  • A Tkinter StringVar() Question

    - by Graham
    I would like to create a StringVar() that looks something like this: someText = "The Spanish Inquisition" #Here's a normal variable whose value I will change eventually TkEquivalent = StringVar() #and here's the StringVar() TkEquivalent.set(string(someText)) #and here I set it equal to the normal variable. When someText changes, this variable will too... HOWEVER: TkEquivalent.set("Nobody Expects " + string(someText)) If I do this, the StringVar() will no longer automatically update! How can I include that static text and still have the StringVar() update to reflect changes made to someText? Thanks for your help.

  • Do I need to declare all my JQuery prototypes in a JQueryStatic definition file with typescript?

    - by Marilou
    I have the following code: ///<reference path="../typescript/jquery.d.ts" /> function addThemePrototypes() { var templateSetup = new Array(); $.fn.addTemplateSetup = function(func, prioritary) { if (prioritary) { templateSetup.unshift(func); } else { templateSetup.push(func); } }; } When I try to add the following: $('a').addTemplateSetup( Into this same file I notice there is no intellisense and typescript does not seem to know about the addTemplateSetup prototype that I just added. Is this the correct way for it to work or do I always need to add things like the definition for addTemplateSetup to an JQueryStatic definition file and then include that?

  • JSF managed bean question

    - by Nitesh Panchal
    Hello, I have one page which uses <ui:insert> called master.xhtml which uses one managedbean named MasterBean.java and its of viewScoped. It calls webservice and has all useful data which will be useful in master.xhtml as well as page which is built using master.xhtml (which uses <ui:include>). When i visit data.xhtml (which uses template as master.xhtml) and which uses managed bean as DataBean.java which is also of view scoped, how do i use MasterBean? If i directly use #{Masterbean.property}, won't it create a new instance again? or will it use the bean which is already in view scope? Also how do i use MasterBean in DataBean in such a way that existing MasterBean's instance is used in DataBean. I don't want new instance of MasterBean in DataBean. Thanks in advance. If i am not clear please let me know.

  • Embarassing C++ question regarding const

    - by Neil Butterworth
    My comments on this answer got me thinking about the issues of constness and sorting. I played around a bit and reduced my issues to the fact that this code: #include <vector> int main() { std::vector <const int> v; } will not compile - you can't create a vector of const ints. I suppose I should have known this, but I've never needed to create such a thing before. However, it seems like a useful construct to me, and I wonder if there is any way round this problem - I want to add things to a vector (or whatever), but they should not be changed once added. There's probably some embarrassingly simple solution to this, but it's something I'd never considered before.

  • Best way to access a sqlite database file in a web service.

    - by rogernorling
    First question from me on stack overflow. I have created a java web application containing a web service using netbeans (I hope a web application were the correct choice). I use the web application as is with no extra frameworks. This web service use a sqlite JDBC driver for accessing a sqlite database file. My problem is that the file path end up incorrect when I try to form the JDBC connection string. Also, the working directory is different when deploying and when running JUnit tests. I read somewhere about including the file as a resource, but examples of this were nowhere to be seen. In any case, what is the best way to open the sqlite database, both when the web service is deployed and when I test it "localy"? I don't know much about web services, I just need it to work, so please, help me with the technicalities.

  • Apache crashes after installing mysqli

    - by Marco P.
    System: Apache 2.2 running on Windows 2008 Server with PHP 5.2.17 VC6 Thread-Safe as a Module and MySQL 5.5.17 - all working fine. After installing mysqli using the php package, Apache won't start anymore. There is no error message in the log. What I have tried: Make sure Windows PATH points to libmysql.dll: Yes, done. Make sure extension_dir points to the right point: Yes. Other extensions load fine. Try without mysqli: Yes, Apache loads fine then. Try without mysql: Yes, does not help. Test mysql itself: Restarts server! Overwrite libmysql: Yes, does not help. It seems to me that there is some general problem with MySql, but the DB server seems to be running fine. I'm really out of ideas of things I could try, so I'm desperate for any hints or tricks.

  • How do C++ header files work?

    - by PulpFiction
    Hi all. When I include some function from a header file in a C++ program, does the entire header file code get copied to the final executable or only the machine code for the specific function is generated. For example, if I call std::sort from the <algorithm> header in C++, is the machine code generated only for the sort() function or for the entire <algorithm> header file. I think that a similar question exists somewhere on Stack Overflow, but I have tried my best to find it (I glanced over it once, but lost the link). If you can point me to that, it would be wonderful.

  • Understanding Eager Loading & How to use it? (specific issue)

    - by Elliot
    I have the following relation in my rails app: genre - has many - authors authors - belong to genre and has many books books - belongs to authors and belongs to users (users can add books to the db) in my controller I have: @books=current_user.books(:include => [:author => :genre], :order => 'books.created_at DESC')--- -- In my controller I used to have: @authors = Author.All @genres = Genre.All etc. -- In my view I have @genres.each do |genre| @authors.each do |author| if author.genre_id == genre.id stuff end end end Now that I'm using eager loading, I can't imagine this is the best way to do this (nor does it work as I don't have the @ variables) - I was wondering if anyone could shed some light on how to approach this?

