Posted By:      Posted Date: September 23, 2010    Points: 0   Category :WCF
 

Hi Everybody 

I am new to this WCF and WCF forum. I want to develop a chat application using wcf , so  i  have downloaded a chat application from "http://www.codeproject.com/KB/WCF/Chat_application_using_WC.aspx ". It works fine in my "LAN" but if i am trying to connect to a wan ip i am getting err ors. I have used "Port forwarding" also in that applicatiion. But still i am getting this error. I have mentioned the error code below. Please provide any solution for this. 

Error code:

System.InvalidOperationException: Could not find endpoint element with name 'ChatEndPoint' and Contract 'ChatClient.ICharService' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this name could be found in the client element. at System.servieModel.Description.ConfigLoader.LoadChannelBehaviours(ServiceEndPoint serviceEndpoints, String ConfigurationName)

at System.ServiceModel.ChannelFactory.ApplyConfiguration(String configurationName)

Error Handling: Throwing Custom Exception Types from a Managed COM+ Server Application

  

Exception handling semantics in .NET are based on type, so you can create custom exceptions that have their own properties and methods. In .NET, exceptions are first-class citizens, and since they're the built-in error handling mechanism, all .NET-compliant languages must support exceptions. In addition, COM+ services are available to .NET code as Enterprise Services, so you can leverage exceptions in your Enterprise Services design.In this article the author describes custom exceptions, throwing exceptions across COM interop boundaries, and working with Enterprise Services.

Hello everyone,

I am working on sharepoint 2007 and I was editing the webpart of the software and after adding the predefined employee search table, the server has crashed while trying to access the server remotely with the following error message:

What will be the course of action in fixing this error.

Also the site is complaining of an invalid certificate even after adding an exception.

Any help would be greatly appreciated.

Application just crashes without error

  
Hello, I'm using Visual Studio 2010 Premium edition on a Vista 32-bit machine. I've created a WPF application that has references to some old DLL's (older version of Framework). The application needs to load some stuff and then display a map. When I run the app in the debugger of VS2010 it always works!! But when I want to start the app as a normal .exe application, it crashes without an error. It writes a line in the Windows Log: It's an Application Error 1000   Application error Norma SEH Module.exe, version 2010.8.1.0, timestamp 0x4c737108, module error clr.dll, versie 4.0.30319.1, timestamp 0x4ba1d9ef, exceptioncode 0xc0000409, errormarge 0x002b5b8c, proces-id 0x121c, Application starttime 0x01cb435c02d99ad2.   In my app.config the frameworks are defined like: <startup useLegacyV2RuntimeActivationPolicy="true"> <requiredRuntime version="v1.0.3705" safemode="true"/> <supportedRuntime version="v4.0"/> <supportedRuntime version="v1.0.3705"/> </startup> The weirdest thing is that they app.exe does work 1 time and then it won't work until I create a rebuild with VS2010. Can someone please help me out here? I've searched the whole internet and can't find anything. Thanx in advance With best regards, Alex van der Lans Team Leader | Software Engineer URL: http://www.

Source and target both are sql server and the error message is generated in the validation phase of the connection manager connecting to target database. SSIS 2005 SP2 64 bit environmentRaju
