  • wordpress categories and their subcategories

    - by Ayrton
    Hi I'm looking to obtain all the (parent) categories with their children accordingly (assuming you don't have grandchildren) and make the following structure <div class="box"> <h3><a href="#">Parent Category I</a></h3> <ul> <li><a href="#">sub cat 1</a></li> <li><a href="#">sub cat 2</a></li> <li><a href="#">sub cat 3</a></li> </ul> </div> <div class="box"> <h3><a href="#">Parent Category II</a></h3> <ul> <li><a href="#">sub cat 1</a></li> <li><a href="#">sub cat 2<</a></li> <li><a href="#">sub cat 3</a></li> </ul> </div> I figured it's something like (don't mind the syntax) however I don't know how to obtain those (parent)categories and their children: $parents = ... ; foreach($parents as $parent){ <div> <h3>$parent</h3> $children = ...; <ul> foreach ($children as $child){ <li>$child</li> } </ul> </div> }

  • Best way to organize filetype settings in .vim and .vimrc?

    - by dimatura
    I'm going through my vim dotfiles to tidy them up. I've noticed that through time I've added various filetype specific settings in various inconsistent ways. Let's suppose I'm customizing for Python: au BufRead,BufNewfFile *.py (do something). I don't like this because some Python files might not have the .py termination. au FileType python (do something). This seems a better option because it doesn't depend on the file having the .py termination. The drawback is that Vim doesn't know about some filetypes. I can make Vim recognize additional filetypes, but I also have various inconsistent ways of doing it: a .vim/filetype.vim file, another in .vim/after/filetype.vim and various set filetype commands in .vimrc. Add a .vim/ftplugin/python.vim file with filetype specific settings. I understand the $VIMRUNTIME/ftplugin/python.vim can override whatever settings I make here. One problem is that I'm not sure how this interacts with .vim/filetype.vim and .vim/after/filetype.vim. Add a .vim/after/ftplugin/python.vim. I understand that this is loaded after $VIMRUNTIME/ftplugin/python.vim so it can overwrite settings from there. As in the previous method I'm not sure how it interacts with the filetype.vim files. So I have at least four ways of doing this, not mentioning syntax files and filetype-specific plugins. It seems to me the best way to do this is to put my filetype specific settings in after/ftplugin so they don't get overwritten, and filetypes.vim in after for the same reason. However, before I proceed I'd like to ask if anyone has suggestions about the best way to deal with filetype specific settings.

  • Row Source - combo box, filtering what pops up in a combo box by date

    - by primus285
    so I have a combo box that I want to pop up when somebody wants to search by year. It will allow them to see in that combo box only results that happened in a certain year. so far I have something like SELECT DISTINCT Database_New.ASEC FROM Database_New WHERE (((Database_New.Date) >= DateValue('01/01/2001') AND (((Database_New.Date) <= DateValue('12/031/2001'))); or SELECT DISTINCT Database_New.ASEC FROM Database_New WHERE (((Database_New.Date) >= BETWEEN DateValue('01/01/2001') AND DateValue('12/31/2001’))); as you can see, the kicker is that I am already sorting the thing with SELECT DISTINCT under the ASEC field. But I want to filter it one more by year so a whole bunch of ASEC values that didnt happen in that year (and there are quite a few that happen rarely, or would onyl be associeted with one year) do not pop up as avalible. so far I get an error like "Syntax error in query expression '(((Database_New.Date) = DateValue('01/01/2001') AND (((Database_New.Date) <= DateValue('12/031/2001')))' and I am a VBA person, not quite as good at debuggin SQL. Is it something easy? or will it simply not work the way I have it set up.

  • Trying to modify the text of a document onkeydown is inserting text incorrectly.

    - by Benny
    I have the following html: <html> <head> <script> function myKeyDown() { var myDiv = document.getElementById('myDiv'); myDiv.innerHTML = myDiv.innerHTML.replace(/(@[a-z0-9_]+)/gi, '<strong>$1</strong>'); } function init() { document.addEventListener('keydown', myKeyDown, false); document.designMode = "on"; } window.onload = init; </script> </head> <body> <div id="myDiv"> This is my variable name: @varname. If I type here things go wrong... </div> </body> </html> My goal is to do a kind of syntax highlighting on edit, to highlight variable names that begin with an @ symbol. However, when I edit the document's body, the function runs but the cursor is automatically shifted to the beginning of the body before the keystroke is performed. My hypothesis is that the keypress event is trying to insert the new character at a specified index, but when I run the replace function the indices get messed up so it defaults the character insertion point to the beginning. I'm using Firefox to test by the way. Any help would be appreciated. Thanks, B.J.

