Middle Of Developing A Prototype That Will Connect To The Database?
Mar 30, 2010
I'm in the middle of developing a prototype that will connect to the database. The problem I'm having is that I'm seeing more than one ways of retrieving data from the database either by adding databindings or just use a loop to loop through each rows to get a column or two.
I'll try to put this clearer because I'm not sure what I'm asking myself. I have no idea what approach to take. The purpose for the application is to retrieve as well as add, update, and delete data from that database. I wanted to display the retrieved data onto any controls like a textbox and such.
Right now, I'm confused to figure out what's the best way to program: by bindings or just retrievals. Any suggestions?

I am developing an access database that will be shared with multiple users.I don't want the users to access the database directly so I will have them enter new data on a data access page. The data access page is stored on a Microsoft Share Point web page, and the database is stored on a network drive.Here is my problem: When new data is entered on the web page I need it to trigger a WillChangeRecordset event; however, I have not been successful because the web page does not declare a new instance of a recordset object.At a minimum I need the new data to be processed before the web page appends the new data to the table.

i 'm develloping an application that uses a sql server database, in my computer where i'm programming i installed the sql server in the same language of the OS, in the tests of the application everything worked fine. Biut after migrating the db to the main server, the values went crazy.. After some research and tests, i saw that the language of the sql server was in english and that was the problem.
My language settings says that the decimal separator is "," and the agrupment digit it's ".", and the sql server works in the other way "." is the decimal separator and the "," it's the agrupment digit. In my code i was using the CDEC to pass the values to the DB, to solve this i removed the cdec and send the parameter as a string (So if i send 2,33 to DB with CDEC i get 233 if i send the 2,33 string i get 2.33). This works for now, but i don't know if in the future i'll have problems...

I am developing a chat application using online connection to a mysql databbase. But i am facing a problem. After 10 minutes, MySQL closes all the chat connections because of the 600 seconds timeout (has been set by the host service i am using). I don't understand why is that happening cause every piece of my code which needs data from the database opens and closes the connection (i mean that it dosn't maintain the connection after the query's execution). If i .close() and .dispose() the connection, it still appears in mysql at sleep mode (it terminates only if i exit the program).
Dim MySQLCon as New MySQLConnection
Dim MySQLCom as New MySQLCom
Dim counter as Short

Iam developing a Windows application using Visual Basic 2008 with a SQL Server database. Throughout the program I give the user as many options as possible and have no problem with either the database or the windows forms. The program does not initially require a Login and I want toprovide the User with the opportunity to add a Login to the system. The default Login form is perfectly satisfactory.
The problem is that I can't figure out how to program the change sothat the Login from isopens the program rather then th form designated as the StartUp form. this forum I am able to prgrammatically change the form but I can't figure out how to make the requirement a permanent factor. I tried using a Constant, but if the User wants to change, you can't change the constant. Its an apparantly simple yes/no situation but if I set a varable to yes and then change it to no the next time the program runs, the change will be lost.

I am using VB code behind in Visual Studio 2008 to process data but can't figure out SQLConnection problems. I copied and pasted the connectionstring for my database from the explorer properties window but when I paste it inside the parenthesis of SqlConnection() it gives me an error. Also if I name a variable " dim myconnect As New SqlConnection" in does not give me all of the methods or attributes that are associated with it. Is this a Express Edition limitation or do I need to make some specific declarations to get it to work. this is what I have so far
Dim
connectString As String
Dim myconnect As New SqlConnection()
[code]....
myconnect. If I try to put open() at the end of this it says its not a member of SqlConnection. I have a dataset but no way to insert into the database

I am trying to connect to a database in VB 2008 express the book I am using is for an older model of VB. The book says to go to view and click on server explorer, and then a database wizard should open. VB 2008 express doesn't have a server explorer under the view section. I know what code I need to enter into to the two buttons I have I just do not know how to open the wizard.

Failed to generate a user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed...
someone gave me a link to changing the database connection using an instance. When I tried to type what the instance of my SQL server 2008 I must have put the wrong information into the database connection instance.
What is the database connection instance called for SQL server 2008?
