query timeout expired

Using VB, I am running a bulk insert query from csv file into a newly created table. It works fine on small test files; but when I try it on the production data, I get a "query timeout expired" message and processing ends. The text files contain several hundred thousand lines.

How can I resolve this problem. I have several hundred of these csv files and more coming.

Here's the code:

Dim sSQL As String
sSQL = "BULK INSERT " & TableName & " "
sSQL = sSQL & "FROM '" & DataPath & "' WITH "
sSQL = sSQL & "(FIELDTERMINATOR = ',', ROWTERMINATOR = '\n', FIRSTROW = 2)"

DbConn.Execute sSQL
