Combo + Datagridview + Inserting Grid Values To Access Database?
Jan 15, 2012
I followed the suggestion from [URL].. this thread. however i face a bit of a problem in my case i have a combobox at row(i).cells(0) the code seems to take the last new rows where there's not record and shows error the debug error msg is A first chance exception of type 'System.Data.OleDb.OleDbException' occurred in System.Data.dll INSERT into taken(typeID,quantity) VALUES (5,39)INSERT into taken(typeID,quantity) VALUES (,)
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
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.
I generate a DataGridView using the result of a query. The query generates a LOT of columns (more than 75). Obviously the DataGridView does not show all of them. I wrote a small procedure that extracts data from the DataGridView and generates an Excel file ora .csv file.
I have a datagridview which contains 4 records. I want to insert these records into access table. This access table already have records. Datagridview's columns & access table's columns are same (datatype & columnname). How can I insert these 4 records in access table?
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.
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.

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.
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 am trying to enter a record into an Access database via visual basic programatically.I had this working fine when I had the datagrid bound to the database but now I have decided to do it all at runtime to save on resources at runtime.When I unbound everything and tried running it with my existing code
Try ds.Tables( "tblProduction").Rows.Add(row)
This is the line of code that has to have another 30 entries in it.
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
Dim purchasedatetime As Date = Now 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?
I am trying to insert records in an Access database using VB.NET 2008 using the following code:[code]I get this error Syntax error (Missing operator) in query expression when I try to insert any record that has apostrophes in the name.I have tried everything I can think of to get these types of names intserted into the database with no luck.
For some reason my code is executing the INSERT query twice and putting duplicate records in my table. If I put a primary key on one of the fields I get a runtime error and it complains about the fact it can't add the record twice.The part of the code that INSERTs is near the bottom, bolded and italicized. I put the entire IF statement of code incase my logic is wrong.This is what's being executed when a user clicks a button
If listOfCompanies.Contains(cbx_Company.Text) Then 'If the list contains the company, UPDATE the record If LaborChecked Then
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.

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. If I enter a record into the table in Access it automatically enters the next valid ID however when I can't seem to make this happen when entering data via my VB form!
I have a datagridview with a combobox coloumn. A few items have veen added to it. (Say Furniture, Property etc.).I wish when I select Property, the column 2 of my current row should get text Property.Which event to be fired for this. I tried _CellValueChanged etc. but that did not work.
I am trying my hands on VB.net and is trying out a small application which includes a survey form. The form contains radio buttons and when the respondent clicks on a radiobutton, digit '1' should be placed into the relevant field of the database.I have established a dataset and tried doing it but not sure how to do it because the book (How to program Visual Basic.Net by Dietel) does not teach us that
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 am trying to insert into a access db and the PK is an autonumber that is generated by the DB. I am getting a syntax error for the insert statement and dont know why. If possible I would like to return the autonumber value in the same statement.
how to get my data out of access and to a data grid. What i want to do is, edit this data in the the data grid and save all alterations to the data grid back to access. There must be a command which copies all the contents of the data grid back to the access database??
I'm trying to bind a combo box to a Access database field. I'm trying to do this with code instead of using the data sources wizard as I was told that this would be more flexible and better if distributing the finished program to other computers.
The result is that the form runs, but nothing is in the combo box.
I have also not used a dataset in my code, only a data table. Am I correct in thinking that this is plausible?

I need to display an two-column editable grid not bound to a database. I took a look at ListView with Mode=Details, but it appears that only cells in the first column can be edited. I then took a look at DataGridView, and am having two issues:
1. When editing a cell, it adds a new row: [url] How can I prevent this?
2. I don't like the grey background and would like the grid to fill the whole space, right and below.
BTW, if you know of a good tutorial on using the DataGridView unbound, I'm interested. [Code]
I'm writing an asp.net page with a simple registration form that connects to my access database and inserts the values in the table. So I have my database, my registration page, everything looks fine in my code, but there's a syntax error I can't seem to figure out. When I go on my webpage and click submit, it says : Syntax error in INSERT INTO instruction.
I am using VB 2008 Express to connect to an Access 2007 database. I have a combo box that is populated by the database. When I used the Access report VBA, I used the AfterUpdate() event to calculate a sum and place the results in a text box. I need to know how to do the same operation in VB 2008 Express using the SelectedIndexChanged event of the combo box.
The combo box is called "cboYearMonth" and is populated by my database, this is working correctly.
The text box that I want the calculated results to appear in is called "ExactPagesTextbox"
I have a query in Access called "JobTypeExact_Query" that contains all the pages that I need. What I need to do is calculate the total number of "Pages" limited to the YEARMONTH selected in the combo box. YEARMONTH is a value in every record in this query.
I have a datagrid view containing a customer list that if if double click on a row it brings up a customer maintenance window. Once I hit a save bottom on the second form how can I automatically update the database, refresh the grid on the initial window but remain on the same row on form1 that I double clicked on in the first place. Currently I am re-loading the datagrid on the initial form with all the data once I close the second window down.
I created a dataset and i am using OleDbDataAdapter to insert new values to access database. But when i close the program and after open it, values are not in the database. How can i solve this problem? Also, i have another problem. When i write codes that
