I need to get the dots per inch that a Windows form uses on the client. From what I have found out so far, I believe that I have to use GetWindowDC using P/Invoke. I am programming in C# but I know VB.NET and could probably work w that too. I have zero experience with C or C+ or C++
The related examples I have found start with stuff like the following, which I grasp, but cannot figure out how to use.
public static extern IntPtr GetDC(Int32 ptr);
