    Control Classes

    I'm making windows programs in Visual C++ and I'm only using the API. I had a couple questions about creating controls on the windows. I can make the controls, but I found it space consuming to use the code over and over again for each thing. Then I decided to make an include file with functions(it has been successful). But now someone has told me to use classes to make the controls. How can I make classes for controls used on a window? Should I make a base class for all controls, and then use inheritance to make a class for each control? I don't even know how to do that!!!! Help?!

    go and read some tutorials on the web.

    www.cplusplus.com is a good place to start.... if you don't know about classes, pointers and polymorphism then you're going to struggle.. so read up and give it a go.

    control classes

    Why have you chose not use a windows programming library such as owl or MFC? These libraries are rich in control classes. There are edit controls, list controls, button controls and many others. The best part is that they have been tested and are commonly used.

    Stick with the API. And C. Stick with C. It is what was meant to be

    Well...you could probable try this...

    Code:
    class MyControl
    {
         public: 
                 HWND hwnd;
                 void Create(/*params*/)
                 {
                         hwnd = CreateWindow(/*params*/);
                 }
    }
    ....
    
    MyControl Edit1 = new MyControl();
    MyControl.Create(/*params*/);
    then if you needed the HWND for some reason you could always use MyControl.hwnd

    but then again I'm not sure if that's right...I've never used C++ before (just C) I'm getting all that from what I know about OO in C#

    Yes, but I can't see how that would make programming Windows easier. The parameters to the member function will still have to be extensive to specify for the "insides" of the member function. It will just be another class name to remember

    C++ allows default arguments. Which can be useful for functions with lots of arguments that are nearly always the same every time you use the function.
