  • listFiles() of File not working on symbolic links?

    - by Joset
    I have the following File object pointing to a directory via symbolic link, File directory = new File("/path/symlink/foo/bar"); String[] files = directory.listFiles(); listFiles() returns null, is this because of the symlink? if yes, how will I go about this if I really want to list the files in bar using the path that contains a symlink?

  • MediaElement fails after several plays.

    - by basilkot
    Hi! I have a problem with MediaElement control. I've put six MediaElements on my form, then I start them and change played files by timer. After several times, these elements stop playing. Here is the sample XAML: <Grid> <Grid.RowDefinitions> <RowDefinition Height="*" /> <RowDefinition Height="*" /> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition Width="*" /> <ColumnDefinition Width="*" /> <ColumnDefinition Width="*" /> </Grid.ColumnDefinitions> <MediaElement x:Name="element1" UnloadedBehavior="Close" LoadedBehavior="Manual" Grid.Column="0" Grid.Row="0" /> <MediaElement x:Name="element2" UnloadedBehavior="Close" LoadedBehavior="Manual" Grid.Column="1" Grid.Row="0" /> <MediaElement x:Name="element3" UnloadedBehavior="Close" LoadedBehavior="Manual" Grid.Column="2" Grid.Row="0" /> <MediaElement x:Name="element4" UnloadedBehavior="Close" LoadedBehavior="Manual" Grid.Column="0" Grid.Row="1" /> <MediaElement x:Name="element5" UnloadedBehavior="Close" LoadedBehavior="Manual" Grid.Column="1" Grid.Row="1" /> <MediaElement x:Name="element6" UnloadedBehavior="Close" LoadedBehavior="Manual" Grid.Column="2" Grid.Row="1" /> Here is the sample code: // The code below repeats for each MediaElement List<string> playlist1 = new List<string>() { @"file1.wmv", @"file2.wmv", @"file3.wmv", @"file4.wmv" }; DispatcherTimer timer1 = null; int index1 = 0; ... void Window1_Loaded(object sender, RoutedEventArgs e) { timer1 = new DispatcherTimer(); timer1.Tick += new EventHandler(timer1_Elapsed); timer1.Interval = TimeSpan.FromSeconds(10); element1.Source = new Uri(playlist1[index1]); timer1.Start(); element1.Play(); ... } void timer1_Elapsed(object sender, EventArgs e) { Dispatcher.BeginInvoke(DispatcherPriority.Normal, (System.Threading.ThreadStart)delegate() { element1.Stop(); element1.Close(); timer1.Stop(); index1++; if (index1 >= playlist1.Count) { index1 = 0; } element1.Source = new Uri(playlist1[index1]); timer1.Start(); element1.Play(); }); } ... Does anybody have similar problems?

  • Using Reflection.Emit to match existing constructor

    - by yodaj007
    First, here is the C# code and the disassembled IL: public class Program<T> { private List<T> _items; public Program(T x, [Microsoft.Scripting.ParamDictionary] Microsoft.Scripting.IAttributesCollection col) { _items = new List<T>(); _items.Add(x); } } Here is the IL of that constructor: .method public hidebysig specialname rtspecialname instance void .ctor(!T x, class [Microsoft.Scripting]Microsoft.Scripting.IAttributesCollection col) cil managed { .param [2] .custom instance void [Microsoft.Scripting]Microsoft.Scripting.ParamDictionaryAttribute::.ctor() = ( 01 00 00 00 ) // Code size 34 (0x22) .maxstack 8 IL_0000: ldarg.0 IL_0001: call instance void [mscorlib]System.Object::.ctor() IL_0006: nop IL_0007: nop IL_0008: ldarg.0 IL_0009: newobj instance void class [mscorlib]System.Collections.Generic.List`1<!T>::.ctor() IL_000e: stfld class [mscorlib]System.Collections.Generic.List`1<!0> class Foo.Program`1<!T>::_items IL_0013: ldarg.0 IL_0014: ldfld class [mscorlib]System.Collections.Generic.List`1<!0> class Foo.Program`1<!T>::_items IL_0019: ldarg.1 IL_001a: callvirt instance void class [mscorlib]System.Collections.Generic.List`1<!T>::Add(!0) IL_001f: nop IL_0020: nop IL_0021: ret } // end of method Program`1::.ctor I am trying to understand the IL code by emitting it myself. This is what I have managed to emit: .method public hidebysig specialname rtspecialname instance void .ctor(!T A_1, class [Microsoft.Scripting]Microsoft.Scripting.IAttributesCollection A_2) cil managed { // Code size 34 (0x22) .maxstack 4 IL_0000: ldarg.0 IL_0001: call instance void [mscorlib]System.Object::.ctor() IL_0006: ldarg.0 IL_0007: newobj instance void class [mscorlib]System.Collections.Generic.List`1<!T>::.ctor() IL_000c: stfld class [mscorlib]System.Collections.Generic.List`1<!0> class MyType<!T>::_items IL_0011: ldarg.0 IL_0012: ldfld class [mscorlib]System.Collections.Generic.List`1<!0> class MyType<!T>::_items IL_0017: ldarg.s A_1 IL_0019: nop IL_001a: nop IL_001b: nop IL_001c: callvirt instance void class [mscorlib]System.Collections.Generic.List`1<!T>::Add(!0) IL_0021: ret } // end of method MyType::.ctor There are a few differences that I just can't figure out. I'm really close... How do I take care of the parameter attribute (ParamDictionaryAttribute)? I can't find a 'custom' opcode. Is the .param [2] important? How do I emit that? Why is the C# code stack size 8, while my emitted version is 4? Is this important?

