You can't. C# has no concept of a header file. You need to create a class or struct.

Please at least look at some documentation on the language before you try using it.

Add a C++ project to your projects. In the C++ project, create a class implementing the header file's methods and properties, then reference that C++ project from your C# projects. That's a few steps more complicated than we would like to have it, but it is feasible.

As Mark says, you can't.

You will need to recreate all the functions prototypes and constants in a C# class. Any structures that are used will also need to be recreated. You will need to make use of the contents of the System.Runtime.InteropServices[^] namespace.

You may find www.pinvoke.net[^] useful as most of the Windows things have already been done there.

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

System.Data.IDataReader dr = db1.ExecuteReader
(
    "SELECT * FROM [" + args [ 2 ] + "]"
) ;

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
