, and resulted in different error. Oh, and the byte count is generally within 95% of what it should have been. Also, we are using the TortoiseHg Workbench, not command line. I am open to almost any suggestion.

Hello there.... Have somebody help me about, How to compilation TpMath in Delphi 2010..??? Thanks in advance...

So in this video[1] I learned something new, that you could inherit an interface from a reference to function/procedure declaration.

I have a MainForm, with a panel. What I would like is to show any other forms in the panel of the MainForm itself. I've been playing with the Align and Parent properties, but they don't seem to do the trick. I used to use a 3rd party component to achieve this, but I believe it is possible within Delphi itself.

How could i make forms into a dll so that when i place the dll in application directory i can use that form....

Hi every one! I want to use FastReport with a Database, where the field 'sex' is represented in the DB as '0' for 'male' and '1' for 'female', but I want to print it as 'male' , 'female' not '0', '1' I asked around and they gave me that code : procedure TForm1.ADOTable1sexeGetText(Sender: TField; var Text: string;  DisplayText: Boolean); begin   if Sender.AsString[1] = '0' then Text := 'Male';   if Sender.AsString[1] = '1' then Text := 'Female'; end; but it looks like this code works only with AdoTable, not with AdoQuery procedure TForm1.ADOQuery1sexeGetText(Sender: TField; var Text: string;  DisplayText: Boolean); begin   if Sender.AsString[1] = '0' then Text := 'Male';   if Sender.AsString[1] = '1' then Text := 'Female'; end; Any ideas?

DDevExtensions 2.8 released for RAD Studio 2009-XE5 One feature of DDevExtensions that may interest those with out of memory issues when compiling larger project groups is the "Release compiler unit cache before compiling". It is turned off by default. Description: If you compile large project groups the compiler’s unit cache can occupy a lot of memory for each compiled project. This can lead to “out of memory” exceptions. DDevExtensions can be set up to release the compiler’s unit caches of the projects that are already compiled. It is also possible to only release the caches if the IDE’s memory usage is high so CodeInsight doesn’t get a performance hit due to a released unit cache. http://andy.jgknet.de/blog/2013/11/ddevextensions-2-8-released-2009-xe5/

From the Redundant Department of Redundancy...     if (_List = nil) then     begin       try         _List := TStringList.Create;       except         _List.Free;       end;     end; Never mind the fact that the code references _List immediately afterwards without checking if _List is nil or not...

I do not think the XE5 adding a Soap Server Interface, it disappeared??

Hi I have created a mobile application for android and ios with Delphi XE5. I needed a custom component, so I created a package and I wrote my component. I wrote a windows application for testing my custom compnent and every thing is OK so far. I add an instance of my component on the Firemonkey mobile form in design time and it shows it correctly. But when I try to run app on IOS Simulator or Android emulator it crashes, I think the problem is caused by not deploying my package along with my app, but I don't know how should I include this package in my mobile app deployment. Any idea? P.S I know how to deploy database files to Android and IOS

I'm curious if anyone out there is successfully using Hunspell spell checker with Delphi XE2 or above.   If so, what's your secret?

I kinda feel I should know this. How can I get the address of a virtual class method, given an instance? I want to pass it as a regular function pointer. Any relatively nice ways without using an asm block?

Having been away from Delphi during the "Generics revolution" and recently returning, I've been stumped by some of the seemingly weird limitations. Biggest one is functions/types used by a generic method having to be specified in the interface section of a unit. Then today I stumbled across this erronous error, which I guess confirms what I thought for some time, that the above inconsistencies are due to generics being implemented using the same infrastructure as code inlining. Just coincidence or anyone know for sure one way or the other? type   TRec = record     procedure Proc ();   end; procedure TRec.Proc ; begin   asm end; // E2426 Inline function must not have asm block end; begin end.

What more to say except that Andreas Hausladen is on the job :-) http://andy.jgknet.de/blog/2013/11/ide-fix-pack-5-4-for-2009-xe5-released/

Help needed with blob fields OldValue and NewValue - On Delphi XE I'm using OldValue and NewValue from TpFIBDataSet(but it can be applied to any TDataSet descendent) in order to verify if different fields have changed. My questions is how can I retrieve these 2 values for the blob fields as TMemoryStreams? I've made some research, but I found nothing. Any idea on this? http://stackoverflow.com/questions/19710472/delphi-how-to-get-datasets-oldvalue-and-newvalue-for-a-blob-field http://stackoverflow.com/questions/19710472/delphi-how-to-get-datasets-oldvalue-and-newvalue-for-a-blob-field
