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];
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;
}
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.

If you use CFormView as the view class of the SDI application, you can add any controls to its dialog template just like a dialog based application.

In my current project I will be receiving fixed type packets. I need to validate the checksum on those fixed packets..once the validation is successful. I need to strip off the header and buffer the remaining content. And I need to keep doing this in sequential order as the packets I receive. PAckets coming are infinite. So I am having difficutly in how do I handle this entire scenario in C++ programming. I am new bee in Object Oriented Programming... Any help would be great.
THANKS!

You could create a vector<byte> and keep appending the contents into this vector using vector<byte>::insert at the location vector<byte>::end.

How are the packets going to be processed? You say "PAckets coming are infinite" which implies you must use and discard data, otherwise your machine's memory would fill up.
If you want to process packets in the order that they arrive, I'd probably use a deque rather than the vector that superman mentioned, because a deque has good "delete from front" characteristics when compared with a vector.

Thanks Stuart Dootson & Superman !
I will be receiving certain amount of packets but I am not sure exactly how much. There will no memory problem as certainly its being taken under consideration that the received packets will be at certain limit it will not exceed.
whats the difference between using vector versus dequeue or queue technique.
I am explaining my scenario . I have reader thread that will do blocking read and once it receives the first packet which will be of 20W with 1W header with it.. I need to calculate checksum of the 20W packet received. Than I need to read certain fields and need to decide where it needs to be buffered. Before buffering these packets I need to strip off the 1W header. Once the buffering is complete say I might receieve 500 packets of size 20Word. After I stop receving the packets. I need to analyze the packets that being buffered. And these packets are of 2 types theere might be 2W packet and 260W packet or partial packet and each of these packet will have header so. first I need to read the packet header of the first received packet inthe buffer and base don that I need to dispatch those packets to its destined location or hand over to the designated handler.
So confusion is whats the best efficient technique I should use. Using simple array is not best option so thought of asking here. Also how do Istrip off the header from the packet.
Any help woul dbe appreciated. I have just started coding but have not really much coded in C++ .. I am learning by dng google or reading previos discussion here on forum
THANKS!!!!
