Why is my bulk copy duplicating each row, so in my database table the row shows twice.
Label1.Visible = True
Dim tourid As New List(Of String)
tourid.Add(TextBox1.Text)

I am working on a desktop application in VB.Net (4.0) There will a lot of SQL scripts which contains a lot of insert queries Currenlty we are running the scripts using SMO (http://msdn.microsoft.com/en-us/library/ms162557.aspx)For performance, we have planned to change the sql scripts to xml file ( instead of insert queries, it will have xml data with a proper xsd defined )Loads xml to dataSet and Using SQL Bulk Copy we are trying to insert to SQL Server.
[Code]...
Now i got it to work but the bulk copy is inserting the rows twice, instead of once and i know the table has the correct rows because i can see it in the gridview correctly I FIXED THIS PART my program works fine when i run it in debug mode but not when i place it on the server, it doesnt run the stored procedure when i put it on my server.
Label1.Visible = True
Dim tourid As New List(Of String)
tourid.Add(TextBox1.Text)
Dim tasktype As New List(Of String)

I'm using sqlbulkcopy to load data into a sql2008 database, and we're getting timeout errors loading larger tables. Some tables which were loading OK are failing since indexes have been added to them. The source data is a Informix datareader. I've tried setting large values in both the connection timeout and the sqlbulkcopy.bulkcopytimeout, but the timeout usually occurs within 60 seconds, well below the timeout values I've set (240 secs). I've tried setting the .bulcopytimeout property to zero but it makes no difference. Very occasionally a load will take place - the last large table to load took 7 minutes. I've reduced the batch size to 500.
The documentation on bulkcopytimeout that I have found does not describe what the property actually means - is it the maximum time to complete the entire copy or to complete one batch or what ?Here's some extracts from my error log - the first shows a successful large table load, follow by timeout failures.

I am trying to achieve the following. I have a web page that I want users to upload a .csv file to, that places the file on a local server and then after that the file is then bulk inserted to a sql database. I can't get the file to save in the location mentioned in the script and I would like to do the bulk insert cleaner.
I am using filesystemwatcher and im watching printer spool activities:
Private Sub fsw_Changed(ByVal sender As Object, ByVal e As System.IO.FileSystemEventArgs) Handles fsw.Changed
copyfile????
End Sub
But, while printers status is spooling the files and size also changing, how can I copy file bytes by bytes?
Something like this:
Dim a As ByteDim b As ArrayList
Private Sub fsw_Changed(ByVal sender As Object, ByVal e As System.IO.FileSystemEventArgs) Handles fsw.Changed
'+++++++++++++++++++++++++++++++++
get all new bytes and added to arraylist
After the arraylist gathered all bytes, I want to copy back to its original state of files to other location....

frmAddUser is a simple form that is opened as a dialog by a command button on the primary form (frmPrimary). Once opened, it's only job is to collect information via textbox and combobox fields. Once submitted, the information is added to the database.
This works, or so I thought. If I open this form, fill it out, and submit the information; the record is created. However, if I turn around and do it all again with different information, another record is created but with the previous information (not the new). It will continue to make records as long as I keep submitted this form but no matter what information I put in, it always uses the original information that was used to create the first record.[code]...
This works like a charm... loading DropDownList2 with all the items from DropDownList1 without looping:
DropDownList2.DataSource = DropDownList1.Items;
DropDownList2.DataBind();
But, the data from the item text of DropDownList1 is copied into both the text and value fields of DropDownList2. Is there anyway to get both the text and the value fields to populate properly?
The "Details" fields keeps repeating itself for example its showing it 4 times instead of one!this is my code[code...]
View 7 RepliesI want to start a new development thread so I can maintain two versions of a solution. I set up a new directory next to the old and copied the contents of the existing directories into the new. That's all well and good but now I can't update references in the new project to the new directories. I remove a .DLL and when I add it again, it keeps including the .DLL from the old path.
I'm running VS2005 and the solution is made up of 5 or 6 different projects (if that makes a difference.)

I have a form where i can enter new product. In that same form i have listbox where i show the current product from the database.
I want to know how to update that listbox as i enter new product into the database so that user can see the current content of the product table.
my code to load the listbox
Try
Dim ds As New DataSet
Dim cmd As New OleDbCommand
[Code].....
To sum it up, what i want is something that will refresh the current display of the listbox so user can see the actual and updated contents of the database.
with the above code, the newly entered product/data can only be seen when the program is closed and reopened again. Which is not very convenient.
