Hosting Office in .NET applications

  • Article

If you are building a .NET application and you are struggling to find a way to host Word documents, Excel spreadsheets, Visio drawings, Project files, or PowerPoint presentations, you might consider using the Visual C++ ActiveX Control for hosting Office documents. I learned about this download resource and I was shocked to see how you can add it to your solution and start working with Office applications in less than a minute. You can open Office applications, format content, update documents, save changes, print, and more inside your application. The Office Framer Control is an Active X control written in C++. The download includes source code to extend the functionality and sample code to use it inside Visual Basic 6 and HTML pages. You can also enable and disable specific functionality by using a full set of properties, methods, and events exposed for customization.

You can also host the control inside managed applications following these simple steps:

  1. Download and install the Office Framer Control 1.2 Sample.
  2. Start Visual Studio .NET. 
  3. Open your WinForms or WebForms application.
  4. Add the DSO Framer Control to the Toolbox: 
    • On the Tools menu, click Customize Toolbox (in Visual Studio .NET 2002), or click Add/Remove Toolbox Items (in Visual Studio .NET 2003), and then click the COM Components tab. 
    • On the COM Components tab, select DSO Framer Control Object. 
    • Click OK to close the Customize Toolbox dialog box.
  5. Select the DSO Framer Control icon that appears in the ToolBox and drag-and-drop the control over the Form or Web Form.
  6. Adjust the control’s docking/size as needed.
  7. Build and run the application.
  8. Create a new document to test the control.

I have to warn you that the control is not supported, the control and the source code is provided AS-IS for customization. However, you still can extend the functionality and it does the job, so have a peek and enjoy!

    Hello Erika! I am writing to you from Portugal. I'm a Microsoft Application Developer and I own a small ISV company and I develop many applications that integrate with Office (especialy in VB6 and VBA). I have been a developer for .NET since the first versions ou VS.NET and now I am developing integration with Office using .NET instead of VB6. I have to say that I found your blog very usefull and this tool here (DSO Framer Control) is realy cool. I'm going to explore it a little bit more. Thanks!

    I am porting an MFC application to .NET using C#.  The app has the feature of establishing OLE Link with Excel.  For example, user can copy a cell from Excel 2003 and do "Paste Link" to the app, and these 2 become linked together through OLE Link.

    I could not find anything on the internet do enable me to do that in C# and .NET.  Will this control help on this issue?

    Also I just heard about VS Tools for Office but have not tried it.  Does VSTO offer any help in this issue?

    Thank you in advance for any input.

    You can install it in the 2005 toolbox. Pretty tricky though. Furthermore... is you do a lot of calls I get timing issues with the Excel COM. I haven't found a way to time the threads yet.

    Hi, many people are asking about adding DSO framer into VS2005 toolbox. Does anyone have a reply for this, as I have not managed either.  When adding the DSO framer to the toolbox (VS2005) the control appears disabled, and I am not able to use it. Any ideas?  The same thing happens when adding the Visio Drawing Control to the toolbox in VS2005

    I developed an application with VB 2005. I'm using dsoframer control in the application to host MS Word document. I have no problem to load the word doc inside the dsoframer. But the problem is every time i click on the Print Preview button to preview the document and then close the print preview screen, the loaded document become a blank document inside dsoframer. In other word, the content on the document is gone! Then i tried to click on the Print preview button again, i found out that the content is still there under the preview mode. But i wonder why when i clicked on the close print preview, the content of the document is gone?? Can anybody tells me why and how to fix this? Thanks in advanced...

    I have tried to download the control from the page listed above (http://support.microsoft.com/default.aspx?scid=kb;en-us;311765) but I get an error when i try to run the exe.  The error message states the file is not a valid win32 application.  Is there another download place?  Is anyone else having this problem?? Thank you, zh

    Got this control to work relatively well using VB.NET after starting to play with the FramehookPolicy and ActivationPolicy properties. Stil another problem remains... when loading MsProject and opening the "Task Information" dialog, it appears it does not recieve some of the messages (e.g. cannot change fields in it). Anybody out there with some suggestions? Shall be much appreciated. Regards.

    I have found this to be an amazing tool. It is working quite well for what I need. However, when I close an xlsm file from the code-behind, I get an error when trying to reopen the document. Any feedback would be highly appreciated. Email: paul.moura@sgs.com
