• Access JavaScript variables with Selenium IDE

  - by kRON

  I'm wondering if it's possible to access page JavaScript variables with Selenium. I have an application that's using a variable attached to the window object. It has a global scope and I can access it either with window._myvar, window['_myvar'], _myvar, this['_myvar'], this._myvar depending on the context. So I tried to get Selenium to echo it. As far as I understand, in Selenium IDE the context in which everything runs is selenium. I tried doing this.browserbot.getCurrentWindow()._myvar, this.browserbot.getCurrentWindow()[_myvar] to no avail. I get bumped with the following error Unexpected Exception: message -> eval(match[1]) is undefined. Anyone managed to access their page's JavaScript?

• Python regular expressions matching variables to end of line

  - by None

  When you use variables (is that the correct word?) in python regular expressions like this: "blah (?P\w+)" ("value" would be the variable), how could you make the variable's value be the text after "blah " to the end of the line or to a certain character not paying any attention to the actual content of the variable. For example, this is pseudo-code for what I want: >>> import re >>> p = re.compile("say (?P<value>continue_until_text_after_assignment_is_recognized) endsay") >>> m = p.match("say Hello hi yo endsay") >>> m.group('value') 'Hello hi yo' Note: The title is probably not understandable. That is because I didn't know how to say it. Sorry if I caused any confusion.

• Memory allocation in case of static variables

  - by eSKay

  I am always confused about static variables, and the way memory allocation happens for them. For example: int a = 1; const int b = 2; static const int c = 3; int foo(int &arg){ arg++; return arg; } How is the memory allocated for a,b and c? What is the difference (in terms of memory) if I call foo(a), foo(b) and foo(c)?

• How to use variables with regex?

  - by dontoo

  This is the input string: 23x^45*y or 2x^2 or y^4*x^3. I am matching ^[0-9]+ after letter x. In other words I am matching x followed by ^ followed by numbers. Problem is that I don't know that I am matching x, it could be any letter that I stored as variable in my char array. For example: foreach (char cEle in myarray) // cEle is letter in char array x, y, z, ... { match CEle in regex(input) //PSEUDOCODE } I am new to regex and I new that this can be done if I define regex variables, but I don't know how.

• Prepared statement help, Number of variables doesn't match number of parameters in prepared statement

  - by Sam Gabriel

  I'm getting this error : Number of variables doesn't match number of parameters in prepared statement every time I run this code: $dbh = new mysqli("localhost", "***", "***", "pics"); $stmt = $dbh->prepare("INSERT INTO comments (username, picture, comment) VALUES (?, ?, ?)"); $stmt->bind_Param('s', $username); $stmt->bind_Param('d', $picture); $stmt->bind_Param('s', $comment); $username=$_SESSION['username']; $picture=$_GET['id']; $comment=$_POST['comment']; $stmt->execute(); What's the problem?

• classes and static variables in shared libraries

  - by abel

  I am trying to write something in c++ with an architecture like: App -- Core (.so) <-- Plugins (.so's) for linux, mac and windows. The Core is implicitly linked to App and Plugins are explicitly linked with dlopen/LoadLibrary to App. The problem I have: static variables in Core are duplicated at run-time -- Plugins and App have different copys of them. at least on mac, when a Plugin returns a pointer to App, dynamic casting that pointer in App always result in NULL. Can anyone give me some explanations and instructions for different platforms please? I know this may seem lazy to ask them all here but I really cannot find a systematic answer to this question.

• Environment variables get lost between MSBuild projects

  - by DotNetter

  Hi, I have a .NET solution containing following projects: web application (WAP) web deployment (WDP, .wdproj) wix setup (WIX, .wixproj) In the WDP I've used a custom MSBuild task (SetEnvVar) to set some env. variables for further use in the build process. After setting them I can use them without prob. in the WDP but in the WIX they are empty/undefined. The strange thing is that when I reference those env. vars in the WIX files (by using properties in .wxs or preproc vars in .wxi) I get the values as expected. Do you have any idea why the env. vars get lost/are undefined in .wixproj? By the way the (solution) build process is triggered from inside VS 2010.

• How to Split and strip into multiple variables?

  - by Khou

  How to Split and strip X string values into separate variables? X has string value of itemA=myvalue&itemB=anothervalue&itemC=andanother I have 3 strings (var1,var2,var3) to hold the values of the stripped values. Find in string X "itemA=" copy everything after "=" character until "&" character OR if no "&" character is found copy until end of string (store this value into var1) Find in string X "itemB=" copy everything after "=" character until "&" character OR if no "&" character is found copy until end of string (store this value into var2) Find in string X "itemB=" copy everything after "=" character until "&" character OR if no "&" character is found copy until end of string (store this value into var3)

• Allowing optional variables with Rewrite Cond

  - by James Doc

  I currently have the following code: RewriteCond %{REQUEST_URI} !assets/ RewriteCond %{REQUEST_URI} !uploads/ RewriteRule ^([a-z|0-9_&;=-]+)/([a-z|0-9_&;=-]+) index.php?method=$1&value=$2 [NC,L] This works perfectly to redirect 'page/home' to 'index.php?method=page&value=home. However at some points I need to add an extra variable or two to the query string such as 'admin/useraccounts/mod/2'. When I simply tack on bits to the end of the rewrite rule it works if all the variables are 'page/home/rand/rand' or 'admin/useraccounts/mod/2', but if anything is missing such as 'page/home' I get a 404. What am I doing wrong? Many thanks.

