  • Navbar Menu Trouble shoot

    - by Nabeel M
    So I wanted to create the fixed nav bar on top of the page. Instead of creating nav bar with ordered list, I used the following approach: <header> <div class="nav"> <img src="images/logo_ab.png" alt="AurinBioTech Logo"/> <a href="index.html">Home</a> <a href="#">About</a> <a href="#">Team</a> <a href="#">Science</a> <a href="#">Need</a> <a href="#">Pipeline</a> <a href="#">Contact</a> </div> </header> CSS: header .nav { margin-top:100px; width:100%; height:10%; text-align:center; padding-top:2%; margin:0 auto; position:fixed; top:0; } header .nav a { font-size: 2em; padding-left: 15px; padding-right: 15px; color:rgb(1, 1, 1); text-decoration: none; font-family: 'Bebas'; } header .nav a:hover { color:white; background-color: #404040; border-radius:5px; padding:0 auto; } header .nav a:active{ background-color: #404040; border-radius:5px; text-decoration:overline; } header .nav img { width:260px; height:65px; padding-right:4em; } The reason I used this approach is because I wanted to use logo image next to the nav bar so it would align properly in the same line. Now the problem is that I need to add sub-menus under Science and Pipeline heading. Since I didn't use UL or LI, how can I add sub-menus under those heading. OR, can you tell me any other way to create a NAV bar that shows the logo as well. so it would be LOGO and MENUS on the same line. Great thanks in advance.

  • make img height 100% of td

    - by kristina childs
    I'm creating an HTML email and since background images can't be used on anything but <body> thought I could get around this by making a border image 100% height within a cell. Perhaps it was wishful thinking? I've searched at the solutions that worked in the past no longer work in modern browsers. Is there any special trick to making this happen without setting a hard height for the cell? Here are the things I've tried so far: <td width="25" style="margin:0; padding:0;"> <img src="http://www.mysite.com/images/side-left.jpg" width="25" height="100%" alt="border" style="margin:0; padding:0; display: block;" /> </td> stretches the image to 100% height of the entire table (even though the table is nested in a <td width="25" height="100%" style="margin:0; padding:0;"> <div style="height:100%; diplay: block;"> <img src="http://www.mysite.com/images/side-left.jpg" width="25" height="100%" alt="border" style="margin:0; padding:0; display: block;" /> </div> </td> ditto <td width="25" height="1" style="margin:0; padding:0;"> <div style="height:100%; diplay: block;"> <img src="http://www.mysite.com/images/side-left.jpg" width="25" height="100%" alt="border" style="margin:0; padding:0; display: block;" /> </div> </td> setting a smaller td size does not force it to strectch as expected. bummer.

  • Python: (sampling with replacement): efficient algorithm to extract the set of UNIQUE N-tuples from a set

    - by Homunculus Reticulli
    I have a set of items, from which I want to select DISSIMILAR tuples (more on the definition of dissimilar touples later). The set could contain potentially several thousand items, although typically, it would contain only a few hundreds. I am trying to write a generic algorithm that will allow me to select N items to form an N-tuple, from the original set. The new set of selected N-tuples should be DISSIMILAR. A N-tuple A is said to be DISSIMILAR to another N-tuple B if and only if: Every pair (2-tuple) that occurs in A DOES NOT appear in B Note: For this algorithm, A 2-tuple (pair) is considered SIMILAR/IDENTICAL if it contains the same elements, i.e. (x,y) is considered the same as (y,x). This is a (possible variation on the) classic Urn Problem. A trivial (pseudocode) implementation of this algorithm would be something along the lines of def fetch_unique_tuples(original_set, tuple_size): while True: # randomly select [tuple_size] items from the set to create first set # create a key or hash from the N elements and store in a set # store selected N-tuple in a container if end_condition_met: break I don't think this is the most efficient way of doing this - and though I am no algorithm theorist, I suspect that the time for this algorithm to run is NOT O(n) - in fact, its probably more likely to be O(n!). I am wondering if there is a more efficient way of implementing such an algo, and preferably, reducing the time to O(n). Actually, as Mark Byers pointed out there is a second variable m, which is the size of the number of elements being selected. This (i.e. m) will typically be between 2 and 5. Regarding examples, here would be a typical (albeit shortened) example: original_list = ['CAGG', 'CTTC', 'ACCT', 'TGCA', 'CCTG', 'CAAA', 'TGCC', 'ACTT', 'TAAT', 'CTTG', 'CGGC', 'GGCC', 'TCCT', 'ATCC', 'ACAG', 'TGAA', 'TTTG', 'ACAA', 'TGTC', 'TGGA', 'CTGC', 'GCTC', 'AGGA', 'TGCT', 'GCGC', 'GCGG', 'AAAG', 'GCTG', 'GCCG', 'ACCA', 'CTCC', 'CACG', 'CATA', 'GGGA', 'CGAG', 'CCCC', 'GGTG', 'AAGT', 'CCAC', 'AACA', 'AATA', 'CGAC', 'GGAA', 'TACC', 'AGTT', 'GTGG', 'CGCA', 'GGGG', 'GAGA', 'AGCC', 'ACCG', 'CCAT', 'AGAC', 'GGGT', 'CAGC', 'GATG', 'TTCG'] Select 3-tuples from the original list should produce a list (or set) similar to: [('CAGG', 'CTTC', 'ACCT') ('CAGG', 'TGCA', 'CCTG') ('CAGG', 'CAAA', 'TGCC') ('CAGG', 'ACTT', 'ACCT') ('CAGG', 'CTTG', 'CGGC') .... ('CTTC', 'TGCA', 'CAAA') ] [[Edit]] Actually, in constructing the example output, I have realized that the earlier definition I gave for UNIQUENESS was incorrect. I have updated my definition and have introduced a new metric of DISSIMILARITY instead, as a result of this finding.