  • Refactoring method with many conditional return statements

    - by MC.
    Hi, I have a method for validation that has many conditional statements. Basically it goes If Check1 = false return false If Check2 = false return false etc FxCop complains that the cyclomatic complexity is too high. I know that it is not best practice to have return statements in the middle of functions, but at the same time the only alternative I see is an ugly list of If-else statements. What is the best way to approach this? Thanks in advance.

  • Is there a website to lookup barcodes?

    - by strange
    Hi I know there's a http://www.upcdatabase.com/ website that allows you to lookup barcodes. This website however does not return anything for thousands of normal household items. I have seen free apps on mobile phones that can do this and list the exact product name along with price comparison. Does anyone know of good websites (even commercial ones) that have a good/reliable database that one could use for lookups?

  • Queryable and BindingSource item add .net

    - by Alexander
    Hello! I wrote my own simple Queryable provider which retrieves data from a database. Now I need to bind this data to a BindingSource and when the new item is added to BindingSource some event or method must be called for handling the add operation. I have tried to implement IBingingList on a List class which is returned when the query is completed, but the AddNew method is not called when the item is added? How can I implement this scenario?

  • How to construct a flowchart/storyboard in a Func Spec

    - by PeterQ
    Hey I'm a bit embarrassed to write a post on this topic, but I would appreciate the help. At my school, the CS kids (myself included) have created a nice, little program that is built for incoming Chem/Bio students. It consists of several modules that reviews topics they should have a firm grasp on before they start their classes. It's a nice tool since it cuts down on reviewing the material in class but also allows the students to do a quick diagnostic to fix any problems. Now, I'm in charge of constructing a simple interface that reports on the progress of the group and individual students. The interface is pretty simple. It's just a window that pops up, and it has three tabs: the first tab is a "cumulative" report of all of students. The secnod tab has a drop down box that lists the students and once a student is selected, a report for him/her comes up. And the third tab is simply a description of all of the terms used in the 1st and 2nd tabs. Now, I'm trying to be a good CS student and write a func. spec for my interface. My problem comes with the fact that I'd like to insert a little flowchart using Visio. Problem is, and I'm quite embarrassed to admit this, I don't know how to construct the flowchart/storyboard. For instance, I know I start with a "Start/Click Icon" in a rectangle. Then where do I go? Do I draw three arrrows (one going to each tab) and then describing what goes on? In tab one, the only thing that happens is that the user will select a "sort" method in the drop down box. This will sort the list. The End. Similarly, if the user selects the second tab, then he will go to a drop down box with the student names. Selecting a name will bring up student info. And the third tab is just a list of unfamiliar terms coming from the first or second tab. I wanted to storyboard/flowchart what I'm doing, but I'm unclear how to go about it. Any help would be appreciated! (Just to clarify, I'm not having trouble with using Visio, but I don't know how one goes about construct a storyboard or determining the procedure for constructing one)

  • How to get Autocomplete functionality without a control

    - by rahulchandran
    If you supply a list of strings to an edit control and set the autocomplete mode and source then you automatically get autocomplete functionality. My question is can I get the same functionality in .NET somewhere without a control. In other words I want something like: string[] ProgressivePartialMatch( string[] Strings, string MatchText ) and so I want the strings back that would have showed up in the autocomplete, so to speak.

