You need to use either KeyDown or KeyUp events.

if (e.KeyData == Keys.N && e.Modifiers == Keys.Control)
{
    // Do your thing
}

Hello,
I have a web site with files and direcotires (with files and other directories and files.....in each).
I need to find a particular file in this site (i will provide the main site and it will search recursively inside it and inside the folder to find the file i need). How can i do it?

First of all this should be in ASP.Net forum.
Use the DirectoryInfo and FileInfo classes to perform the search.

Well, that can do the search everywhere provided you have the read access in that website.

Hi my friends;

I have a different problem. I have a main form that is MDI parent of other forms. I use speech recognition, and I started it as a thread in my main form. It works fine while opening child forms or closing them. But problem begins here. For example I have an active MDI child that have a method or button click event. How can I call the method of my active form from it's MDI parent. I want to do this because I use speech recognition, I want to guide program with my voice commands. Like following I want call DoJob method.

Form frm = this.ActiveMdiChild;

frm.DoJob();

Thank you.

Not sure which exactly is your problem, but you can do it this way:

1) In the child form, the DoJob() method must be either public or internal (in order to enable access from the parent form).

2) In your parent form you can do something like:

ChildForm cf = (ChildForm)this.ActiveMdiChild;
cf.DoJob();

where ChildForm is your child form's class name.

2+2=5 for very large amounts of 2
(always loved that one hehe!)

You mean you need to call the method accros threads? If so:

frm.Invoke(new MethodInvoker(delegate() { frm.DoJob(); }));

Hello Friends.
Suppose I have two functions name
GetBUUser(); && GetISUser(); And both these function call a function name
LoadUserBUStatus(); Now in LoadUserBUStatus() function how do I know which is the caller function..? I hope I made myself clear..
Thanks in Advance..

You need to use Reflection and the Stack. Check out this[^] article.

Ok, I'll bite, why not use a wherefrom parameter, reflection and the stack seems both convoluted and expensive. I can understand if he has no control of the design of the calling methods but he implies he is writing them.

When I read the question I immediately remembered needing to do something like this before and how I solved it. It was painful which is why it's imprinted on my memory and popped straigt to the tips of my fingers.

In my situation, I couldn't alter the parameters received without breaking other stuff (I can't remember why an overload wasn't allowed, but there was a reason), so sending an additional parameter in the calling method wasn't an option for me.

I agree, a 'whereFrom' parameter would definately be easier for the OP.

When playing with the stack at runtime, remember that the JIT is allowed to perform inlining, so stack frames might disappear in release build (possibly even depending on the installed .NET version - the inlining heuristics are tuned from time to time).
You'd have to mark all three GetBUUser(), GetISUser() and LoadUserBUStatus with MethodImplOptions.NoInlining to be safe from that.
But on 64-bit .NET, even that isn't enough: there the JIT will perform the tail call optimization, which can also cause stack frames to disappear. Unfortunately, there's no way to disable tail calls.

You should avoid analyzing the stack at runtime at all costs.
