This program is very difficult for me, but I must get threw it or I cannot finish... What I am doing is making a Database of foreign Languages with the spelling of the words and the pronounciation inside the database... The USER enters a paragraph of words into the translator textbox and pushed translate. The program has a DATABANK of words with the phonetic spellings and matches the word, then translates to phonetics. The problem is that new words keep appearing inside the language. So I incorporated a Database of 2 fields

I coded a program to access a Microsoft Access 2010 database. The program is written using Microsoft Visual Studio 2010. I get the error message that the database I'm trying to access is in an invalid format. look at the code below to see what I missed. The error is in the datasource statement.
I am attempting to use VB2008 Express to Display, Edit, and Append an Access database. I can display information fine, but for some reason updating the database is posing an issue. The code below runs fine and doesn't throw any exceptions.However the Access database itself does not update. When I physically open the table in Access, the field I am attempting to change remains empty. Furthermore, when I try to display the changed field in a label (the very last two lines) I get a discrepency between what is in the data set and my dbrow object despite filling the data set and setting the dbrow = data set. For some reason label30 displays the information that I want while label13 remains blank.
Try Con.Open() Adapter = New OleDbDataAdapter("Select * from Machines", Con) Builder = New OleDbCommandBuilder(Adapter)

I am trying to update a field in a MS Access database and it appears to be working but it keeps coming up with an error on the last line "executeNonQuery", I think it has something to do with data type but not sure.

I've created a Point of Sale program using Access and VB.net. I have an Inventory table from which items are sold. There is a quantity column and I want to be able to reduce the quantity for any item by the quantity that was sold in the point of sale front end. For example, there are 5 bracelets in inventory and 1 is sold. The quantity is typed into a textbox. The inventory quantity should now be 4 in Access. I don't know how to make this happen from the point of sale screen.
I am building a VB table which syncs with Access using multiple forms. I have managed to complete the first form.

This is my code for update, but not working,UPDATE STATEMENT WRONG?
How can I do that? I already have the code I'm working on but it seems that it doesn't work really fine. I input an id number(unique) on a text box and click the search button. The entries that corresponds to the id number is then displayed on the other text boxes. And then I try to edit one of the entries manually(changing its letters or name) then I click the update button.
Here is now the problem: It really updates the entry but it makes a mirror of the entry with a different id number(maybe automatically generated). So basically the ms access database will now contain the old entry and the updated version of the entry.
I'm working a code to do an update statement but I get an error. I have the name of the column in a variable I added a parameters to pass the value but I get an error. The error says that Parameter @Ronda has no default value?
I am trying to make a little search system, so the user can enter a search parameter which then populate a DataAdapter, DataSet then DataGridView with the selected data then any change the user makes in the DGV are then commited to the MS Access (97) Database when a Update Button is pressed. This is what i have so far, at the minute it seems to populate the DA, DS and DGV but when i come to press the Update Button I get a pop up box with a long error message:
Private Sub btnSearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearch.Click connetionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source= " & frmMain.varDP_System
I have a program where a lot of the required information for it is stored in text files. I simply read this information into large arrays. However, I don't think it's necessary to load all the information each time. Rather, it would be more efficient if I could simply search through a list of items to find the one I need and then use the data from it, or to find a similar name and use it elsewhere.
Would I be right in using a database? And is database programming done in SQL? I have a book on it telling me to use the SQL Server (IIRC), so I shouldn't be doing it in the VB.NET Express GUI?
Here's an example of what I would do:
Hex = 03 00 => dex number 003 Search in file Pokemon Dex Numbers 003 returns Bulbasaur Check Bulbasaur base stats in the base stats file etc
So basically I'm reusing a lot of information. I think a database would be best and it would all be internal right? I'm getting complaints about access denied to a text file (since it's stored in the program directory in the program files).
So to cap up the few questions I have:
-Databases are done in SQL and not inside the GUI? -Databases would load internally? -I could search a database without having to load it into like an array or something?
