#302 MSG_WM_WTSSESSION_CHANGE should crack lParam as session Id

[klaus triendl]

MSG_WM_WTSSESSION_CHANGE cracks lParam as PWTSSESSION_NOTIFICATION, which is only used in the service control handler callback function. The correct type to cast to is simply a DWORD.

[klaus triendl]

... or ULONG

[Nenad Stefanovic]

It is probably DWORD, at least according to the WTS_SESSION_INFO structure

The confusion here was because of WTSSESSION_NOTIFICATION struct defined in WinUser.h

Fixed now.

Thanks and already in use :)

Not DWORD but LPARAM. (DWORD - unsigned but LPARAM - signed)
Because LPARAM is declared as

#typedef LONG_PTR LPARAM;

And LONG_PTR as

#if defined (_WIN64)
     typedef __int64 LONG_PTR;
#else
     typedef long LONG_PTR;
#endif

There will be problems in 64-bit system

[Nenad Stefanovic]

I don't think that will be a problem, WPARAM and LPARAM can be anything

[Anonymous]

It can be anything if it is passed as a pointer, and here is the value.

[Nenad Stefanovic]

Why would this be different than WM_ACTIVATEAPP? Look for it in windowsx.h

[Anonymous]

Sorry. You right.

typedef unsigned long DWORD;

and

typedef long LONG_PTR;

The same.
