ActiveBrowser.Window.GetBitmap BLACK SCREEN

[Oleg]

Hello. I am using next function ActiveBrowser.Window.GetBitmap to make screenshot of my activeBrowser's rectangle. I faced with the black screen as output screenshot. I attached the VS 2008 solution. Please help me to resolve it.

P.S. Test steps:
1. Open browser
2. Load google page
3. Input "wikipedia" in the search field
4. Choose wikipedia from the search results to open wikipedia.org
5. MAKE SCREENSHOT which is placed to C:\

When I open screenshot.png I see only BLACK SCREEN

Hello Oleg,

I assume your screen is not locked or the screen saver is not running when you experience this problem? We have seen this on rare occasions and so far it's always been machine dependent  We don't have a solution to this problem except to use a different machine, or video card/driver.

Thanks for reply. I'll try another machine

Seems that the problem was found. It is not in machine's hardware(video adapter). I changed video adapter which didn't solve the problem. This happens only on XP. If I run test on Windows 7 the problem is absent. Was tested on 3 XPs and 3 Win7 different machines.

Hi Oleg,

That is very good information! Thank you very much for the update. I'm going to forward this info to our QA engineer to see if he can reproduce the same problem as you describe.

Best wishes,
