Could Not Get Type Information For Dataset

May 31, 2006

I started a vb form project and tried to add a data adapter and dataset to the project. Using the "Add new data source" wizard,

I get the error: "Could not get type information for ...dataset" I have tested this with two dB's and get the same error each time. One was the master db and the other was a dB that is custom. The stored Proc's are very simple, the first I tried was

Select name from Sysdatabases;

The other was one that had worked in VS2003 in another project.

VS2005 Pro, VB project on Windows XP sp2, SQL 2000 sp4 on a windows 2003sp1 enterprise server.

Dataset Field Not Able To Contain Enough Information?

Mar 7, 2012

So I have a form that uses a datagrid with checkbox selections for multiple (read as many!) items.When I click a button labeled "Save to file", all the information on the form, to include the values of the selected datagrid items are then saved to a database. It works great most of the time.However, I have found that if I select more than 3 items in the datagrid, I get an error pointing to the data set and data adapter stating "OleDbException was unhandled - The field is too small to accept the amount of data you attempted to add.Try inserting or pasting less data".The code it points to is:

da.update(ds, "TrainingRecords")

In the dataset, I have tried to change the max length of the associated field.It was set at 255, and as long as I stay under that, I seem to be fine. But if I go over it, I get the error. I can change the design I guess to make it less wordy and therefore store less data, but is there an easier way?

Filling Table In DataSet And Filter Information

Apr 6, 2009

When I use a command such as:
Me
.TableAdapter.Fill(Me.SomeDataSet.Table)

I am going out to the database, gathering the requested information and filling the dataset. Therefore, everytime I add a query to a table adapter, it is also going to the database to get the information. So, my question is, how do I fill a table in a data set with all the records in the database table and then, filter the information I've already collected in the dataset without going back out to the database again?

Application Reads Information From An Excel Spreadsheet Into A DataSet

Jul 15, 2010

My application reads information from an Excel spreadsheet into a DataSet (ds1) which is then filtered into another DataSet (ds2) based on user-specified criteria. The information is basically telephone call logs that reflects when a phone call was made,what extension it was made one, how long the call was, what number was called, etc.When the user's "search" criteria is matched in ds1 above, the application adds the number called to a ListBox on the form. When the ListBox Item is selected, additional information (call duration and such) is displayed to the right of the ListBox. My problem is that a single phone number could have been called multiple times on an extension within the date range the user specifies and for each occurrence of that number in the ListBox, the "expanded" info only reflects the information for the 1st call to that number listed in the DataSet.

The only unique identifier I have is the DateTime field for the row (as this goes up to the second). I thought about putting it into the ListBox item, but I'd prefer that this date not be visible until the user selects the ListBox item to view the details for that call. [code]

VS 2005 Getting Information From DataSet To Populate Defaults In Controls?

Jan 27, 2011

I have a form that has many controls. My next task is to populate the phone number (MaskedTextBox) and phone number type (ComboBox) when the cursor has lost focus from a ComboBox that has auto complete functionality. I have tried to do it and when the cursor leaves focus, the other controls are not populated. Nothing happens. I do not get any errors either. Screen shot attached for the form and I am also using a stored procedure to do this. There are two tables in question here. A client table that the name and phone number and then the second table that has the phone number type (cell, work, home, etc).There is an FK relationship between the two.

This is my stored procedure. It is called sp_GetClientInfoByName.
vb
CREATE PROCEDURE sp_GetClientInfoByName

.net - Do Classes Serialized As Object Lose Their Type Information

Apr 2, 2012

I have a serializable Message class that has a Data As Object property that I'm using as a generic holder for information to be sent via a system that uses a combination of push technology and/or IPC to communicate with any other programs that are interested in the information. This allows the communication piece to be agnostic of the information it transmits.

I was serializing this Data As Object as a Byte[], since I was worried about how an Object being serialized and transmitted across the network would behave on the other side. However, when deserializing I get errors about being unable to find the assembly for the types stored within my Data As Object property, because I'm deserializing in the assembly that contains the Message class... not the assembly that contains the type that Data As Object originally was.I was wondering if I'd lose the type information and be unable to cast it back to the type I want at the other end. Perhaps it's not possible to pass a type as an Object via another assembly without it knowing about my type?

How To Chose Data Type Of Column In DataSet

Feb 8, 2012

I need to read data from an Excel sheet as part of a data conversion. Certain columns contain mostly numeric data but may contain some alphanumeric data somewhere in the excel sheet. The problem is, my conversion sees the alphanumeric values as null (or blank. Using the .ToString() method returns ""). To connect to Excel, I'm creating an oledb connection, creating an OleDbDataAdapter, then filling a DataSet with the adapter.

Here's the VB code for connecting:
private _oleadpt As OleDbDataAdapter
private _oleconnection As New OleDbConnection
Dim olecomm As OleDbCommand
'_database comes from a settings file and is the full path to an excel document
Dim connstring As String = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & _database & ";
Extended Properties=""Excel 8.0;HDR=YES;"""
[Code] .....

