Scaling form controls according to screen resolution - vb.net

Question

I am trying to write program in vb 2010 that is independent of screen resolution.
I am designing the program in 1920*1080 and when I change the resolution to e.g. 800*600 everything blows up and the program won't fit the screen. How can I fix this?
I have tried three different approaches:
loop through all controls and scale their position and dimensions
Friend Sub ResizeControl(ByRef ctl As Control)
'---------------------------- GET SCALES -------------------------
Dim DesignScreenWidth As Integer = 1920
Dim DesignScreenHeight As Integer = 1080
Dim CurrentScreenWidth As Integer = Screen.PrimaryScreen.Bounds.Width
Dim CurrentScreenHeight As Integer = Screen.PrimaryScreen.Bounds.Height
'Ratios
Dim ratioX As Double = CurrentScreenWidth / DesignScreenWidth ' e.g. 800/1920
Dim ratioY As Double = CurrentScreenHeight / DesignScreenHeight
With ctl
Dim height As Integer = Math.Min(.Height, CurrentScreenHeight)
Dim width As Integer = Math.Min(.Width, CurrentScreenWidth)
'Position
If (.GetType.GetProperty("Top").CanRead) Then .Top = CInt(.Top * ratioY)
If (.GetType.GetProperty("Left").CanRead) Then .Left = CInt(.Left * ratioX)
'Size
If (.GetType.GetProperty("Width").CanRead) Then .Width = CInt(width * ratioX)
If (.GetType.GetProperty("Height").CanRead) Then .Height = CInt(height * ratioY)
End With
'---------------------- RESIZE SUB CONTROLS -------------------------------
For Each subCtl As Control In ctl.Controls
ResizeControl(subCtl)
Next subCtl
End Sub
Anchor each control to the main Form and only resize the main form
tried to AutoScale Mode
Dim factorX As Double = ratioX * 96.0F
Dim factorY As Double = ratioY * 96.0F
Dim newSize As SizeF = New SizeF(factorX, factorY)
AutoScaleDimensions = newSize
AutoScaleMode = AutoScaleMode.Dpi
Scale(newSize)
Font = New Font(Font.FontFamily, Font.Size * factorX)
None of these methods has worked for me. What am I doing wrong?
One thing I figured out was that my main form is larger than 800*600 pixels so when I run the designer in 800*600 resolution VS cut down the with to 812px so my calculations of with and thus scaling ratio becomes wrong. This error goes applies for all three methods.
Please advise on the best method and if I am doing something wrong.

As an expansion to my first comment, take a look at some best practices from the UX (user experience) world. There is a lot of science and and deliberation put into UIs that work.
There's a great SE site - ux.stackexchange.com that you may find can answer your questsions better than SO.
Here's some questions you may find helpful:

Responsive web design seems to parallel what you're doing. The idea behind it is to have your website be able to handle any client device - which is becoming very important because of the mobile explosion.
I suggest doing some studying in these areas to come up with a good solution.
