  • ASP.NET MVC routing issue with Google Chrome client

    - by synergetic
    My Silverlight 4 app is hosted in ASP.NET MVC 2 web application. It works fine when I browse with Internet Explorer 8. However Google Chrome (version 5) cannot find ASP.NET controllers. Specifically, the following ASP.NET controller works both with Chrome and IE. //[OutputCache(NoStore = true, Duration = 0, VaryByParam = "None")] public ContentResult TestMe() { ContentResult result = new ContentResult(); XElement response = new XElement("SvrResponse", new XElement("Data", "my data")); result.Content = response.ToString(); return result; } If I uncomment [OutputCache] attribute then it works with IE but not with Chrome. Also, I use custom model binding with controllers, so if I write the following: public ContentResult TestMe(UserContext userContext) { ... } it also works with IE, but again not with Chrome which gives me error message saying that resource was not found. Of course, I configured IIS 6 for handling all requests via aspnet_isapi.dll and I have registered custom model binder in my web app's Global.asax inside Application_Start() method. Can someone explain me what might be the cause? Thank you.

  • How to use log4j for a axis2 webservice

    - by KItis
    I have created a simple axis2 webservice to understand logging functionality in a webservice. in this sample webservice, when a client calls this webservice, first it reads the log4j.property file. then i can see the logs being printed on console. but i have included file appender too into the property file. but i can not file the log file any where in my sample webapplication. i am using tomcat to run the webservice. following is webservice interface method called by client. package test; import java.io.IOException; import java.io.InputStream; import java.util.Properties; import org.apache.log4j.BasicConfigurator; import org.apache.log4j.Logger; import org.apache.log4j.PropertyConfigurator; public class WSInterface { static final Logger logger = Logger.getLogger(WSInterface.class); public String log4jTest(String input){ InputStream inputStream = this.getClass().getClassLoader() .getResourceAsStream(input); Properties properties = new Properties(); System.out.println("InputStream is: " + inputStream); //load the inputStream using the Properties try { properties.load(inputStream); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } PropertyConfigurator.configure(properties); logger.debug("Hello World!"); Class myclass = WSInterface.class; String url = myclass.getResource("WSInterface.class").toString(); String output = ""; return url; } }

  • ASP.NET MVC: Returning a view with querystring intact

    - by ajbeaven
    I'm creating a messaging web app in ASP.NET and are having some problems when displaying an error message to the user if they go to send a message and there is something wrong. A user can look through profiles of people and then click, 'send a message'. The following action is called (url is /message/create?to=username) and shows them a page where they can enter their message and send it: public ActionResult Create(string to) { ViewData["recipientUsername"] = to; return View(); } On the page that is displayed, the username is entered in to a hidden input field. When the user clicks 'send': [AcceptVerbs(HttpVerbs.Post)] public ActionResult Create(FormCollection collection, string message) { try { //do message stuff that errors out } catch { ModelState.AddModelErrors(message.GetRuleViolations()); //adding errors to modelstate } return View(); } So now the error message is displayed to the user fine, however the url is changed in that it no longer has the querystring (/message/create). Again, this would be fine except that when the user clicks the refresh button, the page errors out as the Create action no longer has the 'to' parameter. So I'm guessing that I need to maintain my querystring somehow. Is there any way to do this or do I need to use a different method altogether?

  • How can "today's date" be varied for unit testing purposes?

