SqlParameterCollection.Add doesn't have a prototype that takes a String, SqlDbType, and String.

http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlparametercollection.aspx[^]

It may be trying to convert the string to an integer which is where you are getting your problem. If you want to use the "SourceColumn" of the add, you also need to use the prototype that specifies the column size.

Instead of writing:

VB

.Add("@id", SqlDbType.BigInt, "id")

you need to write this:

VB

.Add("@id", SqlDbType.BigInt)

And then you assign the values to the parameters:

VB

cmd.Parameters("@id").Value = id

There is no overload with a string as a third parameter. Use:
.Add("@ApplicationDate", SqlDbType.DateTime)

I guess you have implemented the syntax of DataAdapter Parameters[^], but you need the syntax for SqlClient.SqlCommand as you have done like this.

VB

Dim cmd As New SqlClient.SqlCommand("Populatecsv", con)

So, refer - Configuring Parameters and Parameter Data Types[^], which has the best example how to do it using SqlClient.SqlCommand.

The third parameter in the Add method is not a value. It is a size for the string values
