VS 2008 SqlBulkCopy From DataGridView?
Sep 7, 2010
I have a .csv file that is selected using the OpenFileDialog that then populates a ataGridView. The .csv file is then visible for the user to check a number of things. This part works fine.What I then need is once it is checked the user then needs to click a button to import this into my SQL Server table (CSV_Import). I have looked at SQLBulkCopy but am failing to get the data imported.Here is some code I have picked up and I am guessing that it is the bc.WriteToServer(dt) needs correcting within the brackets but I am at a loss at this point.
bc.BatchSize = dt.Rows.Count
bc.DestinationTableName = "CSV_Import"
bc.WriteToServer(dt)

I'm using SQL Server 2005, VB.NET 2005. I want to be able to import a very large excel file into a SQL table called "XYZ"
I've done this by doing the following:
1. Save the excel file as csv.(Using SaveAs XLCSV option)
2. Build a datatable "ABC" From CSV.(using ODBC Connection and Select * from '*'.csv command)
3. copy the datatable"ABC" into database table "xyz" (using sqlBulkCopy.WriteToServer())
It works fine without any error but when i checked my database i found that data type for some columns has been changed and hence it didn't copy some of the records.

i have a csv file that needs to be imported to sql server the file includes Unicode characters, so i saved it in notepad as Unicode now when i run this in sql it works excellent BULK INSERT personimps FROM 'C:MyImp.csv' WITH (FIELDTERMINATOR = ',',datafiletype='widechar')but when using the following in my code-behind in asp.net, i get gibberish where the Unicode chars should be. [code] it seems like the oledbconnection is ignoring the extended properties, or maybe i didn't set up the connection-string correctly? the ASCII chars come out OK, the Unicode fields are just gibberish.

We are getting the following error (only on the staging server) when we use SqlBulkCopy. The stored procedure has execute permissions. And they are working properly in our test environment. So what is the setting to be corrected in stage environment to work it properly?

We have a legacy application that is dumping large volumes of data to tab delimited files.Each file contains a single record type and all fields are fixed length.These files can readily be imported into corresponding tables in our SQL server database using the BCP utility from the command line.We have a VB.Net program written in VS 2003 that imports these files using the SQLDMO.BulkCopy routine. We are updating the system to use VS 2010 with SQL Server 2008 and according to the Microsoft documentation SQLDMO is no longer available.I have searched on the internet and have rewritten the import routine to import the tab delimited files into a DataTable using the Microsoft.Jet.OLEDB.4.0 provider. The SqlClient.BulkCopy object is then used to import this DataTable. This issue I am having is that fields in the tab delimited file that are set to spaces are being treating as NULLs when imported into the DataTable. When the DataTable is processed by the SqlClient.BulkCopy the copy fails because the null values are rejected by the SQL table fields that are defined as NOT NULL.Code being tested is shown below
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Dim data As DataTable = RetrieveSourceData()

I need to update a database table from a dataset and only have access to the database through an odbc connection. Is there anyway to make this work or do I need to go a different direction to do this ?

I am trying to sqlbulkcopy. I have a dataset defined (.xsd). It seems that I cannot use it with sqlbulkcopy. All the information I can find on sqlbulkcopy shows that it can only take a connection string or a variable that contains the connection string.

In a VB.NET, I code to exec a store procedre (sp_truncate) to truncate 10 tables and using sqlBulkCopy to download a huge data. Both them are working fine. Now I want to use transaction with vb.net (not in store procedure?) to rollback truncate tables if download is failed. Is it possible to use transaction to work with these two steps?

I used sqlbulkcopy to upload huge data from local to remote. It works great.The only problem is that there is a table tClaim in which there are 50 columns. One clumn "IsUpload" do not need to upload. How to upload all columns except for this column? If I use columnmappings, do I have to code add column one by one?

I was wondering if the following is possible. In a particular operation I want to create a dataset, bulk copy it to another SQL Server, then update a flag column in the copied rows.I'll have a system that will be regularly inserting new rows of data, then at regular intervals want to copy that data to another SQL Server. Once the rows have copied I need to change a flag column so that they won't get copied again.Whilst this is going on there is a strong possibility new rows of data will be being inserted into the source table. These new rows will be copied at another interval.

