Hi All,

I want to hide the minimize and maximize buttons on an MDI window. I have found a Microsoft article which seems to be exactly what I want to achieve here:

However, I am not sure how to convert the VB code to VFP. I understand the API calls themselves, that is straight forward enough. But I do not understand what the constant declarations are as in:

    Const WS_MINIMIZEBOX = &H20000
    Const WS_MAXIMIZEBOX = &H10000

... or how to use them in calculating a new value for "L" as in:

         L = GetWindowLong(Me.hWnd, GWL_STYLE)  
         L = L And Not (WS_MINIMIZEBOX)
         L = L And Not (WS_MAXIMIZEBOX)
         L = SetWindowLong(Me.hWnd, GWL_STYLE, L)

What is &H20000 and &H10000 ? How can I do this in VFP?

Any help appreciated.
