  • Getting ready to learn html5

    - by vtortola
    I'm a desktop application developer, and I plan learning html5, but as it's not released, there are (almost) no published books and not too much infomation for beginners on the web... I feel I should start with html4 and the current web development skills. I think I should start with html4, css, and javascript... but there are so many technologies related that I get lost :D So, what current technologies will be still used when html5 is released? I mean, what about "jquery" and "ajax"? I know they are javascript under the hood, but will they still make sense in the future? What would you recommend me considering that I have just a little bit of html knowlegde, almost null CSS and completely null in javascript?

  • Can I use XText for a DSL involving an XML file type?

    - by Chris
    I have defined a small DSL that is mostly written in the form of different types of XML files in conjuction with some property files. This works very well but I wish to create an Eclipse Editor to make editing these files easier for beginners (I already have a working parser). The main XML file can reference some items from the .properties files and vice-versa. THe main xml file can also reference other XML files. Certain options should only be available in the main xml file based on the contents of the .properties files and based on some osgi plugins that can be added to the DSL project (the syntax is dynamic depending on context). The structure of the language is fixed but the options available in each attribute or the choice of attributes themselves changes depending on metadata contained in plugin .jar files. Questions: Does XText support dynamic syntax (validation changes depending on external factors)? Does XText support XML files / .properties files? Thank you very much for your help in advance.

  • Parse error: syntax error, unexpected T_PUBLIC in ..... ?

    - by tonsils
    Hi, I am new to php and trying out this tutorial at : http://css-tricks.com/php-for-beginners-building-your-first-simple-cms/ Unfortunately I am getting the following error and can't seem to track down the reason: Parse error: syntax error, unexpected T_PUBLIC in ../simpleCMS.php on line 56 My code for simpleCMS.php is as is in the tutorial link above. FYI, my line 56 is the following line of code in simpleCMS.php public function display_admin() { Above this line is public function display_public() Can anyone possibly see what I could be doing wrong and again, my code is the same code from the tutorial website and have downloaded the files that came with it? Hoping someone can point me in the right direction. Furthermore, I am using Mac OS X MAMP to run my Apache/MySQL Server locally. My other question is, when I using the following command: mysql_connect($this->host,$this->username,$this->password) is my hostname 'localhost' alone or do I also have to include port alongside the localhost? Thanks again.

  • Android/Java Beginner: Overriding ArrayAdapter's getView

    - by Preformed Cone
    Firstly I am new to android and Java so this is a beginners question. I have some code that overrides the ArrayAdapter's getView method. Here is the code public View getView(int position, View convertView, ViewGroup parent) { TextView label = (TextView)convertView; if (convertView == null) { convertView = new TextView(ctxt); label = (TextView)convertView; } label.setText(items[position]); return (convertView); } My question is: why does label.setText(items[position]); affect the convertView return value? How are they related / linked?

  • decompress .gz file in batch

    - by kapildalwani
    I have 100 of .gz files which I need to de-compress. I have couple of questions a) I am using the code given at http://www.roseindia.net/java/beginners/JavaUncompress.shtml to decompress the .gz file. Its working fine. Quest:- is there a way to get the file name of the zipped file. I know that Zip class of Java gives of enumeration of entery file to work upon. This can give me the filename, size etc stored in .zip file. But, do we have the same for .gz files or does the file name is same as filename.gz with .gz removed. b) is there another elegant way to decompress .gz file by calling the utility function in the java code. Like calling 7-zip application from your java class. Then, I don't have to worry about input/output stream. Thanks in advance. Kapil

  • Print ms access data in vb.net

    - by user225269
    How do I print the ms access data(.mdb) in vb.net? Here is the code that I'm using to view the data in the form. What I want to do is to be able to print what is currently being viewed. Perhaps automatically save the .pdf file and the pdf viewer installed on the system will open that newly generated pdf file Dim cn As New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\search.mdb") Dim cmd As OleDbCommand = New OleDbCommand("Select * from GH where NAME= '" & TextBox6.Text & "' ", cn) cn.Open() Dim rdr As OleDbDataReader rdr = cmd.ExecuteReader If rdr.HasRows Then rdr.Read() NoAcc = rdr("NAME") If (TextBox6.Text = NoAcc) Then TextBox1.Text = rdr("IDNUMBER") If (TextBox6.Text = NoAcc) Then TextBox7.Text = rdr("DEPARTMENT") If (TextBox6.Text = NoAcc) Then TextBox8.Text = rdr("COURSE") End If -some sites for beginners regarding this topic would help a lot:)

