  • using a stored procedure for login in c#

    - by Jin Yim
    Hi all, If I run a store procedure with two parameter values (admin, admin) (parameters : admin, admin) I get the following message : Session_UID User_Group_Name Sys_User_Name NULLAdministratorsNTMSAdmin No rows affected. (1 row(s) returned) @RETURN_VALUE = 0 Finished running [dbo].[p_SYS_Login]. -- To get the same message in c# I used the code following : string strConnection = Settings.Default.ConnectionString; using (SqlConnection conn = new SqlConnection(strConnection)) { using (SqlCommand cmd = new SqlCommand()) { SqlDataReader rdr = null; cmd.Connection = conn; cmd.CommandText = "p_SYS_Login"; cmd.CommandType = CommandType.StoredProcedure; SqlParameter paramReturnValue = new SqlParameter(); paramReturnValue.ParameterName = "@RETURN_VALUE"; paramReturnValue.SqlDbType = SqlDbType.Int; paramReturnValue.SourceColumn = null; paramReturnValue.Direction = ParameterDirection.ReturnValue; cmd.Parameters.Add(paramReturnValue); cmd.Parameters.Add(paramGroupName); cmd.Parameters.Add(paramUserName); cmd.Parameters.AddWithValue("@Sys_Login", "admin"); cmd.Parameters.AddWithValue("@Sys_Password", "admin"); try { conn.Open(); rdr = cmd.ExecuteReader(); string test = (string)cmd.Parameters["@RETURN_VALUE"].Value; while (rdr.Read()) { Console.WriteLine("test : " + rdr[0]); } } catch (Exception ex) { string message = ex.Message; string caption = "MAVIS Exception"; MessageBoxButtons buttons = MessageBoxButtons.OK; MessageBox.Show( message, caption, buttons, MessageBoxIcon.Warning, MessageBoxDefaultButton.Button1); } finally { cmd.Dispose(); conn.Close(); } } } but I get nothing in SqlDataReader rdr ; is there something I am missing ?

  • jQuery Form Validation being bypassed

    - by user1953681
    Can someone tell me what is wrong with my jQuery validation? It is not validating my form, rather, just ignoring the code resulting in no check of the inputs. Form: <form class="form" accept-charset="UTF-8" action="URL-to-complete-form" method="POST" onsubmit="return validateForm();"> <input class="form-name" type="text" placeholder="Name"></div> <input class="form-email" type="text"placeholder="Email"></div> <input style="background-color: #fc8f12;" type="submit" value="Subscribe"> </div> </form> Javascript: function validateForm() { // Validate Name var title = $(".form-name").val(); if (title=="" ||title=="Name" || title==null) { } else { alert("Please enter a name!"); } // Validate Email var email = $(".form-email").val(); if ((/(.+)@(.+){2,}\.(.+){2,}/.test(email)) || email=="" || email=="Email" || email==null) { } else { alert("Please enter a valid email"); } return false; } Thank you all for your time and help.

  • Android Camera intent creating two files

    - by Kyle Ramstad
    I am making a program that takes a picture and then shows it's thumbnail. When using the emulator all goes well and the discard button deletes the photo. But on a real device the camera intent saves the image at the imageUri variable and a second one that is named like if I had just opened up the camera and took a picture by itself. private static final int CAMERA_PIC_REQUEST = 1337; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.camera); //start camera values = new ContentValues(); values.put(MediaStore.Images.Media.TITLE, "New Picture"); values.put(MediaStore.Images.Media.DESCRIPTION,"From your Camera"); imageUri = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values); image = (ImageView) findViewById(R.id.ImageView01); Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri); startActivityForResult(intent, CAMERA_PIC_REQUEST); //save the image buttons Button save = (Button) findViewById(R.id.Button01); Button close = (Button) findViewById(R.id.Button02); } @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { if (requestCode == CAMERA_PIC_REQUEST && resultCode == RESULT_OK) { try{ thumbnail = MediaStore.Images.Media.getBitmap(getContentResolver(), imageUri); image.setImageBitmap(thumbnail); } catch(Exception e){ e.printStackTrace(); } } else{ finish(); } } public void myClickHandler(View view) { switch (view.getId()) { case R.id.Button01: finish(); break; case R.id.Button02: dicard(); } } private void dicard(){ getContentResolver().delete(imageUri, null, null); finish(); }

