Sql - Table Adaptor Error When Trying Update?
Jan 17, 2011
I have a rather perplexing issue. I am using VB.net and SQL for my project.I have a database, to which the connection works. I also have a data table and data adaptor, both of which I know work.I am trying to update something in the database, yet it isn't working. Assume everything listed is declared correctly. What am I doing wrong?
teacher_control_table.Rows(0)("DATA_TeacherLockPasscode") = txtPasscode1.Text
table_adaptor2.Update(teacher_control_table)
That last line throws the following exception:
InvalidOperationException was unhandled. update requires a valid UpdateCommand when passed DataRow collection with modified rows.

I have a table adaptor that pulls from the sql database, when I edit the table adaptor query it makes this specific table adaptor not a part of the dataset. I have added a column to my database which will contain an integer, when I try to add this column to the query this error occurs, i am using the configure area of the table adaptor.
Error 'AuditProductsTableAdapter' is not a member of 'MemKingClient.MemKingDataSetTableAdapters.TableAdapterManager'.

Rather than running numerous queries in Access I am trying to write a front end for a DB2 database. The Access database is getting to a size that it is causing Access 2007 to have reliability issues and frequent compacting is required. I have created the Dataset, the Table Adaptors, and the Connection String already, but when I put in a bit of code in to fill the Table Adaptors the remote connection I have to work is going crazy (chewed up about 180MB before I realised it was pulling data from work).
Before I started the project I copied the .accdb to my local PC HDD and I pointed the connection string to it, but it still looks like it is trying to pull data from the work network. If it was a small database I wouldnt be concerned but it is pulling major data every time I run it. I have only 2 out of the 4 Table Adaptors running and it didnt fill them even after 10 minutes.
Here is the code I was trying to run... Server name has been substituted for Server for obvious work reasons.
Because the tables are so large I was looking for a way to pull only the columns I need to from the tables, I tried adding .SOFT_ID to the first line of code but the TA spat the dummy message below...
Value of type 'System.Data.DataColumn' cannot be converted to Application_Name.DS_DB2Database.Server_SOFTDataTable'.
Code:
Me.TA_ServerSOFT.Fill(Me.DS_DB2Database.ServerSOFT.SOFT_ID)
Me.TA_ServerSOFT_FOUND.Fill(Me.DS_DB2Database.ServerSOFT_FOUND)
Me.TA_ServerHARD.Fill(Me.DS_DB2Database.ServerHARD)
Me.TA_ServerREF_SUP.Fill(Me.DS_DB2Database.ServerREF_SUP)
I would also like to pull just the data columns I need to speed up the query.
Note: In case youre wondering why I am not connecting directly to the DB2 database. I currently dont know where it is stored and while leveraging Access I am trying to put a level of separation between the app and the db for the time being, later I will try connect directly.

I am working on a simple programme that has a dataset linked combobox that changes the contents of a datagridview when the SelectedIndexChanged event on the combobox occurs. (i.e. you select a client in the combobox and it shows you all of the orders they have placed in the datagrid view). I have got the two set up and displaying the data but cant get it to update back to the database when I add a record to the datagrid view.
Here is my
Imports System.Data.OleDb
Public Class Form1
Dim cs As New OleDbConnection("Provider= microsoft.jet.oledb.4.0; data source=C:VB
wind
wind.mdb")
Dim ds As New DataSet
[Code] .....
Is it because the second data adaptor uses a variable in its sql string which only shows the current record of the combobox? If so how do I get around this and update the records added to the datagrid?

I am using VB.NET 2010 (Visual Basic 2010 Express) on a WPF-based project. I am also using the SQL Server Express built-in to Visual Basic 2010 express.I have just about finished refining my code for hooking up my wpf-based form to an existing SQL database (agentroster.sdf). I have a global data source (AGENT_ROSTER) connected to this database. Connections are confirmed to work properly.This is the first part of the code I'm using, irrelevant code omitted,
Dim table_adaptor As New AGENT_ROSTERTableAdaptors.AGENT_ROSTERTableAdaptor
Dim roster_table As New DataTable("roster_table")
Dim rowposition As Integer
[code]....
how do I fill roster_table with table_adaptor (or alternate method)?

I keep getting the error shown in the screenshot below.To me it's saying that I haven't established the "UpdateCommand" property for the DataAdapter. However,I have established it as well as the "SelectCommand", "InsertCommand" and "DeleteCommand".All of these are created within a Class Module.I created a Class for the "tblControl" table that is is referencing. This class contains all the properties for this table as well as calls for "inserting", "updating", "selecting" and "deleting" records.I have attached a class.vb file so their is a clearer understanding. The highlighted line of code below is where I'm receiving this error message.[code].....
I'm receiving this message while trying to add a NEW client record as well as a NEW client Address record to the database. This portion works fine. I get the error message when I try to UPDATE the tblControl table with the new ClientID. The below code is where I do the inserts and update.By the way, I actually execute the "control.ControlOleDbCommands()", which establishes the adpControl DataAdapter Commands, when the program starts.[code].....

I have a project which contains a large number of lookup tables, and I have all of these lookup tables represented in a single typed DataSet, which contains TableAdapters for each lookup. I've designed an editor for these lookup tables, which should allow editing of one of these at a time. My front-end is written in VB and WinForms, the back-end is a SOAP web service; I can successfully pass the changes to the DataSet back to the web service, but can't find a way to use a TableAdapter to update the single table that has been changed.
What I'm trying to do is instantiate the appropriate TableAdapter for the updated DataTable by sending the name of the table back to the web service along with the DataSet, then referring to the TableAdapter with a dynamic name. The normal way to instantiate a TableAdapter is this:
Dim ta As New dsLookupsTableAdapters.tlkpMyTableTableAdapter
What I'd like to do is this, but of course it doesn't work:
strTableName = "tlkpMyTable"
Dim ta As New dsLookupsTableAdapters(strTableName & "TableAdapter")
Is there any way to achieve this, or am I taking the wrong approach altogether? My other alternative is to write separate code for each table, which I'd prefer to avoid!

Any thoughts on this? Btw, this is my first time using a datarow, and I've recently been studying how to use ADO.net.

How can I update local dataset with mysql database without making duplicates. Assuming I set some column in mysql as primary key, which has unique string.
adapter.fill will just add duplicates, but adapter.clear before that is not an option.
So I want to update if the key column is the same with mysql data and if there is option for ignore adding new row.

I have written a sketch for Arduino that sends serial data to my VB.Net app. Works great using the included USB port on the board. I need more distance, so I installed a MAX232. This is interesting. I get proper data in TeraTerm for both com ports (the Arduino USB comes up as a com port). I get proper data in my VB app from the Arduino USB (com) port. I get nothing from the MAX232 circuit on the other com port in my VB app. Why would both work in TeraTerm, but only the USB cable on the Arduino, not my MAX232 circuit in my application?

I have a form with comboboxes, if the user doesnt select a value in the box I want a null to be sent to the database. The insert works fine, i look at the record in the db and see the null. The update doesnt work. gives me a n "Update statement conflicted with foreign key constaint....."
Public Sub Update()
TableAdapterCreate().Update(ID1, ID2, CType(cbox1.SelectedValue, Integer), CType(cbox2.SelectedValue, Integer), CType(cbox3.SelectedValue, Integer), CType(cbox4.SelectedValue, Integer),
[CODE]...
As I step through the selected value of the cbox 5 is shown as nothing (which it should be because the user didnt select a value for this combobox). I assume this needs to be a null instead of nothing to get written to the database. the combox boxes need to match a primary key in another table so sending a 0 would also result in the forieign key error since the related table does not have a 0 ID field.
