problem with getdisplaytext using interop.reflection/reflectionhost

Hi good day , Im developing an application to extract information from reflection, my problem is that it seems like the application is not storing the data everytime I run it, sometimes it stores some of ir others it doesnt. Would like to know if someone knows of a solution for this without thread.sleep.

My code:

Code:

---

  Public Class _Reflection
    Public MyWRQ As Reflection.Session
    Public Sub Session_Connect(ByVal User As String, ByVal Password As String, Optional visible As Boolean = False)
        MyWRQ = New Reflection.Session
        With MyWRQ
            .Visible = visible
            .OpenSettings(1, "\Program Files (x86)\\Reflection\tnp1.rsf")
            .Connect()
            .HostcommTimeout = 10
            WaitForString("APPLICATION", 8, 7)
            Evento(HostEventos.Atposition, 9, 18)
            .TransmitANSI("MXMP")
            .TransmitTerminalKey(HostEventos.rcIBMEnterKey)
            WaitForString("Userid", 23, 3)
            Evento(HostEventos.Atposition, 23, 11)
            .TransmitANSI(User)
            .TransmitTerminalKey(HostEventos.rcIBMTabKey)
            .TransmitANSI(Password)
            .TransmitTerminalKey(HostEventos.rcIBMEnterKey)
        End With
    End Sub
    Public Sub SendTerminalKeys(ByVal key As Integer)
        MyWRQ.TransmitTerminalKey(key)
        MyWRQ.WaitForEvent(1, "150", "0", 1, 1)
    End Sub
    Public Function GetString(ByVal Row As Integer, ByVal Column As Integer, ByVal CharLength As Integer) As String

        MyWRQ.WaitForEvent(1, "150", "1", 1, 1)
        Do Until MyWRQ.GetDisplayText(Row, Column, CharLength).Trim <> "" : Loop
        Return MyWRQ.GetDisplayText(Row, Column, CharLength).Trim
    End Function
    Public Sub WaitForString(ByVal Str As String, ByVal Row As Integer, ByVal Column As Integer)
        MyWRQ.WaitForDisplayString(Str, "150", Row, Column)
        MyWRQ.WaitForEvent(1, "150", "0", 1, 1)
    End Sub
    Public Sub Evento(ByVal Evento As Integer, ByVal Row As Integer, ByVal Column As Integer)
        If Evento = 6 Then
            MyWRQ.WaitForEvent(1, "150", "0", 1, 1)
            MyWRQ.WaitForEvent(6, "150", "0", Row, Column)
        Else
            MyWRQ.WaitForEvent(Evento, "150", "0", Row, Column)
        End If
    End Sub
    Public Sub MoveCursor(ByVal Row As Integer, ByVal Column As Integer)
        MyWRQ.MoveCursor(Row, Column)
    End Sub
    Public Sub Session_Disconnect()
        MyWRQ.Exit()
    End Sub
end class

this is the part where it sometimes store some of the values on some of the variables others it doesnt

Code:

---

    Public Sub RESETSCRN(ByVal Hst As ReflectionHost._Reflection, ByVal Screen As String)
        With Hst.MyWRQ
            .TransmitTerminalKey(ReflectionHost._Reflection.HostEventos.rcIBMClearKey)
            Hst.Evento(1, 1, 46)
            Hst.MyWRQ.TransmitANSI(Screen)
            .TransmitTerminalKey(ReflectionHost._Reflection.HostEventos.rcIBMEnterKey)
            Hst.Evento(1, 1, 46)
        End With


    End Sub

public sub process()
RESETSCRN(Hst, "IINQ")
            Hst.WaitForString("ARTC", 1, 2)
            Hst.MyWRQ.TransmitANSI("100297910")
            Hst.SendTerminalKeys(ReflectionHost._Reflection.HostEventos.rcIBMEnterKey)
            IINQCWO = Hst.GetString(19, 25, 1)      'CANCEL WHEN OUT N
            IINQREPLN = Hst.GetString(8, 9, 5)      'RESURTIBLE 33,37,20
            IINQACTIVE = Hst.GetString(1, 19, 6)    'STATUS ACTIVO
            IINQMBM = Hst.GetString(19, 12, 1)      'MBM M O I
            IINQVIGENCIA = Hst.GetString(18, 37, 8)  'VIGENCIA ABIERTA
end sub

thanks a lot

found the problem , dont quite get the difference between both but theres a getfieldtext method which is working correctly insted of getdisplaytext
