11/05/2012

Using a ClickOnce post-deployment action, you can install document-level Office solutions, and then copy the document to the end user computer. This requires that you modify the application manifest, and re-sign both the application and the deployment manifests before installation.

Applies to: The information in this topic applies to document-level projects and application-level projects for Microsoft Office 2013 and Microsoft Office 2010. For more information, see Features Available by Office Application and Project Type.

This walkthrough illustrates the following tasks:

Creating an Office solution to deploy.
Implementing a post-deployment action that copies a document to the end user's desktop.
Modifying the application manifest of the Office solution to run the post-deployment action.
Re-signing the application and deployment manifests.

Note

Your computer might show different names or locations for some of the Visual Studio user interface elements in the following instructions. The Visual Studio edition that you have and the settings that you use determine these elements. For more information, see Visual Studio Settings.

Prerequisites

You need the following components to complete this walkthrough:

An edition of Visual Studio 2012 that includes the Microsoft Office developer tools. For more information, see Configuring a Computer to Develop Office Solutions.
Excel 2013 or Excel 2010.
A test computer.

Creating a New Project

First, create an Excel workbook project.

To create a new Excel project

Create an Excel document-level project. Name the project ExcelWorkbook, and save the project to the %USERPROFILE%\Documents\Visual Studio 2012\Projects directory. For more information, see How to: Create Office Projects in Visual Studio.

Visual Studio opens the new Excel workbook in the designer and adds the ExcelWorkbook project to Solution Explorer.

Creating a Class Library Project that Defines the Post-Deployment Action

You must define the post-deployment action in a separate class library. The post-deployment action performs copies the document to the end user computer.

To create a class library for the post-deployment action

In the File menu, point to Add, and then click New Project.
In the Add New Project dialog box, in the Installed Templates pane, click Windows.
In the Templates pane, click Class Library.
In the Name field, type FileCopyPDA, and then click OK.
In Solution Explorer, click FileCopyPDA.
On the Project menu, click Add Reference.

The Add Reference dialog box appears.
On the .NET tab, add references to Microsoft.VisualStudio.Tools.Applications.Runtime and Microsoft.VisualStudio.Tools.Applications.ServerDocument.

In the Class1 code file, add the following using or Imports statements to the top of the code file.

Imports Microsoft.VisualStudio.Tools.Applications.Deployment
Imports Microsoft.VisualStudio.Tools.Applications

using Microsoft.VisualStudio.Tools.Applications.Deployment;
using Microsoft.VisualStudio.Tools.Applications;
using System.IO;

Rename the class to FileCopyPDA, and then add the following code to the FileCopyPDA class. This code indicates that FileCopyPDA class inherits from IAddInPostDeploymentAction.
```
Public Class FileCopyPDA
    Implements IAddInPostDeploymentAction
```
```
public class FileCopyPDA : IAddInPostDeploymentAction
```

Add the following code to implement the IAddInPostDeploymentAction.Execute method. This code performs the following tasks:

Copies the Excel workbook file to the user's desktop if the solution is installed or updated.
Changes the _AssemblyLocation property from a relative path to a fully qualified path for the deployment manifest. This is done using the AddCustomization and RemoveCustomization methods.
Deletes the file if the solution is uninstalled.

Sub Execute(ByVal args As AddInPostDeploymentActionArgs) Implements IAddInPostDeploymentAction.Execute
    Dim dataDirectory As String = "Data\ExcelWorkbook.xlsx" 
    Dim file As String = "ExcelWorkbook.xlsx" 
    Dim sourcePath As String = args.AddInPath
    Dim deploymentManifestUri As Uri = args.ManifestLocation
    Dim destPath As String = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory)
    Dim sourceFile As String = System.IO.Path.Combine(sourcePath, dataDirectory)
    Dim destFile As String = System.IO.Path.Combine(destPath, file)

    Select Case args.InstallationStatus
        Case AddInInstallationStatus.InitialInstall, AddInInstallationStatus.Update
            System.IO.File.Copy(sourceFile, destFile)
            ServerDocument.RemoveCustomization(destFile)
            ServerDocument.AddCustomization(destFile, deploymentManifestUri)
            Exit Select 
        Case AddInInstallationStatus.Uninstall
            If System.IO.File.Exists(destFile) Then
                System.IO.File.Delete(destFile)
            End If 
            Exit Select 
    End Select 
End Sub

public void Execute(AddInPostDeploymentActionArgs args) 
{
    string dataDirectory = @"Data\ExcelWorkbook.xlsx";
    string file = @"ExcelWorkbook.xlsx";
    string sourcePath = args.AddInPath;
    Uri deploymentManifestUri = args.ManifestLocation;
    string destPath = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory);
    string sourceFile = System.IO.Path.Combine(sourcePath, dataDirectory);
    string destFile = System.IO.Path.Combine(destPath, file);

    switch (args.InstallationStatus)
    {
        case AddInInstallationStatus.InitialInstall:
        case AddInInstallationStatus.Update:
            File.Copy(sourceFile, destFile);
            ServerDocument.RemoveCustomization(destFile);
            ServerDocument.AddCustomization(destFile, deploymentManifestUri);
            break;
        case AddInInstallationStatus.Uninstall:
            if (File.Exists(destFile))
            {
                File.Delete(destFile);
            }
            break;
    }
}

Building and Publishing the Solution

Use the Publish Wizard or the Project Page to build and publish the Office solutions to your development computer.

