Func _WinAPI_GetLastErrorMessage()
  Local $tText

  $tText = DllStructCreate("char Text[4096]")

 _WinAPI_FormatMessage($__WINAPCONSTANT_FORMAT_MESSAGE_FROM_SYSTEM, 0, _WinAPI_GetLastError(), 0, DllStructGetPtr($tText), 4096, 0)
  Return DllStructGetData($tText, "Text")
EndFunc   ;==>_WinAPI_GetLastErrorMessage

The 'nSize' parameter passed is not accounting for the terminating null character: it should be 4095, or the array size should be changed to 4097, according to ​MSDN's example code.

Another solution (a more elegant one, in my view) is letting FormatMessage allocate the buffer. The attached file contains a implementation of this method.

Thank you, Daniel

After install/uninstall of beta 3.3.1.4 include file WinAPIError.au3 was not uninstalled.

It's similar to older ticket #1121

Example for _GuiCtrlRichEdit_SetCharColor() saves RTF file which should contain whole text of richedit control. But instead of "Paragraph 1" RTF file contains only "aph 1".

Note: In this example parts of word was formatted differently

So maybe this is more related (bug) in _GuiCtrlRichEdit_StreamToFile() but I'm not sure about the place where is cause of this bug.

Example from helpfile:

#AutoIt3Wrapper_Au3Check_Parameters= -d -w 1 -w 2 -w 3 -w 4 -w 5 -w 6
#include <GuiRichEdit.au3>
#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <Color.au3>