  • Why doesen't the number 2 work in this for-loop?

    - by Emil
    Hello. I have a function that runs trough each element in an array. It's hard to explain, so I'll just paste in the code here: NSLog(@"%@", arraySub); for (NSString *string in arrayFav){ int favoriteLoop = [string intValue] + favCount; NSLog(@"%d", favoriteLoop); id arrayFavObject = [array objectAtIndex:favoriteLoop]; [arrayFavObject retain]; [array removeObjectAtIndex:favoriteLoop]; [array insertObject:arrayFavObject atIndex:0]; [arrayFavObject release]; id arraySubFavObject = [arraySub objectAtIndex:favoriteLoop]; [arraySubFavObject retain]; [arraySub removeObjectAtIndex:favoriteLoop]; [arraySub insertObject:arraySubFavObject atIndex:0]; [arraySubFavObject release]; id arrayLengthFavObject = [arrayLength objectAtIndex:favoriteLoop]; [arrayLengthFavObject retain]; [arrayLength removeObjectAtIndex:favoriteLoop]; [arrayLength insertObject:arrayLengthFavObject atIndex:0]; [arrayLengthFavObject release]; } NSLog(@"%@", arraySub); The array arrayFav contains these strings: "3", "8", "2", "10", "40". Array array contains 92 strings with a name. Array arraySub contains numbers 0 to 91, representing a filename with a title from the array array. Array arrayLength contains 92 strings representing the size of each file from array arraySub. Now, the first NSLog shows, as expected, the numbers 0 to 91. The NSLog-s in the loop shows the numbers 3, 8, 2, 10, 40, also as expected. But here's the odd part: the last NSLog shows these numbers: 40, 10, 0, 8, 3, 1, 2, 4, 5, 6, 7, 9, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91 that is 40, 10, 0, 8, 3, and so on. It was not supposed to be a zero in there, it was supposed to be a 2.. Do you have any idea at why this is happening or a way to fix it? Thank you.

  • How to setup Lucene/Solr for a B2B web app?

    - by Bill Paetzke
    Given: 1 database per client (business customer) 5000 clients Clients have between 2 to 2000 users (avg is ~100 users/client) 100k to 10 million records per database Users need to search those records often (it's the best way to navigate their data) Possibly relevant info: Several new clients each week (any time during business hours) Multiple web servers and database servers (users can login via any web server) Let's stay agnostic of language or sql brand, since Lucene (and Solr) have a breadth of support For Example: Joel Spolsky said in Podcast #11 that his hosted web app product, FogBugz On-Demand, uses Lucene. He has thousands of on-demand clients. And each client gets their own database. They use an index per client and store it in the client's database. I'm not sure on the details. And I'm not sure if this is a serious mod to Lucene. The Question: How would you setup Lucene search so that each client can only search within its database? How would you setup the index(es)? Where do you store the index(es)? Would you need to add a filter to all search queries? If a client cancelled, how would you delete their (part of the) index? (this may be trivial--not sure yet) Possible Solutions: Make an index for each client (database) Pro: Search is faster (than one-index-for-all method). Indices are relative to the size of the client's data. Con: I'm not sure what this entails, nor do I know if this is beyond Lucene's scope. Have a single, gigantic index with a database_name field. Always include database_name as a filter. Pro: Not sure. Maybe good for tech support or billing dept to search all databases for info. Con: Search is slower (than index-per-client method). Flawed security if query filter removed. One last thing: I would also accept an answer that uses Solr (the extension of Lucene). Perhaps it's better suited for this problem. Not sure.

  • Loading datasets from datastore and merge into single dictionary. Resource problem.

