My error is:

Code:

An unhandled exception of type 'System.IO.FileNotFoundException' occurred in System.Windows.Forms.dll

Additional information: Could not load file or assembly 'TCtrl Connection, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.

My source is:

Code:

Imports Admin_Tool_4s
Public Class Form2
    Dim TCTRLCon As Connection

    Private Sub Button8_Click(sender As Object, e As EventArgs) Handles Button8.Click
        TCTRLCon.Kick(TextBox1.Text)
    End Sub

    Private Sub Form2_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        TCTRLCon = New Connection("#", #)
        TCTRLCon.Connect()