  • javascript read a text file

    - by Cyprus106
    I have looked everywhere and surprisingly can't find a good solution to this! I've got the following code that is supposed to read a text file and display it's contents. But it's not reading, for some reason. Am I doing something wrong? FTR, I can't use PHP for this. It's gotta be Javascript. var txtFile = new XMLHttpRequest(); txtFile.open("GET", "http://www.mysite.com/todaysTrivia.txt", true); txtFile.send(null); txtFile.onreadystatechange = function() { if (txtFile.readyState == 4) { // Makes sure the document is ready to parse. alert(txtFile.responseText+" - "+txtFile.status); //if (txtFile.status === 200) { // Makes sure it's found the file. var doc = document.getElementById("Trivia-Widget"); if (doc) { doc.innerHTML = txtFile.responseText ; } //} } txtFile.send(null); } Any good ideas what I'm doing wrong? It just keeps givimg me a zero status.

  • FragmentActivity doesn't see activity in onActivityCreate(), after screen orientation changed

    - by hai bison
    I'm using Android support library v13. There is a strange thing I couldn't understand. When creating new activity, I load fragment as: Main activity layout: ... <FrameLayout android:id="@+id/fragment_1" ... /> In onCreate() of main activity: mFragment = (FragmentActivity) getSupportFragmentManager().findFragmentById(R.id.fragment_1); // if screen orientation changed, no need to create new instance of fragment if (mFragment == null) { mFragment = ...; // create new instance of fragment FragmentTransaction ft = getSupportFragmentManager().beginTransaction(); ft.replace(R.id.fragment_1, mFragment); // because this is called ONCE, we can use this method ft.commitAllowingStateLoss(); } Now, everything works perfectly in emulators 1.5, 1.6 and 2.2. I have a phone 2.2.2. But there is an exception: if the app is running, and screen orientation changed. Inside onActivityCreated(), getActivity() sometimes returns null. This only happens in emulators 1.5/ 1.6/ 2.2. My phone 2.2.2 works very well, I test hundreds of times but never catch that bug. Even other emulators 3.x, 4.x work well too. Unfortunately I don't have phone 1.5/ 1.6/ 2.2. So did you have experience with this? Is that a bug of the support library, or emulators? Could you please help me? Thank you in advance.

  • ViewGroup{TextView,...}.getMeasuredHeight gives wrong value is smaller than real height.

    - by Dewr
    ViewGroup(the ViewGroup is containing TextViews having long text except line-feed-character).getMeasuredHeight returns wrong value... that is smaller than real height. how to get rid of this problem? here is the java code: ;public static void setListViewHeightBasedOnChildren(ListView listView) { ListAdapter listAdapter = listView.getAdapter(); if (listAdapter == null) { // pre-condition return; } int totalHeight = 0; int count = listAdapter.getCount(); for (int i = 0; i < count; i++) { View listItem = listAdapter.getView(i, null, listView); listItem.measure(View.MeasureSpec.AT_MOST, View.MeasureSpec.UNSPECIFIED); totalHeight += listItem.getMeasuredHeight(); } ViewGroup.LayoutParams params = listView.getLayoutParams(); params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1)); listView.setLayoutParams(params); } ; and here is the list_item_comments.xml:; {RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" } {RelativeLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_centerVertical="true" android:layout_marginLeft="8dip" android:layout_marginRight="8dip" } {TextView android:id="@+id/list_item_comments_nick" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textSize="16sp" style="@style/WhiteText" /} {TextView android:id="@+id/list_item_comments_time" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:textSize="16sp" style="@style/WhiteText" /} {TextView android:id="@+id/list_item_comments_content" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_below="@id/list_item_comments_nick" android:autoLink="all" android:textSize="24sp" style="@style/WhiteText" /} {/RelativeLayout} {/RelativeLayout} ;

