• What is a good way to render a site or portions of a site into a desktop gadget/widget?

  - by Daddy Warbox

  I guess a better way to ask this question (or an alternative to it, in my case) would be to first ask how to do this instead. Namely, I want to have a gadget on my desktop (not just in a browser window) with options such as overlaying on top of other windows, offline caching, etc. that is dedicated expressly to a given website (no browsing functions or menus). Be even more awesome if I could indicate a specific physical part of the website to show in the gadget.

• Java regex replace multiple file paths in a large String

  - by Joe Goble

  So a Regex pro I am not, and I'm looking for a good way to do this. I have a large string which contains a variable number <img> tags. I need to change the path on all of these images to images/. The large string also contains other stuff not just these img's. <img src='http://server.com/stuff1/img1.jpg' /> <img src='http://server.com/stuff2/img2.png' /> Replacing the server name with a ReplaceAll() I could do, it's the variable path in the middle I'm clueless on how to include. It doesn't necessarily need to be a regex, but looping through the entire string just seems wasteful.

• C# socket blocking behavior

  - by Gearoid Murphy

  My situation is this : I have a C# tcp socket through which I receive structured messages consisting of a 3 byte header and a variable size payload. The tcp data is routed through a network of tunnels and is occasionally susceptible to fragmentation. The solution to this is to perform a blocking read of 3 bytes for the header and a blocking read of N bytes for the variable size payload (the value of N is in the header). The problem I'm experiencing is that occasionally, the blocking receive operation returns a partial packet. That is, it reads a volume of bytes less than the number I explicitly set in the receive call. After some debugging, it appears that the number of bytes it returns is equal to the number of bytes in the Available property of the socket before the receive op. This behavior is contrary to my expectation. If the socket is blocking and I explicitly set the number of bytes to receive, shouldn't the socket block until it recv's those bytes?, any help, pointers, etc would be much appreciated.

• Intentionally get a "MySQL server has gone away" error

  - by Jonathan

  I'm trying to cope with MySQL's error MySQL server has gone away in a django env. The quick workaround was to set the global wait_timeout MySQL variable to a huge value, but in the long run this would accumulate to many open connections. I figured I'll get the wait_timeout variable and poll the server in smaller intervals. After implementing this I tried to test it but am failing to get the error. I set global wait_timeout=15 and even set global interactive_timeout=15 but the connection refuses to disappear. I'm sure I'm polling the database in larger intervals than 15sec. What could be the cause for not being able to recreate this error?

• Ruby on Rails - Send JavaScript to view

  - by Eef

  Hey, I am creating a website in Ruby on Rails. I have a controller action that renders a view like so: def show time_left = Time.now.to_i - 3.hours.to_i @character = current_user.characters.find(params[:id]) respond_to do |format| format.html # show.html.erb format.xml { render :xml => @character } end end This is fine as it renders the show.html.erb as I like. I would like however to somehow pass time_left to the view as a Javascript variable as this value is use by a countdown JQuery plugin. I could put a javascript block on the page in the HTML and print a instance variable out like so: <script type="javascript"> $('#countdown').countdown('<%= @time_left =>')</script> But I would like to keep all my JS in a external file and off the page could anyone give some advice on how to implement this? Cheers Eef

• Identify the checkbox that is checked

  - by lucky

  Hello Everyone, I have 2 checkboxes in a form and onclick of these, some php code needs to be executed and based on the result of the code, the checkbox is checked or unchecked. So i have written onclick = document.formName.submit(); Now it is triggering the same page and i am able to write the code. I am not able to differentiate which checkbox is checked. I don't want to use the procedure of:- calling javascript and then storing the value of the checkbox in a variable and making this variable as invisible. I would like to write something like document.formName.submit('checkbox1'). So that i should be able to handle the value of this or i dont know. Please suggest me an alternative method or better approach.

• How to name variables wich are structs

  - by evilpie

  Hello, i often work on private projects using the WinApi, and as you might know, it has thousands of named and typedefed structs like MEMORY_BASIC_INFORMATION. I will stick to this one in my question, what still is preferred, or better when you want to name a variable of this type. Is there some kind of style guide for this case? For example if i need that variable for the VirtualQueryEx function. Some ideas: MEMORY_BASIC_INFORMATION memoryBasicInformation; MEMORY_BASIC_INFORMATION memory_basic_information; Just use the name of the struct non captialized and with or without the underlines. MEMORY_BASIC_INFORMATION basicInformation; MEMORY_BASIC_INFORMATION information; Short form? MEMORY_BASIC_INFORMATION mbi; I often see this style, using the abbreviation of the struct name. MEMORY_BASIC_INFORMATION buffer; VirtualQueryEx defines the third parameter lpBuffer (where you pass the pointer to the struct), so using this name might be an idea, too. Cheers

It does not auto play even the auto play variable is set to true in the RewriteRule. Is there something wrong with my code or it can't be done in swf file?

