• Visual C++ From C++ Multiple Inheritance to Interfaces.

  Hi,     I want to understand what was/were the problem(s) with c++ mutliple inheritance model except Diamond Problem . If we can solve the diamond problem with Scope Resolution operator and we can achieve inheritance and polymorphism, then why we need to introduce a new concept of Interface. I'm not against the interface concept, it is just that I truly want to understand Interface edge over c++ multiple inheritance model. what was/were problem(s) with this model. what can't be achieved by c++ multiple inheritance . Thanks. My guess is that single inheritance plus multiple interfaces was chosen for: 1. Simplicity. 2. To facilitate language interopera ...Show All

• Visual Basic mcisendstring x64

  Hello, I got a little problem. I would like to play sounds with my application. I tried already a lot of methods. I tried the mcisendstring method too. This works very well in 32 bit (x86 compile), but not in 64 bit (x64 compile). But why does this not work in x64. I've installed Windows XP x64 so normally it has to work.

• Visual Studio Team System More Warehouse problems

  After a TFS rebuild I am no longer able to process the OLAP cube.  Initially TFS (and SQL) was built on a server with Australian regional settings.  However the rebuild was done on a server that had default US regional settings.  I have since changed the default collation for the database server back to the Australian collation (to fix errors in comparing and merging files).  The warehouse is still not working though.  It seems like its something to do with date formats, although I am not 100% sure.  Aus date format is the same as British (ie DD/MM/YYYY), eg today is 06/04/2006.  The value of TfsWarehouse.Today.Date was "4/6/2006", we tried changing it to "6/4/2006" but it still returned the sam ...Show All

  I hope you can help me to solve my issue. I created an endpoint and have an application to consume the methods from endpoint. Every thing work fine when i use the Impersonation with specific user id and password. In other words i am using Authrentication method = windows and Impersonate = true, user id = "[DOMAIN\userid]" password = "password" in web.config. But this is not the way i want to use endpoints in my application. I want to make it work without any user id and password in Impersonate section of web.config.

In my .net application i am using proxy.Credentiats = Syst ...Show All

• .NET Development SMTP client timeout issue with addresses that include an underscore.

  I am using system.net.mail to send out notifications for signups. my problem is that it works just fine unless any of the email addressess entered have an underscore. Like foxone@hotmail.com will work just fine but fox_one@hotmail.com will timeout. Does anyone know what might be causing this. it shouldnt. I've done it and works fine over here. I would suggest, as silly as it sounds, to disable your anti virus software and see how that goes. If you can, try to increase the timeout limit as well of the smtp client object to double the time and see if it still times out. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Point sprites in XNA

  I was wondering if i would be possible to display point sprites (in 3D) using the BasicEffect When I specify the position and the texture, I see colored points where the sprites should be (really the size of pixels). I guess the BasicEffect doesn't support point sprites, but because I cannot find the PointScaleA-C renderstates in XNA, I still have some hope. I found the PointSpriteEnable renderstate remained functional: setting this to false would draw black pixels at the position of my point sprites. I've been trying to get point sprites to work on my XBox. The shader example you give works fine on XP but when I run it on the XBox it just shows up as black boxes. Any idea what I need to do differently in the the pixel shader to ...Show All
