• IE7 left:%; bug

  - by YuriKolovsky

  I'm working on a project, I use the latest IETester, and I bumped into a IE7 specific alignment bug. view this in IE7 and then in any other browser, for example Firefox, IE8 and even IE6. Notice how the little "|" between the lower links is not visible in IE7, yet it looks fine in the other browsers. Removing the left:-100%; from on line 61 fixes the bug as seen here, but i need this "left" for positioning. Any help on what is causing this bug, or potential ideas on how to fix it much needed.

• How to build a java applet?

  - by Stefano Borini

  Most of the tutorials around explain how to create a java applet: create a .java file with a class, compile it with javac, put the .class somewhere, add a proper tag in the html. However, I'm not able to find anything about the best practices to build and release a complex applet, made of multiple classes and with additional libraries. How is the build/release process for this case ? What is it needed to go from my java project to the final .jar to put on the web ? I'm working with pure Eclipse, no plugins.

• Flex - Is there a way to change the "Channel Disconnected" error message?

  - by Travesty3

  I have a Flash app with a PHP backend. Whenever there is a PHP error, I get the "Channel Disconnected before an acknowledgement was received" error message. I'm getting ready to push my project to beta and I would prefer if this message said something more like "There was a PHP error, please log a bug" or something instead of a message they don't understand. Anyone know of a way for me to change this error message? BTW I'm pretty much a noob when it comes to Flash programming so please be descriptive. Using Flash Builder 4 Beta 2.

• entity framework, loadproperty not working - The selector expression for LoadProperty must be a Memb

  - by SLC

  The selector expression for LoadProperty must be a MemberAccess for the property. I'm converting some C# to VB, this is the C# line: entities.LoadProperty((MyType)MyTargetObject, c => c.MyProperty); I convert it to VB like so: entities.LoadProperty(DirectCast(MyTargetObject, MyType), Function(c) c.MyProperty) However I get the error above. I don't understand what the code is doing, or anything at all, I am simply converting it line by line into Visual Basic. When I run the project, the error I get is the one above. All I can see is that Entities is a class that inherits ObjectContext, which might mean something. Any help would be soooo good because I am stressing out big time. Thanks.

• SSRS 2008 Installation Guidelines/Best Practices?

  - by Brad Bowman

  I know I have seen recommendations for installing SSRS 2005 and it stated that you should separate SSRS from the DB Engine that hosts the data sources for your reports, that you should not install them on the same server. Is there any documentation for SSRS 2008 that provides guidelines/best practices for installation? I am assuming that the same holds true for SSRS 2008 as it did for SSRS 2005 but have not seen it specifically stated anywhere. We have a project that will utilize SSRS 2008 and there is a difference of opinion on where to install it, on it's own dedicated server or on the same SQL Server as the report data sources. If there is a link to any documentation that could be provided it would be gratefully appreciated, all I am finding besides what is in BOL refers to 2005. Thanks in advance!

• 2D collision detection and stuff with OpenGL

  - by shinjuo

  I am working on a simple 2D openGL project. It contains a main actor you can control with the keyboard arrows. I got that to work okay. What I am wanting is something that can help explain how to make another actor object follow the main actor. Maybe a tutorial on openGL. The three main things I need to learn are the actor following, collision detection, and some kind of way to create gravity. Any good books or tutorials to help get me in the right direction would be great.

• jQuery .Ajax() function selector , store specific data in variable

  - by user279321

  I am new to jQuery and I have the following problem. My project has say 2 pages, 1.JSP and 2.html. Now I want to pick selected data from 2.html and use it on 1.JSP. Now this was achieved very easily using .load but I want the data to be present in a JavaScript variable rather than put it on the page (div tags, etc.), so that I can work upon that data (modify or add to database). I tried using .ajax and was able to write the following code: var value = (function () { var val = nulll; var filename = " 2.html"; $.ajax ({ 'async': false, 'global': false, 'url': filename, 'success' : function(data) { val = data; } }) return val; })() document.write(value) Where do I put the selector format (say div.id5) so that my variable have only relevant data rather than the full file data?

• JavaScript frameworks and CSS frameworks: JQuery, YUI, neither, or something else?

  - by Eric Johnson

  I haven't done web development for about 6 years. I'm trying to get back into it and there is a lot of new stuff out there. I've chosen to write my next project with Perl and Catalyst. I keep hearing about various JavaScript and CSS frameworks. I know very little about these frameworks so maybe this question is overly broad and open ended. What are the strengths, weaknesses, and popularity of the various frameworks? Should I be using YUI, JQuery, neither, or something else?

