Changing text color of _GUICtrlEdit_AppendText

[Rodger]

Hello,

I have the following:

$C1 = _GUICtrlEdit_AppendText($MessageBox, " Prio 1 ")

$C2 = _GUICtrlEdit_AppendText($MessageBox, " Prio 2 ")

GUICtrlSetColor($C1, $COLOR_RED)

GUICtrlSetColor($C2, $COLOR_BLUE)

But it doesn't work. every line appears in blue instead of the first one in red and the second in blue.

Is there any way to accomplish this?

Thkx,

Rodger
