    Child window/OpenGl

    I can't seem to get a child window to show up when I draw using opengl in the same application. I can tell it is there because when I click and drag where it should be, I can see the outline of it, but it is not visible. Is there any way to do this?

    At the moment I'm defining the dialog in a resource file like this:
    Code:
    IDD_DIALOGLEFT DIALOG DISCARDABLE 0, 0, 100, 100
    
    STYLE WS_CHILD| WS_VISIBLE | WS_CAPTION 
    EXSTYLE WS_EX_TOOLWINDOW    
    //...
    And calling CreateDialog:
    Code:
    CreateDialog(hInstance,MAKEINTRESOURCE(IDD_DIALOGLEFT),hWnd,NULL);

    I know them not: not therefore am I short
    Of knowing what I ought."

    Zip up a minimal project that demonstrates the issue....it'll get fixed faster that way.

    Ah never mind I added WS_CLIPCHILDREN to the parent window style and now it shows up...

    Ok now I added a dropdown list to the window. I don't have very much windows experience as you can probably tell, and when you click on the arrow to display the list it doesn't display them...instead you have to scroll through the list with the arrow keys. Do you have to manually tell it to drop down? I tried:
    Code:
         SendMessage(cHwnd, CB_SHOWDROPDOWN, TRUE, 0);
    But it does nothing. I'll attach an example program

    Edit: There may be some OpenGL variables left in there because I originally thought it was a problem using OpenGL. You should just be able to ignore any of that if I accidentally left it in there.

    If I remember correctly the height of a combo box includes the drop down portion.

    Thanks! I can't believe it was so simple! Ah well, at least I'm learning :P
