Initial Code

{
   int nLength = editArg.GetWindowTextLength(); // get the initial text length
   editArg.SetSel(nLength, nLength); // put the selection at the end of text
   editArg.ReplaceSel("
"); // replace the selection
   nLength+=2;
   editArg.SetSel(nLength, nLength); // put the selection at the end of text
   editArg.ReplaceSel(pszTextArg); // replace the selection

Initial Description

Set textbox to multi-line. ASSERT statement verifies.

Apparently executes quicker than GetWindowText, Append, SetWindowText.

Appears to auto-scroll otherwise, use this to scroll to bottom:
edit.SendMessage(WM_VSCROLL, SB_BOTTOM, 0 );

Haven't figured out how to stop scrolling when it's not already at the bottom.
