• Software Development for Windows Vista MIDI and high resolution timers on Vista

  Hi, Can anyone point me to the best suited technology to use, when I want to build a MIDI recording and playback application.

• Visual Studio Express Editions Problems compiling project in Visual C++ studio

  I recently downloaded Visual C++ Studio and when I try to compile my project, I get error messages such as these below.

• Game Technologies: DirectX, XNA, XACT, etc. Gamestate tutorial?

  Hi all! I am looking for a GameState tutorial for XNA. I searched this forum and found a nice tutorial on the subject. ( http://www.kalme.de/index.php option=com_content&task=category&sectionid=4&id=14&Itemid=26 ) Except that it's not using the XNA framework so there is alot of stuff in the tutorial that is already taken care of in XNA. If there is a tutorial about how to handle gamestates in XNA it would save me alot of time figureing it out by myself from the tutorial above. I am glad for all the advice I can get. Happy coding This article might be helpful. ...Show All

• .NET Development How to tell if query comes up with nothing

  Hey all, If I do a query to a SQL DB and it does not find a match, say for ID, then how do I know that so I can give the user a No File found message. Sorry, I know this is fundamental stuff but I used to program ASP and now learning .NET. I think it has something to do with EOD and BOF. Thanks Depending on what are you doing with result of the query. If you have a query that just check existance of a row in a table then as was explained by Mark, you should use ExecuteScalar method to see what will be return value of procedure. Procedure will be developed to return a value that will tell you what is the result. But if your procedure return row or rows of data, but before reading you want to c ...Show All

• Visual Studio Express Editions Database

  Hi I need to connect to an SQL database that is on a remote server. How can i do this in vb 2005 express As shakalama stated VB Express ID Support for databases other than Access and SQL Express are not supported.  As SQL Express is designed to be a local database only and remote connections are not supported out the box for this then Add New Datasource is only going to present you with Microsoft Access File or Microsoft SQL Server Database File (SQL Express). That said - you can write your code to access any database that is supported - so you could write code to access as SQL Server, Oracle Database, MySQL etc.    But you are not going to get the IDE support from the designers and wizards.  &n ...Show All

• .NET Development GetHashCode and Equals once again

  I do not see how GetHashCode() and Equals() can ever successfully be implemented given the guidelines. I am assuming that one of the guidelines, apart from the well-known one of two objects being equal ( Equals() ) returning the same hash code ( GetHashCode() ), is that GetHashCode can not change during the lifetime of an object. Given this assumption it appears to me that GetHashCode must either be implemented on a totally immutable class, or that it must only use immutable data members of a class. Since this is the case, the Equals() function must also depend on either a totally immutable class or only use immutable data members of a class. To me this need to rely only on immutable data in a class defeats the entire purpose of object eq ...Show All

• Visual Studio Team System Suggestion: Selectively deploy objects

  Hi, This is a feature request. I think it would be nice to be able to "switch off" an object from being included in the DBPro build. This way, you could include things in your project but that don't need to be deployed until a later date. I recognise tht this isn't as simple as just checking a boolean flag - there's the whole issue of checking dependancies and thus disabling those as well. Thoughts Comments -Jamie Hello Gert, I'm sorry, but I (and I think Jamie would agree) do not agree with your answer. That removing from build is possible was known before, the current state of VSTS4DBP (and as you are saying also the RTM) preclude the use of this method.
