_GUICtrlRichEdit_SetEventMask ($hWnd, $iEventMask)

For $iEventMask, the AutoIt-Help also states $ENM_NONE, but this constant is undeclared in RichEditConstants.au3.

_GUICtrlRichEdit_SetEventMask ($hWnd, $ENM_NONE) ; warning: $ENM_NONE: possibly used before declaration.

On this example:

; Begin of test.au3 test(1)

Func test($x, $y = $z) ; $z is not declared. EndFunc ; End of test.au3

This script causes the following error:

test(1) test(1) ^{ERROR Error: Variable used without being declared.}

However, it is no "variable" found in this line. The actual problem is in $z, so the following error message will be more readable:

Func test($x, $y = $z) Func test($x, $y = ^{ERROR Error: Variable used without being declared.}

This script demonstrates a bug in repeated calls to GUICtrlSetData() to add a single value to a list where that value already exists in the list. The value is not appended to the list unless there is a pipe character after the value.

; only one entry apeers in list

$mylist2 = GUICtrlCreatelist ("", 10,200)
