Running a SQL Server stored proecdure with OPENROWSET in VB.Net - sql

Question

I am trying to automatically import tables from an excel sheet into a table in an SQL database via VB.net. So far I have done the following:
I created a stored procedure in the database which imports the table via openrowset:
CREATE PROCEDURE ImportTable
AS
SET NOCOUNT ON;
EXEC sp_MSset_oledb_prop N'Microsoft.ACE.OLEDB.12.0', N'AllowInProcess', 1
EXEC sp_MSset_oledb_prop N'Microsoft.ACE.OLEDB.12.0', N'DynamicParameters', 1
SELECT *
INTO [Table]
FROM OPENROWSET('Microsoft.ACE.OLEDB.12.0',
'Excel 12.0; Database=C:\ExcelFile.xlsm', Table$);
GO
Once created this procedure works perfectly when executed in SSMS.
I then wrote a script in VB.net to run the stored procedure with the same login details:
Dim ConnectionString As String
Dim sqlCon As SqlConnection
' Open a database connection and use it to run the stored procedure
ConnectionString = "Data Source=ServerName;" &
"Initial Catalog=DBName;" &
"User=UserName;" &
"Password=Password;" &
"Integrated Security=SSPI;"
sqlCon = New SqlConnection(ConnectionString)
Using (sqlCon)
Dim sqlComm As New SqlCommand
sqlComm.Connection = sqlCon
sqlComm.CommandText = "ImportTable"
sqlComm.CommandType = CommandType.StoredProcedure
sqlCon.Open()
sqlComm.ExecuteNonQuery()
End Using
However when I try to run the SP in VB.net (or VB excel) I get the following error:
System.Data.SqlClient.SqlException: 'Cannot initialize the data source object of OLE DB provider "Microsoft.ACE.OLEDB.12.0" for linked server "(null)".
OLE DB provider "Microsoft.ACE.OLEDB.12.0" for linked server "(null)" returned message "Unspecified error".'
I have looked around and found multiple threads on getting this to work in SSMS, but no solutions for a situation where it runs fine in SSMS but not in VB.net.
Any idea why the SP wont run through a method external to SSMS?

First Make sure the Excel file isn't open.
Then you need to check whether you have installed the 2007 Office System Driver: Data Connectivity Components which is necessary for Microsoft OLEDB ACE 12.0 driver to work.
or you can
USE [master]
GO
EXEC master.dbo.sp_MSset_oledb_prop N'Microsoft.ACE.OLEDB.12.0', N'AllowInProcess', 1
GO
EXEC master.dbo.sp_MSset_oledb_prop N'Microsoft.ACE.OLEDB.12.0', N'DynamicParameters', 1
GO
