  • How to set background color of tableView

    - by Praveen
    Hi Folks, I have tried all the way but could not succeed to set backgroundColor of TableView. setting tableView.backgroundColor and/or cell.backgroundColor to clearColor didn't work when the parent view controller was UIViewContoller. My nib file structure is FileOwner View UITableView (Note: i set the TableView to groupedTable section) First attempt, I created the UIView in the code viewDidLoad UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 160, 300)] autorelease; [view setBackgroundColor:UIColor blueColor]; // color it just to see if it is created at the right place [self.tableView sendSubViewToBack:view]; It works but it hides the content of cell. I am able to see the content of header but not cell content. (But when i change the co-ordinate of view(0,150,160,300) then i am able to see the cell's content but then it loose the backgroundColor of tableview. Second attempt, I created the imageView View ImageView UITableView and set the self.tableView.backgroundColor = [UIColor clearColor]; but did not work. I googled but did not the peaceful answer.

  • Getting Google repositories to work with apt-get on Ubuntu Hardy

    - by Justin
    I've installed Google Chrome on Hardy via the .deb file and would like to configure apt-get for automatic updates. [I have another machine running Ubuntu Karmic where this works fine; apt-get knows the package as 'google-chrome'; I'm now using a Dell Mini 10 with Ubuntu 8.04 LTS installed] As part of the .deb install, two entries have been added to the third- party software sources tab: http://dl.google.com/linux/deb stable main http://dl.google.com/linux/deb stable non-free main However if I check for updates with either of these clicked, I get the following error: Failed to fetch http://dl.google.com/linux/deb/dists/stable/Release Unable to find expected entry main/binary-lpia/Packages in Meta-index file (malformed Release file?) There is a thread here which indicates others have had the same problem: http://www.google.co.uk/support/forum/p/Chrome/thread?tid=097d103f87b49abe&hl=en This references a further thread: http://code.google.com/p/chromium/issues/detail?id=38608 which suggests the problem has been fixed. Despite this I remain unable to get it to work, and none of the suggested workarounds seem to work either. Ideas ? Thanks.

  • Windows Azure Worldwide availability

    - by Insomniac
    Hi, I've been reviewing Windows Azure platform for some time, and can't find answer to one very important question. If I deploy my application within a cloud, how it will be reached from different places worldwide? For example if I have a web application with a database and want it to be accessible to users in UK, US, China and etc. Can I be sure that any user in the world will get almost the same request processing time? I think of it this way. 1. User sends request (navigates in browser to my web site) 2. This request gets in a cloud in a nearest location (closest to user MS Data Center?) 3. It is processed by an instance of my web application (in nearest location, with request to my centralized DB which can be far away but SQL request goes via MS internal network, which I believe should be very fast). 4. Response sent to user. Please let me know if I'm wrong. Thanks.

  • How difficult is it to write our own Robots API, similar to G Wave Robots API ? Please read the deta

    - by user169650
    Consider the following entities : a) My own Wave-server b) My own Robots API c) Tomcat d) Google wave server/any other wave server Let us consider that a and d interact with one another via Google wave federation protocol. Now, I want to write my own Robots API in Java (similar to that of G Wave Robots API) using which I want to create Robots; which I want to host in entity c), which may in-turn connect to a) for listening to events and responding with operations. Let us consider that a) is already in place, i.e. implemented. Let us also consider that the Robot running on tomcat and entity a) are co-located, so that we do not need to use JSON-RPC for receiving events/sending operations; instead we can use Java interfaces. Now, my questions are : 1.How much of an effort is it to write my own Robots API to run on a tomcat container ? 2.What are the salient points to be taken care of ? Am I missing some important point here ? 3.How can I reuse some of the classes/packages/interfaces (e.g. com.google.wave.api.AbstractRobot, com.google.wave.api.event) with little/no changes at all ?

