SUMMARY

You can use the RUNDLL32 application that is provided with Windows NT and Windows 95 to debug Control Panel applets. Use the following debug settings (set by selecting Build/Settings in Visual C++ version 4.x, or by selecting Project/Settings in Visual C++ version 2.x and 5.0): 

   Executable For Debug Session: C:\winnt\system32\rundll32.exe

                                            - or -

                                 C:\windows\rundll32.exe
   Working Directory:
   Program Arguments: shell32.dll,Control_RunDLL [path and name of
                                                  CPL file]
   Remote Executable Path and File Name:
The two choices for "Executable For Debug Session" are for both Windows NT and Windows 95. You must type in the name "Control_RunDLL" exactly, and you must use the full path and name of the Control Panel applet (.CPL file). You do not have to provide information for "Working Directory" and "Remote Executable Path and File Name."
