Is it possible to batch convert csv to xls using a macro?

Question

I have a large amount of csv files that I need in .xls format. Is it possible to run a batch conversion with a macro or best done with another language?

I have used this code http://www.ozgrid.com/forum/showthread.php?t=71409&p=369573#post369573 to reference my directory but I'm not sure of the command to open each file and save them. Here's what I have:

Sub batchconvertcsvxls()
    Dim wb As Workbook
    Dim CSVCount As Integer
    Dim myVar As String

    myVar = FileList("C:\Documents and Settings\alistairw\My Documents\csvxlstest")
    For i = LBound(myVar) To UBound(myVar)

        With wb

            Application.Workbooks.OpenText 'How do I reference the myvar string ?
            wb.SaveAs '....

        End With

    Next
End Sub

Function FileList(fldr As String, Optional fltr As String = "*.*") As Variant
    Dim sTemp As String, sHldr As String
    If Right$(fldr, 1) <> "\" Then fldr = fldr & "\"
    sTemp = Dir(fldr & fltr)
    If sTemp = "" Then
        FileList = Split("No files found", "|") 'ensures an array is returned
        Exit Function
    End If
    Do
        sHldr = Dir
        If sHldr = "" Then Exit Do
        sTemp = sTemp & "|" & sHldr
    Loop
    FileList = Split(sTemp, "|")
End Function

Edit: The files are .txt files formatted as csv

By combining the code given by Scott Holtzman and 'ExcelFreak', the conversion works quite well. The final code looks something like this:

Sub CSV_to_XLS()

Dim wb As Workbook
Dim strFile As String, strDir As String

strDir = "U:\path\"
strFile = Dir(strDir & "*.csv")

Do While strFile <> ""

    Set wb = Workbooks.Open(Filename:=strDir & strFile, Local:=True)
    wb.SaveAs Replace(wb.FullName, ".csv", ".xls"), 50 'UPDATE:
    wb.Close True

    Set wb = Nothing
    strFile = Dir
Loop

End Sub

Opening the converted .xls file throws a warning everytime:

"The file you are trying to open, 'filename', is in a different format than specified by the file extension. Verify that the file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now?"

Clicking Yes then opens the .xls file.

Is there a way to get rid of this warning message? Excel throws a warning everytime the .xls file is opened.
