Can't Get Datagridview To Write Back To MS Access Database
Oct 3, 2011
I am using MS Access 2003 and vb.net to develop a windows application of inventory management.
I have used datagridview in the form and using FillBytoolstrip option, can filter data using type.
But i have no idea as to how can i update the database to reflect the latest changes in the gridview.
following is the code I have used.
Private Sub BOM_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.PartnoTableAdapter.Fill(Me.HemDatabase1DataSet3.partno)
End Sub
I loaded a dataset (just one table) from the database. Then I modified f.e. the rows from 5 to the end and add 4 new rows. Now, I would like to write back the dataset into the database.
I am having a problem with an application that displays data in datagridview depending on a selection from a combo box.The problem occurs when I want to write the data back to the database.
I get the following error:"Update unable to find TableMapping['Product'] or DataTable 'Product'."
Is this because the table in the dataset is filled in a private sub? If so how do I make it public?
I have this problem, I can create a setup for my app/database but everyone can open the backend file which is an MS Access database. I want it so we can only access the database using the frontend app.
can anyone teach me how to save data in microsoft access database and retrieving it back from database?[code]so, how do i save it in that and how do i load their data by typing their ic no only..
I am using the code shown below to compare two Access databases with two fields each and write the results to a third Access database. I am getting an error at the "Do While DMReader02.Read = True" line: "Invalid attempt to call Read when reader is closed." Why would the reader be closed at this point if I am using different DataReaders in the two loops?
I am developing a Visual Basic .NET application to be used by the staff of a small training centre nearby. The front-end (UI, menus, etc.) will all be in VB .NET, and there will be a back-end database for storing all of the required data, such as student records and meeting information. What I would like to know is if it's possible to use a Microsoft Access database for this purpose, and have it accessible by all the staff in the centre (on the same network) at the same time. For example, would I be able to put the database in a shared network folder, and have a copy of the VB application on each PC that would all be able to read/edit/add to the database?
I have an app written in vb2005 that allows users to search a sql database for a store name. Once a store is selected, it then presents the user with 12 different tabs, each with a DataGridView showing various bits of info about the store. It's a large and convoluted database, so I'm using stored proceedures to pull the data for each tab. Here's a sample of one of the subs that populates the tabs.[code...]
Now, this works just fine to populate the grids on the tabs, and the same code is copied into each of the subs that fill the grids (changing the stored proc, parameter and grid names, of course). The problem I'm having is how to move changes made to the data in the grid back into the database.
I have stored procs that do this (and the procs do work), I just can't seem to figure out how to trigger the stored proc when the user makes a change.
If it matters, there is only a grid on each tab, I did not use a binding source as I am trying to keep an abstraction layer between the data and the app. I did create a dataset, which is how I gain access to the stored procs, but I left the grids unbound and (as seen in my code) bind them at run time.
Dim da2 As OleDb.OleDbDataAdapter Dim cols As Integer = Attendance_QueryDataGridView.ColumnCount Dim rows As Integer = Attendance_QueryDataGridView.Rows.Count
I have an application running with a access db. I have written some code to copy & zip the db file to another location (selected by the user) for the purpose of backup. (I am using sharpzipwrapper)Whenever I try to run the code for the copying & zipping it gives me an exception saying that the file cannot be zipped as it is use.Do I have to close all open connections in order to backup the .accdb file? If yes then how? else what do i have to do inorder to get 'access' to the file.Do I have to exit the application to close all connections? These connections are written in code for e.g. :
I can edit the values in the dgv cells manually, add rows, delete rows all without problem and then update the database.My problem is in one form where I want to allow the user to filter the rows in the grid and then enter a value in a textbox and programmatically update all the cells in one column with that valueI can update the rows, and see the changes in the datagridview. When I try and update the database (using UpdateQuery on the underlying TableAdapter of the datagird) only some of thechanged rows are being updated I though it might be related
I've got a question below:load data from a table in database into a datagridview,make change in datagridview,and use update function to update change back to tablebut 13 changes, only 12 being update back to databaseonly the top row on the datagridview not being update??
For Each orow As DataGridViewRow In DataGridView1.Rows orow.Cells(1).Value = TextBox1.Text Next
I am using VB2005. I am trying to write to an Access database seperate from the data's origin. AKA: I need to run a query getting data from one Access table and write it to a table in another Access database.
Overview: I need to get data from one Access table and two Excel worksheets. I need to write the data to an Access database so I can run a query combining the three into one table. I will then use the table to create reports.
I have googled, checked multiple sites, and checked MSDN. The only thing I have been able to find is populating a datatable and writing changes back to the database. This was SO easy in VB6.
I'm trying to write data from an excel spreadsheet to an Access database. When i run my program a message appears saying that the correct number of records have been saved, however when i check my access database no records have been written to the database table.
The following is a copy of my code (sorry i've just edited it to get rid of the white space that was added when i included it here for some reason.The code for writing to database:
Public Class Form1 Dim connection As OleDbConnection Dim Command As OleDbCommand
i've download the 101 Visual Basic and C# Code Samples from downloads/details.aspx?familyid=08E3D5F8-033D-420B-A3B1-3074505C03F3&displaylang=en i was going to learn "VB.NET - Data Access - Read and Write Images from a Database" from that 101. the program is written in 2003 the conversion of the problem to 2005 and 2008 failed.
What I am trying to do basically is open an access query in a datagrid view and then be able to make changes to the datagrid and then save it back to the database.When I try to save:
How can i send a table values into DataGridView? I am using Access Database.And one more thing i want to know that.Before sending values into Datagridview i need to work 2 or 3 tables and that result should be keep one Temp Table , that TempTable i want send to DataGridView.Here 2 or 3 tables work means i want to applay leftjoin between two tables and coming result should be keep one temptable and again i want to right join with temptable to other table.This Concept i recently worked on VB, now i want to do work on VB.NET.Is there any way to handel this task? Any i how i am sending Code which i implemented same concept in VB.[code]Here in VB code i used Functions, i called Functions in the FORM and i declared the Functions in the Module. By using Funtions and Recordset i did job. But how can i handle in VB.NET?
I have a little problem with converting data from a datagridview to my access 2007 atabase.t's been some years since the last time I've opened Visual Studio 2008. So, probably it's something easyo do.
This is my code so far: Dim i As Byte = 0 While i <> dgInput.Rows.Count
I have Access database that I am connecting to as such:
Public dbE As DAO.DBEngine Public db As DAO.Database Public sql As String
[Code]....
While I can query for certain data, I want to know how to show a whole table in DataGridView. For example, I have a table called phoneNumbers and I want to show the whole thing in DataGridView3 instead of parts of it.
