I am using window regions to define non-rectangular shapes, but nearly everyone objects to the jagged aliasing this causes, because pixels can only be either fully opaque or fully transparent. I've come up with a solution to this using layered windows, b...

I have an ActiveX control that gets placed in an IE browser container. The control creates another dialog window that has WS_POPUP and WS_LAYERED properties enabled in order to be able to use SetLayeredWindowAttributes(...) function to accomplish color keyed transparency and alpha blending on top of the control. Because the WS_LAYERE...

Thanks ahead of time! ...

Hi, Many application are using multi-top-level windows. One of the good example is for layered window: if application need a real transparent control, the best way under MS windows is to use layered window(win32 programming, no WPF). But Layered Window must be top-level window. The problem happens during you restore a minimized applicat...
