Does anyone know how to use the command line arguments with Visual C++? I have used it in Linux like this: void main (int argc, char* argv[]) and it worked fine, I wonder if it is possible in windows/Visual C++! Your response is really appreciated.

Visual C++ works the same way: void main(int argc, char* argv[]) argc contains the number arguments argv[] is an array of pointers to character strings argc equals number of arguments plus 1 argv has pointers to argc plus one strings: With no command line arguments (n=0) argc equals 1 argv has pointers to 2 strings: argv[0] contains the name of executable file argv[1] contains null With n command line arguments argc equals n + 1 argv has pointers to n + 2 strings: argv[0] contains the name of executable file argv[1] to argv[n] contains the arguments argv[n+1] contains null

Yes, as egkenny said, its the same in VC++.

Thank you guys for responding. Well, I tried it but it seem like I am missing something: For me, when I run it in Linux environment, I use the g++ compiler and create the object output file ( by using the -o operator) and then I type this output file along with my input files in the command line. In VC++, to run the program I just click the "!" button so I did not know where to list my input files. Any further help please?

Normally you do the same thing in Windows by opening a DOS command window. If you want to test it in Visual C++ do this: Select: Settings in Project menu Select: Debug tab Program Arguments: enter command line arguments here

Thank you egkenny, it did work.. Now I've one further problem, that is how to use a wild card in the command line arguments.. the program i am working on requires entering a punch of different files each time i run it, for example if i have these files in the directory a1.txt a2.txt a3.txt b1.txt b2.txt b3.txt c1.txt c2.txt c3.txt, to enter the files start with a I use the * wildcard so a*.txt will make the program (in the linux environment) recognizes 3 files, similarly I could enter *2.txt or *.txt. When I did this in VC++ it did not work, it read a*.txt as 1 file and could not open it " because it actuall doesnot exist", I also tried % and _ as wildcards but neither has worked.. Any idea how to do this in VC++.. It is really painful to enter the file names one at a time especially when you know there might be more than 70 files per run.