    - by ck
    I use VS2008 targetting .NET 2.0 Framework, and, just in case, no I can't change this :) I have a DateCalculator class. Its method GetNextExpirationDate attempts to determine the next expiration, internally using DateTime.Today as a baseline date. As I was writing unit tests, I realized that I wanted to test GetNextExpirationDate for different 'today' dates. What's the best way to do this? Here are some alternatives I've considered: Expose a property/overloaded method with argument baselineDate and only use it from the unit test. In actual client code, disregard the property/overloaded method in favour of the method that defaults baselineDate to DateTime.Today. I'm reluctant to do this as it makes the public interface of the DateCalculator class awkward. Create a protected field called baselineDate that is internally set to DateTime.Today. When testing, derive a DateCalculatorForTesting from DateCalculator and set baslineDate via the constructor. It keeps the public interface clean, but still isn't great - baselineDate was made protected and a derived class is required, both solely for testing. Use extension methods. I tried this after adding the ExtensionAttribute, then realized it wouldn't work because extension methods can't access private/protected variables. I initially thought this was really quite an elegant solution. :( I'd be interested in hearing what others think.

  • How to Avoid PHP Object Nesting/Creation Limit?

    - by Will Shaver
    I've got a handmade ORM in PHP that seems to be bumping up against an object limit and causing php to crash. Here's a simple script that will cause crashes: <? class Bob { protected $parent; public function Bob($parent) { $this->parent = $parent; } public function __toString() { if($this->parent) return (string) "x " . $this->parent; return "top"; } } $bobs = array(); for($i = 1; $i < 40000; $i++) { $bobs[] = new Bob($bobs[$1 -1]); } ?> Even running this from the command line will cause issues. Some boxes take more than 40,000 objects. I've tried it on Linux/Appache (fail) but my app runs on IIS/FastCGI. On FastCGI this causes the famous "The FastCGI process exited unexpectedly" error. Obviously 20k objects is a bit high, but it crashes with far fewer objects if they have data and nested complexity. Fast CGI isn't the issue - I've tried running it from the command line. I've tried setting the memory to something really high - 6,000MB and to something really low - 24MB. If I set it low enough I'll get the "allocated memory size xxx bytes exhausted" error. I'm thinking that it has to do with the number of functions that are called - some kind of nesting prevention. I didn't think that my ORM's nesting was that complicated but perhaps it is. I've got some pretty clear cases where if I load just ONE more object it dies, but loads in under 3 seconds if it works.

  • Boost lambda: Invoke method on object

    - by ckarras
    I'm looking at boost::lambda as a way to to make a generic algorithm that can work with any "getter" method of any class. The algorithm is used to detect duplicate values of a property, and I would like for it to work for any property of any class. In C#, I would do something like this: class Dummy { public String GetId() ... public String GetName() ... } IEnumerable<String> FindNonUniqueValues<ClassT> (Func<ClassT,String> propertyGetter) { ... } Example use of the method: var duplicateIds = FindNonUniqueValues<Dummy>(d => d.GetId()); var duplicateNames = FindNonUniqueValues<Dummy>(d => d.GetName()); I can get the for "any class" part to work, using either interfaces or template methods, but have not found yet how to make the "for any method" part work. Is there a way to do something similar to the "d = d.GetId()" lambda in C++ (either with or without Boost)? Alternative, more C++ian solutions to make the algorithm generic are welcome too. I'm using C++/CLI with VS2008, so I can't use C++0x lambdas.

  • zend framework controller not found ?

  • Add Ellipsis to a Path in a WinForms Program without Win32 API call (revisited)

    - by casterle
    I was searching for a way to insert an ellipsis in a C# path, and found an answer here on stackoverflow: http://tinyurl.com/y6rmdfr Using the RTM versions of VS2010 and .Net 4.0, I was unable to get the suggested method to work. I searched the 'Net and found example code that uses the same method, but it failed in the same way. You can see the string I'm trying to shorten in my code below. After calling the MeasureText method, both the input string (OriginalName) and the output string (ellipsisedName) look like this: d:\abcd\efgh\ijkl\mnop\qrst\...\test.txt\0F\GHIJ\KLMN\OPQR\STIV\WXYZ\test.txt Two problems: 1) The resulting string is narfed (the path is truncated as expected, but is followed by what looks like a C-style terminating null and a chunk of the original path). 2) My original string is changed to be identical to the output string. Am I doing something wrong? namespace WindowsFormsApplication2 { public partial class Form1 : Form { public Form1() { InitializeComponent(); string OriginalPath = @"d:\abcd\efgh\ijkl\mnop\qrst\uvwx\yzAB\CDEF\GHIJ\KLMN\OPQR\STIV\WXYZ\test.txt"; string ellipsisedPath = OriginalPath; Size proposedSize = new Size(label1.Width, label1.Height); TextRenderer.MeasureText(ellipsisedPath, label1.Font, proposedSize, TextFormatFlags.ModifyString | TextFormatFlags.PathEllipsis); } } }