    - by fredrik
    Hi, I have a productdatabase that contains products, parts and labels for each part based on langcodes. The problem I'm having and haven't got around is a huge amount of resource used to get the different datasets and merging them into a dict to suit my needs. The products in the database are based on a number of parts that is of a certain type (ie. color, size). And each part has a label for each language. I created 4 different models for this. Products, ProductParts, ProductPartTypes and ProductPartLabels. I've narrowed it down to about 10 lines of code that seams to generate the problem. As of currently I have 3 Products, 3 Types, 3 parts for each type, and 2 languages. And the request takes a wooping 5500ms to generate. for product in productData: productDict = {} typeDict = {} productDict['productName'] = product.name cache_key = 'productparts_%s' % (slugify(product.key())) partData = memcache.get(cache_key) if not partData: for type in typeData: typeDict[type.typeId] = { 'default' : '', 'optional' : [] } ## Start of problem lines ## for defaultPart in product.defaultPartsData: for label in labelsForLangCode: if label.key() in defaultPart.partLabelList: typeDict[defaultPart.type.typeId]['default'] = label.partLangLabel for optionalPart in product.optionalPartsData: for label in labelsForLangCode: if label.key() in optionalPart.partLabelList: typeDict[optionalPart.type.typeId]['optional'].append(label.partLangLabel) ## end problem lines ## memcache.add(cache_key, typeDict, 500) partData = memcache.get(cache_key) productDict['parts'] = partData productList.append(productDict) I guess the problem lies in the number of for loops is too many and have to iterate over the same data over and over again. labelForLangCode get all labels from ProductPartLabels that match the current langCode. All parts for a product is stored in a db.ListProperty(db.key). The same goes for all labels for a part. The reason I need the some what complex dict is that I want to display all data for a product with it's default parts and show a selector for the optional one. The defaultPartsData and optionaPartsData are properties in the Product Model that looks like this: @property def defaultPartsData(self): return ProductParts.gql('WHERE __key__ IN :key', key = self.defaultParts) @property def optionalPartsData(self): return ProductParts.gql('WHERE __key__ IN :key', key = self.optionalParts) When the completed dict is in the memcache it works smoothly, but isn't the memcache reset if the application goes in to hibernation? Also I would like to show the page for first time user(memcache empty) with out the enormous delay. Also as I said above, this is only a small amount of parts/product. What will the result be when it's 30 products with 100 parts. Is one solution to create a scheduled task to cache it in the memcache every hour? It this efficient? I know this is alot to take in, but I'm stuck. I've been at this for about 12 hours straight. And can't figure out a solution. ..fredrik

  • Jquery Var Returned As object

    - by alex
    I'm trying to pass a variable from one function to another, but the var elmId is being returned as an object and giving an error. When we click on any of the generated divs we should be able to change the size of the div by choosing a width / height value from the drop down menus. I'm trying to pass the clicked div id which is elmId to function displayVals but it is not working. If we replace "#"+elmId in the function displayVals with the actual id of the first div created with is "#divid1" then it works. Why is the value of var elmId not being passed to displayVals <link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.7/themes/base/jquery-ui.css" type="text/css" media="all" /> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js" type="text/javascript"></script> <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.7/jquery-ui.min.js" type="text/javascript"></script> <style> .aaa{width:100px; height:100px; background-color:#ccc;} button{width:100px; height:20px;} </style> <button class="idiv">div</button> <select id="width"> <option>100px</option> <option>200px</option> <option>300px</option> </select> <select id="height"> <option>100px</option> <option>200px</option> <option>300px</option> </select> <p></p> <script type="text/javascript"> var divId = 1; $("button").click(function(){ var elm = $('<div id=divid' + divId + ' class=aaa></div>'); elm.appendTo('p'); divId++; }); $("p").click(function(e){ var elmType = $(e.target)[0].nodeName, elmId = $(e.target)[0].id; return displayVals(elmId); }); function displayVals(elmId) { var iwidth = $("#width").val(); var iheight = $("#height").val(); $("#"+elmId).css({width:iwidth, height:iheight}); console.log(elmId); } $("select").change(displayVals); displayVals(); </script>

  • CSS Ease-in-out to full screen

    - by Aditya Singh
    I have a black background div of a size which contains an image. <div id="Banner"> <img onclick="expand();" src="hola.jpg"> </div> #Banner { position:relative; height:50px; width:50px; margin:0 auto; background-color:#000000; -webkit-transition: all 0.5s ease-in-out 0.5s; -moz-transition: all 0.5s ease-in-out 0.5s; -o-transition: all 0.5s ease-in-out 0.5s; transition: all 0.5s ease-in-out 0.5s; } <script type="text/javascript"> function expand(){ document.getElementById('Banner').style['height'] = '250'; document.getElementById('Banner').style['width'] = '250'; } </script> So when the user clicks on the image, the div transitions to 250, 250. My problem is that, i want it to to transition to full screen. The following javascript function does expand to fullscreen but the transition effect doesn't come. I need to do it from a javascript code without jquery. function expand(){ document.getElementById('Banner').style['position'] = 'absolute'; document.getElementById('Banner').style['height'] = '100%'; document.getElementById('Banner').style['width'] = '100%'; document.getElementById('Banner').style['top'] = '0'; document.getElementById('Banner').style['left'] = '0'; } Please advice. Update : Solution Roger below has provided with an alternative solution. This takes care if the document has already been scrolled and is another place. Will expand the div to full browser screen. sz=getSize(); //function returns screen width and height in pixels currentWidth=200; currentHeight=200; scalex=sz.W/currentWidth; scaley=sz.H/currentHeight; transx=0-((expandingDiv.offsetLeft+(currentWidth/2))-(sz.W/2))+document.body.scrollLeft; transy=0-((expandingDiv.offsetTop+(cuttentHeight/2))-(sz.H/2))+document.body.scrollTop; transx = transx.toString(); transy = transy.toString(); document.getElementById("Banner").style['-webkit-transform'] = 'translate('+transx+'px,'+transy+'px) scale('+scalex+','+scaley+')';

  • Performance issues in android game

    - by user1446632
    I am making an android game, but however, the game is functioning like it should, but i am experiencing some performance issues. I think it has something to do with the sound. Cause each time i touch the screen, it makes a sound. I am using the standard MediaPlayer. The method is onTouchEvent() and onPlaySound1(). Could you please help me with an alternate solution for playing the sound? Thank you so much in advance! It would be nice if you also came up with some suggestions on how i can improve my code.

