MFC开发之多exe时，操作别的exe

A.exe和B.exe

A.exe不能通过双击或者别的方式主动打开，只能通过B.exe调用才能打开

B中

STARTUPINFO si;
				PROCESS_INFORMATION pi;
				ZeroMemory(&pi, sizeof(pi));
				ZeroMemory(&si, sizeof(si));
				si.cb = sizeof(si);

				TCHAR szApp[MAX_PATH];
				_tcscpy(szApp, Path);//Path为地址

				TCHAR szCommandLine[MAX_PATH] = { TEXT("123456") };//传递给A的命令行参数值
				BOOL working = CreateProcess(szApp, szCommandLine, NULL, NULL, FALSE, 0, NULL, NULL, &si, &pi);

				if (working)
				{
					CloseHandle(pi.hProcess);
					CloseHandle(pi.hThread);
				}
				else
				{
					AfxMessageBox(_T("创建失败！"));
					HANDLE hProcess = GetCurrentProcess();
					TerminateProcess(hProcess, 0);
				}

A中：

LPCTSTR lpszCommandLine = GetCommandLine();
if(NULL == _tcsstr(lpszCommandLine, TEXT("123456"))
{
    exit(0);
}