• Asp.NET 1.1 HttpResponse headers

  - by Yeti

  Hi, i have part of Asp.NET 1.1 project. I work with remote site, which works incorrect in some cases - sometimes it write incorrect Content-Encoding header. In my code i get HttpResponse from this remote site. And if Content-Encoding header is equals, for example, "gzip", i need to set Content-Encoding header to "deflate". But there is no properties or methods in HttpResponse class to get Content-Encoding header. Content-Encoding property returns, in my case, "UTF-8". In Watch window i see _customProperties field, which contain wrong string value. How can i change header value with Asp.NET 1.1?

• Windows Forms Autosizing in .NET

  - by mcoolbeth

  My C# project contains a form. There are some controls across the top of the form and some controls across the bottom of the form, as well as a FlowLayoutPanel in the center, all of which have been placed with the Visual Studio Form Designer. During runtime, controls are dynamically added to and removed from the FlowLayoutPanel, and both the panel and the form itself are configured to automatically fit the size of they're contents. However, since some controls were placed with the designer above and below the FlowLayoutPanel, the desired resizing fails to take place when new controls are added to the FlowLayoutPanel. Does anybody know of a convenient remedy for this problem?

• Combine master-detail databinding

  - by clawson

  I have created data sources from my objects in my project, some of which have other objects as members. When I want to bind a some objects to a data grid I would like to display some of the values from the member objects in the data grid as well but the examples I have come across seem to use an entire other datagrid or controls to display these member object values. How can I combine these values into one data grid? (Preferably without creating a wrapping class) Can I achieve this with LINQ somehow? Your help is greatly appreciated. Thanks P.S. C# or VB examples will do.

• scvmap, disco, xsd, wsdl, svcinfo and datasource files

  - by David Gray Wright

  We have a WEb Service named, let's say Foo. So there is a Foo.svc file and a code behind Foo.svc.cs. We add a silverlight project and wish to use the Foo.svc services so we add a Service Reference and call it's namespace FooBar. This creates the following files : Reference.cs Reference.svcmap Foo.xsd Foo.disco configuration.svcinfo Foo.wsdl Also various *.datasource files. Over time we update the Foo.svc and add more Web Services (methods and interfaces) and the number of files in the FooBar directory is growing. I have 26 Foo(nn).xsd files in this directory - where nn = 1 to 26. My configuration.svcinfo is upto configuration91.svcinfo. My question is this? Do any of these files need to be version controlled? Can they all be deleted each time you do a build \ deploy (as long as you do an update service reference)?

• Django BigInteger auto-increment field as primary key?

  - by Alex Letoosh

  Hi all, I'm currently building a project which involves a lot of collective intelligence. Every user visiting the web site gets created a unique profile and their data is later used to calculate best matches for themselves and other users. By default, Django creates an INT(11) id field to handle models primary keys. I'm concerned with this being overflown very quickly (i.e. ~2.4b devices visiting the page without prior cookie set up). How can I change it to be represented as BIGINT in MySQL and long() inside Django itself? I've found I could do the following (http://docs.djangoproject.com/en/dev/ref/models/fields/#bigintegerfield): class MyProfile(models.Model): id = BigIntegerField(primary_key=True) But is there a way to make it autoincrement, like usual id fields? Additionally, can I make it unsigned so that I get more space to fill in? Thanks!

• How to configure SQLite db in Visual Studio

  - by ChrisC

  I've messed with Access a little bit in the past, had one class on OO theory, and one class on console c++ apps. Now, as a hobby project, I'm undertaking to write an actual app, which will be a database app using System.Data.SQLite and C#. I have the db's table structure planned. I have System.Data.SQLite installed and connected to VS Pro. I entered my tables and columns in VS, but that's where I'm stuck. I really don't know how to finish the db set up so I can start creating queries and testing the db structure. Can someone give me guidance to online resources that will help me learn how to get the db properly set up so I can proceed with testing it? I'm hoping for online resources specific to beginners using C# and System.Data.SQLite, but I'll use the closest I can get. Thanks.

• ASP.NET MVC TDD with LINQ and SQL database

  - by dean nolan

  I am trying to start a new MVC project with tests and I thought the best way to go would have 2 databases. 1 for testing against and 1 for when I run the app and use it (also test really as it's not production yet). For the test database I was thinking of putting create table scripts and fill data scripts within the test setup method and then deleting all this in the tear down method. I am going to be using Linq to SQL though and I don't think that will allow me to do this? Will I have to just go the ADO route if I want to do it this way? Or should I just use a mock object and store data as an array or something?. Any tips on best practices? How did Jeff go about doing this for StackOveflow?

• Which language/framework to use for this desktop internet application?

  - by Karsten

  I'd like to experiment with a new language/framework to work on some desktop tools for myself, which will do tasks related to internet services. I.e. i'd like to to monitor some of my servers for http or icmp response, also parse xml responses. I have experience with php, lua, mysql, and basic knowledge of java and c++. I'm also interested in exploring multithreading for this, background tasks and a responsive gui do need that as i have read. Being a private project, i certainly want to learn something new, but i don't have that much free time. The question for you would be which language and what framework to choose that could help me with this tasks: lightweight + fast gui (windows only would be ok, platform-independent even better) network/socket support, html module would be appreciated htmlview support xml "parsing" support (xpath or something like the phpish DOMDocument class) threading support Free software would be nice, but paying some bucks won't hurt me if it really helps the case.

