Adding a Window Property (Windows CE 5.0)

Send Feedback

To assign a window property and a string identifier associated with that property to a window, call the SetProp function.

The following code example shows how to load an icon and a cursor and then allocate memory for a buffer. The example then uses the SetProp function to assign the resulting icon, cursor, and memory handles as window properties for the window identified by the application-defined hwndSubclass variable. The application uses the strings PROP_ICON, PROP_CURSOR, and PROP_BUFFER to identify the window properties.

#define BUFFER 4096

HINSTANCE hinst;       // Handle to current instance 
HWND hwndSubclass;     // Handle to a subclassed window 
HANDLE hIcon, hCursor;
TCHAR *lpMem;
TCHAR tchPath[] = TEXT("\\samples\\winprop.c"); 

// Load resources.

hIcon = LoadIcon(hinst, MAKEINTRESOURCE(400)); 
hCursor = LoadCursor(hinst, MAKEINTRESOURCE(220)); 

// Allocate and fill a memory buffer.

lpMem = (TCHAR*) LocalAlloc(LMEM_ZEROINT, BUFFER); 
if (lpMem)
{
   lstrcpy(lpMem, tchPath); 

   // Set the window properties for hwndSubclass. 

   SetProp(hwndSubclass, TEXT("PROP_ICON"), hIcon); 
   SetProp(hwndSubclass, TEXT("PROP_CURSOR"), hCursor); 
   SetProp(hwndSubclass, TEXT("PROP_BUFFER"), lpMem); 
}
else
{
   // Appropriate error handling code
}
