Trouble with Textbox control

[anime8ted]

I am encountering a problem updating the text in a textbox on a form.

What I am trying to do is pass data using IPC remoting from a form called "Application" to a Windows Service called "Hub" and then on to a form called "Server" where the data is displayed.

Right now what I have is two forms each equipped with a button and a textbox control. Upon hitting the button in the "Application" form the value of the textbox on the same form is sent via IPC to the service then onto the "Server" form where I am trying to set the value of the textbox there to the data that I had sent via IPC.

I have been using MsgBoxes to confirm the transmission of data. I have confirmed sending the data from one form to the other but when I try to set the textbox control to the value of the data it does nothing. I have tested hard coding a value (i.e. txtText.Text = "New") for the control and it will display that fine however when I use the following:

Public Sub SetText(ByVal txt As String)
MessageBox.Show(txt & " again")
txtText.Text = txt.ToString()
End Sub

I get nothing, even though the message box will display "12345 again" when I send "12345" as the data, my textbox doesn't reflect any changes.

It is ironic that something this simple is giving me more trouble than working with IPC .

Anyway, any help would be appreciated.

Thanks

Why dont you try:

txtText.Text = txtText.Text & txt

Lele, I tried your suggestion but still no dice.

Here is the code used to try and set the textbox to the right value:

 Public Sub SetText(ByVal txt As String)

        ' MessageBox used to confirm the transmission of data
        MessageBox.Show(txt & "Again")

        ' Displays any received data in the Textbox control
        txtText.Text = txt.ToString

    End Sub

Its is just weird that the message box will display the right text but the textbox wont change at all.

That is strange, but you don't need to do txt.toString() seeing as how it is already as string. I have never done this so I don't know if this is what could be giving you the problem. You never know, sometimes things like this can produce strange results.

I removed the .toString() from the code, still no luck as of yet.

I am beginning to wonder if I need to close down the IPC channel that sent the data in order for it to be displayed. I don't know why this would be the case though.

Anyway I would like to thank you guys for posting your suggestions. I posted this question to the msdn forum a month ago and never received any hits.
