  • Is there a better way than #if DebugMode for logging

    - by Daniel
    I'm making a c++ library thats going to be P/Invoked from c#, so i am unable to breakpoint/debug the c++ side of things. So i decided to add logging so i can see if anything goes wrong and where it happens. I add a #define DebugMode 1 in order to determine if i am to log or not. First of all i'm not very good at c++ but i know enough to get around. So my questions are: Is there a better way than wrapping #if DebugMode #endifs around every Log call? I could simply do that inside the method and just return if logging isn't disabled but won't that mean then all those logging strings will be in the assembly? How can i emulate what printf does with its "..." operator enabling me to pass something like Log("Variable x is {0}", x); Thanks!

  • Select elements based on class and element type

    - by Beau Martínez
    How can I select all elements within an HTML document with a specific class and specific element type? I'm trying to select all anchors with the class title loggedin from an HTML document (and then open them within the browser). These are within parragraphs with the class title. They are leafs in the following DOM tree: + body + div class='content' + div id='siteTable' class='sitetable linklisting' + div class='thing id-t3_xxxx xxx xxx link' + div class='entry unvoted' + p class='title' + a class='title loggedin ' Where x indicates variable content. (I'm looking to do this in raw JavaScript, ie, not in jQuery.)

  • Is there any benefit to declaring a private property with a getter and setter?

    - by AmoebaMan17
    I am reviewing another developer's code and he has written a lot of code for class level variables that is similar to the following: /// <summary> /// how often to check for messages /// </summary> private int CheckForMessagesMilliSeconds { get; set; } /// <summary> /// application path /// </summary> private string AppPath { get; set; } Doesn't coding this way add unnecessary overhead since the variable is private? Am I not considering a situation where this pattern of coding is required for private variables?

  • performing a javascript event without triggering that event handler

    - by bento
    In my latest code, I have an event handler for a focus on a textarea. When the user clicks on the textarea, that event-handler is triggered which sets some other DOM states based on the selected textarea. However, elsewhere in my program I want to programmatically set the focus of the textarea without triggering that event handler. I know Backbone, for instance, has a way to silently perform an action. My only pseudo-solution is to temporarily set a variable: var silence = true; And then, in my event handler, only perform the logic if silence is false. The handler is still triggered, but the logic doesn't run. Does anyone else know of better strategies for this?

  • Best way to get an Application Context into a static method in Android

    - by Slapout
    I'm working on an Android application that has several Activities. In it I have a class with several static methods. I would like to be able to call these methods from the different Activities. I'm using the static methods to load data from an xml file via a XmlResourceParser. To create a XmlResourceParser requires a call on the Application Context. So my question is, what is the best way to get a reference to the Application Context into the static methods? Have each Activity get it and pass it in? Store it somehow in a global variable?

  • golang dynamically parsing files

    - by Brian Voelker
    For parsing files i have setup a variable for template.ParseFiles and i currently have to manually set each file. Two things: How would i be able to walk through a main folder and a multitude of subfolders and automatically add them to ParseFiles so i dont have to manually add each file individually? How would i be able to call a file with the same name in a subfolder because currently I get an error at runtime if i add same name file in ParseFiles. var templates = template.Must(template.ParseFiles( "index.html", // main file "subfolder/index.html" // subfolder with same filename errors on runtime "includes/header.html", "includes/footer.html", )) func main() { // Walk and ParseFiles filepath.Walk("files", func(path string, info os.FileInfo, err error) { if !info.IsDir() { // Add path to ParseFiles } return }) http.HandleFunc("/", home) http.ListenAndServe(":8080", nil) } func home(w http.ResponseWriter, r *http.Request) { render(w, "index.html") } func render(w http.ResponseWriter, tmpl string) { err := templates.ExecuteTemplate(w, tmpl, nil) if err != nil { http.Error(w, err.Error(), http.StatusInternalServerError) } }

