ShapeAppBasicMFC with Document Entry Point

In this sample, Melody modified the proxy to include an entry point for the CDocDrawing class (the CDocDrawing class was also modified to include events which become disassociated with ProxyGen- see this blog for related info on this bug) and the HostItemProvider to expose the CDocDrawing type.  Melody also created a template for document level add-ins and used the template to create a sample add-in, ShapeAppMFCDocAddIn1.  Here is a link to the sample: ShapeAppBasicMFC with DocEP

To use this sample:

1)      Remove the old proxy from the GAC by deleting or uninstalling C:\Windows\assembly\Proxy

2)      Remove any VSTA v 1 add-in assemblies by deleting %MyDocuments%\ShapeAppMFC

3)      Run the included setup file to register the host and updated templates (SetupShapeAppAdvancedMFC.js)

4)      Build the ShapeAppAdvancedMFC.sln solution, this includes the document level sample add-in.  This will register the updated proxy in the GAC and build the add-in assembly.

5)      Run the sample and notice the message box and shape added from the document level add-in.

Here are the changes Melody made to add this functionality:

1)      HostItemProvider

Unchanged code excluded

    internal class HostItemProvider : IHostItemProvider

    {

        public HostItemProvider(ShapeApp.Proxy.Application application)

        {

            //SUMMIT- add drawing level HIP

            //store the active drawing

            this.drawing = application.ActiveDrawing;

        }

        public object GetHostObject(Type primaryType, string primaryCookie)

        {

            //Check if primaryType is supported.

            else if (primaryType == typeof(ShapeApp.Proxy.CDrawingDoc))

            {

                //SUMMIT- add drawing level HIP

                // update the drawing to ensure the current active drawing is returned

                this.drawing = application.ActiveDrawing;

                return this.drawing;

            }

        }

        //SUMMIT- add drawing level HIP

        //store the active drawing

        private ShapeApp.Proxy.CDrawingDoc drawing;

}

2)      Proxy and descriptor file

Descriptor file:

  <Class originalFullyQualifiedName="ShapeApp.Proxy.CDrawingDoc" GUID="6CBD1873-21F4-4386-B9BA-62555B7BCC12" SourceInterfaceGUID="CB42B8DA-44B1-4AAA-AFCC-7AFF84A5A481" isExcluded="false" isAddInEntryPoint="true">

Proxy File:

    public partial class CDrawingDocEntryPoint : global::Microsoft.VisualStudio.Tools.Applications.Runtime.IExtendedEntryPoint

    {/*entry point class code*/}

3)      Template

AppAddIn.designer.xml:

hostitem:baseType="ShapeApp.Proxy.CDrawingDocEntryPoint"

misc changes to vstemplate file for updated project name and description

4)      Add-in

No code changes required based on updated template, here is the code from the add-in

        private void AppAddIn_Startup(object sender, EventArgs e)

        {

            System.Windows.Forms.MessageBox.Show("Document level add-in loaded");

            this.Shapes.Add(this.Application.AvailableShapes[0].Clone());

        }
