I just begin to work on windows mobile application. after I nearly done this work, I tested my program on a phone with windows mobile 6.5. problem is the background image of dialog did not cover the whole as it did when I run the program on computer.

I have to make sure that background image of dialog will display correctly on various size of mobile screen with various resolution . how can I achieve that ?
should I prepare different image for each mobile screen? what about resolution ? what factors should I consider and how ?

I am using C++ with visual studio 2008 .
the well tested idea and example would be best..

anyone tell me how to do it?

Solution 1

The problem is probably that the actual size (in pixel) of the dialog depends on the device and on the fonts configured for it.

You sould not diplay a "fixed size" elements on an unknown device. You should insted get rid of the effective size of your dialog, and scale the bitmap acordingly.
