how convert cdTime to TDateTime(Delphi) or CTime(VC)?

[bluechos]

hello, All !

please help me.

I taked the shooting time by SDK API
but I can not convert cdTime( this is unsigned Integer)
to Delphi Datetime or C Datetime.

How can I get the datetime?

please...

bluechos,

I can't see you getting a Date/Time from an unsigned integer (unless there is more to cdTime). More likely is that you can get a Date only.

If cdTime is a unsigned integer, probably 32-bit you are looking at using Cardinal or LongWord in Delphi (both are the same).

You can simply cast these to a TDateTime:

var
cdTime: Cardinal;
myDateTime: TDateTime;
begin
cdTime := 32767;
myDateTime := cdTime;
end;

So you could get a Date, but as I say, you won't get a time unless the cdTime unsigned integer has some kind of special decoding rules outlined in the SDK (which I don't have).

Cheers

well since the documentation is a bit lacking ...
try FileDateToDateTime and see if it gives a sensible result

eventually got round to looking at this ...

use UnixToDateTime

:) Been using Delphi since the year dot and it still surprises me with stuff I didn't know that was in there.
