Remove window styles

[ragdog]

Hello

I have a window style with WS_THICKFRAME and WS_WS_SIZEBOX
Now wish i remove via code this styles

Code Select Expand

       invoke  GetWindowLong, hWnd, GWL_STYLE 
       mov  ebx,WS_SIZEBOX
       not ebx
   and eax,ebx
       invoke  SetWindowLong, hWnd, GWL_STYLE, eax 

       xor     eax,eax
      invoke  SetWindowPos,hWnd,eax,eax,eax,eax,eax,SWP_NOZORDER or SWP_NOMOVE or SWP_NOSIZE or SWP_FRAMECHANGED or SWP_SHOWWINDOW


Must i use SetwindowPos or gives a better Api for it?


If I do not use SetWindowPos and I move the window  have a white frame on the dialog :(

Ok i can change it in the resource but i wish it with code

What happens if you just set the window style completely with SetWindowLong() then issue a repaint ?

if you change the frame, you should call SetWindowPos

If you have changed certain window data using SetWindowLong, you must call
SetWindowPos for the changes to take effect. Use the following combination for
uFlags: SWP_NOMOVE | SWP_NOSIZE | SWP_NOZORDER | SWP_FRAMECHANGED.
