    Buttons in C++

    I have a window with some basic menus. I am looking to add buttons to it. Would someone kindly be able to give some simple steps or point me in the direction of a straight forward tutorial?

    In case your interested:

    Here's the code that is used for the window:

    Header File:
    Code:
    #define ID_FILE_NEW           100
    #define ID_FILE_OPEN          101
    #define ID_FILE_SAVE          102
    #define ID_FILE_EXIT          103
    #define ID_DO_SOMETHING       104
    #define ID_DO_SOMETHING_ELSE  105
    #define ID_HELP_ABOUT         106
    Resource File:
    Code:
    #include "tutorial.h"
    
    ID_MENU MENU DISCARDABLE 
    BEGIN
        POPUP "&File"
        BEGIN
            MENUITEM "&New",                        ID_FILE_NEW
            MENUITEM "&Open",                       ID_FILE_OPEN
            MENUITEM "&Save",                       ID_FILE_SAVE
            MENUITEM SEPARATOR
            MENUITEM "E&xit",                       ID_FILE_EXIT
        END
        POPUP "&View"
        BEGIN
            MENUITEM "&Instructions for use",       ID_DO_SOMETHING
            MENUITEM "Sample Video",                ID_DO_SOMETHING_ELSE
        END
        POPUP "&Help"
        BEGIN
            MENUITEM "&About GST",                  ID_HELP_ABOUT
        END
    END

    PS- Quick Question:

    Is there a limit to how many of these you can use in a program?
    I got this message when I tried using two resources. Might have been another and may not be linked but I'm sure.

    Moved to windows board.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Like you normally create windows, but instead of registering a window class name you use the text "BUTTON". I believe you have to state WS_CHILD as a flag too, and set the parent argument to the window the button should be in.

    Thanks for the reply.

    Is the line where I need to insert "BUTTON"?

    Code:
    WndClass.lpszClassName = sClassName;
