screensettings
Hey I wrote a program with a setting of 1024x640 or so.
I noticed that this is not very common and that my programforms controlls and everything else is way to big in a lower setting.
is there a way to change the setting for my programm without changing windows settings.

As suggested by igfp its good if you adjust your form and controls to support lowest possible resolution so that it will atleast display everything on the form(if not in the most presentable manner)
However if u still want to change the settings here is an extract from api guide by http://www.allapi.net that helps you to change the settings.

sorry that all doesn't help me.
my programm is allready so complicated and set up so that I would be easyer to write a new programm then to change it.
Which is the api to change the windows settings? is there a way to insure that the old settings are restored when the programm unexpecetedly quits?
THANKS

It's better to make a smaller one that fits other screens or change the windows settings. You should be able to do this by changing the forms.