  • Return an empty collection when Linq where returns nothing

    - by ahsteele
    I am using the below statement with the intent of getting all of the machine objects from the MachineList collection (type IEnumerable) that have a MachineStatus of i. The MachineList collection will not always contain machines with a status of i. At times when no machines have a MachineStatus of i I'd like to return an empty collection. My call to ActiveMachines (which is used first) works but InactiveMachines does not. public IEnumerable<Machine> ActiveMachines { get { return Customer.MachineList .Where(m => m.MachineStatus == "a"); } } public IEnumerable<Machine> InactiveMachines { get { return Customer.MachineList .Where(m => m.MachineStatus == "i"); } } Edit Upon further examination it appears that any enumeration of MachineList will cause subsequent enumerations of MachineList to throw an exeception: Object reference not set to an instance of an object. Therefore, it doesn't matter if a call is made to ActiveMachines or InactiveMachines as its an issue with the MachineList collection. This is especially troubling because I can break calls to MachineList simply by enumerating it in a Watch before it is called in code. At its lowest level MachineList implements NHibernate.IQuery being returned as an IEnumerable. What's causing MachineList to lose its contents after an initial enumeration?

  • ASP.NET MVC Posted date field comes in as 1/1/0001

    - by engil
    Just started working with .NET and MVC(1). I'm having a problem wherein in my add action the entered date for some reason ends up as 1/1/0001 instead of what is entered thus causing a date overflow. In my model, this field ("Added") is is of type datetime and does not allow nulls. In my controller I have: public ActionResult Add() { Instance instance = new Instance() { Added = DateTime.Now, Active = true }; return View(instance); } [AcceptVerbs(HttpVerbs.Post)] public ActionResult Add(Instance instance) { if (ModelState.IsValid) { try { System.Diagnostics.Trace.Write("test"); instanceRepository.Add(instance); instanceRepository.Save(); return RedirectToAction("Details", new { id = instance.InstanceID }); } catch { ModelState.AddRuleViolations(instance.GetRuleViolations()); } } return View(instance); } And in my view I have: <div class="editor-label"> <%= Html.LabelFor(model => model.Added) %> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.Added,String.Format("{0:g}",Model.Added))%> <%= Html.ValidationMessageFor(model => model.Added) %> When I first go to Instances/Add the default value is set correctly, however as soon as I submit the date turns into 1/1/0001 (from my understanding this indicates that it was either null or in an unrecognizable format) When I debug and palce a watch on Request.Form I see the date coming in encoded ie Request.Form {Added=4%2f9%2f2010+8%3a24%3a39+AM} - is this an issue? I know its probably not enough information to make a conlusive determination on why this is failing, but if someone could provide some good debugging tips on how to determine where the submitted date is getting munged I'd really appreciate it.

  • Am I using Settings in .NET correctly?

