创建进程是编程开发的常用操作。Windows中的创建进程采用API函数CreateProcess实现。下面是一个使用例子：

#include <Windows.h>#include <string>int _tmain(int argc, _TCHAR* argv[]){STARTUPINFO si;PROCESS_INFORMATION pi;ZeroMemory( &si, sizeof(si) );si.cb = sizeof(si);ZeroMemory( &pi, sizeof(pi) );std::string strCmdLine = "ping www.baidu.com"; // Start the child process. if( !CreateProcess( NULL,   // No module name (use command line)(LPSTR)strCmdLine.c_str(),        // Command lineNULL,           // Process handle not inheritableNULL,           // Thread handle not inheritableFALSE,          // Set handle inheritance to FALSE0,              // No creation flagsNULL,           // Use parent's environment blockNULL,           // Use parent's starting directory &si,            // Pointer to STARTUPINFO structure&pi)           // Pointer to PROCESS_INFORMATION structure) {printf( "CreateProcess failed (%d)\n", GetLastError() );return 1;}// Wait until child process exits.WaitForSingleObject( pi.hProcess, INFINITE );// Close process and thread handles. CloseHandle( pi.hProcess );CloseHandle( pi.hThread );   getchar();   return 0;}

使用上面的方式创建进程会出现一个控制台界面。要隐藏这个控制台界面，只需要将CreateProcess函数的第六个参数设为CREATE_NO_WINDOW，比如上面对应的代码应改为：

if( !CreateProcess( NULL,   // No module name (use command line)(LPSTR)strCmdLine.c_str(),        // Command lineNULL,           // Process handle not inheritableNULL,           // Thread handle not inheritableFALSE,          // Set handle inheritance to FALSECREATE_NO_WINDOW,              // No creation flagsNULL,           // Use parent's environment blockNULL,           // Use parent's starting directory &si,            // Pointer to STARTUPINFO structure&pi)           // Pointer to PROCESS_INFORMATION structure) {printf( "CreateProcess failed (%d)\n", GetLastError() );return 1;}
