Outlook Automation Type Casting?
Feb 26, 2009
When writing some Outlook code in VS2005, I came across a situation that, to me, does not make any sense. For reference, the version of Outlook running on this machine is Outlook 2003.The program I'm writing is designed to iterate through the emails in the inbox, to identify certain types of emails based on their subjects and bodies, and then to generate new emails based on the existing ones. However, the problem that I'm having is with simply iterating through the collection of items that comes from the Inbox folder. Specifically, what happens is that this line consistently fails on items that should be processed:
Current_Item = CType(The_Items.Item(Counter), Outlook.MailItem)

I'm automating some outlook functionality in a .NET app. It works great. I am compiling it and using v 12.0.0.0 of the Outlook Interop assembly. My code should work on any version of Outlook so it seems silly to have to bind it to a specific version. Is it possible to use reflection to do this instead of compiling a reference? Are the interop assemblies on PC's by default that have Office installed anyway or do I need to include them with my application?

I have a macro written in VB in Excel, which reads emails from Outlook. I would like to automatize this process, but everytime, when Excel wants to access the outlook, I have to give permition to do that, see http://apophis.wz.cz/permition.PNG (It's in czech, but you will see the point). Is there any way to give this permition for ever? Or for long time, such as 10 hours? (I can choose max. 10 minutes).

I was wondering if anyone knew a way to have vb extract an attachment from an outlook email and save it to a specified directory. What I have is a program that when a file (outlook attachment) is dropped onto the main form it saves that file to a specific directory. I have the following code which seems to work for anything other than Outlook (possibly because outlook's drag and drop feature is defined differently?):
Code:
Private Sub Form1_DragDrop(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles MyBase.DragDrop

I installed the API redist [URL] for Office 2010 (Office 2010 was already installed). Then I tried to use code from MSDN [URL] just to see how it worked. I included the code here, since it's short. At the top of the file:
Code:
Imports Outlook = Microsoft.Office.Interop.Outlook
... and in the class:
Code:
Private Sub SendSalesReport()
Dim mail As Outlook.MailItem = CType(Application.CreateItem( _
Outlook.OlItemType.olMailItem), Outlook.MailItem)
[code]....
Unfortunately, VS2010 balks at the very first line, not recognizing the namespace. What do I need to do?Oh, and I can't find Microsoft.Office.Interop.Outlook.dll anywhere, either. Shouldn't that have been installed?

The listing (see below) is now well commented by me. Can anybody please help concerning the damn annoying exceptions and stop me pulling my hair out.

I have an application, running multiple threads, and in many of these threads, Outlook is being called, some mails read, attachments downloaded, and then the outlook instance closed. But it is possible that there are a number of threads trying to do the same thing at the same time. There is of course a lock at the beginning and end of the process, so that no two threads try to access the outlook application at the same time.
"Sometimes" i get an error message : Creating an instance of the COM component with CLSID {0006F03A-0000-0000-C000-000000000046} from the IClassFactory failed due to the following error: 80010108

I have one question. i have seen some codes like:
Req = CType(System.Net.HttpWebRequest.Create("url"), Net.HttpWebRequest)
Is it really necessary to cast the same type, or is there a difference when its not casted.

I've got a piece of code in a project (MyProject) that contains early bound object from a referenced assembly (We'll call it CommonAssembly):

i was wondering if someone could give me the final explanation on what i might be doing wrong here.I spent a lot of time reading around the net and the forum about how to add Threading capabilities to a VB project.
Nos, i've got .NET 4 installed, and i've added the system.tsr and mscorlib.dll files as reference in, say, Excel 2007 (see screenshot).However, when i try to make a thread with anything as basic as "Dim Thread1 As System.Threading.Thread", i get a user-defined type not found error.Indeed, when i use the object browser to see what's in the System file, theres nothing remotely linked to any Threading, and in the mscorlib file, nothing under "Threading" either, just a few Thread related functions, but nothing defining a data type

I am using Access 2007 as an automation server for a custom form in Outlook 2007. I am trying to use the records in an Access table as a rowsource for a Outlook combobox. I have been debugging it quite a bit; I can tell that I successfully grab a recordset and can tell that they are the correct values. The only problem is when I try to add an item to my combobox (cboCategory).I checked the properties of the additem function and it expects a variant, so that's what I give it. However at runtime, it gives me a type mismatch error.
