  • variable being weirdly deleted

    - by calccrypto
    im having a weird problem with one variable: its not being recognized but its still printing. i would post my code, but it is massive. the basic idea is: # pseudocode def function(stuff): <do stuff> # These are the only 2 conditions if tag == 3: pka = <a string> if tag == 4: pka = <a string> print pka # (1) print pka # (2) <do stuff not modifying pka> print pka # (3) if pka == 'RSA': <do stuff> elif pka == 'DSA': <do stuff> my code will error at (2). however, it will print out (1), (2), and (3), all of which are the same. is there any general explanation of why this is happening? if my code is really needed, i will post it, but otherwise, i would rather not due to its size update: now the code will error at the if statement after (3), saying UnboundLocalError: local variable 'pka' referenced before assignment even though (1),(2),(3) just printed

  • Ruby on Rails- :symbols, @iVars and "strings" - oh my!

    - by Meltemi
    New to Rails and trying to get my head around when/why to use :symbols, @ivars , "strings" within the framework. I think I understand the differences between them conceptually only one :symbol instance per project one @ivar per instance multiple "strings" - as they are created whenever referenced (?) Feel free to correct me! The main confusion comes from understanding the rules & conventions of what Rails expects - where and WHY? I'm sure there's an "Ah ha!" moment coming but I haven't had it yet...as it seems pretty arbitrary to me (coming from C/Obj-C). -thx

  • Error with global variable in php not extending to included php file

    - by phileaton
    I have an html file that calls has a php section in the header like so: $page = basename($_SERVER['PHP_SELF']); Now further down in the html file I have a included footer like so: <?php include("footer.php"); ?> In this script I am referencing the $page variable, but it doesn't find it. I tried echoing the variable and nothing happened. When I place the basename() code in the footer.php file though, it handled it fine. I'd like to be efficient with the coding, so how can I get the footer.php file to get that $page variable? Is there a better way to do this than including the $page variable twice?

  • JavaScript's Associative Array / Object can't be read in functions

    - by Matrym
    At the very beginning of the javascript file, I have: var lbp = {}; lbp.defaults = { minLength: 40 }; I can successfully alert it afterwards, with: alert(lbp.defaults.minLength); But as soon as I put it inside a function, when I alert, I get "Undefined". What gives, and how do I avoid this? Is it absolutely necessary to pass this variable into each function, for example, by doing: function(lbp) { alert(lbp.defaults.minLength); } I would have thought that defining it first, it would attain global scope and not be required to be passed in? Thanks in advance for enlightening me :)

  • How do I set a value to the Session in asp.net on an onClick event of a normal htmlElement?

    - by William Calleja
    I need to make a Function that receives a Session Key and a Session Value and call this function on a normal HTML onClick event. When this function is called the Session variable is assigned the Key I sent with the Value I sent. So far I have this: <script runat="server" type="text/C#"> protected void setSessionValue(string key, string value) { Session[key] = value; } </script> But when I try to call if like so: onclick="setSessionValue('itemID','3345');" Its not working and giving me an error. Any help? I'm using c# and asp.net but I can't use code behind and need to work everything off the page.

  • 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.

  • 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?

  • What would be a better implementation of shared variable among subclass

    - by Churk
    So currently I have a spring unit testing application. And it requires me to get a session cookie from a foreign authentication source. Problem what that is, this authentication process is fairly expensive and time consuming, and I am trying to create a structure where I am authenticate once, by any subclass, and any subsequent subclass is created, it will reuse this session cookie without hitting the authentication process again. My problem right now is, the static cookie is null each time another subclass is created. And I been reading that using static as a global variable is a bad idea, but I couldn't think of another way to do this because of Spring framework setting things during run time and how I would set the cookie so that all other classes can use it. Another piece of information. The variable is being use, but is change able during run time. It is not a single user being signed in and used across the board. But more like a Sub1 would call login, and we have a cookie. Then multiple test will be using that login until SubX will come in and say, I am using different credential, so I need to login as something else. And repeats. Here is a outline of my code: public class Parent implements InitializingBean { protected static String BASE_URL; public static Cookie cookie; ... All default InitializingBean methods ... afterPropertiesSet() { cookie = // login process returns a cookie } } public class Sub1 extends Parent { @resource public String baseURL; @PostConstruct public void init() { // set parents with my baseURL; BASE_URL = baseURL; } public void doSomething() { // Do something with cookie, because it should have been set by parent class } } public class Sub2 extends Parent { @resource public String baseURL; @PostConstruct public void init() { // set parents with my baseURL; BASE_URL = baseURL; } public void doSomethingElse() { // Do something with cookie, because it should have been set by parent class } }

