Does anyone know of an API to change the desktop resolution and the TaskBar properties? I'm using Delphi 7, but thought this was more an OS specific question than a language specific question.  Extra points (and heartfelt thanks) for sample Delphi code!!  :-)

WinAPI ChangeDisplaySettings is the standard way to do this.
Here is a sample code in a previous question:

Here is another PAQ with a link on how to change screen resolutions in Delphi:
http://www.experts-exchange.com/Programming/Programming_Languages/Delphi/Q_20113291.html

After an exhaustive search of the net and this site, I determined that you cannot change the AutoHide feature of the taskbar via code.  The closest "solution" was to complete hide the taskbar and then show it again when you are done.  This is not recommended however since the taskbar will be gone if your program crashes or the user switches to another application.

Regards,

Olivares gets points for the first screen resolution answer! :-)

(I guess I've got to start searching EE before posting!)

Idle_Mind: I don't mind hiding the tool bar entirely. This is for a utility I'm using here: I'm doing screen recordings at 800x600, but can't stand to edit them at that resolution. I'll take the the risk. Any pointer to code that does that??
