WPDFView under windows 98

Postby Purgie » Tue Nov 25, 2003 11:04 am

Hello, everytime i try to run an application under W98 se i get the following message :


Windowclass WPCUBED_PDFVIEW_01 cannot be found. Strange because i in my code i put the following lines :

- WPPDFViewerStart('MyName', 'MYCODE', MYNUMBER);
- WPViewPDFDLLNAME := 'wPDFView01.dll';

I also put the DLL on the good directory.

What am i doing wrong..

Greetings, Frank

Currently WPViewPDF is not released for Windows 98. Sorry about that.

I am now occassionally having users report this same error on Windows 10 systems.

"Windowclass WPCUBED_PDFVIEW_01 cannot be found!"

The file is present and works for most users.

This can only happen if the DLL was not loaded at the time the CreateWnd takes place. Maybe it was unloaded?

We don't do anything to unload it and this only happens for a few of our users. Any idea what would trigger this?

Hi,

Please make sure the WPViewPDF DLL is never unloaded while the application runs.
This could cause such a problem.

According to the title of the thread "WPDFView under windows 98" - I would not recommend to use it undoer Windows 98.