    - by Sergio Tapia
    Here's what I'm doing. I have three properties: MomsBackground, DadsBackground and ChosenBackground. When Momsbackground is selected in the program, I set the ChosenBackground string according to what item the user has clicked (either "Mom" or "Dad"). Then on Form_Load() I use a switch case for the ChosenBackground string and according to that select This.BackgroundColor to MomsBackground or DadsBackground. Code below: Am I using this as it was intended? Sorry, codes there now. using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; namespace WindowsFormsApplication1 { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void momToolStripMenuItem_Click(object sender, EventArgs e) { this.BackColor = Properties.Settings.Default.MomFormColor; Properties.Settings.Default.SelectedTheme = "Mom"; Properties.Settings.Default.Save(); } private void dadToolStripMenuItem_Click(object sender, EventArgs e) { this.BackColor = Properties.Settings.Default.DadFormColor; Properties.Settings.Default.SelectedTheme = "Dad"; Properties.Settings.Default.Save(); } private void Form1_Load(object sender, EventArgs e) { switch (Properties.Settings.Default.SelectedTheme) { case "Mom": this.BackColor = Properties.Settings.Default.MomFormColor; break; case "Dad": this.BackColor = Properties.Settings.Default.DadFormColor; break; default: break; } } } }

  • Mono WCF NetTcp service takes only one client at a time

    - by vene
    While trying to build a client-server WCF application in Mono we ran into some issues. Reducing it to just a bare example we found that the service only accepts one client at a time. If another client attempts to connect, it hangs until the first one disconnects. Simply changing to BasicHttpBinding fixes it but we need NetTcpBinding for duplex communication. Also the problem does not appear if compiled under MS .NET. EDIT: I doubt (and hope not) that Mono doesn't support what I'm trying to do. Mono code usually throws NotImplementedExceptions in such cases as far as I noticed. I am using Mono v2.6.4 This is how the service is opened in our basic scenario: public static void Main (string[] args) { var binding = new NetTcpBinding (); binding.Security.Mode = SecurityMode.None; var address = new Uri ("net.tcp://localhost:8080"); var host = new ServiceHost (typeof(Hello)); host.AddServiceEndpoint (typeof(IHello), binding, address); ServiceThrottlingBehavior behavior = new ServiceThrottlingBehavior () { MaxConcurrentCalls = 100, MaxConcurrentSessions = 100, MaxConcurrentInstances = 100 }; host.Description.Behaviors.Add (behavior); host.Open (); Console.ReadLine (); host.Close (); } The client channel is obtained like this: var binding = new NetTcpBinding (); binding.Security.Mode = SecurityMode.None; var address = new EndpointAddress ("net.tcp://localhost:8080/"); var client = new ChannelFactory<IHello> (binding, address).CreateChannel (); As far as I know this is a Simplex connection, isn't it? The contract is simply: [ServiceContract] public interface IHello { [OperationContract] string Greet (string name); } Service implementation has no ServiceModel tags or attributes. I'll update with details as required.

  • onTouchListener togglebutton, ignores first press?

    - by Paul
    I have a togglebutton that should run code when I press it down and more code when I let go. However the first time I press and let go nothing happens. Every other time it is fine, why is this? I can see the method only runs the first time when I let go of the button (it does not trigger any onTouch part of the method though), how can I get around this, and have it work for the first press? public void pushtotalk3(final View view) { ((ToggleButton) view).setChecked(true); ((ToggleButton) view).setChecked(false); view.setOnTouchListener(new OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { //if more than one call, change this code int callId = 0; for (SipCallSession callInfo : callsInfo) { callId = callInfo.getCallId(); Log.e(TAG, "" + callInfo.getCallId()); } final int id = callId; switch (event.getAction()) { case MotionEvent.ACTION_DOWN: { //press ((ToggleButton) view).setBackgroundResource(R.drawable.btn_blue_glossy); ((ToggleButton) view).setChecked(true); OnDtmf(id, 17, 10); OnDtmf(id, 16, 9); return true; } case MotionEvent.ACTION_UP: { //release ((ToggleButton) view).setBackgroundResource(R.drawable.btn_lightblue_glossy); ((ToggleButton) view).setChecked(false); OnDtmf(id, 18, 11); OnDtmf(id, 18, 11); return true; } default: return false; } } }); } EDIT: the xml for the button: <ToggleButton android:id="@+id/PTT_button5" android:layout_width="0dp" android:layout_height="fill_parent" android:text="@string/ptt5" android:onClick="pushtotalk5" android:layout_weight="50" android:textOn="Push To Talk On" android:textOff="Push To Talk Off" android:background="@drawable/btn_lightblue_glossy" android:textColor="@android:color/white" android:textSize="15sp" /> EDIT: hardware problem, can't test solutions atm.

