• How to change *.ico for button in running mode?

  - by karikari

  I am currently doing visual c++ for an Internet Explorer toolbar button. I have a registration script file (*.rgs) that defines or maybe register the features of my button inside the Windows registry. My objective is, I want my button to change its *.ico image, based on certain conditions process from my *.cpp file. My problem is, I don't understand, how can I somehow change the *.ico file for my button in real time, during my application is running? For example, IF f = 1, ico_file = green.ico; ELSE ico_file = red.ico; Any idea, that you guys can point to me, how can I change the *.ico file for my Internet Explorer toolbar button while the IE is running.

• CSS border and the :hover dynamic pseudo-class

  - by dbasch

  Hi All, I have built a persistent dropline menu with two levels using only CSS. It is pretty standard. It is a nested set of UL's and the UL's :hover state is what shows and hides the sub menu levels. Something like this: | *Pets* | Colors | Cars | | Cats | Dogs | Birds| Goats | Sheep | | Pets | *Colors* | Cars | | Red | Orange | Green | Blue| Yellow | I then added a 1px border at the bottom of the first level UL element. Like this: | *Pets* | Colors | Cars | -------------------------------------- | Cats | Dogs | Birds| Goats | Sheep | When I hover over a first level item (Pets), and then move the mouse down to the second level (Cats), the entire second level disappears. I finally figured out that the UL's 1px border is not included in the hover area for the UL. Can I add a border to the bottom of a dropline menu level without messing up the menu hovering? Thanks!

• Mathematica Plot3D does not produce a plot when graphing a user-defined function?

  - by pythonscript

  I'm writing a simple Mathematica implementation of the black-scholes model and using Plot3D to plot the pricing surface. However, when I run this code, no plot is produced. My call and put functions to produce correct values when run separately, but no plot is produced. Code: Clear[d1, d2, call, put, stockPrice, strikePrice, riskFreeRate, timeToExp, volatility] d1[stockPrice_, strikePrice_, riskFreeRate_, timeToExp_, volatility_] := (Log[stockPrice / strikePrice] + (riskFreeRate + 0.5*volatility^2)*timeToExp) / (volatility * Sqrt[timeToExp]) d2[stockPrice_, strikePrice_, riskFreeRate_, timeToExp_, volatility_] := d1[stockPrice, strikePrice, riskFreeRate, timeToExp, volatility] - volatility*Sqrt[timeToExp] call[stockPrice_, strikePrice_, riskFreeRate_, timeToExp_, volatility_] := stockPrice * CDF[NormalDistribution[0, 1], d1[stockPrice, strikePrice, riskFreeRate, timeToExp, volatility]] - strikePrice * Exp[-riskFreeRate*timeToExp] *CDF[NormalDistribution[0, 1], d2[stockPrice, strikePrice, riskFreeRate, timeToExp, volatility]] Plot3D[call[stockPrice, 500, 0.0030, timeToExp, 0.39], {stockPrice, 10, 1000}, {timetoExp, 0.0833333, 5}] Other plots, like this sample from the reference, do work. Plot3D[{x^2 + y^2, -x^2 - y^2}, {x, -2, 2}, {y, -2, 2}, RegionFunction -> Function[{x, y, z}, x^2 + y^2 <= 4], BoxRatios -> Automatic]

• Get all window handles for a process

  - by Jeremy

  Using Microsoft Spy++, I can see that the following windows that belong to a process: Process XYZ window handles, displayed in tree form just like Spy++ gives me: A B C D E F G H I J K I can get the process, and the MainWindowHandle property points to the handle for window F. If I enumerate the child windows using I can get a list of window handles for G through K, but I can't figure out how to find the window handles for A through D. How can I enumerate windows that are not children of the handle specified by MainWindowHandle of the Process object? To enumerate I'm using the win32 call: [System.Runtime.InteropServices.DllImport(strUSER32DLL)] public static extern int EnumChildWindows(IntPtr hWnd, WindowCallBack pEnumWindowCallback, int iLParam);

• Cleaning up nasty characters in PHP

  - by Simon Hume

  Hi folks, Got a little issue where my client is pasting in content from Word into my little text editor in a CMS. The double quotes are coming back encoded in what looks like some form of UTF.

Here is the link to the page that spits out the dodgy characters, you can see the 'black diamonds of doom' which are causing the headaches. http://linq.milkbarstudios.com/news_detail.php?id=3 Any suggestions would be greatly accepted!

• Qt not displaying PNG images on Linux

  - by ereOn

  Hi, I have a software written using Qt which is meant to work on both Windows and Linux. I use PNG images as icons for my QActions, embedded in a resource. I have the following tree directory: / resources/ icons.qrc image.png Here is the content of icons.qrc: <RCC> <qresource prefix="/resources" lang="fr"> <file alias="image.png">image.png</file> </qresource> </RCC> I declare my QIcon like that: QIcon(":/resources/image.png") Under Windows, it works well but on Linux (I only tried on Ubuntu 10.4 so far), the images aren't displayed. Is there anything special I have to do for this to work ? Is this a configuration problem ? Thank you.

