  • Problem with array of elements of a structure type

    - by kobac
    I'm writing an app in Visual Studio C++ and I have problem with assigning values to the elements of the array, which is array of elements of structure type. Compiler is reporting syntax error for the assigning part of the code. Is it possible in anyway to assign elements of array which are of structure type? typedef struct { CString x; double y; } Point; Point p[3]; p[0] = {"first", 10.0}; p[1] = {"second", 20.0}; p[2] = {"third", 30.0};

  • PPTP VPN connection always connects successfully in Mac OS X/windows but drops after 2 minute in iPad or it doesn't connect al all!

    - by Farshid
    Dear Users, I've a big problem with using iPad's VPN connection. When I use the same VPN connection (PPTP) configuration parameters in my Mac OS X Snow Leopard or my windows XP (Bootcamp), it works flawlessly but when I define the same connection in my iPad, connection drops in about 1 or 2 minutes (some times) and most of the time, it Doesn't Connect at all. I'm using iPad 3G with iOS 4.2.1 and my iPad is not jail-broken. I've tried so hard to make it work in an stable manner but not found any solution yet. (I should have put encryption level to No-Encryption in Mac and Windows otherwise it won't connect in my desktop operating systems. It is a host-related issue and I'm binding to that). I'm sure there is no technical problem in my iPad's hardware and this problem also exists in my friend's iPad too. Our devices work perfectly with 3G and Wifi connections. Your answers are really appreciated.

  • Looking for marg_setValue fix in iPhoneOS

    - by John Smith
    I am trying to compile a library originally written for Cocoa. Things are good until it looks for the function marg_setValue(). It says there is a syntax error before char in marg_setValue(argumentList,argumentOffset,char,(char)lua_toboolean(state,luaArgument)); (it's talking about the third argument, not (char) ) I am trying to port LuaObjectiveCBridge to the iPhone. It has two choices, either using Runtime or Foundation. I have discovered there are some problems with foundation so I am trying runtime. But the compiler is not co-operating.

  • Trying to catch integrity error with sqlaclhemey

    - by Lostsoul
    I'm having problems with trying to catch a error. I'm using pyramid/sqlalchemy and made a sign up form with email as the primary key. The problem is when a duplicate email is entered it raises a IntegrityError, so I'm trying to catch that error and provide a message but no matter what I do I can't catch it(the error keeps appearing). try: new_user = Users(email, firstname, lastname, password) DBSession.add(new_user) return HTTPFound(location = request.route_url('new')) except IntegrityError: message1 = "Yikes! Your email already exists in our system. Did you forget your password?" I get the same message when I tried except exc.SQLAlchemyError (although I want to catch specific errors and not a blanket catch all). Is there something wrong with my python syntax? or is there something I need to do special in sqlalchemy to catch it?

    - by user437899
    Hi, iam looking for a datagrid which contains objects from my class. class user { string name; int ID; ... } i tried AutoGenerateColumns = true. this will add columns (name, ID, ... like the properties of my class) but i want a different design. not all attributes from the object shold be shown and the columnheader shouldn't be generated from the variablenames... if i build a custom. column-design, i cant add my objects / they will not be displayed. is it possible to define my own columns according to my objects/class. i read about databindings, but i have no idea how i can bind objects/classes in WPF. (in Visual Studio i cant choose my class as datacontext)

  • What is the proper way to declare a specialization of a template for another template type?

    - by Head Geek
    The usual definition for a specialization of a template function is something like this: class Foo { [...] }; namespace std { template<> void swap(Foo& left, Foo& right) { [...] } } // namespace std But how do you properly define the specialization when the type it's specialized on is itself a template? Here's what I've got: template <size_t Bits> class fixed { [...] }; namespace std { template<size_t Bits> void swap(fixed<Bits>& left, fixed<Bits>& right) { [...] } } // namespace std Is this the right way to declare swap? It's supposed to be a specialization of the template function std::swap, but I can't tell whether the compiler is seeing it as such, or whether it thinks that it's an overload of it or something.

  • Teaching a mainframe COBOL programmer Java?

    - by Jared
    I’m trying to help someone learn Java who’s only programming experience is COBOL on the mainframe. I was wondering if anyone knew any good resources for object oriented concepts. I learned how to program with C++ so just understand the theory behind basic OOP. I’m more concerned about a way to get the basic concepts across, such as encapsulation and inheritance rather then Java syntax. I think it’d be better to teach the concepts of OOP then a language rather then trying to cram both a new language and paradigm in at the same time. Does anyone have any resources or ideas that could help this person learn OOP followed by Java?

  • Efficiency of PHP arrays cast as objects?

    - by keithjgrant
    From what I understand, PHP objects are generally much faster than arrays. How is that efficiency affected if I'm typecasting to define stdClass objects on the fly: $var = (object)array('one' => 1, 'two' => 2); If the code doing this is deeply-nested, will I be better off explicitly defining $var as an objects instead: $var = new stdClass(); $var->one = 1; $var->two = 2; Is the difference negligible since I'll then be accessing $var as an object from there on, either way?

