Once the base of the tutorial application is completed, you can extend it with Office support using the following steps:

1. First, you need to add a reference to the ImageGear for .NET Office Assembly.
   1. In the Solution Explorer, right-click on References, and choose Add Reference.
   2. Choose the Browse tab, navigate to "ImageGear for .NET v21\Bin" directory.
   3. Select ImageGear21.Formats.Office.dll, and click OK.

   You should now have the ImageGear21.Formats.Office assembly listed under References in the Solution Explorer.

   

2. Next, add the Office using statement. Open the code for Form1.vb by right-clicking on the form and clicking View Code. At the top of the code add the following statement:

   VB.NET Example	Copy Code
   Imports ImageGear.Formats.Office;

3. Add the following statements in Form1_Load method right after the ImGearCommonFormats.Initialize() call:

   VB.NET Example	Copy Code
   ' Add support for Word files ImGearFileFormats.Filters.Add(ImGearOffice.CreateWordFormat())

4. Under the File menu, add the Load Document menu item. Double-click it to create a handler.
5. Copy the code from the Load Page menu handler for the Load Document menu handler.
6. Add the following fields to Form1 class:

   VB.NET Example	Copy Code
   Private igDocument As ImGearDocument Private currPageNumber As Integer = -1

7. Add the following method to Form1 class:

   VB.NET Example	Copy Code
   Private Sub UpdateMainView() ImGearPageView1.Page = igPage ImGearPageView1.Update() End Sub

8. In LoadDocumentToolStripMenuItem_Click find the following code:

   VB.NET Example	Copy Code
   igPage = ImGearFileFormats.LoadPage(stream, 0)

   and replace it with:

   VB.NET Example	Copy Code
   igDocument = ImGearFileFormats.LoadDocument(stream, 0, -1) currPageNumber = 0 igPage = igDocument.Pages(currPageNumber) igPageDisplay = New ImGearPageDisplay() ImGearPageView1.Display = igPageDisplay

   Also replace the following code:

   VB.NET Example	Copy Code
   If Not igPage Is Nothing AndAlso Not igPage.DIB Is Nothing Then ' create a new page display igPageDisplay = New ImGearPageDisplay(igPage) ' associate the page display with the page view ImGearPageView1.Display = igPageDisplay ' cause the page view to repaint ImGearPageView1.Invalidate() End If

   with:

   VB.NET Example	Copy Code
   If Not igPage Is Nothing Then UpdateMainView() End If

9. To enable navigation between Office document pages do the following:
   1. Under the View menu, add ‘First Page’, ‘Previous Page’, ‘Next Page’, ‘Last Page’ menu items. Double-click them to create handlers.
   2. In FirstPageToolStripMenuItem_Click add the following code:

      VB.NET Example	Copy Code
      currPageNumber = 0 igPage = igDocument.Pages(currPageNumber) UpdateMainView()

   3. In PreviousPageToolStripMenuItem_Click add the following code:

      VB.NET Example	Copy Code
      If (currPageNumber - 1 >= 0) Then currPageNumber -= 1 igPage = igDocument.Pages(currPageNumber) UpdateMainView() End If

   4. In nextPageToolStripMenuItem_Click add the following code:

      VB.NET Example	Copy Code
      If (currPageNumber + 1 < igDocument.Pages.Count) Then currPageNumber += 1 igPage = igDocument.Pages(currPageNumber) UpdateMainView() End If

   5. In lastPageToolStripMenuItem_Click add the following code:

      VB.NET Example	Copy Code
      currPageNumber = igDocument.Pages.Count - 1 igPage = igDocument.Pages(currPageNumber) UpdateMainView()

Now you are ready to compile and run the finished application working with Office documents.
