Screenshot taken by the Application is blank on Vista

Hi,

We have a C# application which captures a screenshot of desktop. It works well on windows XP but on vista the screenshot picture is blank. Why so ?? Any solution to this ?

From stackoverflow

• This should go to stackoverflow; the reason is that the UI programming model radically changed between XP and Vista and you'll be able to get some good help over there.

• It may be because of UAC it uses different desktop to display itself.

• Please post code to help you out. I wrote an article about screenshot (VB.net and c#) sometime back.It works fine in XP and Vista. Check it out if interested.

  How are you capturing it? Is the screensize different?
