I checked the CoInitializeEx and getting RPC_E_CHANGED_MODE for COINIT_MULTITHREADED.
If I use COINIT_APARTMENTTHREADED, then I get S_FALSE back, meaning that the COM library is already initialized.

I believe I move on now for always DPL.Create ... DPL.Free, for each execution of the tread, and will check later how is it behaving in XE4 or later.

Sorry for the late reply, I was out of town. Currently Delphi 7, and will also try with Delphi XE4 (or XE5)]]> Mon, 05 May 2014 11:21:11 +0000 http://www.quickpdf.org/forum/quckpdf-in-a-thread_topic2881_post11676.html#11676 <![CDATA[QuckPDF in a thread : Which type of the Debenu library...]]> http://www.quickpdf.org/forum/quckpdf-in-a-thread_topic2881_post11665.html#11665 Author: tfrost

Which type of the Debenu library are you using (static Delphi, DLL, ActiveX)?]]> Wed, 30 Apr 2014 12:16:19 +0000 http://www.quickpdf.org/forum/quckpdf-in-a-thread_topic2881_post11665.html#11665 <![CDATA[QuckPDF in a thread : I changed my solution that I do...]]> http://www.quickpdf.org/forum/quckpdf-in-a-thread_topic2881_post11664.html#11664 Author: Chopinke

I changed my solution that I do the .create and .free inside the thread running. I am not sure why would I even have to call CoInitialize, because

1) They already fixed that issue in much earlier version
2) They claim free of Adobe Reader, so why do they need any OLE stuff?

But I will try the CoInitializeEx() and let you know the result.

Have you tried CoInitializeEx?]]> Wed, 30 Apr 2014 10:19:27 +0000 http://www.quickpdf.org/forum/quckpdf-in-a-thread_topic2881_post11663.html#11663 <![CDATA[QuckPDF in a thread : Hi,I am evaluating QuckPDF library...]]> http://www.quickpdf.org/forum/quckpdf-in-a-thread_topic2881_post11661.html#11661 Author: Chopinke

Hi,

I am evaluating QuckPDF library with Delphi7. I am using threads.


constructor TMyThread.Create(CreateSuspended: Boolean);
begin
  inherited Create(CreateSuspended);
  Priority := tpNormal;
  FreeOnTerminate := false;
//  CoInitialize(nil);
  DPL := TDebenuPDFLibrary1014.Create;
  DPL.UnlockKey('blabla');
end;

destructor TMyThread.Destroy;
begin
  DPL.Free;
  DPL := nil;
//  CoUnInitialize;
  inherited Destroy;
end;

procedure TMyThread.Execute;
begin
while not Terminated do
  if not Suspended then
  begin
      PDFDocument := DPL.NewDocument;
  end;
end;

I am getting 'CoInitialize has not been called' exception at the NewDocument() call, even if I uncomment the CoInitilalize in the code above.

What the problem may be?

Thanks!
