SQL Connection - Creating And Working With Database
Jan 7, 2010On my development PC I have SQL Server installed, and my SQL connetion works perfect. I use a trusted connection. But on other PCs, where the program should work later, there is only a SQL "Express" installed (by another application), and it seems they have an password on the SQL Server (I guess). I have no chance to get the password from the other application. My connection is not working here. I created some connection test, but it does not seem to work with the trusted connection. I need the SQL only for creating my own database and connecting to my own database. So how do I create a connection with SQL Express for creating and working with my own database?
Here my code for testing the connection so far (Fehler means Error, erfolgreich means Success) Private Sub mnu_Verbindung_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles mnu_Verbindung.Click
Dim bolFehler As Boolean = False
Dim sServer, sDatab As String

Check If An SQL Connection Is Still Valid?
Jun 4, 2011I have an VB.NET application. This Application is permanently resident in memory and minimized to the tray area because we use it very often. The problem comes in when we VPN into a client's site. These VPN connections trash all other network connections to and from our machines.Then every time my VB.NET application refreshes its database, errors start occurring, because the machine has lost connectivity to the SQL server, however, these are not at the connection level, but only when the reader attempts to read.
I am checking for connection.open, but because of the SQL connection pooling, I just get a previous connection that was valid before the network was cut. Is there anyway to check if an actual SQL connection is valid, prior to re-issuing a connection from the pool?[code]...

Check Internet / Network Connection ?
Nov 19, 2011This is the work of one responder for the most part, and is not indicative of the quality of most of the posts.But you can judge that for yourself.
If you are writing a program that is used to monitor the status of your network, then this thread may not be of interest.
If you are an application programmer that uses network resources to accomplish your goal, i.e. you are using SMTP, FTP, HTTP, NNTP, NTP etc., and you think that you need to check for a connection first, then read on.Follow up to this.Before getting all geeky let's take a little detour...
Five days a week I get up, eat breakfast, check my email, forums, etc., take a shower, get dressed, and then drive to school.Many of you probably have a similar routine.What is interesting about that is not what we do, but what we dont do,because of our expectations and experience.Here is what I dont do.
I dont stick my finger in the electrical socket to see if there is electricity for the coffee maker and toaster.I dont fire up the command prompt and ping some host on the internet to see if I have connectivity.I dont check the battery, tires, water level, clutch fluid level, washer fluid level, etc.,before I drive off.
All of that is based on expectation and experience.So why would you write an application that pings the internet before it did something (SMTP, FTP, HTTP, NNTP, NTP etc)???? Is your experience or expectation that the network will be down?To illustrate and hopefully convince you that, like Oblio, it is pointless, create a new form with three buttons. In the following examples I use a WebRequest / WebResponse as my 'Something'.Here is what some think is a good approach, the classic ping-then-do, what I think you shouldn't do.[code]....What is wrong with this code is that all of the network IO is being done without a Try / Catch block.

View 3 RepliesCheck What Application Block Connection?
Dec 3, 2009I'm having a problem with some users, my vb tools always check at the splash screen a response from a server with a simple:
Dim MyResult as string = oWebclient.DownloadString("www.mydomain.com/page.php")
This actually works for most users but in some clients the firewalls I think they block this call or bypass or something like that, I found that after telling the user to turn off the firewall everything works ok, now I have some users that according to them they don't have a firewall or they already disable and still they have the problem.
You can see from the image the error message they receive, so my question is do you know any kind of free tool that I can send to the user to maybe log what program or whatever is blocking the program to connect?
DB/Reporting :: Check If Sql Connection Is Good?
May 31, 2009I have a little problem with checking if a sql connection is good.
Attached here i have a simple vb.net program that should check if the sql connection to the sql server is good. If i just run it once it works very well. But if i use it in a timer and check the connection to the sql server every 10sec it will only tell me that the connection is good (V=0).
I have tested the code with turning of the sql server service.
Dim connect As String = "Server=192.168.1.2;Database=Test;User ID=sa;Password=12345;Trusted_Connection=False"
Dim sqlconnection As New System.Data.SqlClient.SqlConnection(connect)
