(Go) Get the LastErrorText for an Asynchronous Method CallSee more Async ExamplesDemonstrates how to get the LastErrorText information for a Chilkat method called asynchronously.
// This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. socket := chilkat.NewSocket() // The Async call simply creates the task. The "Connect" method has not yet been called. maxWaitMs := 5000 // Let's intentionally cause this connect to fail by giving it an invalid domain.. c := make(chan *chilkat.Task) go socket.ConnectAsync("amazonbladflakjsdflksadjf.com",443,true,maxWaitMs,c) task := <-c if socket.LastMethodSuccess() == false { fmt.Println(socket.LastErrorText()) socket.DisposeSocket() task.DisposeTask() return } // Start the background thread to run the task. var success bool if !success { fmt.Println(task.LastErrorText()) task.DisposeTask() socket.DisposeSocket() task.DisposeTask() return } // The application is now free to do anything else // For this example, we'll simply sleep and periodically // check to see if the Socket Connect if finished. for task.Finished() != true { // Sleep 1 ms. task.SleepMs(1) } // If the task completed, it means the method (in this case the Connect method) was called and returned success or failure. if task.StatusInt() != 7 { fmt.Println("Task did not complete.") fmt.Println("task status: ", task.Status()) task.DisposeTask() socket.DisposeSocket() task.DisposeTask() return } // Get the success/failure of the Connect // (This is the return value of the Connect method had it been called synchronously) success = task.GetResultBool() if success == false { // Get the LastErrorText for the Connect method call. // Had we called Connect synchronously, we would've simply accessed the socket object's LastErrorText property. // Instead, we get the task object's ResultErrorText. fmt.Println(task.ResultErrorText()) } else { fmt.Println("Connect succeeded.") } task.DisposeTask() socket.DisposeSocket() task.DisposeTask() |