  • About the fix for the interference between Company mode and Yasnippet

    - by janoChen
    Emacs wiki says: Company does interfere with Yasnippet’s native behaviour. Here’s a quick fix: http://gist.github.com/265010 The code is the following: (define-key company-active-map "\t" 'company-yasnippet-or-completion) (defun company-yasnippet-or-completion () (interactive) (if (yas/expansion-at-point) (progn (company-abort) (yas/expand)) (company-complete-common))) (defun yas/expansion-at-point () "Tested with v0.6.1. Extracted from `yas/expand-1'" (first (yas/current-key))) I placed that code in my .emacs and the following message appeared: Warning (initialization): An error occurred while loading `c:/Documents and Settings/Alex.AUTOINSTALL.001/Application Data/.emacs.elc': Symbol's value as variable is void: company-active-map To ensure normal operation, you should investigate and remove the cause of the error in your initialization file. Start Emacs with the `--debug-init' option to view a complete error backtrace. Do I have to place the fix code inside a YASnippet's .el file? or in my .emacs (which throws me an error)?

  • PHP and Apache environment variables

    - by Simon
    Hello, I want to pass an environment variable in linux to apache on start up. export MYVAR=5 --I define my environment variable on the command line PassEnv MYVAR --set apache to import the variable in apache config file apachectl restart --when I restart apache I don't get an error message. However I have noticed that if I do not create the environment variable in my first step, I get a warning message, so must be working here echo $_SERVER['MYVAR'] --i try to access the environment variable within PHP but it is not defined I've observed that if I try to PassEnv an environment variable that already exits (one that I havn't created myself) it works fine. The SetEnv directive also works fine. I'd really like to pass an environment variable to apache on the fly without writing it in a file. Help much appreciated. I'm using CentOS, PHP5 and Apache2. Thanks.

  • C# - Dictionary with generic array as value

    - by alhazen
    In my class, I want to use a dictionary with the following declaration: Dictionary<string, T[]> Since the operations of my class are exactly the same for all generic types, I do not wish to define my class as generic (which means I would have to create a separate instance of my class for each generic type I insert into the dictionary ?). One alternative I'm attempting is to use Dictionary<string, object> instead: public void Add<T>(string str, T value) { // Assuming key already exists var array = (T[]) dictionary[str]; array[0] = value; } However, when iterating over the dictionary, how do I cast the object value back to an array ? foreach(string strKey in dictionary.Keys) { var array = (T[]) dictionary[strKey]; // How to cast here ? //... array[0] = default(T); } Thanks.

  • ASP.NET JavaScript File Embeded In DLL With GZIP

    - by Lee Hesselden
    We have several fairly large JavaScript files embedded into a single script resources DLL. This is then consumed by multiple projects by way of a reference and page includes via the ASP.NET script manager. This keeps things nice and neat within our ASP.NET pages and requires very little work to integrate into new projects. The problem is that some of these script files are quite larger (approx 100KB) and take time to download. By running minify on them before embedding this is reduced down a lot (around 70KB) but not enough. What we would like to do is GZIP the files before they are embedded. However, just gzipping the files causes syntax errors as the content is not unzipped. There is a content type "text/javascript" applied in AssemblyInfo when the resource is embedded but we can't find a way to specify content-encoding. Is there any way to make this work without having to write a httpmodule/handler (which would mean changing the config for all consuming projects)?

  • Binding Properties.Settings to Textbox fails

    - by user268098
    I would like to define a key & value in Settings.settings and bind the value by declaration in the XAML (not in the code behind by command). Here's what I've been trying in vain: Create a WPF project "Exp1" with Visual Studio Express 2010. Set one key named "TextFromSettings" to the value "Some Text from Setting". Add the attribute xmlns:p="clr-namespace:Exp1.Properties;assembly=Exp1" to the tag. Add Text="{Binding Path=TextFromSettings, Mode=TwoWay, Source={x:Static p:Settings.Default}}" to the tag Now, the preview window shows the text, however, the compiler fails: "Error 1 Cannot find the type 'Settings'. Note that type names are case sensitive." Where am I going wrong?

  • How can I use linq to build an object from 1 row of data?

    - by Hcabnettek
    Hi All, I have a quick linq question. I have a stored proc that should return one row of data. I would like to use a lambda to build an object. Here's what I'm currently doing which works, but I know I should be able to use First instead of Select except I can't seem to get the syntax correct. Can anyone straighten me out here? Thanks for any help. var location = new GeoLocationDC(); DataSet ds = db.ExecuteDataSet(dbCommand); if(ds.Tables[0].Rows.Count == 1) { var rows = ds.Tables[0].AsEnumerable(); var x = rows.Select( c => new GeoLocationDC { Latitude = Convert.ToInt32(c.Field<string>("LATITUDE")), Longitude = Convert.ToInt32(c.Field<string>("LONGITUDE")) }).ToList(); if(x.Count > 0 ) { location = x[0]; } Cheers, ~ck }

  • Do we really need a safe release macro?

