  • ASP.NET MVC - Pass array object as a route value within Html.ActionLink(...)

    - by Mike
    I have a method that returns an array (string[]) and I'm trying to pass this array of strings into an Action Link so that it will create a query string similar to: /Controller/Action?str=val1&str=val2&str=val3...etc But when I pass new { str = GetStringArray() } I get the following url: /Controller/Action?str=System.String%5B%5D So basically it's taking my string[] and running .ToString() on it to get the value. Any ideas? Thanks!

  • Is there a way of recover from an Exception in Directory.EnumerateFiles ?

    - by Magnus Johansson
    In .NET 4, there's this Directory.EnumerateFiles() method with recursion that seems handy. However, if an Exception occurs within a recursion, how can I continue/recover from that and continuing enumerate the rest of the files? try { var files = from file in Directory.EnumerateFiles(@"c:\", "*.*", SearchOption.AllDirectories) select new { File = file }; Console.WriteLine(files.Count().ToString()); } catch (UnauthorizedAccessException uEx) { Console.WriteLine(uEx.Message); } catch (PathTooLongException ptlEx) { Console.WriteLine(ptlEx.Message); }

  • How to display a TimeSpan in MVC Razor

    - by John Mitchell
    So I have a duration in seconds of a video and I would like to display that duration in Razor. Currently I am using @TimeSpan.FromSeconds(item.Duration).ToString() However the rest of the code I am using uses @Html.DisplayFor(modelItem => item.Description) Is there way to get the duration (currently an int) to display a as a timespan? using the @Html.DisplayFor syntax. The item.duration is pulling form a Entity Framework model which is held as a int in the database.

