ListView Notifications - Get Row/Col

[Gary Beene]

In the DDT world, I use this next line of code all the time, including within the dialog CallBack function, under various ListView notifications. It's easy enough to use.

ListView Get Select hDlg, %IDC_ListView to iRow

I also use these SDK code examples sometimes. But I don't have a complete listing of ListView notifications from which row/col can be extracted, nor the extraction code. These 5 notifications cover most of my needs but I wondered if anyone has documented how to get row/col for all ListView notifications from which row/col can be extracted? I'm not sure what all ListView notifications that involves.

   Local pLVDI As LV_DISPINFOW Ptr
   Local LVNT As NMItemActivate Ptr
   Local LVData As NM_ListView
   Local pNMLV As NMLISTVIEW Ptr

   Case %LVN_GetDispInfo
      pLVDI = Cb.LParam
      iRow = @pLVDI.item.iItem+1
      iCol = @pLVDI.item.iSubItem+1

   Case %NM_Click
      LVNT = Cb.LParam
      iRow = @LVNT.iItem+1
      iCol = @LVNT.iSubItem+1

   Case %NM_DblClk
      LVNT = Cb.LParam
      iRow = @LVNT.iItem+1
      iCol = @LVNT.iSubItem+1

   Case %LVN_ColumnClick
      Type Set LVData = Cb.NmHdr$(SizeOf(LVData))
      iRow = LVData.iItem+1
      iCol = LVData.iSubItem+1

   Case %LVN_ItemChanged  'Mouse Click or Keyboard Arrow will cause this
      pNMLV = Cb.LParam
      iRow  = @pNMLV.iItem+1
      iCol  = @pNMLV.iSubItem+1

And, of course, if there's anything wrong with this code, feedback is welcome.

%NM_RCLICK, using same code.
And then of course if LOCAL lplvcd AS NMLVCUSTOMDRAW PTR,
then @lplvcd.nmcd.dwItemSpec is line and @lplvcd.iSubItem is column under %NM_CUSTOMDRAW

You can also at any time - that is, you don't have to wait for a notification - get the mouse position with GetCursorPos(), convert to client coordinates with ScreenToClient (), then use the ListView_HitTest macro (or LVM_HITTEST message) to get the item and subitem (if any) at the cursor.

Your method in post #1 (LISTVIEW GET SELECT) of course does not work if the listview control is configured to support multiple selections OR if the cursor is not currently on the selected item. (depends on what you are doing).