  • About enumerations in Delphi and c++ in 64-bit environments

    - by sum1stolemyname
    I recently had to work around the different default sizes used for enumerations in Delphi and c++ since i have to use a c++ dll from a delphi application. On function call returns an array of structs (or records in delphi), the first element of which is an enum. To make this work, I use packed records (or aligned(1)-structs). However, since delphi selects the size of an enum-variable dynamically by default and uses the smallest datatype possible (it was a byte in my case), but C++ uses an int for enums, my data was not interpreted correctly. Delphi offers a compiler switch to work around this, so the declaration of the enum becomes {$Z4} TTypeofLight = ( V3d_AMBIENT, V3d_DIRECTIONAL, V3d_POSITIONAL, V3d_SPOT ); {$Z1} My Questions are: What will become of my structs when they are compiled on/for a 64-bit environment? Does the default c++ integer grow to 8 Bytes? Are there other memory alignment / data type size modifications (other than pointers)?

  • When exactly does a method have side effects?

    - by Kim
    As I always understood it, any change to the programs state (or anything to do with IO) is a side effect. It does not matter, whether the change occurs in a global variable or in a private field of the object the method is called on. It follows that all methods which do not return anything either do nothing at all or have a side effect. My confusion comes from one of our university's instructors (who is still a student and thus not omniscient yet;) ) telling me setters don't have side effects.

  • Read out result of a PageMethod into a jQuery-script

    - by Jan-Frederik Carl
    Hello, I am quite a jQuery novice and try to read out the result of a PageMethod into my jQuery script. I have a ScriptManager installed and the following WebMethod: [WebMethod(EnableSession = true)] public static string CheckSystemDefault(string _id) { int id = Convert.ToInt16(_id); addressTypeRepository = new AddressTypeRepository(); AddressType addressType = addressTypeRepository.GetById(id); if (addressType.IsSystemDefault == true) return "IsSystemDefault"; else return "IsNotSystemDefault"; } I use this to check if an object has the property IsSystemDefault. In the script, I hand over the id from the url and want to evaluate the result: var id = $(document).getUrlParam("id"); var check = PageMethods.CheckSystemDefault(id); if (check == "IsSystemDefault") { ... } if (check == "IsNotSystemDefault") { ... } But as a result, the variable "check" is undefined. What do I have to change?

  • Why is this variables declared as private and also readonly?

    - by Sergio Tapia
    In the following code: public class MovieRepository : IMovieRepository { private readonly IHtmlDownloader _downloader; public MovieRepository(IHtmlDownloader downloader) { _downloader = downloader; } public Movie FindMovieById(string id) { var idUri = ...build URI...; var html = _downloader.DownloadHtml(idUri); return ...parse ID HTML...; } public Movie FindMovieByTitle(string title) { var titleUri = ...build URI...; var html = _downloader.DownloadHtml(titleUri); return ...parse title HTML...; } } I asked for something to review my code, and someone suggested this approach. My question is why is the IHtmlDownloader variable readonly?

  • Marshal managed string[] to unmanaged char**

    - by Vince
    This is my c++ struct (Use Multi-Byte Character Set) typedef struct hookCONFIG { int threadId; HWND destination; const char** gameApps; const char** profilePaths; } HOOKCONFIG; And .Net struct [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Auto)] public struct HOOKCONFIG { public int threadId; public IntPtr destination; // MarshalAs? public string[] gameApps; // MarshalAs? public string[] profilePaths; } I got some problem that how do I marshal the string array? When I access the struct variable "profilePaths" in C++ I got an error like this: An unhandled exception of type 'System.AccessViolationException' occurred in App.exe Additional information: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. MessageBox(0, cfg.profilePaths[0], "Title", MB_OK); // error ... Orz

  • What are the characteristics of spaghetti code?

    - by justjoe
    Somebody said that when your PHP Code and application use global variable then it must be a spaghetti code (i assume this). I use wordpress a lot.

  • How can I access variables outside of current scope in javascript?

    - by sekmet64
    I'm writing some application in javascript and cannot figure it out how to access the variables declared in my function, inside this jquery parse. Inside I can access global variables, but I don't really want to create global vars for these values. Basically I want to extract file names from an xml document in the simulationFiles variable. I check if the node attribute is equal with the simName and extract the two strings inside the xml elements, that part I think it's working. How can I extract those xml elements and append them to local variables? function CsvReader(simName) { this.initFileName = "somepath"; this.eventsFileName = "somepath"; $(simulationFiles).find('simulation').each(function() { if ($(this).attr("name") == simName) { initFileName += $(this).find("init").text(); eventsFileName += $(this).find("events").text(); } }); }

  • How are exceptions allocated on the stack caught beyond their scope?

