WebDav To Validate A Mailbox Exists On An Exchange Server?
Aug 12, 20096 program to VB .NET 2008 that had code that used the CDO 1.21 DLL to validate if a mailbox entered existed on an Exchange server. I saw the one posting from Microsoft that states that CDO is not supported on the .NET Framework. As this is a client application, the article recommended using WebDav to interact with the Exchange Server.
View 2 RepliesUpgrade The Framework On The Server - When Run The .exe File From The Server,get A Runtime Error?
Jun 29, 2009I have several programs that I wrote in Visual Basic.net 2003 that I run from a server at work. We upgraded to Visual Studio 2008 recently and I converted my code to that version. I rebuilt the .exes and tried to run it from the server. It said I needed to upgrade the framework on the server, which I did. Now when I run the .exe file from the server I get a runtime error:
Runtime Error!
Program: d:...
This application has requested the Runtime to terminate it in an unusual way. Please contact the applicaiton's support team for more information.
These programs are very important to the day-to-day operations of the company I work for. I did backup the software before converting it, so we're running normally right now, but there are modifications and upgrades I need to make as soon as possible, but cannot due to the programs crashing when I run the on the server.
Entity Framework Context Not Working?
Oct 15, 2011I am trying to figure out Entity Framework but I keep running into issues with the context. I create my .edmx file and it works fine but when I try to declare my context on my pages Visual Studio will not find them. My .edmx file is called YCLModel.edmx and my connectionstring for it is YCLEntites.
I try to declare the context as:
Dim yclcontext as new YCLEntites
I have also tried going into design mode and dragging from the toolbox but when I select my named connection it gives me the following error:
The metadata specified in the connection string could not be loaded. Consider rebuilding the web project to build assemblies that may contain metadata. The following error(s) occurred: Unable to load the specified metadata resource.

View 4 RepliesC# - Getting Subject Line Of E-mail Using WebDAV And .NET
Jul 24, 2009I am trying to learn more about webDAV and .NET. I have written an app that needs to pull all e-mails from an inbox on the server. I need to load these e-mails into an object that has the following properties:
- From
- To
- Subject
- Body
[Code]....
Is there like a urn:schemas:httpmail:subject or something like that where I can pull the subject line out? this is the way that I have been told to interact with the Exchange server so if anyone can shed any light on how to modify the above code to add a subject node and WHY - I am sure I can figure out how to modify it further to meet my needs.
So just to be clear, my question is this:
How can I modify the above code snippet to also include the subject line of an e-mail pulled off an Exchange server?

View 1 RepliesWebDAV & Exchange 2003 - Works In Debug, Fails Without?
Sep 23, 2010I am writing some code in VB.Net under .NET 2.0 which interfaces with MS Exchange 2003.Because of the Exchange 2003 "requirement" I am forced to write this code using WEBDAV.The code itself is replicating, to some degree,a schedule management process.It's creating Appointments on the Exchange Server in response to inputs from the user and managing it's data internally in a SQL Server database.The problem situation is this: A new person is assigned to be in charge of a meeting. The requirement says the program should generate a meeting cancellation request to the person removed from the meeting (if such a person existed) and a meeting request sent to the new person.In the case of there being an existing person, what appears to happen is this:
The meeting cancellation request
gets sent Exchange barfs and returns status code 500 (internal server error) during the set of requests which send the meeting request to the new person.However! While debugging this particular scenario, it works just fine for me, if I step through the code in the Visual Studio debugger. Left to it's own devices, it fails every time.Just for yuk's sake, I added a Thread.Sleep(500) to the part after sending the cancellation request, and Exchange doesn't barf anymore...
So, my question! If adding a Thread.Sleep to the code causes this error to go away, a race condition is implied, no? But, my code is running under a web application and is a totally single threaded process, from start to finish. The web requests I am sending are all in synchronous mode so this shouldn't be a problem. [code]....
...but a lot of the implementation details are hidden here, as I wrote a set of classes to interface with Exchange WebDAV.
Sql Server - Derived Associations In .Net Entity Framework?
Aug 9, 2010I want to have a single table that represents a person and have a number of other tables (such as Student/Teacher) use the Person table to store information related to a person. Unfortunately the entity framework doesn't seem to like it when I try to add an association between the Student or Teacher class and I don't understand why. The Person table contains a column called ParentEntityID, which equals either a StudentEntityID or a TeacherEntityID. In an ideal world I would like to be able to reference the Person table by going Student.Person.FirstName instead of Student.Entity.Person1.FirstName. The error .Net returns when trying to connect the Student/Teacher table to the Person table is:
Error 3007: Problem in Mapping Fragments starting at lines 265, 289: Non-Primary-Key column(s) [ParentEntityID] are being mapped in both fragments to different conceptual side properties - data inconsistency is possible because the corresponding conceptual side properties can be independently modified.
The actual database I am working with is a bit more complicated and has a number of tables connected to the Entity table, which makes my object model pretty ambiguous and was hoping to be able to clean it up a bit by using the entity framework.I am using VB.Net 3.5 in a web application.
Update...In an attempt to internalize the different types of relationships I can form, I have been playing with this simple example and have come up with the following possibilities:And the reason why I cannot make an association between the Student and Address table is because that relationship is not enforced in the database. If I wanted an association between these two tables I would need to re-think the design of my database. Is that correct?
Excessive SQL Server Processes For Entity Framework Based Application
Jun 27, 2011We are currently developing a WPF/Entity-Framework based application.One of our requirements was to allow the user option to select which environment(testing, training, or production) they will connect to when logging in.Each connection option points to its own database.In order to do this we are creating new EF contexts in the following way:[code]We have made sure that all new contexts are being disposed of once its job is completed.The problem is this: when the users are using the application we are seeing hundreds of SQL Server processes in SQL Server's activity monitor. Some individual users have upwards of 30+ processes associated when using the app. Once the user shuts down the app the associated processes all disappear - but while the app is running these processes seem to stick around.

