• How do I add two alternating UITableViews to an existing UINavigationController view?

  - by Ron Flax

  I'm new to iPhone development and I am writing an iPhone app that needs two different table views, which are selectable using a button bar or tab bar. These table views are both the same size, but only cover about two thirds of the screen from the bottom up. The top portion of the screen remains the same when either of these tables is displayed. I'd also like to animate (flip) these views when the user selects one or the other. The view that these two tables will be displayed on is the detail view of my app where the user has already selected an item from the primary screen's table. I'm using a UINavigationController to manage the primary and detail views and I have this working. I also have the first of these two detail tables working as part of my detail view, but I think it makes more sense to isolate the code for these two tables and not duplicate all of the code for the part of the detail view that doesn't change. I don't really care how these two table views are created (either in code or via IB). I've tried several things and I can't seem to figure it out. Any help or ideas (with sample code) would be greatly appreciated!

• CSS Background image in Redmine template arbitrarily not loading

  - by Pekka

  I`m in the process of building a template for Redmine (a project management system based on Ruby on Rails.) Ruby is running on a virtual server from a Bitnami.org installation package. The OS is Windows. The template essentially consists of a styles.css file. In that file, I have the following line: #header { padding: 0px; padding-top: 48px; background-color: #62DFFF; background-image: url(../images/bkg.jpg) background-position: center bottom; background-repeat: repeat-x; height:150px; } It's a header element with a background image. The problem: This background image arbitrarily appears and disappears when reloading. Say you reload ten times in twenty seconds; the image will appear in two instances, and be missing in the 18 others. I would have put this down to server problems, but the weird thing is that when it's missing, the request for the image doesn't appear in Firebug's net tab at all. Even if it were cached, the request should be there. Raw screenshots of the identical page on two reloads: I am 100% sure the CSS file does not change in between. I have examined both instances with Firebug and the CSS is identical. It happens in both Firefox and Chrome so it must be something basic I'm overlooking. What could be causing a browser not to load a resource at all? I have zero idea about Ruby nor Rails - getting Redmine running and customized is all I have ever had to do with this platform - so I don't really know where to look. Apache's, Mongrel's and Redmine's error logs look fine, though.

• Exporting WPF DataGrid to a text file in a nice looking format. Text file must be easy to read.

  - by Andrew

  Hi, Is there a simple way to export a WPF DataGrid to a text file and a .csv file? I've done some searching and can't see that there is a simple DataGrid method to do so. I have got something working (barely) by making use of the ItemsSource of the DataGrid. In my case, this is an array of structs. I do something with StreamWriters and StringBuilders (details available) and basically have: StringBuilder destination = new StringBuilder(); destination.Append(row.CreationDate); destination.Append(seperator); // seperator is '\t' or ',' for csv file destination.Append(row.ProcId); destination.Append(seperator); destination.Append(row.PartNumber); destination.Append(seperator); I do this for each struct in the array (in a loop). This works fine. The problem is that it's not easy to read the text file. The data can be of different lengths within the same column. I'd like to see something like: 2007-03-03 234238423823 823829923 2007-03-03 66 99 And of course, I get something like: 2007-03-03 234238423823 823829923 2007-03-03 66 99 It's not surprising giving that I'm using Tab delimiters, but I hope to do better. It certainly is easy to read in the DataGrid! I could of course have some logic to pad short values with spaces, but that seems quite messy. I thought there might be a better way. I also have a feeling that this is a common problem and one that has probably been solved before (hopefully within the .NET classes themselves). Thanks.

• c++ - strange problem with polymorphism - cellular automaton

  - by Green

  Hello, I am making "game of life" implementation that, when cell has: two live neighbours I make object of class CCellB two live neighbours I make object of class CCellA when has 3 or <2 I make object of class CCellX (dead) Class CCell is base of CCellA, CCellB, CCellX My problem is: That works fine, until I change new CCell(); to new CCellB();: CCell ***temp = allocateArray(); for(int i = 0; i < n; i++) { for(int j = 0; j < m; j++) { c = arr[i][j]->countAliveNeighbor(); if(c == 3) { temp[i][j] = new CCellA(); temp[i][j]->alive = 1; }else if(c == 2) { temp[i][j] = new CCell(); // HERE, WHEN I CHANGE IT TO CCELLB IT DON'T WORKS temp[i][j]->alive = tab[i][j]->alive; }else if((c >= 4)||(c < 2)) { temp[i][j] = new CCellX(); } } } Then it seems don't work properly... Seems like neighbours are not count properly, Cell with 4,5 neighbours still alive alive var is member of base class - CCell, all is public, please help!

