Verify Record Insertion Using ExecuteNonQuery?
Jan 2, 2007
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

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

Been looking at this for a few hours now, is it possible to insert into the FIRST line in a rich text box? I have a simple app that regularly copies a reference file to several PCs but I need to have the success/failure and timestamp visible, so I want to insert into the top line each time - ie. in descending order.

Im confused on how to write a code on checking duplicates before insertion on vb.net. I know the sequence on how to do it but its kinda confusing when writing a code.
1.) Create a query that will check if the mobile number already exists on the database
2.) If not, insert the new data
3.) Else, a message will prompt that "You are already registered".
writing this in PHP is kinda easy for me but in vb.net.. , unfortunately, not easy.. Im still a beginner on vb.net.

I've been trying to learn enough to develop the family tree diagram and making progress.[URL]..It illustrates many of the drawing, saving, re-opening, editing, drag/drop features that the family tree diagram would need, and is a good starting point.
To adapt this for the project, after searching for snippets online, I've tried to add dynamic insertion of a label as a start (eventually, it should be a textbox that the user, in runtime, can enter text into, save, re-open, edit). But, I can't get this to work. No errors display, but I must be doing something wrong.
Here's the label code which I've so far appended at the end:

I know you can do it with an WMI event or overriding WndProc and looking for the right messages, but i was wondering if there wasn't something hidden in the net framework that makes this task easyer.

I have recently been working on a number of sections of code that deal with the insertion of Nullable types into a database. As I'm sure anyone who has dealt with similar code will be aware of the annoyance of constantly writing conditional logic to deal with the insertion of nulls into a database. I.e.:
MyValue.HasValue ? MyValue.Value : DBNull.Value;
If(MyValue.HasValue, MyValue.Value, DBNull.Value)
Basically I am just wondering why DBNull.Value exists and why Null simply couldn't be used?

Why is it that this VB.NET code only works for detecting flash disks?
Select Case m.WParam
Case WM_DEVICECHANGE_WPPARAMS.DBT_DEVICEARRIVAL
MsgBox("USB Inserted")[code].....
What would be the possible way to detect the insertion and removal of other USB peripherals, such as mouse and keyboard?

I am having problem with my FYP that my application is based on the detection of Insertion and Removal of a device. I am aware that this would happen using Win32_VolumeChangeEvent class or WMI. (Please notify me if I am wrong). Kindly solve this problem and send the code for Console Application in VB.NET. Please do not send code in any script language or C#. Also to get the device information.

scardgetstatuschange DOES wait(timeout is set INFINITE by -1) for card-insertion after connecting the reader-device to the pc. After a card is being insterted the first time and removed again, it won't wait any longer and returns immediately everytime;
lResult = SCardGetStatusChange(DethContext, -1, rgReaderState(0), 1)
So, scardgetstatuschange CAN work. But why only when i re-attach the cardreader-device to the pc????

Actually in our project we create different database using vb form code..so this database is a chance of transferring to other users to use others database. so when we create the database it will insert the database name into the main database. Problem: One user who is accessing MS 2010 ACCESS has created a database and transferred into other PC where MS 2003 access available..when he is going to insert database name into main database which is transferred it is not inserting into main database exception is occured..

I have dealt w/ SQL as back-end many times before, but this local CE database is driving me crazy. I have a dataset (CsDbDataSet) with my table (ServiceMonitor) all set up. I have the dataset configured for CRUD and everything looks just peachy there. The problem is that I cannot write directly to the table and have it show up. I don't get any kind of error, but when I run a SELECT statement on the table, I receive no data. Am I missing something?I am using the direct database access methods used herensert Method I am trying to use:
Dim ta As New CsDbDataSetTableAdapters.ServiceMonitorTableAdapter
ta.InsertRecord("Test", Now.ToString, "TestSvc", "TestSvcVer", "TestSvcStat", "TestNote", "TestProgram")

Update: (Please vote to close) This question is unresolved, and is likely a list view bug.It can be replicated by using the example code from the MSDN link below, and adding this code after the list view initialization code:
myListView.View = View.Details;
myListView.Columns.Add("Column1");
myListView.Groups.Add("group", "group");