  • Android , Read in binary data and write it to file

    - by Shpongle
    Hi all , Im trying to read in image file from a server , with the code below . It keeps going into the exception. I know the correct number of bytes are being sent as I print them out when received. Im sending the image file from python like so #open the image file and read it into an object imgfile = open (marked_image, 'rb') obj = imgfile.read() #get the no of bytes in the image and convert it to a string bytes = str(len(obj)) #send the number of bytes self.conn.send( bytes + '\n') if self.conn.sendall(obj) == None: imgfile.flush() imgfile.close() print 'Image Sent' else: print 'Error' Here is the android part , this is where I'm having the problem. Any suggestions on the best way to go about receiving the image and writing it to a file ? //read the number of bytes in the image String noOfBytes = in.readLine(); Toast.makeText(this, noOfBytes, 5).show(); byte bytes [] = new byte [Integer.parseInt(noOfBytes)]; //create a file to store the retrieved image File photo = new File(Environment.getExternalStorageDirectory(), "PostKey.jpg"); DataInputStream dis = new DataInputStream(link.getInputStream()); try{ os =new FileOutputStream(photo); byte buf[]=new byte[1024]; int len; while((len=dis.read(buf))>0) os.write(buf,0,len); Toast.makeText(this, "File recieved", 5).show(); os.close(); dis.close(); }catch(IOException e){ Toast.makeText(this, "An IO Error Occured", 5).show(); } EDIT: I still cant seem to get it working. I have been at it since and the result of all my efforts have either resulted in a file that is not the full size or else the app crashing. I know the file is not corrupt before sending server side. As far as I can tell its definitely sending too as the send all method in python sends all or throws an exception in the event of an error and so far it has never thrown an exception. So the client side is messed up . I have to send the file from the server so I cant use the suggestion suggested by Brian .

  • Implementing hoverIntent for Drop Down Menu (coming from click_event)

    - by stormeTrooper
    I've just recently started programming, I was hoping for some help. I have a drop down menu that was originally activated by click_event, however I want to now implement hoverIntent in order to make the menu drop. The issue I am having now is being able to use the menu, because whenever I invoke the menu now, once I leave the area that activates the menu, the menu closes. If you could explain to me like I'm five, I'd appreciate it, thanks :) The code I am using as follows: JavaScript: function setupUserConfigMenu() { $('.user_profile_btn').hoverIntent( function (event) { $('#user_settings_dropdown').animate({height:['toggle', 'swing'] }, 225); }, function (event) { $('#user_settings_dropdown').animate({height:['toggle', 'swing'] }, 225); }) } HTML: <li> <a href="<%= "#" %>" class="user_profile_btn" title="Your profile page"><%= truncate(current_user.full_name || current_user.name, :length => 28) %> <div class="arrow_down"></div></a> <ul id="user_settings_dropdown"> <li> <a href="<%= current_user.get_url(true) %>"> <%= image_tag current_user.get_thumb_url, :size => "30x30" %> <div> <%= truncate(current_user.full_name || current_user.name, :length => 40) %> <br> View profile </div> </a> </li> <div class="grey_line"></div> <li class="settings_list_item"> <%= link_to "Settings", edit_user_registration_path %> </li> <li class="settings_list_item"> <%= link_to "About", "/about" %> </li> <li class="settings_list_item"> <%= link_to "Logout", destroy_user_session_path, :method => :delete %> </li> </ul> </li>

  • [C++] std::string manipulation: whitespace, "newline escapes '\'" and comments #

    - by rubenvb
    Kind of looking for affirmation here. I have some hand-written code, which I'm not shy to say I'm proud of, which reads a file, removes leading whitespace, processes newline escapes '\' and removes comments starting with #. It also removes all empty lines (also whitespace-only ones). Any thoughts/recommendations? I could probably replace some std::cout's with std::runtime_errors... but that's not a priority here :) const int RecipeReader::readRecipe() { ifstream is_recipe(s_buffer.c_str()); if (!is_recipe) cout << "unable to open file" << endl; while (getline(is_recipe, s_buffer)) { // whitespace+comment removeLeadingWhitespace(s_buffer); processComment(s_buffer); // newline escapes + append all subsequent lines with '\' processNewlineEscapes(s_buffer, is_recipe); // store the real text line if (!s_buffer.empty()) v_s_recipe.push_back(s_buffer); s_buffer.clear(); } is_recipe.close(); return 0; } void RecipeReader::processNewlineEscapes(string &s_string, ifstream &is_stream) { string s_temp; size_t sz_index = s_string.find_first_of("\\"); while (sz_index <= s_string.length()) { if (getline(is_stream,s_temp)) { removeLeadingWhitespace(s_temp); processComment(s_temp); s_string = s_string.substr(0,sz_index-1) + " " + s_temp; } else cout << "Error: newline escape '\' found at EOF" << endl; sz_index = s_string.find_first_of("\\"); } } void RecipeReader::processComment(string &s_string) { size_t sz_index = s_string.find_first_of("#"); s_string = s_string.substr(0,sz_index); } void RecipeReader::removeLeadingWhitespace(string &s_string) { const size_t sz_length = s_string.size(); size_t sz_index = s_string.find_first_not_of(" \t"); if (sz_index <= sz_length) s_string = s_string.substr(sz_index); else if ((sz_index > sz_length) && (sz_length != 0)) // "empty" lines with only whitespace s_string.clear(); } Some extra info: the first s_buffer passed to the ifstream contains the filename, std::string s_buffer is a class data member, so is std::vector v_s_recipe. Any comment is welcome :)

