IDE :: VS Server Explorer Close Databases Connections While Debugging?
Jul 27, 2009
Every time I execute my application and the app try to access the database I received an error message telling me that the user cannot login into the database. This is because the VS Server Explorer have the connection opened. What I need is that every time I debug (F5) my app the Server Explorer close the connection with the database so I do not have to stop the execution and manually close the connection. Is this is possible? Is there any way I can setup the debug or the Server Explorer to do this?

I have a server which has around 300+ users on it. Though the problem is that its coded in VB6, and if somebody has a bad ping, everybody has a bad ping. I need a tunneling server which will tunnel the incoming and outgoing connections and make there ping appear to be 0 in the server. Client to Server, Server to Client.

I have an application running with a access db. I have written some code to copy & zip the db file to another location (selected by the user) for the purpose of backup. (I am using sharpzipwrapper)Whenever I try to run the code for the copying & zipping it gives me an exception saying that the file cannot be zipped as it is use.Do I have to close all open connections in order to backup the .accdb file? If yes then how? else what do i have to do inorder to get 'access' to the file.Do I have to exit the application to close all connections? These connections are written in code for e.g. :
dim
cnStudent as
oledbconnection

I am currently working on an asp.net web page with a GridView displaying a table from a database.This GridView has 4 DropDownLists that will be used to filter the data shown on the GridView. When the page loads 4 Sub routines are run, each one connecting to the database with a select statement to fill the DropDownList with relevant filter headings.
Initially, I had one connection with a loop that populated all of the drop downs but these contained duplicates. I then split the filling of each DDL so that the select statements could contain DISTINCT. I would like (and am sure there is a way here) to be able to populate all of the DDLs with data from one connection.
Code for one connection:
Protected Sub FillDepDDL()
Dim conn As New SqlConnection()
conn.ConnectionString =
[code]....
The other 3 column names: FirstName > DDLFN, LastName > DDLLN, Wage > DDLWag.This is only a test DB and the princibles learned here will be applied to a larger live project.

I'm pretty new to VB.NET and connecting to SQL Server.What is considered best practice when building an app that needs to connect frequently to a SQL Server DB to fetch, write, delete and update records?Should a connection be opened at app startup (a connection at start is opened to validate the user) and left open for subsequent transactions or should a connection be opened, closed and disposed of each time a read/write to the DB is required?

I have a .net window application created and I wanted to see if it's at all possible to place various file dependencies off the web server. e.g. is it possible to have the connection to the database be off a web server?
I also would like to see if it's possible to place one of the .dlls off the web and have code that points to it to load.

connect my vb.net application to a remote sql server database, so every one who installs the application would be able to connect to the same remote database. the application would obviously require the internet to run.i also want the option to add more databases in the future, preferably one for each business who would use my software.i am wondering the best way to set up this server that could hold multiple databases. i would think i have two options:
1) set up the server myself on a dedicated computer
2) pay for some type of service that host sql server dataases
so how would i go about executing these options? i dont know the first thing. which option is better?i do however know how to connect to a remote database so thats not what i am asking.

Right now, inside the access file, the mssql tables are set up as linked tables so queries can be written using tables from both databases. (e.g. "select * db1.table1 where db1.table1.somevalue not in db2.table1", or select into tables like that one)These queries need to be moved into a VB.NET project, but still be linked to the access file.ng loops or something?

I have been developing an async socket connection server and client program. I have been testing it, and noticed that if I connect to the server from my client and then disconnect. Upon reconnecting I am on a different port(local IP still). This is fine, however when I go to send a message, and the server trys to update all the clients, it eventually hits clients that do not exist anymore. I get the SocketException 10054, and upon connecting/disconnecting enough, it no longer works at all. My question is how do I clear out these no longer useful sockets from the server? I am doing currentsocket.Shutdown(SocketShutDown.Both); and then a currentsocket.Close(); after that. When a user disconnects.

I have an application which connects to a database, retrieves a username from a user's table and matches it against the username retrieved with System.Security.Principal.WindowsIdentity.GetCurrent.Name.On my localhost, everything works fine. The database exists on the development server but the application lies on my localhost. All of my authorization and authentication techniques are running smoothly.However, when I publish my application to the development server, I'm faced with the following error.Cannot open database requested in login 'databaseName'. Login fails.Login failed for user 'DevelopmentServerNameASPNET'.

Working in VWD 2010 Express I have an aspx.vb file with the following connection string:
Protected Function getPasswordLength() As Integer
Dim conn As New SqlConnection("Data Source=localhost;database=MyDB;Integrated Security=true")
Dim cmd As SqlCommand = conn.CreateCommand()
[code]....
This works when the code is on the web server / which is collocated with the SQLServer.However, when I want to debug, I have to copy to the server. I would like to be able to "debug in place" on my development machine and only copy files to the production machine periodically. Technically the production machine is not in production at the moment, but that's beside the point.Anyway, I followed the following instruction: [URL] I can now see the remote database, functions, etc. on the other machine (from the VWD running on the development machine). However, I thought I should then be able to execute this same code locally on the development machine using ctrl-F5, but I get the following error:
**Server Error in '/' Application.A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)**

I have a VB2008 application that uses SQL Server 2005 Exspress Edition. I was modifying my application and then decided to add a table to the mdf (named "Pipe.mdf"), which I have don many times before, but I must have messed something up when I made other changes. After I added the new table I opened the Dada Source Configuration Wizard to add the new table to the dataset and I don't see the new table to select it. However, it added a copy of "Pipe.mdf" and named it "Pipe.mdf1" to the Server Explorer.
If I delete this copy of the mdf, it appears again in the Server Explorer when I open the Data Source Configuratuion Wizard.
If I add a Table to the copy of the mdf ("Pipe.mdf1"), it shows up in Dada Source Configuration Wizard.
what to change so that the new table appears in the Data Source Configuration Wizard for the original mdf (Pipe.mdf) and not add the copy of the mdf?
