can i use a handle for the filename instead of specifying it exactly?

$file = FileOpen("c:\test.txt", 0)
If $file = -1  Then
     MsgBox(0, "Unable to open file","")

$count = _FileCountLines($file)

You don't really even need to do that. Here is a simple line count. It will work with either a full file or a block of text from the clipboard or any other place.

MsgBox(0, "Line Count", _LineCount(@DeskTopDir & "\somefile.txt") & " lines")

Func _LineCount($sStr)
   If FileExists($sStr) Then $sStr = FileRead($sStr)
   $aRegExp = StringRegExp($sStr, "(?i)(?m:^)(.*)(?:\v|\z)", 3)
   Return Ubound($aRegExp)
