I'm looking to add namespaces to my project, but am confused about some technicalities.
Situation
- I have a number of normal .h and .cpp files for each class.
- To the top of the .h files I've added (with corresponding close brackets):
<br />
namespace proj {<br />
namespace data {<br />
- To the top of the .cpp files I've added
<br />
using namespace proj::data;<br />
- I've got the additional using namespace Xfor lower-level namespaces.
This is all okay, but namespaces do not lead to compiler visibility, so I still need all the #includes I used to have.
Potential Solution?
I've started creating .h files to include all the classes in a namespace, so you get something along the lines of:
<br />
#include "ns_proj_data.h"<br />
...<br />
using namespace proj::data;<br />
As I put all the files back into my project, I can foresee a situation where I need to be careful about these #includes to know exactly what files are going where.
Question:
Do other people use namespaces like this, or am I getting the wrong end of the stick?
Should I just ditch the idea of namespaces and just use the #includes I've used for years?
Thanks for your time,
Dave.

Sure.
Namepaces do not need to visibility, they lead to invisibility.
They are a tool to allow programmers to have several classes name CProperty in their Project.
One in the namespace Widget and one in the Namespace Thingie.
You then tell the comoiler (via direct :: notation or via using) which class you want to use.
The compiler still has to know the declarations of the Classes to use them.
Let's think the unthinkable, let's do the undoable, let's prepare to grapple with the ineffable itself, and see if we may not eff it after all.

I need to convert DWORD to Date time. Can any one suggest me

Please detail.

I have a DWORD value 524642425 I need to see this value in Date Time
Can i know how to use to get the value using COleDateTime.

OK. But what does it represent (i.e. How did you obtained it? Is it the result of any API call?)?

What CPallini wanted to know (I suppose) is how is your date coded into your DWORD ?
|
|
|
|
|
Yes I using a dll the DWORD is return from that dll and the Datetime is coded in that value.I want to check that date and time in vc++
|
|
|
|
|
 Please try to understand what we are asking before replying.
How is the date encoded in the DWORD ? In other word, what does a digit represent ? A second, a milisecond, ... ? To which date correspond the 0 value ?

Now, I suppose he doesn't know.

Indicates in 100-nanosecond intervals the stop time of this sample.
The above mention is the sdk document we have regarding the DWORD

Finally!!!!

I strongly doubt that it is the SDK's reference of DWORD (i.e. please indicate the function to which SDK help actually refers).
Your number represents roughly 52 seconds, what conversion do you need?

GetTickCount returns a number of miliseconds, not a number of 100-nanoseconds.
|

Actually 100-nanosend intervals are recorded inside FILETIME struct, hence functions like GetSystemTimeAsFileTime are possible candidates.

This is fun! Can I have a turn guessing at what function he used to get the value? Pleeeeeezzzz, it's urgent!

Yes, now it's your turn. Turn ended (do you realize we're talking about 100-nanosecond intervals? It is fu****g urgent!!!!).

Based on the limited information you've provided, I'd go with something like:
DWORD dw = 524642425;
Date time dt = dw; ;) Now if you want a more helpful, detailed answer, please rethink your question. Ask yourself something like, "What does 524642425 represent?" Is it the number of seconds since the start of time, or the number of milliseconds since Windows was last started, or the number of nanoseconds since the start of the year, etc?

So you assume thinking was previously involved eh? Interesting.

A nanosecond is one billionth of a second. If you are storing Time in a DWORD represented as 100 nanoseconds then you would not be able to store very much time. a DWORD is a32-bit unsigned integer (0 through 4294967295).
You are probably recieving a FILETIME structure:
http://msdn2.microsoft.com/en-us/library/ms724284(VS.85).aspx[^]
If for some reason you are actually using a DWORD then you can get seconds like this and work from there.
DWORD dwTime = 524642425;
DWORD dwSeconds = (dwTime/10000000);
