GUI Form Exception when running C# form on Mono
-
Hey All, I am trying to run a C# GUI Form on Fedora 8 using mono. If I run console applications, everything runs fine, but if I try to run a simple GUI application, I get the following exception (by the way, I didn't have to install mono, since it came with Fedora 8, but my guess is I am missing a graphic component needed to run GUI forms):

As far as I can see, you're missing a DLL called gdiplus.dll.

Found this article which seemed to explain at least one of the errors above: http://www.mono-project.com/DllNotFoundException[^] It didn't fix my problem though, because even though there was a GDI+ library at "/usr/lib", it was called "libgdiplus.so.0" and "libgdiplus.so.0.0.0" (wrong folder and wrong name). I tried to reinstall the GDI+ library, but the machine froze and I had to reboot to get it back. :(

Finally found the solution to my problem. There was nothing wrong with GDI+, Mono or any other package on the system. The problem was Fedora 8s new Security System!! If I log in as root (not a good practice) and run the same application the GUI Application executes fine. So I think their new security system needs some more work. :laugh: Thank you everyone who tried to help.
