主要像任务管理器一样查询本地运行的所有进程

进程查看器

void CProcessFileDlg::OnLook()
{
	int n=0;
	m_nList.ResetContent();
	HANDLE handle=CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS,0);	//得到所有进程
	PROCESSENTRY32 pe;
	Process32First(handle,&pe);							//得到第一个头进程
	do
	{
		int index=m_nList.AddString(pe.szExeFile);
		m_nList.SetItemData(index,pe.th32ProcessID);	
		n++;
	}
	while(Process32Next(handle,&pe));
	CloseHandle(handle);
	CString str;
	str.Format("%d",n);
	SetDlgItemText(IDC_STATIC_1,str);
	GetDlgItem(IDC_EXIT)->EnableWindow(FALSE);
}

void CProcessFileDlg::OnExit() 
{
	int index=m_nList.GetCurSel();
	DWORD data=m_nList.GetItemData(index);
	HANDLE hProcess;
	// 打开进程
	hProcess=OpenProcess(PROCESS_TERMINATE,FALSE,data);
	if(hProcess)
	{
	   if(!TerminateProcess(hProcess,0))
	   {
		  CString strError;
	      strError.Format("错误号:%d",GetLastError());
	      AfxMessageBox(strError,MB_OK|MB_ICONINFORMATION,NULL);
	   }
	}
	else
	{
	    CString strError;
	    strError.Format("错误号:%d",GetLastError());
	    if(GetLastError()==ERROR_ACCESS_DENIED)
		   strError=_T("拒绝访问!")+strError;
	    AfxMessageBox(strError,MB_OK|MB_ICONINFORMATION,NULL);
	}
	Sleep(300);
	OnLook();
}
