What would be the best way to expose certain functionality in a Dotnet VSTO Excel add-in to VBA, without requiring the user to be a local administrator (i.e. no COM registration, no HttpListener )? Would it be possible to use Microsoft Message Queues from VBA? If I may interpret your question as broadly as "How do I expose functionality in a .Net assembly to Excel without COM registration" then an excellent solution is to use Excel's XLL interface. Basically one deploys an xll shim and an associated .Net dll. When the xll is loaded it reflects over the dll and exposes the functions therein to

I am using the following code to open the signed/unsigned Outlook messages and I display the content in WebBrowser control.

I'm developing add-in for Outlook 2013,I'm struggling with PR_INTERNET_MESSAGE_ID , I could easily get PR_INTERNET_MESSAGE_ID on archiving incoming mails, but it returns nothing on sending mail. Any help would be appreciated! Thank you! here is my code string PR_INTERNET_MESSAGE_ID = "http://schemas.microsoft.com/mapi/proptag/0x1035001F"; Microsoft.Office.Interop.Outlook.PropertyAccessor pal = mailItem.PropertyAccessor; string Internet_Message_Id = pal.GetProperty(PR_INTERNET_MESSAGE_ID).ToString(); That property is only sent after the message is sent. Exchange 2010/2013 sets that property for

I have an Excel VSTO Add-in that is not installing on one of my users machines. It installs fine on everyone else's machine so far (8 machines), but on this one specific machine it is giving the following error message. Customization could not be loaded because the application domain could not be created. ************** Exception Text ************** Microsoft.VisualStudio.Tools.Applications.Runtime.CannotCreateCustomizationDomainException: Customization could not be loaded because the application domain could not be created. ---> System.TypeLoadException: Could not load type 'System.AddIn

I created a visual studio excel workbook project which contains ThisWorkbook class and I then included a functions class so that I can create my own excel function. I am trying to write a value to a cell using c# through the use of the function. I can write to the excel cell through the function class but only by creating a new application/workbook. So everytime I use this excel function, it will open new instance of excel. Is there a way I can write to a cell in the current excel workbook that is already opened? You probably create a new Excel application, instead of connecting to the active

I've not been able to find a whole lot on this anywhere. Let me start by saying I don't want to use the old Windows Form. I want to add a new WPF Window to my outlook 2007 addin project in visual studio 2008. The WPF Window template however does not show up. I was following this tutorial: http://msdn.microsoft.com/en-us/library/bb410039.aspx , which even had a picture of how you could add a new wpf window to your outlook 2007 addin.
