  • Computer Flashes Out?

    - by GuyNoir
    We have a strange problem with our computers at my school. They are all Latitude 2100 Netbooks. At random points (I can't seem to find a pattern) the screen will turn a single color (red, green, black, brown, etc.) To fix this, the computer must be put to sleep, and brought back up. They have integrated graphics, but I can't imagine that if it was a bug with the computer itself, that every single computer would do this. Is there any way I could find out the problem that's causing this. Some diagnostic tool? Thanks. Edit: Forgot, they all have windows.

  • How to add a TabBar to NavigationController based iPhone app

    - by Alex
    I have a simple NavigationController based app. The main window shows a TableView and selecting an item loads a sub-view. I used Interface Builder for UI views. Now I want to add a TabBar to the app. Where do I put it? Do I need a TabBarController? Should it go in the MainWindow.xib, or RootViewController.xib? How do I tie it together with my NavigationController?

  • Add UIView behind UITableView in UITableViewController code

    - by Drew C
    I would like to use a fixed image as the background in a simple grouped table view in my iPhone program. Unfortunately, no matter what I do, the background is always solid white. I have followed several supposed solutions on this site and others to no avail. Here is the relavant code in the viewDidLoad method of the table view controller class (note, this code uses a solid blue color rather than an image for simplicity's sake): self.tableView.opaque = NO; self.tableView.backgroundColor = [UIColor clearColor]; UIView *backgroundView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)]; backgroundView.backgroundColor = [UIColor blueColor]; [self.tableView.window addSubview:backgroundView]; [backgroundView release]; I suspect that I am not positioning the backgroundView view in the right place. I have tried sendToBack:, bringToFront:, and others but I always just get a white background. Is it possible to do this from within the UITableViewController? Must I use Interface Builder?

  • where.exe does not find OpenSSL libs when %ProgramFiles% variable is used in the PATH environment variable

    - by Piotr Dobrogost
    I installed both 32bit and 64bit version of OpenSSL libs on Vista x64. The 32bit version was installed in c:\Program Files (x86)\OpenSSL and the 64bit version was installed in c:\Program Files\OpenSSL. Then I added the entry %ProgramFiles%\OpenSSL to the PATH environment variable. %ProgramFiles%\OpenSSL is expanded to c:\Program Files (x86)\OpenSSL for 32bit programs and it's expanded to c:\Program Files\OpenSSL for 64bit programs. The idea is to have 32bit programs use 32bit version of OpenSSL libs and 64bit programs use 64bit version. I wanted to check if this works by running 32bit cmd.exe and issuing where ssleay32.dll and then by running 64bit cmd.exe and issuing the same. However in both cases I get the error INFO: Could not find files for the given pattern(s). What's wrong? This is a follow up to Different PATH environment variable for 32bit and 64bit Windows - is it possible?

  • JAXB: Unmarshalling does not always populate certain classes?

    - by user278458
    Hello, I have a JAXB class generation problem I was hoping to get some help with. Here's the part of the XML that is the source of my problem... Code: <xs:complexType name="IDType"> <xs:choice minOccurs="0" maxOccurs="2"> <xs:element name="DriversLicense" minOccurs="0" maxOccurs="1" type="an..35" /> <xs:element name="SSN" minOccurs="0" maxOccurs="1" type="an..35" /> <xs:element name="CompanyID" minOccurs="0" maxOccurs="1" type="an..35" /> </xs:choice> </xs:complexType> <xs:simpleType name="an..35"> <xs:restriction base="an"> <xs:maxLength value="35" /> </xs:restriction> </xs:simpleType> <xs:simpleType name="an"> <xs:restriction base="xs:string"> <xs:pattern value="[ !-~]*" /> </xs:restriction> </xs:simpleType> ...now this will generate JAXBElement types due the the "choice" with a "maxOccurs 1" . I want to avoid those, so I did that by modifying the code to use a "Wrapper" element and move the maxOccurs up to a sequence tag as follows... Code: <xs:complexType name="IDType"> <xs:sequence maxOccurs="2"> <xs:element name=Wrapper> <xs:complexType> <xs:choice> <xs:element name="DriversLicense" minOccurs="0" maxOccurs="1" type="an..35" /> <xs:element name="SSN" minOccurs="0" maxOccurs="1" type="an..35" /> <xs:element name="CompanyID" minOccurs="0" maxOccurs="1" type="an..35" /> </xs:choice> </xs:complexType> </xs:element> </xs:sequence> </xs:complexType> <xs:simpleType name="an..35"> <xs:restriction base="an"> <xs:maxLength value="35" /> </xs:restriction> </xs:simpleType> <xs:simpleType name="an"> <xs:restriction base="xs:string"> <xs:pattern value="[ !-~]*" /> </xs:restriction> </xs:simpleType> For class generating, looks like it works great - the JAXB element is replaced with a list of wrappers as String (i.e. List ) and compiles fine. However, when I unmarshall the actual XML data into the generated classes the data in the wrapper class is not populated - yet JAXB does not throw an exception. My question is: Do I need to change the schema a different way to make this work? Or is there something I can add/change/delete to the generated code or annotations? Appreciate any help you can offer! Thanks.

