Retrieve The Data From A Specific Row And Column From A DataSet?

Aug 19, 2009

I know this has to be a very simple answer but I seem to be overlooking it. I have an Access database that I have conected to and have created a DataSet. The DataSet consists of one table with several rows and a bunch of columns. What I am trying to do is get the data for one specific row and column so that I can use this data is some calculations. I can position the row if I need to but I can't figure out how to get the data in the specific column I need.

VS 2008 Finding A Specific Row And Specific Columns In Data Base File (Access)?

Jul 24, 2011

I wonder if it is possible to find a specific row and specific columns in data base file (Access) . You see , I am using a DataGridView control to show only SOME of the columns (fields) of a table from an Access file . For example , lets say that in the DataGridView control I only show the following fields :Field1 , Field2 and Field3 .Now , when the user selects an entry in the DataGridView control , I want to insert the text from Field4 into a text box on the form .

The problem , however , is that I don't know how to get the specific row in the data base file and also I don't know how to get the text in column (field) Field4 of that row .One thing that might be important is that the index of the row in the data base file is not necessarily the same with the index of the current row in the DataGridView control . This is because in the DataGridView control the rows are order by the contents in the ID Field .ol .

System.Data.Common.DbDataAdapter.Fill(DataSet DataSet)

May 14, 2012

I have tried everything I can to get beyond this error which shows below as <<<<< error here. It is trying to fill a dataset from a data adapter. If I change the SELECT statement to just SELECT * FROM xTable I get the correct number of records in each table. But anytime I try with a more complex statement I get the error message shown below which indicates System.Data.Common.DbDataAdapter.Fill(DataSet dataSet. I've completely erased all data and entered a new set of test data so I know there is no problem with relationships. Each table has primary key which is foreign key in other table. IS there something wrong with the Imports section: Imports System

VS 2010 - Search Dataset For Specific Record

Aug 1, 2011

My application will start (dataset filtered by username/date) and if it's the first time the user has used it today it will be a blank entry form because there is no record for today created. The user can just type data into the blank form and close it. On the form closing event I want it to run a tableadapter.insert(username, date, x,x,x).

If it starts a second time it will load showing today's entry because today's date was inserted previously when they closed the form. So this time when they close the form I want the form closing event to just run a tableadapter.updateall(dataset) command. I need some help with my form closing event...

Writing To Specific Cell Located In DataTable From DataSet?

Aug 14, 2011

I'm trying to write to a specific cell located in the datatable, which is from dataset. I know that it would be datagridview1.rows(xx).columns(xx).value=(""). But how to do it in a datatable

Public Class Form1
Dim ds As New DataSet1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim TestValue As String = "test value"

The following code above does write to column 3 row 1, but if you say .rows(1), i get "there is no row at position 1". So, in summary if I have 7 columns, and I created a second row I want to write to column 3 and the 2nd row.

Add Data To A Typed Dataset?

Jun 25, 2010

I created a dataset in Visual Studio 2010 containing two tables: tblCategories and tblAnswers. tblCategories has two columns: CategoryNumber (AutoNumber and primary key) and CategoryName. tblAnswers has three columns: AnswerNumber (AutoNumber and primary key), Answer, and CategoryNumber. The CategoryNumber columns in each table are related. I have a command button which I want to use to add a record to the CategoryName column in tblCategories with the data typed in a textbox. When I try to access the dataset to add a new row(dataset.tblCategoriesDataTable.NewRow), the NewRow method isn't present. I've done some reading which suggests that I need a TableAdapter, but it seems like that is for connecting to an external file because I have to select a connection. I have no external SQL files or database. I want the user to be able to create a database within my program.

Copy Data From 1Db To Another Using Dataset?

Oct 24, 2011

I need to copy all data from a Table of a Acces mdb (connected with OleDB) to a Table of a MySql DB (connected with ODBC)

I made a working solution, but it's very slow, and so I want to try other solutions to check if they can give me more performance.

The solution connecting to the mdb, using a DataReader, then for each row in Datareader I make an INSERT into the Mysql Table ( before copy I truncate the table to get it empty)

The records are more than 10K and this operation is very slow, and do be onest I need to do the same thing on other 2 tables also very big as this one.

I cannot make a direct sql insert ( as INSERT INTO A in ..... SELECT * FROM B) because the 1 DB has a OleDB conn and the other has a ODBC conn.

So I thought to try to make this operation using TableAdapters and DataSet, but I'm not able to make it working.

The problem is that the Dataset's HasChanges is false

If you need some code I can post, but what I do is following:

Connection to MDb
Create OleDbTableAdapter
Create DataSet

I have a very simple DataSet linked to a ListBox. I need the User to be able to add Data and have used the following code (in a ToolStrip command button):

Dim newFileRow As DataRow = Database1DataSet.Tables("tbl_Files").NewRow()
newFileRow("File Name") = fleName
newFileRow("File Path") = flePath

[Code]....

This seems to work ok - the new Data immediately appears in the ListBox. However, as soon as I close the form all of the Data in the DataSet is lost.

There are many students and many classes and each student is a member of a class.I then have a windows form that needs to display a list of student names in a listbox. However, I have a different form for each class. So for example in this form I have coded below, I need to display all students that are members of class51. The code I have so far is reading in all students from tblStudent and this is not what I want. I know that if I was doing SQL or something I'd simply write SELECT * FROM TBLSTUDENT WHERE CLASSID =his?
