• Visual C# C# threading issue

  Ok, I'm having a bit of trouble with this one. Can somebody help me out and perhaps give me a better idea Problem: In a nutshell, I want to synchronize several different threads but can't. One thread, we'll call it A, produces other multiple threads, B,C, and D. These threads execute asynchronously with A. B,C, and D will synchronize with each other, but not with A. A creates these threads and moves on to do other work, but requires B,C, and D to continue. It executes a wait on a eventwaithandle that only B,C, and D can signal (this eventwaithandle is encapsulated inside of a class. There is only one object of this class used by all of these threads and the primary thread. So they signal the eventwaithandle in this object, but the signal ...Show All

• .NET Development Remoting Examples in C# which can call Remote Objects From Different Application Domain.

  Hi, Remoting Examples which has Config Files in Both Client as well as server. Remotings sole purpose is for communicating across app domains or processes so any example of remoting will show you what you want. If the client resides in one app domain (same or different processes, it doesn't matter) and the server in another then it is cross domain calling. Refer to the following links for samples of remoting client and server config files. http://msdn.microsoft.com/webservices/remoting/default.aspx http://www.c-sharpcorner.com/Code/2004/Sept/NetRemoting.asp Michael Taylor - 12/29/06 http://p3net.mvps.org ...Show All

• .NET Development Kerberos Delegation issue! Web server isn't utilizing client's credentials to access remote resource

  Hi, I'm developing an Intranet application that requires the Web server to impersonate a client to access remote resources (the app accesses my company's exchange server using WebDAV) on behalf of the client (all within the same Active Directory domain). However, I'm having a problem with the authentication delegation part- I don't think the user's credentials are being passed to the exchange server). In my app, I attempt to use the DefaultCredentials of the user (which should be  the user credentials of the logged-in user, since we use Integrated Windows authentication): Request.Credentials = CredentialCache.DefaultCredentials; If I build my own CredentialCache object (complete with hard-coded username, password, and domain ...Show All

• .NET Development Custom Types with no public default constructor

  Hi, I would like to know if there is any possible way to pass a custom type to a web service that does not have a public default constructor. I have a business object and I do not want to expose the default constructor to the users as the object needs to be properly initialised before use; however I get a reflection error when trying to pass the type to a test web service. I have tried to pass both internal and protected constructors but no luck, are there any attributes or other methods that would be able to achieve this. Any ideas would be much appreciated. The workaround only works if you not using the type as an input parameter, otherwise you will get the exception while reading inp ...Show All

• Visual Studio Express Editions Convert Byte Array to Int, Long, etc.

  Does anyone have a quick way of converting a byte array to an integer, long, etc. I have been trying different encoding types and also a Marshal.Copy but I keep getting unexpected results.