  • Problem with pointers and getstring function

    - by volting
    I am trying to write a function to get a string from the uart1. Its for an embedded system so I don't want to use malloc. The pointer that is passed to the getstring function seems to point to garbage after the gets_e_uart1() is called. I don't use pointers too often so I'm sure it is something really stupid and trivial that Im doing wrong. Regards, V int main() { char *ptr = 0; while(1) { gets_e_uart1(ptr, 100); puts_uart1(ptr); } return 0; }*end main*/ //------------------------------------------------------------------------- //gets a string and echos it //returns 0 if there is no error char getstring_e_uart1(char *stringPtr_, const int SIZE_) { char buffer_[SIZE_]; stringPtr_ = buffer_; int start_ = 0, end_ = SIZE_ - 1; char errorflag = 0; /*keep geting chars until newline char recieved*/ while((buffer_[start_++] = getchar_uart1())!= 0x0D) { putchar_uart1(buffer_[start_]);//echo it /*check for end of buffer wraparound if neccesary*/ if(start_ == end_) { start_ = 0; errorflag = 1; } } putchar_uart1('\n'); putchar_uart1('\r'); /*check for end of buffer wraparound if neccesary*/ if(start_ == end_) { buffer_[0] = '\0'; errorflag = 1; } else { buffer_[start_++] = '\0'; } return errorflag; } Update: I decided to go with approach of passing a pointer an array to the function. This works nicely, thanks to everyone for the informative answers. Updated Code: //------------------------------------------------------------------------- //argument 1 should be a pointer to an array, //and the second argument should be the size of the array //gets a string and echos it //returns 0 if there is no error char getstring_e_uart1(char *stringPtr_, const int SIZE_) { char *startPtr_ = stringPtr_; char *endPtr_ = startPtr_ + (SIZE_ - 1); char errorflag = 0; /*keep geting chars until newline char recieved*/ while((*stringPtr_ = getchar_uart1())!= 0x0D) { putchar_uart1(*stringPtr_);//echo it stringPtr_++; /*check for end of buffer wraparound if neccesary*/ if(stringPtr_ == endPtr_) { stringPtr_ = startPtr_; errorflag = 1; } } putchar_uart1('\n'); putchar_uart1('\r'); /*check for end of buffer wraparound if neccesary*/ if(stringPtr_ == endPtr_) { stringPtr_ = startPtr_; *stringPtr_ = '\0'; errorflag = 1; } else { *stringPtr_ = '\0'; } return errorflag; }

  • sub menu border calls onmouseout event

    - by insanepaul
    I've created a simple menu and submenu with tags(not allowed to use ul elements). To access the submenu the user hovers their mouse over the menu item. I use the onmouseover and onmouseout events to either show or hide the sub menu depending on which item is selected. A pipe (|) is used to seperate each submenu item and this is what is causing me problems. When a user hovers their mouse above the pipe character the subMenu div calls the onmouseout event which is not what I want. So I added padding around the pipe character and a minus margin so that there were no gaps between the pipe character and the other elements. This worked for all browsers including IE8. But in IE7 (I haven't tested IE6 yet) the submenu div calls the onmouseout event when I touch the top bit of either the left or right border of the pipe character span element. <div id="subMenu" onmouseout="hideSubMenu()" > <div id="opinionSubMenu" onmouseover="showOpinionSubMenu()"> <a id="Blogs" href="HTMLNew.htm">BLOGS</a> <span class="SubMenuDelimiter">|</span> <a id="Comments" href="HTMLNew.htm">COMMENTS</a> <span class="SubMenuDelimiter">|</span> <a id="Views" href="HTMLNew.htm">VIEWS</a> </div> <div id="learningSubMenu" onmouseover="showLearningSubMenu()"> <a id="Articles" href="HTMLNew.htm">ARTICLES</a> <span class="SubMenuDelimiter">|</span> <a id="CoursesCases" href="HTMLNew.htm">COURSES & CASES</a> <span class="SubMenuDelimiter">|</span> <a id="PracticeImpact" href="HTMLNew.htm">PRACTICE IMPACT</a> </div> </div> This is my css class #subMenu{ padding:10px 0px; background-color:#F58F2D; font-weight:normal; text-decoration:none; font-family:Lucida Sans Unicode; font-size:14px; float:left; width:100%; display:none;} #Blogs, #Comments, #Views, #Articles { padding:10px 5px; background:none repeat scroll 0 0 transparent; color:#000000; font-weight:normal; text-decoration:none; border:solid 1px black;} #Blogs:hover, #Comments:hover, #Views:hover, #Articles:hover{ color:#ffffff; text-decoration:none;} .SubMenuDelimiter{ padding:10px 5px; margin:10px -5px;}

