• NullPointerException in NetBeans 6.5 IDE itself

  - by titaniumdecoy

  When I use NetBeans for almost any task (in particular, attempting to open a project), a red minus sign in the bottom right corner of the IDE starts blinking and I get the following NullPointerException error when I click it. Unfortunately I cannot reinstall NetBeans since I am using a shared computer lab account. java.lang.NullPointerException at org.openide.util.Exceptions.attachMessage(Unknown Source) at org.netbeans.modules.project.ant.Util$ErrHandler.annotate(Unknown Source) at org.netbeans.modules.project.ant.Util$ErrHandler.fatalError(Unknown Source) at com.sun.org.apache.xerces.internal.util.ErrorHandlerWrapper.fatalError(ErrorHandlerWrapper.java:177) at com.sun.org.apache.xerces.internal.impl.XMLErrorReporter.reportError(XMLErrorReporter.java:388) at com.sun.org.apache.xerces.internal.impl.XMLScanner.reportFatalError(XMLScanner.java:1414) at com.sun.org.apache.xerces.internal.impl.XMLDocumentScannerImpl$PrologDriver.next(XMLDocumentScannerImpl.java:925) at com.sun.org.apache.xerces.internal.impl.XMLDocumentScannerImpl.next(XMLDocumentScannerImpl.java:648) at com.sun.org.apache.xerces.internal.impl.XMLNSDocumentScannerImpl.next(XMLNSDocumentScannerImpl.java:140) at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl.scanDocument(XMLDocumentFragmentScannerImpl.java:510) at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(XML11Configuration.java:807) at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(XML11Configuration.java:737) at com.sun.org.apache.xerces.internal.parsers.XMLParser.parse(XMLParser.java:107) at com.sun.org.apache.xerces.internal.parsers.DOMParser.parse(DOMParser.java:225) at com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderImpl.parse(DocumentBuilderImpl.java:283) at org.openide.xml.XMLUtil.parse(Unknown Source) at org.netbeans.modules.project.ant.AntBasedProjectFactorySingleton.loadProjectXml(Unknown Source) at org.netbeans.modules.project.ant.AntBasedProjectFactorySingleton.loadProject(Unknown Source) at org.netbeans.api.project.ProjectManager.createProject(Unknown Source) at org.netbeans.api.project.ProjectManager.access$300(Unknown Source) at org.netbeans.api.project.ProjectManager$2.run(Unknown Source) at org.netbeans.api.project.ProjectManager$2.run(Unknown Source) at org.openide.util.Mutex.readAccess(Unknown Source) at org.netbeans.api.project.ProjectManager.findProject(Unknown Source) at org.netbeans.modules.project.ui.OpenProjectList.fileToProject(Unknown Source) at org.netbeans.modules.project.ui.ProjectChooserAccessory$ProjectFileView.run(Unknown Source) at org.openide.util.RequestProcessor$Task.run(Unknown Source) [catch] at org.openide.util.RequestProcessor$Processor.run(Unknown Source) I have recently had problems with going over my disk space quota on this computer lab account.

• Can a C# method chain be "too long"?

  - by ccornet

  Not in terms of readability, naturally, since you can always arrange the separate methods into separate lines. Rather, is it dangerous, for any reason, to chain an excessively large number of methods together? I use method chaining primarily to save space on declaring individual one-use variables, and traditionally using return methods instead of methods that modify the caller. Except for string methods, those I kinda chain mercilessly. In any case, I worry sometimes about the impact of using exceptionally long method chains all in one line. Let's say I need to update the value of one item based on someone's username. Unfortunately, the shortest method to retrieve the correct user looks something like the following. SPWeb web = GetWorkflowWeb(); SPList list2 = web.Lists["Wars"]; SPListItem item2 = list2.GetItemById(3); SPListItem item3 = item2.GetItemFromLookup("Armies", "Allied Army"); SPUser user2 = item2.GetSPUser("Commander"); SPUser user3 = user2.GetAssociate("Spouse"); string username2 = user3.Name; item1["Contact"] = username2; Everything with a 2 or 3 lasts for only one call, so I might condense it as the following (which also lets me get rid of a would-be-superfluous 1): SPWeb web = GetWorkflowWeb(); item["Contact"] = web.Lists["Armies"] .GetItemById(3) .GetItemFromLookup("Armies", "Allied Army") .GetSPUser("Commander") .GetAssociate("Spouse") .Name; Admittedly, it looks a lot longer when it is all in one line and when you have int.Parse(ddlArmy.SelectedValue.CutBefore(";#", false)) instead of 3. Nevertheless, this is one of the average lengths of these chains, and I can easily foresee some of exceptionally longer counts. Excluding readability, is there anything I should be worried about for these 10+ method chains? Or is there no harm in using really really long method chains?

