Since lately the Visual Studio Tools For Office 2012 (VSTO 2012) are available for download . Can this new version still used for developing Add-In solutions for older Office versions (2007,2010)? Are there any advantages over VSTO 4.0 (besides Office 2013 support) Yes, it can. I'm using VS2012 for an Excel 2007 project and it works fine. The trick is to change the debug path in your project file so that VS uses the older version of the Office app your plugin is for. Create your VSTO project (let VS create the project for Office 2010) Edit the project file and find the <ProjectProperties> with

I'm following this example to create a custom rightclick custom menu for an excel add-in with VSTO and display it under certain conditions (rightclick inside a range of an Excel named table). My modified version of the code from the example works like a charm when I right click outside a named table range: but it doesn't get displayed when you right click inside a named table range: I suppose it has something to do with the Quick Analysis functionality interfering with my custom context menu overrides. Here is the code I'm using inside ThisAddin.cs: void Application_SheetBeforeRightClick

Update: I had a question below but actually my problem would be solved by asking a slightly different question. Why on some machines does my application throw the error: Configuration system failed to initialize - System.Configuration - at System.Configuration.ConfigurationManager.PrepareConfigSystem() where as on other machines it does not. The error as described also here .NET 3.5 - Configuration system failed to initialize exception is caused by a missing configSections element at the top of my app.config. Of course, the problem would be resolved by putting this section in but for some

I would like to add a new section to the To-Do Bar in Outlook 2010 (or 2007). I found some code to create a new collapsible task pane and someone claiming you can't modify the To-Do bar, but I also found a product called Add-In Express that claims it can do it (although at $349 it's not worth it for a one-off project). Is is possible to do that? After some research (and after having seen the product documentation of Add-in Express), I figured that it is possible to customize the To-Do Bar in Outlook 2007. There is a proof-poof-concept on CodeProject that embeds a "custom" (read self-written)

Given: A VSTO Add-In An override object RequestComAddInAutomationService() which returns an instance of a class which is called Facade in my scenario. A VBA macro in Excel 2007 which accesses the AddIn.Object to get the Facade and uses it. A plenty of times where this works perfectly fine. A couple of times where out of the blue, this doesn't seem to work. Update: Turns out that it's a particular user that has the problem. She has it all the time, others never have it (? never say "never") In this "couple of times" I get Error: Object variable or With block variable not set at the line of code
