  • Java: global values inside a class?

    - by HH
    I want less methods. I want a common global TestClass from which I could use any of its value inside the class. import java.util.*; import java.io.*; public class TestClass { TestClass(String hello){ String hallo = hello; String halloSecond = "Saluto!"; } public static void main(String[] args) { TestClass test = new TestClass("Tjena!"); System.out.println("I want "Tjena!": " + test.hallo); TestClass testSecond = new TestClass("1"); System.out.println("I want Saluto!:" + test.halloSecond); System.out.println("I want Saluto!:" + testSecond.halloSecond); } }

  • C++ - 3 possible values in Variable?

    - by noryb009
    I need to store a 30 letter combination, but each letter can only be "0", "1" or "2". When I use sizeof(myString), it returns 32. I want to use this 30 letter combination to access a row of an array, so I'm wondering if it is possible to use a 3 value bool of some sort to store 1 of 3 values in.

  • C++ reference variable again!!!

    - by kumar_m_kiran
    Hi All, I think most would be surprised about the topic again, However I am referring to a book "C++ Common Knowledge: Essential Intermediate Programming" written by "Stephen C. Dewhurst". In the book, he quotes a particular sentence (in section under Item 5. References Are Aliases, Not Pointers), which is as below A reference is an alias for an object that already exists prior to the initialization of the reference. Once a reference is initialized to refer to a particular object, it cannot later be made to refer to a different object; a reference is bound to its initializer for its whole lifetime Can anyone please explain the context of "cannot later be made to refer to a different object" Below code works for me, #include <iostream> using namespace std; int main(int argc, char *argv[]) { int i = 100; int& ref = i; cout<<ref<<endl; int k = 2000; ref = k; cout<<ref<<endl; return 0; } Here I am referring the variable ref to both i and j variable. And the code works perfectly fine. Am I missing something? I have used SUSE10 64bit linux for testing my sample program. Thanks for your input in advance.

  • How to give new life into a five years old, simple but reliable PHP form?

    - by Sam
    Hi all. I have a script in php 5.2. I want to use a simple form. I found something a programmer made for me about 5 years ago. When I use it, PHP outputs an error now unless I set register_long_arrays = On, then it works fine. On the PHP website, however, it says: Warning This feature has been DEPRECATED as of PHP 5.3.0. Relying on this feature is highly discouraged. It's recommended to turn them off, for performance reasons. Instead, use the superglobal arrays, like $_GET. Should I listen to PHP's warning, or just enable the option and keep using my old form happily? If the former, then how/where do I change this simple form, so it does not rely on the deprecated setting? Your answer is much appreciated. form.htm <html><body> <form method="POST" action="form_sent.php"> ... </form> </body></html> form_sent.php <html><body> <?php $email = $HTTP_POST_VARS[email]; $mailto = "[email protected]"; $mailsubj = "A Form was Sent from Website!"; $mailhead = "From: $email\n"; reset ($HTTP_POST_VARS); $mailbody = "Values submitted from web site form:\n"; while (list($key, $val) = each ($HTTP_POST_VARS)){$mailbody .= "$key : $val\n";} if (!eregi("\n",$HTTP_POST_VARS[email])) { mail($mailto, $mailsubj, $mailbody, $mailhead); } ?> <b>Form Sent. Thank you.</b> </body></html>

  • Bash Color Variable Output

    - by drewrockshard
    I've got a variable, let's say $x and it holds the value of website.com. I want to be able to call the variable and apply shell color to it like so: echo -e '\033[1;32m$x:\033[0m'; The problem is not the color, however, it's how the script it interpretting the output. So the output I'm getting is: $x: I need the output to obviously be the string in the variable, and not the variable name. Is there any way around this issue?

  • Static variable for optimization

    - by keithjgrant
    I'm wondering if I can use a static variable for optimization: public function Bar() { static $i = moderatelyExpensiveFunctionCall(); if ($i) { return something(); } else { return somethingElse(); } } I know that once $i is initialized, it won't be changed by by that line of code on successive calls to Bar(). I assume this means that moderatelyExpensiveFunctionCall() won't be evaluated every time I call, but I'd like to know for certain. Once PHP sees a static variable that has been initialized, does it skip over that line of code? In other words, is this going to optimize my execution time if I make a lot of calls to Bar(), or am I wasting my time?

