pdfMakeJpeg memory errors

Hi,

I have recently included the pdfMakeJpeg feature of WPViewPDF into my program (using Delphi 2005) but every time I include the following line :

function pdfMakeJPEG(filename: PChar; password: PChar; licname, lickey: PChar; liccode: Cardinal; destpath: PChar; frompage, to_page: Integer; jpegres: Integer): Integer; stdcall; external 'wPDFView02.dll';

my application will not load and get an error that reads:

"The instruction at "0x00553b56" referenced at "0x00da2af0". The memory could not be "read". Click OK to terminate and Cancel to debug."

If I remove the declaration of pdfMakeJPEG, my program loads fine. What could be causing this error? I have even included this in a brand new sample project with the same error.

Any help greatly appreciated!

Luke.

Anyone have any ideas?

I have since found out that the sample application will work on another computer but not my development one (and most of my clients sites').

Thanks Julian,

Seems if I use WPViewPDF1.pas and call:

WPViewPDFLoadDLL('wPDFView02.dll');
wpview_pdfMakeJPEG(....);

it works fine.

Thanks for your help.
