        Invoke(d, New Object() {achidrtb, "", "="})
        Invoke(d, New Object() {hiddenrtb2, "", "="})
        Invoke(d, New Object() {resultrtb, "", "="})
        Invoke(d, New Object() {successes, "0", "="})
        Invoke(d, New Object() {fails, "0", "="})
        Invoke(d, New Object() {checkednum, "0", "="})
        allowcheck = True
        Dim linenum As Integer = 1
        Dim accchk As String
        Dim SErr As New TSteamError()
        Dim iSteamReturn As Integer = 0
        Dim isLoggedIn As Integer = 0
        Dim sHandle As System.UInt32
        Dim startoptions As System.UInt32 = 15
        iSteamReturn = SteamStartEngine(SErr)
        iSteamReturn = SteamIsLoggedIn(isLoggedIn, SErr)
        iSteamReturn = SteamStartup(startoptions, SErr)
        Dim TProgress As New TSteamProgress()
        TProgress.Valid = 1
        i = 0
        Invoke(mul, New Object() {"x"})
        Invoke(d, New Object() {hiddenrtb2, mu, "="})
        Dim numlines As Integer = 0

        Dim List As String() = hiddenrtb2.Lines
        Dim Line As String
        For Each Line In List
            numlines = numlines + 1
        Next Line
        Invoke(d, New Object() {acclistnum, numlines.ToString(), "="})
        While numlines > 0
            Dim line2 As String
            line2 = hiddenrtb2.Lines(linenum - 1)
            numlines = numlines - 1
            linenum = linenum + 1

any help would be appreciated.

Cross-thread operation not valid: Control 'hiddenrtb2' accessed from a thread other thread

im getting this error and i cant figure it out.

It means that you made a control (hiddenrtb2) on one thread, but are trying to affect it from a different thread. That's not generally allowed.

If you want to access that control, you have to do it from the same thread that created it.