  • Visual Studio 2010 and Test Driven Development

    - by devoured elysium
    I'm making my first steps in Test Driven Development with Visual Studio. I have some questions regarding how to implement generic classes with VS 2010. First, let's say I want to implement my own version of an ArrayList. I start by creating the following test (I'm using in this case MSTest): [TestMethod] public void Add_10_Items_Remove_10_Items_Check_Size_Is_Zero() { var myArrayList = new MyArrayList<int>(); for (int i = 0; i < 10; ++i) { myArrayList.Add(i); } for (int i = 0; i < 10; ++i) { myArrayList.RemoveAt(0); } int expected = 0; int actual = myArrayList.Size; Assert.AreEqual(expected, actual); } I'm using VS 2010 ability to hit ctrl + . and have it implement classes/methods on the go. I have been getting some trouble when implementing generic classes. For example, when I define an .Add(10) method, VS doesn't know if I intend a generic method(as the class is generic) or an Add(int number) method. Is there any way to differentiate this? The same can happen with return types. Let's assume I'm implementing a MyStack stack and I want to test if after I push and element and pop it, the stack is still empty. We all know pop should return something, but usually, the code of this test shouldn't care for it. Visual Studio would then think that pop is a void method, which in fact is not what one would want. How to deal with this? For each method, should I start by making tests that are "very specific" such as is obvious the method should return something so I don't get this kind of ambiguity? Even if not using the result, should I have something like int popValue = myStack.Pop() ? How should I do tests to generic classes? Only test with one generic kind of type? I have been using ints, as they are easy to use, but should I also test with different kinds of objects? How do you usually approach this? I see there is a popular tool called TestDriven for .NET. With VS 2010 release, is it still useful, or a lot of its features are now part of VS 2010, rendering it kinda useless? Thanks

  • AJAX: Problems returning multiple variables

    - by fwaokda
    First off sorry if I'm missing something simple just started working with AJAX today. I have an issue where I'm trying to get information from my database, but different records have different amounts of values. For instance, each record has a "features" column. In the features column I store a string. (ex: Feature1~Feature2~Feature3~Feature4... ) When I'm building the object I take apart the string and store all the features into an array. Some objects can have 1 feature others can have up to whatever. So... how do I return this values back to my ajax function from my php page? Below is my ajax function that I was trying and I'll provide a link with my php file. [ next.php : http://pastebin.com/SY74jV7X ] $("a#next").click(function() { $.ajax({ type : 'POST', url : 'next.php', dataType : 'json', data : { nextID : $("a#next").attr("rel") }, success : function ( data ) { var lastID = $("a#next").attr("rel"); var originID = $("a#next").attr("rev"); if(lastID == 1) { lastID = originID; } else { lastID--; } $("img#spotlight").attr("src",data.spotlightimage); $("div#showcase h1").text(data.title); $("div#showcase h2").text(data.subtitle); $("div#showcase p").text(data.description); $("a#next").attr("rel", lastID); for(var i=0; i < data.size; i++) { $("ul#features").append("<li>").text(data.feature+i).append("</li>"); } /* for(var j=1; j < data.picsize; j++) { $("div.thumbnails ul").append("<li>").text(data.image+j).append("</li>"); } */ }, error : function ( XMLHttpRequest, textStatus, errorThrown) { $("div#showcase h1").text("An error has occured: " + errorThrown); } }); });

  • Stretching DIV to 100% height and width of window but not less than 800x600px

    - by El Eme
    I have a page that needs to stretch and resize with with window and I've managed to do that but I need that the "inner div" (#pgContent) stretch if the window is resized to higher dimensions but that it doesn't shrink more than, let's say for example 800 x 600 px. As I have it now it stretches well but it also shrinks more than I want! It's working as I want in width but not in height!? Here's a visual example: My CSS: * { margin: 0; padding: 0; outline: 0; } /*| PAGE LAYOUT |*/ html, body { height: 100%; width: 100%; /*text-align: center;*/ /*IE doesn't ~like this*/ cursor: default; } #pgWrapper { z-index: 1; min-height: 100%; height: auto !important; /*min-height: 600px;*/ /* THIS SHOULD WORK BUT IT DOESN'T */ height: 100%; min-width: 1000px; width: 100%; position: absolute; overflow: hidden; text-align: center; background: #000; } #pgContent { position: absolute; top: 30px; left: 30px; right: 30px; bottom: 50px; overflow: hidden; background: #CCC; } #footWrapper { z-index: 2; height: 50px; min-width: 940px; position: absolute; left: 30px; right: 30px; bottom: 0px; background: #C00; } /*| END PAGE LAYOUT |*/ And the HTML: <body> <div id="pgWrapper"> <div id="pgContent"> This DIV should stretch with window but never lower than for example 800px x 600px!<br /> If window size is lower then scrollbars should appear. </div> </div> <div id="footWrapper"> <div id="footLft"></div> <div id="footRgt"></div> </div> </body> If someone could give me a help on this I would appreciate. Thanks in advance.

