You need to calculate the total degrees first:
Basically:
D = d + m/60 + s/360
Where
D = full degrees,
d = degree of your co-ordinate.
m = minutes of your co-ordinate.
s = second of your co-ordinate.
The to convert to radians:
r = (PI * D) / 180.
The miliradians is r * 1000.
The main things you are likely to run up against are:
1. Precision errors in the maths. You can re-work the formulae I have given you to help.
2. The problem that the Earth isn't a true sphere, it is flattened at the poles. Calculating distances on a non-true sphere is beyond my capabilities at the moment....Dalek Dave: There are many words that some find offensive, Homosexuality, Alcoholism, Religion, Visual Basic, Manchester United, Butter.

Now you tell you want milliradians. I thought you want to use Miles as in distance.
For 1 Degrees, it comes about "17.452" MILS. To convert Degres, Minutes and seconds use the folowing code:
Double dec = degres + (minutes/60) + (seconds/3600)
Double mils = dec * 17,452

See http://en.wikipedia.org/wiki/Angular_mil[^]
You need some more information before you can convert. Which definition of mil do you want to use?
Decide which unit definition you really want and apply the appropriate formula. You can convert seconds to degrees by dividing by 3600 and minutes to degrees by dividing by 60.

right. see also here[^].
1 circle = 6400 mils.

Actually it's not quite so simple:
- 1⁄6400 of a circle in NATO countries.
- 1⁄6283 The “real” trigonometric unit of angular measurement of a circle in use by telescopic sight manufacturers.
- 1⁄6000 of a circle in the former Soviet Union and Finland.
- 1⁄6300 of a circle in Sweden.

I want to use 1 degree=17.777777778 mils and i can convert seconds, min to degrees and then to mils.
But i dont know actually regarding the directions which will be specified along with the degree values in the lat/long.
I need to convert the lat/long values to mils. The lat/long values will have N,NE, and so on specified. So, do i need to take those things into consideration after i finish the conversion from deg to mils???

|
|
|
|
Well, E/W and N/S are just sign indicators. Usually N and W are negative lat/long respectively and S and E are positive. Just do the normal calcs and use the N/S/E/W with the absolute values depending on the sign of the result.

Hi,
I have a C# program that I would like to sell and I want to offer a 14 day trial, I understand that all piracy prevention schemes are overcome so I don't want to waste much time doing this. Could anyone offer any suggestion and even some sample code?
thanks in advance......

This will explain how to get unique key. And you can use it with algorithm to get serial key. If you do not wan't to protect then my suggestion is a Demo mode. You have limited functions, and when someone bought it, they get to download full version.
Any approach you take, it will be pirated.

Hi Group members,
I have a problme here...
I have an NT service which i am using as an asynchronous scheduled job in a remote server.
I wish to convert it into a webservice, to make it synchronous, and expose it to the clients, with an ease...
Can some one suggest what would be the right approach to start with??
The NT service is written in the .NET platform.
I think it's a good challenge open for the group...
|
|
|
|
|
Depending on how your original service was written, you may be able to reuse parts of the code. But, as a general rule, you'll be rewriting the thing from scratch.
But, since we know nothing of what your existing service is doing, we can't really make any recommendations, or even if a web service is a viable option for what you want to do.
|
|
|
|
|
well, it is written earlier as a VB.NET scheduled job... then we made it as a .NET NT service...
When u say some part can be reused, i believe that's about the logic part...
we mght have to change the ways it is triggered and the way it can be invoked... am i right or going wrong?
Well, why webservice, as it's better in the ways that it can be exposed for a larger consuming services, and on gets it can invoke, only when required... unlike the scheduled job...

Absolutely right. You will have to change the way it's triggered. The only way to trigger a method on a web service is to call it from a client over HTTP. This will require you to write an app that will call the web service and probably launch that as part of a scheduled job. Oh, wait. You just ended up back at where you started from making all of this a moot point.
Granted, you get the ability to pass parameters to the web service method call and call it any time you want. But, you have to understand how web services work, security implications and how they relate to what your service is doing, the accounts and limitations that the web service runs under, impersonation may be required, depending on your requirements, and in that case, user authentication issues, ...

Thanks Dave,
for taking time and helping me in analyzing this issue.
Let me do a prototype of what i want through what i know, and have learnt from u and other online resources.
I would need your help in future too...
about your concern, as it's going to be an internal application, not exposed to www, we might not have to worry about security implications...
But, yes, other doubts and concerns are valid and should be thought upon...
Thanks,

Hello all and let me explain my problem briefly in Windows Forms application.
If any of you read Julia Lerman`s book, i am basicly implementing the techniques that are explained there but one thing i couldn`t solve. To make it simple i have two tables with one to many relationship, like customer and address. I add the customer to the datasource and change the address navigation property to combobox.
I drag name, surname and adress to the Forms. This is how i do databinding
CustomerEntities context = new CustomerEntities();
List<adress> myadresses = context.addresses.ToList();
CustomerBindingSource.DataSource = context.customers.Execute(System.Data.Objects.MergeOption.AppendOnly);
AddressBindingSource.DataSource = myaddresses;
Now as the book says i set the datasource of the addreess combobox to AddressBindingSource in UI then set displaymember, value and selectedItem.
Everything works fine except that display member of the combobox doesn`t display porperly. It diplays as MyAppName.Address, meaning object itself..What am i missing please help me

|

Not sure I fully understood your needs. But try to override the ToString() method in order to select what's you want to display.
|
|
|
|
|
Thanks, i override the tostring method of the entity object to get the work done..When i use listbox nothing is needed to display correctly but with texbox this is needed i guess, thanks again

I have one application that we lost the source code to that I'm rewriting and another app I'm writing to help a business partner that I started yesterday.
I created a class project, removed the Class1 library, then added the Linq to Sql class type.
So far so good.
I added my tables and queries and rebuilt the application to start coding.
But when I start my normal process using (MasterContext context = new MasterContext()){} I keep getting the error that the context cannot be converted to IDisposable. WTF???!!!!
I've done everything I can think of but I keep getting this error. Also if I get rid of the using a write a select, the variable used in the from statement refuses to expand. Now I know that is usually a sign that I've screwed something up, but I cannot see what it could possibly be.
Any input would be greatly appreciated.
Michael

Does MasterContext implement IDisposable? If not you can't have it in a using
|
|
|
|
|
You must not know anything about Linq to Sql. MasterContext in a Linq to Sql class inherits DataContext which implements IDisposable. Also the documentation for Linq to Sql has almost the first line stating you should always use using() when creating a DataContext.
|
|
|
|
|
You're right, I don't know anything about Linq to SQL 
|
|
|
|
|
System.Data.Linq.DataContext implements IDisposable, so MasterContext will too if it subclasses System.Data.Linq.DataContext. Check your inheritance hierarchy (not forgetting partial class files). It is also possible that something has gone wrong in auto-generation, if all else fails, I suggest is a restart (which fixes a surprising number of the odder problems).Dalek Dave: There are many words that some find offensive, Homosexuality, Alcoholism, Religion, Visual Basic, Manchester United, Butter.