I have a DataGridView where Cell_Validating is being done. I have a Cancel button on my form that allows the user to exit out of the DataGridView changes. The problem is that if a cell was currently flagged as in error, I cannot exit and remove columns from the DataGridView. I get the following error: Operation did not succeed because the program cannot commit or quit a cell value change. Is there a way to cancel the validation once the focus has been removed from the DataGridView? Here is my Cell_Validating

I've built a reporting feature in my app that uses a DATAGRIDVIEW to show the results of a stored procedure execution.I've noticed that the datagridview has some nice features - like the user can re-order columns.And I allow them to re-run the report and the "re-execution" nicely fills in the DGV - even if the columns are moved around.Problem is that I also allow them to run different reports - and that column re-ordering and other "retention" features of the DGV are bad.Should I be creating a DGV in the IDE and then cloning that somehow at runtime for each report that is run. As long as they are re-running the same report then I can re-use the DGV like I am now.But if they select a different report then I dispose of the DGV and make a new one.

Below is the code to create a single Editable ComboBox column in a DataGridView on a form. I believe I have follwed the instructions to allow the user to input new values other than those in the list, however if you create a new project and add a button and a DataGridView control onto the form, then copy and paste this code and run the program, you will find that you cannot type any character in the edit box other then characters that exist in the list and only 1 character will be displayed at a time. I have set the Autocomplete value to 'False' and setting it to 'True' at least allows me to type more than 1 character but still not any strings that don't exist in the list.You can even remark out or not use the entire Call Validating sub routine to see the issue of not being able to type in the cell.

Making a comeback after five years, I am greatly impressed by the functionality of the DataGridView.It seems to me that the most obvious omissions are:
1) numeric columns, numeric up/down columns, date columns, list box columns;
2) printing a DataGridView;
3) binding a DataGridView to a database table when the database is selected at run-time. I see that several software houses offer products to complement the standard Microsoft DataGridView feature, all of them at a hefty price. I am satisfied with the RustemSoft product's DataGridView column features but it does not seem to offer any help with printing.Before I spend another $80 on DataGridView software, I would like to find out whether free coding is available for cut-and-paste or download. Maybe these features will be included in the next version of VB.NET but I cannot wait for that.

I am using VB.Net 2008 and have build a windows form with a datagridview that displays a query of records for the current client. One of the columns is for Fee. I need to total that column and place the result in a Label or Textbox. I am using the Query builder to pull the records and so I can not get away with the SQL expression in the query returns the Schema does not match error. I have tried to code it pulling the information directly into the form from the Datagridview and could not make that work either.

I just want to simply be able to edit a database directly using a Datagridview. That includes adding new rows, editing existing ones, and deleting rows. So far if I have been able to get one of those actions to work, the others do not. I found the codebank entry by JMC and I am trying to use it to connect to my database. I have a bindingsource, a dataset, and tableadapter created via the designer. Now I need to figure out how to combine all these components.
VB.NET
Imports System.Data.SqlClient
Public Class Form1
Private connection As New SqlConnection(My.Settings.Database1ConnectionString)
Private adapter As New SqlDataAdapter("SELECT ID, Name, Quantity, Unit FROM StockItem", connection)
Private table As New DataTable

I am trying to identify the value if a checkbox against a record in a datagrid.
I am trying this:
Dim eRow As Integer
eRow = dgv.CurrentRow.Index
TextBox1.Text = dgv.Item(6, eRow).Value
But I get nothing it works on other fields in the datagridview. The user will de-select records he does not want to authorise. When he has done this I want to update another table with the values that are selected(or True) on a button click event. There could be 100's of records so not sure if this is the best way to go about this.

Right now when I need to refer to a cell to update the text I do it this way:
DG1.Rows(intRow).Cells(1).Value = "Hello!"
Is there a way to use the column name for column #1 rather than the number? This way if I decide to add columns later in an update and it's not at the end of the current columns, I do not have to re-number all my code. I tried searching but must not be looking for the right keywords.

The code i have is like this:-

I haven't yet tried, but would the data append to the dgv if i just called this again using query and removing the queryTotal variable? seem to think they behave like that from past tests?

If I have a datagridview's datasource set as some datatable, is there a quick and easy way to reflect the changes in the datatable that have been made in the datagridview?
When I sort my datagridview, the rows in the datagridview and the datatable no longer match up.I know I can catch when the dgv is sorted and for-loop through the dgv and send it to the datatable, but I was hoping there was a save/update method or some such thing.
