In converting routines that have worked in VS6 and .NET to VS8, the following item failed to work.

Purpose: To enumerate routines in a DLL

Problem: The ImageDirectoryEntryToDataEx call fails for the V8 library but works for the V6 library. LoadLibrary returns a handle for both.

Question: Does A) VS8 create a DLL that cannot be processed with this call or
B) is this a problem with ImageDirectoryEntryToDataEx or
C) Did install not put a correct DbgHelp.dll or ImageHelp.dll in the appropriate path?

Code Section:

case 0:
DLLHandle = LoadLibrary("F:\\Temp\\V6\\filter1.dll" );
break;
case 1:
DLLHandle = LoadLibrary("F:\\Temp\\V8\\filter1.dll" );
break;
