I have a DataGridView setup on my form that connects to an Access database. When new data is entered in the DataGridView, the Access database is not automatically updated. I wrote some code that updates the access database by clicking a button. I'd like to attached that code every time I change rows on the DataGridView. Pressing a button every time to update is a hassle and sometime you forget. How do I do that?

View 6 RepliesThis may or may not need to be moved to the deployment folder...Okay I have a vb.Net application that connections to a sql server 2005 database "TacticalDB" while debugging the application I was using the connection string,
Dim con As SqlConnection = New SqlConnection("Data Source=.SQLEXPRESS; AttachDbFilename=" + Application.StartupPath + "DataTacticalDB.mdf; Database=TacticalDB; Trusted_Connection=True; User Instance=true")
Which works fine, but I have moved into getting the application ready for deployment and so I created a setup application in the same solution as the application. Now I have added the database file with the setup but when my application gets to the con.Open() line it catches an exception,
System.Data.SqlClient.SqlException: Database 'C:UsersJohnDocumentsVisual Studio 2008ProjectsBlackout_ScoutBlackout_Scoutinx86DebugDataTacticalDB.mdf' already exists. Choose a different database name.
Cannot attach the file 'C:Program Files (x86)MicrosoftSetup1DataTacticalDB.mdf' as database 'TacticalDB'.
[code]....
Now I only have the one place where the application should look for the Database and thats Application.startupPath/Data/TacticalDB.mdf and if im running the newly installed exe it shouldn't look back in the myprojects folder but it is.

I've been using trying to use visual basic to create a form which retrieves data from a Microsoft access database and filters the data to find the record starting with the letter retrieved from the user. When it is run without the query the data grid shows all the records. However when my original query is put in the application changes it and the value shown is null in all fields.

I am working on Visual Studio 2008. I have this problem with Windows XP. I have no problems debugging when the process starts but after a while it just disconnects then I need to attach to the process manually and after a longer while it again disconnects.I am seriously frustrated with this ,I had uninstalled the VS 2008 and re-installed my IIS and intalled the VS 2008 again but still the same problem.Initially VS will automatically attach, it will continue to do so on successive debug commands, but eventually after a while it stops attaching and it must be done manually. Hitting debug does everything, builds, starts the development server, opens the page and simply fails to attach.

I have a program that instantiates Excel, programatically updates it, and then closes it. In some cases, when I look in the task manager/processes, I can still see 1 or more copies of Excel running.
1) Is there a way I can, after creating an object reference to Excel, identify the PID or some other unique identification?
2) Using that, is there a way, after I think I have told Excel to go away, to see if the PID (or whatever) is still active?
3) Given that I have a PID, can I get a new object reference and try to tell it to go away nicely
4) If it still won't go away, can I force an end process of the task?
5) Is there a library or routine available that will return the active processes so I can search to see if there are any copies of Excel still running?
6) using the approach in 5, can I also find out if the item associated with the PID is running just as a process and not as an application?
