i've used the same commands several times and even tried copying the code from another project and importing that table and still get the same error. am i missing a namespace or class or something?

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.

VS 2010 [RESOLVED] UPDATE table SET( syntax error
View 3 RepliesI 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'm trying to updatesome records, currently my table is blank apart from the user id which is correct. but i get the error below.

I have this code to edit the datarow of my table adapter but t doesnt update the table. I think i have a missing code that's why but i cant figured it out. by the way im using vb2008 and SQL as my database. [code]
View 3 RepliesI 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!
An unhandled exception of type 'System.InvalidOperationException' occurred in system.windows.forms.dllerror in line: dbAdp.Update(dbDset) in btnSave_Click, (elseif editflag = true) blockdescription: Update unable to find TableMapping['Table'] or DataTable 'Table'I was also wondering if I could simply use the ExecuteNonQuery for the delete statement, but since I've placed my data in a datarow, I'm not sure if i can actually use it. Any thoughts on this? Btw, this is my first time using a datarow, and I've recently been studying how to use ADO.net.

I am having two tables with a similar structure. I want a code to select data from one table and update the same in second table and then delete the records in the first table.
View 6 RepliesI need to Update Access Database Table with Data from a Different Table. Not all the rows of original Table to be Updated will be affected. How do you loop through the 2 Tables to do the required Update.
The Table to be updated is called "RecordList" and Table with new Data is called "RecListReport".Every attempt I've made won't work. I tried to Use 2 Datagridviews but couldn't get it to work right.

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.

in my every form i use update button to update values in a raw,
Now my query is that:- for doing so right now i have two option
1) UPDATE Table1 SET Column1 = Value1, Column2 = Value2 WHERE Some_Column = Some_Value but in this if i have many colom it will be a long process as in some table i have more than 50 coloms.
so i found a second option which is, first delete the row and then again insert the values but in this case it changes its row no which in some case not good for my project.
so i want to know is there any way to update * . or is there any short way to update similar to delete and insert.

The above code is how I call the three tbls, the weird thing is that if I switch the order (savings with expenditure) then savings will be allowed to get updated and not expenditure.