  • Visual Studio error on valid SQL

    - by Sam
    I'm getting an annoying error in visual studio for SQL that executes fine. SELECT InvoiceLines.LineID, InvoiceLines.InvoiceID, InvoiceLines.Text, InvoiceLines.Rate, InvoiceLines.Count, InvoiceLines.Rate * InvoiceLines.Count AS LineTotal, ((InvoiceLines.Rate * InvoiceLines.Count) * (1 + Invoices.VatRate / 100)) * (1 - CAST(Invoices.Discount AS money) * InvoiceLines.ApplyDiscount / 100) AS LineTotalIncVat, InvoiceLines.ApplyDiscount FROM InvoiceLines LEFT JOIN Invoices ON Invoices.InvoiceID = InvoiceLines.InvoiceID What LineTotalIncVat is trying to do is compute the total for the invoice item while adding the vat and subtracting the discount, and yes, probably better to do this in code (would if I could) The error visual studio gives is: There was an error parsing the query [token line number =1, token line offset =14, token in error = InvoiceLines] Even though it will validate and execute without a problem in the query builder...

  • How is this modsec rule getting triggered?

    - by BipedalShark
    I made a GET request to the URL, http://domain.tld/test/docs/index.php?create_table=1&step=2 and got a 403 response code. It turns out this modsec rule is getting triggered: Access denied with code 403 (phase 2). Pattern match "(?:ogg|gopher|zlib|(?:ht|f)tps?)\:/" at ARGS:gltr_redir. [file "/opt/mod_security/10_asl_rules.conf"] [line "827"] [id "340153"] [rev "22"] [msg "Generic PHP code injection protection via ARGS 3"] [severity "CRITICAL"] I would assume ARGS refers to GET/POST data, but there's no gltr_redir in the query string. And, being a GET request, there's obviously no POST data. So how is this rule being triggered?

  • "Attach or Add an entity that is not new...loaded from another DataContext. This is not supported."

