Thanks for all your contributions.
I've downloaded the service pack 6 and tried to add Microsoft Windows Common Controls 2.60, but I'm getting the error: "Name conflicts with existing project, object or module"
I'm unable to understand it.
My project consists of many forms, modules and reports. I've used DTPicker in four of my forms. I've started developing the project in another old system and now I want to continue it in my present system. I'm facing errors while loading as the DTPicker is not available.
