I wish to derive the row height for ListBoxes however so far I have not succeeded. I have been using SendMessage as follows...



In Borland window.h file I see #define LB_GETITEMHEIGHT     (WM_USER+34)



If WM_USER is 1024 then I assume that LB_GETITEMHEIGHT is 1058



My code is trial 





hWnd=Get_Property(BubCtrl,"HANDLE")

RowHeight=SendMessage(hWnd,1058,1,0)	



hWnd returns an integer that looks reasonable for an hWnd however RowHeight is always returned as 0



Has anyone else succeeded in getting the row height for a listbox?



Thanks in advance
