Save file dialog box

Question

I want  to save a excel file dynamically to a desired location using vb.net savedialog box control.

What I need, is to get the new created file path (i.e Same as  save  as dialog in windows) .

I'll Use the Open file()  elsewhere. When I Use the below code, it says no file present.

FYI..

SaveFileDialog_admin.Filter = "Excel|*.Xls"

        SaveFileDialog_admin.Title = "Save An Excel File"

        SaveFileDialog_admin.ShowDialog()

        Dim file_name = SaveFileDialog_admin.FileName

        Label1.Text = Convert.ToString(file_name)

I just want to know how can I get the Newly created File Path And the file name for later  use.

Any Suggestion or  answer is welcomed.

Thanks in advance.

ASAP
