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
