An application sends a ZGM_GETSIZEOFGRID to get the size of the data structure (in bytes) of a ZeeGrid.
ZGM_GETSIZEOFGRID wParam = 0; //not used; must be zero lParam = 0; //not used; must be zero
The size (in bytes) of the ZeeGrid data structure.
This is the ZeeGrid overhead for every ZeeGrid window in your application. It is this value, plus the size of the zeegrid cell * the number of cells allocated that determines the minimum amount of memory allocated to a particular ZeeGrid. This does not include the memory required to hold the text strings displayed in the cells.
