Change resolution of a application

Hallo

I would like to know if its possible, to show an application with higher
resolution then it is build for..?

I have an application (using CF 2.0) that is made for 320x240 resolution.
The HW platform has been upgraded and resolution above 320x240 is now
possible.

So, if possible, I would like to change the resolution to something higher.
If its changes to 640x480 then the application occupies the first quarter of
the screen. Which is excpected. But I would like the application to occupie
the complete screen.
But the application is designed for fixed resolution. Changing every little
form/windows with autoscale, font and achor of controls would take very long
time.

So is it possible to "zoom"/Upscale the 320x240 application to another
resolution. with a 3. parts tool/lib?
Possible with some framework classes??

I know the graphic quality would decrease doing this..
