• ASP User Control Issue

  - by Steven

  I am attempting to construct my own date picker using code from several sources. Why won't the calendar hide when visible? myDate.ascx <%@ Control Language="vb" AutoEventWireup="false" CodeBehind="myDate.ascx.vb" Inherits="Website.myDate" %> <asp:TextBox ID="dateText" runat="server" > </asp:TextBox> <asp:Button ID="dateBtn" runat="server" UseSubmitBehavior="false" Text="x" /> <asp:Calendar ID="dateCal" runat="server" ></asp:Calendar> myDate.ascx.vb Partial Public Class myDate Inherits System.Web.UI.UserControl Protected Sub dateCal_SelectionChanged(ByVal sender As Object, ByVal e As EventArgs) Handles dateCal.SelectionChanged dateText.Text = dateCal.SelectedDate ' Update text box' dateCal.Visible = False ' Hide calendar' End Sub Protected Sub dateCal_VisibleMonthChanged(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.MonthChangedEventArgs) Handles dateCal.VisibleMonthChanged dateCal.Visible = True ' For some reason, changing the month hides the calendar (so show it)' End Sub Private Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load dateCal.Visible = False ' Hide calendar on load' End Sub Protected Sub dateBtn_Click(ByVal sender As Object, ByVal e As EventArgs) Handles dateBtn.Click dateCal.Visible = Not dateCal.Visible ' On button press, toggle visibility' End Sub End Class

• Bouncy Castle, RSA : transforming keys into a String format

  - by Rami W.

  Hi, iam using RSA(Bouncy Castle API) in my c# porject. Igenerated the keypair with this method RsaKeyPairGenerator r = new RsaKeyPairGenerator(); r.Init(new KeyGenerationParameters(new SecureRandom(), 1024)); AsymmetricCipherKeyPair keys = r.GenerateKeyPair(); AsymmetricKeyParameter private_key = keys.Private; AsymmetricKeyParameter public_key = keys.Public; now i want to save them in txt file but the problem is that i can't convert them to a string format. i read in another post that keys must be serialized using PrivateKeyInfo k = PrivateKeyInfoFactory.CreatePrivateKeyInfo(private_key); byte[] serializedKey = k.ToAsn1Object().GetDerEncoded(); Is it the right way ? if yes, what should i do after this ? just convert them from byte[] to String ? thx for any help.

• Delete image file used by XAML

  - by Frode Lillerud

  I'm trying to delete a Image file in WPF, but WPF locks the file. <Image Source="C:\person.gif" x:Name="PersonImage"> <Image.ContextMenu> <ContextMenu> <MenuItem Header="Delete..." x:Name="DeletePersonImageMenuItem" Click="DeletePersonImageMenuItem_Click"/> </ContextMenu> </Image.ContextMenu> </Image> And the Click handler just looks like this: private void DeletePersonImageMenuItem_Click(object sender, RoutedEventArgs e) { System.IO.File.Delete(@"C:\person.gif"); } But, when I try to delete the file it is locked and cannot be removed. Any tips on how to delete the file?

• Implicit and Explicit implementation of interface.

  - by Amby

  While working on a upgrade i happened to come across a code like this. interface ICustomization { IMMColumnsDefinition GetColumnsDefinition(); } class Customization : ICustomization { private readonly ColumnDefinition _columnDefinition; //More code here. public ColumnsDefinition GetColumnsDefinition() { return _columnDefinition; } ColumnsDefinition ICustomization.GetColumnsDefinition() //redundant { return GetColumnsDefinition(); } } My question is: Is there any need/use of 'explicit' implementation of interface in this piece of code? Will it create any problem if i remove the method (explicit implementation of interface) that i have marked "redundant" above? PS: I understand that explicit implementation of interface is very important, and it can be used when we need to give access to a method at interface level only, and to use two interface with same signature of method.

• Jackson + Builder Pattern?

  - by Gili

  I'd like Jackson to deserialize a class with the following constructor: public Clinic(String name, Address address) Deserializing the first argument is easy. The problem is that Address is defined as: public class Address { private Address(Map<LocationType, String> components) ... public static Builder { public Builder setCity(String value); public Builder setCountry(String value); public Address create(); } } and is constructed like this: new Address.Builder().setCity("foo").setCountry("bar").create(); Is there a way to get key-value pairs from Jackson in order to construct the Address myself? Alternatively, is there a way to get Jackson to use the Builder class itself?

