  • Visual C# GUI Designer basic tutorial

    - by cusack
    Hi, can you recommend a Visual C# Form Designer tutorial that is targeted at experienced programmers who have at least a basic knowledge of C# but are new to the VS C# Form Designer. At least it shouldn't be targeted at programming newbs, like Introduction to Visual C# 2008 Express Edition (it explains how a comment looks like in C#). So far I've found C# Programming Tutorial - Programming Winforms in C# on stackoverflow. Wishlist: ;-) I'm more interested in focus on the designer itself rather than an explanation of single gui-elements. In other words explaining separation between generated-code, what to not edit manually (visual-c#-designer-responsibility) and on the other hand the parts for which the programmer himself is responsible. So a little more abstract best-practice point of view pointing out some caveats would be great as well. I would prefer text over video as well, but that's minor. /Wishlist Perhaps even a Microsoft reference specific to the Visual c# forms designer (which I seem to have been unable to find) would be helpful.

  • Is there a Maven plugin to generate AS3 classes from Java for BlazeDS ?

    - by Maskime
    Hi, I'm looking for a maven plugin that would generate ActionScript3 classes from Java classes in order to access them by object remoting. I've seen FlexMojo but it uses the GraniteDS generator wich create some problems when it comes to map Enum objects (wich can be fix through a workaround that is describe here : http://dev.c-ware.de/confluence/display/PUBLIC/Flexmojos+generated+AS3+model+with+Enum+support+using+BlazeDS?focusedCommentId=7634946&#comment-7634946 if you've googled your way here this might be useful) when working with BlazeDS. Everything that i found so far are people who explain how to generate VO classes on flex side using Flash Builder 4, but this solution can not be used in an industrial developpement environnement. Thanks in advance for any leads on this matter.

  • FIFA official website design and development

    - by Morron
    Hi, I'm just curious about design and development of official FIFA website. What is the programming language being used to build the site? What is the development methodology they are using? I used Firebug to look around the site.Here's sth I found: HTTP/1.1 200 OK Cache-Control: no-store, no-cache, must-revalidate, private Content-Type: text/html Server: Microsoft-IIS/7.0 x-ua-compatible: IE=EmulateIE7 Vary: Accept-Encoding Content-Length: 8320 Date: Tue, 15 Jun 2010 17:54:19 GMT Connection: keep-alive According to that, I think they use IIS 7 to run the site but I'm not sure what programming language they are using. Any comment is a drop of water in the glass.

  • Building Visual studio like application, need inputs..

    - by akjoshi
    Hi, I am working on a Visual studio like application i.e. hava a tolbox, an editor and property grid similar to VS. ser can drag and drop the controls(custom and third party) to the editor window and perform operations like resize, move, align, group etc.; Properties of that control needs to be displayed in property grid and user can update them from there. As per my current understanding I will have to extend the Canvas to create my own editor and and Interface for controls which it supports; Each supported control will have to implemnt this interface so that it can be placed in our editor. Something similar to this - http://www.codeproject.com/KB/WPF/WPFDiagramDesigner_Part4.aspx Looking forward for any kind of help, comment or links.

  • Problem with persisting inteface collection at design time in winforms, .net

    - by Jules
    The easiest way to explain this problem is to show you some code: Public Interface IAmAnnoyed End Interface Public Class IAmAnnoyedCollection Inherits ObjectModel.Collection(Of IAmAnnoyed) End Class Public Class Anger Implements IAmAnnoyed End Class Public Class MyButton Inherits Button Private _Annoyance As IAmAnnoyedCollection <DesignerSerializationVisibility(DesignerSerializationVisibility.Content)> _ Public ReadOnly Property Annoyance() As IAmAnnoyedCollection Get Return _Annoyance End Get End Property Private _InternalAnger As Anger <DesignerSerializationVisibility(DesignerSerializationVisibility.Content)> _ Public ReadOnly Property InternalAnger() As Anger Get Return Me._InternalAnger End Get End Property Public Sub New() Me._Annoyance = New IAmAnnoyedCollection Me._InternalAnger = New Anger Me._Annoyance.Add(Me._InternalAnger) End Sub End Class And this is the code that the designer generates: Private Sub InitializeComponent() Dim Anger1 As Anger = New Anger Me.MyButton1 = New MyButton ' 'MyButton1 ' Me.MyButton1.Annoyance.Add(Anger1) // Should be: Me.MyButton1.Annoyance.Add(Me.MyButton1.InternalAnger) ' 'Form1 ' Me.Controls.Add(Me.MyButton1) End Sub I've added a comment to the above to show how the code should have been generated. Now, if I dispense with the interface and just have a collection of Anger, then it persists correctly. Any ideas?

