The LINQ-to-DASL provider of the Office Interop API Extensions provides a very limited set of mappings between its query types and their associated DASL properties.  We didn't have the time to add them all and we didn't know which properties (besides...

When your LINQ-to-DASL queries do not return the results you expect, how do you determine where the problem is?  The issue could be that the query simply doesn't do what you expect.  For example, you could be querying the wrong DASL properties...

I received an email over the weekend asking why the following LINQ to DASL query threw an exception: Outlook. Folder folder = (Outlook. Folder )Application.Session.GetDefaultFolder(Outlook. OlDefaultFolders .olFolderCalendar); var appointments...

Now that the Office Interop API Extensions have been released , I thought I would post a complete walkthrough of a simple LINQ to DASL application. Let's start with my fictitious Outlook calendar: This calendar shows that I have four appointments...

One of the disadvantages of C# compared with VB is its lack of support for parameterized properties. Instead, parameterized properties in C# are exposed as normal method calls prefixed with "get_" and "set_". This is particularly apparent when working...

In my last post I talked about LINQ to DASL, a LINQ provider that converts query expressions into their DASL equivalent in order to efficiently filter item collections in Outlook. But LINQ to DASL solves only a very specific problem for one particular...

Quick, tell me what the following code does: Outlook. Folder folder = (Outlook. Folder ) this .Application.Session.GetDefaultFolder(Outlook. OlDefaultFolders .olFolderInbox); string subject = "VSTO" ; string filter = @"@SQL=(""urn:schemas...

I like VSTO. I like C#. What I don't like is having to write VSTO code in C# like: object fileName = "Test.docx" ; object missing = System.Reflection. Missing .Value; doc.SaveAs( ref fileName, ref missing, ref missing, ref missing, ref missing...

Yesterday I gave a presentation on VSTO at the third annual Portland Code Camp . I demonstrated an Outlook 2007 add-in that used Outlook Form Regions, WCF, and WPF to integrate Amazon.com Wish Lists with contact items. As my first public speaking event...
