Hi,
I am dealing with the new ParalleTask functions. It's very interesting for my application because I use httprequests to get results from my database and the user must wait a lot and the computer is locked during this.
It works so far ... but how can I show a progressbar ?
HttpSend runs in a parallel task and there is no access to any control .... |

| Call a procedure that runs on the main thread and displays a progressbar? You can set a procedure to run on the main thread by clicking the "1:30" timer button to the top-right of the procedure. Then choose main thread. |

Hi Curtis,
its much easier:
In the parallel task procedure:
cMyRequest..DownloadProgress..Procedure=HttpRequest_Progressbar_prepare
than :
procedure HttpRequest_Progressbar_prepare(TotalByte, TotalTransmitted)
ExecuteMainThread(HttpRequest_Progressbar,TotalByte,TotalTransmitted)
and
procedure http_request_progresbbar(TotalByte,TotalTransmitted)
Gauge(TotalTransmitted/TotalByte*100)
Multitask(-1)
Wow, what for a long waiting feature and how easy to implement. Thanks PCS !
Now the user can do things while waiting for the end of the httprequest.
The only thing I don´t get to run is cancel the task. I like to give the user a abort button.
I use
ParallelTaskRequestCancelation(ATask)
atask..canceled is true but the task runs till end .... |
