Opening Files into child window textbox

I get this error

Quote:

---

Additional information: Invalid file format.

I am using this code

VB Code:

If OpenFileDialog.ShowDialog() = DialogResult.OK Then
            Dim Child As frmChild
            Child = New frmChild
            Child.MdiParent = Me
            Child.Show()
            Child.ActiveForm.Text = OpenFileDialog.FileName
            Child.txtBoxChild.LoadFile(OpenFileDialog.FileName)
        End If

What's wrong?

I'm just trying to open a plain ole text file into a rich text box...

you are missing a vital bit in the LoadFile of the richtextbox :

VB Code:

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        Dim od As New OpenFileDialog()
        od.InitialDirectory = "C:\"
        If od.ShowDialog = DialogResult.OK Then
            RichTextBox1.LoadFile(od.FileName, RichTextBoxStreamType.PlainText)
        End If
    End Sub

RichTextBoxStreamType.PlainText
^^^ being the bit.

Thanks, that works :D