View 1 RepliesSql Server - Rolling Back Entity Framework Transaction, Cached Item Persist?
Aug 23, 2011I'm using an Entity Framework context, and sometimes would like to create a transaction so that the client can do multiple changes and then commit/rollback them all together.However, if many changes were made, and SaveChanges() was called multiple times, after which a rollback is called, entities that were commited already, will remain the way they were commited, and would not roll back.Here's how my transaction-relative functions look like:
Public Sub BeginTransaction()
Dim context = HttpContext.Current.GetObjectContext()
If Not context.Connection.State = ConnectionState.Open Then
context.Connection.Open()
End If

Not only does the test fail, but it also leave the ObjectContext in an unstable mode, because it still has invalid changes in it.

GetShortPathName Not Working On New 64-bit Server?
Apr 28, 2009I have established code that calls GetShortPathName to convert, say, "r: estlongname" to "r: estlo~1". It works fine with our old server, and at various user sites. We've just got a new 64-bit server and the code no longer works, ie it does nothing so my program carries on trying to use the long name (later on in the code this causes problems because it's trying to write a batch file to perform an unzip & other functions). Any ideas why GetShortPathName isn't working? We're a small software company with no specialised network admin.
The code uses this declaration: Declare Function GetShortPathName& Lib "kernel32" Alias "GetShortPathNameA" (ByVal lpszLongPath As String, ByVal lpszShortPath As String, ByVal cchBuffer As Long)

Working With CSV Field In SQL Server
Jan 19, 2011I am working on an application that pulls a field from a SQL Server table that has numeric values separated by commas, for example (1, 3, 4, 6). I need to load this field and somehow load it into a numeric array. However, I can't seem to come up with a good solution. Here is what I have tried:
Dim PagetoSign as Integer()
PageArray = Split(_DataRowView("PagestoSign"), ",")
Dim _PagetoSign As String = ""

However, I receive an error message when it enters the for each loop. I'm not married to this method if there is a more elegant way.

Jun 3, 2010If you try to access a password protected page it does a security check and redirects you if you are not logged in, retaining the URL (ie.

Formatting Currency (U.S) Not Working With Data From Sql Server Database?
Mar 25, 2012I have a code that binds the data from the database to textboxes. The problem is I want to make one of the textboxes Payment use a dollar sign.I tried formatting it as shown in the code below but only the first record gets formatted, the rest do not. When I click the next button, the dollar sign disappeared.
Here is a portion of the code:
bs = New BindingSource(ds, ds.Tables(0).TableName)
Me.txtPayment.DataBindings.Add("Text", bs, "Payment")
Me.txtPayment.Text = Format(CType(txtPayment.Text, Decimal), ("c"))
I have tried everything else I know, FormatCurrency but no luck.Payment is the name of the column in the database, the data type in SQL Server is Small Money.