• Reading Binary data from a Serial Port.

  - by rross

  I previously have been reading NMEA data from a GPS via a serial port using C#. Now I'm doing something similar, but instead of GPS from a serial. I'm attempting to read a KISS Statement from a TNC. I'm using this event handler. comport.DataReceived += new SerialDataReceivedEventHandler(port_DataReceived); Here is port_DataReceived. private void port_DataReceived(object sender, SerialDataReceivedEventArgs e) { string data = comport.ReadExisting(); sBuffer = data; try { this.Invoke(new EventHandler(delegate { ProcessBuffer(sBuffer); })); } catch { } } The problem I'm having is that the method is being called several times per statement. So the ProcessBuffer method is being called with only a partial statment. How can I read the whole statement?

• will a mysql query run slower if one of the tables involved has no index defined??

  - by lock

  there's this already populated database which came from another dev im not sure what went on that dev's mind when he created the tables, but on one of our scripts there is this query involving 4 tables and it runs super slow SELECT a.col_1, a.col_2, a.col_3, a.col_4, a.col_5, a.col_6, a.col_7 FROM a, b, c, d WHERE a.id = b.id AND b.c_id = c.id AND c.id = d.c_id AND a.col_8 = '$col_8' AND d.g_id = '$g_id' AND c.private = '1' NOTE: $col_8 and $g_id are variables from a form its only my theory that it's due to tables b and c not having an index, although im guessing that the dev didnt think that it was necessary since those tables only tell relations between a and d, where b tells that the data in a belongs to a certain user, and c tells that the user belongs to a group in d as you can see, there's not even a join or other extensive query functions used but this query which returns only around 100 rows takes 2 minutes to execute. anyway my question is simply this post's title. will a mysql query run slower if one of the tables involved has no index defined??

  Hello, i've got the following question: I've got public enum Als { [StringValue("Beantwoord")] Beantwoord = 0, [StringValue("Niet beantwoord")] NietBeantwoord = 1, [StringValue("Geselecteerd")] Geselecteerd = 2, [StringValue("Niet geselecteerd")] NietGeselecteerd = 3, } with public class StringValueAttribute : System.Attribute { private string _value; public StringValueAttribute(string value) { _value = value; } public string Value { get { return _value; } } } And i would like to put the value from the item I selected of a combobox into a int: int i = ((int)(Als)Enum.Parse(typeof(Als), (string)cboAls.SelectedValue)); //<- WRONG Is this possible, and if so, how? (the stringvalue matches the value selected from the combobox) Thanks

• Spring @Autowired and WebApplicationContext in Tomcat

  - by EugeneP

  @Autowired works only once. What to do to make it wire the bean every time the Servlet is recreated? My web-app (Tomcat6 container) consists of 2 Servlets. Every servlet has private fields. Their setters are marked with @Autowired In the init method I use WebApplicationContextUtils ... autowireBean(this); It autowires the properties marked with @Autowired once - during the initialization of the Servlet. Any other session will see these fields values, they will not be rewired after the previous session is destroyed. What to do to make them rewire them each time a Servlet constructor is called? a) Put the autowiring into the constructor? Or better 2) get a web app context and extract a bean from there?

• what is the right way to exit Windoes Service OnStart if configuration is wrong and nothing to do in

  - by matti

  Is something like this ok? protected override void OnStart(string[] args) { if (SomeApp.Initialize()) { SomeApp.StartMonitorAndWork(); base.OnStart(args); } } protected override void OnStop() { SomeApp.TearDown(); base.OnStop(); } Here Initialize reads a config file and if it's wrong there's nothing to do so service should STOP! If config is ok StartMonitorAndWork starts: Timer(new TimerCallback(DoWork), null, startTime, loopTime); and DoWork polls database periodically. The question is: "Is exiting OnStart without doing nothing enough if Initialize returns false? OR should there be something like this: private void ExitService() { this.OnStop(); System.Environment.Exit(1); } protected override void OnStart(string[] args) { if (ObjectFolderApp.Initialize()) { SomeApp.StartMonitorAndWork(); base.OnStart(args); } else { ExitService(); } } Thanks & BR - Matti

• Progress Dialog in Android doesn't Show?

