need a help in vb6 to handle third party party software using dll files
or tell me how my dll files can attached to third party software while running
All you need to do is to reference the .Dll file under references in your application. You then have access to the control.
Click on Project on your toolbar, select References and search for the .Dll file from there. If you can not see the dll in the list, click on 'Browse' and select from there. It will take you to the System files automatically.
Once you compile your application, the dll file will be included in your .Cab file.
