This will happen at random, and I can always just catch the error and re-establish connection to the server, but I am confused as to why. When doing lots of inserting into the sql server, I only establish one connection that is public, instead of many little connections. I had my doubts on a public sql connection, but it's been running great, and I've seen no problems until this morning. Again, this random moment I hit an error that stated, sql connection state is broken. Is it bad practice to just accept this error, and when it happens, re-establish the connection?

My project List:
1) My idea is establish a connection between PC and Mobile through IP address in first, but my question is 'How to do it' ? izit same like PC to PC by using Winsock open a port to access? i'm using VB.Net 2005 for PC and Net60 for mobile.
2)My mobile phone Nokia 6220 Symbian OS is support GPRS/3G. Since the GPRS/3G can connect to the internet, izit means mobile itself have a IP address and service provider in order to surf the web? So, can i connect my mobile phone to PC through this gateway?

I am trying to connect a VB.NET 2003 Oledbdataadapter through the wizard to a SQL Server 2005 Database, but i get an error message during the wizard.These are my steps:New Connection, Select provider (Microsoft OLE DB Provider for SQL Server), Select Connection:server name, log on: use windows NT integrated security, select database.

View 3 RepliesI'm developing a device app in VB.net that will access a SQL Server database. I need to establish a connection when the app is launched, and keep the connection open until the app is closed. I've done the following:In the Master Module:
Public CNN
As SqlConnection
In the Main menu form load:
CNN =
New SqlConnection(sqlConnString)
CNN.Open()
Then when I want to read from the database:
Dim sqlDR
As SqlDataReader
SQL = "SELECT Name FROM Table"
[code]....
When I run the same code without the global CNN, but rather dim the connection inside the Select function, all works well.

I just can't seem to establish a connection between my two P2P applications over the internet(LAN works perfectly fine).
I have tried the following.
- Disabling Firewall
- Changing Port
The only way I can establish a connection is if I'm connecting to the same computer using the universal IP or the local. Does anyone have a fix for this? Oh and here is the error that I receive when trying to connect over the internet:

View 1 RepliesI'm designing a web service in ASP.NET and VS2008, and am using typed datasets for retrieving table data. These work well and establish their own connections through their associated TableAdapter objects. Edit: I'm using VB, BTW!I am now attempting to run a custom SQL string using a DataAdapter and a Command object, however I need to reference a Connection object in order for the Command to work. What is the best way to handle this?hould I:a) Create a global connection object using Global.asax, retrieving the connection string from web.config? (I've been trying that one already, with not much success)b) Create a class-level connection object using the InitialiseComponent method, also retrieving the ConnectionString from web.config?c) Retrieve a Connection from one of the TableAdapters that I've already created in my typed DataSets?d) Something else I haven't thought of yet?

I have a project in Visual Studio 2008 and there is a working data connection to a MySQL database. In other words, I can query the db directly from Visual Studio and it will display the results.
I've tried a couple of approaches that I found online for writing a connection string and accessing the db, but no luck yet.
All I'm trying to do is code a button to query the db and then reset the text property of a label/textbox to display the results based upon another label/textbox value.
The pseudo-code I am imagining is something like this:
Private Sub query_submit_button_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles query_submit_button.Click
result_textbox.Text = SELECT field FROM table WHERE otherfield = key_textbox.Text
End Sub
I didn't see any related questions posted on SO - forgive me if I missed one that already exists and this is a dupe.
What is the correct way to accomplish this?

I am unable to load the dat into the data Grid. Here is where I keep getting stuck.
dgvOleDb1 = table.Select
dgvOleDb1.DataSource = DataGridViewEditMode.EditProgrammatically
dgvOleDb1.DataSource = ds.Tables(0)
I am confused; I am using VB2010, IBM.iSeries.DB2 on an as400 V5R4. I am trying to establish an OLEDB connection, and return the values from the selected table to a DataGridView. I had one of the admin's make me file named GARBAGE, in the Rprtaccess catalog. In the past, I have been able to connect via access and an ODBC connection. My project is too big for access, and the SQL middleware we have is clunky and not user friendly. This is a program that will generate the SQL statements, specifically the WHERE: clause and populate the datagrid with the selected criteria. In essence I am making a user friendly striped down program, that has variables that are manipulated by the end user, and the rest, referenced tables and libraries are coded.
