CProgressCtrl

[wave]

I have developed a Microsoft C 6.0 Win 32 DLL without class definition. The DLL is to be called by VB program under Win 98. The DLL has shared segment with system hook implementation.

Can I call CProgressCtrl class in my DLL? If yes, what steps shall I take? If no, is there any alternative for displaying progress?

Thanks.

You can't use a real C++ class from VB. Either you write a function-based interface to the class or you write an ActiveX control.

This is exactly my target approach.

The VB program calls a function implemented in the C DLL which takes a long execution time. My professor ask me to display progress during execution but my function is a pure C without class and my program is a Win 32 DLL.

Is there any solution?

Thanks a lot

Sure. Use pure WinAPI for the progress bar. Learn about common controls, the progress control is one of them.

Thanks for your advice.

Wonder if there is any sample program to learn from?

Thank you.
