Hello

used tools:

Delphi Xe7, Debenu 11.12, Win32 project, Win7

Code that raised access violation exception:


  FDebenu.SetDPLRFileName(ExtractFilePath(ParamStr(0)) + 'DebenuPDFRendererDLL1013.dll'); // returns 1
  FDebenu.SelectRenderer(3); //returns 3
  FDebenu.LoadFromFile(FDocument, '');
  FDebenu.SetMeasurementUnits(2);
  FDebenu.RenderPageToFile(FDPI, page, 0, 'c:\temp\aaa.bmp'); //here I have access violation exception

What can be reason of the exception?

Thanks a lot.

If the exception is occurring in the rendering DLL, I suggest you open a support ticket with Debenu and send them details of the exception address (from the exception) and the load address of the DLL. You can find the latter by viewing the process in Process Explorer and typing control-D, and this procedure will also allow you to verify that the exception address is within this DLL. Debenu support should also be able to tell you whether this issue is likely to be fixed in the current release.

Thanks for the answer.

problem for support forum is I have demo trial version of the library and can not be registered on support forum.

without good PDF rendering quality it does not matter to buy the library...

but here we have trouble and exception inside DLL.

Exception is obvious NIL access try:

access violation at 0x00000000: read of address 0x00000000.

Maybe problem is I use library 11.12 and renderer 10.13... Maybe versions are incompartible.

You can go to http://www.debenu.com/support/issue-report" rel="nofollow - http://www.debenu.com/support/issue-report and say you are a trial user. I am sure Debenu will want you to buy their product!