• DRYing up Rails Views with Nested Resources

  - by viatropos

  What is your solution to the problem if you have a model that is both not-nested and nested, such as products: a "Product" can belong_to say an "Event", and a Product can also just be independent. This means I can have routes like this: map.resources :products # /products map.resources :events do |event| event.resources :products # /events/1/products end How do you handle that in your views properly? Note: this is for an admin panel. I want to be able to have a "Create Event" page, with a side panel for creating tickets (Product), forms, and checking who's rsvp'd. So you'd click on the "Event Tickets" side panel button, and it'd take you to /events/my-new-event/tickets. But there's also a root "Products" tab for the admin panel, which could list tickets and other random products. The 'tickets' and 'products' views look 90% the same, but the tickets will have some info about the event it belongs to. It seems like I'd have to have views like this: products/index.haml products/show.haml events/products/index.haml events/products/show.haml But that doesn't seem DRY. Or I could have conditionals checking to see if the product had an Event (@product.event.nil?), but then the views would be hard to understand. How do you deal with these situations? Thanks so much.

• Core Data: Overkill for simple, static UITableView-based iPhone App?

  - by David Foster

  Hello! I have a rather simple iPhone app consisting of numerous views containing a single, grouped table view. These views are held together in navigation controllers which are grouped in a tab bar. Simple stuff. My table views do little more than list text (like "Dog", "Cat" and "Weasel") and this data is being served from a collection of plists. It's perhaps worth mentioning too that these tables are 'static' in the sense that their data is pre-determined and will only ever be amended—and if so, very rarely indeed—by the developer (in this case, moi). This rudimentary approach has reached its limits though, and I think I'm going to need something a bit more relational. I have worked a tad with Core Data in the past, but only with apps whose data is determined by user input. I have four closely related questions: Is Core Data overkill for an app consisting mainly of a selection of simple table views? Do you recommend using Core Data to manage data which is predetermine and extremely unlikely to ever change? Can one lock Core Data down so that its data can't change, thereby relinquishing my responsibility as the developer to handle the editing and saving of the managed object context? How do I go about giving Core Data my predetermined data, and in a format I know that it can work with? Thanks a bunch guys.

• Problem when get pageContent of URL in java ?

  Hi all ! i have a code for get pagecontent from a URL here is code ! import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; import java.net.URL; import java.net.URLConnection; public class GetPageFromURLAction extends Thread { public String stringPageContent; public String targerURL; public String getPageContent(String targetURL) throws IOException { String returnString=""; URL urlString = new URL(targetURL); URLConnection openConnection = urlString.openConnection(); String temp; BufferedReader in = new BufferedReader(new InputStreamReader(openConnection.getInputStream())); while ((temp = in.readLine()) != null) { returnString += temp + "\n"; } in.close(); // String nohtml = sb.toString().replaceAll("\\<.*?>",""); return returnString; } public String getStringPageContent() { return stringPageContent; } public void setStringPageContent(String stringPageContent) { this.stringPageContent = stringPageContent; } public String getTargerURL() { return targerURL; } public void setTargerURL(String targerURL) { this.targerURL = targerURL; } @Override public void run() { try { this.stringPageContent=this.getPageContent(targerURL); } catch (IOException e) { e.printStackTrace(); } } } The problem is : 1 Some time i receive a error lik 405 ,or 403 HTTP error ... and result string is null . To repair i check permission to connect URL but it usualy return null URLConnection openConnection = urlString.openConnection(); openConnection.getPermission( ) is mean that i don't have permission to acess link ? To get resultString without HTML Tag ? i do like that String nohtml = sb.toString().replaceAll("\<.*?",""); Para sb is Stringbulder , but it can't remove all HTML Tab in string return ? I use thread here because i must get page alot of url , so how can i cread a multi thread to impro speed of program ! Thanks

