Dear Friands,
I have two overloaded methods with the following signatures in 'MyClass' that is a class library in a dll file and I want to invoke a method from this dll at runtime by reflection:
public class MyClass()
{
public int MyMethod(ref int intParam)
{
intParam += 100;
return Math.Sin(intParam);
}
public int MyMethod(int intParam)
{
intParam += 100;
return Math.Sin(intParam);
}
}
When I use typeof(MyClass).GetMethod("MyMethod"); ,System.Reflection.AmbiguousMatchException is throw !!
If I use
typeof(MyClass).GetMethod("MyMethod",new Type [] {typeof(int)});
The second overloaded method with the value parameter invokes.
How can I force the CLR to run the first method and pass the parameter to it by reference ?
Regards,
Xironix

Hi all, I am creating a text mining engine and after a button click i create inverted index and it takes quite a while to do so. Now i want some user interface to tell that something is in progress. i am using a static label lblStatus. and updating its value during different places in the function. but it doesnt work..
lblStatus.Text = "10% Completed";
and so on. but it is not working the label doesnot change it remain the same as it was in the start and when the index is completely created it shows 100% completed....
tell me how it will work.. or advise me wat other method should i use.
Regards,

Use
Application.DoEvents();
|
|
|
|
|
Sir plzz explain a little coz i m relative new commer in C#
Regards,

If you call DoEvents in your code, your application can handle the other events.
Say, you are are updating the label text by 10% within a function. You wont be able to see updated label text messages until the function has completed its execution. If you use Application.DoEvents() just after the update ui code, the function will continue its execution and you UI will be updated
label1.Text="20% completed";
Application.Doevents();
Have a look into this link
http://msdn2.microsoft.com/en-US/library/system.windows.forms.application.doevents.aspx

 Good grief why did you post that entire mess? couldn't you have narrowed it down the problematic portion of the code?
What is with all the string concatenation garbage? Is this production code or some class assignment? Aren't there classes that help generate Javascript code? At lease use a StringBuilder. 
Please someone tell me that this is not reflective of the normal state of web development today!

you can search this error on microsoft.com. It's a common error when you work with ASP.NET 2.0 especially in Windows XP. You can change the enviroment programming to Windows Server 2003 (SP1) which operates better than Windows XP.

with vs.net studio, it is simple to create a window service, and adding a notifyicon to bring it to system tray. But now how to add the context menu to this system trayed window service.

Hi all,
We are similar with Sniffer.NET program (written in VB.NET) in NETWORK topic, it's Packet Filtering.
I want to develop this project, for example "DoS recognition" module.
My idea depends on information in packet filtering to do this module.
For example, we can count the number of packet go through, total length of packets...per second. From these parameters and base on the rules (user defined), we can recognize the DoS such as Smurf or Fraggle attack...
Because of the various of DoS attacks, so I need your support.
Give your idea if you can!;)
I think it's very interesting!
Thanks a lot!

Is there a way to actually stop unauthorized use of code in a DLL?
The article on SecUtil[^] sounds nice, but doesn't work at all, unless I'm missing something painfully obvious.
I've got a signed DLL with a single public class exposing a single public method:
public class Thingy
{
private const string PUBLIC_KEY = "0x00..."
[StrongNameIdentityPermission(SecurityAction.Demand, PublicKey = PUBLIC_KEY)]
public Thingy ()
{
}
[StrongNameIdentityPermission(SecurityAction.Demand, PublicKey = PUBLIC_KEY)]
public int Add (int v1, int v2)
{
return (v1 + v2);
}
}
And I'm calling it in a separate unsigned application:
private void button1_Click (object sender, EventArgs e)
{
Thingy thingy = new Thingy();
int result = thingy.Add(6, 7);
MessageBox.Show("6 + 7 = " + result.ToString());
}
It should be protected, and yet I get my message box "6 + 7 = 13" just fine.
Any ideas?

Okay, it seems to work in .NET 1.1, but not in .NET 2.0.
Apparently .NET 2.0 has said, "The hell with security." One can easily run any code in a trusted zone without any regard whatsoever to standing individual assembly security requirements set by StrongNameIdentityPermission.

Hi everybody!
I want to check if two HTMLDocuments represent the same structure of HTML file. My problem is that I don't know how should I use the WebBrowser.DocumentCompleted Event to be sure that document has been loaded. I've got two files so I should wait for both of them ( how ?)
I would greatly appreciate your help.

You shouldn't. Why are you using the WebBrowser control to compare two HTML documents rather than using System.Net.WebRequest and WebResponse?

I don't want compare each sign, becouse I don't care about atributes. For example:
------- textA ---------
something
cos tam
---- endtextA ----
------- textB ---------
something
style="color: Red;">cos tam
---- endtextB ----
These files are equal.
So I want to create document tree for both files, and compare these trees.

These files are equal, not those
------- text 1 ---------
something.
cos tam
---- end text 1 ----
------- text 2 ---------
something.
style="color: Red;">cos tam
---- end text 2 2 ----

:/ I've forgotten tick "Ignore HTML tags"
These files are equal, not those
------- text 1 ---------
<P align="justify">
something
</p><SPAN style="color: Red;">buhuhu
</sPAn>
---- end of text 1 ----
------- text 2 ---------
<p>
something
</p>
<span> style="color: Red;">buhuhu</span>
---- end of text 2 ----

If you will build a DOM tree you will get different tree's.
You will have to use some other aproach...