  • Variable not accessible within and if statment

    - by Chris
    I have a variable which holds a score for a game. My variable is accessible and correct outside of an if statement but not inside as shown below cout << score << endl; //works if(!justFinished){ cout << score << endl; // doesn't work prints a large negative number endTime = time(NULL); ifstream highscoreFile; highscoreFile.open("highscores.txt"); if(highscoreFile.good()){ highscoreFile.close(); }else{ std::ofstream outfile ("highscores.txt"); cout << score << endl; outfile << score << std::endl; outfile.close(); } justFinished = true; } cout << score << endl;//works

  • converting a form from text to textarea

    - by David Cook
    I have a form created to pull PHP values into my database. I created the form with all type="text" constructions. What follows is the code that used to set up the input of data and confirmed that it is functional. <label>About Me: <input type="text" name="BIO_info"/></label> I converted the input to a textarea and adjusted some parameters for proper display. Unfortunately, it has broken the ability for the script to function. What follows is the code I wrote to convert and store from a text area input. <label for="BIO_info" style=" margin-bottom: 500px; margin-top: 2000px; ">About Me: <textarea name="BIO_info" rows="20" cols="60" style="resize: none; overflow-y: hidden;vertical-align:middle;"></textarea> <p> I would appreciate any suggestions.

  • Jquery Accordion and multiple slideshows

    - by Dipesh Parmar
    I've been using a lot of slideshows recently on my sites and one thing thats puzzled me is using more than one slideshow per page. I'm currently working on my own site, experimenting with Jquery Accordion. I've managed to adopt a very simple javascript slideshow, see below: http://dvpwebdesign.com/test/accordion/blank.html However i'm unable to either incorporate or use a different multiple slideshow plugin. I dont need slideshow navigation, so the The Cycle plugin works really well and i know you can use multiple slideshows. But if i either use Cycle alongside the current javascript slideshow, or only use the Cycle slideshow to avoid any possible conflict, the Accordion menu stops working. I just cant see what i am doing wrong, can anyone help?

  • Symfony: Pass an object from another module to a form

    - by djcloud23
    I have a symfony project and I have one model, which for this example I will name Boat. From the Boat's showSuccess page, I would like to make a link to another model's form page. For this example we will call it Ticket. When they click on the link, I would like for the Boat object to be passed to the Ticket form because I have to display some of that specific Boat's fields (title, price, etc) on the Ticket form page (newSuccess.php). I guess my question is, how do I pass an object (as a variable) to another model's "new" form page. I have looked everywhere and I can't seem to find an answer that works for me. Thank you!

  • PHP variable equals true no matter what the value, even 0

    - by kaigoh
    This is the var_dump: object(stdClass)#27 (8) { ["SETTING_ID"]=> string(2) "25" ["SETTING_SOURCE"]=> string(2) "XV" ["SETTING_FLEET"]=> string(3) "313" ["SETTING_EXAM"]=> string(1) "A" ["SETTING_HIDE"]=> string(1) "0" ["SETTING_THRESHOLD"]=> string(1) "0" ["SETTING_COUNT"]=> string(8) "POSITIVE" ["SETTING_USAGE"]=> string(7) "MILEAGE" } The variable I am testing is SETTING_HIDE. This is being pulled from MySQL using the Code igniter framework. I don't know if it is just me being thick after a rather long day at work or what, but no matter what value the variable holds, any if statement made against it returns true, even when typecast as a boolean or a direct string comparison, ie. == "0" or == "1". Anyone with a fresh pair of eyes care to make me feel silly!?! :) Just to clarify: Have tried the following: if($examSetting->SETTING_HIDE == "1") { $showOnABC = "checked=\"checked\""; } if((bool)$examSetting->SETTING_HIDE) { $showOnABC = "checked=\"checked\""; } if($examSetting->SETTING_COUNT == "POSITIVE") further on in my code works perfectly.

  • using key/value collection in session

    - by jumpdart
    Question: What is a good datatype to keep in session for a large collection of keys and values to frequently reference and update? Application: Updating an old .NET web app with a million pages and grids to have all the grids maintain their sort. They currently access helper code to format themselves graphically on load and on sort. I figured I could add to that code to check for a key based on the page and grid id in a collection in session to see if it has a previous expression on load. and the on sort update/add its appropriate item in the collection. Thoughts? Dictionary vs NameValueCollection

  • Preventing entire JOINed MYSQL query from failing when one field is missing within a WHERE clause

    - by filip o
    I am doing a couple of joins with a variable in the WHERE clause. I'm not sure if I am doing everything as efficiently as I could, or even using the best practices but my issue is that half my tables have data for when tableC.type=500, and the other half don't resulting in the entire query failing. SELECT tableA.value1 , tableB.value2, tableC.value3 FROM tableA JOIN tableB ON tableB.id=tableA.id JOIN tableC ON tableC.id=tableB.id WHERE tableA.category=$var && tableC.type=500; What I would like to happen is to still get tableA.value1 and tableB.value2 even if there is no field in tableC with a type=500. any thoughts? i'm totally stumped as how to approach this...

  • How can I use a value of JSP in Javascript code?

