The GDI32.dll does not contain a GradientFill() function. The actual entry point is GdiGradientFill(). That's why the 'EntryPoint' attribute is present.

Note that there are two entrypoints to GetTempPath in kernel32.dll called "GetTempPathA" and "GetTempPathW". So if you want to use GetTempPath you have to set the EntryPoint on the DllImport-Attribute as follows (C#):
