Re: Passing single service in command line

It does help but unfortunately commenting out that line will cause none of the command line functions to execute - it just terminates. So not good for the app if it cant actually control anything.

Look at the argc variable passed to ParseCommandLine().

What is it in particular that im looking at. The variable itslef has to exist as a count for the number of arguments passed to the command line, right?

The argc parameter. I'm assuming it's the same argc that was passed to the main() function.

most of the MFC objects internally uses local thread storage extensively.
so they are bound to their owner thread, and not supposed to be shared with other threads.
this is why MFC has thread affinity.

It's not a bug, it's an undocumented feature.

To have thread affinity means to be "bound to the thread". Therefore the object can only be used safely from that thread.

In the case of MFC, some objects are bound to threads through MFCs use of Thread Local Storage. Attempting to use the object in a thread other than the thread it is bound to will result in errors since the thread local storage data is not present.

Hope that helps?

CreateService is used to create a service object as well as add the service to the SCM database.

SC_HANDLE CreateService(
   SC_HANDLE hSCManager,
   LPCTSTR lpServiceName,
   LPCTSTR lpDisplayName,
   DWORD dwDesiredAccess,
   DWORD dwServiceType,
   DWORD dwStartType,
   DWORD dwErrorControl,
   LPCTSTR lpBinaryPathName,
   LPCTSTR lpLoadOrderGroup,
   LPDWORD lpdwTagId,
   LPCTSTR lpDependencies,

Have you looked in shlobj.h to see what other constraints might be keeping IActiveDesktop from being defined? You've indicated that _WIN32_WINNT has been defined, but was it defined before shlobj.h was included?

Sure they can. Have you not been seeing them in other's posts?
