由 孤街醉人 提交于 2019-11-30 07:39:42
问题 So, I have the same symptoms as described in C#/ASP.NET Oledb - MS Excel read "Unspecified error", but my my answer did not seem to fix it. Even always closing the OleDBConnection and disposing of it show the same symptoms. var connectionString = string.Format("Provider=Microsoft.ACE.OLEDB.12.0; data source={0}; Extended Properties=Excel 12.0;", _excelFile); using (var conn = new OleDbConnection(connectionString)) { try { DoSomething(); } finally { conn.Close(); } } Now I have found the

Why doesn't Microsoft support OLE DB connections to SQL Azure?

由 放肆的年华 提交于 2019-11-30 07:03:32
At the MSDN website it says, " Connecting to SQL Azure by using OLE DB is not supported. " There are other places on the web where folks report that it works fine for them after tweaking the server name in the connection string, such as here and here . Even SQL Server's Analysis Services uses OLE DB to connect to SQL Azure ! I develop a native/unmanaged application in Delphi that connects to SQL Server using ADO through the OLE DB provider for SQL Server. I'm considering adding SQL Azure support. It would be really helpful if I could reuse the majority of my code without not too much change. I

Extract OLE Object (pdf) from Access DB

由 会有一股神秘感。 提交于 2019-11-30 05:40:53

The trick is determining what part is the OLE Header and removing it.

由 为君一笑 提交于 2019-11-29 22:58:50
问题 I'm using the below Connection String with ACE.OLEDB.12.0 to read data from an XLSX Spreadsheet, but the I set IMEX=1, it does not work while when I remove IMEX=1 completely, it works fine. "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Working Folder\ICDE\Ramsden 4.xlsx;Extended Properties=""Excel 12.0 xml;HDR=No;IMEX=1;""" Can anyone explain why? Because I had the impression that IMEX=1 reads all data as text, so it was more secure! Thanks JP IMEX= <0/1/2> IMEX refers to IMport EXport
