the system() function

yanghui1023

I've used the system funtion in stdlib.h but when I use it to run an executive file,the DOS window appears.How can I remove the DOS window?

eg,I've achieved a player and a caculator& and a dialog with 2 buttons,when I click button1,then I want the player appear,and so dose with the caculator when I click button2.So in the message process funtion of button1 I used system() to run the executive file of player.
the main code is:

void CProjectDlg::Onplayer()
{
// TODO: Add your command handler code here
system("player");/* player is the name of the player's
executive file */
system("exit"); // i want to exit from dos window bu failed.
}

void CProjectDlg::Oncaculator()
{
// TODO: Add your command handler code here
system("caculator");
system("exit");
}

Is anyone knows how to remove the Dos window thanks.

http://www.google.com/ always works It also helps to have a copy of the Win32 API help files on you computer, if you can't get onto msdn all the time. I got mine somewhere on the site for mingw...you can search it out, I'm sure.
