  • How to run perl script with a few arguments from php

    - by Cristalla
    My html webpage calls php script to upload files to the server from a local computer as follows. <form enctype="multipart/form-data" action="upload.php" method="POST"> <p><b><h3> <font color="#003366"> (1) Upload your reading text file. </font> </h3> </b> </p> <INPUT type="file" name="uploaded" size="50" > <br/> <input type="submit" name="files" value="upload"> </form> In order to process with an uploaded file, my php script calls shell script $output=system('/bin/sh connector_0.sh'); and my shell script is composed of a series of python/perl scripts. #!/bin/sh python main_senselearner_final_0.py senseLearner.pl -i Uploaded_Files/slinput_0.txt -o Uploaded_Files/presloutput_0 .txt -model modelNNCollocations -model modelJJCollocations -model modelVBColloc ations -pos python smutngslout_0.py python genhtml_0.py Now, the problem is the following: all python scripts in shell script worked fine through php. But perl script didn't work. When I run shell script by myself in my server, all four scripts in shell worked perfectly. However, when I run shell script from php, only perl script doesn't work. Would you please give me any tips to solve this problem? Many thanks!!!

  • Python & Pygame: Updating all elements in a list under a loop during iteration

    - by Unit978
    i am working on a program in Python and using Pygame. this is what the basic code looks like: while 1: screen.blit(background, (0,0)) for event in pygame.event.get(): if event.type == QUIT: pygame.quit() sys.exit() if event.type == KEYDOWN and event.key == K_c: circle_create = True circle_list.append(Circle()) if event.type == MOUSEBUTTONDOWN and circle_create == True: if clicks == 0: circle_list[i].center() clicks += 1 if event.type == MOUSEMOTION and clicks == 1 and circle_create == True: circle_list[i].stretch() these if statements are under the while loop not the for loop since they dont require input from the user if circle_create == True: circle_list[i].draw_circle() if clicks == 2: clicks = 0 i += 1 circle_create = False pygame.display.update() what i want to do is have the object's function of draw_circle() to be constantly updated by the loop so that the drawn circle is shown for all objects in the list, but since the list is iterated it updates the new object added and the objects already appended are not updated. The program, works, it draws the circles upon user input but the update problem is the only issue i need to solve. Is there any possible way to have all elements in the list of objects being updated by the while loop? i have tried for many days and i have not been able to find a good solution. any ideas are appreciated. Thanks

  • jQuery Ajax call for buttons on a list

    - by lloydphillips
    I have a list of data that i have in a view from an asp.net mvc application. It's a list of stock and I have two images (a plus and a minus) on the end of each row which will allow me to increase or decrease stock quantity. It works fine at present with a call to the mvc action but since the list is long I want to use jQuery and AJAX to have the call go without a refresh. I want to do this with unobtrusive javascript so don't want onclick handlers on my images. Since I'm just starting out with jQuery I have no idea how I can iterate all the images and add the function. Here are the images with the form tags as they stand: <td> <% using (Html.BeginForm("Increase", "Stock", new { Id = item.StockId })) {%> <input type="image" src="/Content/Images/bullet_add.png" style="margin-left:20px;" /> <% } %> </td> <td><% using (Html.BeginForm("Decrease", "Stock", new { Id = item.StockId })) {%> <input type="image" src="/Content/Images/bullet_delete.png" style="margin-left:10px;" /><% } %> </td> Can anyone help me out a little? Many thanks. Lloyd

  • Capture data from jQuery Mobile GUI / form elements like sliders, or the flip switch/toggle, and store in a var?

    - by Carl Foggin
    I have this code, which executes without error, it shows "** slider change **" in the debug console every time the slider changes. But I cannot figure out how to capture the value of the slider so I can store it in a var. Can you help, I'm hoping it's a simple thing. $( '#page4_Options' ).live( 'pageinit', function(event){ var slideTime = userOptions.getSlideTime() / 1000; // userOptions is my Object to get/set params from localStorage. $("input[id='slider']").val(slideTime).slider("refresh"); // set default slide time when page init's. console.log("userOptions.getSlideTime()", userOptions.getSlideTime() ); $( "#slider" ).bind( "slidestop", function(event, ui) { console.log("** slider change **"); // How do I capture the new slider value into a var? }); }); Here's the HTML with the slider, it's in a tag: <div data-role="fieldcontain"> <label for="slider">Slide Duration (seconds):</label> <input type="range" name="slider" id="slider" value="2" min="0" max="60" /> </div>

