Which DOS command are you looking to run from your c++ code?

The system()[^] command can be used to execute an operating system function. Also read about it here[^]. You could also use CreateProcess[^] if you are wanting to execute a program

If you just want to run a command from you application, go fot the functions mentioned in earlier reply. If you are aiming to run a command and show its output in a window in your application, you have to go for Pipe communication.

C WinAPI solution (you can adopt it in mfc easily i think):

#include <windows.h>
#include <stdio.h>

char * ExecuteCMD(char * command)
{
SECURITY_ATTRIBUTES sec;
PROCESS_INFORMATION pi;
STARTUPINFO si;
HANDLE hOutR, hOutW;
DWORD BTAvail;
char * Result = NULL;
char * cmdline = NULL;
char cmdpath[256];
OSVERSIONINFO OSVersionInfo;
DWORD Read = 0;

		ZeroMemory(&pi, sizeof(PROCESS\_INFORMATION));
		ZeroMemory(&sec, sizeof(SECURITY\_ATTRIBUTES));
		sec.nLength = sizeof(SECURITY\_ATTRIBUTES);
		sec.bInheritHandle = TRUE;
		sec.lpSecurityDescriptor = NULL;

if (CreatePipe(&hOutR, &hOutW, &sec, 0)) 
{
			ZeroMemory(&si, sizeof(STARTUPINFO));
			si.cb = sizeof(STARTUPINFO);
			si.hStdOutput = hOutW;
			si.dwFlags = STARTF\_USESTDHANDLES|STARTF\_USESHOWWINDOW;

		cmdline = (char \*) GlobalAlloc(GMEM\_FIXED, (7 + lstrlen(command)));
		lstrcat(lstrcpy(cmdline, " /a /c "), command);

		OSVersionInfo.dwOSVersionInfoSize = sizeof (OSVERSIONINFO);
		GetVersionEx (&OSVersionInfo);

		if (OSVersionInfo.dwPlatformId == VER\_PLATFORM\_WIN32\_NT)
		{
			GetEnvironmentVariable("ComSpec", cmdpath, 2048);
		}

	if (CreateProcess(cmdpath, cmdline, &sec, &sec, TRUE, NORMAL\_PRIORITY\_CLASS, NULL, NULL, &si, &pi))
	{
		WaitForSingleObject(pi.hProcess, INFINITE);
		CloseHandle(pi.hThread);
		CloseHandle(pi.hProcess);
		PeekNamedPipe (hOutR, NULL, 0, NULL, &BTAvail, NULL);
			if (BTAvail > 0)
			{
				Result = (char \*) GlobalAlloc(GMEM\_FIXED, BTAvail + 1);
				ReadFile(hOutR, Result, BTAvail, &Read, NULL);
				Result\[BTAvail\] = '\\0';
				OemToChar(Result, Result);
				return Result;
			}
	}

}
return NULL;
}

int main(int argc, char **argv)
{
char *cmd = ExecuteCMD("dir");
puts(cmd);
}