  • Why do pure virtual base classes get direct access to static data members while derived instances do

    - by Shamster
    I've created a simple pair of classes. One is pure virtual with a static data member, and the other is derived from the base, as follows: #include <iostream> template <class T> class Base { public: Base (const T _member) { member = _member; } static T member; virtual void Print () const = 0; }; template <class T> T Base<T>::member; template <class T> void Base<T>::Print () const { std::cout << "Base: " << member << std::endl; } template <class T> class Derived : public Base<T> { public: Derived (const T _member) : Base<T>(_member) { } virtual void Print () const { std::cout << "Derived: " << this->member << std::endl; } }; I've found from this relationship that when I need access to the static data member in the base class, I can call it with direct access as if it were a regular, non-static class member. i.e. - the Base::Print() method does not require a this- modifier. However, the derived class does require the this-member indirect access syntax. I don't understand why this is. Both class methods are accessing the same static data, so why does the derived class need further specification? A simple call to test it is: int main () { Derived<double> dd (7.0); dd.Print(); return 0; } which prints the expected "Derived: 7"

  • Enter ID instead of name on submit (form)

    - by Derek
    In my activities table, I have a user ID and a project ID. When a user (of admin level) creates an activity they select from a drop down menu a project. Here is the select query to draw up appropriate values: $sql = "SELECT usersprojects_tb.projectid, projects.projectname FROM projects INNER JOIN usersprojects on projects.projectid = usersprojects.projectid WHERE usersprojects.userid = '".$_SESSION['SESS_USERID']."'"; And for the tag with the dropdown menu, I have this: <?php echo $row['projectname']?> I have tried submitting the form with 'projectid' here instead and the project ID is stored successfully in my activies table. However, the user needs to see the project names (IDs arent exactly user-friendly!) And with 'projectname' as displayed, they can select the names of the available projects (to associate an activity with) but the project ID is not stored, how I link this up, so that when the project name is sent, the ID for this project is stored properly in my activities table. I'm also having the exact same problem with the users drop down. As the admin user selects a user from the drop down to assign the task to. I exactly what I want, but I think I may be using the wrong syntax! Any help is much appreciated. Thanks.

  • How to mark array value types in PHP (Java)Doc?

    - by Christian Sciberras
    It might be a bit difficult to explain, so I'll give some example code. Note that I'm using NetBeans IDE (latest). class Dummy { public function say(){ } } /** * Builds dummy class and returns it. * @return Dummy The dummy class. */ function say_something(){ return new Dummy(); } $s=say_something(); While developing in netbeans I can invoke auto-complete by hitting ctrl+space after typing "$s-". In the the hint window that follows, there is the item "say()". This is because the javadoc says say_something returns a Dummy and NetBeans parsed Dummy class to know that it has a method called "say()". So far so good. My problem is with arrays. Example code follows: /** * Builds array of 2 dummy classes and returns it. * @return Array The dummy class. (*) */ function say_something2(){ return array(new Dummy(),new Dummy()); } $s=say_something2(); If I try the auto-complete thing again but with "$s[0]-" instead, I don't get the methods fro Dummy class. This is because in the JavaDoc I only said that it is an array, but not the values' type. So the question would be, is there any JavaDoc syntax, cheat, whatever which allows me to tell JavaDoc what type of variables to expect in an array?

  • Oracle why does creating trigger fail when there is a field called timestamp?

