  • Can I pass an argument to a VBScript (vbs file launched with cscript)?

    - by Peter
    I have this script saved in "test.vbs": Set FSO = CreateObject("Scripting.FileSystemObject") Set File = FSO.OpenTextFile(workFolder &"\test.txt", 2, True) File.Write "testing" File.Close Set File = Nothing Set FSO = Nothing Set workFolder = Nothing When I run the script I want to pass the value of the "workFolder" variable. How can I do this? Can I do it? Something like "cscript test.vbs workFolder:'C:\temp\'" perhaps? Bonus question: Is it neccessary to clean up the passed variable with "Set workFolder = Nothing" or does VBSCript do that automatically when it terminates? Maybe "Set File = Nothing" and "Set FSO = Nothing" is unneccessary also? Please let me know if you know the answer to both these questions.

  • How can I get a value from an xml key/value pair with xpath in my xslt?

    - by TahoeWolverine
    I have some xml that I want to process using xslt. A good amount of the data comes through in key value pairs (see below). I am struggling with how to extract the value base on the key into a variable. I would like to be able to do something like this: <xsl:variable name="foo" select="/root/entry[key = 'foo']/value"/> but that doesn't seem to work. Here is sample xml. <?xml version="1.0" encoding="ISO-8859-1"?> <root> <entry> <key> foo </key> <value> bar </value> </entry> </root> What would the correct xpath be for this?

  • Strange behaviour of switch case with boolean value

    - by Nikhil Agrawal
    My question is not about how to solve this error(I already solved it) but why is this error with boolean value. My function is private string NumberToString(int number, bool flag) { string str; switch(flag) { case true: str = number.ToString("00"); break; case false: str = number.ToString("0000"); break; } return str; } Error is Use of unassigned local variable 'str'. Bool can only take true or false. So it will populate str in either case. Then why this error? Moreover this error is gone if along with true and false case I add a default case, but still what can a bool hold apart from true and false? Why this strange behaviour with bool variable?

  • (iPhone SDK) How to link instance variables to a specific UILabel

    - by Timbo
    I'm using the iPhone SDK to build a simple application. I've created a brand new class which has a single variable. I need to make 5 instances of that class, which I have no trouble doing. I can create those instances and also set the variables without issue. What i do need to know is this: How do I link each of the 5 different instances of the variable to different and specific UILabels? Would I be better to create a method that dynamically creates and positions the labels? Thanks for your help in advance, I'm now to this iphone programming thing. I'm serious about learning fast though so I have posted a bounty on this question here : http://www.askearn.com/Responses.aspx?QuestionID=6542613f-7be8-4bb3-a950-aac218d47711

  • RCP applicatoon activities

    - by Peter
    I have a problem with my RCP application. First, I defined an activity in my plugin.xml: <extension point="org.eclipse.ui.activities"> <activity id="myproject.view.input.activity" name="myproject.view.input.activity"> <enabledWhen> <with variable="myproject.view.input.active"> <equals value="ENABLED"> </equals> </with> </enabledWhen> </activity> <activityPatternBinding activityId="myproject.view.input.activity" pattern="myproject.gui/myproject.view.input"> </activityPatternBinding> Then i defined my SourceProvider: <extension point="org.eclipse.ui.services"> <sourceProvider provider="myproject.util.CommandState"> <variable name="myproject.view.input.active" priorityLevel="workbench"> </variable> And, finally, my CommandState class: public class CommandState extends AbstractSourceProvider { public final static String OUTPUT_VIEW = "myproject.view.input.active"; // then goes some others variables, i just skip them // .... public final static String [] ACTIONS = {OUTPUT_VIEW /*and all others variables*/}; public final static String ENABLED = "ENABLED"; public final static String DISENABLED = "DISENABLED"; private final Map <String, String> currentState = new HashMap <String, String> (); @Override public void dispose() { } @Override public String[] getProvidedSourceNames() { return ACTIONS; } @Override public Map <String, String> getCurrentState() { return currentState; } public void setEnabled(boolean enabled, String [] commands) { String value = enabled ? ENABLED : DISENABLED; for (String command : commands) { currentState.put(command, value); fireSourceChanged(ISources.WORKBENCH, command, value); } } } In my Login window, application checks user permissions, and enable or disable views, commands, etc. with setEnabled method of CommandState. For commands it works fine, they are enabling or disabling correctly. But when i try to disable view and open perspective, that contains that view (myproject.view.input), it opened without that view, but also throws exception: !STACK 1 org.eclipse.ui.PartInitException: Could not create view: myproject.view.input at org.eclipse.ui.internal.ViewFactory.createView(ViewFactory.java:158) I can show full stacktrace if anyone want. I tried to debug my application and before i open my perspective whith that view, i checked currentState of my CommandState source provider, and all seemes to be ok: all variables values are correct and myproject.view.input.active = DISABLED Can anyone say, why exception is thrown? Thanks for any help. Sorry for big post and bad language

