• Integration Services Throws an Error Reading Access 2007 Table

  - by Eric Flamm

  [Participant Table [1994]] Error: SSIS Error Code DTS_E_CANNOTACQUIRECONNECTIONFROMCONNECTIONMANAGER. The AcquireConnection method call to the connection manager "I:\My Documents\Flamm Consulting\Migrations.accdb" failed with error code 0xC0209303. There may be error messages posted before this with more information on why the AcquireConnection method call failed. Frankly, I'm confused about how SSIS should connect to Access 2007 - the UI just isn't very friendly - there's no file browser, for example. I'm wondering if there's something wrong with my install - missing drivers, etc.

• how to close a sqlconnection in asp.net

  - by stighy

  Hi guys, i would like to know if there's something wrong in this asp.net code: mydatareader = mycmd.executeReader() if myDataReader.HasRow then // Do something end if myConnection.Close() If i avoid to call a "MyDataReader.Close()" does the connection close anyway ? I ask this because i'm assuming that if call a "MyConn.Close" it automatically close the associated datareader... or am i wrong ? Thanks

• DATA command hangs

  - by Tharban

  Hello, what can i do, if a Mailserver accepts a connection but does not return any data? The default javax.mail implementation just hangs indefinitley. Event setting the smtp.timeout does not help - it still hangs. I even tried to set a custom SocketFactory to set the sotimeouts and solinger directly, but it still hangs. Somehow the socket does get kept alive? But how? Thx for any ideas! Ciao, Nils

• Solution for ora-1017 error for odp.net 2.111.7.0 ?

  - by Prithis

  Hi, As you are aware Oracle 11g has new facility of case sensitive password. We want to make use of it. When my C# application connects to oracle databse using ODP.Net 2.111.7.0 I am getting ora-1017 error. When we switch off this case sensitive feature it works without any change to the connection string. Any idea what is missing? is there any escape sequence we can use to specify lowercase characters in password? Thanks

• Using Volume Shadow Copy Service OK for backing up SQL Server Compact?

  - by Troy

  Would one expect a backup of a SQL Server Compact database file created with Volume Shadow Copy Service expected to be consistent? I know the big SQL Server has a VSS writer to ensure consistency.

• What's the easy way to test for 304 reponses?

  - by John Mee

  I need to test if my 304 responses are working, but my development environment is pretty hard set on force no-cache. Is there an easy way to modify the max-age value of the cache-control header before it goes out? I'm perhaps a bit optimistic in hoping chrome (or an extension, or FF) has a console command letting me alter the if-modified-since header then send the request. Maybe paste something into a telnet connection?

• Class destructor memory handling in C++

  - by wyatt

  What potential memory leaks won't an implicit destructor handle? I know that if you have anything stored on the heap it won't handle it, and if you have a connection to a file or a database, that needs to be handled manually. Is there anything else? What about, say, non-base data types like vectors? Also, in an explicit destructor, need you destroy non-heap variables which would have been destroyed by the implicit, or are they handled automatically? Thanks
