    Dear bbeeusa:

    Please look here:

    In ZAPRO, go to Program Control panel, Programs tab, and find entry, Run a DLL as an App. Click on it and you can see the Entry Detail at the bottom. rundll32.exe is a Windows system file.

    Hope this helps.

    Rundll32 loads and runs 32-bit DLLs. It's located in the folder C:\Windows\System32. In other cases, rundll32.exe may be a virus, spyware, trojan or worm! Rundll performs the following steps:
    1. It parses the command line.
    2. It loads the specified DLL via LoadLibrary().
    3. It obtains the address of the <entrypoint> function via GetProcAddress().
    4. It calls the <entrypoint> function, passing the command line tail which is the <optional arguments>.
    5. When the <entrypoint> function returns, Rundll.exe unloads the DLL and exits.
