A would guess that Excel is reading the file as an ANSI file, that is/was the standard text format in windows prior to unicode.
Try the Encoding.Default encoding, that will give you the encoding currently used by the system for ANSI files.

I need to ping IP with linux commands "ping xxx.xxx.xxx.xxx" . and run it with Mono on Linux server.
Let's see my code...
Process P = new Process();
P.StartInfo.CreateNoWindow = true;
P.StartInfo.FileName = "ping";
P.StartInfo.RedirectStandardOutput = true;
P.StartInfo.Arguments = " 202.57.191.167";
P.Start();
P.WaitForExit();
string output = P.StandardOutput.ReadLine();
while (output != null && output!="")
{
Console.WriteLine(output);
output = P.StandardOutput.ReadLine();
Thread.Sleep(500);
}
Console.ReadLine();
Then upload and run it,it throw exception...
<br />
"Unhandled Exception: System.InvalidOperationException: UseShellExecute must be false when redirecting I/O.<br />
at System.Diagnostics.Process.Start_shell (System.Diagnostics.ProcessStartInfo startInfo, System.Diagnostics.Process process) [0x00000]<br />
at System.Diagnostics.Process.Start_common (System.Diagnostics.ProcessStartInfo startInfo, System.Diagnostics.Process process) [0x00000]<br />
at System.Diagnostics.Process.Start () [0x00000]<br />
at (wrapper remoting-invoke-with-check) System.Diagnostics.Process:Start ()<br />
at ProcessLinuxCommands.Program.Main (System.String[] args) [0x00000]"<br />
Could u help me what is this bug?
Does Mono implement the Process class?
thank =)

How about trying to set the StartInfo.UseShellExecute property to false as the exception message indicates.?

Hi
I am working on a desktop application using C# and .NET 2.0.
In my DataSet I have two tables say table1 and table2. They have one to many relation (no rule is set like for update, delete or accepct/reject changes). When I drop a binding source for the parent table i.e table1 on the windows forms, I get another binding source for child i.e table2BindingSource1 after rebuilding the project. That is really helpful because when I set
//this.BindingNavigator1.BindingSource = table1BindingSource;
The self created BindingSource collaborates with the navigator itself and I need not to do any extra coding.
Now the problem is when I do
//this.BindingNavigator1.BindingSource.CancelEdit();
to cancel any changes made to DataSet in case user clicks Delete button one the Navigator.
This only works for the parent table i.e table1 and not for the child table or say for self created BindingSource.
How can I apply this CancelEdit for both the tables in the DataSet ( for both BindingSources ).
Can anybody help me out?

Hi, I have made a web service and when I build the application and add the Web Reference in my Windows Application, I am not getting the Begin and End Method for making Asynchronous Web service calls.
Its urgent. Kindly help. I am using C#.

Did you manually create the web reference or did you use VS to generate the web reference?
If you are using VS remove the reference to the web service and delete the generated cs file. Then add the reference again, there should be no probably with this since all the async behavior is controlled by .Net on the client application side. The remote server does not need to know anything about the async behavior of the client.
If however you have created the class yourself you will need to manually add the async calls.
Here are some useful links:

Hi,
I have done exactly according to the link provided by you. I created a webservice and added the reference in my windows application.
I then created an object of the web service class and tried to call the Begin method, but the begin method does show up. I am not able to call the Begin method of my web method.

Neeraj

Sorry my information is a little out of date. Things have changed it seems from 1.1 to 2. Anyway I created a quick test service and console app. You need to assign an event handler to the completed event for the method invoked. Then invoke the method using the async method call. The result of the method call is contained in the event args passed into the event handler.
You have to think about the race condition between the main thread and the async thread when using this method of invoking the async call.
Here is my code:
static void Main(string[] args)
{
TestConsoleApp.localhost.Test Test = new TestConsoleApp.localhost.Test();
Test.HelloWorldCompleted += new TestConsoleApp.localhost.HelloWorldCompletedEventHandler(Test_HelloWorldCompleted);
Test.HelloWorldAsync();
Console.ReadLine();
}
static void Test_HelloWorldCompleted(object sender, TestConsoleApp.localhost.HelloWorldCompletedEventArgs e)
{
Console.Write(e.Result.ToString());
}
Hope this makes sense

So it means there is no concept of Begin and End Methods in 2.0

By the looks of it no, you will need to create a way of checking that all the async request have completed.
For more info on async see:
http://www.developer.com/net/net/article.php/11087_3481691_1
and for creating async ASP.NET pages that consume web services see:

Hi, All is well, but when I try to implement your Test_HelloWorldCompleted method, the HelloWorldCompletedEventArgs does not come up. I can only see the HelloWorldCompletedEventHandler.

Please don't repost problems so quickly. It's unfair on others who have also posted questions. People answer questions here of their own free will, so you have to wait until they can get round to it. If it's really, really urgent, then you will have to post it on a site where people get paid to solve problems.

I am so sorry, but I thought my previous question did not explain my problem well. I will keep this in mind for the next time.

Hi,
i have written a code for converting Xls to Xml but got struct upwith a situation.Say, a parrent node has 4 child node and those child nodes has sub child nodes.
In this 4 child nodes, any 2 child nodes may be same(including their sub childs). If that is the case the second occurance(duplicate) should be removed.
But any 2 child node value is same but the sub child are different means i need the append the subchild of 2nd occurance with 1st occurance and remove 2nd occurance
What shall i do??
Thanks,
Srikanth

Sounds like when you find two nodes that are the same at one level, you need to write a recursive function that steps down to see if the child nodes are also the same.

Download the firebug add in for firefox, then the code will break at your error and you'll be able to diagnose it. Without you posting the code, there's no way anyone can help you, and the FF/FB solution is your first port of call.

Perhaps if you show some of your code.

I want to know whether the session id is unique when a group of people browsing through the same site, same page at the same time.
Can anybody help?
Please send me the code which will generate the session id.

SessionID is generated in RAM on the Webserver and It is not a persistent property. It is unique at the time is it created.but not guaranteed to be unique. 
Same SessionID might be used again after your Web server has been restarted. This means that you shouldn't attempt to track the same user over time by using her SessionID.

I don't think so. I think it's stored as a cookie in client machine.

But that is generated by the server !!!