  • Substitute all matches with values in Ruby regular expression

    - by Lewisham
    Hi all, I'm having a problem with getting a Ruby string substitution going. I'm writing a preprocessor for a limited language that I'm using, that doesn't natively support arrays, so I'm hacking in my own. I have a line: x[0] = x[1] & x[1] = x[2] I want to replace each instance with a reformatted version: x__0 = x__1 & x__1 = x__2 The line may include square brackets elsewhere. I've got a regex that will match the array use: array_usage = /(\w+)\[(\d+)\]/ but I can't figure out the Ruby construct to replace each instance one by one. I can't use .gsub() because that will match every instance on the line, and replace every array declaration with whatever the first one was. .scan() complains that the string is being modified if you try and use scan with a .sub()! inside a block. Any ideas would be appreciated!

  • Multiple Inheritance Debates II: according to Stroustrup

    - by asksuperuser
    I know very well about the traditional arguments about why Interface Inheritance is prefered to multiple inheritance, there has been already a post here : http://stackoverflow.com/questions/191691/should-c-include-multiple-inheritance But according to Stroustrup the real reason why Microsoft and Sun decided to get rid off multiple inheritance is that they have vested interest to do so: instead of putting features in the languages, they put in frameworks so that people then become tied to their platform instead of people having the same capability at a language standard level. What do you think ? Why Sun and Microsoft consider developers too immature to just make the choice themselves ?

  • Change notification in CouchDB when a field is set

    - by PartlyCloudy
    Hi, I'm trying to get notifications in a CouchDB change poll as soon as pre-defined field is set or changed. I've already had a look at filters that can be used for filtering change events(db/_changes?filter=myfilter). However, I've not yet found a way to include this temporal information, because you can only get the current version of the document in this filter functions. Is there any possibility to create such a filter? If it does not work, I could export my field to a separate database and the only poll for changes in that db, but I'd prefer to keep together my data for obvious reasons. Thanks in advance!

  • Create a basic matrix in C (input by user !)

    - by DM
    Hi there, Im trying to ask the user to enter the number of columns and rows they want in a matrix, and then enter the values in the matrix...Im going to let them insert numbers one row at a time. How can I create such function ? #include<stdio.h> main(){ int mat[10][10],i,j; for(i=0;i<2;i++) for(j=0;j<2;j++){ scanf("%d",&mat[i][j]); } for(i=0;i<2;i++) for(j=0;j<2;j++) printf("%d",mat[i][j]); } This works for inputting the numbers, but it displays them all in one line... The issue here is that I dont know how many columns or rows the user wants, so I cant print out %d %d %d in a matrix form .. Any thoughts ? Thanks :)

  • Persistent UDP sessions on Android

    - by Wedgeski
    I have a client-server app which requires me to maintain a persistent session over UDP. The goal is to maintain a path from the server to the mobile Android device no matter what route it has to the internet (WiFi or mobile network). This is achieved using a proprietary, well-tested session-management protocol over UDP. I need the phone to be able to maintain, say, a five-minute keep-alive with the server at all times. Ideally I would like to do this without maintaining any wake-locks on the device. I don't want the screen to light up every time I send a UDP to the server, for example, and I don't want to have a damaging effect on battery usage. Has anyone addressed this problem?

  • ctype_alpha but allow spaces(php)

    - by helloo
    I was wondering if one can allow spaces in a textfield when checking it with ctype_alpha. Since ctype_alpha only allows alphabetical letters, I don't know how to let the user enter space in the field. I did try using ctype_space but that didn't work. I simply want the user to be able to type only alphabets and they have a choice to include spaces if they "wish." I hope I will not have to use regexp as I am very new to all of this and hope to learn it at a later date. Below is some of the code...Thank you. elseif (!ctype_alpha($fname)) { echo "Your name may only contain alphabetical letters"; }

  • Difference between SRC and HREF

    - by Vijey
    The SRC and HREF attributes are used to include some external entities like an image, a CSS file, a html file, any other web page or a javascript file. Is there a clear differentiation between SRC and HREF? where/when to use SRC or HREF? I think they can't be used interchangeably. I'm giving below few examples where these attributes are used: To refer a CSS file: href="cssfile.css" inside the link tag To refer a js file: src="myscript.js" inside the script tag To refer an image file: src="mypic.jpg" inside an image tag To refer another webpage: href="http://www.webpage.com" inside an anchor tag

  • Why I have to redeclare a virtual function while overriding [C++]

    - by Neeraj
    #include <iostream> using namespace std; class Duck { public: virtual void quack() = 0; }; class BigDuck : public Duck { public: // void quack(); (uncommenting will make it compile) }; void BigDuck::quack(){ cout << "BigDuckDuck::Quack\n"; } int main() { BigDuck b; Duck *d = &b; d->quack(); } Consider this code, the code doesn't compiles. However when I declare the virtual function in the subclass, then it compiles fine. The compiler already has the signature of the function which the subclass will override, then why a redeclaration is required? Any insights.
