Hi Igor,

like TFROST told already...
You should check where you're doing the CREATEs and FREEs.

Cheers and welcome here,
Ingo

What type of stream are you passing to the function?  Have you checked that the stream has been created and has not been closed or modified by one of your other threads?  If you are writing direct to a filestream have you tried instead changing to a memorystream and then writing that to file later?  When you run the application under the debugger what does the stack trace tell you when the exception occurs?  What version of Delphi and Debenu are you using?  Google indicates that c000029 may be related to a stack corruption issue: so can you reproduce the issue if you single-thread your application?]]> Tue, 10 Jun 2014 15:28:07 +0000 http://www.quickpdf.org/forum/rendertostream-crash-application_topic2919_post11782.html#11782 <![CDATA[RenderToStream crash application : From event viewer:Faulting application...]]> http://www.quickpdf.org/forum/rendertostream-crash-application_topic2919_post11781.html#11781 Author: Ihor.Karalash

I have many threads that use RenderToStream for writing document data to stream, very often i get access violation here, sometimes i get error message with link to ntdll.dll, sometimes "System error. Code 5".

function TPdfDocument.RenderPageToStream(dpi, page: integer; output: TRenderOutput; target: TStream): boolean;
var
    res: Integer;
begin
    try
        res := fLib.RenderPageToStream(dpi, page, Ord(output), target);
    except
        Exit(False);
    end;
    Result := res = ERR_Ok;
end;

And after some time, application crash and close without errors. Any ideas? Windows 7, x64
