freeze external display

[artuur9]

Hello, 

I often have a beamer connected to my laptop. To freeze the projected image I can use a ‘toggle freeze’ button on the remote of the beamer, but I would like to do it with a shortcut key on my keyboard using quick macros.
I was thinking that three things are needed for this:

• make a screenshot of current screen
  
• set the external display (beamer) to ‘expand’ instead of ‘duplicate’  (preferably not by using the windows shortcut Windows+p because this shows a menu)
  
• move the created screenshot to the second monitor (the beamer in my setup)
  

To ‘unfreeze’ the external display has to be set to ‘duplicate’ again.

Is it possible to do this with quick macros? If so, how?

1. Function CaptureImageOnScreen.
2. run "displayswitch.exe" "/clone" "" "" 0x4000; 2; run "displayswitch.exe" "/extend" "" "" 0x4000
3. Show a dialog and draw the captured bitmap. Maybe you'll find an example in this forum.

Thanks, 

With displayswitch.exe the 'display switch menu' is visible for a second. Is there a way to prevent this?

And how do I get the dialog with the bitmap to show on the second monitor (external display)?
