• SQL Server Receiving messages in a Message Queue

  I am new to message queues, so please excuse my ignorance... but when I set a Message Queue as a receive queue... shouldn't it poll for each message in the queue It is running once and I am receiving the value within that queue, but then it just finishes with success. I have tried created a For Each container around it, but that just jumbles the whole mess of it. I have tried various options, but am currently using the "String message to variable" option. Any help would be greatly appreciated. I would really like to delve into transferring more interesting objects, but will settle for just strings at this point. If there ar ...Show All

• Windows Forms Directory Browsing in c#

  Hi, I am new C# user. My question is is there a a class in C# which allows me to browse directories. All I can see is a file save as and file open dialoag box. Thanks FolderBrowserDialog is a generic Folder Browsing Dialog that is available in 2.0 and 1.1 It's not very intuitive and extremely difficult to Navigate.

• .NET Development How to using datatable to create a table in DBMS?

  How to using datatable to create a table in DBMS there is a difference between datatables and tables in DBMS. Datatables are in memory representation of data, they contain columns & rows, while Tables in DBMS are in the DB. The typical way to use datatables is loading data from the database (table) to the datatable and manipultating the data the way you like, then apply the changes back to the database (table). ...Show All

• Visual C# How important are Assert-statements in C# compared to C/C++?

  Someone suggested that I should have Assert-statements at the very beginning of every method to check that the values of the in-parameters were in bounds (e.g. 0 <= x < 50) and not null if they shouldn't be. The suggestion were made mainly for C/C++. Is it relevant even for C# How important are Trace.Assert(), Debug.Assert() in C# compared to C/C++ Apparently Assert is one of those things that people either use, and suggest others use, or that people hate and often discourage others from using it... You should use Assert with code where you cant anticipate some breaking event. Validate the input th ...Show All

• .NET Development Why is System.Net not available in my add reference list?

  Subject pretty much says it all. I'm using Visual Studio 2005 C# Express. I went to add a reference to System.Net and System.Net.Sockets, but they simply aren't there. I tried reinstalling/repairing the SDK, but to no avail. I can't find any reference to this problem by googling it. I'm completely confused as to why this namespace isn't present. All work is halted until this issue is solved, so any help would be greatly appreciated! Thanks, Jason Catalyst OMG, I'm a retard. The example I was following said TCPClient, but it's TcpClient. Lesson learned... check spelling, then check case. :/ - Jason ...Show All

• Visual Studio 2008 (Pre-release) Recursion Bug in ServiceBehaviorAttribute

  We require implementing a predefined WSDL, and therefore must ensure the WCF generated WSDL is logically equivalent. The targetNamespace attribute of the wsdl:definitions element can only be set using ServiceBehaviorAttribute( Namespace = "myTargetNamespace" ). Unfortunately, the FebCTP has a bug in the Namespace property setter, where it recursively calls itself creating a stack overflow. Is there any workaround to this The RC0 of WCF will be released in a week or two. Check if the problem remains. Guy http://blogs.microsoft.co.il/blogs/bursteg/ ...Show All

• Visual Studio Team System How could I add a Setup or a TearDown procedure in the xxx.webtest?

  How can I add a Setup or a Teardown procedure in the xxx.webtest, not in the xxxCoded.cs I want to prepare some test data for xxx.webtest before it is run and cleanup this test data after the test is done. But I don't want to do it in the xxxCoded.cs because it will be overwritten once the xxx.webtest is modified.

• Visual Studio Express Editions Not necessarily "Express" Related, but what about WinMX

  With the cnahge from VB 6 to .NET 1, now .NET2, are we going to have to learn all over again to program under WinFX I'm just now getting my bearings in VB2005 (from VB5 Pro), will this be obsolete in a few months as well Am I misunderstanding the concept First of all, it's not VB.NET anymore it's just VB8 or VB2005. I think Microsoft is laying down a very solid foundation so that obsolescense will be OS related calls but not the structure of the language itself. On the other hand, I've seen previews of the functionality of the next version of Basic and if you think that is at all abs ...Show All

• SQL Server ETL from multiple Access databases -SSIS?

  Howdy Folks, I have an ETL project that I want to ask a question about. I want to loop through a folder containing several Access databases, and extract and load each one into a single SQL Server 2005 database. The table layout is the same for all the Access dbs, as well as the SQL db. The number of Access dbs in the folder, their records, and their names will change. Is there a way i can use the SSIS Foreach tool to move through the folder and set the connection string inside the loop Thanks for your reply, Chris Yes, you can do this.
