  • PHP variable in variable

    - by FFish
    I have set an array in my config file that I use global in my functions. This works fine, but now I want to pass the name of this array as a @param in my function. // in config file: $album_type_arr = array("appartamento", "villa"); global $album_type_arr; // pull in from db_config echo $album_type_arr[0]; function buildmenu($name) { $test = global $name . "_arr"; echo $test[0]; } buildmenu("album_type");

  • What is a proper way to pass a parameter to Set-Alias in powershell?

    - by Nick Gorbikoff
    Hello. A little background: I use PowerShell on windows xp at work and I set a bunch of useful shortcuts in Microsoft.PowerShell_profile.ps1 in My Documents, trying to emulate Mac environment inspired by Ryan Bates's shortcuts I have things like: Set-Alias rsc Rails-Console function Rails-Console {Invoke-Expression "ruby script/console"} Which works just fine when in command prompt I say: rsc #it calls the proper command However this doesn't work properly Set-Alias rsg Rails-Generate function Rails-Generate {Invoke-Expression "ruby script/generate"} So when I do : rsg model User which is supposed to call ruby script/generate model User all it calls is ruby script/generate #Dumping my params So how would I properly modify my functions to take params I send to functions? Thank you!!

  • Which Devices Support Javascript Geolocation via navigator.geolocation ?

    - by Maciek
    The iPhone supports geolocation in mobile Safari via the following call: navigator.geolocation.getCurrentPosition( function(pos){ var lat = pos.coords.latitude; var long = pos.coords.longitude; }, function(){ /* Handler if location could not be found */ } ); I'd like to build a good list of devices that have one of the following: support this feature out of the box, or support this feature with an upgrade, or support geolocation with equivalent fidelity of data with some other snippet of Javascript. I'm only familiar with my own device, so this is my list so far: Out of the box: iPhone 3GS Supported, but only with an update iPhone 3G iPhone 2G (?) PC or Mac computer with Firefox 3.5 Supported with some other snippet ? What is the level of support in Blackberry, Android phones, etc?

  • PHP - can a method return a pointer?

    - by Kerry
    I have a method in a class trying to return a pointer: <?php public function prepare( $query ) { // bla bla bla return &$this->statement; } ?> But it produces the following error: Parse error: syntax error, unexpected '&' in /home/realst34/public_html/s98_fw/classes/sql.php on line 246 This code, however, works: <?php public function prepare( $query ) { // bla bla bla $statement = &$this->statement; return $statement; } ?> Is this just the nature of PHP or am I doing something wrong?

  • iPhone Mapkit Blue Dot / User Location Region Zoom Question

    - by user290031
    Hey All, Is is possible to set a region based on a current location in a mapview only one time. I want my iphone app to get the current location, zoom into that current location, and then allow the user to scroll around. However, because my setRegion code is in my didUpdateToLocation function, every time the current location is updated, so is the region, and I can't scroll around on the map. I tried putting this setRegion code in the viewDidLoad function, but the user's current location isn't initialized at this point, so it doesn't work right. Any ideas?

    .NET I want to clone a value type's fields. How can i set a field value on a value type using reflection (or something else dynamically)? This works for reference types but not for value types. I understand why but I don't know an alternative. shared function clone(of t)(original as t) as t dim cloned as t 'if class then execute parameterless constructor if getType(t).isClass then cloned = reflector.construct(of t)() dim public_fields = original.getType.getFields() for each field in public_fields dim original_value = field.getValue(original) 'this won't work for value type, but it does work for reference type ??? field.setValue(cloned, original_value) next return cloned end function

  • Safely adding SSH users to pfSense

    - by Goyuix
    I would like to add a user for myself to login via SSH to a pfSense box. I don't want to just blindly go through the adduser command and inadvertently break something / open a vulnerability somewhere though. Looking at the config page in the WebUI: I can't find where to add users or to specify their keys. What is the right way to add users that can use SSH? Can I also safely use the AllowUsers directive to keep tighter control of those allowed to login via SSH? Bonus: I would also like to disable root from being able to login via SSH. I can see the option PermitRootLogin in the /etc/ssh/sshd_config file, though I don't necessarily want to modify it directly as I could potentially lose those changes with updates/patches or changes through the WebUI. Thoughts?

