An application sends a ZGM_GETSIZEOFCELL to get the size of the data structure (in bytes) of a ZeeGrid cell.
wParam = 0; //not used; must be zero
lParam = 0; //not used; must be zero
The size (in bytes) of the ZeeGrid cell data structure.
This value multiplied by the number of cells allocated plus the size of the grid is the total number of bytes of memory required for the ZeeGrid. This does not include the memory required for the actual display contents (the text) of the cells.
