Establish A Connection When The App Is Launched And Keep The Connection Open Until The App Is Closed?

May 20, 2010

I'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.

Sql Connection Error - Re-establish Connection To The Server

May 14, 2010

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?

Can't Seem To Establish A Connection Between My Two P2P Applications Over The Internet

Sep 14, 2010

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:

System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it 255.255.255.255:8787

Way To Establish A Connection For Use With An ADO.NET Command Object?

Sep 11, 2009

I'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?

Establish A Connection To MySQL Via VB & Display Simple Query Results On A Form?

Dec 12, 2010

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?

EDIT
Using MySQL 5.1

VS 2010 : Establish An OLEDB Connection And Return The Values From The Selected Table To A DataGridView?

Apr 16, 2010

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.

A Program That Uses Constants To Establish The Base Pay, The Quota, And The Commission Rate?

May 6, 2009

I need to write a program that uses constants to establish the base pay, the quota, and the commission rate. The Pay menu item calculates and displays the commission and the total pay for that person. However, if there is no commission, do not display the commission amount (do not display a zero-commission amount).

Write a function procedure to calculate the commission. The function must compare sales to the quota. when the sales are equal to or greater than the quota, calculate the commission by multiplying sales by the commission rate. Format the dollar amounts to two decimal places; do not display a dollar sign.

The summary menu item displays a message box that holds total sales, total commission, and total pay for all salesperson. Display the number with two decimal places and dollar signs.
the Clear menu item clears the name, sales, and pay for the current employee and then resets the focus.

The Color and Font menu items should change the color and font of the information displayed in the total pay text box. Use a message box to display the program name and your name as programmer for the about option on the Help menu.
[code...]

So the issue is when I push calculate and summary, the total sales comes up, but not the total commission or total pay. Also, the color only changes to blue and that is it. I am not sure how to get the color or the font menu choices to be able to be choosen by the user. Is that possibile?

Create A Connection To A Database?

Aug 5, 2009

I wrote a small application in witch I create a connection to a database. I'm new to this, so I followed the steps in MSDN help. I first created a link to the database with the "Datasource" of the Visual Studio environement. Then, in the code, I create instances of the dataset in the datasource and use a tableAdapter to register my changes in the database.

Now I want to allow the user of the application to specify the path of the DB file he wants to use. How can I do so? Do I still can use the datasource in the VS environment? I don't know where to start.
