Is there a way to programmatically add a digital signature to a VBA Macro in a word document using C# or VB.Net? There are some similar questions asked already; however, none that I could find answer my question: How to programmatically remove the digital signature from VBA macros in Excel? Digital Signature for Excel Macro Unfortunately, there isn't an automation API for this in the VBA environment.

I am coding a website on witch users have to add reports (Word document's) and to make possible to view them I convert *.doc to *.pdf, and then displaying them throught pdf.js.

I want to use Microsoft.Office.Interop.Excel to pull some data out of an XLS file. I have Visual Studio 2010 and the Office Developer Tools installed. However, I am getting a COMException error at var app = new Application(); when the program runs. Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).

I want to make a PowerPoint add-in to show some small html+css component on each slide, and not by adding add-in every time I'm adding a new slide. What should I look for and could it be done with some office add-ins and commands APIs? In PowerPoint, the way to add content that's repeated on every slide is called Slide Master (View > Slide Master).
