• Visual C# how the overriding mechanism happening?

  Hi all, I would like to know that how the overriding mechanizm happening . I know the concept but while compiling i would like to know that what is the mechanizm used behind that . thanks Gomaz Let's say we have 2 classes A and B: class A { public virtual void Func() {} } class B : A { public override void Func() {} } Each instance of class A and B will have a hidden pointer to an array of pointers to functions called Virtual Function Table (usually acronymed as VTBL). Since in our example we only have one virtual function the array will only have one entry and this is the pointer to Func. When an instance of class A is created, its VTBL will be initialized with the address of function ...Show All

• Visual C# naming convention: _property vs. this.property

  private string _property; public string Property { get { return _property; } set { _property = value; } } private string property; public string Property { get { return this.property; } set { this.property = value; } } Is there a design guideline on how to name fields that are encapsulated by a property Wich of those two versions should be preferred and why In the 2nd version FXCop complains that Member names should never differ only by case. But most code I see seems to prefer the 2nd version ... If you look at the guidelines for field usage, you see the usage of camelCasing for private fields and PascalCasing for public fields and properties. However, going through the .NET Framework documentation you will see num ...Show All

• Visual Studio Team System Two questions on Team Builds

  Q1: How I can delete build from TeamBuildTypes folder I guess I can't edit build in visual editor after it's created... Never mind - I found the answer on this one (Version Control is micromanaging...) Q2: When I am running through Create Build Wizard - as soon as I get to the options it won't let me proceed untill I uncheck "Run tests" checkbox. Why It allows me select proper test metafile but I can't see anything or edit in test list listbox and Next button is disabled... Ok, here is my vsmdi file - what should I look for < xml version="1.0" encoding="utf-8" > <Tests> <edtdocversion branch="retail" build="50727" revision="42" /> & ...Show All

• Software Development for Windows Vista TransactionScope committing without being told to!

  I ran into a huge problem using TransactionScope. I've been using it inside some classes that manage persistence to a database. I intended to use System.Transactions so that calling classes can wrap my persistence manager classes in a transaction scope and thereby control whenther or not a transaction commits or not. The persistence manager is blissfully unaware that the transaction it uses internally is being controlled by an external transaction scope. Here's an example of my problem: public void Test() { string conString = "Data Source=localhost;" ; SqlConnection con = new SqlConnection (conString); con.Open(); this .DoDatabaseStuff(con); con.Close(); } public void DoDatabaseStuff( SqlConnection con) ...Show All

• SQL Server Merge Replication between two servers not connected via internet and on two separate domains

  I have two sql server 2000 databases and I wish to do merge replication between them, the problem is that they are not connected via the internet (no ping) and are on two separate domains in different countries. I can use email and I can use encrypted ftp. I am wondering if I could use sql ce merge replication to a pocket pc which creates an sdf file, that I then email backwards and forwards and build identical publication and subscriptions at either server to merge sync with this sdf file through a pocket pc. Has anyone done this before Does anyone have any other suggestions It's not going to be possible. Merge replication is built with partners that can publish/subscribe to each other. If all you have is email/ftp, yo ...Show All

• Software Development for Windows Vista [RTM Vista] - Problem binding an ssl certificate to an ip:port, nothing works :-(

  Look this link. I'm running on Windows Vista RTM as an administrator. The certificate has been crafted with makecert for developing purposes. I'm getting error 1312 while registering it to whatever ip/port. I need this certificate to authenticate a WCF metadata exchange through https. I tried to logon myself using "net use" but nothing seem to happen even when "net session" command states a session actually exists. I'm getting confused since i should be already logged -_- as an administrator. I'm googling around, i've found other ppl posting on forums they're experiencing the same problem without solutions.

• Game Technologies: DirectX, XNA, XACT, etc. How do I load a 3d mesh (.x file)?

  How do I load a .x mesh into my scene The space game seems to use its own format (which it names .swm), and there's nothing in the help. I've been scanning through through the classes in the Framework namespace, but I can't see anything obvious! Is .x the recommended format for objects like this (If not, I change my question to be about the recommended format :D) If anyone knows anywhere that has some nice .x meshes I can play with, that'd be cool too. The only one I have lying around is a chair, and that's going to look a bit funny running around my game :D I didn't think the content pipeline stuff was in the beta I just added this code, which compiles: ContentManager contentManager = new ...Show All

• Visual Basic How do you list the fields of a database in a combobox?

  Hi, I was wondering what would be the easiest way to list all the fields that are in a database with a combobox I'm using VB .net 2005. All the fields in a database. I would assume you would be looking at fields in a specific table in a database. A database can contain many fields in many tables and views and displaying them all in a combobox would be rather nonsensical. You need to know which field is associated with which table. Hence being a bit more specific and showing the fields associated with a table in a database or using a control like a listview .datagridview to show more information on each field such as the associated table etc. ...Show All