  • What are the differences among sqlite3 from python2.5, pysqlite and apsw

    - by leo
    Hi, I would like to know the differences among sqlite3 from python2.5, pysqlite and apsw? I have a bumpy run when trying to install pysqlite on windows vista with python2.5, see following: download sqlite from http://sqlite.org/download.html and unzip them into windows/system32 folder and put sqlite3.dll into c:/python25/Lib folder download pysqlite windows installer when trying to run following in python shell: >>> from pysqlite2 import test Traceback (most recent call last): File "<stdin>", line 1, in <module> File "pysqlite2\test\__init__.py", line 35, in <module> from pysqlite2.test import dbapi, types, userfunctions, factory, transactions,\ File "pysqlite2\test\dbapi.py", line 27, in <module> import pysqlite2.dbapi2 as sqlite File "pysqlite2\dbapi2.py", line 27, in <module> from pysqlite2._sqlite import * ImportError: No module named _sqlite I am wondering anybody with experiences of the above three types of sqlite binding to python can comment their pros and cons such as performances I am wondering is it worthwhile to try the pysqlite or apsw thanks

  • Are there any code libraries that validate/convert blog comments to XHTML strict?

    - by Matthew James Taylor
    I am working on a website in PHP where people can make comments similar to a blog, and I only want particular tags to be allowed. Are there any pre-built libraries that process comments and produce valid XHTML Strict code? I would need to do this in JavaScript so I can generate a live preview like Stack Overflow, plus in PHP before saving it to a MySQL database. The allowed HTML tags will be: strong, em, blockquote, and links (rel=nofollow not required) One way would be to allow people to directly enter the HTML into the comment field but I would prefer to use a simple mark up something like this (can be different - this is an example): *strong* _em_ [blockquote] http://www.link.com I want line breaks to be converted to <br />. Are there any code libraries that do the above?

  • Advantages of Thread pooling in embedded systems

    - by Microkernel
    I am looking at the advantages of threadpooling design pattern in Embedded systems. I have listed few advantages, please go through them, comment and please suggest any other possible advantages that I am missing. Scalability in systems like ucos-2 where there is limit on number of threads. Increasing capability of any task when necessary like Garbage collection (say in normal systems if garbage collection is running under one task, its not possible to speed it up, but in threadpooling we can easily speed it up). Can set limit on the max system load. Please suggest if I am missing anything.

  • White (Light) vs. Black (Dark) Backgrounds: Health Effects

    - by Hosam Aly
    I am adding a bounty to this question, hoping for some scientific research results. Thank you everybody! I have recently tried working on dark backgrounds, and it seemed (to me) to be easier on the eye. However, today I read Gerrie Schenck's comment on this answer, in which he said that mainframe developers were advised to use white backgrounds instead of black, as it is said that white is easier on the eye. So which one is actually better for the eyes in the long run? I would be thankful for any (scientific) references about the subject, as my eyes really need some relaxation. I wanted to make this question a community wiki, but I think that the least I can do to thank people is to reward their answers, so I'm leaving it as a normal question. Many, many thanks for your help. P.S. I don't know which tags would be appropriate for this question, so I'd be grateful if you could tag it in a better way than I did.

  • Innodb setting in xampp doesn't seem locate my.cnf file....

    - by bala3569
    I created a new mysql database and i want to use foreign keys with it... I googled and found out this... InnoDB is one of MySQL storage engines, it supports transactions, row-level locking, and foreign-keys. However, by default, InnoDB is not enabled by XAMPP. To enable it, locate the my.cnf configuration file (normally in C:/xampp/mysql/bin directory) and search for the following lines: # Comment the following if you are using InnoDB tables But the path C:/xampp/mysql/bin directory in my system doesn't seem to have such a file... Look at this image http://img691.imageshack.us/img691/524/mysqln.jpg Where is my.cnf file? Any suggestion...

  • in TFS can we customize the merge algorithm (conflict resolution)

    - by Jennifer Zouak
    In our case we want to igonore changes in code comment headers for generated code. In Visual Studio, we can change the merge tool (GUI that pops up) and use a 3rd party tool that is able to be customized to ignore changes (http://msdn.microsoft.com/en-us/library/ms181446.aspx). Great, so a file comparison no longer highlights code comments as differences. However when it comes time to checkin, the TFS merge algorith is still prompting us to resolve conflicts. Is there any way to better inform the merge conflict resolution algorithm about which changes are actually important to us? Or can we replace the algorithm or otherwise have it subcontract its work to a 3rd party?

  • Software to create a knowledge base/FAQ system

    - by H1Man
    Our company is looking to build a web-based knowledge base system that can be used by our clients/end users to reduce the amount of support calls. Couple important notes: This is aimed at our end users, in other words, non-techies. So the UI has to be easy to use Should have the excellent (fast, accurate) search Should have ability to rate and comment on articles This will only be maintained by one or 2 people, so security isn't a big concern Something similar to what Microsoft is doing with their Knowledge Base. http://support.microsoft.com/search/ Does anyone have any recommendations on what software I can use? Thanks, H. Edit: I should have made this clear before but I don't mean build as in having our developers build a support/kb system from the ground up. I am looking to use a existing software package/solution that can be used to implement a knowledge base/support site.