To publish the Excel project

In Solution Explorer, right-click the FileCopyPDA project, and then click Build.
In Solution Explorer, right-click the ExcelWorkbook project, and then click Build.
In Solution Explorer, right-click the ExcelWorkbook project, and then click Add Reference.
In the Add Reference dialog box, click the Projects tab.
Click FileCopyPDA, and click OK.
In Solution Explorer, click the ExcelWorkbook project.
On the Project menu, click New Folder.
Type Data and press the Enter key.
In Solution Explorer, click the Data folder.
On the Project menu, click Add Existing Item.

Click ExcelWorkbook.xlsx, and click Add.
In Solution Explorer, click ExcelWorkbook.xlsx.

Note

If you modify this file later, make sure to update the file by adding the latest version of the file.
In the Properties window, change the Build Action property to Content, and the Copy to Output Directory property to Copy if newer.
Publish the ExcelWorkbook project to the c:\publish folder. For more information, see How to: Publish an Office Solution by Using ClickOnce.

Modifying the Application Manifest

Use the XML editor in Visual Studio to modify the application manifest to run the File Copy post-deployment action. The content of an application manifest is similar to a bill of materials, which lists the entire contents of a box; an application manifest lists all dependent and prerequisite assemblies. The application manifest for an Office solution also lists the assemblies that should be loaded by an Office application for application-level add-ins and document-level customizations.

To add the installation dependencies to the application manifest

Open the c:\publish directory through File Explorer.
Open the Application Files folder and then open the ExcelWorkbook_1_0_0_0 folder.
Open the ExcelWorkbook.dll.manifest file in a text editor.

Add following code after the </vstav3:update> element. For the class attribute of the <vstav3:entryPoint> element, use the following syntax: NamespaceName.ClassName. In this example, the namespace and class names are the same, so that the resulting entry point name is FileCopyPDA.FileCopyPDA.

<vstav3:postActions>
  <vstav3:postAction>
    <vstav3:entryPoint
      class="FileCopyPDA.FileCopyPDA">
      <assemblyIdentity
        name="FileCopyPDA"
        version="1.0.0.0"
        language="neutral"
        processorArchitecture="msil" />
    </vstav3:entryPoint>
    <vstav3:postActionData>
    </vstav3:postActionData>
  </vstav3:postAction>
</vstav3:postActions>

Re-signing the Manifests

The following procedure signs the application manifest and updates the deployment manifest. This ensures that tampered files are not installed on end user computers.

To re-sign the application and deployment manifests

Copy the ExcelWorkbook_TemporaryKey.pfx certificate file from the %USERPROFILE%\Documents\Visual Studio 2012\Projects\ExcelWorkbook\ExcelWorkbook solution directory into the c:\publish\Application Files\ExcelWorkbook_1_0_0_0 directory.
Open the Visual Studio command prompt.
Change to the c:\publish\Application Files\ExcelWorkbook_1_0_0_0 directory.
Sign the modified application manifest with the following command:
```
mage -sign ExcelWorkbook.dll.manifest -certfile ExcelWorkbook_TemporaryKey.pfx
```
The message "ExcelWorkbook.dll.manifest successfully signed" appears.
Change to the c:\publish directory.

Update and sign the deployment manifest with the following command:

mage -update ExcelWorkbook.vsto -appmanifest "Application Files\Ex
celWorkbook_1_0_0_0\ExcelWorkbook.dll.manifest" -certfile "Application Files\ExcelWorkbook_1_0_0_0\ExcelWorkbook_TemporaryKey.pfx"

The message "ExcelWorkbook.vsto successfully signed" appears.

Copy the ExcelWorkbook.vsto file to the c:\publish\Application Files\ExcelWorkbook_1_0_0_0 directory.

Testing the Post-Deployment Action

The following procedure ensures that the updated manifest installs the Excel workbook and copies the workbook to the end user's desktop.

To test the post-deployment action

Copy the c:\publish directory to a test computer.
Run the Setup.exe program, or if the prerequisites are already installed on the test computer, double-click the ExcelWorkbook.vsto deployment manifest.

The Microsoft Office Customization Installer appears.
Click Install.

The Microsoft Office Customization Installer dialog box shows the following message: "The Microsoft Office customization was successfully installed." The Excel workbook is copied to the end user's desktop.
Open the ExcelWorkbook.xlsx file from the desktop.
