Android Question timeout for "Wait For"

There is no built in timeout (it is not possible to create a generic one). For specific cases there are ways to create a timeout.

Remember that nothing bad happens when a Wait For call never returns. Its more or less like an event sub that is never called.

You need to provide more information.

for example like this dummy code :

Public Sub DoTask1
asyncsend("xxxxx")
wait for asyncreceive
asyncsend("yyyyy")
End Sub

Private Sub async_NewData (Buffer() As Byte)
dim cmd as string = BytesToString(Buffer,0,Buffer.length,"UTF8")
if cmd = "abc" then callsub(Me,"asyncreceive")
End Sub


what happened if async_NewData is never arrive, or arrive with data I dont want. Then "wait for asyncreceive" will wait there, and never continue, right ?
If i need to wait this reply maximumly xx seconds, if not receive then something wrong happened, ... how to do it ?

Of course maybe a timer can be created to trigger timeout, but then how I can destroy that "wait for" ?

Please use [code]code here...[/code] tags when posting code.

It will never continue but it doesn't mean that something bad will happen. At some point you will call DoTask1 again and it will replace the previous waiting resumable sub.

You can implement a timeout with this code:

BTW, always prefer CallSubDelayed over CallSub when used together with Wait For.