• Workflow Foundation: How to create Recieve activity with custom message in xaml designer?

  - by Petr Felzmann

  I need to have Recieve activity which can receive my custom data. I found examples, but all use coded workflows like such public class ProcessRequest : Activity { public ProcessRequest() { Variable<MyData> request = new Variable<MyData> { Name = "request" }; Receive receiveRequest = new Receive { ServiceContractName = "IProcessRequest", OperationName = "Foo", CanCreateInstance = true, Content = ReceiveContent.Create(new OutArgument<MyData>(request)) }; } } The main point is that Recieve.Content property. It is not clear for me how I can do it in XAML designer. What I have to set in the dialog of the Content property - Message or Parameters and what to set inside those options? Thanks for the light!

• Python: Find X to Y in a list of strings.

  - by TheLizardKing

  I have a list of maybe a 100 or so elements that is actually an email with each line as an element. The list is slightly variable because lines that have a \n in them are put in a separate element so I can't simply slice using fixed values. I essentially need a variable start and stop phrase (needs to be a partial search as well because one of my start phrases might actually be Total Cost: $13.43 so I would just use Total Cost:.) Same thing with the end phrase. I also do not wish to include the start/stop phrases in the returned list. In summary: email = ['apples','bananas','cats','dogs','elephants','fish','gee'] start = 'ban' stop = 'ele' the magic here new_email = ['cats','dogs'] NOTES While not perfect formatting of the email, it is fairly consistent so there is a slim chance a start/stop phrase will occur more than once. There are also no blank elements.

• WCF REST Does Not Contain All of the Relative File Path

  - by Brandon

  I have a RESTful WCF 3.5 endpoint as such: System.Security.User.svc This is supposed to represent the namespace of the User class and is desired behavior by our client. I have another endpoint I created for testing called: Echo.svc I am writing an overridden IHttpModule and in my module, I follow what almost everyone does by doing: string path = HttpContext.Current.Request.AppRelativeCurrentExecutionFilePath; If I make a call to: http://localhost/services/Echo/test My path variable has a value of '~/echo/test' However, when I make a call to: http://localhost/services/System.Security.User/test My path variable has a value of '~/system.security.user' In my 2nd situation, it is stripping off the '/test' on the end of any endpoint that contains multiple periods. This is undesired behavior and the only solution I have found to fixing this is some ugly string manipulation using the property which does contain the complete URL path: string rawPath = HttpContext.Current.Request.RawUrl; This returns '/services/system.security.user/test'. Does anyone know why my first situation does not return the rest of the URL path for endpoints that contain multiple periods in the name?

• Javascript function as a parameter to another function?

  - by Alex

  Hello there, I'm learning lots of javascript these days, and one of the things I'm not quite understanding is passing functions as parameters to other functions. I get the concept of doing such things, but I myself can't come up with any situations where this would be ideal? My question is: When do you want to have your javascript functions take another function as a parameter? Why not just assign a variable to that functions return value and pass that variable to the function like so: // Why not do this var foo = doStuff(params); callerFunction(foo); //instead of this callerFunction(doStuff); I'm confused as to why I would ever choose to do things as in my second example. Why would you do this? What are the use cases? Thanks!!

• JQuery Syntax Problem?

  - by Michael Smith

  I am using JQuery to insert divs into a page but i cant seem to get the quotation marks correctly setup. For example the code below works fine: var newDiv_1 = '<div id="event_1"><b>Hello World 01</b></div>'; $('#mon_Events').append(newDiv_1); But when i try to use variable in place of the normal text, i doesnt seem to work: var eventname = 1; var newDiv_1 = '<div id="event_' . eventName . '"><b>Hello World 01</b></div>'; $('#mon_Events').append(newDiv_1); How do i use variable inside this statement?

• Javascript: Passing large objects or strings between function considered a bad practice

  - by Mr. Smee

  Is it considered a bad practice to pass around a large string or object (lets say from an ajax response) between functions? Would it be beneficial in any way save the response in a variable and keep reusing that variable? So in the code it would be something like this: var response; $.post(url, function(resp){ response = resp; }) function doSomething() { // do something with the response here } vs $.post(url, function(resp){ doSomething(resp); }) function doSomething(resp) { // do something with the resp here } Assume resp is a large object or string and it can be passed around between multiple functions.

• How do partialviews work in asp.net MVC when passing parameters back?