  • XHR readyState = 4 but Status = 0 in Google Chrome Browser

    - by Jay
    Hello i'v got a strange Problem with an AJAX call on my site. I make a simple AJAX call to a Script on my site. But the AJAX call fails with readState=4 and Staus = 0. There's no cross domain problem because the script i want to call is on my server. $.ajax({ type:"GET", url: 'http://mydomain.com/test.php', success : function(response){ console.log(response); }, error : function(XHR){ console.log(arguments); } }); I 've googled a lot of sites but there seems to be no solution for that!

  • QTableWidget signal cellChanged(): distinguish between user input and change by routines

    - by crabman
    i am using PyQt but my question is a general Qt one: I have a QTableWidget that is set up by the function updateTable. It writes the data from DATASET to the table when it is called. Unfortunately this causes my QTableWidget to emit the signal cellChanged() for every cell. The signal cellChanged() is connected to a function on_tableWidget_cellChanged that reads the contents of the changed cell and writes it back to DATASET. This is necessary to allow the user to change the data manually. So everytime the table is updated, its contents are written back to DATASET. Is there a way to distinguish if the cell was changed by the user or by updateTable? i thought of disconnecting on_tableWidget_cellChanged by updateTable temporarily but that seems to be a little dirty.

  • Graphing perpendicular offsets in a least squares regression plot in R

    - by D W
    I'm interested in making a plot with a least squares regression line and line segments connecting the datapoints to the regression line as illustrated here in the graphic called perpendicular offsets: http://mathworld.wolfram.com/LeastSquaresFitting.html I have the plot and regression line done here: ## Dataset from http://www.apsnet.org/education/advancedplantpath/topics/RModules/doc1/04_Linear_regression.html ## Disease severity as a function of temperature # Response variable, disease severity diseasesev<-c(1.9,3.1,3.3,4.8,5.3,6.1,6.4,7.6,9.8,12.4) # Predictor variable, (Centigrade) temperature<-c(2,1,5,5,20,20,23,10,30,25) ## Fit a linear model for the data and summarize the output from function lm() severity.lm <- lm(diseasesev~temperature,data=severity) # Take a look at the data plot( diseasesev~temperature, data=severity, xlab="Temperature", ylab="% Disease Severity", pch=16 ) abline(severity.lm,lty=1) title(main="Graph of % Disease Severity vs Temperature") Should I use some kind of for loop and segments http://www.iiap.res.in/astrostat/School07/R/html/graphics/html/segments.html to do the perpendicular offsets? Is there a more efficient way? Please provide an example if possible.

  • Running emacs in GNU Screen overrides .emacs settings for [home] key binding in FreeBSD 8.2

    - by javanix
    If I use the following .emacs file, I am able to go to the beginning/end of the current line using the home/end keys as I would expect. (keyboard-translate ?\C-h ?\C-?)

  • not so obvious pointers

    - by mike_hornbeck
    I have a class : class X{ public : void f ( int ) ; int a ; } ; And the task is "Inside the code provide declarations for : pointer to int variable of class X pointer to function void(int) defined inside class X pointer to double variable of class X" Ok so pointer to int a will be just int *x = &a, right ? If there is no double in X can I already create pointer to double inside this class ? And the biggest problem is the second task. How one declares pointer to function ?

  • Problems with Widgets in dojox DataGrid

    - by Kitson
    I am trying to include some editing Widgets in my dojox.grid.DataGrid seem to be having a lot of difficulty. I have tried everything I can think of to get it to work, but something just isn't going right. When I started having problems, I tried to copy almost exactly from the grid tests and model my "breakout" of code just like that, but without success. Basic editing of the Grid seems to work. In the example below, the "Events" column allows edits, but the two columns that are using the cellType attribute don't work. In fact they also seem to ignore the other attributes (like the styles) which would seem to indicate that some sort of issue was run into, but there is nothing in FireBug. Also I get the same behaviour between Chrome and Firefox. <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> <title>Insert title here</title> <link id="themeStyles" rel="stylesheet" href="javascript/dojotoolkit/dijit/themes/tundra/tundra.css"> <style type="text/css"> @import "css/gctilog.css"; @import "javascript/dojotoolkit/dojo/resources/dojo.css"; @import "javascript/dojotoolkit/dijit/themes/tundra/tundra.css"; @import "javascript/dojotoolkit/dojox/grid/resources/Grid.css"; @import "javascript/dojotoolkit/dojox/grid/resources/tundraGrid.css"; @import "javascript/dojotoolkit/ocp/resources/MultiStateCheckBox.css"; </style> <script type="text/javascript" src="javascript/dojotoolkit/dojo/dojo.js" djConfig="parseOnLoad:true, isDebug:true, locale:'en-gb'"></script> <script type="text/javascript"> dojo.require("dojo.currency"); dojo.require("dijit.dijit"); dojo.require("dijit.form.HorizontalSlider"); dojo.require("dojox.data.JsonRestStore"); dojo.require("dojox.grid.DataGrid"); dojo.require("dojox.layout.ExpandoPane"); dojo.require("dojox.timing"); dojo.require("ocp.MultiStateCheckBox"); dojo.require("dojo.parser"); formatCurrency = function(inDatum){ return isNaN(inDatum) ?

