I need help with a Spam Bot (Spammer)

[groso5]

I was making a spammer for my friend's private silkroad server...well what ever
My Proplem is that i want the text boxes to get spammed in order
ex. when the first textbox is written it auto clicks enter then writes the second textbox and enter and so on
I belive that the proplem is in the timer.

    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
        If CheckBox1.Checked = True Then
            SendKeys.Send(TextBox1.Text)
            SendKeys.Send("{Enter}")
        End If
        If CheckBox2.Checked = True Then
            SendKeys.Send(TextBox2.Text)
            SendKeys.Send("{Enter}")
        End If
        If CheckBox3.Checked = True Then
            SendKeys.Send(TextBox3.Text)
            SendKeys.Send("{Enter}")
        End If
        If CheckBox4.Checked = True Then
            SendKeys.Send(TextBox4.Text)
            SendKeys.Send("{Enter}")
        End If
    End Sub

I was see this not easy too so i made invisible label and used it to make 8 TextBoxs for my spammer in some billiard site
any ways
Timer :

Sendkeys.send(textbox1.text) ' first it will start text box without ''If'' System
sendkeys.send"{enter}"
Label1.text "1" 'We finish thing
If Label1.Text = "1" Then
Sendkeys.send(textbox2.text) ' see.. we will use the label for make multi spammer [more than 1 textbox] ;)
Sendkeys.send"{enter}"
Label1.text = "2"
If Label1.Text = "1" Then
Sendkeys.send(textbox2.text
Sendkeys.send"{enter}"
Label1.text = "3"

You can make many text boxs as you need