  - by Rob Ellis

  I have a page with a partialview on it which is a list of items. I have a button on it which shows the next 5 items. This is done via ajax:- using (Ajax.BeginForm("ShowUpdates", new AjaxOptions() { UpdateTargetId = "statusUpdateContainer", InsertionMode = InsertionMode.InsertAfter })) { <input type="submit" class="formbutton" value="Show More" style="width:100%;"/> } My partial view controller: [HttpPost] public ActionResult ShowUpdates(string page, string pagesize) { //get data code hidden here return PartialView("_statusUpdates"); } My question is that I need the 'page' variable to increment each time someone presses the form button which is contained within the partialview. How do I keep track of that variable?

• Wordpress pages address rewrite

  - by kemp

  UPDATE I tried using the internal wordpress rewrite. What I have to do is an address like this: http://example.com/galleria/artist-name sent to the gallery.php page with a variable containing the artist-name. I used these rules as per Wordpress' documentation: // REWRITE RULES (per gallery) {{{ add_filter('rewrite_rules_array','wp_insertMyRewriteRules'); add_filter('query_vars','wp_insertMyRewriteQueryVars'); add_filter('init','flushRules'); // Remember to flush_rules() when adding rules function flushRules(){ global $wp_rewrite; $wp_rewrite->flush_rules(); } // Adding a new rule function wp_insertMyRewriteRules($rules) { $newrules = array(); $newrules['(galleria)/(.*)$'] = 'index.php?pagename=gallery&galleryname=$matches[2]'; return $newrules + $rules; } // Adding the id var so that WP recognizes it function wp_insertMyRewriteQueryVars($vars) { array_push($vars, 'galleryname'); return $vars; } what's weird now is that on my local wordpress test install, that works fine: the gallery page is called and the galleryname variable is passed. On the real site, on the other hand, the initial URL is accepted (as in it doesn't go into a 404) BUT it changes to http://example.com/gallery (I mean it actually changes in the browser's address bar) and the variable is not defined in gallery.php. Any idea what could possibly cause this different behavior? Alternatively, any other way I couldn't think of which could achieve the same effect described in the first three lines is perfectly fine. Old question What I need to do is rewriting this address: (1) http://localhost/wordpress/fake/text-value to (2) http://localhost/wordpress/gallery?somevar=text-value Notes: the remapping must be transparent: the user always has to see address (1) gallery is a permalink to a wordpress page, not a real address I basically need to rewrite the address first (to modify it) and then feed it back to mod rewrite again (to let wordpress parse it its own way). Problems if I simply do RewriteRule ^fake$ http://localhost/wordpress/gallery [L] it works but the address in the browser changes, which is no good, if I do RewriteRule ^fake$ /wordpress/gallery [L] I get a 404. I tried different flags instead of [L] but to no avail. How can I get this to work? EDIT: full .htaccess # BEGIN WordPress <IfModule mod_rewrite.c> RewriteEngine On RewriteRule ^fake$ /wordpress/gallery [R] RewriteBase /wordpress/ RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /wordpress/index.php [L] </IfModule> # END WordPress

• Draw and move a point over an image in python

  - by frx08

  Hi all I have to do a little script in Python. In this script I have a variable (that represents a coordinate) that is continuously updated to a new value. So I have to draw a red point over a image and update the point position every time the variable that contains the coordinate is updated. I tried to explain what I need doing something like this but obviously it doesn't works: import Tkinter, Image, ImageDraw, ImageTk i=0 root = Tkinter.Tk() im = Image.open("img.jpg") root.geometry("%dx%d" % (im.size[0], im.size[1])) while True: draw = ImageDraw.Draw(im) draw.ellipse((i, 0, 10, 10), fill=(255, 0, 0)) pi = ImageTk.PhotoImage(im) label = Tkinter.Label(root, image=pi) label.place(x=0, y=0, width=im.size[0], height=im.size[1]) i+=1 del draw someone may help me please? thanks very much!

• How are variables bound to the body of a define_method?

  - by Chris

  While trying to brush up my Ruby skills I keep running across this case which I can't figure out an explanation for by just reading the API docs. An explanation would be greatly appreciated. Here's the example code: for name in [ :new, :create, :destroy ] define_method("test_#{name}") do puts name end end What I want/expect to happen is that the name variable will be bound to the block given to define_method and that when #test_new is called it will output "new". Instead each defined method outputs "destroy" -- the last value assigned to the name variable. What am I misunderstanding about define_method and its blocks? Thanks!

• JDBC CLASSPATH Not Working

  - by AeroDroid

  I'm setting up a simple JDBC connection to my working MySQL database on my server. I'm using the Connector-J provided by MySQL. According to their documentation, I'm suppose to create the CLASSPATH variable to point to the directory where the mysql-connector-java-5.0.8-bin.jar is located. I used export set CLASSPATH=/path/mysql-connector-java-5.0.8-bin.jar:$CLASSPATH. When I type echo $CLASSPATH to see if it exists, everything seems fine. But then when I open a new terminal and type echo $CLASSPATH it's no longer there. I think this is the main reason why my Java server won't connect to the JDBC, because it isn't saving the CLASSPATH variable I set. Anyone got suggestions or fixes on how to set up JDBC in the first place?