  • If statement String trouble

    - by Jeremy Stone
    I'm trying to create a program which takes user input of two words and determines whether or not these words are the same. import java.util.Scanner; public class L7E3 { public static void main(String[] args) { Scanner keyboard = new Scanner(System. in ); String word1, word2; System.out.println("Please enter a word: "); word1 = keyboard.nextLine(); System.out.println("Please enter a word: "); word2 = keyboard.nextLine(); if (word1 == word2) { System.out.println("The words are " + word1 + " and " + word2 + ". These words are the same."); } else { System.out.println("The words are " + word1 + " and " + word2 + ". These words are not the same."); } } } I figured that word1==word2 would have worked to determine whether the two strings were equal, I'm using JGrasp and it goes directly to my else option regardless of input. Am I doing something wrong with strings?

  • Basic user authentication with records in AngularFire

    - by ajkochanowicz
    Having spent literally days trying the different, various recommended ways to do this, I've landed on what I think is the most simple and promising. Also thanks to the kind gents from this SO question: Get the index ID of an item in Firebase AngularFire Curent setup Users can log in with email and social networks, so when they create a record, it saves the userId as a sort of foreign key. Good so far. But I want to create a rule so twitter2934392 cannot read facebook63203497's records. Off to the security panel Match the IDs on the backend Unfortunately, the docs are inconsistent with the method from is firebase user id unique per provider (facebook, twitter, password) which suggest appending the social network to the ID. The docs expect you to create a different rule for each of the login method's ids. Why anyone using 1 login method would want to do that is beyond me. (From: https://www.firebase.com/docs/security/rule-expressions/auth.html) So I'll try to match the concatenated auth.provider with auth.id to the record in userId for the respective registry item. According to the API, this should be as easy as In my case using $registry instead of $user of course. { "rules": { ".read": true, ".write": true, "registry": { "$registry": { ".read": "$registry == auth.id" } } } } But that won't work, because (see the first image above), AngularFire sets each record under an index value. In the image above, it's 0. Here's where things get complicated. Also, I can't test anything in the simulator, as I cannot edit {some: 'json'} To even authenticate. The input box rejects any input. My best guess is the following. { "rules": { ".write": true, "registry": { "$registry": { ".read": "data.child('userId').val() == (auth.provider + auth.id)" } } } } Which both throws authentication errors and simultaneously grants full read access to all users. I'm losing my mind. What am I supposed to do here?

  • Will C++/CLI give me control over low-level devices like audio?

    - by schmoopy
    I was wondering - how much limitation is there to C++/CLI compared to classic C++ (chuckle) - I was wanting to write an application that I cannot do with c# -- I was wanting to be able to connect to the PC's audio device and detect audio (for example) - Is this something I can do with C++/CLI? I have tried using NAudio with c#, but i have been able to do this. What other advantages would C++/CLI or C++ give me over c#?

  • MD5CryptoServiceProvider ComputeHash Issues between VS 2003 and VS 2008

    - by owensoroke
    I have a database application that generates a MD5 hash and compares the hash value to a value in our DB (SQL 2K). The original application was written in Visual Studio 2003 and a deployed version has been working for years. Recently, some new machines on the .NET framework 3.5 have been having unrelated issues with our runtime. This has forced us to port our code path from Visual Studio 2003 to Visual Studio 2008. Since that time the hash produced by the code is different than the values in the database. The original call to the function posted in code is: RemoveInvalidPasswordCharactersFromHashedPassword(Text_Scrub(GenerateMD5Hash(strPSW))) I am looking for expert guidance as to whether or not the MD5 methods have changed since VS 2K3 (causing this point of failure), or where other possible problems may be originating from. I realize this may not be the best method to hash, but utimately any changes to the MD5 code would force us to change some 300 values in our DB table and would cost us a lot of time. In addition, I am trying to avoid having to redeploy all of the functioning versions of this application. I am more than happy to post other code including the RemoveInvalidPasswordCharactersFromHashedPassword function, or our Text_Scrub if it is necessary to recieve appropriate feedback. Thank you in advance for your input. Public Function GenerateMD5Hash(ByVal strInput As String) As String Dim md5Provider As MD5 ' generate bytes for the input string Dim inputData() As Byte = ASCIIEncoding.ASCII.GetBytes(strInput) ' compute MD5 hash md5Provider = New MD5CryptoServiceProvider Dim hashResult() As Byte = md5Provider.ComputeHash(inputData) Return ASCIIEncoding.ASCII.GetString(hashResult) End Function

