• Is it possible to upgrade from a clean install in Windows 8?

  - by Misha

  Does Windows 8 support upgrading from a clean install. For example, buying the upgrade key and entering it on a clear install? Or is it functionally necissary to have the version you are upgrading from installed on the computer. The former was the case with Windows 7, but I recal Windows 2000 needed the an installed copy before an update would proceed. I currently have a linux setup and I have the liceanse for Windows 7, but I don't want to have to downoad two 4 GB isos.

• Is dynamic evaluation of xpath variable string possible using .net 2.0 xslt implementation?

  - by Crocked

  Hi, I'm trying to evaluate an xpath varable I'm building dynamically based on the position of the node. I can create the xpath string in a variable but when I select the value of this just get the string and not the node set I need. I use the following to create the xpath <xsl:variable name="xpathstring" select="normalize-space(concat(&quot;//anAttribute[@key='pos&quot;,position(),&quot;']&quot;))"/> and try to output the value with the following. <xsl:value-of select="$xpathstring"/> If I execute the xpath in my debugger I get the nodeset but in my xml output only get the xpath string which looks like this //anAttribute[@key='pos1'] I had a look at exslt dyn:evaluate which seems to enable this but this seems to be only supported by certain processors and doesn't provide a standalone implementation or at least as far as I could see (currently using the standard .net 2.0 xslt whihc is only xslt 1.0 as far as I recall) Is there anyway to handle this without changing processor? Kind Regards, Crocked

• Checkbox not checking inside div in Firefox

  - by mike

  Weird problem. I don't know if anyone can shed some light on this? I have a checkbox inside a div. It works fine in IE but not Firefox. I have to click the space around the checkbox that is occupied by the div (sort of like a label) for the checkbox to tick on and off. Directly clicking the checkbox does not show it as ticked on or off, even though in firebug it is showing that it is in a checked state and an unchecked state. Only in FF does this happen.....

• Affine Transforms with Demo App

  - by Dex

  I have a demo app here https://github.com/rdetert/image-transform-test After importing an image, you can pinch, zoom, rotate the image. What I want to do is save out a 640x480 image (landscape mode) that looks identical to the live preview. So if there are 100px bars of empty space on the sides, I need the same empty bars in the final output (scaled appropriately). This is proving to be more difficult than I thought it would be. I can't quite get it to come out right after days of working on it. The magic method that generates the final image is called -(void)generateFinalImage Good luck! ;)

• 3 DIV's - Center Middle and Others taking up rest of room

  - by Adam

  I need to have 3 DIV's - you can see 3 colors in the above image. The middle DIV needs always be 960px and alls needs to be centered (you can see the 2 grey lines above). The other 2 DIV's need to take up all the other available space. If I zoom in and out of the page the red and yellow DIV's need to expand with the page while the middle green one remains centered. I've tried DIV solutions and Table solutions and I can't get it to fit. HTML <div id="div1" style="background-color:red"></div> <div id="div2" style="background-color:red"></div> <div id="div3" style="background-color:red"></div> any advice would be appreciated. thx ** Update: http://jsfiddle.net/scxAq/ working on this... with limited success...

• Protocol/Packet Design Questions

  - by cam

  I'm looking to a design a protocol for a client-server application and need some links to some resources that may help me. The big part is I'm trying to create my own "packet" format so I can minimize the amount of information being sent. I'm looking for some resources to dissect their protocol, but it seems some completely lack packet design, such as SMTP (which just sends strings terminated by CLRF). What are the advantages/disadvantages of using a system like SMTP over a system that uses a custom made packet? Couldn't SMTP use only a couple bytes to cover all commands through bit flags and save bandwidth/space? Just trying to get my head around all this.

• Context menu opens slowly in Explorer in Windows 7, why?

  - by xxzoid

  I'm running a Windows 7 on my reasonably modern laptop, when I open the context menu in Windows Explorer it really takes it time to show up (~10 seconds). There are some programs that have their commands added to it (an archive manipulation utility, an antivirus, a version control system and such). I think one of them freezes the operation. Is there a benchmark tool to measure it somehow or a tool to turn them off by one in Explorer without uninstalling them (which would be a penultimate measure, because use them)?