  • Nested property binding

    - by EtherealMonkey
    Recently, I have been trying to wrap my mind around the BindingList<T> and INotifyPropertChanged. More specifically - How do I make a collection of objects (having objects as properties) which will allow me to subscribe to events throughout the tree? To that end, I have examined the code offered as examples by others. One such project that I downloaded was Nested Property Binding - CodeProject by "seesharper". Now, the article explains the implementation, but there was a question by "Someone@AnotherWorld" about "INotifyPropertyChanged in nested objects". His question was: Hi, nice stuff! But after a couple of time using your solution I realize the ObjectBindingSource ignores the PropertyChanged event of nested objects. E.g. I've got a class 'Foo' with two properties named 'Name' and 'Bar'. 'Name' is a string an 'Bar' reference an instance of class 'Bar', which has a 'Name' property of type string too and both classes implements INotifyPropertyChanged. With your binding source reading and writing with both properties ('Name' and 'Bar_Name') works fine but the PropertyChanged event works only for the 'Name' property, because the binding source listen only for events of 'Foo'. One workaround is to retrigger the PropertyChanged event in the appropriate class (here 'Foo'). What's very unclean! The other approach would be to extend ObjectBindingSource so that all owner of nested property which implements INotifyPropertyChanged get used for receive changes, but how? Thanks! I had asked about BindingList<T> yesterday and received a good answer from Aaronaught. In my question, I had a similar point as "Someone@AnotherWorld": if Keywords were to implement INotifyPropertyChanged, would changes be accessible to the BindingList through the ScannedImage object? To which Aaronaught's response was: No, they will not. BindingList only looks at the specific object in the list, it has no ability to scan all dependencies and monitor everything in the graph (nor would that always be a good idea, if it were possible). I understand Aaronaught's comment regarding this behavior not necessarily being a good idea. Additionally, his suggestion to have my bound object "relay" events on behalf of it's member objects works fine and is perfectly acceptable. For me, "re-triggering" the PropertyChanged event does not seem so unclean as "Someone@AnotherWorld" laments. I do understand why he protests - in the interest of loosely coupled objects. However, I believe that coupling between objects that are part of a composition is logical and not so undesirable as this may be in other scenarios. (I am a newb, so I could be waaayyy off base.) Anyway, in the interest of exploring an answer to the question by "Someone@AnotherWorld", I altered the MainForm.cs file of the example project from Nested Property Binding - CodeProject by "seesharper" to the following: using System; using System.Collections.Generic; using System.ComponentModel; using System.Core.ComponentModel; using System.Windows.Forms; namespace ObjectBindingSourceDemo { public partial class MainForm : Form { private readonly List<Customer> _customers = new List<Customer>(); private readonly List<Product> _products = new List<Product>(); private List<Order> orders; public MainForm() { InitializeComponent(); dataGridView1.AutoGenerateColumns = false; dataGridView2.AutoGenerateColumns = false; CreateData(); } private void CreateData() { _customers.Add( new Customer(1, "Jane Wilson", new Address("98104", "6657 Sand Pointe Lane", "Seattle", "USA"))); _customers.Add( new Customer(1, "Bill Smith", new Address("94109", "5725 Glaze Drive", "San Francisco", "USA"))); _customers.Add( new Customer(1, "Samantha Brown", null)); _products.Add(new Product(1, "Keyboard", 49.99)); _products.Add(new Product(2, "Mouse", 10.99)); _products.Add(new Product(3, "PC", 599.99)); _products.Add(new Product(4, "Monitor", 299.99)); _products.Add(new Product(5, "LapTop", 799.99)); _products.Add(new Product(6, "Harddisc", 89.99)); customerBindingSource.DataSource = _customers; productBindingSource.DataSource = _products; orders = new List<Order>(); orders.Add(new Order(1, DateTime.Now, _customers[0])); orders.Add(new Order(2, DateTime.Now, _customers[1])); orders.Add(new Order(3, DateTime.Now, _customers[2])); #region Added by me OrderLine orderLine1 = new OrderLine(_products[0], 1); OrderLine orderLine2 = new OrderLine(_products[1], 3); orderLine1.PropertyChanged += new PropertyChangedEventHandler(OrderLineChanged); orderLine2.PropertyChanged += new PropertyChangedEventHandler(OrderLineChanged); orders[0].OrderLines.Add(orderLine1); orders[0].OrderLines.Add(orderLine2); #endregion // Removed by me in lieu of region above. //orders[0].OrderLines.Add(new OrderLine(_products[0], 1)); //orders[0].OrderLines.Add(new OrderLine(_products[1], 3)); ordersBindingSource.DataSource = orders; } #region Added by me // Have to wait until the form is Shown to wire up the events // for orderDetailsBindingSource. Otherwise, they are triggered // during MainForm().InitializeComponent(). private void MainForm_Shown(object sender, EventArgs e) { orderDetailsBindingSource.AddingNew += new AddingNewEventHandler(orderDetailsBindSrc_AddingNew); orderDetailsBindingSource.CurrentItemChanged += new EventHandler(orderDetailsBindSrc_CurrentItemChanged); orderDetailsBindingSource.ListChanged += new ListChangedEventHandler(orderDetailsBindSrc_ListChanged); } private void orderDetailsBindSrc_AddingNew( object sender, AddingNewEventArgs e) { } private void orderDetailsBindSrc_CurrentItemChanged( object sender, EventArgs e) { } private void orderDetailsBindSrc_ListChanged( object sender, ListChangedEventArgs e) { ObjectBindingSource bindingSource = (ObjectBindingSource)sender; if (!(bindingSource.Current == null)) { // Unsure if GetType().ToString() is required b/c ToString() // *seems* // to return the same value. if (bindingSource.Current.GetType().ToString() == "ObjectBindingSourceDemo.OrderLine") { if (e.ListChangedType == ListChangedType.ItemAdded) { // I wish that I knew of a way to determine // if the 'PropertyChanged' delegate assignment is null. // I don't like the current test, but it seems to work. if (orders[ ordersBindingSource.Position].OrderLines[ e.NewIndex].Product == null) { orders[ ordersBindingSource.Position].OrderLines[ e.NewIndex].PropertyChanged += new PropertyChangedEventHandler( OrderLineChanged); } } if (e.ListChangedType == ListChangedType.ItemDeleted) { // Will throw exception when leaving // an OrderLine row with unitialized properties. // // I presume this is because the item // has already been 'disposed' of at this point. // *but* // Will it be actually be released from memory // if the delegate assignment for PropertyChanged // was never removed??? if (orders[ ordersBindingSource.Position].OrderLines[ e.NewIndex].Product != null) { orders[ ordersBindingSource.Position].OrderLines[ e.NewIndex].PropertyChanged -= new PropertyChangedEventHandler( OrderLineChanged); } } } } } private void OrderLineChanged(object sender, PropertyChangedEventArgs e) { MessageBox.Show(e.PropertyName, "Property Changed:"); } #endregion } } In the method private void orderDetailsBindSrc_ListChanged(object sender, ListChangedEventArgs e) I am able to hook up the PropertyChangedEventHandler to the OrderLine object as it is being created. However, I cannot seem to find a way to unhook the PropertyChangedEventHandler from the OrderLine object before it is being removed from the orders[i].OrderLines list. So, my questions are: Am I simply trying to do something that is very, very wrong here? Will the OrderLines object that I add the delegate assignments to ever be released from memory if the assignment is not removed? Is there a "sane" method of achieving this scenario? Also, note that this question is not specifically related to my prior. I have actually solved the issue which had prompted me to inquire before. However, I have reached a point with this particular topic of discovery where my curiosity has exceeded my patience - hopefully someone here can shed some light on this?

