问题 When I install my VSTO-based PowerPoint plugin, it always shows up in the 'disabled' section and everytime I open PowerPoint - I have to manually enable it. How do I programmatically change this behaviour such that plugin is always enabled by default. 回答1: When you set an Office (VSTO) addin to be enabled (in Office), it changes the registry key: HKLM\SOFTWARE\Microsoft\Office\PowerPoint\Addins\YourAssemblyName "LoadBehavior" The LoadBehavior value must be set to 3 to load (ie enabled) (2 is

问题 As the headline suggests, what I'm trying to do is to embed a Cefsharp Chromium browser in a VSTO Custom Task Pane (CTP) for Excel.

问题 I'm making a Word 2007 add-in with C# 4.0 in Visual Studio 2010. I need an Access 2007 database (a .accdb file) to be placed in the data directory by the clickonce installer. Unfortunately, the file is getting put elsewhere, so the application can't find it at runtime. I've seen various articles refer to using the Application Files dialog on the Publish tab of the project properties to mark the file as a data file, but I have no Application Files button for some reason. Any idea how to make

问题 I saw an article on creating Excel UDFs in VSTO managed code, using VBA: http://blogs.msdn.com/pstubbs/archive/2004/12/31/344964.aspx.

问题 Is it possible to extract the content of an embedded OLE object in Microsoft Office using VBA/VSTO?

For instance, in Excel the object is accessible via ActiveSheet.Shapes(x).OLEFormat but I have not found a way to retrieve the raw data of the object. One way would be to open the native file (Office Open XML

问题 Our development team mostly works on the same terminal server. We are working on an Outlook VSTO 2010 addin. We just migrated from "Visual Studio 2008/Office 2003/VSTO 2005" to "Visual Studio 2010/Office 2010/VSTO 2010". Attempting to debug the Add-In from Visual Studio results in the following error if any other user is running Outlook on the server: Cannot debug the add-in because 'Outlook' is already running. Close 'Outlook' and then run the project again. Before the software update, each
