...so with a dll written in VB2010 and included in my C#2010 code it works fine...now only the question is if this will influence the performance in a significant way or not...

Do you have JustDecompile[^]? If not, you really should consider installing it - with it, you could decompile your VB version, and then view the resulting source as C# to see what's happening.

I am getting into final year of my CS and i want to build an application as a FYP that stores the history of all programs that have been executed on windows.
please anyone of you can guide me in this regard

Certainly.
I give you my full permission to start work on it.

If you want someone to do the design and/or development of your project then you are out of luck. This forum exist to help with specific technical problems within the work that you have done. If this project is beyond your skills then switch to something that you are able to do.

Certainly. As you are going to be working with Windows APIs, you should think long and hard about whether C# is your best choice. Also, you need to consider what a program is - for instance, what if I open something from the Control Panel?

You're also going to need to come up with a method to track this information. Windows doesn't track what applications were launched when, so you'll have to do this yourself.
I would suggest an API redirection on the various versions of the Win32 CreateProcess function. Look into a library called Detours, found here[^]. The Express edition is free but only works on 32-bit processors. The Pro version works on both 32 and 64-bit processors, but'll cost you $10,000 (US).
Warning! This is an extremely advanced topic dealing with Windows internals. If you don't know how Windows works, change your project right now.
Have fun!

Hi Everyone,
I am trying to make a program in Visual Studio using C# that would look and function like OSX's Automator, or the Java program Action(s) (http://app.jbbres.com/actions/). I am running into a bit of trouble, however, when trying to design the piece of the program where when I drop the selected action onto the box on the right half of the screen, it shows additional parameters to enter to tailor the action to the users' specific needs. I am thinking about using custom controls for my additional parameters, but I am unsure of which type of control would allow me to add custom controls within itself in such a way that they can be rearranged, and you can scroll through them if the controls extend beyond the edges of the window. Does anyone have any suggestions on what I should do?
Thanks,
Bobby

I made a class for Complex Numbers. I don't know what to write in the body of my override function.
public ComplexNumber(int real, int imagine)
{
Real = real;
Imagine = imagine;
}
public static ComplexNumber operator =(ComplexNumber a, ComplexNumber b)
{
return new ;
}

You cannot overload the = operation, since that's an assignment.
You CAN overload the == operation, which checks for equality and returns a True/False value (which you didn't specify the return type as boolean, BTW.)
Also, if you overload ==, you MCUH also overload !=.
|
|
|
|
|
I don't get it, still. Would you please give me an example by coding? Or can you complete my function as what you think it is right?
|
|
|
|
|
THe problem is I don't know what you're trying to do.
You CAN NOT overload the = operator since that's an assignment.
You CAN overload the == operator because it's a comparison operation.
BUT! Your code says you want to overload the assignment, which you CAN NOT do, and frankly there's no reason to!
So which is it???
|
|
|
|
|
Now I've got it. I thought there is a possibility to do so and now I can see there isn't. Thanks Dave 
|
|
|
|
|
Are you trying to assign a to b here?
|
|
|
|
|
Yes, I want to do that but I've got that there is not such a possibility for the "=" operator, according to what Dave was trying to tell me.

I can't see much sense in trying to assign a ComplexNumber from two others like this. Do you really mean it to be the summation of the two complex numbers to form the new one? If so, you would override the + instead. Have a look here[^] for details.

No as I said before, I somehow misunderstood the whole thing. By the way thanks for your attention and guidance

You should typically implement a function Clone that will create a copy of your class. See MSDN documentation for IClonable.
public ComplexNumber Clone()
{
return new ComplexNumber { Real = this.Real, Imagine = this.Imagine };
}
By the way if you want to implement IClonable, it would be preferable to use explicit interface implementation so that your regular Clone function could returns a ComplexNumber (not sure if it still necessary with recent C# compiler).

I guess you are a C++ programmer (your user name further reinforces that impression). In C#, you cannot override assignment; a = b for a reference type will always assign a to exactly the same reference as b, and it's not possible to change this behaviour. (I think this is good because it means you know what a line is doing, whereas hiding copying in = requires you to know things about the class you're using.)
If you want to create copies of an object, you should implement ICloneable (but read this[^]), a copy method (e.g. public ComplexNumber Copy() { ... }) and/or provide a copy constructor (i.e. a constructor that takes a ComplexNumber).

You're completely right. I should try that instead. And by the way, I know there is a function in C++ called atoi but It has another meaning to me. It actually represents my slogan in a short form which is the same with that function's name! 
Thanks for your help
