Close Connection To Access Database?

Dec 23, 2009

I created a connection to a Microsoft Access database by using the wizard. Now in the server connections I see my data connection to the db. I'm trying to create a method to compact the database, so I used JRO to do it. To do it however, an exclusive access is required, and when I try to call the method I get an exception.

Close Oracle Connection In Program?

Aug 13, 2011

In my program I got multiple spots where I open a Connection to an Oracle database, read some lines via a stored procedure which returns me a cursor, put them in an IDataReader, close the connection and go on.

Now everything works fine till the point of closing the connection. I've watched the connections opened to the database via TOAD for Oracle and I figured out, that the database seems to keep an connection opened after I said m_Connection.Close and m_Connection.Dispose.

I use Oracle.DataAccess and get an error after a short time, that there are to many connections. I debuged my session and made sure, that vb performs the close() command and it does it, but the database not.

DB/Reporting :: SQL Connection Open/close?

Dec 16, 2011

SQL connections confuse me sometimes In almost every SQL related code on the internet the routine is like this;

* Open connection
* Execute SQL command
* Close connection

Is it good practice to just open a connection when the application starts and use that connection until the application closes?I know that sequential connections are required when processing more queries, but what if I need to poll a certain Table every x seconds? Isn't is better to keep that single connection open for as long as the application is running (and re-open when a failure occurs) instead of opening a new connection every x seconds?

Sql Server - Long Pause Trying To Close ADO.NET Connection Object

Oct 14, 2011

I am performing a simple exercise of opening an SQL Server database connection, pulling the first record of a table from a DataReader object, and then closing the object. However, I have noticed that theres bit of a delay, about 5 seconds or so, in closing the connection. However, the delay only occurs after the command object executes the specified query. I've worked in a setup like this before and don't remember there being such a long delay while closing the connection. [Code] The connection closes almost immediately. What gives? I have narrowed it down to the where the .ExecuteReader line that causes the delay in the connection close. Whats causing the delay and how do I resolve it?

I only mapped the drive onto their computer and then I cope the shortcut to the application. can I close all the application that is running with a single code? I sometime need to close all the application first before I can do anything with the application (for example, modifying the report etc.). My current method is still the manual one, which is calling everyone to close their application or running all over the place closing the application myself.

RTF Close - Add A Close Button To Menu Strip That Will Just Close The Currently Opened File

Jan 16, 2009

I'm currently in the process of building a text editor type program, and have run into a brick wall. I haven't done VB in years, so I may just need a little reminder on some things. I have coded everything so far as far as opening files, saving them, changing fonts, colors, etc. However, I'm looking to add a Close button to my menu strip that will just close the currently opened file, and not the entire program, while also ask the user if he/she would like to save before closing the file, and then if they select yes, it will show the save dialog, and if not, it will go ahead and close the currently opened item.

Close() Puts Forms Into Crazy Open/Close Loop?

Mar 4, 2011

In a program I'm working on, I want a "Loading..." dialog to close when it can't log in to a site using the username and password provided by the user. Basically, I have the code set up right because the function it is supposed to carry out when that occurs does work, but for some reason it ends up in some really weird stuff happening. In the Loading form, I have it set to do "Form1.Show()" and then "Me.Close()", assuming it would simply show the login form and then close the Loading form. However, when this happens, the Loading form closes, and then for only an instant Form1 shows, and then the Loading form shows and Form1 closes. This happens forever until I stop the debugging, and I can't seem to figure out why. Am I using the wrong method? What exactly does Me.Close() do anyways? All I want to do is close the form and open another

Forms :: When Me.close() Doesn't Close Form

Mar 2, 2009

I have a situation where me.close() doesn't close the form. I have a form with a button with the code seen below. What happens when the button is clicked is the new form shows, but the original form(calling form) is still there. When I go into debug mode, I can see the me.close() execute, but nothing happens (calling form stays open). When I close the second form both forms close. If I comment out the call for the second form to open the first form closes without problem.
