| Summary | 0002827: TJvErrorIndicator raise a "Thread error: The Parameter is incorrect (87)" error | ||||
| Description | When TJvErrorIndicator destroy the TJvBlinkThread instance in StopThread function, the exception is raised. The execute function of TJvBlinkThread contient a call to sleep function. | ||||
| Steps To Reproduce | JvErrorIndicator.BeginUpdate; JvErrorIndicator.Error[AControl1]:='A text'; JvErrorIndicator.EndUpdate; // now TJvBlinkThread is executed JvErrorIndicator.BeginUpdate; //<-- raise an exception JvErrorIndicator.Error[AControl2]:='A text'; JvErrorIndicator.EndUpdate; | ||||
| Additional Information | To correct this, remplace : procedure TJvErrorIndicator.StopThread; begin if FBlinkThread <> nil then FBlinkThread.Terminate; FreeAndNil(FBlinkThread); end; BY procedure TJvErrorIndicator.StopThread; begin if FBlinkThread <> nil then begin FBlinkThread.Terminate; FBlinkThread.WaitFor; end; FreeAndNil(FBlinkThread); end; | ||||
| Tags | No tags attached. | ||||

|
Fixed in the CVS version with : procedure TJvErrorIndicator.StopThread; begin if FBlinkThread <> nil then try FBlinkThread.Terminate; FBlinkThread.WaitFor; finally FreeAndNil(FBlinkThread); end; end; |
|
|
This is very strange, because Free is calling Terminate then WaitFor if the thread is still running. Hence, there shouldn't be any need to actually ask for the thread to stop. |
|
|
Ah well, anyway, this is resolved. |