  • Message Handlers and the WeakReference issue

    - by user1058647
    The following message Handler works fine receiving messages from my service... private Handler handler = new Handler() { public void handleMessage(Message message) { Object path = message.obj; if (message.arg1 == 5 && path != null) //5 means its a single mapleg to plot on the map { String myString = (String) message.obj; Gson gson = new Gson(); MapPlot mapleg = gson.fromJson(myString, MapPlot.class); myMapView.getOverlays().add(new DirectionPathOverlay(mapleg.fromPoint, mapleg.toPoint)); mc.animateTo(mapleg.toPoint); } else { if (message.arg1 == RESULT_OK && path != null) { Toast.makeText(PSActivity.this, "Service Started" + path.toString(), Toast.LENGTH_LONG).show(); } else { Toast.makeText(PSActivity.this,"Service error" + String.valueOf(message.arg1), Toast.LENGTH_LONG).show(); } } }; }; However, even though it tests out alright in the AVD (I'm feeding it a large KML file via DDMS) the "object path = message.obj;" line has a WARNING saying "this Handler class should be static else leaks might occur". But if I say "static Handler handler = new Handler()" it won't compile complaining that I "cannot make a static reference to a non-static field myMapView. If I can't make such references, I can't do anything useful. This led me into several hours of googling around on this issue and learning more about weakReferences than I ever wanted to know. The often found reccomendation I find is that I should replace... private Handler handler = new Handler() with static class handler extends Handler { private final WeakReference<PSActivity> mTarget; handler(PSActivity target) { mTarget = new WeakReference<PSActivity>(target); } But this won't compile still complaining that I can't make a static reference to a non-dtatic field. So, my question a week or to ago was "how can I write a message handler for android so my service can send data to my activity. Even though I have working code, the question still stands with the suffix "without leaking memory". Thanks, Gary

  • Unmanaged Process in Mono

    - by Residuum
    I want to start a quite expensive process (jackd) from a Mono application, and do not need full access to the process from the application itself. As the process is so expensive in terms of CPU usage, a Glib.IdleHandler for polling the process will not work, as it is never executed, and the GUI becomes unresponsive. Is there any way to have the cake and eating it at the same time in Mono? EDIT: I only need to be able to start and stop the process from Mono, I do not need information about the state of the process or if it has exited, as my application will register itself as a client to jackd, basically I need a "replacement" for bash's jackd &>/dev/null 2>&1 & for the System.Diagnostics.Process ;). Here is what I have so far for starting and stopping the process: public void StartJackd() { _jackd = new Process (); _jackd.StartInfo = _jackdStartup; if (_jackd.Start ()) { _jackd.EnableRaisingEvents = true; _jackd.Exited += JackdExited; } } public void StopJackd() { if (_jackd != null && !_jackd.HasExited) { _jackd.CloseMainWindow (); } } And somewhere else I have this code for registering the IdleHandler: GLib.Idle.Add(new GLib.IdleHandler(UpdateJackdConnections)); This handler will fire all the time, while the process is not running, but never, when jackd is running.

  • How to Load assembly to AppDomain with all references recursively?

    - by abatishchev
    I want to load to new AppDomin some assembly which has a complex references tree (MyDll.dll - Microsoft.Office.Interop.Excel.dll - Microsoft.Vbe.Interop.dll - Office.dll - stdole.dll) As far as I understood, when an assembly is been loaded to AppDomain, it's references would not be loaded automatically, and I have to load them manually. So when I do: string dir = @"SomePath"; // different from AppDomain.CurrentDomain.BaseDirectory string path = System.IO.Path.Combine(dir, "MyDll.dll"); AppDomainSetup setup = AppDomain.CurrentDomain.SetupInformation; setup.ApplicationBase = dir; AppDomain domain = AppDomain.CreateDomain("SomeAppDomain", null, setup); domain.Load(AssemblyName.GetAssemblyName(path)); and got FileNotFoundException: Could not load file or assembly 'MyDll, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified. I think the key word is one of its dependencies. Ok, I do next before domain.Load(AssemblyName.GetAssemblyName(path)); foreach (AssemblyName refAsmName in Assembly.ReflectionOnlyLoadFrom(path).GetReferencedAssemblies()) { domain.Load(refAsmName); } But got FileNotFoundException again, on another (referenced) assembly. How to load all references recursively? Have I to create references tree before loading root assembly? How to get an assembly's references without loading it?

  • EventAggregator, is it thread-safe?

    - by pfaz
    Is this thread-safe? The EventAggregator in Prism is a very simple class with only one method. I was surprised when I noticed that there was no lock around the null check and creation of a new type to add to the private _events collection. If two threads called GetEvent simultaneously for the same type (before it exists in _events) it looks like this would result in two entries in the collection. /// <summary> /// Gets the single instance of the event managed by this EventAggregator. Multiple calls to this method with the same <typeparamref name="TEventType"/> returns the same event instance. /// </summary> /// <typeparam name="TEventType">The type of event to get. This must inherit from <see cref="EventBase"/>.</typeparam> /// <returns>A singleton instance of an event object of type <typeparamref name="TEventType"/>.</returns> public TEventType GetEvent<TEventType>() where TEventType : EventBase { TEventType eventInstance = _events.FirstOrDefault(evt => evt.GetType() == typeof(TEventType)) as TEventType; if (eventInstance == null) { eventInstance = Activator.CreateInstance<TEventType>(); _events.Add(eventInstance); } return eventInstance; }

