have a MS access table and I want to export it to comma delimited
text file. How do I do this programmatically using VB.NET or C#?

Thanks for any help in advance.

Hi,

For exporting Access table data, you need to read the records in
DataReader and then write these records in .CSV file one by one....

You need to follow these steps:

1. Open the file for writing (in append mode) with file stream writer:
Dim sw As New StreamWriter("FileName.csv", True)

2. Read table in DataReader.

3. Loop throught the data reader, Read record in string variable, Write
in File.

Dim strRecord as string

Do While myReader.Read()
' Use ',' (comma) as seperator when you are writing field values in
file.
strRecord = myReader("FIELD1") & "," & myReader("FIELD2") & ","
& myReader("FIELD2")......

' Write record in file.
sw.WriteLine(strRecord )
Loop

I don't know if there is some other way to do this.

You can do this rather easily with ADO.NET and SQL:

Dim AccessConn As New System.Data.OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;"
& _
"Data Source=e:\My Documents\db1.mdb")

AccessConn.Open()

Dim AccessCommand As New System.Data.OleDb.OleDbCommand("SELECT * INTO
[Text;HDR=No;DATABASE=e:\My Documents\TextFiles].[td.txt] FROM Table_3", AccessConn)

AccessCommand.ExecuteNonQuery()
AccessConn.Close()

wow. I am blown away.

Does that require Access to be on the machine? I've always been under
the assumption that the brackets were only available from within
MSACCESS.exe

I'm blown away as well, that's a pretty cool solution.

The one thing I feel like a complete idiot asking is the default file
export format is always CSV delimited, and I'd like my export to be a
TAB delimited text file. I've tried a zillion keywords to do this, all
with no luck. No help from google yet.

Could someone please let me know what I need to change in

SELECT * INTO
[Text;HDR=No;DATABASE=e:\My Documents\TextFiles].[td.txt] FROM Table_3

to generate the export in a TAB delimited format?

Thanks in advance.