• confusing fork system call

  - by benjamin button

  Hi, i was just checking the behaviour of fork system call and i found it very confusing. i saw in a website that Unix will make an exact copy of the parent's address space and give it to the child. Therefore, the parent and child processes have separate address spaces #include <stdio.h> #include <sys/types.h> int main(void) { pid_t pid; char y='Y'; char *ptr; ptr=&y; pid = fork(); if (pid == 0) { y='Z'; printf(" *** Child process ***\n"); printf(" Address is %p\n",ptr); printf(" char value is %c\n",y); sleep(5); } else { sleep(5); printf("\n ***parent process ***\n",&y); printf(" Address is %p\n",ptr); printf(" char value is %c\n",y); } } the output of the above program is : *** Child process *** Address is 69002894 char value is Z ***parent process *** Address is 69002894 char value is Y so from the above mentioned statement it seems that child and parent have separet address spaces.this is the reason why char value is printed separately and why am i seeing the address of the variable as same in both child and parent processes.? Please help me understand this!

• Stretch Background Image & Resize With Browser Window

  - by user241673

  I am trying to replicate the image resizing found at http://devkick.com/lab/fsgallery/ but with the code I have below, it is not working properly. When resizing the browser window to have small width and big height, white space shows up at the bottom of the page. feel free to see it & edit at http://jsbin.com/ifolu3 The CSS: html, body {width:100%; height:100%; overflow:hidden;} div.bg {position:absolute; width:200%; height:200%; top:-50%; left:-50%;} img.bg {min-height:50%; min-width:50%; margin:0 auto; display:block;} The JS/jQuery: $(window).resize(function(){ var ratio = Math.max($(window).width()/$('img.bg').width(),$(window).height()/$('img.bg').height()); if ($(window).width() $(window).height()) { $('img.bg').css({width:image.width()*ratio,height:'auto'}); } else { $('img.bg').css({width:'auto',height:image.height()*ratio}); } }); The HTML - (sorry for the formatting, had trouble getting "<" to show) [body] [div class="bg"] [img class="bg" src="bg.jpg" /] [/div] [/body]

• [Cocoa] Core Animation with an NSView and subviews

  - by ndg

  I've subclassed NSView to create a 'container' view (which I've called TRTransitionView) which is being used to house two subviews. At the click of a button, I want to transition one subview out of the parent view and transition the other in, using the Core Animation transition type: kCATransitionPush. For the most part, I have this working as you'd expect (here's a basic test project I threw together). The issue I'm seeing relates to resizing my window and then toggling between my two views. After resizing a window, my subviews will appear at seemingly random locations within my TRTransitionView. Additionally, it appears as if the TRTransitionView hasn't stretched correctly and is clipping the contents of its subviews. Ideally, I would like subviews anchored to the top-left of their parent view at all times, and to also grow to expand the size of the parent view. The second issue relates to an NSTableView I've placed in my first subview. When my window is resized, and my TRTransitionView resizes to match its new dimensions, my TableView seems to resize its content quite awkwardly (the entire table seems to jolt around) and the newly expanded space that the table now occupies seems to 'flash' (as if in the process of being animated). Extremely difficult to describe, but is there any way to stop this? Here's my TRTransitionView class: -(void) awakeFromNib { [self setWantsLayer:YES]; [self addSubview:[self currentView]]; transition = [CATransition animation]; [transition setType:kCATransitionPush]; [transition setSubtype:kCATransitionFromLeft]; [self setAnimations: [NSDictionary dictionaryWithObject:transition forKey:@"subviews"]]; } - (void)setCurrentView:(NSView*)newView { if (!currentView) { currentView = newView; return; } [[self animator] replaceSubview:currentView with:newView]; currentView = newView; } -(IBAction) switchToViewOne:(id)sender { [transition setSubtype:kCATransitionFromLeft]; [self setCurrentView:viewOne]; } -(IBAction) switchToViewTwo:(id)sender { [transition setSubtype:kCATransitionFromRight]; [self setCurrentView:viewTwo]; }

