• Vanyel Webservice consumes all the available bandwidth.

                   We are on the test phase of a windows-webservice-Oracle application.Clients would connect the webservice through VPN or VSAT. VPN users would directly connect with the webserver,where VSAT user will connect with the VSAT server which will be routed to the webserver. Now the VPN users have an average bandwidth of 512 kbps and VSAT users have an average of bandwidth 360 kbps.There would be an average of 30 users at a time whom would connect either through VSAT or VPN. Now,if we connect through VSAT environment it runs out of bandwidth.The transacted data may reach upto 1 MB for each user. The web server memory is 2GB.We haven't implemented cl ...Show All

• fewiii Using XSD

  Is there a way to use a XML Schema (XSD) in a project other than referencing the file path or URI I am reading this file using a DataSet's ReadXmlSchema method. dsInput = new DataSet (); string strXsdFile = @"C:\Documents and Settings\My Documents\Visual Studio 2005\Projects\MyProject\JobFeed.xsd dsInput.ReadXmlSchema(strXsdFile); ... I used brute force and used a stringbuilder to create a string, but this is not the most elegant method. ... string strXmlSchema = GetJobInputFeedXsd();  // Uses a stringbuilder to manually create the XSD string Stream strmXml = new MemoryStream ( ASCIIEncoding .Default.GetBytes(strXmlSchema)); dsInput.ReadXmlSchema(strmXml); ...

  I'm writing a VB.Net client application that communicates with web services running on Apache Axis 1.3 and Apache Tomcat 5.5.16. I'm using Visual Basic 2005 Express Edition.

• Khenat.Ram TraceSource & Shared Trace Listener bug

  Hi! I have found the following problem in TraceSource. If I use several instances of TraceSource with one shared listener, and threads try to write their first event into TraceSource simultaniously, then several TraceListeners are created. i.e.: I have multithreading application which works in the following way: 1. First thread creates 2 TraceSource's with name "Name1" and "Name2". 2. First thread creates second and third threads, and run them. 3. Second thread writes an event into first TraceSource. 4. Third thread writes an event into second TraceSource at the same moment as second thread. After that both threads create TraceListener. I use my own TraceListener - MyTraceListener derived from Xm ...Show All

• Steve98796 Windows Server2003 Web Edition and .NET 2.0

  This may be a dumb question, but I couldn't find the answer with a forums search. I am currently searching for an OS for serving computer. I ran accross Windows Server 2003 Web Edition, which pretty much is exactly what I need it for. The problem is, according to the 'compare server 2003' page, Windows Server 2003 Web Edition has NO support for .NET2.0. Now, does that mean that the OS package I purchase will not have .NET2.0 already with it, but I have the option of installing it from windows update/distributable package OR that I will never be able to install .NET2.0 on windows server 2003 web edition due to whatever reasons. If the former, I'm perfectly content to have install it after the fact but, if it's the latter, well then I'm b ...Show All

• Marcin Ksi&amp;#261;&amp;#380;ek Executing a method in a given thread context

  I'm porting win32 code (non visual component or "user control") to .NET. In win32 code, I was using Windows messages between threads to signal events form a worker thread to another thread. This was done to make sure an event handler was executed in the context of the thread having created an instance of the component class. The [non visual] component class use a hidden window to receive the messages from the worker thread it created. Now I'm porting this code to .NET using C# as language. I'm using the socket class and use the asynchronous operation, for example, Socket.BeginAccept to make the runtime use a thread to wait for incomming connections and call my callback function when a connection is available.
