Why is When I changed my windows display size from 125% to 150% , My program's forms which i made it with Visual C# will be so big and nasty : If there is a way to make these forms and its' controls stay of its' sizes without any changing whether i changed windows display size or not, and please don't tell me to use tabular panel or any other container or layout because I'm not complaining from forms or controls location , so please if you have an idea to solve this problem please answer me .
