.net Updating Oracle Record ExecuteNonQuery?
Mar 17, 2011
when i use TOAD to update a table all works just fine when using this query:
Update CSR.CSR_EAI_SOURCE ces
Set (STATUS_CODE, COMPLETE_DATE, DATA) =
(SELECT 'ERROR', '', REPLACE(REPLACE(c.Data, '...', ' '), ''','''')
[code]....
It stays on the ra = OracleCommand.ExecuteNonQuery() continuously until i get the error The CLR has been unable to transition from COM context 0x3327fa8 to COM context 0x3328118 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time. To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during long running operations.What could i do in order to get this working within VB.net since it works just fine in TOAD when running that same query?

I'm testing my program, which uses an access database, and it works just fine on:
Windows XP with .Net Framework 2.0 sp2
Windows XP with .Net Framework 3.0 sp2
Windows XP with .Net Framework 3.5 sp1
But in Windows 7 with .Net Framework 3.5.1 I'm getting an error in the ExecuteNonQuery() line when updating a record in the database.
The code I use is:
Dim con As OleDbConnection
Dim cmd As OleDbCommand
Dim cGebruiker, cWachtwoord As String

I'm using parameters on a SQL stored procedure to insert a record with data entered on a website form (and on the form I'm using VB.net). As of right now, the form works perfectly; the record is inserted. However, after the user hits the submit button, everything executes and then the page will basically refresh with emtpy values in all the fields. So I want to give the user some type of SUCCESS message, assuring the user the information was successfully entered into the database. So my question is: How can I verify that the record insertion was successful? I want to do this with the ExecuteNonQuery statement, because that's what I'm using.
Code is below:
If Page.IsValid then
Dim MyConn as SQLConnection= New SQLConnection("Blah")
Dim MySQL As SQLCommand
MySQL= New SqlCommand("proc_newWebEntry", MyConn)
MySQL.CommandType = CommandType.StoredProcedure

Essentially this section assigns a randomly generated password to a user if they have forgotten theirs. The password is generated in some other code.
I have set up the SQL to search for the log-in details (in the case and email address which is unique), it then brings in the field and then updates it to the new password.
But for some reason I cannot get it to update the MS Access Table.
I Keep getting a SYNTAX Error message.
Private Sub bthresendpassword_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles bthresendpassword.Click
If txtemailaddress.Text = "" Then

Visual basic 2010. I am having a problem with updating on a DataGridView that has me confused.
I have a DataGridView on the first tab page that is displaying data in a DataTable.
On the second tab I am updating the current record on the DataGridView.
The text fields on the second tab are bound to the DataTable in the following manner
rnameTxt.DataBindings.Add(New Binding("Text", TableData, "rname", True))
When I move to the second tab the correct data appears in the text fields.
When I modify a field on the second tab the modified data appears in the DataGridView, on the first tab page. But when I check for changes in the DataTable in the following manner
Dim ModifiedRows As DataTable = TableData.GetChanges() I do not see the modified row - i.e. ModifiedRows = Nothing? Why is the modification not being identified???

OK - I have worded this search 40 different ways and I seem to be lost here. Every example I find seems so happy that you can easily drag and drop a datagrid and let the user fill it in -- then they stop! I know how to do everything I am asking through LINQ. That obviously won't translate here. I really should have learned ADO.NET first, then LINQ, but NOoooo... I need to know how to do the following in .NETCF (Windows Mobile 5) using a SQL CE database on the device.
Add a new record and populate some or all of the fields with data I supply. I don't need to add a record to a datagrid - sometimes the user will not even see the record. How do I add a new record -- put data into it and save it? For example: Create a new delivery record, say, and have the program store the date in one field and a number in another field. Search for a record, then update data in it. Again, using LINQ I can do this easily -- I cannot for the life of me find any examples of doing it without it.
I can find lots of examples of populating a grid of databound fields, letting the user make changes then saving it out. I don't need to do that. Say I need to search for the one record that meets a criteria (customerID=10 and orderID=1234), then when (if) that record is found, update a field in it.

I can't seem to save data in the database when updating a record. The record appears to be updated and even displays the new record on my form but as soon as I close and restart the program the old record is back and no changes are made to the database. Is there something im missing here ?
If CN2.State = ConnectionState.Open Then
Dim Comand As New SqlCeCommand("SELECT * From Incentives Where IncentiveCode = '" & TxtCode.Text & "'", CN2)

This is the form I'm having problems with. As you can see I've created a tab interface which is working. There are five text boxes on it which are binded to the Staff table in the database. When the tab is changed, the binding is changed to a new field. However, unfortunately, when a new record is selected, the data bindings do not update, and instead, the first record is always being used. We suspect the problem may be coming from the fact that there is code to unbind from the text box and rebind it again. This is the code I'm talking about...
Private Sub TabCheck()
If TabState = 1 Then
pnlTabs.BackgroundImage = My.Resources.tabs1
txtBox1.Visible = True
txtBox2.Visible = True

On my form I have a datagridview which is bound to a 'Supplier' table in Access 2003. Once I click on a record on the DataGridView, textboxes below which are also bound to the same source are automatically populated with the relevant data. What I want is when I click update, that the records in the database are updated as well as the dataset but what happens is that the dataset is updated, I invoke the tableadapater.update method but no permanent changes are made to the database.
Below is the code attached to the 'Edit Supplier' command button.
Private Sub cmdEditSupplier_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdEditSupplier.Click
Me.SupplierTableAdapter.Update(QuoteDataSet.Supplier)

Scenario: VB2010 express + Sql Server 2008 express.
I have a master/detail form where I can modify a record. With VB 2010, I use the new Table Adapter Manager which handles all Updates/Deletes against the database inside a Transaction. Question is that before I update the modified record (only the master one), I need to insert it in another table (history table). My question is how I make both insert and update inside the same Transaction. By code? Using Stored Procedure?

I am trying to update an Oracle Database record and i keep getting this error:
ORA-01704: string literal too long 5
I looked up that error and it seems that i have a limit of 4000 charters since i am using Oracle 10g. However, the prgblem is that its the same exact data i am putting back into that record so that is why i am unsure as to why its giving me that error for the same amount of data i took out of it.
Here is my update code:

there is a tab control system. It relies on only five text boxes, and their bindings change when the tab is changed The relevant information is displayed. However, if I navigate to a different record...You can see that the same information is displayed in the tab control text boxes, and not the employee's details I just selected in the data grid or the navigation. How can I fix this? I'm not sure what's gone wrong here. Here's the code that changes the text boxes upon changing tab...
