Thanks Uwe and Daniel,

I compiled this example, but it does not do anything at all other than blinking the screen once each time I press the button.

By the way I unplugged the extra monitors and only left one working, and still does not do anything... (this is weird, since I realize that it is Windows API that is asked to do the changes)

Daniel, I am just providing feedback, I do not use this functions, so do not set It's priority level too high, since it is already working for Uwe; I know you are working in a lot of kool and usefull things for FiveWin!!!

I still have a Question about the Position of Desktop-Icons.

After changing the Screen-resolution it is possible, that Icons are displayed on different Places.
For that Reason, there are some Freeware-prog*s available ( external ) to save and restore Icon-positions.
Is it maybe possible, to do this from inside a FWH-application as well ?
It would make Daniel's Solution complete.

A standalone Application to save / restore the Desktop-icon-positions => Download :

I still found another one. Maybe a better Solution.
Autorestore, in case of a changed Screen-resolution ( saving to a File ).



Best regards

This is great!
I downloaded a command line desktop restor from http://www.midiox.com/desktoprestore.htm
and used the following at the start
Code (fw): Select all Collapse
   IF nScrwidth <> 1024 .and. nScrheight <> 768
      // Copyright   2010 by Jamie O'Connell <!-- m --><a class="postlink" href="http://www.midiox.com">http://www.midiox.com</a><!-- m -->
      WaitRun(cINIPath+'DesktopCmd save /y' )
      CHANGEDISLPAYRESOLUTION( 1024, 768 )
   ENDIF

and the following trigered by closing the window 'VALID' (passing nScrwidth, nScrheight)
Code (fw): Select all Collapse
   IF nScrwidth <> 1024 .and. nScrheight <> 768
        CHANGEDISLPAYRESOLUTION( nScrwidth, nScrheight )
        WaitRun(cINIPath+'DesktopCmd restore /y' )
   ENDIF

This is its simplest form.
Can be optimised in case the resolution gets changed back by the user while still in your program.
Thanks Daniel! :-)

Bayron have you got the resolution to change on one? or two screens?

Jonathan,

Thank You very much.
This Solution works fine for me.
Do You know, if the existing Resolution is written to a File or Registry ?
With 2 Monitors, I couldn't test.

Best Regards

Reg => HKEY_CURRENT_USER\Software\JOConnell\DeskTop
You can define a registry storage name too.
More info in the rtf info in the download.
I have just been looking at some of Jamie oConnell's code on the website - undocumented windows - clever!

I dont have 2 screens. I will test at a customer site next week with 2 screens.
Maybe dependant upon screen driver, resolutions.
It would be nice to have a command to return the resolutions available?
Bayron have you got any results with 2 screens?

Jonathan
