    common controls

    for my own personal use, I'm making a header file that creates some of the more common controls such as buttons, text, etc. This is how I create one of the controls:

    Code:
    HFONT hfDefault;
    HWND current;
    current=CreateWindowEx(0, "BUTTON", caption,WS_CHILD | WS_VISIBLE | BS_PUSHBUTTON,xpos, ypos, length, width, hWnd,NULL,NULL, NULL);
    hfDefault =(HFONT)GetStockObject(DEFAULT_GUI_FONT);
    SendMessage(current, WM_SETFONT, (WPARAM)hfDefault, MAKELPARAM(FALSE, 0));
    but i have a few questions.

    1.)How do you delete the button off the window?
    2.)How would you go about changing the WS_VISIBLE option?
    Environment: OS X, GCC / G++
    Codes: Java, C#, C/C++

    Lightbulb For the WS_VISIBLE...

    To get rid of/get back the WS_VISIBLE, you use SetWindowLong(...), like this:


    SetWindowLong(hwndButton, GWL_STYLE, WS_CHILD);

    to get it back:

    SetWindowLong(hwndButton, GWL_STYLE, WS_CHILD | WS_VISIBLE);


    You will have to use UpdateWindow(hwndOwner); or something like that to update the visibility of the button when you change its style.

    Hide / show the button from view with ShowWindow() .
    DestroyWindow() to kill it compleatly.