  • Nginx rewrite for link shortener and Wordpress

    - by detusueno
    I'm a complete newbie to Nginx, so much so that I followed a online guide to do most of my server setup. I'm trying to learn but I'm still a ways away from understanding it all. So what I'm trying to create is a link shortener that redirects (example.com/x) to (example.com/short.php?id=x). Keep in mind that I'm also running a Wordpress blog on the same domain and plan on using the redirects/shortening for external links. The guide has so far had me add the following rewrites to enable Wordpress pretty URLs: # WordPress pretty URLs: (as per dominiek.com) if (-f $request_filename) { break; } if (-d $request_filename) { break; } rewrite ^(.+)$ /index.php?q=$1 last; # Enable nice permalinks for WordPress: (as per Yawn.it) error_page 404 = //index.php?q=$uri; And if it matters any, it was saved at (/usr/local/nginx/conf/wordpress_params.regular). Additionally, my Wordpress link structure adds "news" to all internal links (example.com/news/post-blah, example.com/news/category, ect.). What's the best way to tackle this setup?

  • Are there any pitfalls to var something = something || {}

    - by puk
    I came across this answer where the poster suggested that the shorthand for if(typeof MyNamespace === 'undefined'){ var MyNamespace = {}; } is var MyNamespace = MyNamespace || {}; Would veteran programmers recommend the latter to simplify the code, or does it overly complicate things, like abusing ++ or -- in complex compound statements? EDIT The reason I asked is b/c a while back someone inspired me by pointing out that a lot of the people who think they are expert programmers make a lot of beginners mistakes. The case at the time was if (isReady){ //Do Something } And what he was saying is that a condition should mean something, isReady doesn't 'mean' anything, instead, we should use if (isReady === true){ //Do Something }

  • Getting started with silverlight 3 mvvm

    - by bplus
    I've just written my first silverlight 3 app. It's written using the code behind in a rater messy way. I want to refactor into mvvm. I'm finding it extremely difficult to find any tutorials on this. So far from what I can gather I'll probably need a mvvm framework. Mvvm-light toolkit sounds like it might be what I want, but I can't find a beginners tutorial. This is actually more frustrating than I thought - do I actually need a framework? Would I maybe be better just trying to do this from scratch with out a framework? How did you get started with silverlight and mvvm? Also I'm using vs2008 so silverlight 4 is a non starter for me. Thanks in advance for any pointers.

  • Objective-C and NSURL: where am I supposed to declare receivedData?

    - by jthomas
    I have a two classes, a controller called "AppController" and a class called "URLDelegate" that encapsulates the sample NSURL code from Apple's URL Loading System Programming Guide. The guide repeatedly mentions declaring the receivedData instance variable "elsewhere." I assume this means outside of the URLDelagate class, because if I declare it in the URLDelegate class, my controller class can't "see" the data that has been downloaded. I know that data is received, because in my connectionDidFinishLoading function, I have NSLog display the results: NSLog(@"Succeeded! Received %d bytes of data",[receivedData length]); receivedText=[[NSString alloc] initWithData:receivedData encoding: NSASCIIStringEncoding]; NSLog(@"receivedText=%@",receivedText); So I'm a bit stumped with the following questions: Where should I declare receivedData? My controller class? A third class? Can I just declare it like any normal NSMutableData variable? How do I give my URLDelegate class "access" to this variable? E.g., if I declare receivedData in my AppController class, wouldn't I have to instantiate AppController within URLDelegate? But how would this possible if it's the AppController class which is instantiating the URLDelegate class in the first place? Especially with regard to the last question, I feel like I must be overlooking something blindingly obvious and fundamental. If anyone could point me in the right direction, I would really appreciate it. Thank you!

