If I do Code:
dim $objConn
i get an error message saying that $objConn is a duplicate definition. and yes, $objConn is "dimmed" in some of the UDFs included:

Code:

Function DBConnOpen($objConn, optional $ConnTimeout, optional $CmdTimeout)

	Dim $objConn, $adStateOpen

	$dbconnopen=''
	$adStateOpen=1

	if vartype($ConnTimeout)
		$ConnTimeout=val($ConnTimeout)
	else
		$ConnTimeout=15
	endif

	if vartype($CmdTimeout)
		$CmdTimeout=val($CmdTimeout)
	else
		$CmdTimeout=30
	endif

	$ConnDSN=trim($ConnDSN)
	if not $ConnDSN
		exit 87
	endif

	$objConn = CreateObject("ADODB.Connection")
	if @ERROR
		exit @ERROR
	endif

	$objConn.ConnectionTimeout = $ConnTimeout
	if @ERROR
		exit @ERROR
	endif

	$objConn.CommandTimeout = $CmdTimeout
	if @ERROR
		exit @ERROR
	endif

	$objConn.Open($ConnDSN)
	if @ERROR
		exit @ERROR
	endif

	if not $objConn.State=$adStateOpen
		$objConn=''
		$DBConnOpen=''
		exit @ERROR
	endif
	
	$DBConnOpen=$objConn
	exit 0

EndFunction



Function DBConnClose($objConn)
    Dim $adStateOpen
    
    $adStateOpen = 1
    
    If vartype($objConn)=9
        If $objConn.State = $adStateOpen
            $objConn.Close()
            if @ERROR
                exit @ERROR
            endif
        EndIf
        $objConn=''
    else
        exit 87
    endif
    
    $DBConnClose=@ERROR
EndFunction



function DBExecuteSQL($objConn, $sql, optional $cmdType)
	dim $cmdCommand, $rsRecordset
