datetime

[Maejie]

I am looking into some WMI class, there are properties of type "datetime"

class win32_something
{
//...
datetime dt;
//..
};

What type is that 'datetime' equivalent to in C library ?

Thank you

Well, I never used WMI but according to its documentation (http://msdn.microsoft.com/en-us/libr...37(VS.85).aspx) the datetime is formatted as:

yyyymmddHHMMSS.mmmmmmsUUU

I guess there is no any "equivalent" in C library but you could format such a value using sprintf or some similar function.
How are you going to use this "'datetime' equivalent to in C library"?

Hi, thanks for your reply
Here is my code I try to read Win32_OperatingSystem's install data

pClassObject->Get(L"InstallDate",0, &vtProp, CIM_EMPTY, 0);
BSTR str=vtProp.bstrVal;

ISWbemDatetime*o;
//Create o's instance
o->putval(str);
// do somethingelse


While debygging I sse the value of str is something like
{aaaa-aaaa-zzz-eeee-eeeee}
What happens ?
I expect a time format string from Get method as you mentioned though.

I have no idea where you have got such a value from (and how!) - it looks almost like a GUID value except the lenthes of fields you supplied are not correct...
Anyway you could also look at this MSDN site.

The InstallDate property in win32_operatingsystem is of type datetime, I am thinking the Get method from classobject pointer should result a string of double type indicating the date and time of the installation. Yes, it results in an odd GUID string.
