• Close button during modal sheet

  - by Nano8Blazex

  In Objective C (Cocoa) I have an app running with a modal sheet, but I want to allow the app to quit even when the sheet is displayed (contradicting the definition of modal I think, but I like the animated effect of modal sheets). I'm already using the -setPreventsApplicationTerminationWhenModal method and it works fine, but I'm wondering... is there any way to keep the close button enabled? The little circle usually red-colored close button that comes with all windows in the top left corner (side by side with minimize and maximize)? Right now it's completely disabled when the sheet is running, and it would be awesome if there is a way to enable it. Thanks!

• Comparing tables with filtering in different databases and visualizing diffs/pushing changes

  - by MicMit

  I am building certain GUI in C# for a content manager and looking for the tools or code snippets or open libraries ( code ideally in C# ) which allow me the following : 1. For table A in database X (test ) and table A in database Y (production) and for a simple filter ( e.g. listname = "XYZ" ) I need to show additions/deletions/updates in some way. which might be side-by-side or just 2 record added table with some fields 2 record deleted table with some fields Considering that this task is very common, I guess, certain components should exist ? Components either return some collections from parameters given for further visualizing or just produce for e.g. html report. 2. I need to push changes for the filter I mentioned in 1 and update table in production database for this filter only ( ie for the particular list approved by content person). Again probably there are certain SQL code generators - components in addition to diffs or standalone.

• In MVC2, how do I validate fields that aren't in my data model?

  - by Andy Evans

  I am playing with MVC2 in VS 2010 and am really getting to like it. In a sandbox application that I've started from scratch, my database is represented in an ADO.NET entity data model and have done much of the validation for fields in my data model using Scott Guthrie's "buddy class" approach which has worked very well. However, in a user registration form that I have designed and am experimenting with, I'd like to add a 'confirm email address' or a 'confirm password' field. Since these fields obviously wouldn't exist in my data model, how would I validate these fields client side and server side? I would like to implement something like 'Html.ValidationMessageFor', but these fields don't exist in the data model. Any help would be greatly appreciated.

• When does IE7 recompute styles? Doesn't work reliably when a class is added to the body.

  - by Kid A

  I have an interesting problem here. I'm using a class on the element as a switch to drive a fair amount of layout behavior on my site. If the class is applied, certain things happen, and if the class isn't applied, they don't happen. The relevant CSS is roughly like this: .rightSide { display:none; } .showCommentsRight .rightSide { display:block; width:50%; } .showCommentsRight .leftSide { display:block; width:50%; } And the HTML: <body class="showCommentsRight"> <div class="container"></div> <div class="leftSide"></div> <div class="rightSide"></div> </div> <div class="container"></div> <div class="leftSide"></div> <div class="rightSide"></div> </div> <div class="container"></div> <div class="leftSide"></div> <div class="rightSide"></div> </div> </body> I've simplified things but this is essentially the method. The whole page changes layout (hiding the right side in three different areas) when the flag is set on the body. This works in Firefox and IE8. It does not work in IE8 in compatibility mode. What is fascinating is that if you sit there and refresh the page, the results can vary. It will pick a different section's right side to show. Sometimes it will show only the top section's right side, sometimes it will show the middle. I have tried a validator (to look for malformed html), double css formatting, and making sure my IE7 hack sheet wasn't having an effect. So my question is: * Is there a way that this behavior can be made reliable? * When does IE7 decide to re-do styling? Thanks everyone.

• XSL-stylesheet URI using JAX-WS and Glassfish v3.

  - by Tony

  Hi there. I'm trying to use XSL-stylesheets in order to transform some generated XML-data to HTML-output. The architecture that I'm using is as follows: [Client Side] Web-Browser = [Server Side: Glassfish v3] JSP-pages - Web-Services. My web service generates some XML-data, then I want to format it with XSL-stylesheet, pass the result to JSP-page and show to user. I'm using JAXP for XSL-transformations and I want to create a javax.xml.transform.stream.StreamSource object with XSL-file stream for the javax.xml.transform.Transformer object, but I'm having a difficulty with specifying the path/URL for the XSL-file. So the question is: where should I put my XSL-stylesheets in a project and how should I access them from code? I'm using Glassfish v3 and NetBeans 6.8. Thanks.

• SVN Mac oSX issue - permissions?