  • Inner join and outer join options in Entity Framework 4.0

    - by bigb
    I am using EF 4.0 and I need to implement query with one inner join and with N outer joins I started to implement this using different approaches but get into trouble at some point. Here is two examples how I started of doing this using ObjectQuery<'T' and Linq to Entity 1)Using ObjectQuery<'T' I implement flexible outer join but I don't know how to perform inner join with entity Rules in that case (by default Include("Rules") doing outer join, but i need to inner join by Id). public static IEnumerable<Race> GetRace(List<string> includes, DateTime date) { IRepository repository = new Repository(new BEntities()); ObjectQuery<Race> result = (ObjectQuery<Race>)repository.AsQueryable<Race>(); //perform outer joins with related entities if (includes != null) foreach (string include in includes) result = result.Include(include); //here i need inner join insteard of default outer join result = result.Include("Rules"); return result.ToList(); } 2)Using Linq To Entity I need to have kind of outer join(somethin like in GetRace()) where i may pass a List with entities to include) and also i need to perform correct inner join with entity Rules public static IEnumerable<Race> GetRace2(List<string> includes, DateTime date) { IRepository repository = new Repository(new BEntities()); IEnumerable<Race> result = from o in repository.AsQueryable<Race>() from b in o.RaceBetRules select new { o }); //I need here: // 1. to perform the same way inner joins with related entities like with ObjectQuery above //here i getting List<AnonymousType> which i cant cast to //IEnumerable<Race> when i did try to cast like //(IEnumerable<Race>)result.ToList(); i did get error: //Unable to cast object of type //'System.Collections.Generic.List`1[<>f__AnonymousType0`1[BetsTipster.Entity.Tip.Types.Race]]' //to type //'System.Collections.Generic.IEnumerable`1[BetsTipster.Entity.Tip.Types.Race]'. return result.ToList(); } May be someone have some ideas about that.

  • Open the Word Application from a button on a web page

    - by Andrea
    I'm developing a proof of concept web application: A web page with a button that opens the Word Application installed on the user's PC. I'm stuck with a C# project in Visual Studio 2008 Express (Windows XP client, LAMP server). I've followed the Writing an ActiveX Control in .NET tutorial and after some tuning it worked fine. Then I added my button for opening Word. The problem is that I can reference the Microsoft.Office.Interop.Word from the project, but I'm not able to access it from the web page. The error says "That assembly does not allow partially trusted callers". I've read a lot about security in .NET, but I'm totally lost now. Disclaimer: I'm into .NET since 4 days ago. I've tried to work around this issue but I cannot see the light!! I don't even know if it will ever be possible! using System; using System.Collections.Generic; using System.ComponentModel; using System.Drawing; using System.Data; using System.Linq; using System.Text; using System.Windows.Forms; using Word = Microsoft.Office.Interop.Word; using System.IO; using System.Security.Permissions; using System.Security; [assembly: AllowPartiallyTrustedCallers] namespace OfficeAutomation { public partial class UserControl1 : UserControl { public UserControl1() { InitializeComponent(); } private void openWord_Click(object sender, EventArgs e) { try { Word.Application Word_App = null; Word_App = new Word.Application(); Word_App.Visible = true; } catch (Exception exc) { MessageBox.Show("Can't open Word application (" + exc.ToString() + ")"); } } } }

