"Hey ProgrammingKing, How do I add a feature to my program that shows my Internet Connectivity Status that changes when the Status changes?"
Well, It's really simple, All you do is add 1 timer and 1 label.
Heres the code :
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
If My.Computer.Network.IsAvailable Then
[Code].....
A new client has recently asked me to develop a Windows service that will monitor whether or not his server has internet connectivity. The service should log when the connection goes down to Local Only and back up to Internet Access as shown in Network and Sharing Center.
My original idea was to have the service ping a website like google every 5 minutes or so, but I don't know how to retrieve the results of the ping, so I then thought I could code a WebBrowser control into it and write the log entries based on the results of connection attempts from that.
This also seems like a rather impractical idea though, so can anyone suggest the best way to go about this?
How can I check for internet connectivity? I can't use the My.Computer.Network.IsAvailable, because that one returns true also when you only have a local network connection and no internet connection.

View 8 RepliesI saw another forum which discussed how to detect whether a LAN was connected, but I need to know whether my Internet connection from my ISP is up or not (I'm writing a program for day trading, so knowing if my internet connection is down is critical). I know I can simply open a browser in VB and browse to a site and see if it doesn't come back "page not found", but that involves a fair amount of overhead, and if the internet is down, it often takes many seconds to a minute to come back with "page not found". Is there some simple command that will quickly tell me that my internet connection is working? I'm using VB in VS 2008, and currently using XP although I plan to convert to Windows 7 in the next couple months.
View 3 RepliesI need my application to check for internet connectivity on my user's computer. If there is, an image is displayed and if there isn't, a different image is displayed. Here's the code I used to get this to work:

I decided to test this on my own computer by changing my default gateway (thereby making it seem as if I lost connection). But I realized that the code still showed that I was connected. So I'm thinking that it's only checking for connectivity of the interface - which in this case, is my connection to the router (which is true, I was connected to the router).How do I check that the user's PC is actually connected to the internet? I read the article Check for Internet connectivity but it's in C# and I don't understand that.

View 14 RepliesI am trying to verify connectivity from my application to various servers - For now I am only concerned with mail servers... (later SQL etc)Before anyone gets all upset and thinking this is for SPAM - wrong - these are to confirm connectivity from the application for sending logs OR to ensure the SQL conneciton is working appropriately - Those that want to SPAM can do this simply by getting LINUX and doing it for free with ANY mail client (I add this ONLY because MOST SMTP threads go unanswered... which is silly... there are MANY good reasons to work with mail within an application.....)So what I have tried is opening a telnet session, grabbing the output, and going from there...But it is not working.... the output contains nothing specific to the telnet session I initiate - and.... of course from the command prompt manually i DO get the proper responses
[code]...
I get the command prompt header, I see the commands... I see the prompts... but after the telnet command there is nothing I am assuming there is an issue redirecting telnet info and the telnet session terminates the second I try to read the data

View 3 RepliesI have a Data Repeater in a Windows Form, within the data repeater I have a label and either a radio button or combo box, the amount of radio buttons and the text for them is brought in from my database as is the label and combo box.
The label is a question and the radio buttons or combo box allows the user to answer the question.
What I want to do is get the checked status of the radio buttons so I can then reveal the next question if it is needed. e.g. only show question 2 if question 1 is answered No.

I'm trying to create a program that will disconnect/connect you from the internet.Example:When I press F10, I get disconnected from the internet. When I press F11 It connects me to the internet.
View 4 RepliesFirst of all let me say that while I was knowledgeable enough to create my program using VB-10 express I am by no means fluent in 'programming' speak .. so if you choose to help me please don't use technical jargon.. just explain as if you are talking to a 6 year old ..
Anyways I would like to give my program to some friends either by Email or via the internet (I have a website [url] (it is a wordpress blog) but I have no clue as to how I would get it onto my site.
I have attempted to Email the files .. first I had to change the file extension because Email would not send an .EXE file.. Then I tried to ZIP the files and send them via WINZIP but my recipients kept getting 'unable to open file' messages.
How can I make it so when you press a button, it opens a webpage?
Also, if I wanted to have a website for helps or hints, where could I put it? Like, a site for others to read info on my game which I could make, say.
I am making a program that gets files and folders off the internet.I want to make a window simular to a windows explorer window only these would get the files online.My problem is href tags for each one of the nodes and then get the files into the listview control.

View 21 Replies had 3 courses in computer science 10 years ago and decided to go into economics. After a 6 year and continuing career in economics, I decided to dabble in code to assist my economic career. In this pursuit, I have developed some neat things, but I have a simple problem. I code an application, hit build, hit publish, receive a setup and manifest, then put it on my usb drive. Plug the usb drive into another computer. Drag the setup and manifest to the hard drive, hit the button, a graphic regarding Launching Application comes up, then immediately a window comes up stating:
Cannot Start Application.Cannot download the application. The application is missing required files. Contact application vendor for assistance.
The errors stem from the manifest file. It says downloading the file (file path) Hello.exe.manifest did not succeed. It then follows with 3 lines of filepaths for the Hello.exe.manifest.
I am running VB 2010 express. I made a slot machine game for my mother for her birthday one Computer A. I moved the published files to Computer B as described above to test before giving to my mother. The game isn't too important at this point because I tried to test whether the game itself was the problem or if it was my error in lack of knowledge of how to deploy. As such, I created a program called Hello. In Hello, there is simply a form1 and a button1. When clicked, button1 displays a messagebox with some text. Not a rocket science program.
My intention is simply this:Allow the Hello program to be put on another computer via a USB drive and then installed.The two computers are not networked and let's assume the second computer cannot connect to the internet. When I go to the wizard, I select the location I want to publish to. In this situation, my desktop.Next, I select CD-ROM/DVD-ROM instead of UNC path or website. I don't know what UNC path is. I presume CD-ROM/DVD-ROM would be similar to USB drive in that it is a removal data storage item.I chose that the application will NOT check for updates.Finally, I receive this:The application will be published to:
file:///C:/Users/ComputerA/Desktop/
Where I find the files, put them on the USB drive and try to install on Computer B.Also, for more information, I can use those files on the originating computer and they do SUCCESSFULLY install and I can use the application. I have not figured out why it will not install on another computer.
