Add, Delete, Save Data From VB2008 To MS Access 2003?
Jun 21, 2010
I'mvery new to VB2008 and have basically no idea regarding much of coding. I have attached a copy of my form. Basically, I have a db named "employee.mdb" with table "Employee". It has 3 fields Name, Dept and Designation. I want to connect my db with the form and want the following functions (when the respective buttons are clicked)Add: Add a new record to the db and save it without overwriting an existing record.Delete: Delete the selected record from the dbSave: Save all details<<: Move to the previous record>>: Move to the next record. I hope I have explained myself clearly
I need to be able to save, edit, and delete records in an access database through vb2008. Editing and deleting records works perfect, but I cannot save new records. Can anyone assist?
Here is my code
Imports System.Data.OleDb Public Class Main_Form Dim con As OleDbConnection Dim cmd As OleDbCommand
I am using vb2008 express to work an Access 2003 database. I want to use code to delete the table after I have used it and before I close the program. Is there any code to accomplishg this?
I am doing a project on creating a database using vb.net. I need to be able to add records, save, delete and retrieve these data. I am a beginner so far I have created the design I need to be able to link many forms such as order form, find customers, add customers etc. How do i go about this.
I am using MS Access 2007 as database and VB 2008 to build an application to show the content of 2 tables as a single table.I have two tables in MS Access and i have linked both the tables using "ID" as primary key(1st Table),foreign key(2nd Table). I used Query Wizard to show the data of both tables in a single table(3rd Table).I am able to view the content of all 3 tables using datagridview in vb 2008(Using Code), but i am unable to add,delete,save and search the content of the table using code. My concern is,i will be able to do all these operations using codes only.Would you please help me out in this.
Whilst writing a routine in Access I founf it rather fiddly for user...was thinking it would be much better for them to click a button in VB.net and that would do all the hard work.
So is it possible to do these task against a Acecss 2007 database
-Delete table -Compact database (to clear out table) -then run query to remake table
I have a datagrid being filled by the data adapater connected to my database.I have a delete button on the form, i cant figure out how to delete the selected row on the datagrid when the delete button is clicked.
I have a Visual Basic 2008 Windows form application that processes some scores and data. I want to export the data to an Access database. I have created the Access database and connected it to the VB program.I am looking for a simple set of commands or sample code to add records to the database. Perhaps I am oversimplifying the problem, but it seems like it should be so much easier than it has proven to be. I only want to export the data in code; the user should never see the database or do anything to it while the program is running.
I'm using VB2008 with MS Access Database.I make connection with DB by using the automatically way (by add a new data source ....)I create the Sql in "SELECT id, na, num FROM Table1" by add query to Table1TableAdapter, and add this code in form to call the sql :
Me.Table1TableAdapter.Fill(Me.AcddDataSet.Table1) And it succeed with me I tried same way with insert data to DB like this
Is it possible to pass data between a MODULE in Access and a VB2008 app?
To be more specific, suppose a VB app calls a MODULE in a access DB and the job of the module is to count the number of records that have "Joe" in a column. I know this can be done with a SELECT within the bindingsource BUT in some instances, it is much faster to pass the task to Access and return the result.
So - can an Access MODULE RETURN a value back to a VB app?
i have encountered this error Variable 'dsNewRow' is used before it has been assigned a value. A null reference exception could result at runtime when i click on the button to insert data into my ms access database.
I have some code that retrieves some data from multiple tables.This works fine.Now I want the data I retrieved to ADD to an excisting table in an Access 2003 DB.

The code I use to retrieve the data from sql server 2005: Dim connection As New SqlConnection(strConnectionStringSQL)
I have two tables in one to many relationship in an access 2003 database.I am using vb6 and visual studio 2008.I want a data entry form (in grid view) for child table. I want to display & add, Update, delete child records accordingly with parent.
i.e. What I require is One combo box displaying a parent field and corresponding child entries will be shown in grid view. Data entry form for parent table may be on separate form.Is there a full sample source code for above mentioned theme.
I'm trying to retrieve data from an Access database - a simple one. (Just a single table with one column) My task is to view these records through a 'ListView'. No need to manipulate or anything. Just to retrieve data with a simple SQL statement and display via a ListView.
A simple database has been created in Access, which is just basically a table of text, with some images as entries. A form has been created in VB2008 Express and linked to the database. Either a combibox, text boxes or pictureboxes are linked to a column form the database. The first row entries are all displayed correctly in the relavant boxes (except for the images, which for some reason aren't displayed). If another value in the comibox is selected, the other box values don't change and there is still no images visible...
I have a BindingNavigator1 binding to a datasoure. In default, we can add,delete, save data with BindingNavigator1 control. i want to know : how can i write more code to event click of "delete" button(or add , save button) in BindingNavigator1.
Example : i mean i want show messagebox yesno before delete operation is performed. if result = yes then delete. i tried this but not yet :
i m using fallowing code for update, delete and save data it's working very well when i save new recored but when i update and delete recored it's showing error message "Dynamic SQL generation for the DeleteCommand is not supported against a SelectCommand that does not return any key column information."
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click If thismode = 0 Then row = ds.Tables("state").NewRow() row.Item("state") = TextBox1.Text
I was wondering if there is a code i could add to my applicatio that will delete a data entry from a database. I'm designing a voting application as my project and i want a situation where an access code is good for only one entry. i put my code for retrieving the code below.
Is there anything that i can add to the code that will delete the entry that was used to login immediately after authentication?
Private Sub btnCodeEnter_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCodeEnter.Click Dim connect As String Dim query As String Dim dbProvider As String Dim dbsource As String
Working on Access 2007 and Visual Studio 2008, i already connected my database to the application and can see the data on datagrids and can add or edit or delete records, the problem is that those changes do not go to the database, so when i close and reopen the application, i found the old data as it was before. Note: i used the wizard to add the connection, not the code.
Why my delete button wasn't work. it say "InvalidOperationException was unhandled' at m_daDataAdapter.Update(m_dtContact). What that means?[font=Arial Black]
Public Class Form1 Private m_cnADONetConnection As New OleDb.OleDbConnection() Private m_daDataAdapter As OleDb.OleDbDataAdapter Private m_cbCommandBuilder As OleDb.OleDbCommandBuilder
