    I observed that the height of the ComboBox is always the same one (21 pixels), and do not obtain to modify using MoveWindow(), SetWindowPos() or WM_GETMINMAXINFO...

    How to make the ComboBox only with 17 pixels of height, and to remove the edge?

    I use Win32 API...

    Interesting problem. I wouldn't recommend overriding wndproc() for this. I tried it that way and got many wierd errors. Maybe you might have better luck with it. Assuming you are coding in C#, I solved the problem by a simple P/Invoke to user32:

    Code Block

    using System.Runtime.InteropServices;

     

    const Int32 COMBOBOX_HEIGHTCONST = 0X153;

     

    [DllImport("user32.dll")]

    private static extern int SendMessage(IntPtr hwnd, Int32 wMsg, Int32 wParam, Int32 lParam);

     

    private void AdjustComboBoxHeight(ComboBox control, Int32 height)

    {

    SendMessage(control.Handle, COMBOBOX_HEIGHTCONST, -1, height);

    control.Refresh();

    }

     

    P.S I know the colors are messed up. I don't use the default VS colour schemes. I have a dark background.
