.NET Development new TCPChannel() throws SocketException after several calls
Hi, in my remoting server app, I have the following code: BinaryServerFormatterSinkProvider provider = new BinaryServerFormatterSinkProvider(); provider.TypeFilterLevel = TypeFilterLevel.Full; IDictionary props = new Hashtable(); try { props["port"] = remotingPort; TcpChannel channel = new TcpChannel(props, null, provider); ChannelServices.RegisterChannel(channel, false); channelName = channel.ChannelName; after this server having been closed and re-opened several times, and the client still running, I sometimes get a SocketException on the "new TcpChannel(props, null, provider)": An invalid argument was supplied StackTrace: at System.Net.Sockets.Socket.DoBind(EndPoint endPointSnapshot, SocketAddress socketAddress) at ...Show All
Visual C++ CString pointer compatibility with const char* in VS 2005
Hi, I used a CString variable to instantiate a "const char* " argument of a C++ function. The VS 2005 IDE sent out an error C2664: 'xxx' : cannot convert parameter 1 from 'CString' to 'const char *' message. Does anybody know how to deal with the problem Thanks, Jason LPCTSTR et al are probably best treated as typedefs for Win32 APIs, and not used in your own code. This "hungarian notion" for typedefs doesn't buy one very much other than to introduce "two different ways to say the same thing" in your code. For the original poster, I was suggesting a general replacement of char with TCHAR (using * and const as usual), so that assignments from CString internal buffer ...Show All

Visual C# Question regarding InitializeComponent() in ASP.NET application.
Is InitializeComponent() moved to .designer.cs file if this is designer generated code, how come it is not there neither Do I have to manually create it (I am using Visual Studio 2005) In .Net 1.1, Visual Studio would look at your ASPX file and generated C# code for you. In .Net 2.0, with partial classes, there is no further reason for it to exist as C# source code. The ASP.Net runtime looks at the ASPX file and generates the IL code directly when the page is accessed. You do not have to write it manually (progress makes things easier...) ...Show All
Visual Studio 2008 (Pre-release) How to display different UIs according data-loading status in WPF?
I use a webservice to provide data to wpf client application. when the data is loaded completely, I use a LixtBox to display it. But since it will take a while to load the data, I hope to show a progressbar during loading process. And if errors occur during loading, a label should be displayed instead of the ListBox.

Game Technologies: DirectX, XNA, XACT, etc. End users shouldn't have to rewrite XNA math functions in order to improve performance.
The overhead of passing a 64 byte Matrix by value is significant. Most especially when you are comparing two matrices for equivalency (==), or performing a Vector*Matrix multiplication (Vector3.Transform(Matrix)). The following matrix comparison function performs 5-10 times better than your built in == comparison. If the matrices are equal, then it is about 5 times faster. If they are unequal then it fails fast, and is about 10 times faster. public static bool Equals(ref Matrix a, ref Matrix b) { // i check the diagonal first for quick fails return a.M11 == b.M11 && a.M22 == b.M22 && a.M33 == b.M33 && a.M44 == b.M44 && a.M12 == b.M12 && a.M13 == b.M13 && a.M1 ...Show All

SQL Server Using Array Variable in ForEach Loop Container
Dear all, I have a problem using SSIS since I was a beginner, the problem is I have to do some data transform from flat files into database.