  • Custom DataAnnotation attribute with datastore access in ASP.NET MVC 2

    - by mare
    I have my application designed with Repository pattern implemented and my code prepared for optional dependency injection in future, if we need to support another datastore. I want to create a custom validation attribute for my content objects. This attribute should perform some kind of datastore lookup. For instance, I need my content to have unique slugs. To check if a Slug already exist, I want to use custom DataAnnotation attribute in my Base content object (instead of manually checking if a slug exists each time in my controller's Insert actions). Attribute logic would do the validation. So far I have come up with this: public class UniqueSlugAttribute : ValidationAttribute { private readonly IContentRepository _repository; public UniqueSlugAttribute(ContentType contentType) { _repository = new XmlContentRepository(contentType); } public override bool IsValid(object value) { if (string.IsNullOrWhiteSpace(value.ToString())) { return false; } string slug = value.ToString(); if(_repository.IsUniqueSlug(slug)) return true; return false; } } part of my Base content class: ... [DataMember] public ContentType ContentType1 { get; set; } [DataMember] [Required(ErrorMessageResourceType = typeof (Localize), ErrorMessageResourceName = "Validation_SlugIsBlank")] [UniqueSlug(ContentType1)] public string Slug { get { return _slug; } set { if (!string.IsNullOrEmpty(value)) _slug = Utility.RemoveIllegalCharacters(value); } } ... There's an error in line [UniqueSlug(ContentType1)] saying: "An attribute argument must be a constant expression, typeof expression or array creation expression of an attribute parameter type." Let me explain that I need to provide the ContentType1 parameter to the Constructor of UniqueSlug class because I use it in my data provider. It is actually the same error that appears if you try do to this on the built-in Required attribute: [Required(ErrorMessageResourceType = typeof (Localize), ErrorMessageResourceName = Resources.Localize.SlugRequired] It does not allow us to set it to dynamic content. In the first case ContentType1 gets known at runtime, in the second case the Resources.Localize.SlugRequired also gets known at runtime (because the Culture settings are assigned at runtime). This is really annoying and makes so many things and implementation scenarios impossible. So, my first question is, how to get rid of this error? The second question I have, is whether you think that I should redesign my validation code in any way?