  • Adding extra data to a Variable

    - by DogPooOnYourShoe
    Right now, my code plucks out only one value using Mysql. So I thought I might aswell add each found result to a variable, however I dont know how to do this. This must be a very basic question, but I cant find a answer for it echo '<table border="1">'; echo "<tr><td><b>Surname</b></td><td><b>Title/Name</b></td><td><b>Numbers</b></td><td><b>Telephone</b></td><td><b>Edit</b></td><td><b>Del</b></td></tr>\n"; while ($row= mysql_fetch_array($result)) { $Surname = $row["Surname"]; $Title = $row["TitleName"]; $Email = $row["Email"]; $Telephone = $row["Telephone"]; $id = $row["id"]; $MooringNumbers = $row['Number']; $Assignedto['AssignedTo']; } $MooringQuery = "select * FROM mooring WHERE AssignedTo='$id'"; $MooringResult = mysql_query($MooringQuery) or die("Couldn't execute query"); while ($row1= mysql_fetch_array($MooringResult)) { $AssignedTo = $row1["AssignedTo"]; $MooringNumbers = $row1["Number"]; echo '<tr><td>' .$Surname.'</td><td>'.$Title.'</td><td>'.$MooringNumbers . '</td><td>'.$Telephone.'</td><td>' . '<a href="rlayCustomerUpdtForm.php?id='.$id.'">[EDIT]</a></td>'.'<td>'. '<a href="deleteCustomer.php?id='.$id.'">[x]</a></td>'. '</tr>'; }

    I have a macro which runs several Sql queries. One of these queries is run based off a date which in input in a msgbox within the macro (only companies after the date entered are generated).

    I have the following line of code that I use to update my personal date variable in my projects to todays current date. This line works in Ubuntu's terminal, but the Mac terminal seems to be far behind. Unfortunately, I copied this snippet from some site, so I'm not sure how it exactly works.

  • C++ Beginner - Trouble using structs and constants!

    - by Francisco P.
    Hello everyone! I am currently working on a simple Scrabble implementation for a college project. I can't get a part of it to work, though! Check this out: My board.h: http://pastebin.com/J9t8VvvB The subroutine where the error lies: //Following snippet contained in board.cpp //I believe the function is self-explanatory... //Pos is a struct containing a char, y, a int, x and an orientation, o, which is not //used in this particular case void Board::showBoard() { Pos temp; temp.o = 0; for (temp.y = 'A'; temp.y < (65 + TOTAL_COLUMNS); ++temp.y) { for (temp.x = 1; temp-x < (1 + TOTAL_ROWS); ++temp.x) { cout << _matrix[temp].getContents(); } cout << endl; } } The errors returned on compile time: http://pastebin.com/bZv7fggq How come the error states that I am trying to compare two Pos when I am comparing chars and ints? I also really can't place these other errors... Thanks for your time!

  • 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

  • Variable type for Application on Time Events [on hold]

    - by user2931226
    Been Trying to figure out how to go about setting a Variable for some Application On Time events, But still not confident to do it. These events (Macro's) get called by another Macro then they wait for 10 - 20 minutes, then they don't Run. So have read that (EarliestTime argument) should be assigned to a variable to store it other wise it looses it when other things are running Help appreciated Thanks Sub settimers() Application.OnTime TimeValue(Range("$X$9").Text), "StartBlink" Application.OnTime TimeValue(Range("$W$11").Text), "StopBlink" End Sub

  • is there a way to add a variable/property to a DOM element (eg, an element returned by a jQuery sele

    - by bt
    Hi there, I am looking for an alternative to using an object/variable in global scope -- I would like to associate key/value pairs with specific DOM elements (eg, a DIV), so that I can use them as input for logic that processes other elements (eg, child elements of said DIV). I tried something naive like: $('[foo=bar]').key='value' , and $('[foo=bar]')[key]='value', but it puked. Doing something like: var foobar = $('[foo=bar]'); foobar.key = 'value' -- works, but the new property/value only affects the new object (ie, foobar, not $('[foo=bar]')) Most likely there's something terribly basic I am overlooking. Any help is appreciated, thanks!

  • PHP => Alternative to session data?

    - by Armz
    i have a Web Application where Cookies and Session are both important. Since the Web Application is load balanced on different server, i am looking for suggestions to Alternative Store for the Session data that all server will be able to access. Some sessions could live up to severals days. The solutions that come to my mind: - Native PHP Sessions (this is the one i want to stop using) - MySQL Database - Serialize and write to a file (i want to avoid this, for performances) - Memcache (however it could become very big or older data getting knocked out) Thanks in advance!
