The field is too small to accept the amount of data you attempted to add. Try inserting or pasting less data.

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.

I'm still playing with my program that has multiple RichTextBoxes. What I want to do is to be able to save the data in all these boxes (only about 10 characters max in each box) to a simple text file and then reload the saved data into the exact boxes they came from at a later date.

<VB.Net 2010 + SQL Server 2008 + Linq To Sql>
Let's say I have ten rows on a data grid and I have changed data of three rows.
I am trying to save data by Linq for those three rows, but I am not sure how it is possible to save them.
I can do it by looping whole rows by checking each row for any change.
Is there any smarter way rather than looping by code, such as For Next.

how do you save data stored in an array of records (structure) to a text file using StreamWriter? I currently have
Private Sub btnSaveToFile_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSaveToFile.Click
Dim sw As New StreamWriter(New FileStream("EmployeeDetails.txt", FileMode.Create, FileAccess.Write))
For Each record As EmployeeType In employees
[code]....
but it doesn't work. My array is fixed and currently has 3 elements (for testing purposes). If I enter two records and add these to the structure I get the following data saved to the text file:
123,helen,66000
879,john,89975
0,,0
How do I stop unused elements of the array being included when writing to file? Should I use a dynamic array instead and if yes, how do you use dynamic arrays with structures?

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

how to display data coming from different tables in access in a form?...the case is this:
3 tables in access:
AddBook(tablename) - ISBN(primary key), Book_Title, Author
Student(tablename) - Student_ID(primary key), Student_Name, Course, Year
Transact(tablename) - Transaction_No(primary key), ISBN(foreign key), Student_ID(foreign), Date_Borrowed
i think you can already picture it out... so what i want is to display data from Transact table and also display the data from Student and AddBook table base on the value of the foreign keys in Transact table....

I'm currently attempting to save data inputed into a data grid clicking the "save" button. My problem is, I also have another DB opened in the same window that also needs to be saved. The second database is pulled up by the contents of a text box, so there for it has no real Dataset to call on. It looks something like this.
[Code]...
I try to run the update command it always throws the exception "Cannot find table 0" or "Update unable to find TableMapping['Table'] or DataTable 'Table'." I tried declaring the connection the same way as the code above and then simply calling the da.update(ds) but it wouldn't do anything.

Im currently making a program. It loads data from database fields into an combo box. Everything works so far, It just seems to be a mess. Do i need to have all the datasets and data adapters? or can i get away with just using 1 of each. It seems like im doing it wrong, and although it works it seems like a difficult and messy way of doing it.
Also i would like to assign the firshermenID to a variable depending on the fisherman name that is selected in the combo box. When button is pressed: id = fishermanID of the current fisherman (cmbFisherman.text)
