Okay what I have saves my stuff to the database. However, when I rebuild my application the previous data is gone. The data is loaded into datagridview using
My program runs with no errors, but the actual .accdb file does not reflect changes when I make them in the running program. Also when I fill in the text boxes and click the "Add New Item" Button, the "ID" text box displays a -1. "ID" is the primary key in my Access Database.
Imports System.Data.OleDb Public Class addMemberForm Inherits System.Windows.Forms.Form
I've seen used the datagridview to save the changes.
I don't use a dgv, but rather I connect directly to access and when a text field has text in it, it takes that text and searches, and updates various text boxes with the according information (finds a row, and takes all the data in the columns and adds it into their respective box). There are approximately 5-7 text boxes being used at the same time, and only a few will be changed.
How would I go about updating and saving through the VB program?
Here are some relevant pieces of code:
Dim con As OleDbConnection = New OleDbConnection("Provider=Microsoft.jet.oledb.4.0;data source=C:\InventoryMusic.mdb")
I have a function that i use to save a datagridview row to an access database (which works fine) but i was wondering any one know what i should look up to figure out how to set the row that i am saving to a colour IN the access database. So the row that i save is say red in the access database.
am pretty new to VB and i am slowly teaching myself .I am working on a project at the moment which will write to an access database. I have created the database with contains about 40 fields. i Have a form which the user inputs the data into whose controls are bound to the corresponding fields in the database . I have been reading up on what a could but the more i read the more lost i am getting.
Private Sub Table1BindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Table1BindingNavigatorSaveItem.Click Dim dg As DialogResult = MessageBox.Show("Would you like to continue saving your changes?", "Save Changes?", MessageBoxButtons.YesNo)
I have a MS Access database file that I can view with a DataGridView, but I can not save the changes made. User should be able to modify data, and when pressing the "Save" button, these changes should be reflected on the database. That is not happening.I know this is a common question, but I have read dozens of pages trying yo get this to work.

I'm struggling to work with data in VB 2008, and find it extremely complicated! At first I couldn't even get a database to load, as VB 2008 kept complaining it was created with an older Jet engine.OK, I converted it to a newer Access format that VB 2008 finally accepted.
In trying to find out why changes weren't saved, I found a common problem was VB 2008 wiping out changes.OK I have told the compiler not to copy the older database file back over but to copy newer.Updates then supposedly happened --- no errors were reported --- but the changes were still not saved.It appears the update method didn't exist in the datatableadapter, but I got no error messages about that. No update done.
I've used the tools to configure the dataset and datatableadapter.Automatic generation of methods like update, add new, delete, etc. were supposedly done.Now, when trapping the error, I'm told the update method isn't a valid one.I found little information on that. It suggested primary keys could be a cause, but adding or deleting a primary key has no effect.I can see the fill method, and it works fine.I can't see the update method. (Apparently it is in SQL which I don't know anyway.)
I'm working on a simple data logging program, and I have little to no database experience. I wrote a little VB forms app to log the data to ms access and then graph the data, but I'm having trouble with adding records to the database. First, I created a simple one table database in access. Then, I added the database to the project as a data source, and gave it a data set using the wizard. Right now my code looks like this:
[Code]...
There are no problems during build or run time, but I do not see changes to database after the program runs.
I'm trying to create a simple Data Grid that will automatically save changes. So far I have a data grid connected to a MS Access 2007 Database that reads the data. I can create new fields in the Data Grid, but I need to program to save the data automatically to the database on update (or on close).
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 ? [code] info: using access 2003 (.mdb) the Date of Birth field has been set into Date/Time.
I have an application that has an Ms Access 2007 DataBase which runns great if access is installed. Is there any code that I can use in vb that I would be able to run access with out installing it.
I have two Access database, say database One.mdb and Two.mdb. I want to use VB2005 to export tblCustomer from One.mdb to Two.mdb, and replace the existing tblCustomer in Two.mdb, during run time. I basically want to simulate the export function that is available in MS Access (which can export one table from one Access database to another) with VB2005 during run time. I can think of a way by querying the table to a dataset and then delete everything on the other database before filling the table in that database with the dataset
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?
What is the code to save changes made in a project to a database (MS Access).I have a program which is a database controller for DVDs that I own, and I have all the text boxes etc there, but I have no idea how to save records to the database.
I need to make a program in visual basic that when the user presses submit on form2 it saves all the following info from the textboxes to table1 in the database.
UserID (on form1), Reelno (on form2), Weight (on form2)
I'm trying to save scorecard information from a visualbasic program to an access databasse. I have tried binding the text boxes but am unable to fill the text boxes with the appropriate information. So i have tried the following code:
Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click Dim MySC As OleDbConnection Dim Command As OleDbCommand
[code]....
The program runs completely and has no build errors, but I receive the following error when click on the save button.
Unrecognized database format 'F:\CINS137\BlueYahtz Solution\BlueYahtzScore.accdb'.-Microsoft JET Database Engine
I have a VB2008 programme that accesses and stores data in a MS Access (XP) Database. I also live in the UK and am use to our funny old ways with dates (today is the 5th April 2010 so I want the Short Date as 05/04/2010 not 04/05/2010)
I am using the following code
Dim d1 As DateTime = DateTime.Now (#04/05/2010#) Dim why As String = FormatDateTime(CDate(d1), DateFormat.ShortDate) which is 05/04/2020 UpdateRecord("latest", why, "backups", (index value in the table)
The last line runs an SQL query to update the table column latest to the date today but whatever I do to get the date as 05/04/2010 it is saved as 04/05/2010. I have tried setting the culture to "en-GB" at the start but this does not work. It does not matter if the latest column is in Date/Time or String format
