SHACTIVATEINFO (Windows Embedded CE 6.0)
1/6/2010
This structure sets members for the SHHandleWMActivate function.
Syntax
typedef struct {
DWORD cbSize.;
HWND hwndLastFocus.;
UINT fSipUp.:1;
UINT fSipOnDeactivation. :1;
UINT fActive :1;
UINT fReserved :29;
} SHACTIVATEINFO, *PSHACTIVATEINFO;
Members
- cbSize
Size of SHACTIVATEINFO structure.
- hwndLastFocus
Handle to the window that had focus when losing activation. Focus will be restored to this window when gaining activation.
- fSipUp
Current state of the input panel.
- fSipOnDeactivation
State of the input panel when losing activation.
- fActive
Set this member to TRUE if the window is active and FALSE if it is inactive.
- fReserved
Reserved for future use; set to 0.
Remarks
The SHACTIVATEINFO structure must be zero-initialized before calling the SHHandleWMActivate function the first time. In addition, the cbSize member should be set to the size of the variable of type SHACTIVATEINFO. For example,
static SHACTIVATEINFO shellactinfo;
// Initialize the shell activate info structure
// before calling SHHandleWMActivate function
memset(&shellactinfo, 0, sizeof (shellactinfo));
shellactinfo.cbSize = sizeof (shellactinfo);
Typically, this is done during WM_CREATE or WM_INITDIALOG processing.
Note
Make sure to zero-initialize SHACTIVATEINFO as early as possible within WM_CREATE or WM_INITDIALOG to avoid a runtime error.
