• XSLT string with HTML entities - How can I get it to render as HTML?

  - by Kache4

  I'm completely new to using XSL, so if there's any information that I'm neglecting to include, just let me know. I have a string in my XSLT file that I can display like this: <xsl:value-of select="@Description/> and it shows up, rendered in a browser like: <div>My text has html entities within it</div> <div>This includes quotes, like &quot;Hello World&quot; and sometimes whitespaces.&nbsp;</div> What can I do to get this string rendered as html, so that <div></div> results in newlines, &quot; gives me ", and &nbsp gives me a space? I could elaborate on things I've already tried that haven't worked, but I don't know if that's relevant.

• How to Programmatically Identify a PI Font (a Dingbat) under OS X

  - by Glenn Howes

  There is a class of fonts called Pi fonts whose glyphs, under OS X, get mapped to the private Unicode space 0xF021-0xF0FF such that if you subtract 0xF000 from each unicode character to retrieve the 8-bit version of the character and be able to draw that character as if it were a standard Roman character. My question is how do I recognize these fonts? It's obvious the system can do so because there is a category on the Special Characters palette called "Pi Fonts" which apparently has the various such fonts installed on my system. In my case they are BookshelSymbolSeven, MSReferenceSpeciality, MT-Extras, Marlett, MonotypeSorts, Webdings, and various Wingdings. If I use the old fashioned QuickDraw routines to ask for the TextEncoding of these fonts, I get a value of 0x20000 which I do not see in the system header file TextCommon.h. Am I supposed to treat any font with a TextEncoding of 0x20000 as a Pi Font? And I'd rather not use any QuickDraw font handling routines for obvious reasons.

• How do I detect a loop in this linked list?

  - by jjujuma

  Say you have a linked list structure in Java. It's made up of Nodes: class Node { Node next; // some user data } and each Node points to the next node, except for the last Node, which has null for next. Say there is a possibility that the list can contain a loop - i.e. the final Node, instead of having a null, has a reference to one of the nodes in the list which came before it. What's the best way of writing boolean hasLoop(Node first) which would return true if the given Node is the first of a list with a loop, and false otherwise? How could you write so that it takes a finite amount of space and a reasonable amount of time?

• Thread Local Storage and local method variables

  - by miguel

  In c#, each thread has its own stack space. If this is the case, why is the following code not thread-safe? (It is stated that this code is thread-safe on this post: Locking in C# class Foo { private int count = 0; public void TrySomething() { count++; } } As count is an int (stack variable), surely this value would be isolated to an individual thread, on its own stack, and therefore thread-safe? I am probably missing something here, but I dont understand what is actually in Thread Local Storage if not stack-based variables for the thread?

• How to obtain Bing maps like InfoWindow in Google Maps?

  - by BillB

  I'm using Google Maps v3. I really like the InfoWindows found in Bing, as opposed to Google. Screenshots & functionality found here comparing the two: http://www.axismaps.com/blog/2009/07/data-probing-and-info-window-design-on-web-based-maps/ Question: How can I replicate Bing like InfoWindows while using Google Maps v3? UPDATE: To be more specific, what I like about Bing's InfoWindows include: - The pointer dynamically changes sides from left/right/bottom/top, as opposed to Google limited to only have the InfoWindow pointer on the bottom - Bing's InfoWindows use less space - You can configure Bing's InfoWindows to pop up outside of the map bounders so that you don't have to autopan the map to display the marker's InfoWindow

• excel vba: return values only if they are not present in current column

  - by every_answer_gets_a_point

  i have a column to which i am adding data from another column i would like to check whether that column has the data that i wish to add. can you help me wiht a formula that will tell me whether a certain value exists in the current column? please keep in mind it is a bit more complex than it sounds. currently i have this in the cell: =IF(OR(A3="ETG_C",A3="ETGC"),C3,"na") i would like to have something like this =IF(FIND(IF(OR(A2="ETG_C",A2="ETGC"),C2,"na"),K:K,1)," ",IF(OR(A2="ETG_C",A2="ETGC"),C2,"na")) another words, if the top value exists already, then add a blank space

• Fullscreen HTML Element using window.innerHeight/Width different with DOCTYPE

  - by CryptoQuick

  I'm trying to make an HTML5 canvas element fullscreen with the window.innerHeight and innerWidth properties. Unfortunately, on Chrome 10, when I set use the following doctype: <!DOCTYPE HTML> ...there is some extra scrolling space indicated by scroll bars which shouldn't appear. Without a doctype, everything is fine. The element is an HTML5 canvas, so styling with 100% will only stretch the content. Is it worth using a doctype which breaks my functionality (without which might be bad?), or should I subtract, say, 15px from the values in order to keep scroll bars from appearing? (which is kludgy)

• Android - How to tell is someone has pressed a SPINNER but not changed the visible item in it.

