John Thanks but I have the want return, vertical scroll and AutoVScroll set and the text does not scroll. I snapshot the text already in the Edit Box (if any) with GetDlgItemText(hWnd, IDC_EDIT3,textBuff,1024), then add the new text to it and use SetWindowText(hWnd,IDC_EDIT3 ,textBuff) to display the text to IDC_EDIT3. The Vertical Scroll Bar is being updated (it changes size) but I cannot move it and the text is not scrolling down. Any other ideas ? Thx G. Weideman
