View 1 Repliesfor example i have this code :
Sub Month()
Dim Conn As New Data.OracleClient.OracleConnection
Conn.Open()
Try
Dim Cmd As New Data.OracleClient.OracleCommand
With Cmd
[Code]...
What will happen to the datareader when the Connection is closed ( Conn.close)
Will the Cursor that is used by the datareader be freed ? or will it stay open ?
If the cursor that is used by the datareader is still open , when will it be automatically closed ? or should i just closed it manually ?
Will it cause the dreaded "ORA-01000: maximum open cursors exceeded" ?

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.

I need advise on how to solve this scenario. I am not sure whether I should use any Report Application such as Crystal Report or I can just simply use datagridview.My scenario:In a new form, a table will show a least 3 columns.
First, ItemID
2nd, Total Quantity Sold for the Current Month
3rd, Total Quantity Sold: Last month
ItemID Current (Nov) October
ABA1 100 85
ABB1 80 90
Hence, I can compare the figure of the current month with the past few month.Right now, I do not have any problems building SQL_String for calculating the Total Qty Sold for the Current month and display it via DataGridView. But I am not sure how to additional column that calculate the Total for the past few month
I am trying to convert a VB6 Data Report (.dsr file) to a Crystal Report through the migration process within Visual Studio. I have read articles that reference adding a Data Report to a Project from Visual Studio 2005/2008 and that it will convert the Data Report to a Crystal Report, but I have not been successful in doing so. Does the VB6 Data Environment need to be converted too? Has anyone been able to do this successfully and if so, how?

I have a problem connecting to an access database. I'm currently trying to build a login/register program that reads the username and password from a database and allows login if the specified username and password are found. I have code that will work properly for that so that's not an issue. However, when I make an attempt to register a new username along with a bunch of other things such as email, password, etc. I am unable to because the database connection is closed. The code I'm currently using to open the database connection is :
[code]...
However, when I try to use this code to open the connection to the database, it leaves the connectionstate closed. I decided to then build in as a test, a block of code that would check on load to see if the connectionstate is open or closed. Each time I've run it so far by making a few changes it always tells me that the connectionstate is closed no matter what I do.