• Changing the direction of a Combo box dropdown in SWT

  - by Kris

  Hi, I'm building an Eclipse plugin in SWT, and I have the following problem: one of my fields is a combo box, and in some cases it may have fairly long items as selection options. My plugin runs on the right side of the screen, so when you go to use the combo-box, the right side of the combo box is cut off. So, my question is: is there any way to change the dropdown's alignment relative to the combo control? It seems to be permanently left-aligned... and I'm pretty sure you can change the direction in Swing (though the only place I've seen it done is in the Substance UI demo. The Combo Box tab has boxes with North, South East, and West flyout directions... for my application, I need something like the West flyout) Note: Setting actual text limits is a last-case-scenario option; it would be quite a bit of guesswork to set the text limit dynamically (since the widget's view can be resized). Here's a picture (sorry, I can only have one link and no images :( ... I need some more rep :p) Left side of the line: Proper width - the view is the wide enough for the combo dropdown to display all the text; you can see the scrollbars on the right side. Right side of the line: Too small - Here, the view has been resized, and the combo dropdown scrollbar (as well as some of the text) is cut off by the right side of the screen. I always have more screen space available to the left (since this is always on the right hand side of the screen), but the combo dropdown always appears to the lower right. Hopefully this is clear enough.

• IDE framework for a dynamic language?

  - by Kevin Reid

  Let's say I have a super-wonderful new programming language, and I want there to be an IDE for it. What IDE platform/framework could I use to get this done efficiently? I mean things like: Collection of files in a project, searching them, tabbed/split editors etc. — the basics. Syntax highlighting and auto-indent/reformatting. Providing the user interface for code completion — hit tab, get a list (I'll have to implement the necessary partial evaluation myself (it's a dynamic language)). This is the feature I'm most wishing for. Built-in parser framework which is good at recovering from the sort of syntax errors occurring in code that is in the middle of being edited would be helpful. In-editor annotation of syntax/runtime error locations fed back from the language runtime. REPL (interactive evaluator) interaction with the same completion as in the editor. This system should be Linux/Mac/Windows cross-platform (in that priority order). Being implemented in Java (or rather, accepting language plugins written in Java) is possibly useful, but anything else is worth a try too.

• SQL Server 2008 - db mail issue

  - by Chris

  Hello. I have two instances of SQL Server 2008. One was upgraded from SQL Server 2000 and one was a clean, new install. SQL Mail operates perfectly on both instances. DB Mail operates perfectly on the newly installed instance. On the upgraded instance, DB Mail does not send any mail. Of course, I am not positive that the fact this instance is upgraded has anything to do with the issue, but it might. The configuration of my db mail profile and account looks identical to my functioning instance. In the configuration of the 'alerts' tab in the SQL Agent properties i have tried selecting both DB Mail and SQL Mail to no avail. Both instances use the same SMTP server with the same authentication (domain with db engine account). All messages sent via sp_send_db mail and those sent via the 'test email' option are visible in the sysmail_allitems queue and remain there as 'unsent'. The send_status eventually changes to 'failed'. The only messages in the sysmail_event_log are 'mail queue stopped by login domain\myuser', 'mail queue started by login domain/myuser' and 'activiation successful.'. selecting from the externalmailqueue has the same number of rows as sysmail_allitems. i have tried bouncing the agent, the entire instance and moving the other functioning instance to the other node in the cluster. any thoughts? thx.

• Ajax UpdatePanels SetFocus issue

  - by George

  I set the AutoPostback property of a textbox to True so I can process the TextChanged event on the server and, based on what they typed in the textbox, appropriately display a message in an update panel. The problem is, when the partial screen refresh is performed, no control on the screen has focus. 99% of the time, when the text in the textbox is changed, it is because the user has tabbed forward, and so, to limit the disruption in the lost of focus, I perform a "Focus" call on teh next control in the tab sequence. For the most part, this works OK, but of course, is disputive if the user is tabbing in the reverse order or has used the mouse to set the focus to another control. In these situations, the focus would be set to the next control even though the user was trying to set focus elsewhere. OK, that sucks. Now what I consider the bigger problem with calling the focus method on the server: In IE, it works OK, but in Mozilla Firefox and Chrome, setting the focus causes a repositioning of the scroll bar, even though none is necessary because the control is already in view. I realize that I could switch to doing AJAX web service calls, but these darn Updae Panels are so convenient if used in moderation. is there anyway to use updatepanels and not have these focus/scroll issues?