  • Help Installing phpMyAdmin on Linux Server

    - by Joe Majewski
    I constantly get this error when attempting to view index.php in the phpMyAdmin folder I have setup: Cannot start session without errors, please check errors given in your PHP and/or webserver log file and configure your PHP installation properly. I am using subversion with three co-workers and I am trying to install this on my repository, which is at /svni3/myusername/intranet/ on our linux development server. I do have shell access so I would be able to install it somewhere else if that may be causing the problem. My config.inc.php file looks like this (only the things I changed): $cfg['blowfish_secret'] = 'blah'; $cfg['Servers'][$i]['auth_type'] = 'cookie'; //$cfg['Servers'][$i]['user'] = 'username'; //$cfg['Servers'][$i]['password'] = 'password'; $cfg['Servers'][$i]['host'] = 'localhost'; Other helpful information??? When I ping localhost it works. When I run the command "ls -l /var/lib/php": drwxrwx--- 2 root apache 4096 2009-04-17 02:31 session If there's anything else that may be helpful let me know; this has been plaguing me for a few hours now.

  • C++ and its type system: How to deal with data with multiple types?

    - by sub
    "Introduction" I'm relatively new to C++. I went through all the basic stuff and managed to build 2-3 simple interpreters for my programming languages. The first thing that gave and still gives me a headache: Implementing the type system of my language in C++ Think of that: Ruby, Python, PHP and Co. have a lot of built-in types which obviously are implemented in C. So what I first tried was to make it possible to give a value in my language three possible types: Int, String and Nil. I came up with this: enum ValueType { Int, String, Nil }; class Value { public: ValueType type; int intVal; string stringVal; }; Yeah, wow, I know. It was extremely slow to pass this class around as the string allocator had to be called all the time. Next time I've tried something similar to this: enum ValueType { Int, String, Nil }; extern string stringTable[255]; class Value { public: ValueType type; int index; }; I would store all strings in stringTable and write their position to index. If the type of Value was Int, I just stored the integer in index, it wouldn't make sense at all using an int index to access another int, or? Anyways, the above gave me a headache too. After some time, accessing the string from the table here, referencing it there and copying it over there grew over my head - I lost control. I had to put the interpreter draft down. Now: Okay, so C and C++ are statically typed. How do the main implementations of the languages mentioned above handle the different types in their programs (fixnums, bignums, nums, strings, arrays, resources,...)? What should I do to get maximum speed with many different available types? How do the solutions compare to my simplified versions above?

  • Is the 'var' keyword bad? Or am I just old school?

    - by WaggingSiberian
    Recently I overheard junior developer ask "why do you use 'var' so much?". The mid-level developer responded "I use VAR all the time. I love it! I don't have to figure out the type." I didn't have the time or energy to get into a religious war and hey, I'm still the new guy here :-) I understand var has its place. LINQ comes to mind. But I have also always been told the use of var represents lazy programming and I should just use the correct type to begin with. If it's an int, define it as an int, not a var. When reviewing code, seeing the type makes it easier to follow. My opinion is, it's just lazy but there are exceptions. Var also reminds me of the VB/VBA variant type. It also had its place. I recall (from many years ago) its usage being less-than-desirable type and it was rather resource hungry. Am I just being stuck in my ways? Should we start using var all the time as my co-worker does?

  • How to get the value of an XML element using Linq even when empty.

    - by Yeodave
    Please excuse my stupidity, I tend to find the traversing XML overly complicated. I am using ASP.NET in VB. I have an XML document which contains all the details of staff in my company... <staff> <staffName>Test Staff</staffName> <staffTitle>Slave</staffTitle> <staffDepartmentName>Finance</staffDepartmentName> <staffOffice>London</staffOffice> <staffEmail>t.staff@battens.co.uk</staffEmail> <staffPhone>0207 123 456</staffPhone> <staffNotes>Working hours Mon to Thurs 9.15 - 5.15</staffNotes> <staffBio></staffBio> </staff> As you can see, some nodes do not always contain data for ever member of staff; only Directors have biographies. I access the values like this... For Each staff In ( _ From matches In myXMLFile.Descendants("staff").Descendants("staffName") _ Where matches.Nodes(0).ToString.ToLower.Contains(LCase(search)) _ Order By matches.Value _ Select matches) staffName = staff.Descendants("staffName").Nodes(0).ToString) staffTitle = staff.Descendants("staffTitle").Nodes(0).ToString) staffOffice = staff.Descendants("staffOffice").Nodes(0).ToString) staffEmail = staff.Descendants("staffEmail").Nodes(0).ToString) staffPhone = staff.Descendants("staffPhone").Nodes(0).ToString) staffNotes = staff.Descendants("staffNotes").Nodes(0).ToString) staffBio = staff.Descendants("staffBio").Nodes(0).ToString) ' Do something with that data... Next Once it gets to staffBio I get an error saying "Object reference not set to an instance of an object." obviously because that node does not exist. My question is how can I assign the value to a variable even when it is empty without having to do a conditional check before each assignment?

