Hi,
IFAIK there is no code for getting the public IP address; what you need is a web page that
provides you such information, such as http://www.perceler.com/getipadr1.php[^]
You could use HttpWebRequest.GetResponse() to use it programmatically.

Prompt the user to turn back. Use a web cam to quickly take a snap of it and we can extract the IP address from the image.

Hi, beginner programmer here, first post
I am writing a program that uses a arraylist of class part, and class Car consists of
Public Class Part
Public name As String
Public price As Double
End Class
Public Class Car
Public name As String
Public parts As New ArrayList
End Class
There is an ArrayList of Part and I would like each Car to consist of various Parts and the price would be totaled for a Car etc.
I would like to be able to change the price of a Part and if a Car contains that part I will be able to retotal the new amount.
By using something like
Car.parts.Add(partArraylist.Item(i))
Am i adding a copy? reference?
Any advice would be great, or am i approaching it the wrong way?
Thanks

Unless you're using VB 1.0 or 1.1, you should never use the arraylist class. Although I guess in VB it doesn't matter b/c the language is weakly typed, but ideally you should use generic collections such as List<Car> ( I think it's List(Of Car) in VB ).

If Part is a class, you're adding a reference, if it's a struct, you'd be adding a copy. So, yes, you could do that, and then change the price of the part, and all the cars with that part, should reflect the new price. Then you can have a method in the car that iterates over it's parts, adds them, and comes up with a total.
What if a car has more than one of the same part ?

Thanks for the reply, very helpful, forgot all about generics.
Yes a car is able to have more than one part, ie 4 wheels. Havent thought how to implement it yet, could I do something like,,
Public Class Car
Public name As String
Public parts As New List(Of Part)
Public quantity As New Hashtable
End Class
And have the key as the partname and the value for quantity?

Now you have forgotten about generics again. 
Public Quantities As New Dictionary(Of Part, Integer)
An alternative would be to create your own generic class Qantified(Of T), that just contains an Integer for quantity and a T variable. Then you could do:
Public Parts As New List(Of Quantified(Of Part))
Despite everything, the person most likely to be fooling you next is yourself.

hi
how can i detect a connection string in a program?
i want to detect a connection string in a program and find the database that the program connect to it.
i am writing a program that when it add to other program with sql database it must detect the connection string and the database that the program connects to it... please help me...
|

well, this sounds nasty, but, really what you want to do is load the whole program and it's config files as binary data, then go through it looking for something that matches a regex designed to find connection strings.

i thik that your way is difficult... isnt there any way to answer this question? all the databases are sqlserver

Well, you could use black magic I suppose.
You have a binary file and you want to find connection strings in it. How do YOU propose to do that ? You MAY be able to write code that detects attempts to connect to a SQL Server, and find them that way. A more obvious approach is to look for SQL Servers that can be seen and then look to see what DBs they have, that would be a ton easier. It won't tell you which DB belongs to which program, obviously.

File.ReadAllBytes. Getting those bytes into strings that you can then run a regex on, is another matter. I guess you need to look for sequences that look like a string. I think the whole thing is a disaster. I assume you're assuming that the string is not in a config file, seeing as you're trying to hack into an existing program.

Your boss gave you one night to write something, but when it's explained to you, you can't understand the explanation ? Your boss is an idiot.
I've explained every possible way to do this that I can think of, in the plainest possible language. I don't know what else to say.

Hey guys,
Is there any body that worked on archive? Right now I am working on small application, which does the archive and the code was written in vb.net. It copies the database and zip that file and send that zipped file to write a DVD. This application works fine for small file but its giving error when we have data like 5 GB its giving error as below
ICSharpCode.SharpZipLib.Zip.ZipException: Maximum entry size exceeded
If any body can help, it will be grate …….appreciate your time. Thank you………

You should create a multi part zip, not a single 5 gb file.

As Christian has said, do multi-part file and just have a way to be able to work with all the parts when unzipping.

Not sure whether to put this query into the database section or here, but here goes.
I have a SQL Server database with a table of contacts (about 130,000 records). Each contact is a member of a category (9 different categories). What i need to do is count how many contacts are in each category for output in my vb.net application.
I can think of 2 methods to do this (actually 3 but the third is a definate no), which would you recommend.
Method 1 : Use a Cursor in a SQL Server stored procedure to iterate through all the contacts keeping a count of contacts in each category.
Method 2 : Get the data from the database and do the processing in my application.
Which approach do you think would ofrer the best performance?
(In case you were wondering, the 3rd method involves calling a stored procedure 9 times, once for each category and doing the count)