  • Even if GridView.DataKeyNames is set, Gridview.DataKeys[] is still empty

    - by JustTryingToLearn
    hi GridView.DataKeynames stores the names of the primary key fields for the items displayed in a GridView control. 1) Even though I’ve set DataKeyNames, GridView still doesn’t store record’s primary key value(s) in DataKey object: protected void SqlDataSource1_Selected(object sender, SqlDataSourceStatusEventArgs e) { Label2.Text = GridView2.DataKeys[0].Value.ToString();//exception } Why not? 2) I assume when DataKeyNames is set, DataKey object stores both original and new values of a primary key ( assuming we issued an update command ) and when the update is finished, DataKey object discards the original value(s)? Thank you

  • AbcPDF renders the same page multiple times

    - by Steven
    I need to retrieve several pages and output this in a PDF document. I have the following page structure: Page 1 Sub 1 Sub 2 Sub 3 On page one, I have a link which executes the below code. What it does, is to retrieve child pages (one level) and put them in a page collection. Then I loop trough the page collection and retrieve each sub pages URL. This works. I've tested and seen that it retrieves 3 different URL's. The problem is that my PDF gets three pages of Page 1. It does not render Sub 1 to 3. Why isn't docID = document.AddImageUrl(pageLink) retrieving the pages? Websupergoo refers to a caching problem which may occur. But their solution did not help me. Any good suggestions anyone? protected void linkBtnCreateMultipagePDF_Click(object sender, EventArgs e) { string baseURL = Request.Url.ToString(); PageDataCollection pdc = GetChildren(CurrentPageLink); //Create PDF document Doc document = new Doc(); document.Rect.Inset(10, 20); int docID; string pageLink = string.Empty; foreach (PageData pd in pdc) { //This lops goes through the different pages and retrieves that pages URL pageLink = baseURL + pd.LinkURL; document.Page = document.AddPage(); // But for some reason, the same page is added here. docID = document.AddImageUrl(pageLink); //Chain pages together while (true) { if (!document.Chainable(docID)) break; document.Page = document.AddPage(); docID = document.AddImageToChain(docID); } } //Flatten file for (int i = 1; i <= document.PageCount; i++) { document.PageNumber = i; document.Flatten(); } byte[] theData = document.GetData(); Response.Clear(); Response.ContentType = "application/pdf"; Response.AddHeader("content-disposition", "inline; filename=MyPDF.PDF"); Response.AddHeader("content-length", theData.Length.ToString()); Response.BinaryWrite(theData); Response.End(); }

  • System.Data.SQLite parameter issue

    - by CasperT
    I have the following code: try { //Create connection SQLiteConnection conn = DBConnection.OpenDB(); //Verify user input, normally you give dbType a size, but Text is an exception var uNavnParam = new SQLiteParameter("@uNavnParam", SqlDbType.Text) { Value = uNavn }; var bNavnParam = new SQLiteParameter("@bNavnParam", SqlDbType.Text) { Value = bNavn }; var passwdParam = new SQLiteParameter("@passwdParam", SqlDbType.Text) {Value = passwd}; var pc_idParam = new SQLiteParameter("@pc_idParam", SqlDbType.TinyInt) { Value = pc_id }; var noterParam = new SQLiteParameter("@noterParam", SqlDbType.Text) { Value = noter }; var licens_idParam = new SQLiteParameter("@licens_idParam", SqlDbType.TinyInt) { Value = licens_id }; var insertSQL = new SQLiteCommand("INSERT INTO Brugere (navn, brugernavn, password, pc_id, noter, licens_id)" + "VALUES ('@uNameParam', '@bNavnParam', '@passwdParam', '@pc_idParam', '@noterParam', '@licens_idParam')", conn); insertSQL.Parameters.Add(uNavnParam); //replace paramenter with verified userinput insertSQL.Parameters.Add(bNavnParam); insertSQL.Parameters.Add(passwdParam); insertSQL.Parameters.Add(pc_idParam); insertSQL.Parameters.Add(noterParam); insertSQL.Parameters.Add(licens_idParam); insertSQL.ExecuteNonQuery(); //Execute query //Close connection DBConnection.CloseDB(conn); //Let the user know that it was changed succesfully this.Text = "Succes!

