Hello,
I would like to change the cursor when the mouse is over a cell in my ClistCtrl.
I have enclosed the code when I am with the mouse over a Static Item.
How can I get the row and col into a Crect, to calculate the position of the cusor?
Please let me know. 500 points with a solution.
Please consider I am a beginner in MFC.
Thanks.
Best regards,
Thomas

You can use SubItemHitTest().

Here is an example:
int CListViewEx::PointToSubItem( CPoint pt )

{

	CListCtrl& lc = GetListCtrl();
 

	LVHITTESTINFO  hti;

	hti.pt = pt;

	lc.ScreenToClient( &hti.pt );
 

	if ( lc.SubItemHitTest( &hti ) >= 0 )

		return hti.iSubItem;
 

	return -1;

}

You can add a handler for WM_MOUSEMOVE message and call SubItemHitTest from there.

It should be something like that:
void CMyProgram::OnMouseMove(UINT nFlags, CPoint point)

{

   CDialog::OnMouseMove(nFlags, point);
 

   // convert from dialog coordinate to screen coordinate

   ClientToScreen( &point );
 

   // get the list control

   CListCtrl* pList = GetDlgItem( IDC_LISTCONTROL );
 

   // convert from screen coordinate to control coordinate

   pList->ScreenToClient( &point );
 

   LVHITTESTINFO  hti;

   hti.pt = point;

   switch( pList->SubItemHitTest( &hti ))

   {

     case LVHT_ONITEMICON:

     case LVHT_ONITEMLABEL:

     {

       // you are over an item

       int nRow = hti.iItem;

       int nCol = hti.iSubItem;
 

       ... do something ....

     }

     break;

   }

 
 

   

}
