Import Data from Excel File (.cont)

As I has stated in my previous post regarding to Export Data Form an Excel file, there is one drawback lying behind them. The Sheet1 from the query actually is the name of the spreadsheet in your excel file. What if there is no Sheet1 inside the excel file? What if you don’t even know the sheet name?

Yes. I found this error when I tried to upload an excel file with different sheet name. And here is the solution for that.

To get the sheet name in your excel file, firstly, Microsoft DAO 3.5 Library is needed. Go to Project -> Reference -> Add Reference, select Microsoft DOA 3.5 Library from the list and add to your project. Here is the example code of how to get the first sheet in the excel file.
Dim strConn As String
Dim da As OleDbDataAdapter
Dim ds As New DataSet
Dim dao_dbE As dao.DBEngine
Dim dao_DB As DAO.Database
Dim strSheet As String

dao_dbE = New dao.DBEngine
dao_DB = dao_dbE.OpenDatabase("C:\test.xls", False, True, "Excel 8.0;")
strSheet = dao_DB.TableDefs(0).Name
strConn = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=C:\test.xls;Extended Properties=""Excel 8.0;"""

da = New OleDbDataAdapter("SELECT * FROM [" & _
strSheet & "]", strConn)
da.TableMappings.Add("Table", "Excel")

Hope this will help you work it out.
