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.

Why is my bulk copy duplicating each row, so in my database table the row shows twice.

When I load images using openfiledialog I need to store a backup copy of the images to the other folder using the same filename and with the same extension.So how do i do that as in the below mentioned code I am able to copy only one image and I have given random string for that image.But I don't need that.I want to copy with the same filename and with the same extension.And if I have the same filename it should overwrite it but not with a different name and extension.[code]

View 10 RepliesI posted earlier this week about reading in data from a csv/txt file into an array. My data is huge, 100 columns and 12000+ rows. I would like to name variables by column and then plot these variables. After I read the data line by line and delimit the row, I'm not sure how to put each integer into it's own separate column, and then continue this for the next row and the next row, ect.
After some reading I would imagine the proper way to do this would be by creating a structure and then read the data into the structure, but there's no real starter example/tutorial out there that does this. I know some people will read this and get pissy, but you've got to realize I'm coming from Matlab and vb.net is a huge change for me.
I am working on a program where I need a small database. I wanted to use XML to store the data, so I followed this tutorial:Everything there works fine. What I now want to do is figure out how to execute SQL statements against the imported data to do inserts and queries.I've searched and searched, but cannot seem to find relevant info. Every example I see needs a connection string, but that doesn't apply here as far as I can tell.

Is there a way to transfer huge amount of data in a single shot from vb.net to Oracle database? I have a couple of thousands of records in my vb.net code which I want to update to Oracle database. What I do currently is, call a stored procedure in database once for each of those records. This would end up calling the stored proc couple of thousand times, which is highly inefficient.

Another noob question from me...one of these days I'll get the hang of this VB!I am importing data from an Access table that has four columns/fields. I have set up the relevant headings etc on the list view control...but I have also set up a 5th column as I want to have that representing the percentage change between columns 3 and 4 (which are numeric).
Here's my code. What I want to know, is that having confused myself with code I've written / adapted from advice given etc where do I put in a forumula to add something to a column in my list view that is a calculation based on two columns imported from the table?

I am importing data from CSV file into a dataset using OLEDB data adaptor.I created a query with query builder to extract the desired data then copied the text generated into my code. Everything works as it should exepct that the seconds part of a datetime column is missing when the code is run.The odd thing about this is that the seconds part appears when i execute the query in query builder.[code]

View 2 RepliesI have a VB.NET application that creates a dataview from sql table and exports it as an excel file. Now, the data is inserted value by value. Instead, I want to insert the data from the dataview as a bulk insert on to the excel file. The data insert should happen from the third row, as I need to use the first two rows for column insert and data formating (which is done later in the program using excel macro.).Heres the code I wish to upgrade :
Dim strConn As String = "Data Source = LV-SQL2; Initial Catalog = TC_MASTER; user id = SQL2JOB; password = ******** "
Dim strSql1 As String = "Select Customer_id_1, file_name from customer_list_DA order by customer_id_1"
Dim da1 As New SqlDataAdapter(strSql1, strConn)

How can I copy a datagridview to a gridview.. I only ask b/c I need to use the rendercontrol and its not available using datagridview. And Gridview is not an option for me to use in a windows application.. BUT the class is.. very odd but anyway. All the colors formatting etc.. I need to pass to the gridview.
View 2 RepliesI have a datagridview and I would like to be able to select an entire row by clicking on the row header column, hit CTRL+C, then put the cursor in the next row, and hit CTRL+V to paste the contents.
Right now, it pastes all of the contents into the first cell of the new row. If I paste the contents to the clipboard, I see them correctly and they are tab delimited.
Once I get this working. I would like to be able to copy and past multiple rows at a time.
FYI, I am not using a data source at all. Most of the rows are combo boxes where a user is selecting values. There is no database connection.
I have an app where in some of the DataGridViews I am able to easily highlight a segment of text within a cell, do a Ctrl-C, and then paste it into some other app. Only the highlighted text gets copied, which is what I expect.
However, with some of the DataGridViews, I try to do the same thing, but it will copy all of the cell's text, not just the portion highlighted.
I've scoured the cell, column and DataGridView properties and can't figure out what controls that ability.
How do I disable copy from a DataGridView. It's a silly security feature.