  • Compiling gstreamer plugin in windows

    - by utnapistim
    Hello all, My question: What is the correct way to compile a gstreamer plugin in windows, so that it will be accepted by gstreamer (actually Songbird on top of gstreamer). My setup: I have downloaded the songbird sources following the steps described here and I have a trunk/dependencies/windows-i686-msvc8 directory within my svn sources with all the gstreamer binaries. I have created a gstreamer empty plugin skeleton following the steps detailed in the GStreamer Plugin Writer's Guide, and compiled it against the gstreamer binaries in the Songbird dependencies folder. The compilation was done with VS2010 RC1 (Visual Studio 2008 yelded the same results), using an empty DLL project with the .h and .c files generated using the GStreamer Plugin Writer's Guide. The DLL was lined with libcpmt.lib, libcmt.lib, ws2_32.lib, gobject-2.0.lib, gthread-2.0.lib, gstreamer-0.10-0.lib, glib-2.0.lib, kernel32.lib, nspr4.lib and ignoring all default libraries. I have compiled the files as both .c and .cpp with the same results. Testing: I have installed the Songbird binaries corresponding to the correct svn version, then installed Songbird Developer Tools addon and used it to create an addon for testing my gstreamer plugin. Songbird will not load the pluggin. I have also tried to load it with gst-launch.exe from the trunk/dependencies/windows-i686-msvc8/[...] directory and that generated runtime error R6034: An application has made an attempt to load the C runtime library incorrectly. Most resources I found for this problem recommended restarting or reinstalling windows :(.

  • Cannot call scalar-valued CLR UDF from select ... from table statement

    - by Henrik B
    I have created a scalar-valued CLR UDF (user defined function). It takes a timezone id and a datetime and returns the datetime converted to that timezone. I can call it from a simple select without problems: "select dbo.udfConvert('Romance Standard Time', @datetime)" (@datetime is of course a valid datetime variable) But if I call it passing in a datetime from a table it fails: "select dbo.udfConvert('Romance Standard Time', StartTime) from sometable" (column StartTime is of course a column of type datetime) The error message is: "Cannot find either column "dbo" or the user-defined function or aggregate "dbo.udfConvert", or the name is ambiguous." This message is really for beginners that has misspelled something, but as it works in one case and not in the other, I don't think I have done any misspellings. Any ideas?

    - by Ahmad
    'SOUP.IO' is not providing any api. So Iam trying to use 'PHP Curl' to login and submit data through PHP. Iam able to login the website successfully(through cUrl), but when I try to submit data through cUrl, it gives me error of 'invalid user'. When I tried to analysed the code and website, I came to know that cUrl is getting values of only 1-2 cookies.

  • What is the PastryKit Framework?

    - by Kerrick
    I'm trying to find any information I can on the PastryKit Javascript Framework. It appears to be in use on the iPhone User Guide that is displayed on the iPhone itself in Mobile Safari, but I cannot find any documentation or API. If you want to see it in action, open Safari 4, set your user agent to iPhone 3 (In the Develop menu) and check out the guide. Overall, it seems to be a way to write an HTML/CSS/Javascript application that acts like a native iPhone app. When it comes to Javascript, I used the JS Beautifier on (what I assume to be) the framework file and it was over 3,400 lines! Beautified, (again what I assume to be) their implementation of it was over 1,200 lines. On the CSS side, I used Clean CSS on (again what I assume to be) the framework CSS, and it came out to over 700 lines. Their implementation was shy of 500. Does anybody have, or know where to find, any information, documentation, or APIs on PastryKit? Or, can anybody figure out how to implement it?

  • LINQ to SQL or Entities, at this point?

    - by orlon
    I'm a bit late to the game and have decided to spend some spare time learning LINQ. As an exercise, I'm going to rewrite a WebForms app in MVC 2 (which is also new to me). I managed to find a few topics regarding LINQ here (http://stackoverflow.com/questions/16322/learning-about-linq, http://stackoverflow.com/questions/8050/beginners-guide-to-linq, http://stackoverflow.com/questions/252683/is-linq-to-sql-doa), which brought the concern of Entities vs SQL to my attention. The threads are all over a year old however, and I can't seem to find any definitive information on which ORM is preferable. Is Entities more or less LINQ to SQL 2.0 at this point? Is it still more difficult to use? Is there any reason to use LINQ to SQL, or should I just jump into Entities? The applications I write at my present employer have a lengthy lifecycle (~10 years), so I'm trying to pick the best technology available.

