• ListView GridView and Grid

  - by urema

  Hi, If you have a ListView with its view set as a GridView, which itself contains columns for each month say.....how do I set a template up for the ItemTemplate of the ListView so that each Item will be three rows high, and be inline with the ListView.View's columns? For example different employee recruits over a year.... each month across the top and each employee on the left side, though sub-columned on the employee are three rows "Name", "Address" and "Job Type" say. I know you have to use the IsSharedSizeScope attached property. January February ... Employee1 Name E1 Address E1 Street Job Type Cleaner Employee2 Name ... Address ... Job Type ... Thanks greatly in advance, U.

• Scala, represent pattern of boolean tuple into something else.

  - by Berlin Brown

  This is a cellular automata rule (input Boolean == Left, Center, Right Cell) and output Boolean . What is a better way to represent this in Scala. trait Rule { def ruleId() : Int def rule(inputState:(Boolean, Boolean, Boolean)) : Boolean override def toString : String = "Rule:" + ruleId } class Rule90 extends Rule { def ruleId() = 90 def rule(inputState:(Boolean, Boolean, Boolean)) : Boolean = { // Verbose version, show all 8 states inputState match { case (true, true, true) => false case (true, false, true) => false case (false, true, false) => false case (false, false, false) => false case _ => true } } }

• How to center text in a select list

  - by Micah

  I'm having trouble styling a select list in an html form. Basically I want it to have a font size of 12px, and a height of 30px; The problem is that the box is drawn to the right hight, but the text rendering varies in each browser. In FireFox it renders it in the top left corner. I want to vertically center the text. Anyone know of a way to do this or do I need to make something custom out of a ul? Thanks

  Hi, I have this code: CGPoint arrowMiddle = CGPointMake((arrowOne.x + arrowTo.x)/2, (arrowOne.y + arrowTo.y)/2); CGPoint arrowLeft = CGPointMake(arrowMiddle.x-40, arrowMiddle.y); CGPoint arrowRight = CGPointMake(arrowMiddle.x, arrowMiddle.y + 40); [arrowPath addLineToScreenPoint:arrowLeft]; [arrowPath addLineToScreenPoint:arrowMiddle]; [arrowPath addLineToScreenPoint:arrowRight]; [[mapContents overlay] addSublayer:arrowPath]; [arrowPath release]; with this output: http://yfrog.com/edschermafbeelding2010032p What have i to add to get the left and right the at same degree of the line + 30°.

• jquery "this" binding issue on event handler

  - by clyfe

  In jquery an event hadler's binding is the event generating DOM element (this points to the dom element). In prototype to change the binding of an event handler one can use the bindAsEventListener function; How can I access both the instance and the DOM element from a event handler? Similar to http://stackoverflow.com/questions/117361/how-can-i-bind-an-event-handler-to-an-instance-in-jquery function Car(){ this.km = 0; $("#sprint").click(this.drive); //setup event handler } // event handler // in it I need to access both the clicked element // and the binding object (instance of car) Car.prototype.drive = function(){ this.km += 10; // i'd like to access the binding (but jq changes it) this.css({ left: this.km }); // also the element // NOTE that is inside this function I want to access them not elsewhere } var car = new Car();

• How to call operator<< on "this" in a descendant of std::stringstream?

  - by romkyns

  class mystream : public std::stringstream { public: void write_something() { this << "something"; } }; This results in the following two compile errors on VC++10: error C2297: '<<' : illegal, right operand has type 'const char [10]' error C2296: '<<' : illegal, left operand has type 'mystream *const ' Judging from the second one, this is because what this points at can't be changed, but the << operator does (or at least is declared as if it does). Correct? Is there some other way I can still use the << and >> operators on this?

• spliiting code in java-don't know what's wrong [closed]

  - by ???? ?????

  I'm writing a code to split a file into many files with a size specified in the code, and then it will join these parts later. The problem is with the joining code, it doesn't work and I can't figure what is wrong!

• CASE + IF MysQL query

  - by terence6

  Problem is as follows. I have a product that can be in one of three categories (defined by category_id). Each category table has category_id field related to category_id in product table. So I have 3 cases. I'm checking If my product.category_id is in table one. If yes, I take some values. If not I check in tables that are left. What can I write In the ELSE section? Can anyone correct my query ? CASE WHEN IF EXISTS(SELECT * FROM table1 WHERE category_id='category_id') THEN SELECT type_id FROM table1 WHERE category_id='category_id'; WHEN IF EXISTS(SELECT * FROM table2 WHERE category_id='category_id') THEN SELECT value_id FROM table2 WHERE category_id='category_id'; WHEN IF EXISTS(SELECT * FROM table3 WHERE category_id='category_id') THEN SELECT group_id FROM table3 WHERE category_id='category_id'; ELSE "dont know what here"; END;

• Use CSS (and maybe JavaScript) to make an element be square (or maintain a specific aspect ratio)

  - by David Pfeffer

  I have a div that I want to have the following characteristics: Width = 50% of its parent element Height equal to whatever it needs to be in order to maintain a certain aspect ratio. I need to use percentages because the object will resize left-right when the browser is resized. I want the object to be resized top-bottom to ensure the object maintains the same aspect ratio. I don't think there's any way to use pure CSS to do this, but does anyone know of a way? Alternatively, is there an easy JavaScript way to do this? (JQuery is fine.)

