System.Data.Common.DbDataAdapter.Fill(DataSet DataSet)
May 14, 2012I 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

Autorefresh Windows Form - Dataset To Fill The Datagridview?
Apr 16, 2009I am working on VB.Net. I have a sub form with a datagridview, that is being loaded with the criteria taken from another form. Hence this form is called with parameters. Here is the code that calls the sub form.

Here is the code in the sub form.

Using A Dataset To Fill Datagrid In Form - Assign A Color To The Forum "where =open/closed"?
Aug 4, 2009Im using a dataset to display data in a datagrid from a sql server DB. One of the colums I have in my datagrid is "Status" the table adapter sql statment selects certain items based on whether there open or closed e.g "where = Open ". I want to remove this row entirely and instead of displaying open or closed for status column, display the open/ closed results in colour on the datagrid. Im really not sure how to go about this whether i need to do it in the table adapter or some sort of property. I presume i need to write a sql statement and selct the identity of the row where x= open etc , is there a way of assigning a colour in sql statement so it displays on my vb form ?

View 2 RepliesFill Bound DataSet In Backgroundworker?
Jul 10, 2010I've added a Data Source to my project and a table from that Database (SQL 2005)
It is a rather large table and takes a LONG time to load the form. I was thinking of loading the auto-generated "Fill" statement in a Backgroundworker, but it doesn't seem to be doing anything. I have the Fill statement in the DoWork event, but it never "finishes" it seems. My BindingNavigator stays at 0.
I looked at jmc's sig link and everywhere I look, it seems like I'm going to have to iterate one at a time, but how can I do this for a bound datasource?

Fill A Dataset From A Visual FoxPro Table?
May 4, 2010I think what I have here is an environmental issue. When I attempt to fill a dataset from a VFP table I am getting an error message that says "Index Not Found". The reason I feel its environmental is because the process was working perfectly fine last week. The client I am trying to run this program for runs it once per month to integrate one of their FoxPro systems with SQL. It's been in working order since November of last year, but suddenly now I'm getting this error. Some things I have looked at already are updating VFP drivers for both OleDB and ODBC.

Possible To Fill A Collection-Type Instead Of A DataTable/DataSet?
Aug 4, 2010this is more a theoretical question i asked myself.I remembered that BinarySearch of an ordered List(Collection in general) is faster than finding Rows with Datatable.Rows.Find or DataTable.FindByPK with a primary key value.Hence i fill a Datatable from Database in a shared constructor and immediately after that a List(of Int32) that contains all primary keys from that table. Later i will check with BinarySearch if the List contains primary-key values. But because the datatable contains only the PK-Column anyway, i asked myself if there is a way to avoid the huge overhead of filling a Datatable and after that adding all Rows to a List. Is it possible to fill a generic List(or other collection-type) instead of a Datatable/Dataset directly from a Dataadapter?Maybe i'm off the track and there is another way to avoid the Extra-Loop that i'm missing.
The code of filling the DataTable in a strong typed Dataset and the List:
Private Shared w205CorrectSWUpgrades As New List(Of Int32)
Shared Sub New()

View 3 RepliesDataSet Has Errors In Multiple Cells After Fill Method?
Mar 2, 2012I am experiencing something very bizarre when I execute the Fill method of my adapter. I've been running this query for months and all of the sudden this is happening after I installed SP1 for Visual Studio 2008. For some reason several DataRows in 2 of the 3 tables within my DataSet have errors in them when I view them in debug mode using the DataSet Visualizer. Here is a picture of what I'm talking about
It does this to random rows. If I execute the Fill method the first time, rows (5-10) will have these errors. If I execute the Fill method again rows 12-23 are affected and so on. I have no idea what is happening here.
This is effected my DataGridViews, because they don't display any rows, because of the erros. I should also note that when I run the lines of code below in the Immediate Window it says the DataSet doesn't have errors.
?Me.ds.Tables("Current").HasErrors
False
?Me.ds.HasErrors
False
DB/Reporting :: Fill Access Database Table From Dataset?
Jun 5, 2011I have 2 databases that I am working with. One is a compant customer database and the other is my personal call log. Now I am creating a front end for the Call Log. I was updating my customer list by Importing 2 tables from the customer database, a series of queries would erase all of my info, take all the data from the imported tables and move it into mine then erase the imported tables.
Im trying to accomplish the same in my VB frontend. I can connect and fill datasets from the customer database. I can erase my tables. How do I take all of this data from the newly created dataset and move it over to my empty tables?

Apr 29, 2010I have a SQL Server database for which I have created a strongly-typed DataSet (using the DataSet Designer in Visual Studio 2008), so all the adapters and select commands and whatnot were created for me by the wizard.
It's a small database with largely static data, so I would like to pull the contents of this DB in its entirety into my application at startup, and then grab individual pieces of data as needed using LINQ. Rather than hard-code each adapter Fill call, I would like to see if there is a way to automate this (possibly via Reflection). [code]...