  • ruby on rails params injection

    - by Julien P.
    Hello everyone, I have a question about ruby on rails and the process of assigning variables using the params variable passed through a form class User attr_accessible :available_to_admins, :name end Let's say that I have a field that is only available to my admins. Assuming that you are not an admin, I am going to not display the available_to_admins input in your form. After that, when I want to save your data I'll just do a: User.update_attributes(params[:user]) If you are an admin, then no problem, the params[:user] is going to contain name and available_tu_admins and if you're not then only your name. Since the available_to_admins is an attr_accessible parameter, how should I prevent non admin users from being able to inject a variable containing the available_to_admins input with their new value?

  • Sening a file from memory (rather than disk) over HTTP using libcurl

    - by cinek1lol
    Hi! I would like to send pictures via a program written in C + +. - OK WinExec("C:\\curl\\curl.exe -H Expect: -F \"fileupload=@C:\\curl\\ok.jpg\" -F \"xml=yes\" -# \"http://www.imageshack.us/index.php\" -o data.txt -A \"Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1\" -e \"http://www.imageshack.us\"", NULL); It works, but I would like to send the pictures from pre-loaded carrier to a variable char (you know what I mean? First off, I load the pictures into a variable and then send the variable), cause now I have to specify the path of the picture on a disk. I wanted to write this program in c++ by using the curl library, not through exe. extension. I have also found such a program (which has been modified by me a bit) #include <stdio.h> #include <string.h> #include <iostream> #include <curl/curl.h> #include <curl/types.h> #include <curl/easy.h> int main(int argc, char *argv[]) { CURL *curl; CURLcode res; struct curl_httppost *formpost=NULL; struct curl_httppost *lastptr=NULL; struct curl_slist *headerlist=NULL; static const char buf[] = "Expect:"; curl_global_init(CURL_GLOBAL_ALL); /* Fill in the file upload field */ curl_formadd(&formpost, &lastptr, CURLFORM_COPYNAME, "send", CURLFORM_FILE, "nowy.jpg", CURLFORM_END); curl_formadd(&formpost, &lastptr, CURLFORM_COPYNAME, "nowy.jpg", CURLFORM_COPYCONTENTS, "nowy.jpg", CURLFORM_END); curl_formadd(&formpost, &lastptr, CURLFORM_COPYNAME, "submit", CURLFORM_COPYCONTENTS, "send", CURLFORM_END); curl = curl_easy_init(); headerlist = curl_slist_append(headerlist, buf); if(curl) { curl_easy_setopt(curl, CURLOPT_URL, "http://www.imageshack.us/index.php"); if ( (argc == 2) && (!strcmp(argv[1], "xml=yes")) ) curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headerlist); curl_easy_setopt(curl, CURLOPT_HTTPPOST, formpost); res = curl_easy_perform(curl); curl_easy_cleanup(curl); curl_formfree(formpost); curl_slist_free_all (headerlist); } system("pause"); return 0; }

  • var undefined = true;

    - by Andreas Grech
    I'm doing some experimenting with this malicious JavaScript line: var undefined = true; Every uninitialized variable in JavaScript has the value of undefined which is just a variable that holds the special value of 'undefined', so the following should execute the alert: var undefined = true, x; if (x) { alert('ok'); } But it doesn't, and my question is why? On further experimentation, I tried the following: var undefined = true, x = undefined; if (x) { alert('ok'); } This time, the alert is executed. So my question is...since in the first snippet x holds undefined (because it is not initialized), why didn't the alert execute? The strange thing is that when explicitly stating that x is undefined (x = undefined), the alert executed...

  • How can I pass data from an aspx page to an ascx modal popup?

    - by Erick B
    I'm fairly new to ASP.NET and trying to learn how things are done. I come from a C# background so the code-behind portion is easy, but thinking like a web developer is unfamiliar. I have an aspx page that contains a grid of checkboxes. I have a button that is coded via a Button_Click event to collect a list of which rows are checked and create a session variable out of that list. The same button is referenced (via TargetControlID) by my ascx page's ModalPopupExtender which controls the panel on the ascx page. When the button is clicked, the modal popup opens but the Button_Click event is never fired, so the modal doesn't get its session data. Since the two pages are separate, I can't call the ModalPopupExtender from the aspx.cs code, I can't reach the list of checkboxes from the ascx.cs code, and I don't see a way to populate my session variable and then programmatically activate some other hidden button or control which will then open my modal popup. Any thoughts?