  • Python3: ssl cert information

    I have been trying to get information regarding expired ssl certificates using python 3 but it would be nice to be able to get as verbose a workup as possible. any takers? So far i have been trying to use urllib.request to get this info (to no avail), does this strike anyone as foolish? I have seen some examples of similar work using older versions of python, but nothing using v3. http://objectmix.com/python/737581-re-urllib-getting-ssl-certificate-info.html http://www.mail-archive.com/[email protected]/msg208150.html

  • Which OAuth library do you find works best for Objective-C/iPhone?

    - by Brennan
    I have been looking to switch to OAuth for my Twitter integration code and now that there is a deadline in less than 7 weeks (see countdown link) it is even more important to make the jump to OAuth. I have been doing Basic Authentication which is extremely easy. Unfortunately OAuth does not appear to be something that I would whip together in a couple of hours. http://www.countdowntooauth.com/ So I am looking to use a library. I have put together the following list. MPOAuth MGTwitterEngine OAuthConsumer I see that MPOAuth has some great features with a good deal of testing code in place but there is one big problem. It does not work. The sample iPhone project that is supposed to authenticate with Twitter causes an error which others have identified and logged as a bug. http://code.google.com/p/mpoauthconnection/issues/detail?id=29 The last code change was March 11 and this bug was filed on March 30. It has been over a month and this critical bug has not been fixed yet. So I have moved on to MGTwitterEngine. I pulled down the source code and loaded it up in Xcode. Immediately I find that there are a few dependencies and the README file does not have a clear list of steps to fetch those dependencies and integrate them with the project so that it builds successfully. I see this as a sign that the project is not mature enough for prime time. I see also that the project references 2 libraries for JSON when one should be enough. One is TouchJSON which has worked well for me so I am again discouraged from relying on this project for my applications. I did find that MGTwitterEngine makes use of OAuthConsumer which is one of many OAuth projects hosted by an OAuth project on Google Code. http://code.google.com/p/oauth/ http://code.google.com/p/oauthconsumer/wiki/UsingOAuthConsumer It looks like OAuthConsumer is a good choice at first glance. It is hosted with other OAuth libraries and has some nice documentation with it. I pulled down the code and it builds without errors but it does have many warnings. And when I run the new Build and Analyze feature in Xcode 3.2 I see 50 analyzer results. Many are marked as potential memory leaks which would likely lead to instability in any app which uses this library. It seems there is no clear winner and I have to go with something before the big Twitter OAuth deadline. Any suggestions?

  • ArrayList throwing exception on retrieval from google datastore (with gwt, java)

    - by sumeet
    I'm using Google Web Toolkit with java and google datastore as database. The entity class has arraylist and on trying to retrieve the data from data base I'm getting the exception: Type 'org.datanucleus.sco.backed.ArrayList' was not included in the set of types which can be serialized by this SerializationPolicy or its Class object could not be loaded. For security purposes, this type will not be serialized. I'm using JPA. Entity code: package com.ver2.DY.client; import java.io.Serializable; import java.util.ArrayList; import javax.jdo.annotations.IdGeneratorStrategy; import javax.jdo.annotations.PersistenceCapable; import javax.jdo.annotations.Persistent; import javax.jdo.annotations.PrimaryKey; import com.google.gwt.user.client.rpc.IsSerializable; @PersistenceCapable public class ChatInfo implements Serializable, IsSerializable{ @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) private Long topicId; @Persistent private String chatTopic; @Persistent private ArrayList messages = new ArrayList(); @Persistent private boolean isFirstPost; public ChatInfo() { } public Long getTopicId() { return topicId; } public void setTopicId(Long topicId) { this.topicId = topicId; } public String getChatTopic() { return chatTopic; } public void setChatTopic(String chatTopic) { this.chatTopic = chatTopic; } public ArrayList getMessages() { return messages; } public void addMessage(String newMsg) { messages.add(newMsg); } public boolean isFirstPost() { return isFirstPost; } public void setFirstPost(boolean isFirstPost) { this.isFirstPost = isFirstPost; } } Method in db class: @Transactional public ChatInfo[] getAllChat() { PersistenceManager pm = PMF.get().getPersistenceManager(); List chats = null; ChatInfo[] infos = null; String query = "select from " + ChatInfo.class.getName(); try{ chats = (List) pm.newQuery(query).execute(); infos = new ChatInfo[chats.size()]; for(int i=0;i } It is a bit strange because earlier I was able to insert and retrieve the data but it now throwing an exception. On searching the web I could find that I need to convert the Arraylist from some DataNucleus type to java util but not sure how to do that.
