Hi masters!
--------------
Say we wanna call SetTimer(); As you know (or had better to know  ), one of Its parameters is pointer to a function to be called after a certain time is elapsed (that's a call-back function).
how can I define a member function to pass to it?
I tried the following methods, but I got an/some error/s in both cases:
1- SetTimer( ..., &CMyclass::MemberFunction);
2- SetTimer( ..., Memberfunction);
unfortunatly I don't remember the exact error/s now  and I'm not home to reffer to my project ...
I'm using VS 2005
Thanks in advanced ...

By making it static.

Thank you masters!

You can't, except if the function is a static function. Because member functions and non-member functions do not have the same prototype (for the member functions, there's an implicit 'this' parameter).

Thank you for your reply But I got another question:
You meant static functions doesn't have this within them?
Thank you masters!

Because they're class methods (instead of instance ones). Since a static method cannot access instance data, it does NOT need the this pointer.

I need some help creating a unix shell using c++. Can anyone help me out here. Starting from scratch.
#include <iostream>
using namespace std:
Are the only includes I have so far. Code wise I have started it but no clue where should I end up.

Wow. Other than the syntax error, you're almost done!

using namespace std;
Is this better.
Anyhow I'm trying to code the unix command cd in C++. Any pointers.

Try SetCurrentDirectory().

hmmm... do I need the #include <winsock2.h> for that command?

SetCurrentDirectory() does not require the iostream file.

thanks man...
Sorry for being annoying...
And I'm just asking... can you do that for all commands.

Use something like setDirectory() for all the unix commands.

Uh, no. You would only use that if you wanted to set the directory of the FileDialog object's window to be the specified directory, and only if you were using Java.

What you mean by creating a shell ? I would suppose that almost (or maybe even all) commands in the shell are just different executables.
|
|
|
|
|
that could be true... but i want to do it manually... and not by executables. I know they can but I choose to do it the other way so that I know how the command is implemented.

Back in DOS days, it had internal (i.e., those contained within command.com) and external commands (i.e., separate executables).

It is a daunting task, you know. Good luck.