  - by Steve Griff

  Hello there, /Volumes/sites is a connection to a samba share that hosts some of our sites. We authorise using a username & password that is the same user/pass to log onto the mac. When committing, (or even doing a cleanup) from the Mac Client side using the svn command line tool or SCPlugin, this error occurs: Commit succeeded, but other errors follow: Error bumping revisions post-commit (details follow): In directory '/Volumes/sites/foobar/public_html' Error processing command 'committed' in '/Volumes/sites/foobar/public_html' Error replacing text-base of 'index.php' Can't move '/Volumes/sites/foobar/public_html/.svn/tmp/text-base/index.php.svn-base' to '/Volumes/sites/foobar/public_html/.svn/text-base/index.php.svn-base': Operation not permitted Any ideas? I think it's to do with permissions on the mac side not being able to move files around on the samba share. Apologies if my question is kinda vague so any extra information I can give please shout. Regards Steve

• How do I repeat part of an image using background-position and CSS sprites?

  - by thor

  I would like to create some buttons with dynamic width using CSS sprites and background-position but I'm not sure if what I want is possible.. I would like the button to have a left-side, middle, and right-side, with the middle repeating as required. Ideally I would like this to be made up of one image of 11px wide so the left and right sides are both 5px wide and the middle is 1px repeated. Is there some way I can define in CSS to use the one centre pixel of the image and repeat if for the required (unknown) width? Normally I've used two images to achieve similar results - one for the sides and a second image of 1px width for the middle, but if there's some way of combining them into one image I would prefer to use that.

• Using a .Net Workstation Program With a LAMP Server

  - by Brian

  Hi, I am currently working on a project for a company with a Ubuntu LAMP server set up. All the workstations are on Windows XP/Vista. What we are trying to do is create a program to track parts in our warehouse. Server side would be programmed in PHP. However, I was thinking about using C# on the workstation side. Is this possible? If so, is this practical? What kind of problems could arise from something like this?

• Multiple key/value pairs in HTTP POST where key is the same name

  - by randombits

  I'm working on an API that accepts data from remote clients, some of which where the key in an HTTP POST almost functions as an array. In english what this means is say I have a resource on my server called "class". A class in this sense, is the type a student sits in and a teacher educates in. When the user submits an HTTP POST to create a new class for their application, a lot of the key value pairs look like: student_name: Bob Smith student_name: Jane Smith student_name: Chris Smith What's the best way to handle this on both the client side (let's say the client is cURL or ActiveResource, whatever..) and what's a decent way of handling this on the server-side if my server is a Ruby on Rails app? Need a way to allow for multiple keys with the same name and without any namespace clashing or loss of data.

• Whats the best way to stop this app crash when buttons rapidly pressed iphone obj-c

  - by dubbeat

  Hi, I'm not entirely sure why this crash is happening and I'd like to get advice on the best way to deal with it. My app has 3 buttons. Each button requests a different XML file from a server which is used to populate a table view. If I rapidly press the buttons in sequence , button 1 button 2 button3 button 1 button 2 button3 button 1 button 2 button3 the application quits. What could be causing this. Would id be in the NSURLRequest side of things or the table view population side? How would you suggest I stop this behaviour? I was going to just set a boolean "isRequesting" to true when a button is pressed and set it to false when the table view is finished populating. If any button is pressed while isRequesting is True they do nothing. Does that sound wise or is there a better way? Thanks, dub

• Ajax based progress bar

  - by Punit

  I am developing a progress bar using Ajax. My client side code is working fine, but I have issue at server side. I am using C based CGI. if(i == inc && pb_inc<=100) { fptr = fopen("progress_bar.txt", "w"); fprintf(fptr,"%d", j); fclose(fptr); pb_inc++; } basically I am increasing progress bar after certain number of bytes. What I see here is that the CGI doesn't let display any data to text file until it has sent all the data to file one by one. i have referred to http://www.redips.net/javascript/ajax-progress-bar/ Any idea whats happening here?

• How to change out-of-focus text selection color in Xcode?

  - by Jackson

  Okay, I'll bite. I've got really pleasant code/window colors set up in Xcode. Ordinarily, my selection color is very visible. When I am doing a project search and iterating through the results, however, the results list stays in focus and the found text remains out of focus, using a different background color. This color is extremely hard to detect, especially when the text is embedded in a larger code block and the view is shifting around as it scrolls to the results. Here's an example: Left side is in focus (just normal selection), right side is out of focus (during project find) Often it takes a few seconds to find where the heck the selected text is. Unless I'm just missing it, Xcode seems to offer no way to change this particular selection color. Interestingly, it also doesn't seem to follow the selection color from the Appearance panel. Does anyone know a way to change this color or force it to be more visible, short of changing my entire color scheme around?