  • How to pass a value from the Jquery validation

    - by user2963960
    How can i pass a value from the jquery validation. I have an input box named clubCardNumber it should validate the length of the inputted value. If the length is equal to 10 the value passes to the hidden field named else validated it if its null or empty if all validations are true then its a clubCard. Here is how i implemented it on Javascript function validateClubCardNumber() { var varClubCardNumber = $('#clubCardNumber').val(); $('#phoneNumber').val(""); var returnVal = true; if ((null == varClubCardNumber || '' == trim(varClubCardNumber)){ return false; } if( varClubCardNumber.length < 10 ){ return false; }else if( varClubCardNumber.length == 10 ) { //The Phone Number field should contains numbers only var pattern = /^[0-9 -]*$/ ; var flag = pattern.test(trim(varClubCardNumber)); if(flag == false){ return false; }else{ $('#phoneNumber').val(varClubCardNumber); returnVal = true; } } } return returnVal; } HTML <div > <label for="clubCardNumber" >Card or Phone Number:</label> <input id="clubCardNumber" name="clubCardNumber" type="text" placeholder="Card or Phone Number" value="" maxlength="20"/> </div> <input type="hidden" id="phoneNumber" name="phoneNumber" value=""/>

  • Modify onclick function with jQuery

    - by Chris Barr
    I've got a button that has an onclick event in it, which was set on the back end from .NET. Beside it is a checkbox <button class="img_button" onclick="if(buttonLoader(this)){WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions('uxBtnRelease', '', true, '', 'somepage.aspx?oupid=5&fp=true', false, true))} return false;" type="button">Release</button> <input type="checkbox" checked="checked" id="myCheckbox"> When the checkbox is clicked, needs to change the value of the query string in the URL inside the onclick function of the button. So far I have this, and the idea is right, but I keep getting errors when it's run: "Uncaught SyntaxError: Unexpected token ILLEGAL" var defaultReleaseOnClick=null; $("#myCheckbox").click(function(){ var $releaseBtn = $(".img_button"); if(defaultReleaseOnClick==null) defaultReleaseOnClick=$releaseBtn.attr("onclick"); var newOnClickString = defaultReleaseOnClick.toString().replace(/&fp=[a-z]+'/i,"&fp="+this.checked); $releaseBtn.removeAttr("onclick").click(eval(newOnClickString)); }); I know it seems kinda hacky to convert the function to a string, do a replacement, and then try to convert it back to a function, but I don't know any other way to do it. Any ideas? I've set up a demo here: http://jsbin.com/asiwu4/edit

  • Is there a way to automatically load navigational property using the .NET Entity Framework?

    - by René Wolferink
    Stepping away more and more from writing SQL for my applications, I decided to give the Entity Framework a try. However, I've run into something I believe is causing me to write more code than I think is strictly necessary. When I accessed some navigational properties, I discovered that all many-to-one relations (simple references) were null and all one-to-many and many-to-many relations (EntityCollections) were empty. For example: I have a User with a reference to a Group. When I have retieved a User, by using a simple select-by-id, the Group property is null. If I want to access the Group I have to manually load it (using User.GroupReference.Load()). So I added a GetGroup() method in User which checks whether the Group is loaded already and, if not, does so and then returns the Group. Now this will result in a lot of highly similar methods for all navigational properties. And it all results in the navigational properties not being used, only my custom-made Get"PropertyName"() method's are now being used. I don't want to expand my queries (linq to entities) to immediately load all these properties, because it's not always known at first what is needed. And besides, it would cause a lot of queries to have to be made. Is there a way to configure the Entity Framework to load these objects when they happen to not be present? So when I access User.Group and the group is not loaded yet, it is loaded automatically? Or am I stuck using my own Get"PropertyName"() method's as long as I'm trying to load objects only on demand (or "just-in-time")? Some extra info: I'm using VS2008 SP1 with .NET 3.5 SP1. The Entity Framework I'm using is the one that got shipped with it.

  • XNA: What can cause SpriteBatch.End() to throw a NRE?