I created a ListBox to display bound elements, first off here is (a part) of my XAML. <Grid Grid.Row="2" Background="#EEEEEE"> <Border Margin="6,10,10,10" BorderBrush="#666666" BorderThickness="1"> <ListBox ItemsSource="{Binding}" Name="appList" BorderThickness="0" HorizontalContentAlignment="Stretch" HorizontalAlignment="Stretch"> <ItemsControl.ItemTemplate> <DataTemplate> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="80" /> <ColumnDefinition Width="*" /> </Grid.ColumnDefinitions> <Border Grid.Column="0" Margin="5" BorderThickness="3" CornerRadius="2" BorderBrush="Black" HorizontalAlignment="Left" VerticalAlignment="Top" x:Name="ItemBorder"> <Image Width="64" Height="64" Source="{Binding Path=IconUri}" Stretch="UniformToFill" /> </Border> <StackPanel Margin="0,5,5,5" Grid.Column="1" Orientation="Vertical" HorizontalAlignment="Stretch"> <TextBlock FontSize="18" Text="{Binding Path=DisplayName}" /> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="*" /> <ColumnDefinition Width="60"/> </Grid.ColumnDefinitions> <ProgressBar Grid.Column="0" Height="24" HorizontalAlignment="Stretch" IsIndeterminate="{Binding Path=IsDiscovering}" Value="{Binding Path=PercentageDownloaded}" /> <TextBlock Grid.Column="1" HorizontalAlignment="Center" VerticalAlignment="Center"><TextBlock x:Name="percentageDownloaded" /><TextBlock x:Name="percentageMeter">%</TextBlock></TextBlock> </Grid> </StackPanel> </Grid> <DataTemplate.Triggers> <DataTrigger Binding="{Binding Path=IsDiscovering}"> <DataTrigger.Value>True</DataTrigger.Value> <Setter TargetName="percentageDownloaded" Property="Text" Value="N/A" /> <Setter TargetName="percentageMeter" Property="Visibility" Value="Collapsed" /> </DataTrigger> <DataTrigger Binding="{Binding Path=IsDiscovering}"> <DataTrigger.Value>False</DataTrigger.Value> <Setter TargetName="percentageDownloaded" Property="Text" Value="{Binding Path=PercentageDownloaded}" /> <Setter TargetName="percentageMeter" Property="Visibility" Value="Visible" /> </DataTrigger> </DataTemplate.Triggers> </DataTemplate> </ItemsControl.ItemTemplate> </ListBox> </Border> </Grid> Sizing the window up stretches the ListBox content just fine, but when I size it down, it retains it's width and spawns vertical scrollbars.

  • Can I mix declarative and programmatic layout in GWT 2.0?

    - by stuff22
    I'm trying to redo an existing panel that I made before GWT 2.0 was released. The panel has a few text fields and a scrollable panel below in a VerticalPanel. What I'd like to do is to make the scrollable panel with UIBinder and then add that to a VerticalPanel Below is an example I created to illustrate this: public class ScrollTablePanel extends ResizeComposite{ interface Binder extends UiBinder<Widget, ScrollTablePanel > { } private static Binder uiBinder = GWT.create(Binder.class); @UiField FlexTable table1; @UiField FlexTable table2; public Test2() { initWidget(uiBinder.createAndBindUi(this)); table1.setText(0, 0, "testing 1"); table1.setText(0, 1, "testing 2"); table1.setText(0, 2, "testing 3"); table2.setText(0, 0, "testing 1"); table2.setText(0, 1, "testing 2"); table2.setText(0, 2, "testing 3"); table2.setText(1, 0, "testing 4"); table2.setText(1, 1, "testing 5"); table2.setText(1, 2, "testing 6"); } } then the xml: <ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder' xmlns:g='urn:import:com.google.gwt.user.client.ui' xmlns:mail='urn:import:com.test.scrollpaneltest'> <g:DockLayoutPanel unit='EM'> <g:north size="2"> <g:FlexTable ui:field="table1"></g:FlexTable> </g:north> <g:center> <g:ScrollPanel> <g:FlexTable ui:field="table2"></g:FlexTable> </g:ScrollPanel> </g:center> </g:DockLayoutPanel> </ui:UiBinder> Then do something like this in the EntryPoint: public void onModuleLoad() { VerticalPanel vp = new VerticalPanel(); vp.add(new ScrollTablePanel()); vp.add(new Label("dummy label text")); vp.setWidth("100%"); RootLayoutPanel.get().add(vp); } But when I add the ScrollTablePanel to the VerticalPanel, only the first FlexTable (test1) is visible on the page, not the whole ScrollTablePanel. Is there a way to make this work where it is possible to mix declarative and programmatic layout in GWT 2.0?

  • circles and triangles problem

    - by Faken
    Hello everyone, I have an interesting problem here I've been trying to solve for the last little while: I have 3 circles on a 2D xy plane, each with the same known radius. I know the coordinates of each of the three centers (they are arbitrary and can be anywhere). What is the largest triangle that can be drawn such that each vertice of the triangle sits on a separate circle, what are the coordinates of those verticies? I've been looking at this problem for hours and asked a bunch of people but so far only one person has been able to suggest a plausible solution (though i have no way of proving it). The solution that we have come up with involves first creating a triangle about the three circle centers. Next we look at each circle individually and calculate the equation of a line that passes through the circle's center and is perpendicular to the opposite edge. We then calculate two intersection points of the circle. This is then done for the next two circles with a result of 6 points. We iterate over the 8 possible 3 point triangles that these 6 points create (the restriction is that each point of the big triangle must be on a separate circle) and find the maximum size. The results look reasonable (at least when drawn out on paper) and it passes the special case of when the centers of the circles all fall on a straight line (gives a known largest triangle). Unfortunate i have no way of proving this is correct or not. I'm wondering if anyone has encountered a problem similar to this and if so, how did you solve it? Note: I understand that this is mostly a math question and not programming, however it is going to be implemented in code and it must be optimized to run very fast and efficient. In fact, I already have the above solution in code and tested to be working, if you would like to take a look, please let me know, i chose not to post it because its all in vector form and pretty much impossible to figure out exactly what is going on (because it's been condensed to be more efficient). Lastly, yes this is for school work, though it is NOT a homework question/assignment/project. It's part of my graduate thesis (abet a very very small part, but still technically is part of it). Thanks for your help.