• Virus on site but can't find where

  - by Rob

  WARNING! THIS IS ABOUT A VIRUS ON MY SITE. IT APPEARS IT HAS BEEN THERE FOR SOMETIME AND I'VE HAD NO PROBLEMS. BUT PLEASE BE CAREFUL. READ EVERYTHING I SAY AND SEE IF YOU CAN HELP ME WITHOUT VISITING THE LINK. AVG PICKS UP ON IT AND BLOCKS IT, MCAFEE DOES NOT. Sorry about the warning, obviously i'm not here to get anyone infected or anything like that. Basically I run the website sortitoutsi dot net. Ages ago I got a virus on my computer, they got hold of my FTP passwords and added some lines of javascript to the top of my site. I removed them and believe it was fixed. However i'm using the "Web Developer" extension for Firefox and chose to view all javascript on my page and find there are various links to horrible urls such as: gittigidiyor-com.excite.co.jp.webmasterworld-com.eastmusicdirect.ru:8080/aboutus.org/aboutus.org/google.com/skycn.com/torrents.ru.php and gittigidiyor-com.excite.co.jp.webmasterworld-com.eastmusicdirect.ru:8080/index.php?jl= These terms do not appear anywhere. In the source code, in any of the javascript or the css. I also can't see that there are any rogue images that I don't recognise either. So i've no idea where this javascript is coming from. Can anyone suggest how I can find references to these links and remove them? I can see them both in the Web Developer firefox extension and in the net tab using Firebug. Any help would be greatly appreciated

• Can Delphi dragging be "promoted" to docking?

  - by mghie

  I have a TPageControl whose pages are all various forms that are attached using ManualDock(). The user should be able to rearrange the tabs by dragging them, which works already. It should however also be possible to undock the docked forms. For now I have the following code: procedure TMainForm.PageControlMouseDown(Sender: TObject; Button: TMouseButton; Shift: TShiftState; X, Y: Integer); begin if (Button = mbLeft) and (Shift * [ssShift, ssCtrl] = []) and PageControl.DockSite then begin PageControl.BeginDrag(False, 32); end; end; If either the Shift or the Ctrl key are held down, then a docking operation will be started, otherwise the tabs can be rearranged by dragging them. Using the keys as modifiers is awkward though. Is there any way to cancel the active drag operation when the mouse cursor is outside of the tab area of the page control, and start docking the child form? This is with Delphi 2009.

• Characters in usernames that cause trouble

  - by acidzombie24

  I am testing out security and reliability issues on my site. I have made \n and \r illegal. I created a user with null in the name which caused my PM system to not message the user. However \b worked and \t didnt allow copy/paste to work correctly. The browser (firefox which i am testing with) copied the tab as a single space causing the name not to be the same thus not recognizing the username. Since i cant copy paste easily i'll probably disallow it. \f works as well although i do see a symbol in the title but nowhere else because of the \f. What else should i try? It appears 0-31 127-159 (i dont understand this range) are illegal. What characters in legal range might i want to disallow? I heard there was a 0 width character space. That may be something i want to disallow? What else is there?

• How can I sign a Windows Mobile application for internal use?

  - by AR

  I'm developing a Windows Mobile application for internal company use, using the Windows Mobile 6 Professional SDK. Same old story: I've developed and tested on the emulator and all is well, but as soon as I deploy to advice I get an UnauthorizedAccessException when writing files or creating directories. I'm aware that an application installed to a device needs to be signed but I'm running into roadblocks at every turn: Using the project properties 'Devices' window I select 'Sign the project output with this certificate, and choose one of the sample certificates from the SDK. This results in a build error: "The signer's certificate is not valid for signing" when running SignTool. If I try to run SignTool.exe from the commandline, I get an error telling me to run SignTool.exe from a location in the system's PATH. I can't use the 'Signing' tab in the Project Properties to create a test certificate - this is greyed out (presumably for WinMobile projects?). If at all possible, I would like to avoid having to go through Versign or the like to get a Mobile2Market certificate. If I have to go this route for a final version that's fine, but I need to at least be able to test the app on real devices. Any advice would be most welcome!