• div stacking/layout with css or javascript

  - by liz

  so i have 4 divs (i actually have many more but this will simplify the question). i want to display them in two columns. the 4 divs vary in height. the number of actual divs in the end will vary. so if i have this <div id="1" style="height: 200px" class="inline">some content here</div> <div id="2" style="height: 600px" class="inline">some content here</div> <div id="3" style="height: 300px" class="inline">some content here</div> <div id="4" style="height: 200px" class="inline">some content here</div> with styling thus .inline { display: inline-block; vertical-align: top; width: 48%;} so #1 would go left and then #2 would shove up beside it to the right, great, but the #3 will not slide up the 400px to fit nicely below #1. (of course)... it goes on the left side but at 600px from the top clearing the bottom of #2. etc... how would i get the divs to slide up into the empty spaces, is it possible with css? jquery maybe? i know i could write column divs to mark it up, but since the number of divs constantly change and the heights vary according to content. It would be nice to just get rid of the space since we dont really care about the order. any thoughts?

• Bilinear interpolation - DirectX vs. GDI+

  - by holtavolt

  I have a C# app for which I've written GDI+ code that uses Bitmap/TextureBrush rendering to present 2D images, which can have various image processing functions applied. This code is a new path in an application that mimics existing DX9 code, and they share a common library to perform all vector and matrix (e.g. ViewToWorld/WorldToView) operations. My test bed consists of DX9 output images that I compare against the output of the new GDI+ code. A simple test case that renders to a viewport that matches the Bitmap dimensions (i.e. no zoom or pan) does match pixel-perfect (no binary diff) - but as soon as the image is zoomed up (magnified), I get very minor differences in 5-10% of the pixels. The magnitude of the difference is 1 (occasionally 2)/256. I suspect this is due to interpolation differences. Question: For a DX9 ortho projection (and identity world space), with a camera perpendicular and centered on a textured quad, is it reasonable to expect DirectX.Direct3D.TextureFilter.Linear to generate identical output to a GDI+ TextureBrush filled rectangle/polygon when using the System.Drawing.Drawing2D.InterpolationMode.Bilinear setting? For this (magnification) case, the DX9 code is using this (MinFilter,MipFilter set similarly): Device.SetSamplerState(0, SamplerStageStates.MagFilter, (int)TextureFilter.Linear); and the GDI+ path is using: g.InterpolationMode = InterpolationMode.Bilinear; I thought that "Bilinear Interpolation" was a fairly specific filter definition, but then I noticed that there is another option in GDI+ for "HighQualityBilinear" (which I've tried, with no difference - which makes sense given the description of "added prefiltering for shrinking") Followup Question: Is it reasonable to expect pixel-perfect output matching between DirectX and GDI+ (assuming all external coordinates passed in are equal)? If not, why not? Finally, there are a number of other APIs I could be using (Direct2D, WPF, GDI, etc.) - and this question generally applies to comparing the output of "equivalent" bilinear interpolated output images across any two of these. Thanks!

• Suggested (simple) approach for drawing large numbers of visual elements in WPF?

  - by Ender

  I'm writing an interface that features a large (~50000px width) "canvas"-type area that is used to display a lot of data in a fairly novel way. This involves lots of lines, rectangles, and text. The user can scroll around to explore the entire canvas. At the moment I'm just using a standard Canvas panel with various Shapes placed on it. This is nice and easy to do: construct a shape, assign some coordinates, and attach it to the Canvas. Unfortunately, it's pretty slow (to construct the children, not to do the actual rendering). I've looked into some alternatives, it's a bit intimidating. I don't need anything fancy - just the ability to efficiently construct and place objects in a coordinate plane. If all I get are lines, colored rectangles, and text, I'll be happy. Do I need Geometry instances inside of Geometry Groups inside of GeometryDrawings inside of some Panel container? Note: I'd like to include text and graphics (i.e. colored rectangles) in the same space, if possible.

• Is this a variation of the traveling salesman problem?