  • Target module with custom layout in Magento

    - by dardub
    In my custom module, I'd like to include an extra block and style sheet that targets only pages within my custom module. So that when i access myserver.com/configurator/ Pages will use the correct template I specified In the catalog.xml file, I noticed <catalog_category_default> That seems to be what I am looking for, so I tried: <configurator_default_default> <reference name="root"> <action method="setTemplate"><template>configurator/2columns-right.phtml</template></action> </reference> <reference name="head"> <action method="addCss"><stylesheet>css/configurator.css</stylesheet></action> </reference> <reference name="content"> <block type="configurator/guide" name="timeline" template="configurator/guide/timeline.phtml" /> </reference> </configurator_default_default> But it doesn't change the template for pages within the module. I also tried <configurator_guide_default> But it doesn't pick up the correct template If i put it within the specific page such as <configurator_guide_page1> Then it works.

  • Forcing Flex to update the screen?

    - by ABBarton
    This may be a bit of a beginners question, but I can't for the life of me figure it out. I'm using flex to develop a GUI for a large project, specifically a status bar along the bottom. Within my StatusBar class is a ProgressBar, which other classes doing work can tell to update(change bar completion and label) as they progress. The problem I'm encountering is that flex won't update whats shown on the screen until it's too late, for example ProgressBar initialized, 0% done some class sets the ProgressBar to be 12% done some class does some work some class sets the ProgressBar to be 56% done Whats happening is the 12% done is never displaying, it just hangs at 0% during the work, then skips right to 56% done. I've tried to understand the lifecycle of a flex component (invalidation and validation), and I think I understand it and am applying it correctly, but it's not working at all. I need to tell flex to redraw my StatusBar (or at least the ProgressBar within) after some class sets it to be 12% done, but before some class starts doing its work. How do I do this?

  • Communicating between classes set up in nib, in code?

    - by cannyboy
    A beginner's question: If, in your nib, you have the File's Owner linked to the ViewController class, and you also have a NSObject-derived class, how do you communicate between the ViewController class and the NSObject class within code? For instance, suppose ScientificCalculatorView.xib looks like this File's Owner (class: ScientificCalculatorViewController) FirstResponder View Calculator (an object that has been linked to the Calculator class) Obviously, I'd want Calculator to be reusable, so it could be used with a NormalCalculatorViewController or something like that. So that UI and the calculator code are separate. Does Calculator even need to be in the nib? It's a beginners question, but I'm just trying to get my head around it.

  • .ico icons not showing up on Windows

    - by Ali
    I followed the The Qt Resource System guide and the .ico icons appear on Linux. The icons are not showing up on Windows when I try to run the applicaton from Qt Creator. I suspect a plugin issue based on Qt/C++: Icons not showing up when program is run under windows O.S but I failed to figure out what to do from the guide How to Create Qt Plugins. Is it a plugin issue or why aren't the icons showing up on Windows? If it is a plugin issue: How do I tell my applicaton where to find the qico.dll? Details of the environment: Works on: Kubuntu 12.04 LTS, Qt Creator 2.4.1 and Qt 4.7.4 (64 bit) Fails on: Windows XP SP2 32 bit, Qt Creator 2.4.1 and Qt 4.7.4 (32 bit) Everyting is at its default (as installed out of the box), I did not mess with the settings. resources.qrc <!DOCTYPE RCC><RCC version="1.0"> <qresource> <file>images/spreadsheet.ico</file> </qresource> </RCC> Also tried with <qresource prefix="/">. From the applicaton.pro RESOURCES += \ resources.qrc OTHER_FILES += \ images/spreadsheet.ico In the corresponding source file QIcon(":/images/spreadsheet.ico") I repeat: it works on Linux.

  • Android - Adding external library to project

    - by mmontalbo
    Hi, I am having a lot of trouble adding the WEKA library to a project I am working on. I have followed several tutorials that explain how to do this including the Android Developers guide: http://developer.android.com/guide/appendix/faq/commontasks.html#addexternallibrary and several of the postings on SO. I have created a folder in my project with the weka.jar file, created a new library (adding the weka.jar file to the library) and included this library in my build path. I have also added the library under the "Order and Export" tab in the project properties. I have also tried importing the jar file so that the actual contents of the jar are extracted into a directory in my project. The end result of all of this is that my project is able to build correctly and without error, but when it comes time to run my code on the emulator I get the following exception: 04-10 22:52:21.051: ERROR/dalvikvm(582): Could not find class 'weka.classifiers.trees.J48', referenced from method edu.usc.student.composure.classifier.GaitClassifierImpl. with J48 being the class I reference in my code. Does anyone have any additional suggestions that I may have overlooked? Thanks!
