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

In VS2003, when you select a menu item and click on the event tab, you should see the following events:
Click
DrawItem

WSD 3.0 UsernameToken (Sign a SOAP Message by Using a UserName and Password )

okoji Cyril4-Jul-06 6:30

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:

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...

If you create a new Windows Form, then use the event Paint.

private void Form1_Paint(object sender, PaintEventArgs e)
{
  ...
}

Then write your code in this method. For example :

private void Form1_Paint(object sender, PaintEventArgs e)
{
  e.Graphics.DrawLine(new Pen(Brushes.Black, 1), 0, 0, 50, 50);
}

That code will draw a black line with width = 1, from (0,0) to (50,50)

What problem do you have in writing a class file? Would you please elaborate this?

Just add one class file in your web application, and define all data access functions in it.

Also you can define a function in the class that will dynamically fill the dropdown list by passing it as a parameter by reference.

Converting a string to a DateTime object (globalization question) [modified]

[edit]I'm using .NET 1.1[/edit]

I have a date in the form of a string, in the American format, MM/DD/YYYY. How can I create a DateTime object from this string, irrespective of the current culture?

In other words, even if the current culture is French, the incoming string 11/03/2005 should be interpreted as Nov 03, 2005. I want to do this without changing the current culture.

I tried doing

DateTime suspDt = Convert.ToDateTime(strDate, new CultureInfo("en-US"));

but that didn't work. Sniff | :^)

Thanks in advance! Smile | :)

Cheers,
Vikram.

Hi,
Try something like:

DateTime myDateTime = new DateTime(year,month,day);
The year,month and day can be substracted from the string if you know their exact position, using Substring and IndexOf. It helped me a lot sometimes. Hope it helps you. Big Grin | :-D
