On our desktop machines we have a standard build but with various changes per department at login, and sms etc..
What I am wanting to do is dynamically change the bitmap (desktop background) to include a build version number and department name at the bottom... can this be done???

David

Hi David,
Take a look at: http://www.sysinternals.com/ntw2k/freeware/bginfo.shtml
With a bit of tweaking, should give you what you need.
Cheers

In VB...
Capture the form...
Public Function CaptureWindow(ByVal hWndSrc As Long, ByVal Client As Boolean, ByVal LeftSrc As Long, ByVal TopSrc As Long, ByVal WidthSrc As Long, ByVal HeightSrc As Long) As Picture
Save it...
SavePicture Picture1.Picture, "c:\windows\bitmap.bmp"

David,
Do you mean programatically?
Short description...
There is something called a device context - a representation of a drawing surface. Create a bitmap with the Win32API call, CreateCompatibleBitmap. Create a memory DC and select the bitmap into it. Draw text retrieved from a SYSTEM_INFO structure into the DC. Save to file.

MrDeference, thats exactly what I mean..
I like the app and its almost perfect, but im one of these people thats never happy.. and like to modify things... like i want it to choose which background to use ie 800x600 , 1024x768 etc.. without having to stretch it..
And would rather write the app internally than use a third party tool... (even though I have just rolled that out..)

Good luck.
It should be quite simple to do, particularly if you use MFC, as all the required APIs are wrapped up in easy to use classes.
If you get stuck give us a shout...