    - by Omar Kooheji
    I've just wasted the past two hours of my life trying to create a table with an auto incrementing primary key bases on this tutorial, The tutorial is great the issue I've been encountering is that the Create Target fails if I have a column which is a timestamp and a table that is called timestamp in the same table... Why doesn't oracle flag this as being an issue when I create the table? Here is the Sequence of commands I enter: Creating the Table: CREATE TABLE myTable (id NUMBER PRIMARY KEY, field1 TIMESTAMP(6), timeStamp NUMBER, ); Creating the Sequence: CREATE SEQUENCE test_sequence START WITH 1 INCREMENT BY 1; Creating the trigger: CREATE OR REPLACE TRIGGER test_trigger BEFORE INSERT ON myTable REFERENCING NEW AS NEW FOR EACH ROW BEGIN SELECT test_sequence.nextval INTO :NEW.ID FROM dual; END; / Here is the error message I get: ORA-06552: PL/SQL: Compilation unit analysis terminated ORA-06553: PLS-320: the declaration of the type of this expression is incomplete or malformed Any combination that does not have the two lines with a the word "timestamp" in them works fine. I would have thought the syntax would be enough to differentiate between the keyword and a column name. As I've said I don't understand why the table is created fine but oracle falls over when I try to create the trigger... CLARIFICATION I know that the issue is that there is a column called timestamp which may or may not be a keyword. MY issue is why it barfed when I tried to create a trigger and not when I created the table, I would have at least expected a warning. That said having used Oracle for a few hours, it seems a lot less verbose in it's error reporting, Maybe just because I'm using the express version though. If this is a bug in Oracle how would one who doesn't have a support contract go about reporting it? I'm just playing around with the express version because I have to migrate some code from MySQL to Oracle.

  • How can I change some specific carps into croaks in Perl?

    - by sid_com
    I tried to catch a carp-warning: carp "$start is > $end" if (warnings::enabled()); ) with eval {} but it didn't work, so I looked in the eval documentation and I discovered, that eval catches only syntax-errors, run-time-errors or executed die-statements. How could I catch a carp warning? #!/usr/bin/env perl use warnings; use strict; use 5.012; use List::Util qw(max min); use Number::Range; my @array; my $max = 20; print "Input (max $max): "; my $in = <>; $in =~ s/\s+//g; $in =~ s/(?<=\d)-/../g; eval { my $range = new Number::Range( $in ); @array = sort { $a <=> $b } $range->range; }; if ( $@ =~ /\d+ is > \d+/ ) { die $@ }; # catch the carp-warning doesn't work die "Input greater than $max not allowed $!" if defined $max and max( @array ) > $max; die "Input '0' or less not allowed $!" if min( @array ) < 1; say "@array";

  • How to nest joins with CakePHP?

    - by Daren Thomas
    I'm trying to behave. So, instead of using following SQL syntax: select * from tableA INNER JOIN tableB on tableA.id = tableB.tableA_id LEFT OUTER JOIN ( tableC INNER JOIN tableD on tableC.tableD_id = tableD.id) on tableC.tableA_id = tableA.id I'd like to use the CakePHP model->find(). This will let me use the Paginator too, since that will not work with custom SQL queries as far as I understand (unless you hardcode one single pagination query to the model which seems a little inflexible to me). What I've tried so far: /* inside tableA_controller.php, inside an action, e.g. "view" */ $this->paginate['recursive'] = -1; # suppress model associations for now $this->paginate['joins'] = array( array( 'table' => 'tableB', 'alias' => 'TableB', 'type' => 'inner', 'conditions' => 'TableB.tableA_id = TableA.id', ), array( 'table' => 'tableC', 'alias' => 'TableC', 'type' => 'left', 'conditions' => 'TableC.tableA_id = TableA.id', 'joins' = array( # this would be the obvious way to do it, but doesn't work array( 'table' => 'tableD', 'alias' => 'TableD', 'type' => 'inner', 'conditions' => 'TableC.tableD_id = TableD.id' ) ) ) ) That is, nesting the joins into the structure. But that doesn't work (CakePHP just ignores the nested 'joins' element which was kind of what I expected, but sad. I have seen hints in comments on how to do subqueries (in the where clause) using a statement builder. Can a similar trick be used here?

