Auto it help please please

I need a simple script in autoit that can open two text files and compare numbers withing them and decide which one is bigger for an update program im creating.

Thanks

Some use this method. This will work so long as the versions are not padded with leading zeros.

If Not FileExists('file1.txt') And Not FileExists('file2.txt') Then
	; create test files
	If FileWrite('file1.txt', '2.1.1.0') And FileWrite('file2.txt', '1.1.1.0') Then
		ConsoleWrite('Test files written' & @CRLF)
	EndIf

	; Read test files and compare versions
	$file1 = StringStripWS(FileRead('file1.txt'), 3)
	$file2 = StringStripWS(FileRead('file2.txt'), 3)
	If $file1 > $file2 Then
		MsgBox(0x40000, '', $file1 & ' > ' & $file2 & @CRLF)
	EndIf

	; remove test files
	If FileDelete('file1.txt') And FileDelete('file2.txt') Then
		ConsoleWrite('Test files removed' & @CRLF)
	EndIf
EndIf

To have a more thorough method then use StringSplit to split the version into elements that can be compared numerically.

If Not FileExists('file1.txt') And Not FileExists('file2.txt') Then
	; create test files
	If FileWrite('file1.txt', '2.1.1.0') And FileWrite('file2.txt', '2.2.1.0') Then
		ConsoleWrite('Test files written' & @CRLF)
	EndIf

	; Read test files and compare versions
	$file1 = FileRead('file1.txt')
	$file2 = FileRead('file2.txt')
	If _HigherVersion($file1, $file2) And Not @error Then
		MsgBox(0x40000, '', 'Higher version')
	ElseIf @error Then
		MsgBox(0x40000, 'Error', @error)
	EndIf

	; remove test files
	If FileDelete('file1.txt') And FileDelete('file2.txt') Then
		ConsoleWrite('Test files removed' & @CRLF)
	EndIf
EndIf

Func _HigherVersion($current, $update)
	$current = StringSplit($current, '.')
	If @error Then Return SetError(1, 0, '')
	$update = StringSplit($update, '.')
	If @error Then Return SetError(1, 0, '')
	If $current[0] <> $update[0] Then Return SetError(2, 0, '')
	For $i = 1 To $current[0]
		If Int($current[$i]) = Int($update[$i]) Then
			ContinueLoop
		ElseIf Int($current[$i]) < Int($update[$i]) Then
			Return True
		EndIf
	Next
EndFunc

Thanks for taking this one MHz, we don't see much of you these days especially in the programming forum!

Those are both fantastic thank you very much.

They have helped me alot. i hope to release a program soon because of your help
