FtpWebRequest - Help Needed

[Die]

Alright, well now that I got my program working I need to make it so I can share it with other users.

Instead of having my Username and Password in the source, I want it to be "TextBox1.Text and TextBox2.Text.
I know this is an easy fix, I just have never had to do this so I'd appreciate it if someone helped.

My Code:

Code:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim request As System.Net.FtpWebRequest = DirectCast(System.Net.WebRequest.Create("ftp://ftp.drivehq.com/My+Documents/file.exe"), System.Net.FtpWebRequest)
        request.Credentials = New System.Net.NetworkCredential(("Textbox1.Text"), ("Textbox2.Text"))
        request.Method = System.Net.WebRequestMethods.Ftp.UploadFile

        Dim file() As Byte = System.IO.File.ReadAllBytes(TextBox3.Text)

        Dim strz As System.IO.Stream = request.GetRequestStream()
        strz.Write(file, 0, file.Length)
        strz.Close()
        strz.Dispose()
    End Sub

Problem:
request.Credentials = New System.Net.NetworkCredential(("Textbox1.Text"), ("Textbox2.Text"))

Doesn't show up as an Error, but when you use the program its self it doesn't log you in.

I will be willing to give the full source to a few users that I think would actually try to fix it.

If you help fix this, and would like to continue helping with problems I would greatly appreciate it and I will put you in the credits.