    - by sah302
    Similar error as other questions, but not quite the same, I am not trying to attach anything. What I am trying to do is insert a new row into a linking table, specifically UserAccomplishment. Relations are set in LINQ to User and Accomplishment Tables. I have a generic insert function: Public Function insertRow(ByVal entity As ImplementationType) As Boolean If entity IsNot Nothing Then Dim lcfdatacontext As New LCFDataContext() Try lcfdatacontext.GetTable(Of ImplementationType)().InsertOnSubmit(entity) lcfdatacontext.SubmitChanges() lcfdatacontext.Dispose() Return True Catch ex As Exception Return False End Try Else Return False End If End Function If you try and give UserAccomplishment the two appropriate objects this will naturally crap out if either the User or Accomplishment already exist. It only works when both user and accomplishment don't exist. I expected this behavior. What does work is simply giving the userAccomplishment object a user.id and accomplishment.id and populating the rest of the fields. This works but is kind of awkward to use in my app, it would be much easier to simply pass in both objects and have it work out what already exists and what doesn't. Okay so I made the following (please ignore the fact that this is horribly inefficient because I know it is): Public Class UserAccomplishmentDao Inherits EntityDao(Of UserAccomplishment) Public Function insertLinkerObjectRow(ByVal userAccomplishment As UserAccomplishment) Dim insertSuccess As Boolean = False If Not userAccomplishment Is Nothing Then Dim userDao As New UserDao() Dim accomplishmentDao As New AccomplishmentDao() Dim user As New User() Dim accomplishment As New Accomplishment() 'see if either object already exists in db' user = userDao.getOneByValueOfProperty("Id", userAccomplishment.User.Id) accomplishment = accomplishmentDao.getOneByValueOfProperty("Id", userAccomplishment.Accomplishment.Id) If user Is Nothing And accomplishment Is Nothing Then 'neither the user or the accomplishment exist, both are new so insert them both, typical insert' insertSuccess = Me.insertRow(userAccomplishment) ElseIf user Is Nothing And Not accomplishment Is Nothing Then 'user is new, accomplishment is not new, so just insert the user, and the relation in userAccomplishment' Dim userWithExistingAccomplishment As New UserAccomplishment(userAccomplishment.User, userAccomplishment.Accomplishment.Id, userAccomplishment.LastUpdatedBy) insertSuccess = Me.insertRow(userWithExistingAccomplishment) ElseIf Not user Is Nothing And accomplishment Is Nothing Then 'user is not new, accomplishment is new, so just insert the accomplishment, and the relation in userAccomplishment' Dim existingUserWithAccomplishment As New UserAccomplishment(userAccomplishment.UserId, userAccomplishment.Accomplishment, userAccomplishment.LastUpdatedBy) insertSuccess = Me.insertRow(existingUserWithAccomplishment) Else 'both are not new, just add the relation' Dim userAccomplishmentBothExist As New UserAccomplishment(userAccomplishment.User.Id, userAccomplishment.Accomplishment.Id, userAccomplishment.LastUpdatedBy) insertSuccess = Me.insertRow(userAccomplishmentBothExist) End If End If Return insertSuccess End Function End Class Alright, here I basically check if the supplied user and accomplishment already exists in the db, and if so call an appropriate constructor that will leave whatever already exists empty, but supply the rest of the information so the insert can succeed. However, upon trying an insert: Dim result As Boolean = Me.userAccomplishmentDao.insertLinkerObjectRow(userAccomplishment) In which the user already exists, but the accomplishment does not (the 99% typical scenario) I get the error: "An attempt has been made to Attach or Add an entity that is not new, perhaps having been loaded from another DataContext. This is not supported." I have debugged this multiple times now and am not sure why this is occuring, if either User or Accomplishment exist, I am not including it in the final object to try to insert. So nothing appears to be attempted to be added. Even in debug, upon insert, the object was set to empty. So the accomplishment is new and the user is empty. 1) Why is it still saying that and how can I fix it ..using my current structure 2) Pre-emptive 'use repository pattern answers' - I know this way kind of sucks in general and I should be using the repository pattern. However, I can't use that in the current project because I don't have time to refactor that due to my non existence knowledge of it and time constraints. The usage of the app is going to so small that the inefficient use of datacontext's and what have you won't matter so much. I can refactor it once it's up and running, but for now I just need to 'push through' with my current structure. Edit: I also just tested this when having both already exists, and only insert each object's IDs into the table, that works. So I guess I could manually insert whichever object doesn't exist as a single insert, then put the ids only into the linking table, but I still don't know why when one object exists, and I make it empty, it doens't work.

  • php/dos : How do you parse a regedit export file?