  • sqlalchemy relation through another (declarative)

    - by clayg
    Is anyone familiar with ActiveRecord's "has_many :through" relations for models? I'm not really a Rails guy, but that's basically what I'm trying to do. As a contrived example consider Projects, Programmers, and Assignments: from sqlalchemy import create_engine from sqlalchemy.orm import sessionmaker from sqlalchemy import Column, ForeignKey from sqlalchemy.types import Integer, String, Text from sqlalchemy.orm import relation from sqlalchemy.ext.declarative import declarative_base Base = declarative_base() class Assignment(Base): __tablename__ = 'assignment' id = Column(Integer, primary_key=True) description = Column(Text) programmer_id = Column(Integer, ForeignKey('programmer.id')) project_id = Column(Integer, ForeignKey('project.id')) def __init__(self, description=description): self.description = description def __repr__(self): return '<Assignment("%s")>' % self.description class Programmer(Base): __tablename__ = 'programmer' id = Column(Integer, primary_key=True) name = Column(String(64)) assignments = relation("Assignment", backref='programmer') def __init__(self, name=name): self.name = name def __repr__(self): return '<Programmer("%s")>' % self.name class Project(Base): __tablename__ = 'project' id = Column(Integer, primary_key=True) name = Column(String(64)) description = Column(Text) assignments = relation("Assignment", backref='project') def __init__(self, name=name, description=description): self.name = name self.description = description def __repr__(self): return '<Project("%s", "%s...")>' % (self.name, self.description[:10]) engine = create_engine('sqlite://') Base.metadata.create_all(engine) Session = sessionmaker(bind=engine) session = Session() Projects have many Assignments. Programmers have many Assignments. (understatement?) But in my office at least, Programmers also have many Projects - I'd like this relationship to be inferred through the Assignments assigned to the Programmer. I'd like the Programmer model to have a attribute "projects" which will return a list of Projects associated to the Programmer through the Assignment model. me = session.query(Programmer).filter_by(name='clay').one() projects = session.query(Project).\ join(Project.assignments).\ join(Assignment.programmer).\ filter(Programmer.id==me.id).all() How can I describe this relationship clearly and simply using the sqlalchemy declarative syntax? Thanks!

  • Applying for .net jobs as a "self learner"

    - by DeanMc
    Hi All, I have recently started applying for .Net jobs. I currently work in a sales role with a large telco. I found out quite late that I like programming and as such bought my house and made commitments that mean college is not an option. What I would like to know is, is it harder to get a junior job as a self learner? I have gotten a few enquiries regarding my C.V but nothing concrete yet. I try to be involved in projects as I get the chance and tend to put up any worthwhile projects as I develop them. Some examples of my work are: A Xaml lexer and parser: http://www.xlight.mendhak.com A font obfuscation tool: http://www.silverlightforums.com/showthread.php?1516-Font-Obsfucation-Tool-ALPHA A tagger for m4a: http://projectaudiophile.codeplex.com/SourceControl/list/changesets I, of course think that these are great examples of my work but that is my opinion based on self learning. The other query is how much should I actually know? I've never used linked lists but I know that strings are immutable and I understand what that means. I am only touching on T-SQL but I understand things like how properties function in IL (as two standard methods :) ). I suppose I understand a lot of concepts but specific features need some looking up to implement as I may not know the syntax off the top of my head.

  • Help getting MVVM ViewModel to bind to the View

    - by cw
    Okay guys, I'm new to this model and Silverlight in general. I have the following code (changed object names, so syntax/spelling errors ignore). public class ViewModel { ViewModelSource m_vSource; public ViewModel(IViewModelSource source) { m_vSource= source; m_vSource.ItemArrived += new Action<Item>(m_vSource_ItemArrived); } void m_vSource_ItemArrived(Item obj) { Title = obj.Title; Subitems = obj.items; Description = obj.Description; } public void GetFeed(string serviceUrl) { m_vFeedSource.GetFeed(serviceUrl); } public string Title { get; set; } public IEnumerable<Subitems> Subitems { get; set; } public string Description { get; set; } } Here is the code I have in my page's codebehind. ViewModel m_vViewModel; public MainPage() { InitializeComponent(); m_vViewModel = new ViewModel(new ViewModelSource()); this.Loaded += new RoutedEventHandler(MainPage_Loaded); this.DataContext = m_vViewModel; } void MainPage_Loaded(object sender, RoutedEventArgs e) { m_vViewModel.GetItems("http://www.myserviceurl.com"); } Finally, here is a sample of what my xaml looks like. <!--TitleGrid is the name of the application and page title--> <Grid x:Name="TitleGrid" Grid.Row="0"> <TextBlock Text="My Super Title" x:Name="textBlockPageTitle" Style="{StaticResource PhoneTextPageTitle1Style}"/> <TextBlock Text="{Binding Path=Title}" x:Name="textBlockListTitle" Style="{StaticResource PhoneTextPageTitle2Style}"/> </Grid> I know I'm missing something, but I'm just not knowledgable enough which is why I'm asking you guys :) Is there anything I'm doing wrong here? Thanks!

