Connect a tool embedded in a Windows Form

[GorkemTolan]

I'm trying to get x and y coordinates from the map when I click it. The mousedown event is initialized by the button(tool) which is embedded in a windows form. The windows form resides in the ArcMap application. The problem is initializing (activating) the mouse down event by the windows button. Any suggestions would be great. 

Here is the windows button click event:

Private Sub btnMapSelection_Click(sender As System.Object, e As System.EventArgs) Handles btnMapSelection.Click

        Dim pTool As New CoordinateSelectorTool

        pTool.OnCreate(_application)
        pTool.SetForm(Me)

        Me.Hide()
        Dim UIDCls As ESRI.ArcGIS.esriSystem.IUID = New ESRI.ArcGIS.esriSystem.UIDClass
        UIDCls.Value = "CTM.GIS.GISDesktop.CoordinateSelectorTool"
        Dim commandItem As ESRI.ArcGIS.Framework.ICommandItem = _application.Document.CommandBars.Find(UIDCls)

        If commandItem Is Nothing Then
            Exit Sub
        End If

        _application.CurrentTool = commandItem
        '_application.CurrentTool = GetCommandItem("{94ea5994-2e62-44b7-8786-a0d0075e91e8}")
       
    End Sub


ArcObject Tool:
Public Overrides Sub OnMouseDown(ByVal Button As Integer, ByVal Shift As Integer, ByVal X As Integer, ByVal Y As Integer)

        Dim pMxDoc As IMxDocument
        pMxDoc = m_application.Document
        ClickPoint = pMxDoc.ActiveView.ScreenDisplay.DisplayTransformation.ToMapPoint(X, Y)
        'TODO: Add CoordinateSelectorTool.OnMouseDown implementation
    End Sub

This is how I've done it in one of my applications, a Desktop Add-in

The code in my window that contains several drawing options...a buffered point, a polygon, a rectangle, etc. I have another class DrawTool that handles the OnMouseDown action

   Private Sub Draw_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPoint.Click, btnPolygon.Click, btnFreehand.Click, btnRectangle.Click

        Dim pUID As New ESRI.ArcGIS.esriSystem.UID
        Dim pCommandItem As ESRI.ArcGIS.Framework.ICommandItem

        Try
            pUID.Value = My.ThisAddIn.IDs.DrawTool
            pCommandItem = m_application.Document.CommandBars.Find(pUID, False, False)

            Select Case sender.name
                Case "btnPoint"
                    'this contains code for specific actions for the point button
                Case "btnFreehand"
                     'this contains code for specific actions for the freehand button
            End Select
        
            Me.Visible = False
            m_application.CurrentTool = pCommandItem

        Catch ex As Exception
            System.Windows.Forms.MessageBox.Show(ex.ToString, "Open Draw Feature")
        End Try
    End Sub

This is the DrawTool class

Public Class DrawTool
    Inherits ESRI.ArcGIS.Desktop.AddIns.Tool

    Private graphicsContainer As ESRI.ArcGIS.Carto.IGraphicsContainer
    Private m_LineFeedback As ESRI.ArcGIS.Display.INewBezierCurveFeedback = Nothing

    Protected Overrides Sub OnMouseDown(ByVal arg As ESRI.ArcGIS.Desktop.AddIns.Tool.MouseEventArgs)
        MyBase.OnMouseDown(arg)

        Try
            Dim activeView As ESRI.ArcGIS.Carto.IActiveView = My.ArcMap.Document.ActiveView
            Dim pGeometry As ESRI.ArcGIS.Geometry.IGeometry5 = GetFeatureFromMouse(activeView, arg.X, arg.Y)
            Dim rgbColor As ESRI.ArcGIS.Display.IRgbColor = New ESRI.ArcGIS.Display.RgbColorClass()
            Dim FillStyle As ESRI.ArcGIS.Display.esriSimpleFillStyle


            rgbColor.Red = 255
            FillStyle = ESRI.ArcGIS.Display.esriSimpleFillStyle.esriSFSBackwardDiagonal


            If pGeometry Is Nothing Then Exit Sub

           AddGraphicToMap(pGeometry, rgbColor, rgbColor, FillStyle) 'this is the ArcGIS snippet "Add Graphic to Map"

        Catch ex As Exception
            System.Windows.Forms.MessageBox.Show(ex.ToString)
        Finally
            m_DrawFeature.Visible = True 'This is the form with the buttons
        End Try
    End Sub

        Dim pGeometry As ESRI.ArcGIS.Geometry.IGeometry5
        Dim pPolyLine As ESRI.ArcGIS.Geometry.IPolyline6

        Try

            Select Case Globals.DrawFeatureType
                Case "Point"
                    pRubberBand = New ESRI.ArcGIS.Display.RubberPoint

                    Return pGeometry
                Case "Freehand"
                    pPoint = activeView.ScreenDisplay.DisplayTransformation.ToMapPoint(XVal, YVal)
                    If m_LineFeedback Is Nothing Then
                        m_LineFeedback = New ESRI.ArcGIS.Display.NewBezierCurveFeedback
                        m_LineFeedback.Display = screenDisplay
                        m_LineFeedback.Start(pPoint)
                        Return Nothing
                    Else
                        pPolyLine = m_LineFeedback.Stop
                        m_LineFeedback = Nothing
                        pPolygon = CreatePolygonfromPolyline(pPolyLine)
                        Return pPolygon
                    End If
                Case Else
                    System.Windows.Forms.MessageBox.Show("Not coded yet")
                    Return Nothing
            End Select

        Catch ex As Exception
            System.Windows.Forms.MessageBox.Show(ex.ToString, "Get Feature")
            Return Nothing
        End Try

    End Function

    Private Function CreatePolygonfromPolyline(pPolyline As ESRI.ArcGIS.Geometry.IPolyline6) As ESRI.ArcGIS.Geometry.IPolygon4

        Try
            Dim pOutCollection As ESRI.ArcGIS.Geometry.IPointCollection4 = New ESRI.ArcGIS.Geometry.Polygon

Ken,
thank you for your answer. My tool is not add-in in ArcMap. Thus I can't get a reference to the tool.

Dim commandItem As ESRI.ArcGIS.Framework.ICommandItem = _application.Document.CommandBars.Find(UIDCls)

commandItem returns nothing. Therefore, I can not assign it to the application's current tool. Maybe I am missing something.
Thanks,

[KenBuja]

Have you tried using the actual GUID of your tool instead? As I understand, the tool has to be on a tollbar or menu somewhere to use the ProgID (CTM.GIS.GISDesktop.CoordinateSelectorTool)

UIDCls.Value =  "{" & yourClass.ClassId & "}"

[GorkemTolan]

Yes I tried with the classID and progID. Application can not find the tool.
Here is the tool cool. It's very generic. I think I don't register the class somewhere. Thanks,