  • Shared Git repo syncing to svn causing git svn rebase to pollute repo with a log of no-op merge prob

    - by John K
    This wasn't so bad at the beginning, but now I have hundreds of no-op merge problems (solved by git rebase --skip). I have setup a shared git repo for my group because it is easier to deal with. But the company uses SVN so I have to keep SVN in sync with GIT. Worked like a dream at first, but after weeks of doing this GIT is giving me a lot of the following errors. Applying: * making all config actions work Using index info to reconstruct a base tree... Falling back to patching base and 3-way merge... Auto-merging app/controllers/vulnerabilities_controller.rb CONFLICT (content): Merge conflict in app/controllers/vulnerabilities_controller.rb Auto-merging public/javascripts/network_analysis_vulnerability_config.js CONFLICT (content): Merge conflict in public/javascripts/network_analysis_vulnerability_config.js Failed to merge in the changes. Patch failed at 0046 * making all config actions work My workflow: git co master git pull origin git svn rebase ... deal with no-op merge problems ... git svn dcommit git pull origin git push origin The problem is that what is in SVN is the correct so I use git rebase --skip, but I have to do that hundreds of times before I can dcommit. How do I clear these merge problems permanently?

  • Get Multiple Values From Database ASP.NET/C#

    - by user1043177
    I am trying to get/return multiple values from an SQL-Server database using and display them on an ASP.NET page. I am using a stored procedure to perform the SELECT command on the Database side.

  • Read all sub directories within a certain folder to display a random image.

    I have this code i have been using....but i need a conditional where it will read all the sub directories of /bg to select an image as opposed to a specific folder if they were on a subpage. Heres my code so far which works perfectly for all subpages to display specific images: //This would tell us its on the homepage if it helps: $this->level() == 0 //This is the code so far $path = '/home/sites/mydomain.co.uk/public_html/public/images/bg/'.$this->slug; $homepagefile = URL_PUBLIC.'public/images/bg/'.$this->slug.'/main.jpg'; $bgimagearray = array(); $iterator = new DirectoryIterator($path); foreach ($iterator as $fileinfo) { if ($fileinfo->isFile() && !preg_match('\.jpg$/', $fileinfo->getFilename())) { $bgimagearray[] = "'" . $fileinfo->getFilename() .

  • How can I work out if a date is on or before today?

    - by Yvonne
    My web application consists of library type system where books have due dates. I have the current date displayed on my page, simply by using this: date_default_timezone_set('Europe/London'); $date = date; print $date("d/m/Y"); I have set 'date' as a variable because I'm not sure if it makes a difference when I use it in the IF statement you're about see, on my library books page. On this page, I am simply outputting the due dates of the books, many have dates which have not yet reached todays date, and others which have dates greater than todays date. Basically, all I want is the due date to appear bold (or strong), if it has passed todays date (the system displayed date). This is what I have and thought would work: <? if ($duedate < $date) { echo '<td><strong>'; } else { echo '<td>'; } ?> <?php echo $date('d/m/Y', $timestamp);?></strong></td> I have declared $timestamp as a var which converts the date of default MySQL format to a UK version. Can anyone help me out? I thought this would've been very straight forward!

  • Where to start with the development of first database driven Web App (long question)?