  • XML: what processing rules apply for values intertwined with tags?

    - by iCE-9
    I've started working on a simple XML pull-parser, and as I've just defuzzed my mind on what's correct syntax in XML with regards to certain characters/sequences, ignorable whitespace and such (thank you, http://www.w3schools.com/xml/xml_elements.asp), I realized that I still don't know squat about what can be sketched up as the following case (which Validome finds well-formed very much; note that I only want to use xml files for data storage, no entities, DTD or Schemas needed): <bookstore> <book id="1"> <author>Kurt Vonnegut Jr.</author> <title>Slapstick</title> </book> We drop a pie here. <book id="2">Who cares anyway? <author>Stephen King</author> <title>The Green Mile</title> </book> And another one here. <book id="3"> <author>Next one</author> <title>This time with its own title</title> </book> </bookstore> "We drop a pie here." and "And another one here." are values of the 'bookstore' element. "Who cares anyway?" is a value related to the second 'book' element. How are these processed, if at all? Will "We drop a pie here." and "Another one here." be concatenated to form one value for the 'bookstore' element, or are they treated separately, stored somewhere, affecting the outcome of the parsing of the element they belong to, or...?

  • how can I solve a problem with andWhere with symfony/doctrine and odbc?

  • Does Internet Explorer 7 have a CSS parsing issue with the "background-image" property?

    - by user312003
    Having CSS layout issues with Internet Explorer 7 (big surprise). Upon using the Developer Tools to inspect the CSS, I discovered that some properties defined in the stylesheet are not appearing in the parsed CSS structure... THEN I saw THIS being shown as the parsed value for the background-image property: background-image : url(/trunk/httpdocs/images/layout/HCBL_Homepage_01.jpg); WIDTH: 1200px; pretty much obliterating the width that was defined property. The actual code in the CSS file for this element: div#header { width: 1200px; height: 100px; margin-left: auto; margin-right: auto; background-image: url('/trunk/httpdocs/images/layout/HCBL_Homepage_01.jpg'); background-repeat: no-repeat; } If anyone could offer any insight, or provide a link describing this problem (and maybe a workaround...) I would be very appreciative. Also, I am only interested in this from a parsing of the stylesheet and CSS syntax perspective. I am not concerned with rendering and display issues at the moment; I simply want to get IE 7 (and I have a feeling IE 6 will have similar issues) to recognize and parse ALL of the CSS properties that have been defined in the stylesheet. Thanks in advance guys!

  • Looking for good PHP editor or IDE with 'IntelliSense'

    - by Andrew
    Hello, I'm looking for suitable PHP Editor or IDE with syntax auto-completion. I've tried trial versions of programs like Zend Studio, PHPDesigner, NetBeans PHP, NuSphere PhpED, and similar -- but none of them fully satisfied me. I quite liked hint window with detailed info about what function does and what it returns. Also I liked the way NetBeans auto-complete code (for example inserts all required parameters in function declaration as "dummy fields" and then you can jump between them using TAB in order to edit them). On the other hand, environment of NetBeans doesn't belong to the nicest. In this regard I prefer PHPDesigner with its sleek and light interface. At this moment I don't use any of the debugging options, since I don't know yet how to use profiller, breakpoints, watches and what not, so at this point my only concern is good autocompletion. For this purpose NetBean would be great choice, but with future in mind I am not sure debugging will be good in NetBeans, especially as I would prefer to use remote Linux server for this. So in short, I'm looking for editor that: Have similar code auto-completion (IntelliSense) like NetBeans Allow you to debug code using remote server (or sets up own debugging server like PHPDesigner does) without need to run Apache and similar on local computer Is preferably easy to use / intuitive interface Any ideas?

