ReadMe

You will need the .NET CF 2.0

This DLL adds MultiTouch-Support to your existing .NET CF software very easily (Currently only for the HD2):

First of all you will have to add your app to the PinchToZoom Whitelist in the registry:
   [HKEY_LOCAL_MACHINE\Software\HTC\TouchGL\Pinch\WhiteList\YourApp]
   "ProcName"="YouAppProcessName.exe"
After adding, soft reset!

Then add the "SciLors-MultiTouch.dll" as reference in your Visual Studio project. Beware, it is not allowed to change the assembly name! It must stay "SciLors-MultiTouch.dll" or it will not work!

Afterwards declare the MultiTouch Class:
   VB.NET:
      Dim myMultiTouch As New SciLorsMultiTouch.SciLorsMultiTouch

   C#:
      SciLorsMultiTouch.SciLorsMultiTouch myMultiTouch = new SciLorsMultiTouch.SciLorsMultiTouch();

Then you add following to your Form_Load event:
   VB.NET:
      Call myMultiTouch.CatchWndProc(Me)
      AddHandler myMultiTouch.MouseDown, AddressOf frmMain_MouseDown
      AddHandler myMultiTouch.MouseMove, AddressOf frmMain_MouseMove
      AddHandler myMultiTouch.MouseUp, AddressOf frmMain_MouseUp

   C#:
      myMultiTouch.CatchWndProc(this);
      myMultiTouch.MouseDown += frmMain_MouseDown;
      myMultiTouch.MouseMove += frmMain_MouseMove;
      myMultiTouch.MouseUp += frmMain_MouseUp;

Now, at every MultiTouch Event it gets delegated to your frmMain_Mouse* procedures (There will be always 2 Events fired due to there existing 2 Fingers on the screen ;) ). You can easily detect wheather the mouse event comes from a normal mouse-press or a multitouch finger.
   Single Finger:
      Windows.Forms.MouseButtons.None or MouseButton = Windows.Forms.MouseButtons.Left
   MultiTouch:
      Finger 1: Windows.Forms.MouseButtons.Middle
      Finger 2: Windows.Forms.MouseButtons.Right

Code Examples:
   VB.NET:
      Public Structure MouseState
         Dim Position As Point
         Dim MouseDown As Boolean
      End Structure

      Public Fingers(2) As MouseState

      Public Sub frmMain_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles frmMain.MouseDown
         Dim ButtonID As Byte = ButtonToID(e.Button)
         With Fingers(ButtonID)
            .Position.X = e.X
            .Position.Y = e.Y
            .MouseDown = True
         End With
      End Sub

      Public Sub frmMain_MouseMoveByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles frmMain.MouseMove
         Dim ButtonID As Byte = ButtonToID(e.Button)
         With Fingers(ButtonID)
            .Position.X = e.X
            .Position.Y = e.Y
            .MouseDown = True
         End With
      End Sub

      Public Sub frmMain_MouseUp(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles frmMain.MouseUp
         Dim ButtonID As Byte = ButtonToID(e.Button)
         With Fingers(ButtonID)
            .Position.X = e.X
            .Position.Y = e.Y
            .MouseDown = False
         End With
      End Sub

      Private Function ButtonToID(ByVal MouseButton As MouseButtons)
         If MouseButton = Windows.Forms.MouseButtons.None Or MouseButton = Windows.Forms.MouseButtons.Left Then
            Return 0
         ElseIf MouseButton = Windows.Forms.MouseButtons.Middle Then
            Return 1
         Else
            Return 2
         End If
      End Function

   C#:
      public struct MouseState
      {
         public Point Position;
         public bool MouseDown;
      }
      public MouseState[] Fingers = new MouseState[3];

      public void pctDraw_MouseDown(object sender, MouseEventArgs e)
      {
         int ButtonID = Conversions.ToByte(this.ButtonToID(e.Button));
         this.Fingers[ButtonID].Position.X = e.X;
         this.Fingers[ButtonID].Position.Y = e.Y;
         this.Fingers[ButtonID].MouseDown = true;
      }

      public void pctDraw_MouseMove(object sender, MouseEventArgs e)
      {
         int ButtonID = Conversions.ToByte(this.ButtonToID(e.Button));
         this.Fingers[ButtonID].Position.X = e.X;
         this.Fingers[ButtonID].Position.Y = e.Y;
         this.Fingers[ButtonID].MouseDown = true;
      }

      public void pctDraw_MouseUp(object sender, MouseEventArgs e)
      {
         int ButtonID = Conversions.ToByte(this.ButtonToID(e.Button));
         this.Fingers[ButtonID].Position.X = e.X;
         this.Fingers[ButtonID].Position.Y = e.Y;
         this.Fingers[ButtonID].MouseDown = false;
      }

      private object ButtonToID(MouseButtons MouseButton)
      {
         if ((MouseButton == MouseButtons.None) | (MouseButton == MouseButtons.Left))
         {
            return 0;
         }
         if (MouseButton == MouseButtons.Middle)
         {
            return 1;
         }
         return 2;
      }

Function Description/Documentation:
-CatchWndProc(myForm, Optional PositionFixX, Optional PositionFixY): Redirects the Windows Messages from the "myForm" to the Multitouch Class. If you want to use it for a Control on top of the Form, the PositionFix can add/remove constant values to the returned MouseMessages.
-RestoreWndProc(): Detaches the Multitouch Class from the Form to restore the normal Window Message flow.
-UpdatePositionFix(PositionFixX, PositionFixY): If your control has changed it's position you can change its position in the class
-UpdateFormTopLeft(PositionFixLeft, PositionFixTop): If the Top-Left Corner of the Form changes you may use this.
-GetInformation(): Gives a Information String of the Multitouch DLL. It includes the version and some contact information.

ToDo:

Additional:
-Multiple Instances are not supported and not needed (Multitouch events fire allways, everywhere on the form)!
-The Mouse-Coordinates are allways relative to the forms top-left corner.