• building website with menu without using frames

  - by kms333

  With Dreamweaver, I use frames to define a left column menu, and clicking on each menu tab would change the html page displayed on the right frame. However, webdesign tools such as kompozer do not support frames. 1 - What is the best way to design a html personal webpage with such menu bars, without using frames ? 2 - If html is not enough, what other scripting languages would you recommend to learn for someone with Java background and have basic knowledge of html and css. 3 - What web-design tools would you recommend to build a personal website ?

• How to make a div expand vertically to wrpa the content within it?

  - by MalcomTucker

  I have a div which wraps a number of images that are generated dynamically. I don't know how high the list of images is. My problem is the div that contains the dynamically generated images doesn't behave like it is housing any content - I want it to extend to the height of the list of images. Each image is itself wrapped in a div. This is the wrapper div: .block { padding:10px; margin-top:10px; height:auto; background-color:#f9f9f9; } This is the markup dynamically generated for (one of) the images: <div class="block"> <div style="float: left; padding: 2px 2px 2px 2px;"><IMG SRC="45.jpg" BORDER="0"/></div> ..... How do I get the block div to extend down with the images? Thanks

• Why Does TFS Allow Orphaned Content and How Do I Get Rid of It?

  - by Chad

  My TfsVersionControl database has grown to 40+ GB in size. We recently did a TFS Destroy on a folder tree that should have cleared up at least 10 GB but instead it seemed to have no effect. When I look at the tables in TfsVersionControl, I am first shocked to see that there are no foreign keys at all in the database. Running a few queries, I see that there is some orphaning going on: tbl_Content has 13.9 GB of records that don't have a related tbl_File record tbl_File and tbl_Content have 2.4 GB that don't have a related tbl_Namespace record The cleanup job seems to be running nightly (prc_DeleteUnusedContent) and running it against the database manually doesn't remove any orphans. I see in the log for the cleanup job that it failed on 3/16, which is the morning after I destroyed the large amount of data. The error was due to a full transaction log. Could that error be the reason I'm left with all this orphaned data that can't be deleted? How can I permanently destroy this unneeded content?

• Where do I put my php files to have Xampp parse them?

  - by CDeanMartin

  I finished installing Ubuntu 10 for netbooks, and XAMPP. The XAMPP website tutorial made it very easy to install, then left me high and dry. Everything works, but I have no idea where to put my handwritten php files. After a few hours of googling, and trying to understand the file explorer, I realized I have no idea where anything is in ubuntu. For an answer, please don't just tell me "go to "X" directory. I won't know how to navigate there. I also did a file search for htdocs with no luck.

• do people value information or aesthetic value of websites ? [closed]

  - by fwfwfw

  I'm thinking, why does the web have to be so colorful. meaning, all the information is buried deep beneath layers of flash, javascripts, html and images. Sure, a good positioning of these media files, create an aesthetic value but how important is it to the user ? moreover, aren't people looking for information after all ? why can't the internet be a uniform looking data warehouse ? now we've gotta digg through all the aesthetic junk, using shady web scraping techniques, unless RSS or API is provided. why can't we settle for just a dull grey button and framesets for navigation ? why can't all sites have navigation frame on the left and top ? why can't all sites put their damn data always in normalized table tag ?

Similarly I need to find out the next occurrence of CDS and calculate the time diff with the next row. This has to go on until there are no occurrences of CDS left in the table. Will be grateful if someone can help on this!!

• Trouble converting string/character to byte in lisp

  - by WanderingPhd

  I've some data that I'm reading in using read-line and I want to convert it into a byte-array. babel:string-to-octet works for the most part except when the character\byte is larger (above 200) in which case it returns two numbers. As an example, if the character is ú using babel:string-to-octet returns (195 185) instead of 250 which is what I'm looking for. I tried a number of encodings in babel but none of them seem to work. If I use read-byte or read-sequence it does read in 250. But for reasons of backward compatibility, I'm left with using read-line and I would like to know if there is something I'm missing when using babel:string-to-octet to convert ú to 250. I'm using ccl 1.8 btw.

• How would you write this Clojure snippet in Ruby and/or Haskell?

  - by dnolen

  I was working on a Rails template and was trying to write a bit of code that allows me to populate a table or multiple columns of ul tags "top-to-bottom" and "left-to-right" across however many columns I specify. I'm just getting the hang of Ruby so I couldn't figure this out. I'm also curious about an idiomatic Haskell version for this useful snippet. Improvements to Clojure version appreciated: (defn table [xs & {:keys [cols direction] :or {cols 1 direction 'right}}] (into [] (condp = direction 'down (let [c (count xs) q (int (/ c cols)) n (if (> (mod c q) 0) (inc q) q)] (apply map vector (partition n n (repeat nil) xs))) 'right (map vec (partition cols cols (repeat nil) xs))))) With this bit of code I can then do the following: (table (range 10) :cols 3) Printed out this would look like so: 0 1 2 3 4 5 6 7 8 9 And the trickier one: (table (range 10) :cols 3 :direction 'down) Looks like so: 0 4 8 1 5 9 2 6 3 7