  • How to Prevent PostBack Event Handler from Firing

    - by user331744
    I have a custom class (ServerSideValidator.vb) that validates user input on server side (it doesn't use any of the .NET built in validators, therefore Page.Validate() is not an option for me). I am calling the Validate() method on page.IsPostback event and the class performs without any problem My issue is, when validation fails (returns false), I want to stop the postback event handler from firing, but load the page along with all the controls and user-input values in them. If I do, Response.End(), the page comes up blank. I can programmatically instruct the page to go to the previous page (original form before postback), but it loses all user-inputs. I thought of creating a global boolean variable in the page code behind file and check the value before performing any postback method, but this approach takes away from my plan to provide all functionalities inside the class itself. The page object is being referenced to ServerSideValidator. Seems like all the postback related properties/variables I come across inside Page class are 'Readonly' and I can't assign value(s) to control/prevent postback event from firing. Any idiea on how I can accomplish this? Please let me know if you need further details

  • Creating new image in a loop using OpenCV

    - by user565415
    I am programing some image conversion code with OpenCV and I don't know how can I create image memory buffer to load image on every iteration. I have number of iteration (maxImNumber) and I have an input image. In every loop program must create image that is resized and modified input image. Here is some basic code (concept). for (int imageIndex = 0; imageIndex < maxImNumber; imageIndex++){ cvCopy(inputImage, images[imageIndex], 0); cvReleaseImage(&inputImage); images[imageIndex+1] = cvCreateImage(cvSize((image[imageIndex]->width)/2, image[imageIndex]->height), IPL_DEPTH_8U, 1); for (i=1; i < image[imageIndex]->height; i++) { index = 0; // for(j=0; j < image[imageIndex]->width ; j=j+2){ // doing some basic matematical operation on image content and store it to new image images[imageIndex+1][i][index] = (image[imageIndex][i][j] + image[imageIndex][i][j+2])/2; index++ } } inputImage = cvCreateImage(cvSize((image[imageIndex+1]->width), image[imageIndex]->height), IPL_DEPTH_8U, 1); cvCopy(images[imageIndex+1], inputImage, 0); } Can somebody, please, explain how can I create this image buffer (images[]) and allocate memory for it. Also how can I access any image in this buffer? Thank you very much in advance!

  • How to append html only if the div is empty in jQuery?

    - by johnnyb3000
    I have this code for displaying content for login and registration in my PHP file: <?php // LOGIN PART ?> <div class="login-part"></div> <?php // REGISTRATION PART ?> <div class="registration-part"></div> And this in my js file: $(document).ready( function() { // FOR REGISTRATION $('span.logreg.reg').click(function () { $('div.registration-part').append('<p>Registration</p>'); }); // FOR LOGIN $('span.logreg.log').click(function () { // insert html $('div.login-part').append('<p>Login</p>'); }); }); Now, everytime I click on a span it shows the text login or registration, according to which of the span was clicked. Thats OK, however I need to add it only once, so when the user click more times on the span it will be not adding more text. Remove() or empty() is not an option, as far as I know, because I need the information inside input boxes (there will be input boxes later for inserting user info) to stay there and not be deleted if the user click accidentally on the span again. It can however delete the html inside the div, if he clicks on another span. E.g. if span.log is active, after clicking on span.log nothing happens, but if he clicks on span.reg the html inside div.login-part will be removed and registration text will appear. How to do something like this?

