I have a form showing a datagrid that is filled with info from an Access database table. The table only has 3 fields: two of them are string type and the third one is boolean. The first String type field is also the primary key (this field is called "clave"). This datagrid is supposed to let the user select one of the rows and then click on a button to delete that row. I'm trying to do that with the following code:

I have a VB front end for an Access database and all I need to do is assign the values from the front end onto an Access table,[code]Not sure what I am doing wrong, I have created something similar in VB6 but can not get my head around it in vb.net.
View 4 RepliesI'm working on a program for my company and have hit a wall in my knowledge of Visual Basic since it has been a few years since I've worked in it.I don't know how to insert a row into an access database. I've tried a bunch of different things I found on other forums and the like, but none of them worked. Right now i'm just using a Connection Object with ExecuteNonQuery() and it doesn't return any errors but it also does not add anything to the database.I've posted my code below.

When the form loads,the combobox dropdown list will be filled with the data already present in the database.This part is working fine in the below code that i did.But then comes the data insertion part.when data is inserted into database,a message box will display on button click.But on clicking ok in the message box,the data recently entered into the database is not displayed in the dropdown list..[code]If i close the form once and then reopen it,then it is being displayed properly.But I want the recently entered data to be displayed as soon as i click the ok button of the message box.

I have a deployed desktop application which uses an Access Database. I have a need to update the databases which are in the field by adding a few extra fields to some tables to support new functionality. Thedatabases is password protected.
The process I am following is to ship a new empty database which contains the new fields (these fields are set to not require entry, accept nulls and they are not indexed) and then add functionality to the application which selects the data from each table in the current deployed DB and inserts it into the same table new template database. Then I kill the original db, rename the new template to be the file used by the application.
I am using OLEDB to communicate with the database and have tried using an 'INSERT INTO' but cannot get the syntax right - I used this example[URL]..but it throws and invalid argument when I try to supply a database password

str = "Insert into Customer_Order (Order_Date) values ('" & purchasedate & "')"
cmd = New OleDbCommand(str, cn)
exe = cmd.ExecuteNonQuery
I am trying to insert Default dateTime into my databse however when I run this code it stores date but stores time as 10:00:00, Is there a way I can store the time without the seconds so it is like 10:00?

View 3 Replies[code] When insCommand.ExecuteNonQuery is executed, an exception with Error # -2147217900 is thrown, with the detail of "In order to evaluate an indexed property, the property must be qualified and the arguments must be explicitly supplied by the user." At the time the error is thrown, this is what resides in strInsert: "Insert Into ScoutInfo (ScoutID, YearID, GSUSAID, FName, LName, DoB, Grade, Level, School, YearsIn, CurrentYear) Values (10000, 20092010, 123456, 'Jacobina', 'Lowe', '11/30/2009', 'K', 'Daisy', 'Thisone', 0, '20092010')" I've already verified that the Insert statement and datatypes of the columns match.

I have managed to successfully create a logon page and have created a form to insert data into one of my tables using text boxes and a "Save" button, however the first field in the table is the named "CustomerID" and is set to Autonumber, this is the primary key of the table.
