MS Access Database To Make Program Interactive But Cannot Get The Database To Update With The Entered Data
Apr 20, 2010
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 have an application in which I want to update only if new data is entered. If no data is entered, then it doesnot update.Any way I can check in the database? If it doesn't update, then it will not give a message that the records updated.
i am just developing a library management system as one of my project. i using vb.net 2010 and the MS Access 2007 as back end. when i save some records into my database through my application it is correctly saved and i confirmed it through opening the relevant table in the database. but when i restart the application all the entered data were missing.

I want to update data into an access database containing three fields of text type. so in the design i added three text box and one button.........on button click the data corresponding to textbox3 will be updated by textbox1 and textbox2. then i coded it as follows:
Imports System.Data Imports System.Data.OleDb Public Class Form1 Dim con As OleDbConnection
[Code].....
It is running and executing good........But finally the data in the database is not updated.........Hence i say the above code does not work......
Private Sub BooksBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BooksBindingNavigatorSaveItem.Click
I'm actually making a library system and I'm having problems with my data not saving in the database. It does appear in the DataGrid but after I close the application and check the database, nothing's there. [URL]

I got a system which i want to insert, delete, update the data into my database and the data from database will be display using datagrid. The below is the coding for one of my button, delete.
Private Sub btnDelete_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDelete.Click Try btnSearchEmpNo.Enabled = False[code].....

I can save my data to access database and in the access database field I set it to date/time.But problem is when I get the value out from the database.. the format is always month/day/year hour:minutes:seconds example today: 5/2/2011 12:00:00..How to get the value into listview becoming May/2/2011 without the hour..Here's my code to get it from database ListView1.Items(i).SubItems.Add(dt.Rows(i)(14).ToString).The second problem is.When I would like to edit, how can the datetimepicker get the listview value ?

I need some clarification. I'm planning to make a Scheduler program where it will fetch data from a MS Access Database, and I also want it to upload the data to a web server (MySQL Database) in JSON Format.
In the first process which is the fetching, I'll use System.Data.Ole.db namespace. This namespace mostly worked in MS Access. In the 2nd process which is the uploading, I am planning to use FTP protocol and should be JSON Format.
I was just confused with the second step, is FTP protocol applicable for this process?
I will make an Android apps to view all the data that will be saved on the web server.
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?

I want to create program in vb2008 express with ms access database. Can somebody help me so i can learn how to program using classes hard coded. I have learned vb6 before but it has a big difference on vb2008.
I have a database named "DATABASE" in ms access 2003 and the details are: Table :
All the CAPITALIZED name are Table and all items inside the parenthesis are fieldnames. I don't know where to start on working on this RECORDS. I was able to understand visual basic 6 a bit, and i am trying to apply the coding to VB 2008 but all i get is errors. I am hopeless now and i need help to be able to start my programs. If someone can give me a sample code, i think i would be able to trace the line of code to be able to understand it. I am currently an inventory manager on the small company i was working with and i like to organize my record by using database.
I'm having problems with the updating of my datagridview. I can update to the MS Access database. The problem is I cannot update to my datagridview!-[code]
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.
Using conProduct cmd1 = New OleDbCommand("UPDATE tblSODetails SET StartTime = " & soStartTime & " WHERE SO = " & CurSO & "", conProduct)
I have created a datagrid and populated it with data from a database. When the data is changed, I try to update the database and I get an error without any description of what the error is.to fill the grid:
dsjobs.Clear() With dbAdaptr 'populate jobs table Dim SQLStr As String = "Select * from jobs"
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.