• Can I encrypt value in C# and use that with SQL Server 2005 symmetric encryption?

  - by Robert Byrne

  To be more specific, if I create a symmetric key with a specific KEY_SOURCE and ALGORITHM (as described here), is there any way that I can set up the same key and algorithm in C# so that I can encrypt data in code, but have that data decrypted by the symmetric key in Sql Server? From the research I've done so far, it seems that the IDENTITY_VALUE for the key is also baked into the cypher text, making things even more complex. I'm thinking about just trying all the various ways I can think of, ie hashing the KEY_SOURCE using different hash algorithms for a key and trying different ways of encrypting the plain text until I get something that works. Or is that just futile? Has anyone else done this, any pointers? UPDATE Just to clarify, I want to use NHibernate on the client side, but theres a bunch of stored procedures on the database side that still perform decryption.

• Peak decomposition

  - by midtiby

  Hi I want to examine a NMR spectre and make the best fit of a specific peak using a sum of gaussians. With the following code it is possible to fit two gaussians to the peak, but can it easily be generalized to n gaussians? freq <- seq(100, 200, 0.1) signal <- 3.5*exp(-(freq-130)^2/50) + 0.2 + 1.5*exp(-(freq-120)^2/10) simsignal <- rpois(length(signal), 100*signal) + rnorm(length(signal)) plot(freq, simsignal) res <- nls(simsignal ~ bg + h1 * exp(-((freq - m1)/s1)^2) + h2 * exp(-((freq - m2)/s2)^2), start=c(bg = 4, h1 = 300, m1 = 128, s1 = 6, h2 = 200, m2 = 122, s2 = 4), trace=T) lines(freq, predict(res, freq), col='red') Another wish is a visulization of the contribution from each of the gaussians to the original peak, eg. the gaussians should be plotted side by side (instead of plotting their sum as done above).

• If Then Statement Condition Being Ignored With Optimisations On

  - by Matma

  I think im going mad but can some show me what im missing, it must be some stupidly simple i just cant see the wood for the trees. BOTH side of this if then else statement are being executed? Ive tried commenting out the true side and moving the condition to a seperate variable with the same result. However if i explicitly set the condition to 1=0 or 1=1 then the if then statement is operating as i would expect. i.e. only executing one side of the equation... The only time ive seen this sort of thing is when the compiler has crashed and is no longer compiling (without visible indication that its not) but ive restarted studio with the same results, ive cleaned the solution, built and rebuilt with no change? please show me the stupid mistake im making using vs2005 if it matters. Dim dset As DataSet = New DataSet If (CboCustomers.SelectedValue IsNot Nothing) AndAlso (CboCustomers.SelectedValue <> "") Then Dim Sql As String = "Select sal.SalesOrderNo As SalesOrder,cus.CustomerName,has.SerialNo, convert(varchar,sal.Dateofpurchase,103) as Date from [dbo].[Customer_Table] as cus " & _ " inner join [dbo].[Hasp_table] as has on has.CustomerID=cus.CustomerTag " & _ " inner join [dbo].[salesorder_table] as sal On sal.Hasp_ID =has.Hasp_ID Where cus.CustomerTag = '" & CboCustomers.SelectedValue.ToString & "'" Dim dap As SqlDataAdapter = New SqlDataAdapter(Sql, FormConnection) dap.Fill(dset, "dbo.Customer_Table") DGCustomer.DataSource = dset.Tables("dbo.Customer_Table") Else Dim erm As String = "wtf" End If EDIT: i have found that this is something to do with the release config settings im using, i guesing its the optimisations bit. does anyone know of any utils/addons for vs that show if a line has been optimised out. delphi, my former language showed blue dots in the left margin to show that it was a compiled line, no dot meaning it wasnt compiled in, is there anything like that for vs? alternatively can someone explain how optimisations would affect this simple if statement causeing it to run both sides? EDIT2: using this thread as possible causes/solutions : http://stackoverflow.com/questions/2135509/bug-only-occurring-when-compile-optimization-enabled. It does the same with release = optimisations on, x86, x64 and AnyCPU Goes away with optimisations off. Im using V2005 on a x64 win7 machine, if that matters. Thanks

• user agent checking for ios6

  - by Akash Saikia

  I am trying to check whether client opening the page is using iOS6 or not. var startIndex = navigator.userAgent.search(/OS/i) + 2; var endIndex = navigator.userAgent.search(/like/i); var iOSVersion = parseInt(navigator.userAgent.substr(startIndex,endIndex - startIndex).trim()); this.iOSVersion = true; if(!isNaN(iOSVersion)){ this.iOSVersion = iOSVersion; } else if(Ext.is.Desktop){ this.iOSVersion = true; } The above code works well for all the versions of browsers. But incase of using it in iOS6, it shows as iOS5. Searched for the same thing, but I didn't find a solution. May be I am still not done with searching for this, doing side by side search and hoping if some one has faced this issue before. Any suggestions or updations?