    - by Rosarch
    I don't understand what I'm doing wrong here: public void Draw(GameTime gameTime) // in ScreenManager { SpriteBatch.Begin(SpriteBlendMode.AlphaBlend); for (int i = 0; i < Screens.Count; i++) { if (Screens[i].State == Screen.ScreenState.HIDDEN) continue; Screens[i].Draw(gameTime); } SpriteBatch.End(); // null ref exception } SpriteBatch itself is not null. Some more context: public class MasterEngine : Microsoft.Xna.Framework.Game { public MasterEngine() { graphicsDeviceManager = new GraphicsDeviceManager(this); Components.Add(new GamerServicesComponent(this)); // ... spriteBatch = new SpriteBatch(graphicsDeviceManager.GraphicsDevice); screenManager = new ScreenManager(assets, gameEngine, graphicsDeviceManager.GraphicsDevice, spriteBatch); } //... protected override void Draw(GameTime gameTime) { screenManager.Draw(gameTime); // calls the problematic method base.Draw(gameTime); } } Am I failing to initialize something properly? UPDATE: As an experiment, I tried this to the constructor of MasterEngine: spriteBatch = new SpriteBatch(graphicsDeviceManager.GraphicsDevice); spriteBatch.Begin(); spriteBatch.DrawString(assets.GetAsset<SpriteFont>("calibri"), "ftw", new Vector2(), Color.White); spriteBatch.End(); This does not cause a NRE. hmm.... UPDATE 2: This does cause an NRE: protected override void Draw(GameTime gameTime) { spriteBatch.Begin(); spriteBatch.End(); // boned here //screenManager.Draw(gameTime); base.Draw(gameTime); }

  • Different results between Android Geocoder and Google Geocoding web service

    - by user3571822
    I am creating an Android application and I need to use the geolocation. I have started by using the Geocoder API from Android (android.location.geocoder) but it causes some issues (timed out waiting for response from server) which seem to be common according to what I have read. To make my application work when this kind of error occurs, I use the Geocoding web service. Now, the application works every time. The problem is that the results returned by the geocoder from API and the geocoder from the web service are not the same. For example the web service returns only 3 addresses with only city name and country whereas the geocoding from the API returns about 8 addresses with the feature name, the thoroughfare, the locality... The question is: is there a way to make the results from the web service exactly the same than the ones from the API? EDIT Here is my MainGeocoder class: public class MainGeocoder { private Geocoder geocoderAPI; private GeocoderRest geocoderRest; public MainGeocoder(Context context) { geocoderAPI = new Geocoder(context); geocoderRest = new GeocoderRest(context); } public List<Address> getFromLocationName(String search, int maxResults) { List<Address> addresses; try { addresses = geocoderAPI.getFromLocationName(search, maxResults); return addresses; } catch (IOException e) { e.printStackTrace(); try { addresses = geocoderRest.getFromLocationName(search, maxResults); return addresses; } catch (IOException e1) { return null; } catch (LimitExceededException e1) { return null; } } } } It basically tries to get the list of addresses from the API Geocoder. If an IO exception is thrown it gets this list from the web service by using the GeocoderRest class which has been pasted from here: http://stackoverflow.com/a/15117087/3571822

  • How can I use a compound condition in a join in Linq?

    - by Gary McGill
    Let's say I have a Customer table which has a PrimaryContactId field and a SecondaryContactId field. Both of these are foreign keys that reference the Contact table. For any given customer, either one or two contacts may be stored. In other words, PrimaryContactId can never be NULL, but SecondaryContactId can be NULL. If I drop my Customer and Contact tables onto the "Linq to SQL Classes" design surface, the class builder will spot the two FK relationships from the Customer table to the Contact table, and so the generated Customer class will have a Contact field and a Contact1 field (which I can rename to PrimaryContact and SecondaryContact to avoid confusion). Now suppose that I want to get details of all the contacts for a given set of customers. If there was always exactly one contact then I could write something like: from customer in customers join contact in contacts on customer.PrimaryContactId equals contact.id select ... ...which would be translated into something like: SELECT ... FROM Customer INNER JOIN Contact ON Customer.FirstSalesPersonId = Contact.id But, because I want to join on both the contact fields, I want the SQL to look something like: SELECT ... FROM Customer INNER JOIN Contact ON Customer.FirstSalesPersonId = Contact.id OR Customer.SecondSalesPersonId = Contact.id How can I write a Linq expression to do that?