  - by Ville Koskinen

  I'm interested in a function of two word lists, which would return an order agnostic edit distance between them. That is, the arguments would be two lists of (let's say space delimited) words and return value would be the minimum sum of the edit (or Levenshtein) distances of the words in the lists. Distance between "cat rat bat" and "rat bat cat" would be 0. Distance between "cat rat bat" and "fat had bad" would be the same as distance between "rat bat cat" and "had fat bad", 4. In the case the number of words in the lists are not the same, the shorter list would be padded with 0-length words. My intuition (which hasn't been nurtured with computer science classes) does not find any other solution than to use brute force: |had|fat|bad| a solution ---+---+---+---+ +---+---+---+ cat| 2 | 1 | 2 | | | 1 | | ---+---+---+---+ +---+---+---+ rat| 2 | 1 | 2 | | 3 | | | ---+---+---+---+ +---+---+---+ bat| 2 | 1 | 1 | | | | 4 | ---+---+---+---+ +---+---+---+ Starting from the first row, pick a column and go to the next rows without ever revisiting a column you have already visited. Do this over and over again until you've tried all combinations. To me this sounds a bit like the traveling salesman problem. Is it, and how would you solve my particular problem?

• Java Random Slowdowns on Mac OS cont'd

  - by javajustice

  I asked this question a few weeks ago, but I'm still having the problem and I have some new hints. The original question is here: http://stackoverflow.com/questions/1651887/java-random-slowdowns-on-mac-os Basically, I have a java application that splits a job into independent pieces and runs them in separate threads. The threads have no synchronization or shared memory items. The only resources they do share are data files on the hard disk, with each thread having an open file channel. Most of the time it runs very fast, but occasionally it will run very slow for no apparent reason. If I attach a CPU profiler to it, then it will start running quickly again. If I take a CPU snapshot, it says its spending most of its time in "self time" in a function that doesn't do anything except check a few (unshared unsynchronized) booleans. I don't know how this could be accurate because 1, it makes no sense, and 2, attaching the profiler seems to knock the threads out of whatever mode they're in and fix the problem. Also, regardless of whether it runs fast or slow, it always finishes and gives the same output, and it never dips in total cpu usage (in this case ~1500%), implying that the threads aren't getting blocked. I have tried different garbage collectors, different sizings the parts of the memory space, writing data output to non-raid drives, and putting all data output in threads separate the main worker threads. Does anyone have any idea what kind of problem this could be? Could it be the operating system (OS X 10.6.2) ? I have not been able to duplicate it on a windows machine, but I don't have one with a similar hardware configuration.

• How does one create and use a pointer to an array of an unknown number of structures inside a class?

  - by user1658731

  Sorry for the confusing title... I've been playing around with C++, working on a project to parse a game's (Kerbal Space Program) save file so I can modify it and eventually send it over a network. I'm stuck with storing an unknown number of vessels and crew members, so I need to have an array of unknown size. Is this possible? I figured having a pointer to an array would be the way to go. I have: class SaveFileSystem { string version; string UT; int activeVessel; int numCrew; ??? Crews; // !! int numVessels; ??? Vessels; // !! } Where Crews and Vessels should be arrays of structures: struct Crew { string name; //Other stuff }; struct Vessel { string name; //Stuff }; I'm guessing I should have something like: this->Crews = new ???; this->Vessels = new ???; in my constructor to initialize the arrays, and attempt to access it with: this->Crews[0].name = "Ship Number One"; Does this make any sense??? I'd expect the "???"'s to involve a mess of asterisk's, like "*struct (*)Crews" but I have no real idea. I've got normal pointers down and such, but this is a tad over my head... I'd like to access the structures like in the last snippet, but if C++ doesn't like that I could do pointer arithmetic. I've looked into vectors, but I have an unhealthy obsession with efficiency, and it really pains me how you don't know what's going on behind it.

• Is there a way to easily convert a series of tarballs of a source tree into a git repository?

  - by Hotei

  I'm new to git and I have a moderately large number of weekly tarballs from a long running project. Each tarball has on average a few hundred files in it. I'm looking for a git strategy that will allow me to add the expanded contents of each tarball to a new git repository, starting from version 1.001 and going through version 1.650. As of this stage of the project 99.5% of tarball(n) is just a copy of version(n-1) - in other words, a perfect candidate for git. The desired end result is to have only the master branch remaining at the end of the process. I think I know git well enough to do this "by hand". As I understand it there is no possibility of a merge conflict since there will be no opportunity to change the master before the next version is added and committed. A shell script is my first guess, but I'm not sure how well bash will like it when git checkout branch_n gets processed while bash is executing in branch_n-1. For the purposes of this project the host environment is Ubuntu 10.4, resources available are 8 Gig RAM, 500 Gig Disk space free and 4 CPU processor at 3.ghz . I don't need someone else to solve the problem but I could use a nudge in the right direction as to how a git expert would approach it. Any advice from someone who's "been there done that" would be appreciated. Hotei PS: I have looked at site's suggested "related questions" and found nothing relevant.