• How to detect if a file is PDF or TIFF ?

  - by eviljack

  Please bear with me as I've been thrown into the middle of this project without knowing all the background. If you've got WTF questions, trust me, I have them too. Here is the scenario: I've got a bunch of files residing on an IIS server. They have no file extension on them. Just naked files with names like "asda-2342-sd3rs-asd24-ut57" and so on. Nothing intuitive. The problem is I need to serve up files on an ASP.NET (2.0) page and display the tiff files as tiff and the PDF files as PDF. Unfortunately I don't know which is which and I need to be able to display them appropriately in their respective formats. For example, lets say that there are 2 files I need to display, one is tiff and one is PDF. The page should show up with a tiff image, and perhaps a link that would open up the PDF in a new tab/window. The problem: As these files are all extension-less I had to force IIS to just serve everything up as TIFF. But if I do this, the PDF files won't display. I could change IIS to force the MIME type to be PDF for unknown file extensions but I'd have the reverse problem. http://support.microsoft.com/kb/326965 Is this problem easier than I think or is it as nasty as I am expecting?

• Can Content script set value of a text box within HTML frame? using Google Chrome extensions..

  - by devdreamers

  Hi all, I was working on a very simple extension, where on clicking extension icon, a webpage is opened in a new tab, the webpage has HTML frames, within which lies a textbox. I want to set a value for the same. The webpage which opens has: <HTML> <FRAMESET rows="15%, *" border="0"> <FRAME src="./files/abc.htm" id="abc_frame" name="abc_frame" onload="abcLoad()" scrolling="NO"> </FRAMESET> </HTML> and abc.htm has: <div align="center" valign="bottom" style="font-size: 1em;"> <form onSubmit="javascript:navigate(this);return false;"> <label for="loc">Loc</label>: <input type="text" size="50" id="loc" value="http://google.com"/> <input name="go" type="submit" value="Go" id="loc_go" onclick='navigate(this); return false;'/> </form> </div> how can I replace current textbox value with, say http://yahoo.com ?

• Vim: yank and replace -- the same yanked input -- multiple times, and two other questions

  - by Hassan Syed

  Now that I am using vim for everything I type, rather then just for configuring servers, I wan't to sort out the following trivialities. I tried to formulate Google search queries but the results didn't address my questions :D. Question one: How do I yank and replace multiple times ? Once I have something in the yank history (if that is what its called) and then highlight and use the 'p' char in command mode the replaced text is put at the front of the yank history; therefore subsequent replace operations do not use the the text I intended. I imagine this to be a usefull feature under certain circumstances but I do not have a need for it in my workflow. Question two: How do I type text without causing the line to ripple forward ? I use hard-tab stops to allign my code in a certain way -- e.g., FunctionNameX ( lala * land ); FunctionNameProto ( ); When I figure out what needs to go into the second function, how do I insert it without move the text up ? Question three Is there a way of having a uniform yank history across gvim instances on the same machine ? I have 1 monitors. Just wondering, atm I am using highlight + mouse middle click.

• How to tell what account my webservice is running under in Visual Studio 2005

  - by John Galt

  I'm going a little nuts trying to understand the doc on impersonation and delegation and the question has come up what account my webservice is running under. I am logged as myDomainName\johna on my development workstation called JOHNXP. From Vstudio2005 I start my webservice via Debug and the wsdl page comes up in my browser. From Task Manager, I see the following while sitting at a breakpoint in my .asmx code: aspnet_wp.exe pid=1316 UserName=ASPNET devenv.exe pid=3304 UserName=johna The IIS Directory Security tab for the Virtual Directory that hosts my ws.asmx code has "Enable Anonymous access" UNCHECKED and has "Integrated Windows Authentication" CHECKED. So when the MSDN people state "you must configure the user account under which the server process runs", what would they be refering to in the case of my little webservice described above? I am quoting from: http://msdn.microsoft.com/en-us/library/aa302400.aspx Ultimately, I want this webservice of mine to impersonate whatever authenticated domain user browses through to an invoke of my webservice. My webservice in turn consumes another ASMX webservice on a different server (but same domain). I need this remote webservice to use the impersonated domain user credentials (not those of my webservice on JOHNXP). So its getting a little snarly for me to understand this and I see I am unclear about the account my web service uses. I think it is ASPNET in IIS 5.1 on WinXP but not sure.

