Is there a way to control / trigger the windows scroll event?

 

Let's say I have window_1. Window_1 has a vertical scroll bar.

I have 5 dw's lined up vertically on the window so I need a vertical scroll bar on the window to place/view all of the dw's. Dw_5 is not visible on the window until I scroll to the bottom of the window. How could I click on a button at the top of the window and have the window scroll to the dw at the bottom?

Hi Robert;

  This code works for me ...

Int		li_loop
Parent.SetRedraw( FALSE )
FOR li_loop =1 to 20
	Send ( Handle ( Parent ), 277, 3, 0 )
next
Parent.SetRedraw( TRUE )

   The SEND command is sending a mouse click on the Scrollbar like you were requesting a page down. So I added a loop to simulate a page down enough times to get to the bottom of my test window. You may have to adjust the loop count to accommodate your window sizing.

HTH

Regards .. Chris
