An application sends a ZGM_SAVEGRID message to save a ZeeGrid from to a file. The saved file can then be loaded at a later time with the ZGM_LOADGRID message.
ZGM_SAVEGRID
wParam = 0; //not used; must be zero
lParam = (LPARAM) lpszString; //address of string specifying the filename to save
This message does not return a value.