  - by andy_spoo

  I have a spinner, which mostly works. If a user selects one of the items in it, the 'onItemSelected' routine catches it just fine. But if a user clicks the same spinner, but does not change from the already visible item that it's currently displaying, the 'onItemSelected' routine just ignores it, and the logs show:- WARN/InputManagerService(577): Window already focused, ignoring focus gain of: com.android.internal.view.IInputMethodClient$Stub$Proxy@437948b0 I there anyway to capture someone doing this? The idea is that my spinner contains a list of names, and when a user selects one from the spinner, it gets added to a listview. I could just add another button to get the name from the spinner, but, screen-space is already lacking and I'd rather not add anymore content.

• Windows API calls from assembly while minimizing program size

  - by takteek

  I'm trying to write a program in assembly and make the resulting executable as small as possible. Some of what I'm doing requires windows API calls to functions such as WriteProcessMemory. I've had some success with calling these functions, but after compiling and linking, my program comes out in the range of 14-15 KB. (From a source of less than 1 KB) I was hoping for much, much less than that. I'm very new to doing low level things like this so I don't really know what would need to be done to make the program smaller. I understand that the exe format itself takes up quite a bit of space. Can anything be done to minimize that? I should mention that I'm using NASM and GCC but I can easily change if that would help.

• Display Computer Info on C# Web Application

  - by Gene

  I want to build a page for end users to visit (in our MPLS Network) and it show the following information in regards to them: Computer Name OS Disk Space Memory IP Address Active Directory User Name Password Expiration Time (As defined by Global Policy) Maybe a few other things such as Trend Micro Office current version vs. their version, # of MS Updates needed (we utilize WSUS), and a few other things in the future. My question is how would I pull this information from the user when they visit the page? What is the proper function for this? Anyone have examples they wish to share for me to learn by if possible? Thanks so much in advance, Gene

• possible bug in geom_ribbon

  - by tomw

  i was hoping to plot two time series and shade the space between the series according to which series is larger at that time. here are the two series-- first in a data frame with an indicator for whichever series is larger at that time d1 <- read.csv("https://dl.dropbox.com/s/0txm3f70msd3nm6/ribbon%20data.csv?dl=1") And this is the melted series. d2 <- read.csv("https://dl.dropbox.com/s/6ohwmtkhpsutpig/melted%20ribbon%20data.csv?dl=1") which I plot... ggplot() + geom_line(data = d2, aes(x = time, y = value, group = variable, color = variable)) + geom_hline(yintercept = 0, linetype = 2) + geom_ribbon(data = d1[d1$big == "B",], aes(x = time, ymin = csa, ymax = csb), alpha = .25, fill = "#9999CC") + geom_ribbon(data = d1[d1$big == "A",], aes(x = time, ymin = csb, ymax = csa), alpha = .25, fill = "#CC6666") + scale_color_manual(values = c("#CC6666" , "#9999CC")) which results in... why is there a superfluous blue band in the middle of the plot?

• multidimensional vector rotation and angle computation -- how?

  - by macias

  Input: two multidimensional (for example dim=8) vectors a and b. I need to find out the "directed" angle (0-2*Pi, not 0-Pi) between those vectors a and b. And if they are not parallel I need to rotate vector b in plane a,b by "directed" angle L. If they are parallel, plane does not matter, but angle of rotation is still the same L. For 2d and 3d this is quite easy, but for more dimensions I am lost, I didn't find anything on google, and I prefer using some already proved&tested equations (avoiding errors introduced by my calculations :-D). Thank you in advance for tips, links, etc. Edit: dimension of the space is the same as dimension of the vectors.

