问题 This is a follow-up of this question: Ada: reading from a file . I would like to add an exception that checks if the file that I'm opening actually exists or not. I have made a separate procedure to avoid code clutter. Here is the main code test_read.adb : with Ada.Text_IO; use Ada.Text_IO; with Ada.Long_Float_Text_IO; with Ada.Float_Text_IO; procedure Test_Read is Input_File : File_Type; Value : Long_Float; procedure Open_Data (File : in Ada.Text_IO.File_Type; Name : in String) is separate;

问题 Which .net exception should throw the client (or better re-throw), if it catches any unexpected exception from the server (e.g. wrapped in as FaultException via WCF, the server can be written on java) to handle it further on client as follow: The client shows the user a message about the possible bug in client/server The client provides developers the details of this exception (e.g. per e-mail) Example in the business layer: var client = new MyWcfClient()); try { // Try get data. var data =

问题 I am getting desperate here. I cant figure out why does this exception occur. I searched and read about this problem and it seems everyone managed to solve it with command.Parameters.Clear(), but this does not work for me. Here is my code: public class ProductsDataAccess : Connection { public static SqlParameter[] createParams(Products prod) { SqlParameter idParam = new SqlParameter("@id", prod.prodID); idParam.SqlDbType = System.Data.SqlDbType.VarChar; idParam.Size = 45; idParam.IsNullable =

问题 I have this code that should place a marker on a map using LatLng ... geocoder = Geocoder.create(); myOptions = MapOptions.create(); myOptions.setZoom(18); myOptions.setMapTypeId(MapTypeId.HYBRID); myOptions.setMapMaker(true); map = GoogleMap.create( Document.get().getElementById("map_canvas"),myOptions); location = LatLng.create(45.48592686713835,-73.49009937672122); map.setCenter(location.getGeometry().getLocation()); marker = Marker.create(); marker.setMap(map); marker.setPosition(location

问题 I am receiving a compile time error saying: No exception of type InputMismatchException can be thrown; an exception type must be a subclass of Throwable InputMismatchException.java As far as I'm aware InputMismatchException is an exception thrown by the Scanner when it receives invalid input, why then is this error preventing me from compiling? import java.util.*; public class InputMismatchException { public static void main(String[] args) { boolean continueInput = true; Scanner input = new

问题 the following small line throws a System.Security.SecurityException: Requested registry access is not allowed: RegistryKey _key = HKLM.OpenSubKey("path\\to\\my settings", false); Now.. what's the point some would ask? The point is that this runs ONLY when I am logged on . The exception is thrown if the program runs as scheduled task and nobody is logged on. the user who runs that task is local administrator the program does not run from a network share, it is located on the local disk I even

问题 I am getting the exception when trying to change text in the text property listener. The exception is exactly the same is this question. I used TextArea instead of TextField, but I think the source of the bug is the same. It's in the "TextInputControl.java". It seems to be Java 8's bug. @FXML private TextArea ta; ta.setText("12-"); // pre-set text ta.textProperty().addListener((observable, oldValue, newValue) -> { ta.setText("1"); // changed text }); This causes the exception on my machine.
