我想做一个程序,打开一个 Windows 资源管理器窗口,等待 5 秒,然后关闭窗口。我尝试了以下方法:
#include "stdafx.h"
#include <windows.h>
#include <string>
#include <sstream>
#include <iostream>
using namespace std;
void _tmain( int argc, TCHAR *argv[] ) {
STARTUPINFO si;
PROCESS_INFORMATION pi;
ZeroMemory( &si, sizeof(si) );
si.cb = sizeof(si);
ZeroMemory( &pi, sizeof(pi) );
if( argc != 2 ) {
cout << "Usage: " << argv[0] << "<path>";
return;
}
// Build the command string.
wstring app = L"explorer.exe ";
wstring str_command = app + argv[1];
wchar_t* command = const_cast<wchar_t*>( str_command.c_str() );
// Open the window.
if( !CreateProcess( NULL, // No module name (use command line)
command, // 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
) {
cout << "CreateProcess failed: " << GetLastError();
return;
}
cout << "Opened window!" << endl;
// Wait for it.
Sleep(5000);
cout << "Done waiting. Closing... ";
// Close explorer.
HANDLE explorer = OpenProcess(PROCESS_TERMINATE, false, pi.dwProcessId);
if( !explorer ) {
cout << "OpenProcess failed: " << GetLastError();
return;
}
if( !TerminateProcess( explorer, 0 ) ) {
cout << "TerminateProcess failed: " << GetLastError();
return;
}
// Close process and thread handles.
CloseHandle( explorer );
CloseHandle( pi.hProcess );
CloseHandle( pi.hThread );
cout << "Done.";
}
我让它打开得很好,但我不能让它关闭。TerminateProcess 失败,错误代码为 5。我还尝试将 WM_CLOSE 消息发布到窗口。我从中获得了成功的价值,但窗口保持打开状态。
请帮忙!