• How to generate unique number of 12 digits?

  - by DanSogaard

  I'm working on an app that sends raw data to zebra printer and print out barcodes. And since every item has its own unique barcode, I need to define a variable that automatically generates unique number of 12 digits long. see example: printBar prnt = new printBar("123456789012"); Is there anyway to define a double variable and pass it to a function that return uniqely 12 digits number and pass it over again to the printBar class?. But how to make sure everytime you access it returns a unique value?. I also thought of another way, since am using MS Access db, I can create a column of AutoNumber datatype and assign it to Random, but you don't get the exact 12 digits required, sometimes it generates a value of 10 digits sometimes more or less.

• Actionscript 2.0 Functions problem

  - by Joshua

  I have two problems. The first problem is with the following functions; when I call the function in (enterFrame), it doesn't work: onClipEvent (load) { function failwhale(levelNum) { _root.gotoAndStop("fail"); failFrom = levelNum; } function guardSightCollision(guardName, guardSightName) { if (_root.guardName.guardSightName.hitTest(_x, _y+radius, true)) { failwhale(1); } if (_root.guardName.guardSightName.hitTest(_x, _y-radius, true)) { failwhale(1); } if (_root.guardName.guardSightName.hitTest(_x-radius, _y, true)) { failwhale(1); } if (_root.guardName.guardSightName.hitTest(_x+radius, _y, true)) { failwhale(1); } } } onClipEvent (enterFrame) { guardSightCollision(guard1, guard1Sight); } Why doesn't it work?... The second problem lies in the failFrom variable: function failwhale(levelNum) { _root.gotoAndStop("fail"); failFrom = levelNum; } How do I make failFrom a "global" variable in that it can be accessed anywhere (from actionscript in frames and even movieclips)...Right now, when I try to trace failFrom in a different frame, it is "undefined".

• How can I extract and save values from an XML file in Perl?

  - by Freddy

  Here is what I am trying to do in a Perl script: $data=""; sub loadXMLConfig() { $filename="somexml.xml" $data = $xml-XMLin($filename); } sub GetVariable() { ($FriendlyName) = @_; switch($FriendlyName) { case "My Friendly Name" {print $data-{my_xml_tag_name}} .... .... .... } } The problem is I am using Perl just because I am reading from an XML file, but I need to get these variables by a shell script. So, here is what I am using: $ perl -e 'require "scrpt.pl"; loadConfigFile(); GetVariable("My Variable")' This works exactly as expected, but I need to read the XML file every time I am getting a variable. Is there a way I could "preserve" $data across shell calls? The idea is that I read the XML file only once. If no, is there is a more simple way I could do this? These are the things I can't change: Config File is an XML Need the variables in a shell script

• Passing variables to functions in Python

  - by brno792

  Im writing test scripts in python for selenium web testing. How do I pass parameters through a python function to call in a later function? I first have a login test function. Then I have a new user registration function. Im trying to pass the Username and Password I use in the registration function to the testLogin function that I call inside the testRegister function. This is my python code: userName = "admin" password = "admin" #pass username and password variables to this function def testLogin(userName,password): browser = webdriver.Firefox() browser.get("http://url/login") element = browser.find_element_by_name("userName") element.send_keys(userName) element = browser.find_element_by_name("userPassword") element.send_keys(password) element.send_keys(Keys.RETURN) browser.close() # test registration def testRegister(): browser = webdriver.Firefox() browser.get("http://url/register") #new username variable newUserName = "test" element = browser.find_element_by_name("regUser") element.send_keys(newUserName) #new password variable newUserPassword = "test" element = browser.find_element_by_name("regPassword") element.send_keys(newUserPassword) # #now test if user is registered, I want to call testLogin with the test user name and pw. testLogin(newUserName,newUserPassword) browser.close()

• Add the "selected" attribute to a drop down option with jQuery

  - by gaoshan88

  How do I add the attribute "selected" to a drop down menu option based on that option matching some variable? Here is how the dropdown is populated... loginOptions = ["First", "Second", "Third]; var Login = $( '#Login' ); for ( var i = 0; i < loginOptions.length; i++ ) { Login.append('<option value="'+ loginOptions[i] +'">'+ loginOptions[i] +'</option>'); } I want to mark one option as "selected" based on whether or not its value matches another variable. so if loginOption[i] is equal to var existingLoginValue then set that option to 'selected' Something that would do if(loginOptions[i] === existingLoginValue){ print 'selected'; }; Thanks!
