    Smile Help resizing client area

    Greetings! I am making a paint program, and I need to know how to resize the CLIENT AREA of the window, not the window itself. I am trying to get the client area to be 64x64, but have had no luck. Please guide me in the right direction! I thought sending a WM_SIZE message would do the trick, but it didn't. Any help would be greatly apperciated! ^_^

    The quick solution would be to make the area you paint in a child window whose size you can control when you create, or whatever. If you look into thee window styles you'll see you can create windows with no borders, aka just a client area. Make the icon null, and window type WS_CHILDWINDOW|WS_VISIBLE. This should take care of your problem.

    You could call

    AdjustWindowRect() //gets window rect from client rect

    and then use the values in

    SetWindowPos() or MoveWindow()//moves and/or sizes windows

    Thanks for taking the time to post replys. I apperciate both of your solutions. I had little trouble implimenting the first solution, but, I would really like an example of the second one if it wouldn't be too much trouble.

    Post what you have tried and I will correct it. Will not just write the code for you.

    Send in a *RECT (&Rect) set to 0 and the size needed (0,0,64,64) to AdjustWindowRect().
    GetWindowLong() will get the styles, look up the flag probably GWL_STYLE.
    Set the BOOL to true if the window has a menu.

    On a successful return the Rect will contain the dimensions of the window rect.

    Then just resize the window.
