There is one dirty dirty trick... Open C:\{windir}\system32\inetsrv\MetaBase.bin and look for e.g. "X - P o w e r e d - B y : A S P . N E T" string in it. Actually there are all the mappings as well, but file format is unfriendly. (okay, that's because I view it in notepad  )
Idea look for it in MetaBase is from this article: http://www.codeproject.com/aspnet/teniistips.asp[^].

Hi, how can I load and unload a .dll file at runtime in my C# project. I need urgent reply plz help me. thankx
|
|
|
|

How do you need to load it? Do you need to read it or use it, if you need to use the .dll then there would be no point in unloading it.

thanks for u r help, actually i am doing the same thing as mentioned in www.c-sharpcorner.com/2/pr12.asp, through this way i have to explicitly add the .dll file (component)to my project(using add reference),but i want to add(load) that component at runtime. as we do in VC++.

pakfari:
Use Assembly to load the dll, like so:
Assembly SampleAssembly;
string fullp = ((Full Path to the dll))
SampleAssembly = Assembly.LoadFrom(fullp);
//In order to create an Instance of it you have to grab the type of this class
//use Namespace.ClassName
Type ObjType = SampleAssembly.GetType(Namespace.ClassName);
//Create an instance of your dll here
Activator.CreateInstance(ObjType);
As far as running the Dll, there are a few ways to do it.
but this is how you would/could load it at runtime.
Hope his helps

I will just say Great!!!
It is working ok, can u tell me one more thing. How we can invoke the member functions of the Component using objType.
|
|
|
|

Well, this is where it can get tricky..at least for me. Because there are a few ways to do this, depending on if you want to call the function right then, or place that object in a Collections class and call it later. Hopefully someone will be able to explain it better than I can, but here goes.
This is how I executed a .dll after loading it.
Remember that when you created the Instance it passed back an object
object instance; //what Assembly.CreateInstance returns
object[] args; //Parameters to pass the function
MethodInfo method = type.GetMethod(functionname);
object returnval = method.Invoke(instance, args);
I hope this helps.

Hi,
Anybody knows how to write factory interface handler that will call multiple handlers. I'm using Sharepoint Services in my application. In this sharepoint i can able to add only one event handler. But i'm in situation that my sharepoint has to communicate with multiple event handlers. I asked this question in Sharepoint forums. They suggested that "You can write a factory interface handler that calls multiple handlers. " . But i didn't get any suggestion about factory interface handler from them.
If anybody knows how to write factory interface handler that will call multiple handlers.
Thanks in advance,
Vinoth

They are basically telling you the design pattern for a method that becomes your one event handler, and then farms off the event to other event handlers, based on the code in the class.

Thanks for ur information,
Could you please tell me clearly "design pattern for a method that becomes your one event handler nd then farms off the event to other event handlers, based on the code in the class".
I don't know anything about design pattern.
bye,
Vinoth

Google for 'design patterns'. A design pattern is basically an established design for object oriented software, it's an established way of implimenting something cleanly.
You don't need to know any more than what I said, they are telling you to write an event handler that then sends off events to all the places you want them to go.

hai guys 
i'm a newbie to C#. My doubt is is 'InitializeComponent()' is somewhat similar to a constructor.

Could anyone share it with me plz.

How do you mean ?
This method is inserted by the IDE, and called to set all the properties that you set up in the forms designer. As such, you should never mess with the code here, your changes will disappear. as such, it's also a form of construction activity, I guess. But you should add any code of your own in the spot just below the call that is commented as being the right spot to do so.

No ! 'InitializeComponent()' is a common function that run in the form constructor. But in VS.NET IDE this a protected area of code !! If you try to change any line of code in this function IDE will reproduce the original codes at project rebuilds. In fact this is a scope that IDE put the design time initialization of controls and components there.

What is an easy way to make a program that opens a port on a server and waits for a client to ask for information. How do I do that client part as well? Can your method send both text and numbers?

I figured it out, you use the TcpListener, and the TcpClient.

I want to open a new form in a Windows Application in C# in its own thread. The form has a constructor that takes some parameters (always). The form updates a Flexgrid upon events fired from a live datafeed. The updates can happen quite often and I may have multiple forms open at once with multiple updates happening at once. I have tried to start a new thread, but does not appear to keep the whole form in a new thread.
Any suggestions would be appreciated.
Thanks

How are you opening the form in the thread? What exactly do you mean by

How can you capture the logon and log off event in windows xp.
I am creating a windows service that needs to do something when a user logs on to their account in xp and logs off from their account. It would be good if I can capture their Username as well so I know who is logging on and off.

Thanks
This is good to find out which user is currently logged on. But how can I fire off and event when they log on and off.

I'm trying to take a numeric value from a textBox and compare it against another numeric value that is supplied by the app, but i'm stuk trying to convert the string value of the textBox1.Text to int value for the if statement, i keep recieveing the following errors:
Cannot implicitly convert type 'string' to 'bool'
Cannot implicitly convert type 'int' to 'string'
here is the code:
private void button1_Click(object sender, System.EventArgs e)
{
string myID;
TextBox txtbx = new TextBox();
txtbx.Text = myID;
if (myID = 123)
MessageBox.Show("You are right");
}
I've tried changing the string myID to int myID but it hasn't proven any better, as i get the same errors listed above with int to bool, and int to string as the only difference.
also i'm getting a slightly less important error of:
Use of unassigned local variable 'myID' which i understand means i haven't initiated the variable, but its failing inside the if statement.
I'm still learning so if you guys could help it would be great.
thanks

You are assigning myID with the value of 123 in this if statement. Are you sure this is what you want?
If you want to compare with 123, then it should be
if(myID == "123")

well the truth of the matter is that in the end the desired result will be to pull the data from either a db or assign a solid value at a later date, right now i was just trying to get the unit to run.
thanks for the quotes..... that worked.
any ideas on the "Use of unassigned local variable 'myID'" ?
