VS 2010 Save DataTable To Access DataBase?
Dec 27, 2011
I have a DataTable (comprising of three columns) created at runtime & populated by the users selections in other parts of the app. The DataTable is required as I need to manipulate the users data before graphing it, etc.I now need to save the DataTable (& associated data) to an Access DataBase so that I have a record of what the users data was.
Everything works fine apart from the saving of the DataTable bit........
I've managed to get the following working :-
For Each row As DataRow In ResponseTable.Rows

I have an application that users will save a list of clients to a database. The extension on the database is .sdk, and I think is some kind of sql database. The user can save rows and add rows to maintain a client list, but when I release an update, I have to install it without the database file. If I install with the database file, then their current client database is replaced with a new blank database.
my issue is that I need to add columns to tables in their existing database without overwriting their current rows. For example, i have columns for client name, address, and phone number currently. On my next update, I want the user to be able to save client birthdays. Here is what I have:

I have a VB 2010 program with a single-table Access Database.I have selected the option to copy the Access Database to the output directory.When doing so, the program copies the original database to the inDebug folder.I want the original (NOT the copy) to be modified when the program is being tested.Also, when I attempted to publish the program and run it to test, I got an error which was sourced to be a temporary file (which was the database) that was missing.I think this is a reaction from the "Copy Always" option.

[code] info: using access 2003 (.mdb) the Date of Birth field has been set into Date/Time.

I have picturebox that the user can import an image, and then save it to the datatable. I can save it with no problem, and the image, which is a logo, will populate onto my crystal reports pages.My issue, is that I want the logo to automatically load into the picturebox when the user opens my settings form. How can I do the opposite of the following:
'set the company datatable for sub
Dim borrowersrow As PlannerFilesDataSet.CompanytableRow
'use only the first row

I want to save a datatable to the app.config file (My.Settings) and what i have understand is that you can use the Datatable.WriteXML to convert it to XML and then save that string to the settings.
But how do i rebuild it from the xml? Do i have to create my own code to do that or is there a method?

I need to write a method in C# to save all rows in a given datatable back to the database, but I cannot depend on the rowstate of each row. I can't think of how best to do this without extensive looping through the database table data or constant database querying.
I want to essentially perform the following insert / update for each row in the datatable, but more efficiently:

I've been perusing some hep forums and some help books but cant seem to get my head wrapped around this. My task is to read data from two text files and then load that data into an existing MS Access 2007 database. So here is what i'm trying to do:
Read data from first text file and for every line of data add data to a DataTable using CarID as my unique field. Read data from second text file and look for existing CarID in DataTable if exists update that row. If it doesnt exist add a new row. once im done push the contents of the DataTable to the database.
What i have so far:
Dim sSQL As String = "SELECT * FROM tblCars"
Dim da As New OleDb.OleDbDataAdapter(sSQL, conn)
Dim ds As New DataSet
[Code].....
In constructing my table i use "SELECT * FROM tblCars" but what if that table has millions of records already. Is that not a waste of resources? Should i be trying something different if i want to update with new records?
Once Im done with the first text file i then go to my next text file. Whats the best approach here: To First look for an existing record based on CarNum or to create a second table and then merge the two at the end?
Finally when the DataTable is done being populated and im pushing it to the database i want to make sure that if records already exist with three primary fields (DriveDate, DCode, and CarNum) that they get updated with new fields and if it doesn't exist then those records get appended. Is that possible with my process?

I've been browsing these forums for a day looking for the answer to this, so far nthing has fitted.I've got an access 2000-2003 database containing a whole pile of data for a VB coded application to use. One of the tables in the database needs to be able to be updated with data from the application.The new data is stored in the app as a datatable. I need to replace the original table in the Access file with the datatable in the App.
I'm changing as many as 60 values at a time, so defining these as parameters in an OleDbCommand would be impractical and frankly ridiculous.

Source: DataTable
Destination: Access Database Table
I should mention that the DataTable contains data resulted by an SQL SELECT query and it's not related to the "targeted" Access Database Table.

I am trying to import data from an access database to a access database that my project uses I am having problems with combo box fields in the database with the data. I want to import what is displayed instead of the numerical key value. Example: The combo box displays employee names but the value stored is the key value from the employee table so instead of importing John Doe it imports 2 is there a way to make the actual name instead of the number?
