Opacity and Trancparency Problem

[ramtin]

When I have a form that is shaped by a picture , and also tranceparent Color (red) , if I set Opacity less than 100% , the tranceparent color dose not take effect any more , and the form shows that , any idea?

 

Thanks

It is likely that this is a video card issue, because this does not happen on my computer. The only solution I can suggest is to use an actual Form Region (you can set the Region property of the form) to shape the form, rather than just using the TransparancyKey property, which I believe uses another method (layered windows, perhaps).

 

Look at the MSDN for the System.Drawing.Region class.

The problem is on background picture

 

Thank you , but the real problem is , when you transparent one of the background image colors , after you set opacity of the form less than 100 , that color is not transparent any more

I know. I'm suggesting that rather than letting the TransparencyKey property handle the shaping of the form, you use Regions to shape it manually. You shouldn't have any problems them.
