.net SqlBulkCopy With Unicode Chars

Nov 29, 2010

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.

.net - Regex Replacing Non-words Chars In Strings, Ignoring Specific Chars?

Oct 8, 2011

In VB.net I've got the following line that removes all non-alphanumeric chars from a string:

return Regex.Replace(build, "[W]", "")

I now need to extend this to remove non-alphanumeric chars that aren't [] or _. I've changed the line to:

return Regex.Replace(build, "[W[]_]", "")

However I'm pretty sure that this says

replace non-word or [ or ] or _

how do I negate the tests for the [] and _ chars so that it says

replace non-word and not [ and not ] and not _

Some examples:

"[Foo Bar_123456]" => "[FooBar_123456]"
"[Foo Bar_123-456*]" => "[FooBar_123456]"

SqlBulkCopy From CSV To SQL Datatable?

May 24, 2010

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.

Importing Data Using SQLBulkCopy?

May 25, 2012

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()

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"

VS 2005 Dataset, SQLBulkCopy Update Table?

Apr 25, 2009

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.

Well my question is simple and straightforward. Is there any way we can use hex values like in c++?

I am going to write binary files, but for that i will have to define certain characters like this for example.

Strip Bad Chars From Excel Cell

Jan 5, 2011

I am trying to evaluate cells in Excel for invalid chars (I use them as lookups). They come from other sites so I need to quickly strip out bad chars (high ascii). I wrote a simple function that tries to loop through the positions of a cell starting from the end until it gets to the begining. It looks for the first ASCII char between 48 (ASCII for number 0) and 122 (lower case z). Everything else it would discard as junk and continue looping until it gets a good character. This will be the rightmost char to include so I could use a left(string, index) to extract valid data from a cell.

VS 2010 Reading Chars From A String?

Nov 11, 2011

still pretty new to programming in general, but I have most of the basics figured out.I stumbled across this problem today, though. I wanted to try making a simple encoder/decoder. However, I am having trouble getting characters from a string.

I have a list(of char) to separate the individual letters in the message (letterList), and textToConvert is the text that the user types in to be encoded. Here's the section of code my problem exists in:

For i = 0 To textToConvert.Length - 1
letterList(i) = textToConvert.Chars(i)
Next i

Upon running my program, I get an out of range exception for the middle line above. Am I doing something wrong?
