filtering which files can be opened

I have created a program that opens a file and counts words, characters,
sentences, etc. I have not used the open file dialog control found in the VB
..NET 2003 toolbox. I instead have used Open.ShowDialog(). What I want to do
is filter the open file so that only text files (*.txt) can be opened.

The project I am working with has two projects and one solution. The main
project uses Open as the variable for the Open file dialog. the The second
project uses Obj.Openfile.

Charlie,

Can you show us a little piece of code.
Open.ShowDialog confuses me (and probably others as well), it means a form
that you have instanced as Open and shows it than.

OpenFileDialog has a 'Filter' property...

Here is the code which is being used to open a file and then process words,
characters, etc. What I want to do is filter the file types so that only
text files can be opened.

Private Sub btnAnalyzeFile_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles btnAnalyzeFile.Click

        Me.txtBoxInput.Clear()

        Dim Open As New OpenFileDialog

        Dim Obj As New Unit5ClassLibrary.StringProcessor.StringProcessor

        Try

            If Open.ShowDialog() = DialogResult.OK Then

                Obj.Openfile(Open.FileName)

                Me.txtBoxCharacters.Text = Obj.characters

                Me.txtBoxWords.Text = Obj.words

                Me.txtBoxSentence.Text = Obj.sentences

                Me.txtBoxParagraph.Text = Obj.paragraphs

            End If

        Catch er As Exception

            MsgBox(er.Message)

        Finally

        End Try

    End Sub
