pywin32实践 判断程序窗口是否失去响应

有时候windows程序会出现”卡死”的情况，在任务管理器中一目了然。那么问题来了，万一程序在后台或者远程运行，要如何知道程序是否未响应呢？这里分享一个利用pywin32的实现方法。

获取windows窗口对应的进程ID

hWndList = []# 获取窗口句柄win32gui.EnumWindows(lambda hWnd, param: param.append(hWnd), hWndList)# 迭代for hWnd in hWndList:    # 获取窗口句柄对应的线程ID和进程ID    threadId, process_id = win32process.GetWindowThreadProcessId(hWnd)    print(threadId, process_id)

获取进程名和进程ID

# instance表示进程实例(可重名)junk, instances = win32pdh.EnumObjectItems(None, None,'process', win32pdh.PERF_DETAIL_WIZARD)proc_ids=[]proc_dict={}for instance in instances:    if instance in proc_dict:        proc_dict[instance] = proc_dict[instance] + 1    else:        proc_dict[instance]=0for instance, max_instances in proc_dict.items():    for inum in range(max_instances+1):        hq = win32pdh.OpenQuery()        path = win32pdh.MakeCounterPath( (None,'process',instance, None, inum,'ID Process') )        counter_handle=win32pdh.AddCounter(hq, path)         win32pdh.CollectQueryData(hq)        type, val = win32pdh.GetFormattedCounterValue(counter_handle, win32pdh.PDH_FMT_LONG)        proc_ids.append((instance,str(val)))        win32pdh.CloseQuery(hq) proc_ids.sort()

判断窗口是否未响应

# 迭代进程IDfor i in range(0, len(sys_ids)):    # 匹配进程ID和进程名    if(sys_ids[i] == process_id and process_name == proc_names[i]):        # 判断窗口状态        status = checkStatus(hWnd)        status_list.append(status)status_code = -1if(len(status_list)>=1):    status_code = set(status_list).pop()