  • git- how to troubleshoot "cannot find command"

    - by Frank Schwieterman
    I need help getting git extensions to run with msysgit. I have had bad luck with extensions git-tfs and git-fetchall, in both cases it is the same problem. The addon will require a file to be placed where git can find it (git-tfs.exe and git-fetchall.sh). I understand this to mean the files need to be in a directory that is in the 'PATH' environment variable. In both cases I get stuck at this point: $ git-diffall bash: git-diffall: command not found When I run echo %PATH% from a regular command shell, it shows my path variable includes the directories where git-diffall and git-tfs are. How can I debug this, or am I missing something? Is there a way within msysgit to verify the command search path is what I expect?

  • PHP Menu Question

    - by Vecta
    As one of the steps toward a greater website redesign I am putting the majority of the content of our website into html files to be used as includes. I am intending on passing a variable to the PHP template page through the URL to call the proper include. Our website has many programs that each need an index page as well as about 5 sub-pages. These program pages will need a menu system to navigate between the different pages.I am naming the pages pagex_1, pagex_2, pagex_3, etc. where "pagex" is descriptive of the page content. My question is, what would be the best way to handle this menu system? Is there a way to modify the initial variable used to arrive at the index page to create links in the menu to arrive at the other pages? Thanks for any help!

  • JavaScript function binding (this keyword) is lost after assignment

    - by Ding
    this is one of most mystery feature in JavaScript, after assigning the object method to other variable, the binding (this keyword) is lost var john = { name: 'John', greet: function(person) { alert("Hi " + person + ", my name is " + this.name); } }; john.greet("Mark"); // Hi Mark, my name is John var fx = john.greet; fx("Mark"); // Hi Mark, my name is my question is: 1) what is happening behind the assignment? var fx = john.greet; is this copy by value or copy by reference? fx and john.greet point to two diferent function, right? 2) since fx is a global method, the scope chain contains only global object. what is the value of this property in Variable object?

  • PHPMailer safe practices - Send escaped / sanitized variables or not ?

    - by FreekOne
    I'm using the PHPMailer-Lite class to build an email sending script and I'm not sure if I should use addslashses() on the $name variable when adding it to the constructor. If somebody's last name would be O'Riley (or any other name that contains characters which should normally be sanitized before handling) and I would send it unescaped, wouldn't it mess with the script/email sending ? Is it safe to send it unescaped ? As a side note, I would also like to avoid having my message body say "Hello, O\'Riley". Looking at the source, I saw that it only trims the whitespace and line ending (\r\n) characters from the received $name variable, so any advice on this would be more than welcome. Thank you all in advance !

  • Global variables in jQuery

    - by Thorpe Obazee
    I have been working on this script: <script type="text/javascript" src="/js/jquery.js"></script> <script type="text/javascript"> $(function(){ compentecy = $('#competency_id'); $('#add_competency').bind('click', function(e){ e.preventDefault(); $.post('/script.php', {competency_id: compentecy.val(), syllabus_id: 2}, function(){ // competency = $('#competency_id'); competency.children('option[value=' + compentecy.val() + ']').remove(); }); }); }); </script> in the $.post callback function, it seems that I can't access global variables. I tried $.competency but it didn't work. I always get a "competency is undefined" error. I had to reinitialize the variable once again inside the callback. Is there a way to NOT reinitialize the variable inside the callback?

  • I need to know what link is clicked, how do i get these variables with cherrypy?

    - by user291071
    Lets say I display 3 links, I want to accomplish 2 things, know which link is clicked, and record this choice in a list/pickle or txt file but also capture this variable in cherrypy so I can perform another action. How do I do this? Its been suggested that I use a query string which makes sense but I can't get the querystring variable to cherrypy to use for further actions. So would anyone have a simple code of cherrypy with lets say 2 pages and have one page display 2 links with a querystring in each and the second page able to get that value?

  • Regarding BigDecimal

    - by arav
    i do the below java print command for this double variable double test=58.15; When i do a System.out.println(test); and System.out.println(new Double(test).toString()); It prints as 58.15. When i do a System.out.println(new BigDecimal(test)) I get the below value 58.14999999999999857891452847979962825775146484375 I am able to understand "test" double variable value is internally stored as 58.1499999. But when i do the below two System.out.println i am getting the output as 58.15 and not 58.1499999. System.out.println(test); System.out.println(new Double(test).toString()); It prints the output as 58.15 for the above two. Is the above System.out.println statements are doing some rounding of the value 58.1499999 and printing it as 58.15?