I think the data adapter is determining the datatype for the columns based on the first however-many rows it looks at. It decides the columns with numbers are numeric which is the start of my problem. Changing the formatting of the column in Excel doesn't seem to affect the datatypes in my data set. Is there a way to tell the dataadapter or dataset what type of data to use for a column? Or should I try to cast the data in my SQL statement?

Possible To Fill A Collection-Type Instead Of A DataTable/DataSet?

Aug 4, 2010

this 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()

Setting A DataSet Row Value To Nothing Initialize It To The Data Type Minvalue?

Dec 2, 2010

When setting a DataSet row column to Nothing, like row.Date = Nothing, why does it initialize it to the data type minvalue? In this case a date, that gets set to 0000-01-01. The column is set to allow null etc., and if I don't set the row to anything at all, it will leave the column empty. So why does Nothing act this way?

In C# I would've set it to DbNull, I guess, but I'm a tad green on VB.NET - as you might be able to tell. :)

C# - Serializing A Dataset To A Strongly Type Business Object Property?

Nov 14, 2009

In a vb .net winforms app I am trying out something for "wide and shallow" children of a record. I use strongly typed business objects ( Strataframe ).My plan is to have a number of "child tables" collected in a dataset I drop on the form. they have no correspondence in persisted data, so the dataset is untyped and I am creating the schema through the property sheet for the tables. Each table is the datasource for a datagridview in the interface.

In my proof of concept sample, My main businessobject (CustomerBO) interacts with a SQL Server 2008 table with fields - pk, name, - and a third column which is currently varchar(max) as I considered XML but could just as easily be varbinary(max) if that works better for holding the serialized dataset.

bo.bigfield will be the strongly typed prop I want to hold the byte() array or XML or whatever that represents the dataset for that record.So, the question in a nutshell - how do I convert a dataset to a single datum and reproduce the dataset from that datum. This is my first foray into datasets, datagridviews as well so if there are better ways to accomplish any of that I'm listening.

OleDbDataAdapter To An Access 2007 Table / Generate Dataset Type Not Defined

Dec 9, 2010

I've create a new VS 2008 Window Form Project using VB. I added an oleDbDataAdapter to the first and only form, set it to a table in my Access 2007 Database (there is only one table, PK field autonum of course and two Memo fields). The Database is in the Project's folder. A standard oleDb Connection object was created, as I expected, then I select the DataAdapter and choose 'Generate Dataset' which produces a standard DataSet called 'DataSet1.xsd'. Now when I build the project I get an error 'Error 1 Type 'FontTest.DataSet1' is not defined.' I do have a reference in my new Project to System.Data.So what the @#%$@ is going on? Why isn't the Dataset create by the DataAdapter being recongized? I can get into the DataSet Designer. The DataTable create is perfect, three columns defined correctly as I expected.

Method Which Check If A Certain DSN Exists Then If It Does Extract Information And Use Information For Connection Purposes

Feb 2, 2011

I was looking for some stuff online, and i was looking through my reference sheets for vb.net, but it seems in the code i have found, there is declare in methods. Below is an example i am talking about. The thing is, that i dont recognize it and believe that it is an earlier version of Visual Basic ( 6 or earlier) which used it. Should i just keep looking for different code?

Public Declare Function RegOpenKey Lib "advapi32.dll" Alias "RegOpenKeyA" (ByVal hKey As Long, ByVal _
lpSubKey As String, phkResult As Long) As Long

Goal: Find information on how to implement a method which will check if a certain DSN exists, and then if it does, extract the information and use the information for connection purposes.

VB 2008 Dataset Error : "A First Chance Exception Of Type 'System.InvalidOperationException' Occurred In System.Data.dll"

Sep 27, 2008

I am trying to perform a simple bound connection between an Access database and a text box on a form. This is actually Chapter 18 of the "Microsoft Visual Basic 2008" book.I get the same error message when trying to create my own project "MY ADO Form" or the "ADO Form" project supplied from the DVD provided with the book. I am running the 90 Day Trial Version of Visual Studio 2008 with SP1 and Net 3.5 SP1.

My operating system is the 64 bit Version of Vista with all updates.The error when I try to run the application in the debug mode is:"A first chance exception of type 'System.InvalidOperationException' occurred in System.Data.dll"and as a result no data shows up in the text box from the database and the data selection bar is grayed out in the form. The underlying database "Students Data Set" appears to be fine as I have seen the correct data for the fields "Instructor" and "PhoneNumber" prior to running the program and when connecting with the database.

In a VB.NET Windows form, I have a form named "form" I got this error in the form.Designer.vb whenever I assignt a data bound to a control. It complains in the "Designer" that "Type 'namespace.dataset' is not defined". The dataset is attached to the form in the design mode when I assign a data bound to a control to the Windows form and it generated the code to the "Designer" page. I can go to the "Designer" page to remove the "namespace" of the dataset and the error disappear. However the namespave re-appear to the dataset in the "Designer" page once I open the Windows form in the design mode.