  • Keep Hibernate Initializer from Crashing Program

    - by manyxcxi
    I have a Java program using a basic Hibernate session factory. I had an issue with a hibernate hbm.xml mapping file and it crashed my program even though I had the getSessionFactory() call in a try catch try { session = SessionFactoryUtil.getSessionFactory().openStatelessSession(); session.beginTransaction(); rh = getRunHistoryEntry(session); if(rh == null) { throw new Exception("No run history information found in the database for run id " + runId_ + "!"); } } catch(Exception ex) { logger.error("Error initializing hibernate"); } It still manages to break out of this try/catch and crash the main thread. How do I keep it from doing this? The main issue is I have a bunch of cleanup commands that NEED to be run before the main thread shuts down and need to be able to guarantee that even after a failure it still cleans up and goes down somewhat gracefully. The session factory looks like this: public class SessionFactoryUtil { private static final SessionFactory sessionFactory; static { try { // Create the SessionFactory from hibernate.cfg.xml sessionFactory = new Configuration().configure().buildSessionFactory(); } catch (Throwable ex) { // Make sure you log the exception, as it might be swallowed System.err.println("Initial SessionFactory creation failed." + ex); throw new ExceptionInInitializerError(ex); } } public static SessionFactory getSessionFactory() { try { return sessionFactory; } catch(Exception ex) { return null; } } }

  • Is there any Java Decompiler that can correctly decompile calls to overloaded methods?

    - by mihi
    Consider this (IMHO simple) example: public class DecompilerTest { public static void main(String[] args) { Object s1 = "The", s2 = "answer"; doPrint((Object) "You should know:"); for (int i = 0; i < 2; i++) { doPrint(s1); doPrint(s2); s1 = "is"; s2 = new Integer(42); } System.out.println(); } private static void doPrint(String s1) { System.out.print("Wrong!"); } private static void doPrint(Object s1) { System.out.print(s1 + " "); } } Compile it with source/target level 1.1 without debug information (i.e. no local variable information should be present) and try to decompile it. I tried Jad, JD-GUI and Fernflower, and all of them got at least one of the call wrong (i. e. the program printed "Wrong!" at least once) Is there really no java decompiler that can infer the right casts so that it will not call the wrong overload?

  • Hibernate query for multiple items in a collection

    - by aarestad
    I have a data model that looks something like this: public class Item { private List<ItemAttribute> attributes; // other stuff } public class ItemAttribute { private String name; private String value; } (this obviously simplifies away a lot of the extraneous stuff) What I want to do is create a query to ask for all Items with one OR MORE particular attributes, ideally joined with arbitrary ANDs and ORs. Right now I'm keeping it simple and just trying to implement the AND case. In pseudo-SQL (or pseudo-HQL if you would), it would be something like: select all items where attributes contains(ItemAttribute(name="foo1", value="bar1")) AND attributes contains(ItemAttribute(name="foo2", value="bar2")) The examples in the Hibernate docs didn't seem to address this particular use case, but it seems like a fairly common one. The disjunction case would also be useful, especially so I could specify a list of possible values, i.e. where attributes contains(ItemAttribute(name="foo", value="bar1")) OR attributes contains(ItemAttribute(name="foo", value="bar2")) -- etc. Here's an example that works OK for a single attribute: return getSession().createCriteria(Item.class) .createAlias("itemAttributes", "ia") .add(Restrictions.conjunction() .add(Restrictions.eq("ia.name", "foo")) .add(Restrictions.eq("ia.attributeValue", "bar"))) .list(); Learning how to do this would go a long ways towards expanding my understanding of Hibernate's potential. :)

