Beth,
First off, you are not allowed to display UI elements in COM DLLs. You can if you create COM EXEs.

Second, I received an error when compiling this and added
EXTERNAL ARRAY pdisplayarray
just below the parameters statement.

Even with all of this, the test program you originally posted worked up until the UI display. Make sure the DLL exists. Use RegEdit or RegEdt32 to check your registry for the DLL entry. If the DLL exists but the registry entries don't, use Regsvr32 to register your DLL:

regsvr32 Testing.Dll

HTH.
