• .NET Development exception in socket .ctor()

  Hello, Sometimes, just sometimes, my socket code throws an exception with following message: "Socket operation on nonsocket" ...or something like that, I work on the polish language pack, so this is just a translation. Wierd thing is that this exception is thrown in the socket's constructor! A bit of code: using (Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Raw, ProtocolType.Icmp)) { // the exception is thrown in constructor! s.WhateverFunc1(); s.WhateverFunc2(); } What may cause such behaviour Some, perhaps helpful, information: - application runs on WinXPSP2 NET1.1SP1 Intel4HT (pseudo ...Show All

• Visual Studio Team System TF GET docs confusing

  The itemspec description says: Itemspec  File or folder to retrieve. If no itemspec is provided, Team Foundation performs a recursive get of the current workspace.   But then in an example later it says this: C:\projects> tf get /recursive  Retrieves the latest versions of all uncloaked items from the server folder and all of its subfolders to the C:\projects directory, creates working folders where necessary.

• Windows Forms I need documentation on how to create a patch

  We have just recently released and we know we will have to patch the product. So can anybody point me to some good documentation on how to create a patch. For the original product we used visual studio 2005 to create our install. I would also like to know how the patch interacts with the original install when it comes time to upgrade or uninstall the product. I believe the recommended way to update VS 2005 setups is the RemovePreviousVersions project property. The potential issue with generating patches is that the internals of the MSI files involved must be consistent in their treatment of the embedded cab ...Show All

• SQL Server Ignore Null in a Column that otherwise needs a Unique Value

  In Access, when you specify a unique key for a column, you can also specify IGNORE NULL, in which case there can be more than one record with NULL, but if the field is not NULL, then only one record can exist. How do I do the same thing in SQL Server. I have a table with a column that identifies a Previous Entry. If the column is Null, then there is no previous entry - this may occur often. If the column is not null, then there is a Previous Entry. A Previous Entry can be used only once. Much appreciate any guidance received. Thanks, Flavelle Steve: Now that I understand your solution (forgive the newbie), i ...Show All

• SQL Server Hierarchical table Functions Vs Hierarchical CTE

  Recently I was in need of a hierarchical tree data. I learned about CTE and how they can be used to build hierarchical data with simple syntax. I used CTE and was through with the task. Later during free time, I tried to compare CTE approach with the traditional SQL 2K Table Function approach. It was surprising to see the query costs when I ran both the modes at one go... Query Cost (relative to batch) : 0.49% Query Text : Select * From fn_GetTree(8); Query Cost (relative to batch) : 99.51% Query Text : with treedata (id, parentid, status, prevStatus, lvl) as (select ...) What does that indicate Does it mean that the Table Function ...Show All

• Visual Studio 2008 (Pre-release) "late binding" communication and more questions

  I have several more basic questions concerning indigo: 1. Does the WCF provide a way to communicate to a slick way to communicate to a web service which is discovered during runtime. As an example: somebody provides a WSDL and an operation he wants to call from this service as well as a XML message he sends to the service and a XSL that he wants to apply to the response message. Currently I do something like that with a manual HttpWebRequest. Is something like that possible with WCF in a better way or is the contract/a known interface a requirement for WCF communications 2. Is WCF supported on the Compact Framework or will it be 3. ...Show All