  - by Tyler

  Okay.. I am doing something similar to the below: private void onCreate() { final ProgressDialog dialog = ProgressDialog.show(this, "Please wait..", "Doing stuff..", true); Thread t = new Thread() { public void run() { //do some serious stuff... dialog.dismiss(); } }; t.start(); t.join(); stepTwo(); } However, what I am finding is that my progress dialog never even shows up. My App stalls for a moment so I know it is chugging along inside of thread t, but why doesnt my dialog appear? IF I remove the line: t.join(); Then what I find happens is that the progress dialog does show up, but my app starts stepTwo(); before what happens in the thread is complete.. Any ideas?

• How to automize multiple projects build process by including digital signature of exe in Delphi?

  - by user193655

  After building a project group of 2 projects with Delphi (2009) I digitally sign the 2 exes using InstallAware Code signing, an exe that shipped with Delphi 2009. How is it possible to automize the digital signature, so when I build I can also attach digital signature. For digital signing I use a pvk (private key) file and an spc (Sw publisher certificate) file. Subquestion: Moreover I created a project group because I have 2 exes, but they are almost the same, the only thing that changes is the Application icon and the application name (one is ProductOne.dpr, the other is ProductTwo.dpr). In practice I have 2 brands of the same product, I have a single build but activation keys details activate one or the other, anyway now I was asked to change the icon and the filename, and for this I need to build 2 projects, activation key is not enough anymore to distinguish between the 2. Anyway if there is a way to do this from a single project it would be better.

• Using TortoiseHg to push to an authenticated git repository

  - by Nathan Palmer

  I'm trying to push a changeset from a local Mercurial repository created with TortoiseHg to a remote Git repository. I have hg-git installed and configured and it will pull just fine. But when I run the push it gives me this Command hg push git+ssh://git@dummyrepo:username/repo.git Result pushing to git+ssh://git@dummyrepo:username/repo.git importing Hg objects into Git creating and sending data abort: the remote end hung up unexpectedly There are several things I've done to get to this point. But I'm hoping to resolve this last thing because I find TortoiseHg to be much easier to work with than any of the Git tools out there (for windows.) Installed TortoiseHg Pulled down the hg-git from http://bitbucket.org/durin42/hg-git/ Configured mercurial.ini to point to the hg-git library Pulled down dulwich source from git://git.samba.org/jelmer/dulwich.git Compiled dulwich and put it into library.zip for TortoiseHg Configured TortoiseHg to use TortoisePlink.exe for ssh Added my private key to Pageant Any ideas what I could be missing?

• What languages, preprocessors, and toolkits will Apple not allow you to develop iPhone OS 4.0 Apps w

  - by Tony Lambert

  According to articles on web Apple will not approve Apps that have code that is not originally developed in Objective C, C or C++. Found on the Web: 3.3.1 Applications may only use Documented APIs in the manner prescribed by Apple and must not use or call any private APIs. Applications must be originally written in Objective-C, C, C++, or JavaScript as executed by the iPhone OS WebKit engine, and only code written in C, C++, and Objective-C may compile and directly link against the Documented APIs (e.g., Applications that link to Documented APIs through an intermediary translation or compatibility layer or tool are prohibited). Can we build a list of things developer use that will and won't be allowed under these possible new rules? We can use: C, C++, Objective C We can't use: Flash, Monotouch C#, Pascal, Fortran, Perl, Python, Lex, Yacc, Unity (games engine), Java What others?

• Downloading a file in ASP.NET (through the server) while streaming it to the user

  - by James Teare

  My ASP.NET website currently downloads a file from a remote server to a local drive, although when users access the site they have to wait for the server to finish downloading the file until they can then download the file from my ASP.NET website. Is it possible to almost stream the download from the remote website - through my ASP.NET website directly to the user (a bit like a proxy) ? My current code is as follows: using (var client = new WebClientEx()) { client.DownloadFile(downloadURL, "outputfile.zip"); } WebClient class: public class WebClientEx : WebClient { public CookieContainer CookieContainer { get; private set; } public WebClientEx() { CookieContainer = new CookieContainer(); } protected override WebRequest GetWebRequest(Uri address) { var request = base.GetWebRequest(address); if (request is HttpWebRequest) { (request as HttpWebRequest).CookieContainer = CookieContainer; } return request; } }

• Proper way to set object instance variables

  - by ensnare

  I'm writing a class to insert users into a database, and before I get too far in, I just want to make sure that my OO approach is clean: class User(object): def setName(self,name): #Do sanity checks on name self._name = name def setPassword(self,password): #Check password length > 6 characters #Encrypt to md5 self._password = password def commit(self): #Commit to database >>u = User() >>u.setName('Jason Martinez') >>u.setPassword('linebreak') >>u.commit() Is this the right approach? Should I declare class variables up top? Should I use a _ in front of all the class variables to make them private? Thanks for helping out.