    I have an application that uses MKMapView and at some point in the app I need to remove all the current pins in the map using [mapView removeAnnotations:mapView.annotations] And then I want to show again the current user location mapView.showUserLocation = YES But I can only make it reappear as a regular pin, because the userLocation view class its not public so I cant return views of that type. Here is my code - (MKAnnotationView *)mapView:(MKMapView *)theMapView viewForAnnotation:(id <MKAnnotation>)annotation MKPinAnnotationView* annView = (MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:@"currentloc"]; if (!annView) { MKPinAnnotationView *annView=[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"currentloc"]; annView.pinColor = MKPinAnnotationColorRed; annView.animatesDrop=TRUE; annView.canShowCallout = YES; annView.calloutOffset = CGPointMake(-5, 5); if ([annotation isKindOfClass:[DraggableAnnotationAM class]] ) annView.draggable = YES; return annView; } else { if ([annotation isKindOfClass:[DraggableAnnotationAM class]] ) annView.draggable = YES; annView.annotation = annotation; return annView; } Also I have found through reflection that MKUserLocationView is the class that is used to display the current location, but because its not public its not safe to use and my app keeps crashing and Im sure theres a easier way. Is it possible to do what I want, or should I just never remove the user location annotation of the mapView? Thanks in advance

  • How do i pass arbitary date format from C# to sql backend

    - by Jims
    I have a datetime field for the transaction date in the back end. So I am passing that date from front C#.net, in the below format: 2011-01-01 12:17:51.967 to do this I have written: presentation layer: string date = DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss.fff", CultureInfo.InvariantCulture); PropertyClass prp=new PropertyClass(); Prp.TransDate=Convert.ToDateTime(date); PropertyClass structure: Public class property { private DateTime transdate; public DateTime TransDate { get { return transdate; } set { transdate = value; } } } From DAL layer passing the TransactionDate like this: Cmd.Parameters.AddWithValue("@TranSactionDate”, SqlDbType.DateTime).value=propertyobj.TransDate; While debugging from presntation layer: string date = DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss.fff", CultureInfo.InvariantCulture); in this I am getting correct expected date format, but when debugs goes to this line Prp.TransDate=Convert.ToDateTime(date); again date format changing to 1/1/2011. But my backend sql datefield wants the date paramter 2011-01-01 12:17:51.967 in this format otherwise throwing exception invalid date format. Note: While passing date as string without converting to datetime getting exceptions like: System.Data.SqlTypes.SqlTypeException: SqlDateTime overflow. Must be between 1/1/1753 12:00:00 AM and 12/31/9999 11:59:59 PM. at System.Data.SqlTypes.SqlDateTime.FromTimeSpan(TimeSpan value) at System.Data.SqlTypes.SqlDateTime.FromDateTime(DateTime value) at System.Data.SqlTypes.SqlDateTime..ctor(DateTime value) at System.Data.SqlClient.MetaType.FromDateTime(DateTime dateTime, Byte cb) at System.Data.SqlClient.TdsParser.WriteValue(Object value, MetaType type, Byte scale, Int32 actualLength, Int32 encodingByteSize, Int32 offset, TdsParserStateObject stateObj) at System.Data.SqlClient.TdsParser.TdsExecuteRPC(_SqlRPC[] rpcArray, Int32 timeout, Boolean inSchema, SqlNotificationRequest notificationRequest, TdsParserStateObject stateObj, Boolean isCommandProc)

  • Paypal Encrypted Website payments

    - by John Isaacks
    I am trying to integrate a PayPal Website Payments Standard Cart Upload payment type into my shopping cart. I integrated Google Checkout a while back and I did not find it overly confusing as I do paypal. I am getting info on how to encrypt it from here: https://cms.paypal.com/us/cgi-bin/?&cmd=_render-content&content_ID=developer/e_howto_html_encryptedwebpayments#id08A3I0P017Q Paypal says I need to generate a private key and a public certificate using OpenSSL. I went to OpenSSL and downloaded the latest release, which is just a folder containing various files but I see no application I can use, not sure what to do here. Even if I were to get OpenSSL to generate me a private key and public cert, the next step is to download either an MS or Java command line tool to create the encrypted cart ahead of time with the cart-total, tax, etc. which sounds crazy to me, like I am supposed to manually do this prior to every order?? Obviously I do not know the items in the cart the customer is going to buy before hand so I need this to be done on the fly on my website using PHP. But I am completely lost. There has to be a way to setup dynamic secure cart uploads to paypal. Can someone please point me in the right direction?