    - by phill
    My objective is to look for Company key-value in the registry hive and then pull the corresponding Guid and other keys and values following it. So I figured i would run the regedit export command and then parse the file with php for the keys I need. So after running the dos batch command >regedit /E "output.txt" "HKLM\System....\Company1" The output textfile seems to be in some kind of UNICODE format which isn't regex friendly. I'm using php to parse the file and pull the keys. Here is the php code i'm using to parse the file <?php $regfile = "output.txt"; $handle = fopen ("c:\\\\" . $regfile,"r"); //echo "handle: " . $file . "<br>"; $row = 1; while ((($data = fgets($handle, 1024)) !== FALSE) ) { $num = count($data); echo "$num fields in line $row: \n"; $reg_section = $data; //$reg_section = "[HKEY_LOCAL_MACHINE\SOFTWARE\TECHNOLOGIES\MEDIUS\CONFIG MANAGER\SYSTEM\COMPANIES\RECORD11]"; $pattern = "/^(\[HKEY_LOCAL_MACHINE\\\SOFTWARE\\\TECHNOLOGIES\\\MEDIUS\\\CONFIG MANAGER\\\SYSTEM\\\COMPANIES\\\RECORD(\d+)\])$/"; if ( preg_match($pattern, $reg_section )) { echo "<font color=red>Found</font><br>"; } else { echo "not found<br>"; echo $data . "<br>"; } $row++; } //end while fclose($handle); ?> and the output looks like this.... 1 fields in line 1: not found ÿþW?i?n?d?o?w?s? ?R?e?g?i?s?t?r?y? ?E?d?i?t?o?r? ?V?e?r?s?i?o?n? ?5?.?0?0? ? 1 fields in line 2: not found 1 fields in line 3: not found [?H?K?E?Y??L?O?C?A?L??M?A?C?H?I?N?E?\?S?O?F?T?W?A?R?E?\?I?N?T?E?R?S?T?A?R? ?T?E?C?H?N?O?L?O?G?I?E?S?\?X?M?E?D?I?U?S?\?C?O?N?F?I?G? ?M?A?N?A?G?E?R?\?S?Y?S?T?E?M?\?C?O?M?P?A?N?I?E?S?]? ? 1 fields in line 4: not found "?N?e?x?t? ?R?e?c?o?r?d? ?I?D?"?=?"?4?1?"? ? 1 fields in line 5: not found Any ideas how to approach this? thanks in advance

  • Lazy Tables app from iphone

    - by Warrior
    I am new to iphone development. I have parsed a youtube file and displaying its contents with the image in the table view. But the scrolling has become slower because of displaying image.So i want to display the image as the lazy tables program from apple docs.Since they have used navigation based application , their rootviewcontroller loads first and then the delegate class call the parsing ,and when they reload the table view, the contents are displayed. The data array count shows 25. I am using a view controller to display the tables on the present modal view, more over when i run my application, first delegate methods call the parsing. So when i click the youtube icon in my landing page it navigates to table view. So by this time data array count shows 0. I have created table view in interface builder and set the outlets to the file owner properly. Please help me out. I want to increasing the scrolling performance. Thanks.

  • Tough question on WPF, Win32, MFC

    - by Mack
    Let's suppose you're an IT student with a basic knowledge of C++ and C#. Let's suppose that you want to design apps that: need to deliver some performance like archivers, cryptographic algorithms, codecs make use of some system calls have a gui and you want to learn an Api that will enable you to write apps like those described earlier and: is mainstream is future proof entitles you to find a decent job is easy enough - I mean easy like VCL, not easy like winapi So, making these assumptions, what Api will you choose? MFC, WPF, other? I really like VCL and QT, but they're not mainstream and I think few employers will want you to write apps in QT or Visual C++ Builder... Thanks for answers.

  • Import CSV from url address and export as XML -- Rails

    Two questions: How can I import a file from a web address, without a form? Example: Organisation.import(:from = 'http://wufoo.com/report.csv') How can I use xml builder without pulling from the db? More Info My company uses wufoo for web forms. The data from wufoo is exported as csv files. To get the data into my company's cms, it needs to be formatted as xml. I don't need to store any of the data, aside from the url to the csv file. I thought this might work well as a simple rails app.

  • Search and replace global modifier

    - by mrucci
    Is there any reason why non-global/first-occurrence substitution is the default in many text editing programs (vim, sed, perl, etc.)? I am talking about the /g flag of search and replace commands like: :s/pan/focaccia/g # in vim sed 's/sfortuna/fortuna/g' # with sed that will substitute every occurrence of the search pattern with the replacement string. After (not too) many years of vim and sed usage I still did not find any use case for non-global substitutions. Is there some valid historical reason? Or it is because it is? Thanks.