• How to create a persistent connection using AS3 Sockets for a chat client

  - by Vivek

  I want to create a chat client in flash/flex for a chat server,something like a MUD/MOO client but I'm unable to create a persistent connection . I've been using the AS3 Socket class,but I'm getting disconnected from the server side,soon after the connection is made but the client still shows the 'connected' property as true .The server is asynchronous and was written in python using asyncore/asynchat, it works fine with most open source MOO/MUD clients . I tried connecting my program to a simple synchronous echo server,here both read and write worked fine with no disconnections from either side . So my question is how do I make a persistent connection with the server?

• Any implementations of graph st-ordering or ear-decomposition?

  - by chang

  I'm in the search for an implementation of an ear-decomposition algorithm (http://www.ics.uci.edu/~eppstein/junkyard/euler/ear.html). I examined networkx and didn't find one. Although the algorithm layout is vaguely in my mind, I'd like to see some reference implementation, too. I'm aware of Ulrik Brandes publication on a linear time Eager st-ordering algorithm, which results in an ear decomposition as a side product, if I understand correctly (it even includes pseudocode, which I'm trying to base my implementation on). Side problem: First step could be an st-ordering of a graph. Are there any implementations for st-ordering algorithms you know? Thanks for your input. I'd really like to contribute e.g. to networkx by implementing the ear-decomposition algorithm in python.

• Most performant ASP.NET web controls suite

  - by DotNetter

  Personally I've been working for years with Telerik's RadControls and DevExpress ASP.NET controls. IMHO they both produce quite a lot HTML overhead on the client side thus for that I've never been highly pleased with them. I also know about Infragistics, ComponentOne, ComponentArt, etc. How are these? I'd assume they are not much different than those I mentioned. Which (commercial) controls suite generates the most compact HTML on the client side? Do you have any recommendations?

• flex/actionscript client entity state refresh on JPA update using Pimento EntityManager

  - by Chris

  My Flex application uses a client-side pimento EntityManager which fetches quite a few objects and associations. It does this by forcing eager fetching of particular association ends in the form of fetch plans. I would like to update the client whenever a change has been made to an entity existing in the EntityManager's cache. Is it possible to update the state of the changed entity ONLY, including updating which entities are associated, without resetting the state of these associated entities? I have setup an EntityListener with a JPA post-update method that notifies clients when a persisted entity has been updated. I want this to trigger a refresh for the modified client-side entity, but calling EntityManager.refresh(entity) resets all lazy associations to proxies. Initializing these proxies resets the associated entities, even if they were loaded previously. I'm looking for an efficient way to keep the client's state in synch with the server's state, at least with respect to the entities that have already been retrieved by the initial load.

• How to store or share live data between PHP Requests?

  - by Devyn

  Hi, I want to start a project for facebook and the application will be like real-time multiplayer chess game. The problem I'm having is I have no idea how to store the data when a player moves one piece and update the new position in player2 browser. I'm gonna use PHP, MySQL for server side and jQuery for Client Rendering. The simplest idea is to store the data in XML or MySQL and re-generate the result to player2 browser. But I know that when thousand of players are playing, it will not be an efficient way. Since I don't have time to study new language for this project, I'm gonna have to stick with PHP. I'm not going to use flash either because I want my client side light-weight and flash-free. So is there any way that will solve my problems?

• Multi-platform development from one computer

  - by iama

  I am planning to build a new development computer for both Windows & Linux platforms. On Windows, my development would be primarily in .NET/C#/IIS/MSSQL Server. On Linux—preferably Ubuntu—my development would be in Ruby and Python. I am thinking of buying a laptop with Windows 7 pre-installed with 4GB RAM, Intel Core 2 Duo, and 320 GB HD; running 2 VMs for both Windows and Linux development with the host OS as my work station. Of course, I would be running DBs and web servers on the respective platforms. Is this a typical setup? My only concern is running two VMs side by side. Not sure if this configuration would be optimal. Alternative would be to do my Windows development on the host Windows 7 OS. What are your thoughts?
