Table In Access2007 DB Gets Overwritten When Updated?
Nov 6, 2011I'm trying to access 2 tables within the same DB in Access 2007, but I have a problem when saving information to one of the tables, I can do it with one table but when I try to save the information to the second table the data gets overwritten, not sure why, because I use the same procedure for both of them, just changing the variables to avoid mixed data, this is the code that I use to connect with the DB and fill the DataSet:
Try
dbProvider = "PROVIDER=Microsoft.ACE.OLEDB.12.0;"
dbSource = "Data Source=.\Almacen.accdb;Jet OleDB:Database Password=Slackware"
[code].....
Again, it works fine when saving info to one table, but using the exact same procedure (with different variables) saves the new data but overwrites the previous information
Parameter Update Reports 1 Row Updated But No Data In Table Added
Oct 13, 2011I am getting an incorrect repsonse after an update to a table. In my RowUpdating event I have the following code which builds an Update Parameter to call an SP to update a table. I must be doing something wrong but everything runs fine. My rowsAffected variable reports 1 after the update, but the table never gets the data.[code]I found a solution that is working. On the original DataSource for the update command I needed to add the following.[code]This in essence allows the original data source to call the SP. Note: that the command type needs to stay as TEXT not Stored Procedure as one might think.
View 3 RepliesUpdated Table Loses Saved Data After Project Rebuild
Mar 17, 2009since I still use VB6 and the code is in VB8, I can't find the solution.The sub below is executed in a button's click event, and is supposed to save data to his database. It seems to work fine : you can add persons (in a separate form), and see them appear in the datagrid. You can stop the program, go back to the VB editor, and run it again (without rebuild), and the previously added persons will still be visible in the datagrid. But...If you add some persons, then go to the editor and force a rebuild (for example by adding more code), and than run the code again, the the previously added persons are gone (nomore visible in datagrid)!To me, it seems that the problem is to effectively update the database. I have searched on the internet about this topic, and I read that you must "set" the UpdateCommand.

DB/Reporting :: Updating Client Data Tables When Data Table On Shared Drive Is Updated?
Sep 28, 2009I would like to know the best, or standard, way to accomplish real-time client updates in a small multi-user application using an access data table as a data source.Specifically, this application will be used by 3-4 people. It uses a datatable which is filled on form load and bound to a datagrid at design time. The datatable is stored on a shared drive. The data table on the shared drive is updated in two ways:
1) Users can update the datagrid which then updates the datatable on the shared drive via the data adapter's Update method.
2) A server application does some work on some text files, periodically updating the data table.
I need the clients to reflect the changes to the data table on the shared drive as closely to real-time as possible. I know that the data table stored in memory on the client is disconnected from the data table on the shared drive, so I must query again to get the updates.
1) Is there an alternvative model I can use which is connected, and which will automatically reflect the updates in the data table on the shared drive?
2) If not, what is the best way to check for changes in the data table (so I can know when to call the data adapter fill method)? I am planning to poll the drive for a change to the .mdb file, raise an event and then fill the data adapter when the event is triggered. I am using this method successfully now to check for changes to a text file in another application, and I know how to implement it?

View 8 RepliesAccess Database Is Not Updated?
Dec 2, 2009I'm trying to write my first application which connects to an Access db. It took me hours to understand this, but I figured out that, if during the creation of the connection I chose to copy the mdb file in my project directory (VB asks this), I get that the database is not updated. Everything works, except the save button which saves new rows in the db. If I answer no, and the original mdb file is used, the database is correctly updated as expected. Is there a reason for this? Why is this happening? Shouldn't the database bu updated anyway?

Count New Or Updated Records?
Sep 10, 2010I am using a table adapter and the update code as below in a Try/Catch block as shown on the MSDN site.
Me.MyTableAdapter.Update(Me.MyDataSet.MyTable)
This all works fine but I should like to return to the user a MsgBox which displays the count of new records added and/or existing records amended.I know I could count the records in the underlying table before and after the update, the difference being the count of new records. How can I count amended existing records ?
Email When A Form Is Updated?
Jul 7, 2009I am using the project management database created by Microsoft to track our projects. I would like it to notify (send an email) out to people once they are added to a project. And then send another one out when their due date is a couple days out as a reminder. Can someone help me with this. I am not a guru at programming and am just starting to get in to it. I would love to get this task done and then I think this database is complete. ( I am guessing I need to use the DoCmd.SendObject, but from there I am lost and what needs to go before it.)

Jun 17, 2009I have some text boxes in my form that takes data and saves the data to the database. There is a combo box on the form that loads data from a specific field of a database.
When I enter and save the new data (using the textboxes), the combobox doesn't show the newly entered data. I tried to refresh the combobox using code like combobox.refresh, me.refresh etc....to refresh the form but nothing is working.
The combobox only display the new data when I close the form and reload the form again. Anyway, the data loading in the combobox is done using datasource, displaymember, valuemember in the properties So, how can I make the combobox show the updated record (field)?
the combobox name is cboManager
the Displaymember: Mname
