Get Access to RichEdit (Log) in PSPad with Autoit

Recommended Posts

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:


You need to start PSPad.exe first!

I don't have any ideas anymore :( But maybe someone else has?

I would be happy for every idea :P 


Thanks in advance

why do i get garbage when i buy garbage bags? <_<

      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

      PSPad4AutoIt3 consists of the Editor PSPad and the Improvement Kit, and can be used as an portable Editor IDE for AutoIt3.
      The author of the PSPad Editor is Jan Fiala. I (Professor Bernd) am only the author of the Improvement Kit.
      After months of work, PSPad4AutoIt3 version 1.0.0 beta is now ready.  
      I like to call it the "first real" version, because the Improvement Kit now handles a lot of things autonomously. So PSPad remains operable when an au3 script is started. Also there is now a setup that makes the installation easier. 👍 And for those who don't like/do not want an installer, there is a download without setup. Without setup, the user has to take care of the prerequirements himself. Only recommended for experienced users.
      The core functionalities "Run, Check Syntax, Compile and Comile Dialog" are integrated and work very well. Thanks to @Jos for extending AutoIt3Wrapper!  There are also a few more features that you can find in the main menu, menu item "Scripts" => "_AutoIt". These include "Debug to Console", "Debug to MsgBox" and the "Koda FormDesigner" as a helper for creating GUIs. In this menu there is also an item "_Tips and shortcuts". After a click the AutoIt-relevant shortcuts are displayed.
      The language in the menu "_AutoIt" is English. The language for PSPad in general can be set for more than 40 languages (Main menu => Settings => Program Settings => Language).
      PSPad4AutoIt3 is in a beta stage and does not have many features yet. But I am working on it!
      More information (EN, DE) and the download can be found in my PSPad4AutoIt3 Projekt in the AutoIt.de forum.
      I would be glad if you have a look at it and write me your opinion. Have fun!
      2020-04-20 Important note: The minimum version for AutoIt3 HAS TO BE!

      I had hoped that the changes would not be so severe, so in the downloads the minimum version is still indicated. Unfortunately, it has recently become apparent that with older versions the main functions, e.g. CompilerRunner, the AutoIt3 Help and the upcoming CallTipViewer, fail.

      The downloads can be used so far, but everybody has to take care of the AutoIt3 version by himself!
      Thank you very much,

      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?