My wishes are: by 'distrib' I mean: plugins, settings & preferences... be able to use the same eclipse setup in several workstations MAYBE sharing with other members of the team works across 3.5 and next 3.6: I don't know if it's possible. And anyway I would not object to customize the distrib once per new eclipse major release

  • Embedding QT application in Eclipse/RCP framework

    - by mots_g
    Hi, I'm trying to embed my working QT application in Eclipse RCP framework(might not sound wise but i need to do this). I'm using QT 4.5 (not yet explored what QTJambi is all about and has to offer) I convert my existing application as a dll and load it through eclipse application. Things dont work as they should as the QTApplication loop sits listening for events, and there is a good mismatch of events. Certain UI objects dont get the events. If I comment my Qppliaction::exec(), then the behaviour in QT app changes. Is there a way to achieve what I'm trying to achieve?? Thanks

  • Why does DataSet.HasChanges() return true if called in the same function as change but false otherwi

    - by Chapso
    Assuming that the buttons are being clicked in order, the following code modifies row 1 in a .net DataSet, then row 0. HasChanges returns true, but GetChanges only gives me the change for row 0. If I comment out the line in the button2 click event that modifies row 0, then HasChanges returns false. Can anyone explain to me why HasChanges() and GetChanges() only return true when they are called in the same function as the change to the DataSet? Protected Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click __ds1.Tables(0).Rows(1)("EmployeeName") = "TestStuff" End Sub Protected Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click __ds1.Tables(0).Rows(0)("EmployeeName") = "TestStuff" If __ds1.HasChanges(DataRowState.Modified Or DataRowState.Added) Then __ds2 = __ds1.GetChanges(DataRowState.Modified _ Or DataRowState.Added) GridView3.DataSource = __ds2.Tables("Users").DefaultView GridView3.DataBind() Else End If End Sub

  • Mutex names - best practice?

    - by Argalatyr
    Related to this question, what is the best practice for naming a mutex? I realize this may vary with OS and even with version (esp for Windows), so please specify platform in answering. My interest is in Win XP and Vista. EDIT: I am motivated by curiousity, because in Rob Kennedy's comment under his (excellent) Answer to the above-linked Question, he implied that the choice of mutex name is non-trivial and should be the subject of a separate question. EDIT2: The referenced question's goal was to ensure only a single instance of an app is running.

  • Limitations in running Ruby/Rails on windows

    - by johnc
    In the installation documentation to RoR it mentions that there are many limitations to running Ruby on Rails on Windows, and in some cases, whole libraries do not work. How bad are these limitations, should I always default to Linux to code / run RoR, and is Iron Ruby expected to fix these limitations or are they core to the OS itself? EDIT Thanks for the answer around installation and running on Linux, but I am really trying to understand the limitations in functionality as referenced in the installation documentation, and non-working libraries - I am trying to find a link to the comment, but it was referenced in an installation read me when I installed the msi package I think

  • Specify an inline callback function as an argument.

    - by Matthias Vance
    LS, Let me first explain what I'm trying to achieve using some pseudo-code (JavaScript). // Declare our function that takes a callback as as an argument, and calls the callback with true. B(func) { func(true); } // Call the function B(function(bool success) { /* code that uses success */ }); I hope this says it all. If not, please comment on my question so I can write a little more to clarify my issue. What I want is to have code like this in C++. I have tried to use lambda functions, but I was unable to specify a parameter type for those. Kind regards, Matthias Vance

  • Mibble MIB Parser - extracting comments from the mib.

    - by this.matt
    I am using the Mibble MIB Parser to extract all simple data types from an MIB file. I've been successful until my attempt to extract comment text. Take the following module as an example: invBookList OBJECT-TYPE SYNTAX INTEGER { mobydick(1), -- call me ishmael paradiselost(2), -- aComment 1984(3), -- aComment solaris(4) -- aComment } MAX-ACCESS read-only STATUS current DESCRIPTION "A few Books for an example." ::= { invMasterList 43 } According to Mibble's API, the OBJECT-TYPE can be accessed by extracting an SnmpObjectType and then calling the appropriate getter method. Which I have done, and can successfully extract all of the text except the comments in the INTEGER syntax. I have tried calling getSyntax().getComment() on the SnmpObjectType, but always returns null. getSyntax() will extract the INTEGER syntax, e.g.: mobydick(1),paradiselist(2),1984(3),solaris(4) but unfortunately strips out the comments. Any one out there have experience with Mibble Parser who knows how to extract the comments? Many Thanks.

  • Backbone.js not registering Model.hasChanged event

    - by Brian M. Hunt
    Hello, I'm trying to get a View in Backbone.js to save when there's a 'change' event if (and only if) the data has changed. Long story short, I've a 'change' event set on the View that calls this: function changed_event() { log.debug("Before: " + this.model.get('name')) // not 'contrived!' this.model.set({'name': 'contrived!'}); log.debug("After: " + this.model.get('name')) // 'contrived!' if (this.model.hasChanged()) { alert("This is never called."); } } I'd like to know why the model.hasChanged() is false when clearly the model has been changed. I'm not sure what other information is necessary, but if there is more information that may be helpful please comment and I'll elaborate. Thank you for reading.