• jquery image fading with tabs

  - by StealthRT

  Hey all, i am trying my best to figure out how to go about doing this: I have 2 tabs. When the page loads tab1 is selected automatically. This shows the tab as 1.0 transparency while tab2 stays at 0.7. Once the user clicks on tab2, tab1 goes to 0.7 transparency and tab2 goes to 1.0. However, i can not seem to get it to do that! Here is my code: <script type="text/javascript"> function checkTab(theTab) { $('#tab1').fadeTo(250, 0.70); $('#tab2').fadeTo(250, 0.70); if ($("#tabActive").val() == theTab) { $(theTab).fadeTo(250, 1); } } $(document).ready(function() { $('#tab1').hover(function() {$(this).fadeTo(250, 1)}, function() {checkTab('#tab1')}); $('#tab2').hover(function() {$(this).fadeTo(250, 1)}, function() {checkTab('#tab2')}); $('#tab2').fadeTo(250, 0.70); $('#tabActive').val('tab1'); }); </script> <li class="stats"><img src="images/Stats.png" name="nav1" width="70" height="52" id="tab1" onclick="$('#tabActive').val('tab1');" /></li> <li class="cal"><img src="images/cal.png" name="nav1" width="70" height="52" id="tab2" onclick="$('#tabActive').val('tab2');" /></li> <input name="tabActive" id="tabActive" type="text" /> Any help would be great! :) David

• How do I use HTML5's localStorage in a Google Chrome extension?

  - by davidkennedy85

  I am trying to develop an extension that will work with Awesome New Tab Page. I've followed the author's advice to the letter, but it doesn't seem like any of the script I add to my background page is being executed at all. Here's my background page: <script> var info = { poke: 1, width: 1, height: 1, path: "widget.html" } chrome.extension.onRequestExternal.addListener(function(request, sender, sendResponse) { if (request === "mgmiemnjjchgkmgbeljfocdjjnpjnmcg-poke") { chrome.extension.sendRequest( sender.id, { head: "mgmiemnjjchgkmgbeljfocdjjnpjnmcg-pokeback", body: info, } ); } }); function initSelectedTab() { localStorage.setItem("selectedTab", "Something"); } initSelectedTab(); </script> Here is manifest.json: { "update_url": "http://clients2.google.com/service/update2/crx", "background_page": "background.html", "name": "Test Widget", "description": "Test widget for mgmiemnjjchgkmgbeljfocdjjnpjnmcg.", "icons": { "128": "icon.png" }, "version": "0.0.1" } Here is the relevant part of widget.html: <script> var selectedTab = localStorage.getItem("selectedTab"); document.write(selectedTab); </script> Every time, the browser just displays null. The local storage isn't being set at all, which makes me think the background page is completely disconnected. Do I have something wired up incorrectly?

• Displaying Flex Object References

  - by Pie21

  I have a bit of a memory leak issue in my Flex application, and the short version of my question is: is there any way (in AcitonScript 3) to find all live references to a given object? What I have is a number of views with presentation models behind each of them (using Swiz). The views of interest are children of a TabNavigator, so when I close the tab, the view is removed from the stage. When the view is removed from the stage, Swiz sets the model reference in the view to null, as it should. I also removeAllChildren() from the view. However when profiling the application, when I do this and run a GC, neither the view nor the presentation model are freed (though both set their references to each other to null). One model object used by the view (not a presenter, though) IS freed, so it's not completely broken. I've only just started profiling today (firmly believing in not optimising too early), so I imagine there's some kind of reference floating around somewhere, but I can't see where, and what would be super helpful would be the ability to debug and see a list of objects that reference the target object. Is this at all possible, and if not natively, is there some light-weight way to code this into future apps for debugging purposes? Cheers.
