SQL - Make Application To Detect Itself The Name Of Server Present In Computer And Use It In Connection String
Oct 1, 2010
Ok I have a question about connection string in vb.net. Im using the string [Code] but here I am specifying the serverName by its name, now if I deploy my application and send it to another person to use it I see that server name is changing according to the name of the computer. Is there any way where by I can make my application to detect itself the Name of the server present in that computer and use it in connection string?

I have a problem when trying to detect the computers network connection status.
Here is the code I have used:
Dim IsAvalible As String = My.Computer.Network.IsAvailable
If IsAvalible = True Then Label1.Text = "Connected" Else <code>
<code>If IsAvalible = False Then</code> I <code>
Label1.Text = "Disconnected"</code></code>
End If [/ICODE] End If[/ICODE]
But for some even when the network is disconnected or the computers wifi is turned on I still get the result of "Connected". I think there something wrong with the code.

We are going to change the connection string in Settings.vb so we don't need to worry about what it is when our app runs on a different computer other than the development computer.

I have a little problem with application setting in VB.net 2008. I want to switch main server and backup server connection string with combobox. [Code] It did change the Application Setting connection string in the main form when combobox1 was changed. But the problem comes, when child form was called. On the child form there is DataGridView with Dataset using application connection string. Even the Backupserver was selected on the main form, child form dataset connection string doesn't change. I don't know how to pass the current connection string to child form dataset although it is set to use application setting.

I have a WinForm program developed in VB.Net with Visual Studio 2005. The program needs Microsoft Office Runtime installed atleast on the computer to allow the application to run without any errors.
Is their a way to check the computer to see if the minimum of the Runtime or Microsoft Office is installed on the computer? If either isn't I would like to display a message to the user on the startup of the application that states to atleast go to Microsot's site (I have full link to Runtime Download) and download the runtime for free.
Or is their a way to include the runtime as a component with my install for the application so if it isn't installed on the computer already it will install when the application is installed?

I've started building a small game where you move around a PictureBox control with keystrokes using the arrow keys. Everything was working fine....until I added a button.
Now the button steals the focus so that every time I hit an arrow key hoping to move my image, it just selects the button.
Is there any way to make the button selectable only by mouse click?

I use the media player tool in my program and just found out that some people get a serious exception on the loading of the program if they choose not to enable media player. How can I make it so that if they don't have media player enabled that the program won't crash?
I don't know where the designer puts the info to load certain controls, nor do I know how to make the program skip loading a control if it doesn't work.

I am planning on creating a service that measures the bootup time for a computer. It would go something like this:
1. Service starts and waits for CTRL+ALT+DEL screen
2. Timer starts when logon screen appears
3. User logs in and timer stops
4. Service waits for process X to start
5. Process X starts and service gets System.Environment.TickCount
6. Service subtracts step 3 ticks from tickcount
The reason for the logon screen timer is I don't want to measure if the user booted up and went for coffee or something and shows up 20 mins later to log in. Is there any way for the service to detect when the logon screen is present and when it's gone?

I have installed sql server 2005 in my machine which is installed vb.net 2008. I want my machine to distribute the database to the clients and make it as server.I don't have that much knowledge of how to overcome this issue as i am awfully naive about it.Let me start it here:I have got an application in vb.net...at first i was using ms access database 2007. then decided to switch on to the sql server since i want to distribute the database to the clients who are going to use my application.When i installed the sql server, i imported my access db files onto sql server database. i enabled tcp/ip as enable in the sql server network Configuration. i want use sql server windows authentication as my default user account of my system for the sake to simplify the issue.
Hence, i connected the sql server into the vb.net through the "add new data source".am done with that...the problem is how do i assign the connection string to the vb.net? Or how do i include a connection string in vb.net which tells every other computer that the database data source is in my computer so that every computer can automatically check it in the network.Where exactly shall i put the connection string...as far as my knowledge is concerned for access database, you can easily identify your connection string in project /properties/settings...it goes here and you put your database in any where.And what is the best connection string do i need for sql server 2005..computers are running windows xp.

How do I make a regex that can detect a certain character string that is either all by its self in a line, or separated by white space.
If I have the line:
"ot"
Or the line
"sdf gdfg dv ewrsef fvdf ot sdfsd sdot"
I want to be able to detect the 'ot', except for the one that is 'sdot'

I have a desktop computer with a cable connection on the back that allows me to watch TV on the computer using Windows Media Center. I had the idea of writing a program that would access this feed and send it to another computer (laptop) via my network. That way I would be able to watch TV from anywhere that my network spans. I have no idea if this is possible or how I would even do it,
So I have three questions.
1: Is it possible?
2: How would I go about access the feed?
3: How would I send it over the network?
My original thought was doing it in Flash, but I'm not very good at Flash so I wanted to do it in VB.Net.

I created a DB using following code.
Dim conn As New SqlConnection("Server=.SQLExpress;Data Source=;Integrated Security=SSPI")
Dim cmd As New SqlCommand("", conn)
cmd.CommandText = "CREATE DATABASE MyDBTest22 ON ( FILENAME = 'D:dbTestATTTTTTT.mdf' ), ( FILENAME = 'D:dbTestATTTTTTT_log.ldf' ) FOR ATTACH"
[code]....
It ran without any error but when I opened SSMS, I could not see my file attached to the server. Also, I tried to make a connection, but it says file does not exist but when I tried to re-run the above code, it says File already exists.Something wrong with my way of doing it? I want to see it attached with the instance of my SQL Server Express 2005, using SSMS.

I have two databases, one on my local work computer and other on a server. Both have been created with Microsoft SQL Server 2008. I can access both of them with connection strings that contains names of the servers and some other information. However the names contain only the ip-number of the server. And I need the full name of the server and the instance created, separated with "" character. I can see them in my SQL management studio but I need to get them from VB-code.I created SqlConnection-class but it finds only the ip-addressed name. SqlSourceDataEnumerator won't do good because it finds all unnecessary server names that I don't need. How can I find the real name of the server that is specified in the connection string?