• CSS: div text wrap around floated div

  - by Thildemar

  I am trying to create a site that has a fixed width content div and a floating div in the blank space on the right of the page, like so: <html> <div style="width:150px;float:right;border:thin black solid"> Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat. Ut wisi enim ad minim veniam.</div> <div style="width:400px"> Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat. Ut wisi enim ad minim veniam, quis nostrud exerci tation ullamcorper suscipit lobortis nisl ut aliquip ex ea commodo consequat. Duis autem vel eum iriure dolor in hendrerit in vulputate velit esse molestie consequat, vel illum dolore eu feugiat nulla facilisis at vero eros et accumsan et iusto odio dignissim qui blandit praesent luptatum zzril delenit augue duis dolore te feugait nulla facilisi. </div> </html> This works fine, but when the page is re sized too small either the left div jumps down or the text within it does not start wrapping around the right div until its about halfway through it. I would like the test within the left div to wrap around the float is the page width is too small. What am I missing??

• Multiple calls to preg_replace alters result

  - by Hurpe

  I have a bunch of files that were named in a somewhat standard format. The standard form is basically this: [integer]_word1_word2_word3_ ... _wordn where a word could really be anything, but all words are separated by an underscore. There is really only 3 things I want to do to the text: 1.) I want to modify the integer, which is always at the beginning, so that something like "200" would become $ 200.00. 2.) replace any "words" of the form "with", "With", "w/", or "W/" with "with". 3.) Replace all underscores with a space. I wrote three different preg_replace calls to do the trick. They are as follows: 1.) $filename = preg_replace("/(^[0-9]+)/","$ $1.00",$filename) 2.) $filename = preg_replace("/_([wW]|[wW]ith)_/"," with ",$filename) 3.) $filename = preg_replace("/_/"," ",$filename); Each replacement works as expected when run individually, but when all three are run, the 2nd replacement is ignored. Why would something like that occur? Thanks for the help!

• Pointer initialization

  - by SoulBeaver

  Sorry if this question has been asked before. On my search through SO I didn't find one that asked what I wanted to know. Basically, when I have this: typedef struct node { int data; node *node; } *head; and do node *newItem = new node; I am under the impression that I am declaring and reserving space, but not defining, a pointer to struct node, is that correct? So when I do newItem->data = 100 and newItem->next = 0 I get confused. newItem = 0would declare what exactly? Both data and next? The object as a whole? I'm especially confused when I use typedef. Which part is the macro? I assume node because that's how I call it, but why do I need it? Finally, what happens when I do: node *temp; temp = new node; temp = head->next; head->next = newItem; newItem->next = temp; I mean, head-next is a pointer pointing to object newItem, so I assume not to newItem.data or next themselves. So how can I use an uninitialized pointer that I described above safely like here? is head now not pointing to an uninitialized pointer?

• prevent escaping special characters on textnode(JS-HTML)

• Search and highlight html - ignoring and maintaining tags

  - by Sleepwalker

  I am looking for a good way to highlight key words in a block of html with stripping the html tags. I can regex to search for key words within html tags, but I haven't found a great way to search across tags. For example, if the key word phrase is "not bound" I want to be able to make this <p>I am not<strong>bound to please thee</strong> with my answers.</p> become wrapped in highlight tags, without breaking the "strong" tag (and making the html invalid) and become: <p>I am <span class="highlight">not</span><strong><span class="highlight">bound</span> to please thee</strong> with my answers.</p> The main issue is maintaining the html as it is AND wrapping blocks of text with highlight tags. I need to maintain the original html. Otherwise I would strip the tags. The best solution to this that I can think of right now would entail making a copy of the html and placing counter tokens where each space occurs, then stripping all tags and search for matching phrases, then looking back to the original and the tokenized strings and figuring out where to start building the highlight tags, then start walking forward, starting and ending highlight spans as needed from the beginning of the match until the end. This seems like overkill. I would like to something more elegant if possible. The solution would be written in C# or perhaps javascript, depending.

• How can you make the copyright text in a Google Map wrap when the map is small?