• Retrieve Google Calendar Events

  - by Don

  Hi, I'm using the Java API for Google Calendar. The documents show the following example of how to retrieve events from a calendar: URL feedUrl = new URL("http://www.google.com/calendar/feeds/[email protected]/private/full"); CalendarService myService = new CalendarService("exampleCo-exampleApp-1"); myService.setUserCredentials("[email protected]", "mypassword"); // Send the request and receive the response: CalendarEventFeed myFeed = myService.getFeed(feedUrl, CalendarEventFeed.class); This will retrieve all events from the primary calendar of the [email protected] account. However, I need to retrieve events from a secondary calendar. I already have a reference the CalendarEntry object that represents the secondary calendar, but I still can't figure out how to get events from it. I suspect I can do this using the same code as above, but I just need to change the URL to something else. Thanks, Donal

• How do I solve an unresolved external when using C++ Builder packages (with TForm based classes)?

  - by José Renato

  Hi, i'm working with Bulder C++ 6 and 2010, and i'm having this problem: http://stackoverflow.com/questions/2727001/how-do-i-solve-an-unresolved-external-when-using-c-builder-packages But, the difference here is that i'm using a FORM compiled inside the package, so, take the example above, but in addition i'm including a form classe, like TForm2: class TForm2 : public TForm { __published: // IDE-managed Components TButton *Button1; void __fastcall Button1Click(TObject *Sender); private: // User declarations public: // User declarations __fastcall TForm2(TComponent* Owner); }; //--------------------------------------------------------------------------- extern PACKAGE TForm2 *Form2; //--------------------------------------------------------------------------- So, when i'm trying to use this class in any project the linker stops and give me the unresolved external error. When i got that error i tried to include the word PACKAGE, like this: class PACKAGE TForm2 But, when i tried to compile the PACKAGE, the compiler stops with the unresolved external error: [ILINK32 Error] Error: Unresolved external '__fastcall Forms::TCustomForm::~TCustomForm()' referenced from c:\projects\UNIT2.OBJ How can i solve this problem? PS.: Sorry about the bad English.

• Spring constructor injection of SLF4J logger - how to get injection target class?

  - by disown

  I'm trying to use Spring to inject a SLF4J logger into a class like so: @Component public class Example { private final Logger logger; @Autowired public Example(final Logger logger) { this.logger = logger; } } I've found the FactoryBean class, which I've implemented. But the problem is that I cannot get any information about the injection target: public class LoggingFactoryBean implements FactoryBean<Logger> { @Override public Class<?> getObjectType() { return Logger.class; } @Override public boolean isSingleton() { return false; } @Override public Logger getObject() throws Exception { return LoggerFactory.getLogger(/* how do I get a hold of the target class (Example.class) here? */); } } Is FactoryBean even the right way to go? When using picocontainers factory injection, you get the Type of the target passed in. In guice it is a bit trickier. But how do you accomplish this in Spring?

• What's wrong with my cross-thread call in Windows Forms?

  - by MainMa

  Hi, I encounter a problem with a Windows Forms application. A form must be displayed from another thread. So in the form class, I have the following code: private delegate void DisplayDialogCallback(); public void DisplayDialog() { if (this.InvokeRequired) { this.Invoke(new DisplayDialogCallback(DisplayDialog)); } else { this.ShowDialog(); } } Now, every time I run this, an InvalidOperationException is thrown on the line this.ShowDialog();: "Cross-thread operation not valid: Control 'SampleForm' accessed from a thread other than the thread it was created on." What's wrong with this piece of code? Isn't it a valid way to make cross-thread calls? Is there something special with ShowDialog()?

• Integrate openid4java to GWT Project

  - by Slyker

  Hi, I created an GWT project in eclipse. Now I tried to implement openId with using the openid4java library. I imported the .jar files via properties--java build path: openid4java-0.9.5.jar lib/*.jar In addition I copied the .jar files into the war/WEB-INF/lib directory. The problem at hand comes up when I call the authenticate() method. Then I get a: HTTP ERROR 500 Problem accessing /openid/openid.
