Hi koji,
could you explain how do you make "capture" of running applications?
I have used StretchBlt to make a copy, but if source window is covered with other windows I will get an image of both windows.

Thank you,
Nesher

Hi Amos,

If you ativate flip (press win+tab) you can see images of running applications in 3D.
To make this, winflip makes image copy of applications windows. My question is how winflip do this.

Thanks,
Nesher

I can't answer this myself (I don't know), but Koji or kHaN should be able to answer this shortly

Hi nesher

Welcome to WinFlip MessageBoard

If you ativate flip (press win+tab) you can see images of running applications in 3D.
To make this, winflip makes image copy of applications windows. My question is how winflip do this.

It's simple.
WinFlip is using the api "PrintWindow" to get the window image.
Refer the URL below.
http://msdn2.microsoft.com/en-us/library/ms535695.aspx

The api sets the image of the target window to the HDC in the parameters.

See also the sample code.(microsoft)

Is this enough answer for your question?

Yes, thank you

Do you know if Vista DWM uses same method?

It seems that PrintWindow gets only window image without menu, contextmenu or any other popups. Is there a solution for this?