  - by Paul D. Waite

  When you embed a Google Map on a web page, copyright text is included on the map. This is the HTML: <div style="border-top: 10px solid rgb(204, 0, 0); -moz-user-select: none; z-index: 0; position: absolute; right: 3px; bottom: 2px; color: black; font-family: Arial,sans-serif; font-size: 11px; white-space: normal; text-align: right; margin-left: 70px; width: 210px;" dir="ltr"> <span></span> <span>Map data &copy;2010 LeadDog Consulting, Europa Technologies - </span> <a href="http://www.google.com/intl/en_ALL/help/terms_maps.html" target="_blank" class="gmnoprint terms-of-use-link" style="color: rgb(119, 119, 204);">Terms of Use</a> <span></span> </div> If you embed a map with a small width, the copyright text extends outside of the <div>, instead of wrapping within it. I’ve tried using jQuery to select this HTML based on its contents (using :contains()), but it doesn’t seem to work in IE 8 (which is odd, as it works fine in IE 7). Any idea what’s up with IE 8? Any other methods to achieve the same result?

• Loading Jscript files into Firefox extension

  - by colon3l

  Hi ! Let's get directly to the problem : I'm actually doing a firefox extension in which i would like to implement the jWebsocket API in order to build a small chat. I got my main script file, named test.js, and the jWebsocket lib into a js folder. Just for you to know, this is my first firefox extension ever. So in my XUL file I got this (for the script part only of course, the interface code is not shown) : <overlay id="test-overlay" xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"> <script type="application/x-javascript" src="chrome://test/content/test.js" /> <script type="application/x-javascript" src="chrome://test/content/js/jwebsocket.js" /> jwebsocket.js being the file I need to call according to jWebsocket website. In my main script file test.js I start with : if (jws.browserSupportsWebSockets()) { jWebSocketClient = new jws.jWebSocketJSONClient(); } else { var lMsg = jws.MSG_WS_NOT_SUPPORTED; alert(lMsg); } jws being the namespace created into the jwebsocket.js file. Of course I've got the required stand-alone server running in background, and working. So from what I understood looking on various websites, is that if a js file is loaded into the javascript allocated memory space (with the tag), all namespace/function should be available between each file. But this was mostly for HTML-oriented issues, so I'm not sure if it applies to XUL/Firefox environment. But the script keep failing at the first jws call. Any ideas on what goes wrong here ? I'm stuck for 2 days now :/

  Hi, I have the following HTML for buttons implementing sliding doors technique that look fine in everything but Safari on Windows: <button type="submit"> <span>Button</span> </button> This is the corresponding CSS: button { background:url("../images/sprBgBtn.png") no-repeat right -47px; border:0; cursor:pointer; font-weight:bold; height:27px; line-height:27px; overflow:visible; padding:0 26px 0 0; position:relative; text-align:center; text-transform:uppercase; width:auto; } button::-moz-focus-inner { border: none; /* overrides extra padding in Firefox */ padding:0; } button span { background:url("../images/sprBgBtn.png") no-repeat left top; display:block; height:27px; line-height:27px; padding:0 0 0 26px; position:relative; white-space:nowrap; } If i omit the following code then the same issue will appear in FFOX: button::-moz-focus-inner { border: none; /* overrides extra padding in Firefox */ padding:0; }

• ASP .NET confusion - server controls

  - by Brandi

  I have read through the information in this question: http://stackoverflow.com/questions/22084/asp-net-aspxxx-controls-versus-standard-html but am still rather confused. The situation was I was asked to do a web project where I made a wizard. When I was done with the project everyone asked why I had used an <asp:Wizard...>. I thought this was what was being asked for, but apparently not, so after this I was led to believe that server controls were just prototyping tools. However, the next project I did my DB queries through C# code-behind and loaded the results via html. I was then asked why I had not used a gridview and a dataset. Does anyone have a list of pros and cons why they would choose to use specific html controls over specific server controls and why? I guess I'm looking for a list... what server controls are okay to use and why? EDIT: I guess this question is open ended, so I'll clarify a few more specific questions... Is it okay to use very simple controls such as asp:Label or do these just end up wasting space? It seems like it would be difficult to access html in the code behind otherwise. Are there a few controls that should just never be used? Does anyone have a good resource that will show me pros and cons of each control?

