I would like to do an asynchronous call to a server. The documentation has the following example to do that, but I am unsure where the HandleUrlEventO() event handler method gets called. The documentation mentions that "a roUrlEvent will be sent to the message port associated with the object". I assume that is how the HandleUrlEvent() event handler is called but I am unsure how to set up the port to do this. Can anyone assist?
Function GetAsync(url as String) newXfer = CreateObject("roUrlTransfer") newXfer.SetUrl(url) newXfer.AsyncGetToString() requestId = newXfer.GetIdentity().ToStr() m.pendingXfers[requestId] = newXfer End Function
Function HandleUrlEvent(event as Object) requestId = event.GetSourceIdentity().ToStr() xfer = m.pendingXfers[requestId] if xfer <> invalid then ' process it m.pendingXfers.Delete(requestId) end if End Function
