An application sends a ZGM_GETCOLUMNORDER message to programmatically retrieve the ZeeGrid column dispay order. lParam is a pointer to an array of integers. wParam is the number of elements in the array pointed to by lParam.
ZGM_GETCOLUMNORDER wParam = (WPARAM)(int) iElements; //number of elements in the array in lParam lParam = (LPARAM) lpiArray; //array of integers
This message does not return a value.
Before using this message, the programmer should get the number of columns with ZGM_GETCOLS. An array of integers should be created with this number of elements. The number of elements in the array must be specified in wParam and be equal to the number of columns in the ZeeGrid.
