Gets the bitmap list attached to the specified cell.
Parameter |
Description |
hCellWnd |
A handle to the window that represents the cell on which the function's effect will be applied. |
phBitmapList |
Pointer to the variable to be updated with the cell's bitmap list. |
uFlags |
Reserved for future use. Pass 0. |
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
If the cell at the specified index has no image, phBitmapList will be NULL.
