An application sends a ZIM_DISPLAYIMAGE to cause the ZeeImage control to instantly display the image that was previously loaded into the specified slot.
ZIM_DISPLAYIMAGE
wParam = (WPARAM)(int) iSlot; //slot or index of the image control
lParam = (LPARAM) 0; //Not Used
This message does not return a value.
SendMessage(himage,ZIM_DISPLAYIMAGE,3,0);
The slot indicated in wParam will cause the image previously loaded into that slot to be instantly displayed in the ZeeImage control.
If the slot referenced does not have an image loaded into it, the client area of the ZeeImage control will be blank.
