Very simple way to move a form holding down mouse button

Charles henington, you can consider this as VB.NET. F5 is nothing but start debugging. You got my 5.

Public Class Form1
    Dim pastx, pasty, presentx, presenty, bt As Integer

    Sub moving()
        Dim xx, yy As Integer
        xx = presentx - pastx
        yy = presenty - pasty
        If bt Then 'set your condition: left btn or right btn or mid btn
            Me.Left = Me.Left + xx
            Me.Top = Me.Top + yy
        End If
    End Sub

    Private Sub Form1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseDown
        pastx = e.X
        pasty = e.Y
    End Sub

    Private Sub Form1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseMove
        presentx = e.X
        presenty = e.Y
        bt = e.Button
        moving()
    End Sub
End Class
