Compiling custom Qt3 Widgets Gives warning in VC++6 Compiler

I have attached the widgets that can be used for Database Operations

Compiling it in linux Gave me no warning. But it is giving warnings when I tried to compile with VC++ 6 Compiler

Could you please explain how to eliminate it.

If useful you may use this in your applications. Or atleast use it for learning purpose

What warnings?

The more work your question requires, the less people will bother to look into it. You can see those warnings without any additional work, while others must download, uncompress and compile your sources (not mentioning booting the windows).
