If you receive a SocketException when calling Socket.Shutdown(), use SocketException.ErrorCode to obtain the specific error code. Once you have this code, refer to WinSock 2 error code documentation[^]for a detailed description of the error.

I believe that the easiest way is to just throw an exception and catch it.

string trace = null;<br />
try { throw new Exception(); } catch (Exception ex) { trace = ex.StackTrace; }

Totally off subject, I got a copy of xacc.ide the other day, and it exceptions on load. No meaningful information, just ungracefully croaks.

I have been trying to access frames with webBrowser document.

I always get the system telling me I don't have access. I read up on the net and it is a known issue due to security.

Has anyone ever achieved this?

HTMLDocument doc = (HTMLDocument) i_webBrowser.Document;
object aRef = frameNumber;
object anObj = doc.frames.item(ref aRef);
HTMLWindow2 aWindow = (HTMLWindow2) anObj;

HTMLDocument aDoc;
// the line below will cause the security exception
aDoc = (HTMLDocument) aWindow.document;

Proper steps are:
1) Click on one menu item
2) Go to the event tab on the property panel
3) Double click on the click event; an event and handler shall be added
4) Find the handler function and fill in the function body with your logic

Pls can any help me figure out if there is any error in this web sevcice client. I have included Username and Password for testing. When

http://dedicated134.eapps.com/pencomweb2/PENCOM_WebService.asmx is registered
classes exposed are:

PencomServer2.PENCOM_WebService c1 = new PencomServer2.PENCOM_WebService();
PencomServer2.RSANO_Response c2 = new PencomServer2.RSANO_Response();
PencomServer2.EmployeeRecord[] record=new PencomServer2.EmployeeRecord[2];

but of tesing purposes
(string r = c1.TestPenComService();)
can be used.

Sample code is:

required namespace are:

using Microsoft.Web.Services3;
using Microsoft.Web.Services3.Design;// formerly Microsoft.Web.Services3.Policy
using System.Security.Permissions;
using Microsoft.Web.Services3.Security;
using Microsoft.Web.Services3.Security.Tokens;

public void ReadData()
{

//Secure Service
//http://dedicated134.eapps.com/pencomweb2/PENCOM_WebService.asmx
// Create an instance of the Web service proxy

PencomServer2.PENCOM_WebService c1 = new PencomServer2.PENCOM_WebService();
PencomServer2.RSANO_Response c2 = new PencomServer2.RSANO_Response();
PencomServer2.EmployeeRecord[] record=new PencomServer2.EmployeeRecord[2];

// This is the username security token which is used by the service proxy
UsernameToken token = null;

Username = "PENSUREPFA";
Password = "NS946343PE";

byte[] passwordBytes = System.Text.Encoding.UTF8.GetBytes(Password);
string passwordEquivalent = Convert.ToBase64String(passwordBytes);

token = new UsernameToken(Username, passwordEquivalent, PasswordOption.SendHashed);

//PolicyEnforcementSecurityTokenCache.GlobalCache.Add(token); //wse3.0

//Get the SoapContext for the SOAP request that is being made to the Web service.

Microsoft.Web.Services3.SoapContext requestContext = c1.RequestSoapContext;

//Add the UsernameToken to the WS-Security SOAP header.
requestContext.Security.Tokens.Add(token);

//Encrypt the UsernameToken in the WS-Security SOAP header.
//X509SecurityToken serverToken = GetSecurityToken();
//requestContext.Security.Elements.Add(new EncryptedData(serverToken, "#" + token.Id));

//Create a new instance of the MessageSignature class by using
//the UsernameToken just added to the WS-Security SOAP header.
MessageSignature sig = new MessageSignature(token);

//Add the digital signature to the WS-Security SOAP header.
requestContext.Security.Elements.Add(sig);

//Specify the time-to-live (TTL) for the
//SOAP message to diminish the chance of someone
//intercepting the message and replaying it.
requestContext.Security.Timestamp.TtlInSeconds = 120;

//Call the Web service.
//c1.UploadEmployeesRecordToGetRSANos(record, 0023);
try
{

string r = c1.TestPenComService(); //test version
}
catch (Exception g)
{
MessageBox.Show(g.Message);
}

}

On trying to connect to a test method, the respose I get back is:

Microsoft.Web.Services2.Security.SecurityFault: The security token could not be authenticated or authorized ---> System.Exception: WSE563:

I have two DataGridViews side by side with the same number of rows and columns. They connect to untyped DataSets. When I select a specific sell in the left DataGridView, I want the same cell to be selected in the right DataGridView. How do I go about doing that?

Thanks!

It also the same. You can take your java source code and a little bit changes then you can compile it using C#. The language is almost the same.

I know it is very similar but the thing is there are functions in java that i used that are not present in c# also i am not an expert in c# so for example i don't know how to represent the car as a moving object on the screen...
thx

Windows Form in C# appears to be equivalent to Frame in Java.
