Thread: runtime style changing

I can add styles to a dialog runtime with GWL_STYLE,GetWindowLong so,

Code:

static DWORD oldStyle;

oldStle=GetWindowLong(hwnd,GWL_STYLE);
                               SetWindowLong(hwnd,GWL_STYLE,oldStyle|WS_MINIMIZEB
                              OX);

but I can not remove styles with using ! operator prior to styles. For this instance,

Code:

oldStle=GetWindowLong(hwnd,GWL_STYLE);
                               SetWindowLong(hwnd,GWL_STYLE,oldStyle & !WS_MINIMIZEBOX);

what is the true way? I'm studying on a Propert Sheet dialog.

Try ~ instead.

Code:

oldStle=GetWindowLong(hwnd,GWL_STYLE);
                               SetWindowLong(hwnd,GWL_STYLE,oldStyle & ~WS_MINIMIZEBOX);

Thank you very much shaik786. Btw, for Hammer, yep I tried it before...