  • Calling back a functions value

    - by Jason Kelly
    I need your help, I cannot, for the life of me, figure this out. I've had my head wrapped around it only to no avail. Ideally, i'd like to setup two functions. 1 function: select_date() to interact with the user to select a date from the jQuery Date picker. If the dialog is closed then return as null. Then a second function: test() to check wether or not a date was picked/selected.' Here's my delema, when the function test() is executed, an alert box pops up and says "undefined" which means, I never get to select a date and it always being "undefined" I dont see what I am doing wrong here and everything seems logical to me. <!DOCTYPE html> <html> <head> <link href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.21/themes/base/jquery-ui.css" rel="stylesheet" type="text/css"/> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.js"></script> <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.21/jquery-ui.js"></script> <script type="text/javascript"> function select_date() { var sdate $('#dd').dialog({ autoOpen: true, modal: true, overlay: { opacity: 0.5, background: 'black' }, title: "title", height: 265, width: 235, draggable: false, resizable: false }); $('#d1').datepicker({ onSelect: function () { $("#dd").dialog("close"); } }); return sdate } function test() { var x = select_date() alert(x) } </script> <style type="text/css"> #d1 {font-size:64%;} </style> </head> <body> <div id="dd"> <div id="d1"> </div> </div> <a href="javascript:test()">test</a> </body> </html>

  • What's causing this background-image to display "incorrectly" in Opera and Firefox?

    - by Sukasa
    I know this is something I'm probably doing wrong, so please don't incinerate me for the thread title. I'm trying to put together a small personal website using HTML 5/CSS3. I've checked with the w3c validator and the site and CSS file fully conform according to the validator (However the validator has a warning attached that it might not be perfect). I'm not sure how to explain it without a picture, so here's a comparison of Chrome/Opera/Firefox: So, you can sorta see how in Chrome the background image is in one non-repeating piece, whereas in Opera/Firefox the image has, oddly, been broken up and placed slightly differently. I'm confident this is due to an error on my part, but I've had no luck at all figuring out why the image is being mangled in Opera and Firefox. Here's the CSS that's relevant to this issue: /* Content Pane */ .content { position: absolute; left: 220px; width: 800px; top: 80px; min-height: 550px; background-color: rgba(8,12,42,0.85); } /* Headers */ .content hgroup { background: url("Header_Flat.png") no-repeat left top; min-height: 38px; padding-left: 28px; text-shadow: 0 0 8px #FFA9FF; color: Black; text-decoration: none; } .content hgroup h1 { display: block; } .content hgroup h3 { display: inline; position: relative; top: -12px; left: 20px; text-shadow: 0 0 6px #AFF9FF; } .content hgroup h4 { display: inline; position: relative; top: -12px; left: 20px; font-size: xx-small; text-shadow: 0 0 6px #AFF9FF; } And the HTML: <hgroup> <h1>New Site!</h1> <h3>Now with Bloom!</h3> <h4> - Posted Tuesday, May 11th 2010</h4> </hgroup> Can anyone see what I'm doing wrong?

  • Write to text file using ArrayList

    - by Ugochukwutubelum Chiemenam
    The program is basically about reading from a text file, storing the current data into an ArrayList, then writing data (from user input) into the same text file. Kindly let me know where I am going wrong in this sub-part? The data inside the text file is as follows: abc t1 1900 xyz t2 1700 The compiler is showing an error at the line output.format("%s%s%s%n", public class justTesting { private Scanner input; private Formatter output; private ArrayList<Student> tk = new ArrayList<Student>(); public static void main(String[] args) { justTesting app = new justTesting(); app.create(); app.writeToFile(); } public void create() { Text entry = new Text(); Scanner input = new Scanner(System.in); System.out.printf("%s\n", "Please enter your name, ID, and year: "); while (input.hasNext()) { try { entry.setName(input.next()); entry.setTelNumber(input.next()); entry.setDOB(input.next()); for (int i = 0; i < tk.size(); i++) { output.format("%s%s%s%n", tk.get(i).getName(), tk.get(i) .getTelNumber(), tk.get(i).getDOB()); } } catch (FormatterClosedException fce) { System.err.println("Error writing to file."); return; } catch (NoSuchElementException nsee) { System.err.println("Invalid input. Try again: "); input.nextLine(); } System.out.printf("%s\n", "Please enter your name, ID, and year: "); } } public void writeToFile() { try { output = new Formatter("testing.txt"); } catch (SecurityException se) { System.err .println("You do not have write access permission to this file."); System.exit(1); } catch (FileNotFoundException fnfe) { System.err.println("Error opening or creating file."); System.exit(1); } } }
