为什么按照网上说的，我还是不能启动进程啊？

Question

STARTUPINFO   stinfo;   //启动窗口的信息     
PROCESS_INFORMATION   procinfo;   //进程的信息     
if(!CreateProcess(NULL,_T("C:\\WINDOWS\\notepad.exe"),NULL,NULL,FALSE,
 NORMAL_PRIORITY_CLASS,NULL,NULL,&stinfo,&procinfo))
 cout<<jks::GetLastError(); //这是我改进后的，可以将code找到对应的字符串
返回是“内存分配访问无效”但是 system("C:\\WINDOWS\\notepad.exe");没有问题啊请问我错到那？

msdn上的例子：#include <windows.h>
#include <stdio.h>void main( VOID )
{
    STARTUPINFO si;
    PROCESS_INFORMATION pi;    ZeroMemory( &si, sizeof(si) );
    si.cb = sizeof(si);
    ZeroMemory( &pi, sizeof(pi) );    // Start the child process. 
    if( !CreateProcess( NULL,   // No module name (use command line). 
        TEXT("MyChildProcess"), // Command line. 
        NULL,             // Process handle not inheritable. 
        NULL,             // Thread handle not inheritable. 
        FALSE,            // Set handle inheritance to FALSE. 
        0,                // No creation flags. 
        NULL,             // Use parent's environment block. 
        NULL,             // Use parent's starting directory. 
        &si,              // Pointer to STARTUPINFO structure.
        &pi )             // Pointer to PROCESS_INFORMATION structure.
    ) 
    {
        printf( "CreateProcess failed (%d).\n", GetLastError() );
        return;
    }    // Wait until child process exits.
    WaitForSingleObject( pi.hProcess, INFINITE );    // Close process and thread handles. 
    CloseHandle( pi.hProcess );
    CloseHandle( pi.hThread );
}

Answer 2

STARTUPINFO   startupInfo;
memset(&startupInfo,0,sizeof(STARTUPINFO));
startupInfo.cb = sizeof(STARTUPINFO); startupInfo.dwFlags |= STARTF_USESHOWWINDOW;
    startupInfo.wShowWindow = SW_SHOWMAXIMIZED;
 PROCESS_INFORMATION ProcessInfo;
  BOOL bCreate = ::CreateProcess
        (
"C:\\winnt\\notepad.exe",
  NULL,
  NULL,
        NULL,
        FALSE,
        0,
        NULL,
        NULL,
        &startupInfo,
        &ProcessInfo); WaitForSingleObject(ProcessInfo.hProcess,1000000);
MessageBox("调用程序结束!");

感谢各位的帮助现在还有一个问题，就是启动外部进程后，要等它终止主程序才应该继续进行
本来应该用CREATE_SUSPENDED的，但是一用运行就出错，请问是怎么回事？？？
CString cmd;
cmd.Format(" -g -p ANE3FL -dir \"D:\\ansys_file\" -j \"file\" -s read -l en-us -t -d win32 -d1 %f -d3 %f",d1,d3);
char* pcmd = const_cast<char*>((const char*)cmd); STARTUPINFO si;
memset(&si,0,sizeof(STARTUPINFO));
PROCESS_INFORMATION pi;
memset(&pi,0,sizeof(PROCESS_INFORMATION)); CString path = "d:\\Program Files\\Ansys Inc\\v100\\ANSYS\\bin\\Intel\\";
_chdir(path);
CString workpath = "D:\\ansys_file\\"; if(!CreateProcess("ansys100.exe",pcmd,
NULL,NULL,FALSE,
CREATE_SUSPENDED,NULL,
workpath,&si,&pi))
cout<<"error:"<<GetLastError();

Answer 4

CREATE_SUSPENDED??
WaitForSingleObject

Answer 5

STARTUPINFO   stinfo;   //启动窗口的信息     
PROCESS_INFORMATION   procinfo;   //进程的信息 
memset(&stinfo,0,sizeof(stinfo));
if(!CreateProcess("C:\\WINDOWS\\notepad.exe",
NULL,NULL,NULL,FALSE,
 NULL,NULL,NULL,&stinfo,&procinfo))
 cout<<jks::GetLastError(); 
else
cout<<"ok1!"<<endl; if(WAIT_FAILED==WaitForSingleObject(procinfo.hProcess,INFINITE))
cout<<GetLastError(); cout<<"ok2!"<<endl;
getchar();
