Background: trying to grab some resources from a file. Take a look below, I need to know how to setup a callback function:

[DllImport("kernel32")]
private extern static long EnumResourceTypes(long hModule, long lpEnumFunc, long lParam);
[DllImport("kernel32")]
private extern static long EnumResTypeProc(long hModule, string lpszType, long lParam);

m_hMod = LoadLibraryEx(Filename, 0, LOAD_LIBRARY_AS_DATAFILE);
EnumResourceTypes(hModule, EnumResTypeProc(),0);

What do I need to do to get EnumResourceTypes to call the second variable as a callback function?

You don't need to import EnumResTypeProc. You should write it yourself and pass it's address to EnumResourceTypes.

Right EnumResourceTypes definition is:

[DllImport("kernel32")]
private extern static long EnumResourceTypes(IntPtr hModule, EnumResTypeProc callback, long lParam);

EnumResourceTypes is your delegate:

delegate bool EnumResourceTypes(
   IntPtr hModule,
   [MarshalAs(UnmanagedType.LPTStr)]
   string lpszType,
   long lParam);
