What would i use to say if no text is entered in textbox1, then ... also what would i use to make a sure the user choose one or the other radio button? for example i also have a combo box, i used "If SubjectComboBox.SelectedIndex <> -1" for the if statement.

Using the code below i will get all network interfaces wich are enabled and functional on the machine.
Private netIntrfc As NetworkInterface() = NetworkInterface.GetAllNetworkInterfaces()
For i As Integer = 0 To netIntrfc.Length - 1
If netIntrfc(i).OperationalStatus = OperationalStatus.Up Then
[code]....
But my problem is how to get the default one, the one(ethernet adapter) through wich user is connected to internet?I need to change some settings of default(through wich user is connected to internet) adapter. settings i change through registry so i could sample add same settings for each network interface but that could cause problems and makes no point then?
EDITED:for now i have done like code below, so if this can help someone other...
Dim u As UdpClient = New UdpClient(System.Net.Dns.GetHostName, 1)
Dim localAddr As IPAddress = CType(u.Client.LocalEndPoint, IPEndPoint).Address
Private netIntrfc As NetworkInterface() = NetworkInterface.GetAllNetworkInterfaces()

I am making an application where a user can store their logons/passwords and other details for websites on the internet.My question is this: Am I able to have a list of all sites that the user has saved a password for on the internet?I don't think I will be able to get the password (because of Windows security), but am I able to see what sites the user has saved their password on, and maybe even the username they used?

Code is as under:
Imports SHDocVw

I need to make a web browser that uses my home internet connection from anywhere.I plan to have the web browser connect to my router/computer where it will request the desired web pages and have the page data sent back to the browser client. The browser must only have a connection with my IP, and not request the web pages from their web URL.How can i do this and what will i need to set up on my home computer?

I've added a database to my application with 2 fields:"ip" address and "started" that holds the number the application was started from that specific IP.I want to upload the database to my site hosted at google.sites. When the program is started it should make a connection with the following cases:
1-no connection with the database (possible no internet available) - it should display an error message
2-there is connection, the IP is not stored on the database, it addes the IP to the database and the field "started" with the value 1
3-there is connection, the IP is stored on the database, it increments the field "started" by 1

I wrote a 2008express program last month. It worked as planned until 23 Aug when the following message started appearing about 6 seconds after launch, either the exe (which my wife uses) or in debug mode: "Internet Explorer Script Error An error has occurred in the script on this page. line: 42 char: 1 error: object expected [URL] Do you wish to continue running scripts on this page? Yes No"
Internet Explorer is not the default browser - Firefox is. How could IE get into the picture? The message comes up even if the user does nothing. I deleted all commands invoking the browser and all the code relating to accessing the web - still get the message. No line 42 in the entire project refers to accessing IE or the web. If you click Yes or No on the message, everything is OK from then on. What is "this page" the message refers to and how do I get to it to make some change? If I get to "this page", is it possible to make a change? What would make the message come up after over a month of normal use with no changes to the program?

I made a simple application for a website, the site has a IRC-chat and the program should let you close the window (or actually minimize it to the system tray), and then open it from the tray.the problem that occurs, is that I keep getting a Script Error from IE:url...the weird part is that this does not happen when using Internet Explorer on it's own.so it only happens within the WebBrowser Control in the application I made.the application, also, couldn't be more simple, it had just a single window with only a webbrowser control that loads url..., further the program only has a Notification Icon and a Contextual MenuStrip for the Notification Icon.
