OpenFileDialog.Title = "打開 "
OpenFileDialog.Filter = ".xls|*.xls "
OpenFileDialog.InitialDirectory = My.Computer.FileSystem.SpecialDirectories.MyDocuments
If (OpenFileDialog.ShowDialog() = System.Windows.Forms.DialogResult.OK) Then
FileName = OpenFileDialog.FileName
End If
If FileName = " " Then
Exit Sub
End If
'If Dir(FileName) <> " " Then
' Kill(FileName)
'End If
MyOleDbCn.ConnectionString = "Provider=Microsoft.Jet.OleDb.4.0; " & _
"Data Source= " & FileName & "; " & _
"Extended ProPerties= " "Excel 8.0;HDR=Yes;IMEX=1 " " "
MyOleDbCn.Close()
MyOleDbCn.Open()
Dim ComStr As String
ComStr = "SELECT * FROM [Sheet 1$] "
Dim adapter As New OleDb.OleDbDataAdapter(ComStr, MyOleDbCn)
dt.Clear()
adapter.Fill(dt)
dt.AcceptChanges()
Me.DataGridView1.DataSource = dt
MyOleDbCn.Close()