    - by Ian1971
    Quite a lot of people seem to use a macro such as #define SAFE_RELEASE(X) [X release]; X = nil; (myself included). I've been reassessing why I am using it and wanted to canvas some opinion. The purpose (I think) for using this macro is so that if you were to accidentally use your object after releasing it then you won't get a bad access exception because objective-c will quite happily ignore it when the object is nil. It strikes me that this has the potential to mask some obscure bugs. Maybe it would actually be preferable for the program to crash when you try to use X again. That way during testing you can find the issue and improve the code. Does this macro encourage lazy programming? Thoughts?

  • How do I return the rows from an Oracle Stored Procedure using SELECT?

    - by Calanus
    I have a stored procedure which returns a ref cursor as follows: CREATE OR REPLACE PROCEDURE AIRS.GET_LAB_REPORT (ReportCurTyp OUT sys_refcursor) AS v_report_cursor sys_refcursor; report_record v_lab_report%ROWTYPE; l_sql VARCHAR2 (2000); BEGIN l_sql := 'SELECT * FROM V_LAB_REPORT'; OPEN v_report_cursor FOR l_sql; LOOP FETCH v_report_cursor INTO report_record; EXIT WHEN v_report_cursor%NOTFOUND; END LOOP; CLOSE v_report_cursor; END; I want to use the output from this stored procedure in another select statement like: SELECT * FROM GET_LAB_REPORT() but I can't seem to get my head around the syntax. Any ideas?

  • Lazy evaluation with ostream C++ operators

    - by SavinG
    I am looking for a portable way to implement lazy evaluation in C++ for logging class. Let's say that I have a simple logging function like void syslog(int priority, const char *format, ...); then in syslog() function we can do: if (priority < current_priority) return; so we never actually call the formatting function (sprintf). On the other hand, if we use logging stream like log << LOG_NOTICE << "test " << 123; all the formating is always executed, which may take a lot of time. Is there any possibility to actually use all the goodies of ostream (like custom << operator for classes, type safety, elegant syntax...) in a way that the formating is executed AFTER the logging level is checked ?

  • js regexp problem

    - by Alexander
    I have a searching system that splits the keyword into chunks and searches for it in a string like this: var regexp_school = new RegExp("(?=.*" + split_keywords[0] + ")(?=.*" + split_keywords[1] + ")(?=.*" + split_keywords[2] + ").*", "i"); I would like to modify this so that so that I would only search for it in the beginning of the words. For example if the string is: "Bbe be eb ebb beb" And the keyword is: "be eb" Then I want only these to hit "be ebb eb" In other words I want to combine the above regexp with this one: var regexp_school = new RegExp("^" + split_keywords[0], "i"); But I'm not sure how the syntax would look like. I'm also using the split fuction to split the keywords, but I dont want to set a length since I dont know how many words there are in the keyword string. split_keywords = school_keyword.split(" ", 3); If I leave the 3 out, will it have dynamic lenght or just lenght of 1? I tried doing a alert(split_keywords.lenght); But didnt get a desired response

  • Is there any short way to load data to the properties of a class, for each column name matching the properties of the class?

    - by Ugur Gümüshan
    I want to load data to an instance of an object using its constructor and I write $this->property=$row["colname"] each time for each property. the mysql_fetch_object function fetches the data as an object but I am not sure if the instance of an object can be assigned to some object from inside. othwerwise I would use __construct($object) { $this=$object; } //doesn't give any syntax error Maybe I should look into iteration of properties and use foreach($object as $key => $value) $value=$object[$key]; or can I assign like $this=$object; within the constructor?

  • car and cdr in Scheme are driving me crazy ...

    - by kristian Roger
    Hi Im facing a problem with the car and cdr functions for example: first I defined a list called it x (define x (a (bc) d ( (ef) g ) )) so x now is equal to (a (bc) d ( (ef) g ) ) now for example I need to get the g from this list using only car and cdr (!! noshortcuts as caddr cddr !!) the correct answer is: (car(cdr(car(cdr(cdr(cdr x)))))) BUT how ? :-( I work according to the rules (the car gives the head of list and cdr gives the tail) and instead of getting the answer above I keep reaching wrong answers. Can any one help me in understanding this ... give me step or a way to solve it step by step Thanks in advance. I'm really sick of Scheme.

  • How does Mach-O loader recognize a bunch of NSString objects?

    - by overboming
    I have known that If you define a bunch of @"" NSString objects in the source code in Mac OS. These NSStrings will be stored in a segment in the Mach-O library. Section sectname __ustring segname __TEXT addr 0x000b3b54 size 0x000001b7 offset 731988 align 2^1 (2) reloff 0 nreloc 0 flags 0x00000000 reserved1 0 reserved2 0 If I hex dump the binary, they are aligned closely one by one with a 0x0000as separator. What I want to know is how does the loader in Mac OS X load these NSStrings when the program runs? Are they loaded simpily by recognize the 0x0000 separator or these is a string offset table elsewhere in the binary pointing to separate NSString objects? Thanks. (What I really want to do is the increase the length of one of the NSString, so I have to know how the loader recognize these separate objects)
