The GetText method is the simplest way to read data from the screen buffer.

VB.NET

[String =] tnxxxx.GetText (StartPos As Integer, [EndPos As Integer], [Attr As Boolean = False], [Eab As Boolean = False])

[String =] tnxxxx.GetText (Row As Integer, Col As Integer, Len as Integer, [Attr As Boolean = False], [Eab As Boolean = False])

C#

[string =] tnxxxx.GetText (int StartPos, [int StartPos], [bool Attr = False], [bool Eab = False]);

[string =] tnxxxx.GetText (int Row, in Col, int Len, [bool Attr = False], [bool Eab = False]);

Start position and the end position of the text buffer to retrieve can be set using StartPos and EndPos parameters or Row,Col and Len parameters.

 VB.NET:

 Private Sub tn3270_OnScreenChange(eventSender As object, eventArgs As System.EventArgs)

        ' this code gets the Text from position 150

    Dim s As String = tn3270.GetText(150)

         ...

        ' this code gets the Text from position 150 to 200

    Dim s As String = tn3270.GetText(150,200)

         ...

        ' this code gets the Text from row 15 column 4 with a lenght of 20

    Dim s As String = tn3270.GetText(15,4,20)

 End Sub

 C#:

 private void tn3270_OnScreenChange(object eventSender, System.EventArgs eventArgs)

 {

        // this code gets the Text from position 150

    string s = tn3270.GetText(150);

         ...

        // this code gets the Text from position 150 to 200

    string s = tn3270.GetText(150,200);

         ...

        // this code gets the Text from row 15 column 4 with a lenght of 20

    string s = tn3270.GetText(15,4,20);

 }