  • CComPtr pass by reference

    - by Mahesh
    I have a situation where I need to pass a CComPtr<IXmlReader> to a function by reference. Does the called parameter takes the ownership from the callee parameter (or) the reference count is increased? void foo( CComPtr<IXmlReader> & pReader ) { // There is no reassignment of the CComPtr. // Just call the IXmlReader methods. } CComPtr<IXmlReader> pReader; foo( pReader ); // Is pReader still valid after the function return ? Thanks.

  • Scheme: Detecting duplicate elements in a list

    - by Kyle Krull
    Does R6RS or Chez Scheme v7.9.4 have a library function to check if a list contains duplicate elements? Alternatively, do either have any built in functionality for sets (which dis-allow duplicate elements)? So far, I've only been able to find an example here. The problem with that is that it doesn't appear to actually be part of the Chez Scheme library. Although I could write my own version of this, I'd much rather use a well known, tested, and maintained library function - especially given how basic an operation this is. So a simple "use these built-in functions" or a "no built-in library implements this" will suffice. Thanks!

  • display image and script for a set period of time

    - by Ryan Max
    This is very similar to a question I asked the other day but my page code has become significantly more complicated and I need to revisit it. I've been using the following code: $('#myLink').click(function() { $('#myImg').attr('src', 'newImg.jpg'); setTimeout(function() { $('#myImg').attr('src', 'oldImg.jpg'); }, 15000); }); To replace an image for a set period of time (15 seconds) when the link is clicked, then after 15 seconds, revert to the original image. However now, I'd like to run a snippet of javascript as well when the link is clicked (in addition to replacing the image), and only when the link is clicked (it's related to the 15 second image) and then have the js code disappear as well after the 15 seconds...however I'm not sure how to have jquery send js code into the page...Basically I just want jQuery to "echo" this code onto the page underneath the 15 second while I am there, but I don't know how jquery formats this "echo". Does this question make sense?

  • VPN for a small organization

    - by user24091
    I am in charge of a small office network that has < 10 users. I want to be able to offer them access to the network from their home internet connections. At the moment we have a regular ADSL-router-firewall to provide local network access and a fixed IP address. I know there are enterprise-level VPN solutions, but these obviously won't be available to us because of the cost and complexity. What small-scale solutions are around that you could recommend, what would we need to deploy on the client side, and what would the clients need to do to access the VPN? Simplicity and low cost need to be the keys here. Thanks

    Can some pls help with the solution Use big-O notation to classify the traditional grade school algorithms for addition and multiplication. That is, if asked to add two numbers each having N digits, how many individual additions must be performed? If asked to multiply two N-digit numbers, how many individual multiplications are required? Suppose f is a function that returns the result of reversing the string of symbols given as its input, and g is a function that returns the concatenation of the two strings given as its input. If x is the string hrwa, what is returned by g(f(x),x)? Explain your answer - don't just provide the result!

  • Properties of bad fibonacci algorithm

    - by John Smith
    I was looking at the canonical bad fibonacci algorithm the other day: public static int fib(int n) { // Base Case if (n < 2) return 1; else return fib(n-1) + fib(n-2); } I made the interesting observation. When you call fib(n), then for k between 1 and n fib(k) is called precisely fib(n-k+1) times (or fib(n-k) depending on your definition of fib(0) ). Also, fib(0) is called fib(n-k-1) times. This then allows me to find that in fib(100) there are exactly 708449696358523830149 calls to the fib function. Are there other interesting observations on this function you know of?