  • FindControl in DataList Edit Mode

    - by Doug
    As a new .net/C# web begginner, I always get tripped up when I try to use FindControl. Blam -flat on my face. Here is my current FindControl problem: I have an .aspx page and Form, then ajax updatePanel, inside it there is my DataList (DataList1) that has an EditItemTemplate: that has the following: <EditItemTemplate> <asp:Label ID="thumbnailUploadLabel" runat="server" text="Upload a new thumbnail image:"/><br /> <asp:FileUpload ID="thumbnailImageUpload" runat="server" /> <asp:Button ID="thunbnailImageUploadButton" runat="server" Text="Upload Now" OnClick="thumbnailUpload"/><br /> </EditItemTemplate> In my C# code behind I have the OnClick code for the fileUpload object: protected void thumbnailUpload(object s, EventArgs e) { if (thumbnailImageUpload.HasFile) { //get name of the file & upload string imageName = thumbnailImageUpload.FileName; thumbnailImageUpload.SaveAs(MapPath("../../images/merch_sm/" + imageName)); //let'em know that it worked (or didn't) thumbnailUploadLabel.Text = "Image " + imageName + "has been uploaded."; } else { thumbnailUploadLabel.Text = "Please choose a thumbnail image to upload."; } So of course I'm getting "Object reference not set to an instance of an object" for the FileUpload and the Label. What is the correct syntax to find these controls, before dealing with them in the OnClick event? The only way Ive used FindControl is something like: label thumbnailUploadLabel = DataList1.FindControl("thumbnailUploadLabel") as Label; But of course this is throwing the "Object reference not set to an instance of an object" error. Any help is very much appreciated. (I've also seen the 'recursive' code out there that is supposed to make using FindControl easier. Ha! I'm so green at C# that I don't even know how to incorporate those into my project.) Thanks to all for taking a look at this.

  • Dimension Mismatch MatLab; cant figure out why it is mismatching

    - by Abid
    I think it may be a syntax issue, here is the code. load ([ 'C:\Users\Abid\Desktop\Inquiry Runs\dtS' ]) dtS((dtS==0))=nan; for j=2:9; maxS=max(dtS(j,:)); minS=min(dtS(j,:)); maxval(j,:)=dtS((dtS>(maxS-.1*maxS))); minval(j,:)=dtS((dtS<(minS+.1*minS))); avmax(j)=mean(maxval(j,:)); avmin(j)=mean(minval(j,:)); avs(j,:)=[avmax(j) avmin(j)] end So I know the the row matrices are different sizes every loop. For example maxval(j,:) will change depending one row it is looking through for certain values. I did this manually and I see that on the first loop the matrices are size (1,1), however, if I set the loop to run for only j=2, the row length is 13. Usually if a matrix is changing size on the loop, I only get a warning, but this time I think it is due to a reason I don't understand.

  • Beyond core java

    - by Paul
    Coming to the end of the first year of my CS degree, we've done some Java but just the core stuff; manipulating strings and arrays, inheritance, implementing logic etc. I visit this website daily and I see so much stuff that is beyond me; using frameworks; managing databases etc. It makes me feel like I've just learned the syntax of Java, and there is so much more to do with it. My question is though, how do I get there? I don't think I'm advanced enough to join an open source project, which seems to be suggested often (though I'd love to) and I've looked at other similar questions on here (like this one) but even then I don't think that'd work for me.. firstly, could somebody try give me some commonly used frameworks etc and how and what they are used for? Where would be a good place to start? How did you get started in using the things you do? Or perhaps you think I'm going down the wrong route. Should I learn another language, and just wait until the moment occurs where it's clear what I should be doing? I'm only in the first year of my degree, so far we've lightly covered Haskell and Java, and I've done a little HTML and CSS in my free time. I know that next year we cover python, so perhaps I should just wait till then and see if I prefer that? I feel like I also risk learning something in depth and then never using it... I suppose I'm also asking for personal experiences; was there a point where you felt you'd exceeded the basic grasp of a language (does not necessarily have to be Java related) and reach a more "advanced" level? I guess I'll put subjective tag on this, but really I just want to know how to get beyond the basic understanding of a language.

    I am familiar (as a self-learner) with C, python and php such that i can solve some problems involving simple steps (for example, i easily do calculations for physics lab reports with python which normally would take 4x-5x times longer with a calculator). The point here is, as doing such things, i learnt the idea / concepts of programming language and problem solving along with oop or fuctional programming etc. Recently i have started Java and, with the familiarity of other languages, i am doing well for starters but i need guidence. -I am thinking of learning syntax from sun java tutorials and then practicing with codingbat.com or similar sites. I need a reference book that i can study deeper aspects of the topics i am learning. What do you suggest about these? -The problem is (and always have been) the lack of practice. I need coding and problem-solving practices sources. I stuck at the point where i can't figure out what to do next. Can you suggest any source (possibly like codingbat)? If i could plan a learning trail, i can progress faster and efficiently. So i need ideas, comments, suggestions. Thanks in advance.