• Replace underscore between words (reg.exp)

  - by lasseespeholt

  Hey, I need a regular expression to solve the following problem (links to similar problems is also appreciated, related tutorials etc.): __some_words_a_b___ => __some words a b___ ____ => ____ So I want underscores between words to be replaced with space and keep leading and trailing underscores. I found this: ^[ \t]+|[ \t]+$ and I guess it most be something like that. I will use it in jQuery, Java (stdlibs) and maybe XSLT. Addition: The sentences do not necessarily start with underscores or ends with underscores. It is also possible that a sentence ain't containing underscores at all. Best regards Lasse Espeholt

• In Delphi, Is there a way to adjust the line spacing of a TMemo?

  - by Kieran

  I'm working with a TMemo component to display some text in a limited space. Currently it's using a truetype font which doesn't ship with windows and is installed by the app when it runs. On my PC (Running Windows XP), the spacing between each line of text seems to be about eight pixels. On a different PC running Windows 7, the line spacing seems to be about 14 pixels, which is pushing the bottom row of text out of visibility on the memo. So, My question is really this: Is this caused by the different versions of Windows? It's all I could think that was different. Is there some way I can adjust this value so it would be consistent across all instances of the application, wherever it was running? Alternatatively, is there a different component I could use which might let me tweak this value?

• Program seems to get stuck ?

  - by Frank

  I have a Java program, I did some change and the strange thing is no matter what I do now, it will output the same result before my change, I looked into my system (Windows Vista), and clicked on "Generate a system health report", the result says : Symptom : A service is reported as having an unexpected error code Cause : One or more services has failed. The service did not stop gracefully, suggesting the service may have crashed or one of its components stopped in an unsupported way. Details : Service exited with code not equal to 0 or 1077 Resolution : Restart the service It doesn't say which service, and I defragmented my drives a few times, it still gave me the same report. I also checked my memory, it says no problem with ram. Everything else is ok, I re-started the windows a few times, got more free space on my C: drive, yet the Java program is still not responding to my new changes, unless I intentionally make a mistake, it gives me compile error, but if it can compile successfully, it still gives me the results before the change. What can I do to fix this ? Frank

• Java Convert ColorSpace of BufferedImage to CS_GRAY without using ConvertColorOp

  - by gmatt

  I know its possible to convert an image to CS_GRAY using public static BufferedImage getGrayBufferedImage(BufferedImage image) { BufferedImageOp op = new ColorConvertOp(ColorSpace .getInstance(ColorSpace.CS_GRAY), null); BufferedImage sourceImgGray = op.filter(image, null); return sourceImgGray; } however, this is a chokepoint of my entire program. I need to do this often, on 800x600 pixel images and takes about 200-300ms for this operation to complete, on average. I know I can do this alot faster by using one for loop to loop through the image data and set it right away. The code above on the other hand constructs a brand new 800x600 BufferedImage that is gray scale. I would rather just transform the image I pass in. Does any one know how to do this with a for loop and given that the image is RGB color space?

• What regular expression do I need to check for some non-latin characters?

  - by zeckdude

  I am checking a field if it is Latin Characters or not. var foreignCharacters = $("#foreign_characters").val(); var rlatins = /[\u0000-\u007f]/; if (rlatins.test(foreignCharacters)) { alert("This is Latin Characters"); } else { alert("This is non-latin Characters"); } This works well, but I would like to change it so when I enter any non-latin characters, such as chinese characters, along with a space(which is within that range I am using currently) it will still say it is non-latin characters. How can I change the regular expression I have to do that?

• Multiple Questions per page using Drupal Quiz

  - by Andrew

  I'm using the Drupal Quiz module, and have setup some basic quizzes and stuff like that. However some further customization is required, involving more than 1 question per page, and a multi-type answer in this type of format: Question 1: Describe 4 things you did last summer a) [ short answer space - text field ] b) "I wept" c) "My whole family died so I learned self reliance" d) "I got another xbox" Question 2: Describe 2 things you hate about yourself a) "My arms are way shorter than my legs" b) "I was born without human emotion" So I guess in two parts, how to show multiple questions per page, and then how to allow multiple text fields for answers. Oh and this quiz is not graded, it's like a self assessment. Thanks!

• matplotlib.pyplot, preserve aspect ratio of the plot

  - by Headcrab

  Assuming we have a polygon coordinates as polygon = [(x1, y1), (x2, y2), ...], the following code displays the polygon: import matplotlib.pyplot as plt plt.fill(*zip(*polygon)) plt.show() By default it is trying to adjust the aspect ratio so that the polygon (or whatever other diagram) fits inside the window, and automatically changing it so that it fits even after resizing. Which is great in many cases, except when you are trying to estimate visually if the image is distorted. How to fix the aspect ratio to be strictly 1:1? (Not sure if "aspect ratio" is the right term here, so in case it is not - I need both X and Y axes to have 1:1 scale, so that (0, 1) on both X and Y takes an exact same amount of screen space. And I need to keep it 1:1 no matter how I resize the window.)

