Testing Server Connectivity - Verify Connectivity From Application To Various Servers?
Feb 28, 2009
I 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

I am using Visual Studio 2010. I want to do database connectivity using VB.Net and MS SQL Server 2005. I know 1 way of doing this. Following are the steps...
1. Create a new Data Source Using Data Sources Window.
2. Select the appropriate view like details view/ data grid view for that data source
3. Drag that data source on your form and connectivity is done. Also all the controls are created by the visual studio.
This feature is really cool but I want to learn database connectivity by pure coding without using such advanced features. Also is it possible to do connectivity from a class library ?

I 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:
Private Sub Window_Loaded(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles MyBase.Loaded
If NetworkInformation.NetworkInterface.GetIsNetworkAvailable Then
Dim bi1 As New BitmapImage
[code]....
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.

I making a software in VB 2008 that connects to a SQL database. I have setup the connection on my machine but the problem is that this software is a project for university and i have to present it on a laptop, so is there a way for me to move the software to the laptop and connect it to the database on the laptop, which already has SQL installed, without changing a lot of code, because right now every time i move to program to the laptop i end up changing the connection code for every Form. I know this is a bit off the topic, but is there also a way to move my SQL database files to the laptop or do I have to create the same database on the laptop again.

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.

I am using the following code to establish a database connection to my datagridview and Access database. Here I am giving my file path name to the connection. This code works fine only on my computer. To make this code run on another computer I need to change the database pathname in the code. Is there anyway I can make this connection dynamic so that I can make this program run on any computer

give me the source code to add database connectivity in VB2010 express through ADO.Net. Including all the commands to add, update, delete, retrieve and modify the database fields. It would be really helpful if anyone can provide me with a small prototype working model with the source code.

"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

I 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.

How do I check the connectivity to Remote Desktop through Visual Basic (if possible). I would like to run a program checking if servers is up running normally. In some cases servers will respond to ping, without being able to connect to RDP. It would be great to a program being able to detect loss of RDP-connectivity almost as soon as any problems appear.