• Dynamic Selectors with Jquery with php while loop

  - by Anders Kitson

  I have a while loop which creates a list of anchor tags each with a unique class name counting from 1 to however many items there are. I would like to change a css attriubute on a specific anchor tag and class when it is clicked so lets say the background color is changed. Here is my code while($row = mysql_fetch_array($results)){ $title = $row['title']; $i++; echo "<a class='$i'>$title</a> } I would like my jquery to look something like this, it is obviously going to be more complicated than this I am just confused as where to start. $(document).ready(function() { $('a .1 .2 .3 .4 and so on').click(function() { $('a ./*whichever class was clicked*/').css('background':'red'); }); });

• Gtk# TreeView set a single cell to have a different renderer?

  - by Buttink

  OK this is probably insane, but I want to be able to have a check box at the very top of every row in my tree view. This box will "disable" or "enable" the ability to use the column. Oh I think it should be mentioned that I'm using a ListStore and am using C#, mono, GTK#. However, ill take anything and try to figure it out. Ill even accept a way to make two views where the columns line up .... So, possible? or just insane?

• Virtual dedicated server repetitive draining RAM, OOM constantly

  - by Deerly

  My linux (fedora red hat 7) virtual dedicated server has been experiencing OOM multiple times a day for the past several days. I thought the issue was with spamd/spamassassin but after disabling this the errors remains. The highest usage displayed on ps faux --cumulative: USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 28412 8.7 0.5 309572 109308 ? Sl 22:15 0:17 /usr/java/jdk1. mysql 7716 0.0 0.0 136256 18000 ? Sl 22:12 0:00 _ /usr/libexe named 17697 0.0 0.0 120904 15316 ? Ssl 22:09 0:00 /usr/sbin/named I'm not running any java applications so I'm not sure why the top issue is showing up. It is frustrating as I barely have anything running on the server and use the tiniest fraction of bandwidth. Any help or suggestions on zeroing in on the source of the drain would be much appreciated! Thanks!

• Playing around with Eclipse features - Project files are now hidden?

  - by Daddy Warbox

  I don't even remember how, but somehow I managed to make all of my project's source files hidden in Eclipse's Package and Project Explorer panels. Go figure. 'Show Filtered Children (alt+click)' temporarily reveals the files, and only in Package Explorer can I double-click to reopen them from this view. They go back into hiding after I select another item, though. Plus, now I'm getting other annoyances, such as all of the folded non-hidden trees altogether expanding when I click on any item, and the entire file folder tree of my project now being shown in these panels (including my .svn subversion folders... which shouldn't be any of Eclipse's business, presently). Long story short, my Package/Project Explorers' just blew up on me, and I want to know how to fix this. Thanks in advance. P.S. What's a good guide I can use to learn my way around this silly contraption, anyway?

• Interface Builder "Simulate Interface" not working

  - by bpapa

  I am using Interface Builder to play around with some ideas. I never noticed that there is a "Simulate Interface" feature which apparently will render the nib in the iPhone simulator. So, I created a view, put one component in there (a Segmented Control), saved it, selected "Simulate Interface", the simulator launched but... nothing rendered in the simulator. Just a black screen. I thought maybe my nib wasn't complete enough, so I've tried it with all of my old nibs and I'm having the same problem with all of them. None of them render in the simulator at all. Is there some trick that I'm missing?

• In LaTeX prefer figures on text-heavy pages.

  - by bjarkef

  Hi LaTeX seems to have a preference for placing figures together on a page, and placing surrounding text on a separate page. Can I somehow change that balance a bit, as I prefer figures to break up the text to avoid too black text-heavy pages. Example: \section{Some section} [Half a page of text] \begin{figure} [...] \caption{Figure text 1} \end{figure} [Half a page of text] \begin{figure} [...] \caption{Figure text 2} \end{figure} [More text] So what LaTeX usually does is to stack the two half pages of text on a single page, and the figures on the following page. I believe this really gives a bad balance, and bores the reader. So can I change that somehow? I know about postfixing the \begin{figure} with [ht!], but often it does not really matter. I would like to configure the balancing algorithms in LaTeX to naturally prefer pages with combined figures and text.

• C# MDX RenderToSurface, where to reset after device is lost?

  - by Moritz Schöfl

  Hi, I got a problem with the RenderToSurface class. When I resize the Form of my Device, the Draw method is still called, but doesnt throw an Exception, it looks like this: device.Clear(ClearFlags.Target, Color.Red, 0, 0); device.BeginScene(); // here is out commented code device.EndScene(); device.Present(); In another method, I wrote this: renderToSurface.BeginScene(surfaces[currentIndex]); // here is out commented code renderToSurface.EndScene(Filter.None); and this method seems to throw a nullpointer exception when I resize the window; So my question is: - where to reset / restore / handle the renderToSurface class? (i tried it with the DeviceReset event like following - void OnDeviceReset(object sender, EventArgs e) { renderToSurface = new RenderToSurface(Game.Device, Game.ClientSize.Width, Game.ClientSize.Height, Format.A8R8G8B8, true, DepthFormat.D16); } )

• unable to get into windows 7 or ubuntu after system file back on a dual boot system

  - by John Jiang

  I installed ubuntu on my dell xps 9000 which originally has a window 7 installed. So after I did system file back up as told by windows 7 and restarted my computer, I received the following message right after restarting in the black screen: roughly like this: ubuntu grub error, " " symbol cannot be found. I was wondering how I can get access into windows 7 and uninstall ubuntu all together. I actually had the same booting problem after system backup before and the solution was to install two extra ubuntus but I'd prefer not to do that. I'd highly appreciate any help!

