可以用CreateProcess
BOOL CreateProcess(
LPCTSTR lpApplicationName,
// pointer to name of executable module
LPTSTR lpCommandLine, // pointer to command line string
LPSECURITY_ATTRIBUTES lpProcessAttributes, // process security attributes
LPSECURITY_ATTRIBUTES lpThreadAttributes, // thread security attributes
BOOL bInheritHandles, // handle inheritance flag
DWORD dwCreationFlags, // creation flags
LPVOID lpEnvironment, // pointer to new environment block
LPCTSTR lpCurrentDirectory, // pointer to current directory name
LPSTARTUPINFO lpStartupInfo, // pointer to STARTUPINFO
LPPROCESS_INFORMATION lpProcessInformation // pointer to PROCESS_INFORMATION
);
以下是一个使用CreateProcess()函数的例子:
void CreateChildProcessAndWaitUntilDone(const AnsiString& strCmdLine)
{
PROCESS_INFORMATION piProcInfo;
STARTUPINFO siStartInfo;
// Set up members of STARTUPINFO structure.
siStartInfo.cb = sizeof(STARTUPINFO);
siStartInfo.lpReserved = NULL;
siStartInfo.lpReserved2 = NULL;
siStartInfo.cbReserved2 = 0;
siStartInfo.lpDesktop = NULL;
siStartInfo.dwFlags = 0;
// Create the child process.
CreateProcess(
NULL,
strCmdLine.c_str(),
NULL, // process security attributes
NULL, // primary thread security attributes
0, // handles are inherited
0, // creation flags
NULL, // use parent's environment
NULL, // use parent's current directory
&siStartInfo, // STARTUPINFO pointer
&piProcInfo); // receives PROCESS_INFORMATION
// Wait for the processs to finish
DWORD rc = WaitForSingleObject(
piProcInfo.hProcess, // process handle
INFINITE);
}