  • Grabbing random object from ArrayList is not random.

    - by Isai
    I am creating a method where if you pass in a parameter of type Random, then it will return a random object. Here is basically what I am trying to do: public T choose(Random r) { int randomInt = r.nextInt(randomList.size()); // randomList is just a instance variable return randomList.get(randomInt); } The random list has this the following strings:[2, 2, 2, 1, 1, 1, 1, c, c, c, a, a, a, a] Then I made a driver with the following code for (int i = 0; i < 10; i++) { System.out.print(rndList.choose(rnd)); // rnd is initialized as a static Random variable } However my outputs are not coming out random. I used the debugger and found out that my choose method generates an integer that is relatively low, so it will always print out either 2's or 1's but never c's or a's. I can't figure out why this is happening and help would be greatly appreciated.

  • Inside a decorator-class, access instance of the class which contains the decorated method

    - by ifischer
    I have the following decorator, which saves a configuration file after a method decorated with @saveconfig is called: class saveconfig(object): def __init__(self, f): self.f = f def __call__(self, *args): self.f(object, *args) # Here i want to access "cfg" defined in pbtools print "Saving configuration" I'm using this decorator inside the following class. After the method createkvm is called, the configuration object self.cfg should be saved inside the decorator: class pbtools() def __init__(self): self.configfile = open("pbt.properties", 'r+') # This variable should be available inside my decorator self.cfg = ConfigObj(infile = self.configfile) @saveconfig def createkvm(self): print "creating kvm" My problem is that i need to access the object variable self.cfg inside the decorator saveconfig. A first naive approach was to add a parameter to the decorator which holds the object, like @saveconfig(self), but this doesn't work. How can I access object variables of the method host inside the decorator? Do i have to define the decorator inside the same class to get access?

  • Are these two functions overkill for sanitization?

    function sanitizeString($var) { $var = stripslashes($var); $var = htmlentities($var); $var = strip_tags($var); return $var; } function sanitizeMySQL($var) { $var = mysql_real_escape_string($var); $var = sanitizeString($var); return $var; } I got these two functions from a book and the author says that by using these two, I can be extra safe against XSS(the first function) and sql injections(2nd func). Are all those necessary? Also for sanitizing, I use prepared statements to prevent sql injections. I would use it like this: $variable = sanitizeString($_POST['user_input']); $variable = sanitizeMySQL($_POST['user_input']);

  • Assembly stack persistency

    - by user246100
    Hello. I would like to know if after calling functions the data I have in the stack is persistent. Like, I would like to know if (assuming cdecl convention) can I do this (independently of function X and independently of optimizations): push 1 push 2 push 3 call X call X call X add 12 esp ? Also, let's say that before the calls I save the address of where the pushed values are in a global variable. Can I, inside X, alter the values it contain by acessing the global variable? Like, for some reason I want that in X I'm able to alter the values in stack so that the second and third call to X receive different values.

  • How do you handle browser cache with login/logout?

    - by Julien
    To improve performances, I'd like to add a fairly long Cache-Control (up to 30 minutes) to each page since they do not change often. However, each page also displays the name of the user logged in (like this website). The problem is when the user logs in or logs out: the user name must change. How can I change the user name after each login/logout action while keeping a long Cache-Control? Here are the solutions I can think of: Ajax request (not cached) to retrieve and display the user name. If I have 2 requests (/user?registered and /user?new), they could be cached as well. But I am afraid this extra request would nullify my caching performance-wise Add a unique URL variable (?time=) to make the URL different, and cancel the cache. However, I would have to add this variable to all links on my webpage, not very convenient code-wise This problems becomes greater if I actually have more content that is not the same for registered users and new users.

  • Eta/Eta-squared routines in R

    - by aL3xa
    Apart from graphical estimation of linearity (gaze-at-scatterplot method), which is utilized before applying some technique from GLM family, there are several ways to do this estimation arithmetically (i.e. without graphs). Right now, I'll focus on Fisher's eta-squared - correlation ratio: arithmetically, it's equal to squared Pearson's r (coef. of determination: R2) if relationship between two variables is linear. Hence, you can compare values of eta and r and make an assessment about type of relation (linear or not). It provides an information about percent of variance in the dependent variable explained (linearly or not) by the independent variable. Therefore, you can apply it when linearity assumptions are not met. Simply stated: is there a routine for eta/eta-squared in R?
