SystemParametersInfo() 设置无法激活屏幕保护程序，错误代码 = 329

在Windows登录过程中，我尝试激活屏幕保护程序：

ret = SystemParametersInfo(SPI_SETSCREENSAVEACTIVE, state, NULL, 0);

当我使用GetLastError()时，它返回329；我在MSDN上找到：

如果机器进入省电模式或系统锁定状态，则会出现ERROR_OPERATION_IN_PROGRESS异常。

所以我改变了代码：

int loopNum = 10;
do{
    ret = SystemParametersInfo(SPI_SETSCREENSAVEACTIVE, state, NULL, 0);
    if(!ret){
loginfo("[set_screensave_active] set screensave active status to 1 failed, gle = %d",Getlasterror());
}
    Sleep(1000);
}
while(loopNum--);

我确信Windows登录需要很短的时间。

当我登录 Windows 时会触发此代码。有时会报错329，10次循环全部失败！

日志如下：

在8:58:33中，我开始登录Win10。并且，在8中： 58:35，我登录了Win10。每秒调用一次API SystemParametersInfo，持续十秒。 8:58:36之后，系统不再处于锁定状态。但 SystemParametersInfo 也返回错误代码 329。

原文

During the Windows login process, I try to activate the screensaver:

ret = SystemParametersInfo(SPI_SETSCREENSAVEACTIVE, state, NULL, 0);

When I use GetLastError(), it returns 329; I found on MSDN:

If the machine has entered power saving mode or system lock state, an ERROR_OPERATION_IN_PROGRESS exception occurs.

So I change the code:

int loopNum = 10;
do{
    ret = SystemParametersInfo(SPI_SETSCREENSAVEACTIVE, state, NULL, 0);
    if(!ret){
loginfo("[set_screensave_active] set screensave active status to 1 failed, gle = %d",Getlasterror());
}
    Sleep(1000);
}
while(loopNum--);

I'm sure that Windows login takes a short time.

This code is triggered when I login to Windows. Sometimes the error 329 is reported, all 10 times the loop fails!

The logs are as follows:

In 8:58:33, I began to logon the Win10.And, In 8:58:35, I logined the Win10.The API SystemParametersInfo is called every second for ten seconds. After 8:58:36, the system was not in lock states. But SystemParametersInfo also return error code 329.