Instead of replacing them. I have tried making a breakpoint and checked the parameters, they do have the correct assigned values. So that is not the issue either. I have been tinkering with this a lot now, with no luck, can anyone help? Oh and for reference, here is the OpenDB method from the DBConnection class: public static SQLiteConnection OpenDB() { try { //Gets connectionstring from app.config const string myConnectString = "data source=data;"; var conn = new SQLiteConnection(myConnectString); conn.Open(); return conn; } catch (SQLiteException e) { MessageBox.Show(e.ToString(), "ALARM"); return null; } }

  • SSLException: Keystore does not support enabled cipher suites

    - by wurfkeks
    I want to implement a small android application, that works as SSL Server. After lot of problems with the right format of the keystore, I solved this and run into the next one. My keystore file is properly loaded by the KeyStore class. But when I try to open the server socket (socket.accept()) the following error is raised: javax.net.ssl.SSLException: Could not find any key store entries to support the enabled cipher suites. I generated my keystore with this command: keytool -genkey -keystore test.keystore -keyalg RSA -keypass ssltest -storepass ssltest -storetype BKS -provider org.bouncycastle.jce.provider.BouncyCastleProvider -providerpath bcprov.jar with the Unlimited Strength Jurisdiction Policy for Java SE6 applied to my jre6. I got a list of supported ciphers suites by calling socket.getSupportedCipherSuites() that prints a long list with very different combinations. But I don't know how to get a supported key. I also tried the android debug keystore after converting it to BKS format using portecle but get still the same error. Can anyone help and tell how I can generate a key that is compatible with one of the cipher suites? Version Information: targetSDK: 15 tested on emulator running 4.0.3 and real device running 2.3.3 BounceCastle 1.46 portecle 1.7 Code of my test application: public class SSLTestActivity extends Activity implements Runnable { SSLServerSocket mServerSocket; ToggleButton tglBtn; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); this.tglBtn = (ToggleButton)findViewById(R.id.toggleButton1); tglBtn.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { @Override public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { if (isChecked) { new Thread(SSLTestActivity.this).run(); } else { try { if (mServerSocket != null) mServerSocket.close(); } catch (IOException e) { Log.e("SSLTestActivity", e.toString()); } } } }); } @Override public void run() { try { KeyStore keyStore = KeyStore.getInstance(KeyStore.getDefaultType()); keyStore.load(getAssets().open("test.keystore"), "ssltest".toCharArray()); ServerSocketFactory socketFactory = SSLServerSocketFactory.getDefault(); mServerSocket = (SSLServerSocket) socketFactory.createServerSocket(8080); while (!mServerSocket.isClosed()) { Socket client = mServerSocket.accept(); PrintWriter output = new PrintWriter(client.getOutputStream(), true); output.println("So long, and thanks for all the fish!"); client.close(); } } catch (Exception e) { Log.e("SSLTestActivity", e.toString()); } } }

  • Sharepoint 2007 - cant find my modifications to web.config in SpWebApplication.WebConfigModification

