[GIS] MFC Dialog Application using ESRI ArcEngine 10.0

arcgis-enginearcobjectsdevelopment

I'm new to ESRI ArcObjects and I'm trying to create a basic MFC dialog application. I add the License and MapControl to the dialog resource. I compile and run the app, but I get the following runtime error:-

Could not bind to a valid ArcGIS installation.
CoCreateInstance of OLE control {D7EAD71E-B663-4DCE-82C7-AEE2793DF5F3} failed.

Result code: 0x80040111
Is the control is properly registered?
Warning: Resource items and Win32 Z-order lists are out of sync. Tab order may be not defined well.
MFCDlg2.exe has triggered a breakpoint

I have registered the OCX's and I can see them in the registry. I'm running Win7 (64 bit) and Visual Studio 2008.

Please can anyone help

Thanks.

Are you compiling as an x86 (32-bit) application? ArcObjects is 32-bit only, so your application must be as well.

ArcObjects – Steps to Build a Balloon Callout Using ArcEngine 10 in VS2010 with C#

There is a VBA sample in the ArcDesktop help How to add a balloon callout it should be possible to customize for ArcGIS Engine, Change so that you ues the ActiveView from your MapControl or PagelayoutControl.

Update, code that works in engine:

Private Sub AddBalloonCallout(ByVal activeView As IActiveView)
        Dim pTextElement As ITextElement
        Dim pElement As IElement
        Dim pPoint As IPoint
        Dim pCallout As ICallout
        Dim pTextSymbol As IFormattedTextSymbol
        Dim pGraphicsContainer As IGraphicsContainer
        Dim midX As Double, midY As Double

        'Create a new text element
        pTextElement = New TextElement
        pElement = CType(pTextElement, IElement) 'QI
        pTextElement.Text = "Text callout" & vbCrLf & "In the middle of the screen"

        'Position the new element on the active view's center point
        midX = (activeView.Extent.XMax + activeView.Extent.XMin) / 2
        midY = (activeView.Extent.YMax + activeView.Extent.YMin) / 2
        pPoint = New Point
        pPoint.PutCoords(midX, midY)
        pElement.Geometry = pPoint

        'Set the text element symbology to a default balloon callout
        pTextSymbol = New TextSymbol
        pCallout = New BalloonCallout
        pTextSymbol.Background = CType(pCallout, ITextBackground)
        'Use this formula to get a callout anchor point location
        pPoint.PutCoords(midX - activeView.Extent.Width / 4, midY + activeView.Extent.Width / 20)
        pCallout.AnchorPoint = pPoint
        pTextElement.Symbol = pTextSymbol

        'Add the element to the active view, either the focus Map or PageLayout
        pGraphicsContainer = CType(activeView, IGraphicsContainer)
        pGraphicsContainer.AddElement(pElement, 0)
        pElement.Activate(activeView.ScreenDisplay)

        'Flag the area of the new element for refreshing
        activeView.PartialRefresh(esriViewDrawPhase.esriViewGraphics, pElement, Nothing)
    End Sub

It's only available in Desktop and not Engine, according to the API documentation: IdentifyDialog CoClass