  • How do I use constructor dependency injection to supply Models from a collection to their ViewModels

    - by GraemeF
    I'm using constructor dependency injection in my WPF application and I keep running into the following pattern, so would like to get other people's opinion on it and hear about alternative solutions. The goal is to wire up a hierarchy of ViewModels to a similar hierarchy of Models, so that the responsibility for presenting the information in each model lies with its own ViewModel implementation. (The pattern also crops up under other circumstances but MVVM should make for a good example.) Here's a simplified example. Given that I have a model that has a collection of further models: public interface IPerson { IEnumerable<IAddress> Addresses { get; } } public interface IAddress { } I would like to mirror this hierarchy in the ViewModels so that I can bind a ListBox (or whatever) to a collection in the Person ViewModel: public interface IPersonViewModel { ObservableCollection<IAddressViewModel> Addresses { get; } void Initialize(); } public interface IAddressViewModel { } The child ViewModel needs to present the information from the child Model, so it's injected via the constructor: public class AddressViewModel : IAddressViewModel { private readonly IAddress _address; public AddressViewModel(IAddress address) { _address = address; } } The question is, what is the best way to supply the child Model to the corresponding child ViewModel? The example is trivial, but in a typical real case the ViewModels have more dependencies - each of which has its own dependencies (and so on). I'm using Unity 1.2 (although I think the question is relevant across the other IoC containers), and I am using Caliburn's view strategies to automatically find and wire up the appropriate View to a ViewModel. Here is my current solution: The parent ViewModel needs to create a child ViewModel for each child Model, so it has a factory method added to its constructor which it uses during initialization: public class PersonViewModel : IPersonViewModel { private readonly Func<IAddress, IAddressViewModel> _addressViewModelFactory; private readonly IPerson _person; public PersonViewModel(IPerson person, Func<IAddress, IAddressViewModel> addressViewModelFactory) { _addressViewModelFactory = addressViewModelFactory; _person = person; Addresses = new ObservableCollection<IAddressViewModel>(); } public ObservableCollection<IAddressViewModel> Addresses { get; private set; } public void Initialize() { foreach (IAddress address in _person.Addresses) Addresses.Add(_addressViewModelFactory(address)); } } A factory method that satisfies the Func<IAddress, IAddressViewModel> interface is registered with the main UnityContainer. The factory method uses a child container to register the IAddress dependency that is required by the ViewModel and then resolves the child ViewModel: public class Factory { private readonly IUnityContainer _container; public Factory(IUnityContainer container) { _container = container; } public void RegisterStuff() { _container.RegisterInstance<Func<IAddress, IAddressViewModel>>(CreateAddressViewModel); } private IAddressViewModel CreateAddressViewModel(IAddress model) { IUnityContainer childContainer = _container.CreateChildContainer(); childContainer.RegisterInstance(model); return childContainer.Resolve<IAddressViewModel>(); } } Now, when the PersonViewModel is initialized, it loops through each Address in the Model and calls CreateAddressViewModel() (which was injected via the Func<IAddress, IAddressViewModel> argument). CreateAddressViewModel() creates a temporary child container and registers the IAddress model so that when it resolves the IAddressViewModel from the child container the AddressViewModel gets the correct instance injected via its constructor. This seems to be a good solution to me as the dependencies of the ViewModels are very clear and they are easily testable and unaware of the IoC container. On the other hand, performance is OK but not great as a lot of temporary child containers can be created. Also I end up with a lot of very similar factory methods. Is this the best way to inject the child Models into the child ViewModels with Unity? Is there a better (or faster) way to do it in other IoC containers, e.g. Autofac? How would this problem be tackled with MEF, given that it is not a traditional IoC container but is still used to compose objects?

  • How do I create something like a negated character class with a string instead of characters?

