In ​GUICtrlSetData: It says that the function can set data for a dummy control. In ​GUICtrlRead: It says that you can read the data stored in a dummy control, which is set either by GUICtrlSetData or GUICtrlSendToDummy.

A quick test point out that GUICtrlRead can only read data which is set by GUICtrlSendToDummy.

GUICreate(@AutoItVersion)
GUICtrlCreateDummy()
GUICtrlSetData(-1, 100, 101)
ConsoleWrite(@CRLF & GUICtrlRead(-1))
GUICtrlSendToDummy(-1, "Wow! It can store a string")
ConsoleWrite(@CRLF & GUICtrlRead(-1))

I don't know it is autoit bug or documentation bug, but this is absolutely a bug. But I think it may be easy to fix. Hope it's fixed ASAP.

The documentation state that

WinGetHandle("[LAST]")

should return "Last window used in a previous AutoIt command" (in "Window Titles and Text" section), and (in "WinGetHandle" section) "sets the @error flag to non-zero if the window is not found."

GUICreate("Test")
GUISetBkColor(0x0)
GUISetState()
;Local $hWin = WinGetHandle("[ACTIVE]")
;WinMove($hWin, "", 0, 0)

Local $hWin1 = WinGetHandle("[LAST]")
ConsoleWrite($hWin1 & ' - ' & @error  & ' - '& VarGetType($hWin1))
Sleep(2000)

First, the documentation do not say that it's only return the window which is processed with only Win...() function but not GUI...() function. This can make people misunderstood. Second, when no previous window is found, it NOT set @error at all. In the example above, it return a pointer with value 0, and @error also set to 0.

Example

#include 'FileConstants.au3'

$h = FileOpen('test.txt', $FO_OVERWRITE)
FileWrite($h, 'abcdef')
FileClose($h)

test(0)
test($FO_BINARY)
test($FO_UTF16_LE)
test($FO_UTF16_BE)
test($FO_UTF8)
test($FO_UTF8_NOBOM)
test($FO_UTF8_FULL)

Func test($FO)
  $h = FileOpen('test.txt', $FO_READ + $FO)
  $data = FileRead($h)
  FileClose($h)
  ConsoleWrite($data & " : " & IsBinary($data) & @CRLF )
EndFunc

3.3.12.0 output

abcdef : 0
0x616263646566 : 1
??? : 0
??? : 0
abcdef : 0
abcdef : 0
abcdef : 0

3.3.13.19 beta output

abcdef : 0
0x616263646566 : 1
0x63646566 : 1
0x63646566 : 1
0x646566 : 1
0x616263646566 : 1
abcdef : 0

Why all $FO_UTF* modes (except $FO_UTF8_FULL) return binary data?

If change string

FileWrite($h, 'abcdef')

to

FileWrite($h, ' ')

then "Error allocating memory" message will be shown for

test($FO_UTF16_LE)
test($FO_UTF16_BE)
test($FO_UTF8)