    - by Ryan
    Hi all, I've decided to develop a database driven web app, but I'm not sure where to start. The end goal of the project is three-fold: 1) to learn new technologies and practices, 2) deliver an unsolicited demo to management that would show how information that the company stores as office documents spread across a cumbersome network folder structure can be consolidated and made easier to access and maintain and 3) show my co-workers how Test Drive Development and prototyping via class diagrams can be very useful and reduces future maintenance headaches. I think this ends up being a basic CMS to which I have generated a set of features, see below. 1) Create a database to store the site structure (organized as a tree with a 'project group'-project structure). 2) Pull the site structure from the database and display as a tree using basic front end technologies. 3) Add administrator privileges/tools for modifying the site structure. 4) Auto create required sub pages* when an admin adds a new project. 4.1) There will be several sub pages under each project and the content for each sub page is different. 5) add user privileges for assigning read and write privileges to sub pages. What I would like to do is use Test Driven Development and class diagramming as part of my process for developing this project. My problem; I'm not sure where to start. I have read on Unit Testing and UML, but never used them in practice. Also, having never worked with databases before, how to I incorporate these items into the models and test units? Thank you all in advance for your expertise.

  • Question about how AppFabric's cache feature can be used.

    - by Kevin Buchan
    Question about how AppFabric's cache feature can be used. I apologize for asking a question that I should be able to answer from the documentation, but I have read and read and searched and cannot answer this question, which leads me to believe that I have a fundamentally flawed understanding of what AppFabric's caching capabilities are intended for. I work for a geographically disperse company. We have a particular application that was originally written as a client/server application. It’s so massive and business critical that we want to baby step converting it to a better architected solution. One of the ideas we had was to convert the app to read its data using WCF calls to a co-located web server that would cache communication with the database in the United States. The nature of the application is such that everyone will tend to be viewing the same 2000 records or so with only occasional updates and those updates will be made by a limited set of users. I was hoping that AppFabric’s cache mechanism would allow me to set up one global cache and when a user in Asia, for example, requested data that was not in the cache or was stale that the web server would read from the database in the USA, provide the data to the user, then update the cache which would propagate that data to the other web servers so that they would know not to go back to the database themselves. Can AppFabric work this way or should I just have the servers retrieve their own data from the database?

  • JavaScript library not working in IE, can't see error information.

    - by Wolfy87
    Hi there. I have been writing a JavaScript library for a few weeks now and it works brilliantly in Firefox, Chrome and Safari. I had not tested it in IE until recently. I do not own a Windows box so after testing it on my friends and realising it wasnt working I started going over my code for things that could be causing it to break. So far I have found nothing. I could not find any descriptions of the errors in the browser while I was there either. So I wondered if anyone could run my test script in an IE browser (6, 7 or 8) and let me know any information they can find as to why it crashed. Please ignore any information saying it works in IE6, I put that up there after testing it through http://ipinfo.info/netrenderer/ I just assumed it was working because I could set transparency and size via my script and see it run in this tool. Here is the link to my GitHub repository: https://github.com/Wolfy87/Spark If you download it and run spark.html it will attempt to run all of my functions from the library. So if anyone could be kind enough to run it in IE and either let me know what errors they are getting and possibly how to fix them then I will be extreamly grateful. Thank you in advance. EDIT: Here is it's website http://sparkjs.co.uk/

Im going to try and do a regex on this this is where I need to integrate the regex somewhere in this code. I need to take the lat and long from the Link element and seperate it into two variables I can use (the results are part of a foreach loop that creates a list.) var events = from ev in document.Descendants("item") select new { Title = (ev.Element("title").Value), Description = (ev.Element("description").Value), Link = (ev.Element("link").Value), }; Question is im not quite ure where to put the regex (once I work out how to use the regex properly! :-) )