  • Scanning, Checking, Converting, Copying values ... How to ? -- C --

    - by ZaZu
    Hi there, Its been a while now and im still trying to get a certain code to work. I asked some question about different commands etc. before, but now I hope this is the final one (combining all questions in one code). I basically want to : *Scan an input (should be character ? ) *Check if its a number *If not, return error *Convert that character into a float number *Copy the value to another variable ( I called it imp here) Here is what I came up with : #include<stdio.h> #include<stdlib.h> #include<ctype.h> main(){ int digits; float imp=0; int alpha; do{ printf("Enter input\n\n"); scanf("\n%c",&alpha); digits=isdigit(alpha); if(digits==0){ printf("error\n\n"); } imp=atof(alpha); }while(digits==0); } The problem is this code does not work at all ... It gives me that atof must be of a const char and whenever I try changing it around, it just keeps failing. I am frustrated and forced to ask here, because I believe I have tried alot and I keep failing, but I wont be relieved until I get it to work xD So I really need your help guys. Please tell me why isnt this code working, what am I doing wrong ? I am still learning C and really appreciate your help :)

  • Cant get JavaScipt to check for null objects

    - by CountMurphy
    I really don't know what the issue is here. Far as I can see, the code is simple and should work fine. var Prices=""; for (var PriceCount = 1; PriceCount <= 120; PriceCount++) { var CurrentPrice = "Price" + PriceCount; if (prevDoc.getElementById(CurrentPrice).value != null) { if (Prices == "") { Prices = prevDoc.getElementById(CurrentPrice).value; } else { Prices += "," + prevDoc.getElementById(CurrentPrice).value; } } else { break; } } There could be up to 120 hidden inputs on the form. The moment we check for an input that doesn't exist the loop should break. My test page has two input elements that get pulled. On the third (the null) I get this error in firebug: prevDoc.getElementById(CurrentPrice) is null if (prevDoc.getElementById(CurrentPrice).value != null) { Yes it is null...that's what the check is for ?_? Does any one know what I'm doing wrong? This seems like it should be really straight forward. EDIT: for clarity's sake, prevDoc=window.opener.document

  • PHP: Extract direct sub directory from path string

    - by Nebs
    I need to extract the name of the direct sub directory from a full path string. For example, say we have: $str = "dir1/dir2/dir3/dir4/filename.ext"; $dir = "dir1/dir2"; Then the name of the sub-directory in the $str path relative to $dir would be "dir3". Note that $dir never has '/' at the ends. So the function should be: $subdir = getsubdir($str,$dir); echo $subdir; // Outputs "dir3" If $dir="dir1" then the output would be "dir2". If $dir="dir1/dir2/dir3/dir4" then the output would be "" (empty). If $dir="" then the output would be "dir1". Etc.. Currently this is what I have, and it works (as far as I've tested it). I'm just wondering if there's a simpler way since I find I'm using a lot of string functions. Maybe there's some magic regexp to do this in one line? (I'm not too good with regexp unfortunately). function getsubdir($str,$dir) { // Remove the filename $str = dirname($str); // Remove the $dir if(!empty($dir)){ $str = str_replace($dir,"",$str); } // Remove the leading '/' if there is one $si = stripos($str,"/"); if($si == 0){ $str = substr($str,1); } // Remove everything after the subdir (if there is anything) $lastpart = strchr($str,"/"); $str = str_replace($lastpart,"",$str); return $str; } As you can see, it's a little hacky in order to handle some odd cases (no '/' in input, empty input, etc). I hope all that made sense. Any help/suggestions are welcome.

I would expect that users of the actual device are not required to use Windows 7 so it stands to reason that this can be done. Any poitners in the right direction would be greatly appreciated.

  • Deterministic floating point and .NET

    - by code2code
    How can I guarantee that floating point calculations in a .NET application (say in C#) always produce the same bit-exact result? Especially when using different versions of .NET and running on different platforms (x86 vs x86_64). Inaccuracies of floating point operations do not matter. In Java I'd use strictfp. In C/C++ and other low level languages this problem is essentially solved by accessing the FPU / SSE control registers but that's probably not possible in .NET. Even with control of the FPU control register the JIT of .NET will generate different code on different platforms. Something like HotSpot would be even worse in this case... Why do I need it? I'm thinking about writing a real-time strategy (RTS) game which heavily depends on fast floating point math together with a lock stepped simulation. Essentially I will only transmit user input across the network. This also applies to other games which implement replays by storing the user input. Not an option are: decimals (too slow) fixed point values (too slow and cumbersome when using sqrt, sin, cos, tan, atan...) update state across the network like an FPS: Sending position information for hundreds or a few thousand units is not an option Any ideas?
