------解决方案--------------------
试试下面的,再不行的话就得用常规办法了.
Dim AccessConn As New System.Data.OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=C:\Test Files\db1 XP.mdb")
AccessConn.Open()
'New table
Dim AccessCommand As New System.Data.OleDb.OleDbCommand("SELECT * INTO [tbl1] FROM [Text;DATABASE=C:\Documents and Settings\...\My Documents\My Database\Text].[tbl1.txt]", AccessConn)
'Existing table
'Dim AccessCommand As New System.Data.OleDb.OleDbCommand("INSERT INTO [tbl1] (F1, F2, F3) SELECT F1, F2, F3 FROM [Text;DATABASE=C:\Documents and Settings\...\My Documents\My Database\Text].[tbl1.txt]", AccessConn)
AccessCommand.ExecuteNonQuery()
AccessConn.Close()
The schema.ini file would look something like following:
[tbl1.txt]
ColNameHeader=False
Format=TabDelimited
CharacterSet=ANSI
