well as they say VB.NET doesnt have pointers...
I remember when I used C++ the only time I used pointer was when I was making link lists. I know that it also has a very good use for virus programming... but really what's the advantage of having pointers (C#)? what kind of a program can you write with C# by using pointer that you couldnt write in VB.NET?
I don't think it is a matter of what you can and can't do with them, I believe it is more about speed and flexibility than anything else.
hmm what is the advantege and disvantage of pointers?!?
One of advantages of using pointers is for returning more than one value from a function call. Since a pointer is changing the value at the memory address, you could pass 4 variables to a function and have all of them changed all at once.
that's a refrence I believe:D I mean pointer as C++ pointersQuote:

In VB you just pass ByRef instead of ByVal to get the same effect. Is that what your talking about?Quote:

me? no:)Quote:

POINTERS!!!! the thing that doesnt exist in vb.net. :D
I mean what is the point of being able to change a memory address manually?! VIRUSES love to do that, dont they?:rolleyes:
The only thing I know is you can speed up your apps with them. When you reference a memory address with a pointer, the compiler goes straight there to get the value. When you reference a variable, the compiler has to check where that value is held in memory then go get it. Very little overhead though. The speed comes in real handy in loops and intensive processes.
At least that is what I have been told from others.
hmmmmmm
