• Game Technologies: DirectX, XNA, XACT, etc. So how does this (non)commercial business work?

  Can anyone please enlighten me on how this all will work. How I see it, there are two points for having XNA. 1. To let gamers make Xbox 360 non-commercial games freely to play on their own consoles. 2. To let gamers make Xbox 360 commercial games that they may transfer over live. But can we sell these games & start a business And where do our limits end & then begin again with Pro I have been trying to start a video game business for years now, working with teams and software, and Microsoft XNA can be a new pedestal for my team and business.   Thanks in advance.

• Visual Studio 2008 (Pre-release) IIS and .svc file

  Hi, I hosted all services in IIS, for every service must be a .svc file to mapping. The question is whether can combine all .svc file to a single file or can not use .svc file Thanks, Zhihao You can host all of your services as a single assembly containing endpoints for each service. The best way to accomplish this is to create a WCF service library project (If you don't have the wcf extensions for visual studio you can download them)... After you build the project you can host the assembly in IIS and hit each service based on the address of its endpoint.. let me know if you need more info - I can post a sample if you like.. ...Show All

• .NET Development TcpClient & TcpServer

  Dim client As New System.Net.Sockets.TcpClient Dim Buffer() As Byte = System.Text.Encoding.Default.GetBytes("KKKK") client.Connect(DestIP.Text, DestPort.Value) client.GetStream.Write(Buffer, 0, Buffer.Length) client.Close() I used this code to send data through a port and an IP address. I have succeeded in sending data through a LAN. I don't have a static IP. Can I send data to other computers on the net without a static IP Regards Glenn Zarb If you setup a central server in-between 2 clients, both clients could just call the server. The server would keep track of anything that needed to be sent to the client and when the client checks in, it gets delivered. ...Show All

  Hi I do not want the cell to highlight when clicked on, i want the cursor to go in immediatly. So i set "editmode" to EditOnEnter. So as soon as you enter the cell it places the cursor there and you see no highlighting. But now if i add values to cells through code it is then highlighted. I need it to be always with just the cursor in the cell. Any other way Is there a way to simulate a click on that cell or select that cell or make that cell with focus Another problem is when i add my value to the column then try to add a row using the following dtgrdGetHandle.Rows.Insert(1, 1); i get an error "No row can be inserted after the uncommitted new row."

• Software Development for Windows Vista Vista Compatibility Check

  Where can I find a utility to see if my VB6 apps will run on Vista I've been to this site, http://msdn.microsoft.com/library/default.asp url=/library/en-us/dnlong/html/AppComp.asp and I downloaded one tool, but that was to see if apps ran on XP.

• .NET Development fast ping

     Hi,    I need to write a fast ping program to ping class C & D IP addresses. I have written a piece of code to open a socket, connect to it and receive data from it with a timeout. This is fast enough for a few IP addresses but  I would need to ping 255x255 IP's. I have put this code on a separate thread which calls an asynchronous method to loop over the IPs. This is taking a minute for each set of class D IP's. How do I make it run faster Thanks  PS: I am using the 1.1 framework I'm not sure if it works or not but Also try to resuse IcmpPacket packet = new IcmpPacket (); use same packet for each function call in loop be ...Show All
