Queue

[solomon_13000]

I am interested to queue up any number of video files before storing it to the server folder. How can I accomplish this using asp.net 2.0 with C#?

You can achieve this using Asynchronous calling.

Private Delegate Function TimeConsumingTask(ByVal seconds As Integer) As Integer

'The WaitAll() method must execute on a MTA thread.
<MTAThread()> Public Sub Main()
'Dim ResultA, ResultB, ResultC As Integer

'Define and start three tasks.
Dim AsyncInvoker As New TimeConsumingTask(AddressOf Delay)
Dim AsyncResultA, AsyncResultB, AsyncResultC As IAsyncResult
AsyncResultA = AsyncInvoker.BeginInvoke(10, Nothing, Nothing)
AsyncResultB = AsyncInvoker.BeginInvoke(30, Nothing, Nothing)
AsyncResultC = AsyncInvoker.BeginInvoke(15, Nothing, Nothing)

Response.Write("Call A is: " & AsyncResultA.IsCompleted.ToString() & "<BR>")
Response.Write("Call B is: " & AsyncResultB.IsCompleted.ToString() & "<BR>")
Response.Write("Call C is: " & AsyncResultC.IsCompleted.ToString() & "<BR>")

Dim WaitHandles() As Threading.WaitHandle = {AsyncResultA.AsyncWaitHandle, AsyncResultB.AsyncWaitHandle, AsyncResultC.AsyncWaitHandle}

Threading.WaitHandle.WaitAll(WaitHandles)

Response.Write("Call A is: " & AsyncResultA.IsCompleted.ToString() & "<BR>")
Response.Write("Call B is: " & AsyncResultB.IsCompleted.ToString() & "<BR>")
Response.Write("Call C is: " & AsyncResultC.IsCompleted.ToString())
End Sub

Private Function Delay(ByVal Seconds As Integer) As Integer
Dim StartTime As DateTime = DateTime.Now
Do
'Do Nothing.
Loop While DateTime.Now.Subtract(StartTime).TotalSeconds < Seconds
Return Seconds
End Function


End Class

from the code I see, where will a file reside before storing it into a folder? Because im planning to upload a file to a queue before storing it into a folder.

Never tried it before but i would think it would be held in memory. I would add code for uploading the fill in one handler then do the save command in the last handler to fire.

This is only an idea i haven't tried this before myself.

let me know how you get on.