• A specific string format with a number and character together represeting a certain item

  - by sil3nt

  Hello there, I have a string which looks like this "a 3e,6s,1d,3g,22r,7c 3g,5r,9c 19.3", how do I go through it and extract the integers and assign them to its corresponding letter variable?. (i have integer variables d,r,e,g,s and c). The first letter in the string represents a function, "3e,6s,1d,3g,22r,7c" and "3g,5r,9c" are two separate containers . And the last decimal value represents a number which needs to be broken down into those variable numbers. my problem is extracting those integers with the letters after it and assigning them into there corresponding letter. and any number with a negative sign or a space in between the number and the letter is invalid. How on earth do i do this?

• How can I make my search more broad?

  - by user1804952

  I created this search mysql string and it is to literal or maybe un-literal? If I search for Dave for example it will only find items like "Dave something" and not find Dave. $queryArtist = mysql_query("SELECT * FROM artists WHERE artist LIKE '%$ArtistNameSearch%' ORDER BY artist ASC"); I know mysql_query is out dated and will change it to mysqli soon as I get this worked out. Stuck here. An example of it no working is Example of search Could it be becasue the %20 space? I got it figured out, but it still does NOT find one direction or other things even those exist. here is what I have now $queryArtist = mysql_query("SELECT * FROM artists WHERE match(artist) against('$SafeSearchTerm' in boolean mode)");

• Blackberry - Custom size EditField

  - by Eric

  I am trying to put together a dialog that should look like this: Fill in the below fields ___________ likes ________________ where the "_" lines are the EditFields. I am sticking all the fields in a HorizontalFieldManager, which I add to the dialog. Unfortunately, the first EditField consumes all the space on the first line. I have tried to override the getPreferredWidth() method of the EditField by creating my own class extending BasicEditField, but have had no success. Surely there must be a simple way to force a certain size for an edit field. What am I missing?

• Using install_name_tool what's going wrong?

  - by 0x80

  I'm trying to change the install path of a dylib after it has been build. I use "otool -L" to check what the current path is. And then I do: $ install_name_tool -change /my/current/path/libmine.dylib /my/new/path/libmine.dylib libmine.dylib I don't get an error, but nothing changes. If I check the path again the old one is still there. Also the new path is a lot shorter then the old one, so no problem there, and I think the lib is even compiled with extra flag for more filepath space. Any ideas?

• How to remove the title bar from a JFrame screenshot?

  - by Greg Harman

  I'm capturing a screenshot image of a JFrame via a "double buffering" approach, per below: public BufferedImage getScreenshot() { java.awt.Dimension dim = this.getPreferredSize(); BufferedImage image = new BufferedImage(dim.width, dim.height, BufferedImage.TYPE_INT_RGB); this.paint(image.getGraphics()); return image; } where this extends JFrame. The image that I get has a blank strip along the top where the title bar was. What's the most straightforward way to capture an image of the contents of the JFrame without the extra space allocated for the title bar?

• Storing n-grams in database in < n number of tables.

  - by kurige

  If I was writing a piece of software that attempted to predict what word a user was going to type next using the two previous words the user had typed, I would create two tables. Like so: == 1-gram table == Token | NextWord | Frequency ------+----------+----------- "I" | "like" | 15 "I" | "hate" | 20 == 2-gram table == Token | NextWord | Frequency ---------+------------+----------- "I like" | "apples" | 8 "I like" | "tomatoes" | 12 "I hate" | "tomatoes" | 20 "I hate" | "apples" | 2 Following this example implimentation the user types "I" and the software, using the above database, predicts that the next word the user is going to type is "hate". If the user does type "hate" then the software will then predict that the next word the user is going to type is "tomatoes". However, this implimentation would require a table for each additional n-gram that I choose to take into account. If I decided that I wanted to take the 5 or 6 preceding words into account when predicting the next word, then I would need 5-6 tables, and an exponentially increase in space per n-gram. What would be the best way to represent this in only one or two tables, that has no upper-limit on the number of n-grams I can support?
