View 4 RepliesVS 2008 : DockManager - How To 'listen' To Form MDI Children
Jul 13, 2009I'm trying to create a MDI DockManager component. Basically what it should do is take each MDI child form and turn it into a TabPage. Instead of showing the MDI forms, the main form then hosts a TabControl with each 'form' as a TabPage.I expect this to be quite a big challenge, and I know I will probably not manage to do it... But it would be a great control if I could!Well, for this to work I need my component to know when an MDI child form is added / removed. As far as I know, there are no events the form throws when this happens... The forms are not added to the Controls collection (are they?!) but the user merely sets the MdiParent property of the child forms.
The only useful event I could find was the MdiChildActivate event, which should fire when an MDI child is activated. I am pretty sure that is not enough for my idea. It might be enough to detect new MDI child forms being added, but if one is closed (eg, removed) there is no way I can detect that.So, I'm basically looking for a way to detect when an MDI child is added or removed from a form. Is that possible at all?

Close Connection To Access Database?
Dec 23, 2009I 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.

View 4 RepliesClose Oracle Connection In Program?
Aug 13, 2011In 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, 2011SQL 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?

View 1 RepliesSql Server - Long Pause Trying To Close ADO.NET Connection Object
Oct 14, 2011I 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?

View 1 RepliesVS 2008 Log Off - Shutdown - And Restart
Dec 24, 2009I'm trying to create a way for the User of my application to Log Off, Shutdown, or Restart the PC.
The idea is that User can more quickly access these options from my application and if they choose, force these actions instead of waiting for the OS to respond.
Here's how I'm trying to do it:
CODE:
Log Off works just fine. It's shutdown and restart that doesn't work. From the research that I've done, the Consts seem fine and the function obviously works correctly because Log Off works. I am running the application as an administrator, so that should affect it.
