Something like the following will test your QueryString to a string value.

If (Request.QueryString("MyString") == "hello") Then
    label1.Text = "Hello";
    label1.Visible = true;
Else
    label1.Visible = false;
End If

In your code, you had "'s around the true and false values. You don't need these.
