System.Drawing.Font fntT = new System.Drawing.Font("Courier New",10);
surPrint.FontHandle = fntT.ToHfont();
surPrint.ForeColor = Color.White;
Hi, the above code is exactly what i use to set the font handle of the surface. This code exsists in the main loop, so for every frame this is executes.
When i run the program it works fine for about a minute or two, until an exception occurs:
An unhandled exception of type System.ArgumentNullException occurred in microsoft.directx.directdraw.dll
Additional information: Value cannot be null.
This is very annoying. Nothing changes in the loop... the same code is executed. As I said before the code works for about 2 minutes then throws this exception.
I commented out the lines dealing with the font handle
System.Drawing.Font fntT = new System.Drawing.Font("Courier New",10);
surPrint.FontHandle = fntT.ToHfont();
And it runs fine without throwing any exceptions at any time.
So Im guessing it has something to do with the font handle.
But it works fine for 2 mins 
.
Btw, because of what I have planned, I need to set the font handle every time it loops. So setting it before the loop begins is not an option for me. I hope this is not an internal error that is out of my reach, that would suck.
Any ideas / suggestions
thanx in advanced.