    - by novellino
    Hello, I have a list of elements, each of them appeared in my page through jsp. So I have this: <div id="title"><%= list.get(ind).getTitle() %></div> When I display the elements, as this tag is in for loop, I get everything right. Now I what to place a button for deleting each of this elements. What I have done is: <input type="submit" name="submit" onclick="deleteNewsFunction();" id="submit_btn"/> In the deleteNewsFunction() I just want to print the data. <script> function deleteNewsFunction(){ var item = $('#title').val(); alert(item); } </script> The problem is that the title var gets always the first item even if I am clicking on the button of the second item. I was thinking that maybe a solution is to add the "list.get(ind).getTitle()" as a parameter in the function like deleteNewsFunction(<%=list.get(ind).getTitle()%) but then it did not work at all. Does anyone know how to help me? Thanks a lot!

  • DOS Batch file - Copy file based on filename elements

    - by user1848356
    I need to sort alot of files based on their filename. I would like to use a batch file to do it. I do know what I want but I am not sure of the correct syntax. Example of filenames I work with: (They are all in the same directory originally) 2012_W34_Sales_Store001.pdf 2012_W34_Sales_Store002.pdf 2012_W34_Sales_Store003.pdf 2012_November_Sales_Store001.pdf 2012_November_Sales_Store002.pdf 2012_November_Sales_Store003.pdf I would like to extract the information that are located between the "_" signs and put them into a different variable each time. The lenght of the informations contained between the _ signs will be different everytime. Example: var1="2012" var2="W34" (or November) var3="Sales" var4="001" If I am able to do this, I could then copy the files to the appropriate directory using move %var1%_%var2%_%var3%_%var4%.pdf z:\%var3%\%var4%\%var1%\%var2% It would need to loop because I have Store001 to Store050. Also, there are not only Sales report, many others are available. I hope I am clear. Please help me realize this batchfile!

  • Passing CMD Results to Variable in a Batch File

    - by TripleNad
    I am trying to install an application and a group of services using PSTools, but I want to take into account that the computer I am trying to connect to may be turned off or on a different network, which is not reachable from the internal network. Basically if the machine is not able to be accessed through the admin share, this is the message that I am getting: Couldn't access MachineName: The network path was not found. Make sure that the default admin$ share is enabled on MachineName. This is the syntax I am using to try to capture the "Error Message" and then report back that if installation was successful or not (depending on if it can contact the machine) @echo off set /p name=What is the machine name?: psexec.exe \\\%name% -u *useraccount* -p *password* \\\ServerName\installation.bat FOR /F "tokens=*" %%A IN ('COMMAND ^| FIND "Couldn't access"') DO SET Error=%%A If "%Error%"=="Couldn't access" ECHO Installation Failed. Else ECHO Installtion complete. Pause exit Currently it hangs right at the point it's defining the Error Variable. Can't quite figure out what I am going wrong here.

  • Homework - C# - Creating an object instance with a button click

    - by Erica
    I'm new to learning Windows Programming with C#. My current assignment is to create a very simple bank account program: The user enters the accountholder name, account number and beginning balance, then presses a "Continue" button to work with that account by making deposits and withdrawals. I wrote a separate "BankAccount" class with the required data members and methods. I've put the code for the creation of the BankAccount object in the Continue button click event BankAccount currentAccount = new BankAccount(acctName, acctNum, beginningBalance); But that seems to make it local to that method only, and currentAccount is not recognized when I'm programming the click event for the "Record Transactions" (deposits and withdrawals) button. How and where should the creation of the BankAccount object be coded in order for it to be created when the "Continue" button is clicked and also recognized in the "Record Transactions" button click event? Please let me know if any clarification is needed, or if you need to see part or all of my code.

  • Oracle 10g multiple DELETE statements

    - by bmw0128
    I'm building a dml file that first deletes records that may be in the table, then inserts records. Example: DELETE from foo where field1='bar'; DELETE from foo where fields1='bazz'; INSERT ALL INTO foo(field1, field2) values ('bar', 'x') INTO foo(field1, field2) values ('bazz', 'y') SELECT * from DUAL; When I run the insert statement by itself, it runs fine. When I run the deletes, only the last delete runs. Also, it seems to be necessary to end the multiple insert with the select, is that so? If so, why is that necessary? In the past, when using MySQL, I could just list multiple delete and insert statements, all individually ending with a semicolon, and it would run fine.

  • Saving Data to Registry on Windows 7

    - by Jim Fell
    I heard that Windows 7 restricts access to its registry, so that applications cannot write directly to it. Is this so? I am developing an application in C#, and I would like to be able to save things such as port settings, last file used, etc. between sessions. Is the registry still a good option, or is there another preferred means of doing this now? Thanks.
