This dialog box appears when you try to debug a DLL for which no executable is specified. Visual Studio can't launch a DLL directly. Instead, Visual Studio launches the specified executable. You can debug the DLL when it's called by the executable.
Executable file name Enter the path name to an executable that calls the DLL you are debugging.
URL where the project can be accessed (ATL Server only) If you are debugging an ATL Server DLL, enter the URL where the project can be found.
Once entered, these settings are stored in the project Property Pages, so you won't need to enter them again for subsequent debugging sessions. If you need to change the settings, you can open the Property Pages and change the values. For more information on specifying an executable for the debugging session, see Debugging DLLs.