    - by Chas. Owens
    I am trying to write a tokenizer for Mustache in Perl. I can easily handle most of the tokens like this: #!/usr/bin/perl use strict; use warnings; my $comment = qr/ \G \{\{ ! (?<comment> .+? ) }} /xs; my $variable = qr/ \G \{\{ (?<variable> .+? ) }} /xs; my $text = qr/ \G (?<text> .+? ) (?= \{\{ | \z ) /xs; my $tokens = qr/ $comment | $variable | $text /x; my $s = do { local $/; <DATA> }; while ($s =~ /$tokens/g) { my ($type) = keys %+; (my $contents = $+{$type}) =~ s/\n/\\n/; print "type [$type] contents [$contents]\n"; } __DATA__ {{!this is a comment}} Hi {{name}}, I like {{thing}}. But I am running into trouble with the Set Delimiters directive: #!/usr/bin/perl use strict; use warnings; my $delimiters = qr/ \G \{\{ (?<start> .+? ) = [ ] = (?<end> .+?) }} /xs; my $comment = qr/ \G \{\{ ! (?<comment> .+? ) }} /xs; my $variable = qr/ \G \{\{ (?<variable> .+? ) }} /xs; my $text = qr/ \G (?<text> .+? ) (?= \{\{ | \z ) /xs; my $tokens = qr/ $comment | $delimiters | $variable | $text /x; my $s = do { local $/; <DATA> }; while ($s =~ /$tokens/g) { for my $type (keys %+) { (my $contents = $+{$type}) =~ s/\n/\\n/; print "type [$type] contents [$contents]\n"; } } __DATA__ {{!this is a comment}} Hi {{name}}, I like {{thing}}. {{(= =)}} If I change it to my $delimiters = qr/ \G \{\{ (?<start> [^{]+? ) = [ ] = (?<end> .+?) }} /xs; It works fine, but the point of the Set Delimiters directive is to change the delimiters, so the code will wind up looking like my $variable = qr/ \G $start (?<variable> .+? ) $end /xs; And it is perfectly valid to say {{{== ==}}} (i.e. change the delimiters to {= and =}). What I want, but maybe not what I need, is the ability to say something like (?:not starting string)+?. I figure I am just going to have to give up being clean about it and drop code into the regex to force it to match only what I want. I am trying to avoid that for four reasons: I don't think it is very clean. It is marked as experimental. I am not very familier with it (I think it comes down to (?{CODE}) and returning special values. I am hoping someone knows some other exotic feature that I am not familiar with that fits the situation better (e.g. (?(condition)yes-pattern|no-pattern)). Just to make things clear (I hope), I am trying to match a constant length starting delimiter followed by the shortest string that allows a match and does not contain the starting delimiter followed by a space followed by an equals sign followed by the shortest string that allows a match that ends with the ending delimiter.

  • Find workspace location using ANT

    - by ThunderChunky_SF
    I'm working on a build script in the Flash Builder version of Eclipse. This build script needs to import launch configuration .launch files into the user's workspace. However there doesn't seem to be an available ANT var for determining the workspace location. While stepping through the available vars with intellisense I noticed that ${osgi.instance.area} does point to my current workspace but when I tried to echo it back in a running ant script it just spat out "${osgi.instance.area}" and not the path. Any help would be greatly appreciated. Thank you!!!

  • Using a table-alias in Kohana queries?

    - by Aristotle
    I'm trying to run a simple query with $this->db in Kohana, but am running into some syntax issues when I try to use an alias for a table within my query: $result = $this->db ->select("ci.chapter_id, ci.book_id, ci.chapter_heading, ci.chapter_number") ->from("chapter_info ci") ->where(array("ci.chapter_number" => $chapter, "ci.book_id" => $book)) ->get(); It seems to me that this should work just fine. I'm stating that "chapter_info" ought to be known as "ci," yet this isn't taking for some reason. The error is pretty straight-forward: There was an SQL error: Table 'gb_data.chapter_info ci' doesn't exist - SELECT `ci`.`chapter_id`, `ci`.`book_id`, `ci`.`chapter_heading`, `ci`.`chapter_number` FROM (`chapter_info ci`) WHERE `ci`.`chapter_number` = 1 AND `ci`.`book_id` = 1 If I use the full table name, rather than an alias, I get the expected results without error. This requires me to write much more verbose queries, which isn't ideal. Is there some way to use shorter names for tables within Kohana's query-builder?

  • Run script when POST data is sent to Apache

    - by Nathan Adams
    Among my several years of running servers there seems to be a pattern with most spam activity. My question/idea is that is there a way to tell Apache to run a script when POST data is detected? What I would want to do is perform a reverse DNS lookup on the client's IP address, and then perform a DNS lookup on the hostname in the PTR record. Afterwards, perform some checks, excuse the pseudo-code: if PTR does not exist: deny POST request if IP of PTR hostname = client's IP Allow POST request else deny POST request Though I don't care about GET requests, even though they can be just as malicious, this idea is targeted towards spam comments which use POST data to send the comment data to the web server. In order to make sure there isn't much of a time delay, I would run my own recursive DNS server. Please do note, this isn't meant to be a sliver bullet to spam, but it should decrease the volume. Possible or impossible?

