Re: How to add .h file(Header file) in c#

You don't and can't use a header file in C#.

One of the advantages of using C# over C++ is precisely the fact that it doesn't use header files.

You can only use C++ header files indirectly in C# by referencing a C++ library,
which allows you to access anything declared as public in the header files
that were compiled into it.

Use the C preprocessor, but the code had better be valid C#.

Importing a WCF method into WP7 App becomes async and doesnt return the list.

I am new to creating WCF projects as well as windows phone 7.

I created a simple method in WCF which just returns a list of an object.

public List<Sticky> GetSticky()
{
    return stickys;
}

I then used it very simply

Sticky[] test = client.GetSticky();

When I import the WCF dll via a service reference into a console app the method acts how it should. When I import the method into a Windows Phone 7 application it become an async method (not sure what this means)and doesnt return a list, it comes up void.

client.GetStickyAsync();

If anyone can help explain what is going on and help me to be a little less confused.

Thanks

Hi all ,

i need a help that i need to import excel to the sql database.
i saw the examples of doing the same, but the thing is that the columns in the excel will get change dynamically. So i want to do as like in SQL import and Export data doing.
It will create the table with respect to the excel (also we have option to choose our own table and map the columns).Like that i need to create the table with respect to the excel every time when i do import . What method should i use, Please help me.

Thanks in advance.

System.Data.IDataReader dr = db1.ExecuteReader

db2.CreateTable ( args [ 3 ] , dr ) ;

db2.InsertData ( args [ 3 ] , dr ) ;

I'll leave the rest as an exercise. Cool | :cool:

Have a look here:

You will need to get the time from an internet time server. Otherwise you can't be sure if the time of the local pc was changed.

If you don't have internet connection, then you won't have a chance of detecting a changed system time. At least I can't think of any reasonable way. Sorry.

As far as I'm aware, your requirement is impossible: You either use the system clock, or use an external one.

If an Internet clock isn't good, you could use one of the following:
This (it works in Europe) that syncs with the atomic clock signal: http://www.lindy.co.uk/usb-precision-clock/20984.html[^]or http://www.atomicclockrugbymsf.co.uk/ntp-time-server/atomic-clock.html[^]
Or You could also sync with the clock in a connected GPS system, I think these need to be accurate

i hope there should be some way other than using external clock..
coz applications like photoshop and all runs only 30 days ..
even if we change the system time

The photoshop will store the latest system date it has run, if you wind back the clock before windows starts, my guess is you get a free copy of photoshop Smile | :)

There are a few things Photoshop possibly does to help with the problem:

It could "calls home" to get the time off a server as well where an Internet connection is present?

It might keep track of how long it has been running, to make sure it doesn't exceed the limit (e.g. 30 days continuous execution).
Some cleverer algorithm, where it keeps track of when it was used, if the current date time is before the latest used date it does something

I know I've fallen foul of point three, when doing some system date specific testing: the software thought I was spoofing the date, so it ended the license immediately.

They use rather more sophisticated algorithms, and detect such things as the system clock having been wound back; there are things that can be done to check to see that the time is different to what is should be.

Not necessarily, see my post to the lounge (http://www.codeproject.com/Lounge.aspx?msg=3558840[^]) which shows real data proving the inaccurateness of a GPS unit clock.

Well, if the clock on the PC is wrong and you have no internet connection, its going to be hard to know what the time is. Impossible perhaps. What you do have is Environment.TickCount, which is the number of very small 'ticks' (order of tens of nanoseconds I think) since start up. If you know the time is correct when you start up, you can use this and a bit of maths to keep telling the correct time even if the clock changes.
