Need to change properties of control with same name as string variable

Hello Experts,

1) I return a single string variable from a database. This string is the same as one of hundreds of winform controls on the page:
 
  examples:   "Button19", "Button78",  "Button32", "TextBox95", "Label2", etc

2) I want to alter a property for the control that has the same name. For example, if the returned string is "Button78", then I'd like to alter a property for the System.Windows.Forms.Button control named Button78.

  example: Button78.BackColor = Color.Blue

Can anyone please provide a routine to accomplish this?  I'm having trouble referencing or pointing to the desired control.

I have built a graphical representation of all the servers, switches, etc. in our server room. Each port was drawn as a small button. When I click any port button, I want the mating port (I get this button's name from the SQL database) to change color. I'm also using GDI+ to draw a line representing the connecting Cat5e wire between the two ports.

Thanks

Try...

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim ctlToFind As String = "Button1"
        Dim matches() As Control = Me.Controls.Find(ctlToFind, True)
        If matches.Length > 0 Then
            Dim ctl As Control = matches(0)
            ctl.BackColor = Color.Red
        End If
    End Sub