    - by user303672
    Hi, I cant seem to find the modifications I made to web.config in my FeatureRecievers Activated event. I try to get the modifications from the SpWebApplication.WebConfigModifications collection in the deactivate event, but this is always empty.... And the strangest thing is that my changes are still reverted after deactivating the feature... My question is, should I not be able to view all changes made to the web.config files when accessing the SpWebApplication.WebConfigModifications collection in the Deactivating event? How should I go about to remove my changes explicitly? public class FeatureReciever : SPFeatureReceiver { private const string FEATURE_NAME = "HelloWorld"; private class Modification { public string Name; public string XPath; public string Value; public SPWebConfigModification.SPWebConfigModificationType ModificationType; public bool createOnly; public Modification(string name, string xPath, string value, SPWebConfigModification.SPWebConfigModificationType modificationType, bool createOnly) { Name = name; XPath = xPath; Value = value; ModificationType = modificationType; this.createOnly = createOnly; } } private Modification[] modifications = { new Modification("connectionStrings", "configuration", "<connectionStrings/>", SPWebConfigModification.SPWebConfigModificationType.EnsureChildNode, true), new Modification("add[@name='ConnectionString'][@connectionString='Data Source=serverName;Initial Catalog=DBName;User Id=UserId;Password=Pass']", "configuration/connectionStrings", "<add name='ConnectionString' connectionString='Data Source=serverName;Initial Catalog=DBName;User Id=UserId;Password=Pass'/>", SPWebConfigModification.SPWebConfigModificationType.EnsureChildNode, false) }; public override void FeatureActivated(SPFeatureReceiverProperties properties) { SPSite siteCollection = (properties.Feature.Parent as SPWeb).Site as SPSite; SPWebApplication webApplication = siteCollection.WebApplication; siteCollection.RootWeb.Title = "Set from activating code at " + DateTime.Now.ToString(); foreach (Modification entry in modifications) { SPWebConfigModification webConfigModification = CreateModification(entry); webApplication.WebConfigModifications.Add(webConfigModification); } webApplication.Farm.Services.GetValue<SPWebService>().ApplyWebConfigModifications(); webApplication.WebService.Update(); } public override void FeatureDeactivating(SPFeatureReceiverProperties properties) { SPSite siteCollection = (properties.Feature.Parent as SPWeb).Site as SPSite; SPWebApplication webApplication = siteCollection.WebApplication; siteCollection.RootWeb.Title = "Set from deactivating code at " + DateTime.Now.ToString(); IList<SPWebConfigModification> modifications = webApplication.WebConfigModifications; foreach (SPWebConfigModification modification in modifications) { if (modification.Owner == FEATURE_NAME) { webApplication.WebConfigModifications.Remove(modification); } } webApplication.Farm.Services.GetValue<SPWebService>().ApplyWebConfigModifications(); webApplication.WebService.Update(); } public override void FeatureInstalled(SPFeatureReceiverProperties properties) { } public override void FeatureUninstalling(SPFeatureReceiverProperties properties) { } private SPWebConfigModification CreateModification(Modification entry) { SPWebConfigModification spWebConfigModification = new SPWebConfigModification() { Name = entry.Name, Path = entry.XPath, Owner = FEATURE_NAME, Sequence = 0, Type = entry.ModificationType, Value = entry.Value }; return spWebConfigModification; } } Thanks for your time. /Hans

  • OSGI & Apache Commons-DBCP Classloading Issue

    - by Saul
    I inherited some code that is using the Apache commons-dbcp Connection pools in an OSGi bundle. This code works fine with Eclipse/Equinox OSGi version 3.4.3 (R34x_v20081215), commons-dbcp 1.2.2 and the postgres jdbc3 8.3.603 bundles from springsource.org. I wanted to modernize, maybe this was my first mistake! When I use the new version of Felix or Equinox OSGI Cores with the new postgresql JDBC3 or JDBC4 bundles along with the latest version of commons-dbcp (1.4.1), I am getting a classloading issue. I have done numerous searches and found that the commons-dbcp code should have a fix DBCP-214, but it still seems to fail. I have tried to put the org.postgresql on the commons-dbcp MANIFEST.MF import-package line, but that did not work either. I wrote a simple test in an activator that first does a basic class.forName() and DriverManager.getConnection(), this works fine, but when I add in BasicDataSource() and setup the connection with BasicDataSource.getConnection(), I get the ClassNotFoundException. See the code example below. Thanks in Advance for any help, suggestions, ... Sau! // This one fails with an exception public void dsTest() { BasicDataSource bds = new BasicDataSource(); ClassLoader cl; try { logger.debug("ContextClassLoader: {}", Thread.currentThread().getContextClassLoader().toString()); cl = this.getClass().getClassLoader(); logger.debug("ClassLoader: {}", cl); if (bds.getDriverClassLoader() != null) { logger.debug(bds.getDriverClassLoader().toString()); } // The failure is the same with and with the setDriverClassLoader() line bds.setDriverClassLoader(cl); bds.setDriverClassName("org.postgresql.Driver"); bds.setUrl("jdbc:postgresql://127.0.0.1/dbname"); bds.setUsername("user"); bds.setPassword("pword"); Class.forName("org.postgresql.Driver").newInstance(); conn = bds.getConnection(); Statement st = conn.createStatement(); ResultSet rs = st.executeQuery("SELECT COUNT(*) FROM table"); conn.close(); logger.debug("Closed DataSource Test"); } catch (Exception ex) { ex.printStackTrace(); logger.debug("Exception: {} ", ex.getMessage()); } } // This one works public void managerTest() { ClassLoader cl; try { cl = this.getClass().getClassLoader(); logger.debug("ClassLoader: {}", cl); Class.forName("org.postgresql.Driver").newInstance(); String url = "jdbc:postgresql://127.0.0.1/dbname"; conn = DriverManager.getConnection(url, "user", "pword"); Statement st = conn.createStatement(); ResultSet rs = st.executeQuery("SELECT COUNT(*) FROM table"); conn.close(); logger.debug("Closed Manger Test"); } catch (Exception ex) { ex.printStackTrace(); logger.debug("Exception: {} ", ex.getMessage()); } }