• Content Assist problem in eclipse 3.5

  - by user361996

  I've got a Content Assist problem in eclipse 3.5, which is eclipse-java-galileo-win32.zip. When I press Alt+/(I've changed Ctrl+Space to this) in Java Editor, no assistant tips are shown up. I've solved this problem and I'd like to share my experience. 1 Eclipse--Preferences--General--Keys; 2 Search 'Content Assist'; 3 You'll find that in 'When' Field, the default value is 'in dialogs and window', change it to 'Editing Java Source', then press 'OK' to save; I can not post a image, but here is a link: http://www.freeimagehosting.net/image.php?e0987ea847.png That's All.

• Notepad++ Move Caret Outside Bracket

  - by marknadal

  I've searched everywhere and can't find an answer to something incredibly simple and useful for Notepad++. When using autoclose, the cursor gets stuck inside, which is good until I've finished typing the parameters. How do I get the caret to jump outside of the currently nested autoclosed element? Regardless of it being (), {}, [], "", '', ? CTRL+B does does something similar, but it goes to the inside of the left bracket first, and then to the outside of the right bracket, which is where I want to be. This only works for brackets though, not tags and qoutations Hitting CTRL+B twice is cumbersome and manually hitting "right arrow" requires too much hand motion while coding. And finally, is there anyway I can map this to "SHIFT+Space"?

• Sorting array of 1000 distinct integers in the range [1, 5000], accessing each element at most once

  - by Cronydevil

  Suppose you have an array of 1000 integers. The integers are in random order, but you know each of the integers is between 1 and 5000 (inclusive). In addition, each number appears only once in the array. Assume that you can access each element of the array only once. Describe an algorithm to sort it. How i can sorting? If you used auxiliary storage in your algorithm, can you find an algorithm that remains O(n) space complexity?

• Add Expansion Button to Stackpanel

  - by scientist

  I'd like to add Elements to a StackPanel (or Listbox / Listview if it would make that easier) and automatically add a Button (like "...") to indicate that there are more children than there is space for. Consider a calendar that has appointment items in each day. If there are more appointments than as much as can be displayed a button is displayed to go to a detailed view for that day. Can this be done automatically, or how do I calculate the positions of the stackpanel and its items. It's for windows store development in c#. Thanks in advance.

• What is the most "database independent" way of creating a variable length text field in a database

  - by Thibaut Colar

  I want to create a text field in the database, with no specific size (it will store text of length unknown in some case) - the particular text are serialized simple object (~ JSON) What is the most database independent way to do this : - a varchar with no size specified (don't think all db support this) - a 'text' field, this seems to be common, but I don't believe it's a standard - a blob or other object of that kind ? - a varchar of a a very large size (that's inefficient and wastes disk space probably) - Other ? I'm using JDBC, but I'd like to use something that is supported in most DB (oracle, mysql, postgresql, derby, HSQL, H2 etc...) Thanks.

• Running multiple versions of PostgreSQL on the same Ubuntu server

  - by user51938

  I have PostgreSQL 8.4 and 9.0 running on the same server (Ubuntu Lucid). I installed them both via apt-get (8.4 with the default package sources, and 9.0 after adding the ppa from https://launchpad.net/~pitti/+archive/postgresql). When I run a command like "createdb" from the command line or start up the "psql" shell, PostgreSQL version 8.4 is used by default on my system. So, how do I force these commands to use PostgreSQL 9.0 instead of 8.4?

• Find a common element within N arrays

  - by kunjaan

  If I have N arrays, what is the best(Time complexity. Space is not important) way to find the common elements. You could just find 1 element and stop. Edit: The elements are all Numbers. Edit: These are unsorted. Please do not sort and scan. This is not a homework problem. Somebody asked me this question a long time ago. He was using a hash to solve the problem. I was thinking if SO has solved similar problems.