• G++ Multi-platform memory leak detection tool

  - by indyK1ng

  Does anyone know where I can find a memory memory leak detection tool for C++ which can be either run in a command line or as an Eclipse plug-in in Windows and Linux. I would like it to be easy to use. Preferably one that doesn't overwrite new(), delete(), malloc() or free(). Something like GDB if its gonna be in the command line, but I don't remember that being used for detecting memory leaks. If there is a unit testing framework which does this automatically, that would be great. This question is similar to other questions (such as http://stackoverflow.com/questions/283726/memory-leak-detection-under-windows-for-gnu-c-c ) however I feel it is different because those ask for windows specific solutions or have solutions which I would rather avoid. I feel I am looking for something a bit more specific here. Suggestions don't have to fulfill all requirements, but as many as possible would be nice. Thanks. EDIT: Since this has come up, by "overwrite" I mean anything which requires me to #include a library or which otherwise changes how C++ compiles my code, if it does this at run time so that running the code in a different environment won't affect anything that would be great. Also, unfortunately, I don't have a Mac, so any suggestions for that are unhelpful, but thank you for trying. My desktop runs Windows (I have Linux installed but my dual monitors don't work with it) and I'd rather not run Linux in a VM, although that is certainly an option. My laptop runs Linux, so I can use that tool on there, although I would definitely prefer sticking to my desktop as the screen space is excellent for keeping all of the design documentation and requirements in view without having to move too much around on the desktop. NOTE: While I may try answers, I won't mark one as accepted until I have tried the suggestion and it is satisfactory. EDIT2: I'm not worried about the cross-platform compatibility of my code, it's a command line application using just the C++ libraries.

• [LaTeX] breaking an environment across pages - the smart way

  - by Flavius

  Hi I am using the exercise package to display exercises in a book. I have redefined some commands like this, which basically adds some space, a pencil, and two hrule's before and after the exercise: \renewcommand{\ExerciseHeader}{\vskip 1em\hrule\vskip 1em\centerline{\textbf{\large\smallpencil \ExerciseHeaderNB\ExerciseHeaderTitle% \ExerciseHeaderDifficulty\ExerciseHeaderOrigin\medskip}}} \makeatletter\def\endExerciseEnv{\termineliste{1}\@EndExeBox\vskip .5em\hrule\vskip 1em}\makeatother Now this works, but there's a small problem: There are situations where only the \hrule ends up being at the bottom of a page, and the rest of the exercise goes on the next page. There is also the opposite behavior: the entire exercise is on one page, except the \hrule in "endExerciseEnv", which is flushed to the next page. My question is: How to force the top hrule come either together with the header of the exercise (caption, title, whatever not) and at least the first two paragraphs (or \ExePath and a paragraph, or anything like that, but there must be at last "two things", so it doesn't look ugly), OR be flushed altogether, with the entire exercise? Similar question for the bottom hrule: How to force it have at least two items in front of it on the visible page where the hrule itself goes to? Any LaTeX guru who knows that? Addendum I have asked in the past LaTeX questions like this and I've got answers which required me to do stuff manually, like "insert a \vskip here and there" or such. Let me be clear: This is a book, there's lot of exercises, and I NEED it be done "automatically", by going the proper way of redeclaring commands & co.

• How do I sanitize a string in PHP that contains "; Echo"? (I have a solid reason)

  - by user337878

  I turned this case into a simple PHP page that submits to itself. My issue is that I am submitting track meet results and one of the girl's names is Echo...a lovely name. The problem text I'm submitting is: Pole vault - Rachel Simons, Tow, 8-6; Echo Wilson, Cit, 8-0; Molly Randall, Tow, 7-0; So you see a semicolon followed by white space followed by Echo... After submitting, it says: POST to /results/test.php not supported The end goal is to save it to a database along with some other info and have a search page to find it and simply print out the full result on the screen. I stripped out all my database stuff to get it down to this one error. I mean, I can intentionally mis-spell her name, but there's gotta be a way around this, right??? Here's the test PHP file. <html> <head> <title>title</title> </head> <body> <?php echo "<h3>Edit meet info below</h3>"; echo "<form action=\"test.php\" method=\"post\" id=\"submitForm\">"; echo "Full Results:<br/><textarea NAME=\"results\" id=\"results\" rows=\"20\" cols=\"80\" MAXLENGTH=\"8191\"></textarea><br/><br/>"; echo "<input type=\"submit\" name=\"submitMeet\" value=\"Submit\">"; echo "</form>"; ?> </body> </html>
