      Hey there!
      I'm gonna try to get access to an RichEdit Control in PSPad with Autoit which is scripted with Delphi. I wrote the commands out ouf the RichEdit.au3 UDF to can change them, because it always fails or crashs, when i call it. I Just want to set the Textcolor for the RichEdit.
      It seems to be a Problem with $EM_SETCHARFORMAT... (maybe protected?) I can use e.g. $EM_SETBKGNDCOLOR or other messages with no error. Sadly it doesn't exist a message constant to just set the textcolor... This is what i already tried:
      use $EM_GETCHARFORMAT but it crashs/doesn't work too. I saw the riched20.dll is linked to GDI+ but i couldn't make something work with it... (GetDc and so on but maybe there is another way?) Tried to set some other style on it (setWindowLong) I read the MSDN about $EM_SETCHARFORMAT up and down, but i can't find any other solution.
      The RichEdit should be version 2 ( error message point to riched20.dll )
       
      Here is the PSPad that will be required for testing:
      https://autoit.de/wcf/attachment/87712-pspad4autoit3-v1-0-0-beta-without-setup-zip/
      You need to start PSPad.exe first!

      I would be happy for every idea  
       
      Thanks in advance

      This UDF allows to create formatted label using pseudo element RichLabel (RichEdit actually). Formating is set by using special modificator similar to <font> tag in Html.
      Notes: This UDF is a transformation-continuation of related UDF


      Example:
      Download:
      GUIRichLabel_1.2.zip

      If you look at the help file for the above command, you'll see that it states that it only works for certain zoom values (100 and 200 to 6400).   I assume that this is due to an issue in an MSDN library that the command relies on.
      After doing some investigating, I noticed that the GUIRichEdit.au3 library file contains the following code:
      ; #FUNCTION# ==================================================================================================================== ; Authors........: Chris Haslam (c.haslam) ; Modified ......: ; =============================================================================================================================== Func _GUICtrlRichEdit_SetZoom($hWnd, $iPercent) If Not _WinAPI_IsClassName($hWnd, $__g_sRTFClassName) Then Return SetError(101, 0, False) If Not __GCR_IsNumeric($iPercent, ">0") Then Return SetError(1021, 0, False) Local $iNumerator, $iDenominator Select Case Not ($iPercent = 100 Or ($iPercent >= 200 And $iPercent < 6400)) Return SetError(1022, 0, False) Case $iPercent >= 100 $iNumerator = 10000 $iDenominator = 10000 / ($iPercent / 100) Case Else $iNumerator = 10000 * ($iPercent / 100) $iDenominator = 10000 EndSelect Return _SendMessage($hWnd, $EM_SETZOOM, $iNumerator, $iDenominator) <> 0 EndFunc ;==>_GUICtrlRichEdit_SetZoom Which ensures that values are only within the bounds specified in the help file.    I found that if I comment out the portion of the code that limits the values, the function works fine for most (if not all) values.   I changed the code in the library file to this by simply commenting out the restricting lines of code:
      ; #FUNCTION# ==================================================================================================================== ; Authors........: Chris Haslam (c.haslam) ; Modified ......: ; =============================================================================================================================== Func _GUICtrlRichEdit_SetZoom($hWnd, $iPercent) If Not _WinAPI_IsClassName($hWnd, $__g_sRTFClassName) Then Return SetError(101, 0, False) If Not __GCR_IsNumeric($iPercent, ">0") Then Return SetError(1021, 0, False) Local $iNumerator, $iDenominator Select ; Case Not ($iPercent = 100 Or ($iPercent >= 200 And $iPercent < 6400)) ; Return SetError(1022, 0, False) Case $iPercent >= 100 $iNumerator = 10000 $iDenominator = 10000 / ($iPercent / 100) Case Else $iNumerator = 10000 * ($iPercent / 100) $iDenominator = 10000 EndSelect Return _SendMessage($hWnd, $EM_SETZOOM, $iNumerator, $iDenominator) <> 0 EndFunc ;==>_GUICtrlRichEdit_SetZoom  
      I assume whatever windows bug existed at the time this was created, no longer exists so there is no need to restrict the values.   
      Just wanted to point this out if anyone else is using this part of the library and required this functionality like I did.

      Tell me, please, how to set / change the cursor over RichEdit (created with _GUICtrlRichEdit_Create)?
    • By StMaSi
      Two questions...
      When presenting a form containing a richedit control, is there any way to make the displayed text, within said richedit control, non-selectable?
      In addition, is there any way to hide the vertical line cursor, within said richedit control?
      Thanx.
