I think Mike (and Ian, and some others) have reconsidered that pattern, after some feedback from MS /changes in the documentation in 1.1 on this. In particular, IIRC, there was the possibility of leakage when not calling EndInvoke. Check the archives for more information...

[mailto:[EMAIL PROTECTED] On Behalf Of Jade Burton Sent: 08 October 2003 11:15 To: [EMAIL PROTECTED] Subject: Re: [ADVANCED-DOTNET] Async Data Commands with ADO.Net But what's wrong with creating a thread? If you use the threadpool it's almost a one-liner! (Aside from the stub you'll prob have to write..) I guess it's personal preference whether you prefer to use special async APIs or whether you prefer fns that block until complete -- I personally avoid async APIs like the plague - they split my code into two parts - a caller and an event handler, which I find harder to manage (and which reminds me of the Win16 message model ;) ). For example: void SomeFunc() { LengthyTaskA(); LengthyTaskB(); } versus: void SomeFuncStart() { LengthyTaskA_Start(new [delegate to OnLengthyTaskAComplete]); } void OnLengthyTaskAComplete() { LengthyTaskB_Start(); } Even if I don't care about the result of the call or when it finishes I generally do not use async APIs because I like to be responsible for the lifetime of the threads in my app (or have that option in the future.)

[mailto:[EMAIL PROTECTED] Behalf Of Brian Gaer Sent: Wednesday, 8 October 2003 9:09 AM To: [EMAIL PROTECTED] Subject: [ADVANCED-DOTNET] Async Data Commands with ADO.Net Is anyone familiar with a method to have an ADO.Net command object perform a command.ExecuteNonQuery() asynchronously? The Stored Proc I am calling takes from 2 to 10 minutes to return, and I cannot wait for it and do not care what the results of the query are. I searched all over and the only option I have found is creating a new thread to make the database call. Is there any other way that anyone is aware of?
