Window Style Bits

[agent]

I'd like to remove to Thickboarder, Min and max buttons, and the sysmenu from another window. I've already worked out the code to get the hwnd and the current style flags.

So far, I've tried most of the logic functions with the bits to try to turn them off.

the code looks something like this:

    Dim newstyle As Long
    
    oldstyle = GetWindowLong(hwnd&, GWL_STYLE)
    newstyle = oldstyle Or (WS_CAPTION Or WS_MAXIMIZEBOX Or WS_MINIMIZEBOX Or WS_SYSMENU Or WS_THICKFRAME)
    SetWindowLong hwnd&, GWL_STYLE, newstyle

I've tried "or not", "and", "or", "and not", "-", "+", and "xor"

None seem to have any effect.