  • Various way to stop a thread - which is the correct way

    - by Yan Cheng CHEOK
    I had came across different suggestion of stopping a thread. May I know, which is the correct way? Or it depends? Using Thread Variable http://download.oracle.com/javase/1.4.2/docs/guide/misc/threadPrimitiveDeprecation.html private volatile Thread blinker; public void stop() { blinker = null; } public void run() { Thread thisThread = Thread.currentThread(); while (blinker == thisThread) { try { thisThread.sleep(interval); } catch (InterruptedException e){ } repaint(); } } Using boolean flag private volatile boolean flag; public void stop() { flag = false; } public void run() { while (flag) { try { thisThread.sleep(interval); } catch (InterruptedException e){ } repaint(); } } Using Thread Variable together with interrupt private volatile Thread blinker; public void stop() { blinker.interrupt(); blinker = null; } public void run() { Thread thisThread = Thread.currentThread(); while (!thisThread.isInterrupted() && blinker == thisThread) { try { thisThread.sleep(interval); } catch (InterruptedException e){ } repaint(); } }

  • How can I unit test my custom validation attribute

    - by MightyAtom
    I have a custom asp.net mvc class validation attribute. My question is how can I unit test it? It would be one thing to test that the class has the attribute but this would not actually test that the logic inside it. This is what I want to test. [Serializable] [EligabilityStudentDebtsAttribute(ErrorMessage = "You must answer yes or no to all questions")] public class Eligability { [BooleanRequiredToBeTrue(ErrorMessage = "You must agree to the statements listed")] public bool StatementAgree { get; set; } [Required(ErrorMessage = "Please choose an option")] public bool? Income { get; set; } .....removed for brevity } [AttributeUsage(AttributeTargets.Class)] public class EligabilityStudentDebtsAttribute : ValidationAttribute { // If AnyDebts is true then // StudentDebts must be true or false public override bool IsValid(object value) { Eligability elig = (Eligability)value; bool ok = true; if (elig.AnyDebts == true) { if (elig.StudentDebts == null) { ok = false; } } return ok; } } I have tried to write a test as follows but this does not work: [TestMethod] public void Eligability_model_StudentDebts_is_required_if_AnyDebts_is_true() { // Arrange var eligability = new Eligability(); var controller = new ApplicationController(); // Act controller.ModelState.Clear(); controller.ValidateModel(eligability); var actionResult = controller.Section2(eligability,null,string.Empty); // Assert Assert.IsInstanceOfType(actionResult, typeof(ViewResult)); Assert.AreEqual(string.Empty, ((ViewResult)actionResult).ViewName); Assert.AreEqual(eligability, ((ViewResult)actionResult).ViewData.Model); Assert.IsFalse(((ViewResult)actionResult).ViewData.ModelState.IsValid); } The ModelStateDictionary does not contain the key for this custom attribute. It only contains the attributes for the standard validation attributes. Why is this? What is the best way to test these custom attributes? Thanks

  • Running processes at different times stops events from working - C

    - by Jamie Keeling
    Hello, This is a question which follows on from my previously answered question here At first I assumed I had a problem with the way I was creating my events due to the handles for OpenEvent returning NULL, I have managed to find the real cause however I am not sure how to go about it. Basically I use Visual Studio to launch both Process A and B at the same time, in the past my OpenEvent handle wouldn't work due to Process A looking for the address of the event a fraction of a second before Process B had time to make it. My solution was to simply allow Process B to run before Process A, fixing the error. The problem I have now is that Process B now reads events from Process A and as you expect it too returns a null handle when trying to open the events from Process A. I am creating the events in WM_CREATE message of both processes, furthermore I also create a thread at the same time to open/read/act upon the events. It seems if I run them at the same time they don't get chance to see each other, alternatively if I run one before the other one of them misses out and can't open a Handle. Can anyone suggest a solution? Thanks.

  • Encrypt string with public key only

    - by vlahovic
    i'm currently working on a android project where i need to encrypt a string using 128 bit AES, padding PKCS7 and CBC. I don't want to use any salt for this. I've tried loads of different variations including PBEKey but i can't come up with working code. This is what i currently have: String plainText = "24124124123"; String pwd = "BobsPublicPassword"; byte[] key = pwd.getBytes(); key = cutArray(key, 16); byte[] input = plainText.getBytes(); byte[] output = null; SecretKeySpec keySpec = null; keySpec = new SecretKeySpec(key, "AES"); Cipher cipher = Cipher.getInstance("AES/CBC/PKCS7Padding"); cipher.init(Cipher.ENCRYPT_MODE, keySpec); output = cipher.doFinal(input); private static byte[] cutArray(byte[] arr, int length){ byte[] resultArr = new byte[length]; for(int i = 0; i < length; i++ ){ resultArr[i] = arr[i]; } return resultArr; } Any help appreciated //Vlahovic
