Looping Through Data Grid View And Inserting Values Into Database?

Apr 5, 2011

Currently I have a problem with updating my database with values in my Data Grid View.

On my form I have a "Populate" button and "Submit Details" button.

The "Populate" button fills my Data Grid with numerous lines of data.

On the click event for "Submit Details" I want this data to be inserted into a table in my DataBase by looping through each record.

For Each dgi As DataGridView In DataGridView1.Rows

Dim productCode As String = DirectCast(dgi.FindControl("product"), Label).Text
Dim description As String = DirectCast(dgi.FindControl("description"), Label).Text
Dim quantity As String = DirectCast(dgi.FindControl("order_qty"), Label).Text

Compare Values In Datagridview With Values In Database Before Inserting Into Database

Dec 15, 2010

I am building VB.NET application that takes data from text files that are exported from a legacy DOS program. These are written to a datatable and displayed in a datagridview. Right now my code simply loops through the datagridview and inserts the data into the database (SQL Server). There is a requirement now that the client number must be checked before the insert to see if it exists in the database. If it does, then the value of one field (tax rate) is checked against the value of the field in the datagridview. If there is a difference, then the rate is to be updated in the database and the data that was in the database is to be written to a history table for audit purposes. If the client number is not there, then we are to do the insert (which is already written). I want to know what is the most elegant and efficient solution for this problem.

I need to compare what is in the database table with what is in the datagridview, update the history table for records that exist, and then insert new records.

Database - How To Deal With Inserting Values Into Two Tables When Exception Occurs

Jul 21, 2010

I have 2 tables loginInfo and UserInfo. LoginInfo Stores username and passwords while userinfo stores other user details such as Address,postalcode,phone etc.

I insert values into loginInfo first and if successful I enter the userInfo details. If exception occurs while entering details into userInfo i delete the loginInfo details.

This is how I do now

'login details are entered successfully
If CreateLogin(uName.uPass) Then
Try
'Create the user details

[Code]...

Is there a better way to deal with this situation? can use Transactions?

VB Not Inserting A Row Into An Access Database?

Apr 6, 2011

I'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.

Getting Cell Values Into Variables In DataGridView Based On Grid Coordinates?

Mar 20, 2011

Im working with a DataGridView with an imported CSV file where the values are delimited with (,).. The grid works perfectly fine. My ultimate goal is to hide the grid out of view from the user and access the data in the grid based on the coordinates of the grid specified i.e (The cell in column 5, row 6 contains the value "Taco") and I want to save that value to a variable...Eventually I want to loop through all the values of a column and save them to individual variables to be later used. So far, this is what I have...

Dim sReader As New StreamReader("book1.csv")
Dim Record() As String
For x As Integer = 0 To 17[code]....

Presently, that will only display the data in column 0, row 0 in those labels...

Note: 17 in the for loop is the amount of columns in the data i provided.. that number will never change.

Inserting Data From One Access Database Into Another?

Jun 6, 2012

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