  • Table View rotate, but not properly (shape change)

    - by Pencrace
    Hello everyone, Here is the thing. I have a ViewController which contain a view in full window. And the program run in landscape mode. I want to put an UITableView over the full screen view but only on right half part of the screen. So I add a UITableView in my view controller, I used the Interface Builder in order to set the Table View in the upper half of the screen so It will be on the right part in LandscapeLeft mode. I searched for on a lot of forum how to rotate my Table View. And so it does... except, It get stuck on the upper half of the landscape mode, it should stick on the right half. I'm not a iPhone coder since long, so I'm a bit confused on how to solve this problem. Do you have any idea on how to resize or make the TableView rotate properly. Thanks,

  • Match over multiple lines perl regular expression

    Hi, I have a file like this: 01 00 01 14 c0 00 01 10 01 00 00 16 00 00 00 64 00 00 00 65 00 00 01 07 40 00 00 22 68 61 6c 2e 6f 70 65 6e 65 74 2e 63 6f 6d 3b 30 30 30 30 30 30 30 30 32 3b 30 00 00 00 00 01 08 40 00 00 1e 68 61 6c 2e 6f 70 65 6e 65 74 2d 74 65 6c 65 63 6f 6d 2e 6c 61 6e 00 00 00 00 01 28 40 00 00 21 72 65 61 6c 6d 31 2e 6f 70 65 6e 65 74 2d 74 65 6c 65 63 6f 6d 2e 6c 61 6e 00 00 00 00 00 01 25 40 00 00 1e 68 61 6c 2e 6f 70 65 6e 65 74 2d 74 65 6c 65 63 6f 6d 2e 6c 61 6e 00 00 00 00 01 1b 40 00 00 20 72 65 61 6c 6d 2e 6f 70 65 6e 65 74 2d 74 65 6c 65 63 6f 6d 2e 6c 61 6e 00 00 01 02 40 00 00 0c 01 00 00 16 00 00 01 a0 40 00 00 0c 00 00 00 01 00 00 01 9f 40 00 00 0c 00 00 00 00 00 00 01 16 40 00 00 0c 00 00 00 00 00 00 01 bb 40 00 00 28 00 00 01 c2 40 00 00 0c 00 00 00 00 00 00 01 bc 40 00 00 13 31 39 37 37 31 31 31 32 32 33 31 00 I am reading the file and then finding certain octets and replacing them with tags: while(<FH>){ $line =~ s/(00 00 00 64)/<incr4> /g; $line =~ s/(00 00 00 65)/<incr4> /g; $line =~ s/(30 30 30 30 30 32)/<incr6ascii:999999:0>/g; $line =~ s/(31 31 32 32 33 31)/<incr6ascii:999999:0>/g; print OUTPUT $line; # } So for example, 00 00 00 64 would be replaced by the tag. This was working fine, but it doesn't seem to able to match over multiple lines any more. For example the pattern 31 31 32 32 33 31 runs over multiple lines, and the regular expression doesn't seem to catch it. I tried using /m /s pattern modifiers to ignore new lines but they didn't match it either. The only way around it I can come up with, is to read the whole file into a string using: undef $/; my $whole_file = <FH>; my $line = $whole_file; $line =~ s/(00 00 00 64)/<incr4> /g; $line =~ s/(00 00 00 65)/<incr4> /g; $line =~ s/(30 30 30 30 30 32)/<incr6ascii:999999:0>/g; $line =~ s/(31 31 32 32 33 31)/<incr6ascii:999999:0>/g; print OUTPUT $line; This works, the tags get inserted correctly, but the structure of the file is radically altered. It is all dumped out on a single line. I would like to retain the structure of the file as it appears here. Any ideas as to how I might do this? /john

  • Sandcastle setup - Navigation to webpage was canceled.

    - by Prof Plum
    I am try to use Sandcastle Help File Builder, but can't quite get it to work. Here is what I have done: 1) installed the program; works like normal 2) enabled xml in the project I want documentation for that gets generated in the /bin 3) created a new sandcastle help file project 4) added the C# project as (its a WCF service in case that matters) a documentation service 5) ran the "build" to generate the help file 6) went to "documentation"/"view help file"/"view help file" in the GUI 7) The file opens and contains the appopriate "folders", but every page says "Navigation to the webpage was canceled" I have seen the xml file in the /bin and it contains all of my /// comments, so why are they not showing up in the help file? Any ideas?