  • Flex build error

    - by incrediman
    I'm totally new to flex. I'm getting a build error when using flex. That is, I've generated a .c file using flex, and, when running it, am getting this error: 1>lextest.obj : error LNK2001: unresolved external symbol "int __cdecl isatty(int)" (?isatty@@YAHH@Z) 1>C:\...\lextest.exe : fatal error LNK1120: 1 unresolved externals here is the lex file I'm using (grabbed from here): /*** Definition section ***/ %{ /* C code to be copied verbatim */ #include <stdio.h> %} /* This tells flex to read only one input file */ %option noyywrap %% /*** Rules section ***/ /* [0-9]+ matches a string of one or more digits */ [0-9]+ { /* yytext is a string containing the matched text. */ printf("Saw an integer: %s\n", yytext); } . { /* Ignore all other characters. */ } %% /*** C Code section ***/ int main(void) { /* Call the lexer, then quit. */ yylex(); return 0; } As well, why do I have to put a 'main' function in the lex syntax code? What I'd like is to be able to call yylex(); from another c file.

  • jquery - problem with executing annimation of two separate objects, one after another

    - by MoreThanChaos
    Hello I have problem to put together animations of two separate objects to second one start when first one ends. I tried to use callback but it seems that i make some syntax misteakes which crash jQuery or cause some unexpected behaviour. It seems that i'm stuck so I'd like to ask You for best way to put these animations together to act the way I want. in mouseenter 1st .pp grows, 2nd .tt fade in in mouseleave 1st .tt fade out, 2nd .pp shrink It's alsp relevant that animations doesn't pile up, i mean here animation called by one event doesnt wait until other animation in progress will end. In generall exactly what is below but yo be animated one after another, not simultanously. $('.pp').bind({ mouseenter: function() { $(this).animate({ width: $(this).children(".tt").outerWidth(), height: $(this).children(".tt").outerHeight() },{duration:1000,queue:false} ); $(this).children(".tt").animate({ opacity: 1.0 }, {duration:1000,queue:false}); }, mouseleave: function() { $(this).children(".tt").animate({ opacity: 0 }, {duration:1000,queue:false}); $(this).animate({ width: 17, height: 17 }, {duration:1000,queue:false}); } });

  • Creating a form dynamically

    - by Nathan
    Hi, I use a search button that creates a form dynamically at the server side and returns it with Jquery syntax. After I fill-up the form and click on submit button, there is another .submit() Jquery function that suppose to be called to validate input before data is sent to the server. But, for some reason, this function is never called, and the data is request is sent. In more details: This is the form that the serach button creates dynamically at the server side and "prints" to html page with Jquery: <form action=... name="stockbuyform" class="stockbuyform" method="post"> <input type=text value="Insert purchasing amount"> <input type="submit" value="Click to purchase"> </form> And here is the .submit() function : $(".stockbuyform").submit(function() { alert("Need to validate purchasing details"); } But whaen I click on purchase button, the .submit() function is never called. Does it mean that I can't use another Jquery call with the answer I got in the first call?

  • How would you go about parsing markdown?

    - by John Leidegren
    You can find the syntax here. The thing is, the source that follows with the download is written in perl. Which I have no intentions of honoring. It is riddled with regex and it relies on MD5 hashes to escape certain characters. Something is just wrong about that! I'm about to hard code a parser for markdown and I'm wonder if someone had some experience with this? Edit: If you don't have anything meaningful to say about the actual parsing of markdown, spare me the time. (This might sound harsh, but yes, I'm looking for insight, not a solution i.e. third-party library). To help a bit with the answers, regex are meant to identify patterns! NOT to parse an entire grammar. That people consider doing so is foobar. If you think about markdown, it's fundamentally based around the concept of paragraphs. As such, a reasonable approach might be to split the input into paragraphs. There are many kinds of paragraphs e.g. heading, text, list, blockquote, code. The challenge is thus to identify these paragraphs and in what context they occur. I'll be back with a solution, once I find it's worthy to be shared.