  • Substitute User Controls on Failure

    - by Brian
    Recently, I had a user control I was developing throw an exception. I know what caused the exception, but this issue got me thinking. If I have a user control throw an exception for whatever reason and I wish to replace that usercontrol with something else (e.g. an error saying, "Sorry, this part of the page broke.") and perhaps log the error, what would be a good way to do it that could be done independently of what the user control is or does (i.e. I'm not saying what the user control does/is, because I want an answer where that is irrelevant). Code sample: <asp:TableRow VerticalAlign="Top" HorizontalAlign="Left"> <asp:TableCell> <UR:MyUserControl ID="MyUserControl3" runat="server" FormatString="<%$ AppSettings:RVUC %>" ConnectionString="<%$ ConnectionStrings:WPDBC %>" Title="CO" /> </asp:TableCell> <asp:TableCell> <UR:MyUserControl ID="MyUserControl4" runat="server" FormatString="<%$ AppSettings:RVUA %>" ConnectionString="<%$ ConnectionStrings:WPDBA %>" Title="IEAO" /> </asp:TableCell> </asp:TableRow>

  • Paypal Sandbox 2014 Non US test account Sign Up proper link

    - by Flood Gravemind
    Ok I had a Paypal Sandbox account a year ago. I am developing a new site for a client and when I try to Login it won't recognize my email address. I tried forgot my password forgot password still nothing. So I guessed that maybe due to inactivity for such a long time they may have deleted my account. So then I try to Sign Up for a new one. I entered my details 3 times now and spent 6 hours trying to figure out what is the proper link to do this. Then I went to another Sandbox link which required me to entered a US Zip code and its a dead end. I am not even sure which Paypal account I signed up for those three times. No email nothing at all. I am a Non US developer and the FAQ link for Non US developers just points to their REST API. Can someone please guide me to the proper Paypal Sandbox Setup for Non US developers including the proper sign up links please. And I know Stackoverflow does not like rants but from my experience dealing with Paypal, GTA 6 should make a satirical Paypal company in their next Game with Paypal Developer Rampage mode for the main protagonist who also happens to be a Developer. EDIT: REST API does not include UK :(

  • Why won't my code segfault on Windows 7?

    - by Trevor
    This is an unusual question to ask but here goes: In my code, I accidentally dereference NULL somewhere. But instead of the application crashing with a segfault, it seems to stop execution of the current function and just return control back to the UI. This makes debugging difficult because I would normally like to be alerted to the crash so I can attach a debugger. What could be causing this? Specifically, my code is an ODBC Driver (ie. a DLL). My test application is ODBC Test (odbct32w.exe) which allows me to explicitly call the ODBC API functions in my DLL. When I call one of the functions which has a known segfault, instead of crashing the application, ODBC Test simply returns control to the UI without printing the result of the function call. I can then call any function in my driver again. I do know that technically the application calls the ODBC driver manager which loads and calls the functions in my driver. But that is beside the point as my segfault (or whatever is happening) causes the driver manager function to not return either (as evidenced by the application not printing a result). One of my co-workers with a similar machine experiences this same problem while another does not but we have not been able to determine any specific differences.

The issue I am having, I call upon the function - However the code after the function call is continuing before the function has returned a value. Here is the function - function getData() { var myVar; var xmlLoc = $.get("http://ec.urbentom.co.uk/StudentAppData.xml", function(data) { $xml = $(data); myVar = $xml; console.log(myVar); console.log(String($xml)); localStorage.setItem("Data", $xml); console.log(String(localStorage.getItem("Data"))); return myVar; }); return myVar; console.log("Does this continue"); } And here is where it is called upon - $(document).on("pageshow","#Information",function() { $xml = $(getData()); //Here is the function call console.log($xml); //However, it will instantly go to this line before 'getData' has returned a value. $xml.find('AllData').each(function() { $(this).find('item').each(function() { if ($(this).find('Category').text()=="Facilities") { console.log($(this).find('Title').text()); //Do stuff here } else if ($(this).find('Category').text()=="Contacts" || $(this).find('Category').text()=="Information") { console.log($(this).find('Title').text()); //Do stuff here too } }); $('#informationList').html(output).listview().listview("refresh"); console.log("Finished"); }); }); Right now, I'm unsure of why it is not working. My guess is that it is because I am calling a function within a function. Does anyone have any ideas on how this issue can be fixed?