• Test whether image loaded correctly with JavaScript

  - by johkar

  I have an image deployed on several application servers (green up arrow: uparrow.gif). I have an application server status page where I list out all the servers and with a corresponding image where the image's source is the uparrow.gif for that server. If the image does not load (server down) I would like to switch to a red down arrow (downarrow.gif). Is there a way to check whether an image loaded or not with straight JavaScript (no JS libraries etc)? I would imagine I would set an interval for it to continue checking if the user were on the page. Thanks.

• Close button during modal sheet

  - by Nano8Blazex

  In Objective C (Cocoa) I have an app running with a modal sheet, but I want to allow the app to quit even when the sheet is displayed (contradicting the definition of modal I think, but I like the animated effect of modal sheets). I'm already using the -setPreventsApplicationTerminationWhenModal method and it works fine, but I'm wondering... is there any way to keep the close button enabled? The little circle usually red-colored close button that comes with all windows in the top left corner (side by side with minimize and maximize)? Right now it's completely disabled when the sheet is running, and it would be awesome if there is a way to enable it. Thanks!

• Imagemagick command line in PHP

  - by charly

  Hello everyone, I've got the following two commands for imagemagick in the command line: convert in.png container-mask.png +matte -compose CopyOpacity -composite out.png composite container.png out.png -compose multiply final.png Those two commands include 3 files: in.png: the file that should be masked container-mask.png: the back/white mask of the areas of container.png where in.png should be visible container.png image that includes the container for in.png, the one that has been masked in black/white with container-mask.png Now the question is how to transpose this commands into PHP calls. I've played around quite a bit, but I can't make sense of the API at http://php.net/manual/en/book.imagick.php Thanks and Bests, Charly

• How to use Firebug's debugger functions?

  - by TK

  I don't have an experience with any debugger in any language, but I recently found some videos showing Firebug. I'm now playing with Firebug with a script I included an error with. What I understand now is: I can set a breakpoint, which is shown as a red circle. Firebug stops at the breakpoint and gives me 4 options (Continue, Step Into, Step Over and Step Out). What I don't understand are: What is the difference between the 4 options (i.e., Continue, Step Into, Step Over and Step Out)? To me, Step Over is sometimes similar to Step Into... I could be wrong here. I would be grateful if you could explain the differences of the 4 options.

• Maven eclipse does not add a dependency

  - by Calm Storm

  I have the following snippet in my pom.xml <dependency> <groupId>aspectj</groupId> <artifactId>aspectjrt</artifactId> <version>1.5.3</version> </dependency> and in one of my Java files I refer a class org.aspectj.lang.ProceedingJoinPoint. When I do a "mvn clean install" it compiles and builds fine but when I do an eclipse:eclipse, and import the project in eclipse it gives me an error The import org.aspectj cannot be resolved. I checked the .classpath file that was generated and it does not have an entry to this file. I tried a "mvn dependency:tree" and it lists this fine. Can someone tell me what is going wrong here?

• How can I save BioPerl sequence nested features in genbank or embl format?

  - by Ryan Thompson

  In BioPerl, a sequence object can have any number of features, and each of these can have subfeatures nested within them. For example, a feature may be a complete coding sequence of a gene, and its subfeatures might be individual exons that are concatenated to form the full coding sequence. However, when I use BioPerl to write a sequence object to a file in genbank or embl format, only the top-level features are written to the file, not the sub-features nested within the top-level features. How can I store my subfeatures in sequence files? Should I just convert all my subfeatures into top-level features, and then reconstruct the tree structure next time I read in the sequence?

• Storing millions of URLs in a database for fast pattern matching

  - by Paras Chopra

  I am developing a web analytics kind of system which needs to log referring URL, landing page URL and search keywords for every visitor on the website. What I want to do with this collected data is to allow end-user to query the data such as "Show me all visitors who came from Bing.com searching for phrase that contains 'red shoes'" or "Show me all visitors who landed on URL that contained 'campaign=twitter_ad'", etc. Because this system will be used on many big websites, the amount of data that needs to log will grow really, really fast. So, my question: a) what would be the best strategy for logging so that scaling the system doesn't become a pain; b) how to use that architecture for rapid querying of arbitrary requests? Is there a special method of storing URLs so that querying them gets faster? In addition to MySQL database that I use, I am exploring (and open to) other alternatives better suited for this task.