    - by John Doe
    In the following code, the stack-based variable 'ex' is thrown and caught in a function beyond the scope in which ex was declared. This seems a bit strange to me, since (AFAIK) stack-based variables cannot be used outside the scope in which they were declared (the stack is unwound). void f() { SomeKindOfException ex(...); throw ex; } void g() { try { f(); } catch (SomeKindOfException& ex) { //Handling code... } } I've added a print statement to SomeKindOfException's destructor and it shows that ex is destructed once it goes out of scope in f() but then it's caught in g() and destructed again once it goes out of scope there as well. Any help?

  • Compare output of program to correct program using bash script, without using text files

    - by Doug
    I've been trying to compare the output of a program to known correct output by using a bash script without piping the output of the program to a file and then using diff on the output file and a correct output file. I've tried setting the variables to the output and correct output and I believe it's been successful but I can't get the string comparison to work correctly. I may be wrong about the variable setting so it could be that. What I've been writing: TEST=`./convert testdata.txt < somesampledata.txt` CORRECT="some correct output" if [ "$TEST"!="$CORRECT" ]; then echo "failed" fi

  • How to tell when my batch of EAP calls are completed?

    - by codemonkie
    This is following my question: http://stackoverflow.com/questions/2607038/c-how-to-consume-web-service-adheres-to-the-event-based-asynchronous-pattern My program is calling the DoStuffAsync() x many times in a batch, hence the callback will get invoked the same number of times upon OnComplete(). Is there a way to find out when my batch is finished such that I can generate a report on the success/failed results? All I can think of is to have a static count variable for x and deduct 1 every time OnComplete() is called, but its kind of silly and error prone I'm afraid. TIA.

  • authentication in PHP ?

    - by user296516
    Hi guys, I need to make an authentication script in php. I have already made a login.php page, where the user can enter his unsername/password and it gets checked against a database. If the unsername/password are correct, the user should be forwarded to members.php page together with a $_SERVER['username'] variable. What is the command in PHP to go to another webpage, in this case members.php ? in pseudocode I see it like this: if ( unsername/password are OK ) { $_SERVER['username'] = $username; goto(members.php); } Thanks!

  • How to initialize an std::string using ""?

    - by Mohsin
    I'm facing problems with initializing a std::string variable using "" (i.e. an empty string). It's causing strange behavior in code that was previously working. Is the following statement wrong? std::string operationalReason = ""; When I use the following code everything works fine: std::string operationalReason; operationalReason.clear(); I believe that string literals are stored in a separate memory location that is compiler-dependent. Could the problem I'm seeing actually be indicating a corruption of that storage? If so, it would get hidden by my usage of the clear() function. Thanks.

  • Adding objects to LDAP via CGI

    - by musashiXXX
    I have a web form that collects information and submits it to a cgi that attempts to insert the data into LDAP. The problem is that I'm trying to use a variable with ::ldap::add and it's just not working. Here's the code: if {[string length env(QUERY_STRING)] != 0} { set handle [::ldap::connect localhost] set dn "cn=admin,dc=mycompany,dc=com" set pw "myPassword" ::ldap::bind $handle $dn $pw set dn "cn=[ncgi::value givenName] [ncgi::value sn],ou=people,dc=mycompany,dc=com" set formValues [ puts "cn {{[ncgi::value givenName] [ncgi::value sn]}}" puts "displayName [ncgi::value givenName] [ncgi::value sn]" foreach {key value} [ncgi::nvlist] { if {[string length $value] != 0} { puts "$key $value" } } puts "objectClass top" puts "objectClass person" puts "objectClass organizationalPerson" puts "objectClass inetOrgPerson" ] ::ldap::add $handle $dn { $formValues } ldap::unbind $handle } However, if I replace $formValues with the actual entries that I want to insert into LDAP, they get added just fine. I'm new to TCL so I wouldn't be surprised if there were some glaring errors in this snippet. Thanks in advance!
