This is an example script, showing how to avoid having Richedit control stealing focus from other controls. I have seen several person on the forum having the same issue as me. When using a RichEdit Control in a chat software, RichEdit steals focus from the Input everytime a user posts a message. I think I found a work around : find a way to append the text without making a text selection, because the selection moves the caret in the richedit control. Problems and solutions I found : 1 - "_GUICtrlRichEdit_AppendText" Steals focus because there is "_GuiCtrlRichEdit_SetSel" in the function ( "_GuiCtrlRichEdit_SetSel" is used to input the text at the end of the richedit control, and also used to scroll the page to the last line ). --- > AppendText Solution = I use "_GUICtrlEdit_AppendText" from "GuiEdit.au3". It appends the text at the end of the Richedit Control, without moving the caret to the richedit control. --- > Scrolling Solution = I used "_GUICtrlRichEdit_ScrollLines" to scroll one line down. Later I'll try to find how many lines really need to be scrolled ( if multiline text ). 2 - "_GUICtrlRichEdit_SetCharColor" Also needs a selection to apply the color. ( _GUICtrlRichEdit_SetFont Doesn't need a selection ) --- > Color solution = I edited the "_GUICtrlRichEdit_SetCharColor" by Jpm ( and named it "_GUICtrlRichEdit_SetCharColor_No_Selection" ) and commented the _GuiCtrlRichEdit_GetSel lines. So the color needs to be chosen before appending the text. Here is an example script showing the problem ( I tried to simulate a chat situation ) : ;INCLUDES #include <GuiRichEdit.au3> #include <GUIConstantsEx.au3> #include <WindowsConstants.au3> ;OPT Opt("GUIOnEventMode", 1) ;VARIABLES GUI Global $GUI_SIZE_X = 600 Global $GUI_SIZE_Y = 600 Global $GUI_RICHEDIT_SIZE_X = $GUI_SIZE_X Global $GUI_RICHEDIT_SIZE_Y = $GUI_SIZE_Y / 3 ;GUI Global $GUI = GUICreate("Test", $GUI_SIZE_X, $GUI_SIZE_Y) ;RICHEDIT Global $GUI_RICHEDIT = _GUICtrlRichEdit_Create($GUI, "", 0, 0, $GUI_RICHEDIT_SIZE_X, $GUI_RICHEDIT_SIZE_Y * 2, BitOR($ES_MULTILINE, $WS_VSCROLL, $ES_AUTOVSCROLL, $ES_READONLY)) ;INPUT Global $sINPUT_TEXT = "Try to Type some text here !

Use "Enter" to send the text in the Richedit control. Well I hope that solves the problems that others had before. [EDIT1] I ran "tidy" on the scripts for better formatting.

Trying to enter colored text into a rich edit is a pain in the ass and complicated, and after searching for a few hours I always end up in the help file staring at this text: _GUICtrlRichEdit_SetText ( $hWnd, $sText ) Parameters $hWnd Handle to the control $sText Plain or RTF text to put into the control What is this RTF text it speaks of? What I am THINKING of is how if you copy bold text from a page, and paste it into wordpad, it is bold. But if you paste that text into notepad and then copy it and paste it into wordpad it will have no formatting. There is some kind of extra formatting that can be on the text in clipboard In the same way if you _GUICtrlRichEdit_SetText with plain text it sends it in the richedit as plain text. How do I send pre-formatted "RTF text" to a richedit using _GUICtrlRichEdit_SetText?

I found this example by zedna, it worked perfectly (entering text into the control with specified color), that is until you add any form of line break (@CR, @LF or @CRLF). If the line breaks aren't there, the text entered is colored correctly, but when they are, the colors gets off and I can't figure out why, anyone know what's the matter? #include <GUIConstants.au3> #include <GuiRichEdit.au3> #include <EditConstants.au3> #include <GUIConstantsEx.au3> #include <WindowsConstants.au3> $Form1 = GUICreate("Form1", 448, 269, 192, 124) $Edit1 = _GUICtrlRichEdit_Create($Form1,"", 16, 24, 417, 225) GUISetState(@SW_SHOW) _GUICtrlRichEdit_AppendTextColor($Edit1, "Hello "& @CR, "0x00FF00") _GUICtrlRichEdit_AppendTextColor($Edit1, "Autoit "& @CR, "0xFF0000") _GUICtrlRichEdit_AppendTextColor($Edit1, "World", "0x000000") ;~ _GUICtrlRichEdit_AppendText($Edit1, "World") While 1 $nMsg = GUIGetMsg() Switch $nMsg Case $GUI_EVENT_CLOSE _GUICtrlRichEdit_Destroy($Edit1) Exit EndSwitch WEnd Func _GUICtrlRichEdit_AppendTextColor($hWnd, $sText, $iColor) Local $iLength = Int(_GUICtrlRichEdit_GetTextLength($hWnd)/2) ; RichEdit stores text as 2 Byte Unicode chars _GUICtrlRichEdit_AppendText($hWnd, $sText) _GUICtrlRichEdit_SetSel($hWnd, $iLength, $iLength + StringLen($sText)*2) ; position in 2 Byte "Unicode" _GUICtrlRichEdit_SetCharColor($hWnd, $iColor) _GuiCtrlRichEdit_Deselect($hWnd) EndFunc