• Windows 7 Upgrade vs Full Edition?

  My dad already has a copy of Win 7 Pro (full). If I buy the upgrade edition of Win 7 Pro (student discount), could I use the full disk to install, then enter the new, upgrade key code to activate it? I can't seem to get a student discount for the full version.

• Why in the hell is this happening?

  - by user202411

  I just can't understand why is my database (mysql) behaving like this! My console shows that the record is created properly (please, notice the "remote_id" value): Tweet Create (0.3ms) INSERT INTO `tweets` (`remote_id`, `text`, `user_id`, `twitter_account_id`) VALUES (12325438258, 'jamaica', 1, 1) But when I check the record, it shows that the remote_id is 2147483647 intead of the provided value (12325438258 in the example above)... This table has many entries, but this field is always written with 2147483647... It was supposed to fill this space with an unique id (which I guarantee you is being generated properly).

• Htaccess/robots.txt to allow search bots to explore main domain but not directory on other domain

  - by gX

  Ok, I understand the Title didn't make any sense so here I've tried to explain it in detail. I'm using a hosting that gives me space for my domain and lets me "add on" other domains on it. So lets say I have a domain A, and I add on a domain B. Basically my hosting gives me a public_html where I can put stuff that shows when someone visits website A. But, when I add the domain B, it lets me put the content of B, INSIDE of that public_html so that website B.com can also be visited by going to A.com/siteB... Thats all good, except that Google has started indexing B.com as well as A.com/siteB, I'm ok with it indexing B.com, but I somehow want to prevent it from indexing A.com/siteB so that when people search for B, it doesn't end up showing A.com/siteB. Any ideas? Let me know if the question is still unclear.

• Likelihood of IOError during print vs. write

  - by jkasnicki

  I recently encountered an IOError writing to a file on NFS. There wasn't a disk space or permission issue, so I assume this was just a network hiccup. The obvious solution is to wrap the write in a try-except, but I was curious whether the implementation of print and write in Python make either of the following more or less likely to raise IOError: f_print = open('print.txt', 'w') print >>f_print, 'test_print' f_print.close() vs. f_write = open('write.txt', 'w') f_write.write('test_write\n') f_write.close() (If it matters, specifically in Python 2.4 on Linux).

• HTML block nested in PHP if statement - is this considered bad practice?

  - by JYelton

  Consider the following example: <table> <tr> <td>Row One</td> </tr> <?php if ($rowtwo) { ?> <tr> <td>Row Two</td> </tr> <?php } ?> </table> If $rowtwo is true, the second row is output, otherwise it is skipped. The code works as desired, however I am evaluating Netbeans (7 beta) as a PHP IDE (instead of just using a text editor). Netbeans flags the code with an error: Misplaced non-space characters insided [sic] a table. Should I consider an alternate way of writing this code, or is Netbeans incapable of understanding this flow control wrapper for HTML output?

• How to write a regular expression for "everything between X and Y" for use with preg_replace

  - by pg

  I want to take a variable called $encoded_str and and remove cd1, CD1 and anything between the first 'l' and the last blank space. So for example "lp6 id4 STRINGcd1" would return "STRING". I'm using PHP 4 for now so I can't use str_ireplace, I have this: $encoded_str=str_replace('CD1','',$encoded_str); $encoded_str=str_replace('cd1','',$encoded_str); $encoded_str=preg_replace('X','',$encoded_str); I've RTFM for preg_replace but am a bit confused. What should I replace the X with and can you suggest a decent introductory primer for writing regular expressions?

• How do I make a URL text a link?

  - by jpjp

  Say on Facebook or Twitter, when I type "www.google.com" and submit it, it becomes a link. How do I code this in PHP? Do I use regular expressions to get where the www starts and the .com ends? Is this how they do it? <?PHP //some regular expression to get www and .com part $link="<a href='$url'>$url</a>"; echo $link; ?> How do I write a regular expression to get the "www" and ".com" part? And for twitter's @obama, obama would become a link to obama's site. What regular expression do they use to get the text after the @ and before the space?
