Fejl kan ikke finde C.Value i System.Windows.Forms.Control

Jeg har denne kode som er lavet i Visual Basic 6. Når jeg konvertere den og åbner den i Visual Studio 2008 kommer den med en fejl fordi at den ikke kan finde C.Value i System.Windows.Forms.Control. Hvad skal jeg gøre. På forhånd tak

Public Sub SaveIni()
        Dim i As Short
        Dim C As System.Windows.Forms.Control
        WriteIniString("FileId", "therm")
        On Error Resume Next
        For    Each C In frm_thermometer.Controls
            WriteIniString("frm_thermometer." & C.Name & ".caption", C.Text)