  • Handling Errors from HttpWebRequest.GetResponse

    - by Jason
    Hey experts - I'm having a ridiculous time trying to get an SMS API working (ZeepMobile, if you're interested) with .NET... I've been around .NET for a few years, but with all this social networking and API stuff, I need to get into the HttpWebRequest a bit. I'm new at it, but not completely new; I was able to hook up my site to Twitter without too much fuss (ie, I was able to modify someone's code to work for me). Anyways, the way their API works is to send an SMS message, you send them a POST and they respond back to you. I can send it just fine, but every time I do, rather than echo back something helpful to figure out what the error is, I get the Yellow Error Page Of Death (YEPOD) saying something to the effect of "The remote server returned an error: (400) Bad Request." This occurs on my line: '...creation of httpwebrequest here...' Dim myWebResponse As WebResponse myWebResponse = request.GetResponse() '<--- error line Is there any way to simply receive the error from the server rather than have the webserver throw an exception and give me the YEPOD? Or better yet, can anyone post a working example of their Zeep code? :) Thanks! EDIT: Here's my whole code block: Public Shared Function SendTextMessage(ByVal username As String, _ ByVal txt As String) As String Dim content As String = "user_id=" + _ username + "&body=" + Current.Server.UrlEncode(txt) Dim httpDate As String = DateTime.Now.ToString("r") Dim canonicalString As String = API_KEY & httpDate & content Dim encoding As New System.Text.UTF8Encoding Dim hmacSha As New HMACSHA1(encoding.GetBytes(SECRET_ACCESS_KEY)) Dim hash() As Byte = hmacSha.ComputeHash(encoding.GetBytes(canonicalString)) Dim b64 As String = Convert.ToBase64String(hash) 'connect with zeep' Dim request As HttpWebRequest = CType(WebRequest.Create(_ "https://api.zeepmobile.com/messaging/2008-07-14/send_message"), HttpWebRequest) request.Method = "POST" request.ServicePoint.Expect100Continue = False ' set the authorization levels' request.Headers.Add("Authorization", "Zeep " & API_KEY & ":" & b64) request.ContentType = "application/x-www-form-urlencoded" request.ContentLength = content.Length ' set up and write to stream' Dim reqStream As New StreamWriter(request.GetRequestStream()) reqStream.Write(content) reqStream.Close() Dim msg As String = "" msg = reqStream.ToString Dim myWebResponse As WebResponse Dim myResponseStream As Stream Dim myStreamReader As StreamReader myWebResponse = request.GetResponse() myResponseStream = myWebResponse.GetResponseStream() myStreamReader = New StreamReader(myResponseStream) msg = myStreamReader.ReadToEnd() myStreamReader.Close() myResponseStream.Close() ' Close the WebResponse' myWebResponse.Close() Return msg End Function

