4. Under Configuration Properties, expand the node next to "C + +" and select "General". Make sure that debug Information format is set to program database/ZI (instead of "/zi").

5. Under Configuration Properties, select "C + +" and select "code Generation". Make sure that the Run-time library is set to one of the multithreaded debug DLLs (/MDD) or multithreaded DLLs (/MD).

#using <mscorlib.dll>

#using "DownloaFiles.dll"//Replace with required DLL file

using namespace System;

Using namespace admessage_test;//to the namespace used by classes in the DLL

Add #pragma managed before the DLL function calls the code
