C ++ WMI结构数组 [英] C++ WMI Struct Array
问题描述
我正在研究可与WMI一起用于多个设备的某些结构数组，例如CPU，内存，硬盘驱动器等.我遇到了一个桥梁，我似乎无法跨越...
基本上，我使用WMI并查询"Win32_LogicalDisk"以收集可用空间，大小等，并将其备份到数组中.我的问题是我的SmartStatus. "Win32_LogicalDisk"中的状态为空，因此我无法在此处查询.但是，"Win32_DiskDrive"中的状态不是空白，但不包含驱动器号或可用空间.因此，我确实需要同时查询两者.
我需要做的是将从"Win32_DiskDrive"->状态"查询中获得的结果添加到数组中的数据中.
我不好解释，但是第一个查询会像这样添加到数组中:
Hi,
Im looking into some struct array work with WMI for multiple devices, such as CPU, memory, hard drive etc... and i''ve come accross a bridge i can''t seem to cross...
Basically im using WMI and querying "Win32_LogicalDisk" to gather freespace, size, etc... and backing this up to an array. The problem i have is with my SmartStatus. The Status in "Win32_LogicalDisk" is blank, so i can''t query this here. The Status in "Win32_DiskDrive" however is not blank, but doesn''t contain drive letters or free space. So i do need to query both.
What i need to do is add the result i get from the query on "Win32_DiskDrive"->"Status" to the data in array.
Im bad at explaining but the first query will add to the array like so:
3
C:
<- BLANK
19658754
11235
60%
第二个查询将找到状态"，我需要将其添加到上面的空白区域，因此当我将结果打印在那里时.
代码:
Second query will find "Status" and i need to add it to the above Blank area, so when i print the result its all there.
CODE:
struct DriveInfo
{
int nType;
char DriveLetter[10];
char SmartStatus[50];
float TotalSpace;
float FreeSpace;
float PercentFree;
};

推荐答案
您似乎已经对此进行了编码，因此在"DriveList"中仅得到两个条目.
您可以将它们拆分为单独的记录.
或者只是删除for循环并更改日志行:
It looks like you''ve coded this so that you only get two entries of in ''DriveList''
You might split those into separate records.
Or just remove the for loop and change the log line:
Tools.Log( "Drive %s\\ has a status of \"%s\". %.0fGB Free Space, %.0fGB Total Space. %.0f%% Free Space",
CurrentDrive[0]->DriveLetter,
CurrentDrive[1]->SmartStatus,
CurrentDrive[0]->FreeSpace,
CurrentDrive[0]->TotalSpace,
CurrentDrive[0]->PercentFree
);
虽然看起来很乱.我可能会将信息分成两个名称不同的变量，以明确表示它们的含义.
It looks messy though. I''d probably split the info into two variables with different names, to be clear on what they represent.