• Why doesn't .NET find the OpenSSL.NET dll?

  - by Lazlo

  EDIT (the whole question, it was too unclear) I want to use OpenSSL.NET The OpenSSL.NET install instructions page: INSTALL Make sure you have libeay32.dll and ssleay32.dll in the current working directory of your application or in your PATH. DONE In your .NET project, add a reference to the ManagedOpenSsl.dll assembly. DONE I have put libeay32.dll and ssleay32.dll in both my bin/Debug and bin/Release directories. I have also put them in system32. Here is my FULL code: using System; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { try { OpenSSL.Crypto.RSA rsa = new OpenSSL.Crypto.RSA(); } catch (Exception e) { Console.WriteLine(e.InnerException.Message); } Console.Read(); } } } I get the following error: (Unable to load DLL 'libeay32') Here is the Process Monitor log (upon request): What am I doing wrong? Why isn't the DLL found?

• Projecting a 3D point to 2D screen coordinate OpenTK

  - by sinsro

  Using Monotouch and OpenTK I am trying to get the screen coordinate of one 3D point. I have my world view projection matrix set up, and OpenGL makes sense of it and projects my 3D model perfectly, but how to use the same matrix to project just one point from 2D to 3D? I thought I could simply use: Vector3.Transform(ref input3Dpos, ref matWorldViewProjection, out projected2Dpos); Then have the projected screen coordinate in projected2DPos. But the resulting Vector4 does not seem to represent the proper projected screen coordinate. And I do not know how to calculate it from there on.

• What is a good git server frontend for self hosted git repositories

  - by Ritesh M Nayak

  I am planning on deploying git for a project I am currently working on and was wondering if there are any free softwares that provide an easy to use web view of the git repository. I am primarily interested in using the front end to track changes, see diff information etc. There is a list of such front ends available here. Does anyone have any experience with any of these ? Which one would you suggest An open source clone of github would do just fine actually :D but I know thats too much to ask .

• iPhone Simulator chrashes in NSKeyedUnarchiver after setting base SDK

  - by Florian

  Hi! I started a project in xcode (3.2 on snow leopard) with base sdk 3.1.2. Now I changed this setting to 3.0 and it compiles without a warning. There are no problems running the app on the device, but the simulator crashes on launch every time with the following exception: Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '[NSKeyedUnarchiver initForReadingWithData:]: incomprehensible archive (0x4e, 0x49, 0x42, 0x41, 0x72, 0x63, 0x68, 0x69)' I do not use the NSKeyedUnarchiver, so why is the app trying to call it? And what archive is incomprehensible? I reset the simulator before building, so there are no userDefaults or anything else around. Thanks for your help!

• C# Monte Carlo Simulation Package Needed

  - by Yunzhou

  I'm relative new to C# and doing a project using Monte Carlo Simulation. Basically my question is the following. I have two uncertain variable inputs, A and B, and they will go through a model and give an output C. So C = f(A,B). I know A's probability distribution (Triangular) and B's probability distribution (Discrete). How can I get the probability distribution of C? What I have done now is that I can generate random numbers based on A's triangular distribution as well as B's discrete distribution. Each pair of randomly generated A and B gives a resultant C. I've run this model 1000 times thus I can get 1000 possible values of C. The difficulty is to get the corresponding probabilities of each value of C. Obviously it's not 1/1000 unless C is uniformly distributed. Is there any Monte Carlo Simulation package/library I can use?

• Ideas on collaborating with small number of people

  - by Mark Szymanski

  Hi, I am collaborating with someone on a project and currently use Skype for collaboration. I like it because we can be on a call to say things that are hard to say by typing out. We can share our screens so we can help with code writing. And we can use the text chat to copy-paste code between each other. We also use Subversion for version control. I just wanted to know what other people used for collaborating with others so I could see whats out there to use. Thanks!

• Django ImageField validation & PIL

  - by Zayatzz

  Hello On sunday, I had problems with python modules, when I installed stackless python. Now I have compiled and installed : setuptools & python-mysqldb and i got my django project up and running again. (i also reinstalled django-1.1), Then I compiled and installed, jpeg, freetype2 and PIL. I also started using mod_wsgi instead of mod_python. But when uploading imagefield in form I get validationerror: Upload a valid image. The file you uploaded was either not an image or a corrupted image. Searchmonkey shows that it comes from field.py imagefield validation. before raising this error it imports Image from PIL, opens file and verfies it. I tried importing PIL from python prompt manually - it worked just fine. Same with Image.open and Image.verify. So what could be causing this problem? Alan