  • use bouncy castle libraries to encrypt files using public key from digital certificate

    - by mike
    I got the public key from the certificate, keypair is a java.security.KeyPair object String public_key = keypair.getPublic().toString(); I want to send this to the via an http connection to a J2me application. I cannot find any documentation to convert the transmitted string to a Public key that can be used to encrypt Strings. I also want the J2me to verify signed strings from the server. I want to then send the encrypted strings back to the server.

  • Apache HttpClient Digest authentication

    - by Milan Jovic
    Hi, Basically what I need to do is to perform digest authentication. First thing I tried is the official example available here. But when I try to execute it(with some small changes, Post instead of the the Get method) I get a org.apache.http.auth.MalformedChallengeException: missing nonce in challange at org.apache.http.impl.auth.DigestScheme.processChallenge(DigestScheme.java:132) When this failed I tried using: DefaultHttpClient client = new DefaultHttpClient(); client.getCredentialsProvider().setCredentials(new AuthScope(null, -1, null), new UsernamePasswordCredentials("<username>", "<password>")); HttpPost post = new HttpPost(URI.create("http://<someaddress>")); List<NameValuePair> nvps = new ArrayList<NameValuePair>(); nvps.add(new BasicNameValuePair("domain", "<username>")); post.setEntity(new UrlEncodedFormEntity(nvps, HTTP.UTF_8)); DigestScheme digestAuth = new DigestScheme(); digestAuth.overrideParamter("algorithm", "MD5"); digestAuth.overrideParamter("realm", "http://<someaddress>"); digestAuth.overrideParamter("nonce", Long.toString(new Random().nextLong(), 36)); digestAuth.overrideParamter("qop", "auth"); digestAuth.overrideParamter("nc", "0"); digestAuth.overrideParamter("cnonce", DigestScheme.createCnonce()); Header auth = digestAuth.authenticate(new UsernamePasswordCredentials("<username>", "<password>"), post); System.out.println(auth.getName()); System.out.println(auth.getValue()); post.setHeader(auth); HttpResponse ret = client.execute(post); ByteArrayOutputStream v2 = new ByteArrayOutputStream(); ret.getEntity().writeTo(v2); System.out.println("----------------------------------------"); System.out.println(v2.toString()); System.out.println("----------------------------------------"); System.out.println(ret.getStatusLine().getReasonPhrase()); System.out.println(ret.getStatusLine().getStatusCode()); At first I have only overridden "realm" and "nonce" DigestScheme parameters. But it turned out that PHP script running on the server requires all other params, but no matter if I specify them or not DigestScheme doesn't generate them when I call its authenticate() method. I've been struggling with this for two days, and no luck. Based on everything I think that the cause of the problem is the PHP script. It looks to me that it doesn't send a challenge when app tries to access it unauthorized. Any ideas anyone?

  • Cannot access app.config or settings.settings data

    - by J Carron
    I have 3.5 application needed to load a string from settings.settings or app.config. I made sure have reference to ConfigurationManager but very simple call from form load value returns null here is code. void LoadSettings() { // I expect to get from my app.config or settings.settings // Settings file set to application, public m_connStr = System.Configuration.ConfigurationManager.AppSettings["somestring"]; // m_connStr is getting Null. I tried .ToString(); That throws a null exception. }

  • C#: File-size format provider

    - by Seb Nilsson
    Is there any easy way to create a class that uses IFormatProvider that writes out a user-friendly file-size? public static string GetFileSizeString(string filePath) { FileInfo info = new FileInfo(@"c:\windows\notepad.exe"); long size = info.Length; string sizeString = size.ToString(FileSizeFormatProvider); // This is where the class does its magic... } It should result in strings formatted something like "2,5 MB", "3,9 GB", "670 bytes" and so on.
