You want the buttons to be added to the toolbar. Right?

You need to google first, if you have "It's urgent please" mentioned in your question.

Open the toolbar in the toolbar editor (double-click on the toolbar in the Resource View) and click on the blank button on the right side of the toolbar to create a new button. Type a suitable ID into the toolbar button's Properties view (something like ID_VIEW_ZOOMIN?). Now draw something on that to represent 'zoom-in' (a magnifying glass with a + usually works). Now repeat (but changing the details as appropriate) for the zoom-out button.

Now you can handle the zoom-in and zoom-out events, probably in your View class.

How to read command line args in vc++.
Is there any predefined function/class available?

What type of application are you working on?
If it's a simple console based application you can read the information in the main function (usually named as argc and argv).

Also you can see here:Reading Command line arguments[^]

You need to google first, if you have "It's urgent please" mentioned in your question.

...and if you're using MFC, see m_lpCmdLine, which is a member of CWinApp.

Command line arguments are available in the main function of your program (that is WinMain for a GUI application). If you're using MFC, your-CWinApp-derived class provides the m_lpCmdLine [^] member.

the code below create a folder in drive E:\ called autorun.inf and other line to create inside autorun.inf folder a text file called protection.txt

now what i want is instead of creating these things in drive E:\ i want the user to enter the drive letter that he wants then these files will be created in the entered drive

#include <direct.h>
#include <fstream>
#include <iostream>

using namespace std;
int main()
{
	_mkdir("e:/autorun.inf");
	ofstream output("e:\\autorun.inf\\protection.txt",ios::out);
	output.close();
	return 0;
}

Thanks in advance

whats the problem in achieving it?
accept the drive letter from user,
form a string that has to be passed to _mkdir, and pass it.
first try it, and then post here if you have any problem. we will definitely help you.

Hi .
Is this what you want?

#include <direct.h>
#include <fstream>
#include <iostream>

using namespace std;

int main()
{	
    char root;
    char path[64];
    cin >> root;
    sprintf_s(path, "%c:/autorun.inf", root);
    _mkdir(path);	
    sprintf_s(path, "%s/protection.txt", path);
    ofstream output(path,ios::out);	
    output.close();	
    return 0;
}

thank you very much this exactly what i want

but if u do not mind i want to ask u some questions about the code that u wrote

#include <direct.h>
#include <fstream>
#include <iostream>

using namespace std;

int main()
{	
    char root;
    char path[64]; //why did u declare path as char and set it to 64
    cin >> root;
    sprintf_s(path, "%c:/autorun.inf", root); //what does this thing mean (%c)
    _mkdir(path);	
    sprintf_s(path, "%s/protection.txt", path); //why did u put two (path) and why did u put here %s instead of %c
    ofstream output(path,ios::out);	
    output.close();	
    return 0;
}

again thank u very much

I'm a chinese, my English may be hard to read, I'm sorry for that. But i will try to explain it.

jon ray wrote:
char path[64]; //why did u declare path as char and set it to 64

64 isn't a regular number, I got it by counting the length of your longest full path "e:\\autorun.inf\\protection.txt", and just pick a number more than it.

jon ray wrote:
sprintf_s(path, "%c:/autorun.inf", root); //what does this thing mean (%c)

%c is mean that it's a character but not others(string), and it's value is determined by 'root'

jon ray wrote:
sprintf_s(path, "%s/protection.txt", path); //why did u put two (path) and why did u put here %s instead of %c

%s is mean that it's a string, and it's value is determined by 'path'.
the second 'path' is use to replace the '%s', and then put the result "%s/protection.txt" to the first 'path', now 'path' has become the full path what you want.

Since you are using C++, try:

string path = root + ":/autorun.inf";
_mkdir(path);
path = path + "/protection.txt";
ofstream output(path, ios::out);

create the button dynamically.
like
CButton b;
b.Create(...);
try to browse for CButton::Create(...)function.