• (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

• SELECT TOP N With Two Variables

  - by Ricardo Deano

  Hello all. It's Tuesday morning and I am being thick as (I'm blaming my daughter waking up early this morning!) I have the following example in a SQL table Cust Group Sales A 1 15 A 1 10 A 1 5 A 2 15 A 2 10 A 2 5 B 1 15 B 1 10 B 1 5 B 2 15 B 2 10 B 2 5 What I would like to show is the top 2 products per customer, per group sorted descending by Sales i.e. Cust Group Sales A 1 15 A 1 10 A 2 15 A 2 10 B 1 15 B 1 10 B 2 15 B 2 10 I'm assuming I need to declare two variables, Cust and Group, I'm just not sure how to complete this in one fell swoop. Apologies for the thick question...no excuse. Thanks for any help.

• Why aren't unsigned OpenMP index variables allowed?

  - by Moe

  I have a loop in my C++/OpenMP code that looks like this: #pragma omp parallel for for(unsigned int i=0; i<count; i++) { // do stuff } When I compile it (with Visual Studio 2005) I get the following error: error C3016: 'i' : index variable in OpenMP 'for' statement must have signed integral type I understand that the error occurs because i is unsigned instead of signed, and changing i to be signed removed this error. What I want to know is why is this an error? Why aren't unsigned index variables allowed? Looking at the MSDN page for this error gives me no clues.

• Why are $_POST variables getting escaped in PHP?

  - by George Edison

  When my PHP script receives data from an AJAX POST request, the $_POST variables are escaped. The really strange thing is that this only happens on my production server (running PHP 5.2.12 on Linux) and not on my local server (running PHP 5.3.1 on Windows). Here is the AJAX code: var pageRequest = false; if(window.XMLHttpRequest) pageRequest = new XMLHttpRequest(); else if(window.ActiveXObject) pageRequest = new ActiveXObject("Microsoft.XMLHTTP"); pageRequest.onreadystatechange = function() { } var q_str = 'data=' + " ' "; pageRequest.open('POST','unnamed_page.php',true); pageRequest.setRequestHeader("Content-type", "application/x-www-form-urlencoded"); pageRequest.setRequestHeader("Content-length", q_str.length); pageRequest.setRequestHeader("Connection", "close"); pageRequest.send(q_str); Is there any reason this is happening? And how should I fix this so that it works on both servers?

• Using PHP variables inside SQL statements?

  - by Homer

  For some reason I can't pass a var inside a mysql statement. I have a function that can be used for multiple tables. So instead of repeating the code I want to change the table that is selected from like so, function show_all_records($table_name) { mysql_query("SELECT * FROM $table_name"); etc, etc... } And to call the function I use show_all_records("some_table") or show_all_records("some_other_table") depending on which table I want to select from at the moment. But it's not working, is this because variables can't be passed through mysql statements?

• Thread Local Storage and local method variables

  - by miguel

  In c#, each thread has its own stack space. If this is the case, why is the following code not thread-safe? (It is stated that this code is thread-safe on this post: Locking in C# class Foo { private int count = 0; public void TrySomething() { count++; } } As count is an int (stack variable), surely this value would be isolated to an individual thread, on its own stack, and therefore thread-safe? I am probably missing something here, but I dont understand what is actually in Thread Local Storage if not stack-based variables for the thread?

• importing CELERY* environment variables in django settings.py causes celeryd not to start

  - by Taras

  I just spent 2 hours trying to figure out why django celery stopped working. Celery would being to start, but would stop short of printing out the configuration items, implying that it wasn't starting correct. The log would only contain The celery.decorators module along with the magic keyword arguments, are deprecated, and will be removed in version 3.0. Please use the celery.task module instead of celery.decorators, and the task.request should be used instead of the magic keyword arguments: from celery.task import task See http://bit.ly/celery22major for more information. """)) It turns out that some celery env variables that I was importing to try and fix a different problem were causing celery not to start correctly: from celery.tests.config import CELERY_QUEUES, CELERY_DEFAULT_QUEUE, CELERY_DEFAULT_ROUTING_KEY Even though I wasn't using them anywhere. Does anyone know what was happening?

• Python try/except: Showing the cause of the error after displaying my variables

  - by NealWalters

  I'm not even sure what the right words are to search for. I want to display parts of the error object in an except block (similar to the err object in VBScript, which has Err.Number and Err.Description). For example, I want to show the values of my variables, then show the exact error. Clearly, I am causing a divided-by-zero error below, but how can I print that fact? try: x = 0 y = 1 z = y / x z = z + 1 print "z=%d" % (z) except: print "Values at Exception: x=%d y=%d " % (x,y) print "The error was on line ..." print "The reason for the error was ..."

• Loop colours from variables for graphics.py [Python 3.2]

  - by user1056548

  I am creating a graphics program that draws 100 x 100 squares next to each other depending on the user-specified grid size. The user also inputs 4 colours for the squares to be coloured (e.g. if they enter red,green,blue,yellow the squares will be coloured in that order, repeating the colours). Is it possible to loop the colours from the variables the user has given? Here is what I have so far: def main(): print ("Please enter four comma seperated colours e.g.: 'red,green,blue,yellow'\n\ Allowed colours are: red, green, blue, yellow and cyan") col1, col2, col3, col4 = input("Enter your four colours: ").split(',') win = GraphWin ("Squares", 500, 500) colours = [col1, col2, col3, col4] drawSquare (win, col1, col2, col3, col4, colours) win.getMouse() win.close() def drawSquare(win, col1, col2, col3, col4, colours): for i in range (4): for j in range (len(colours)): colour = colours[j] x = 50 + (i * 50) circle = Circle (Point (x,50), 20) circle.setFill(colour) circle.draw(win) I think I should be using a list in some way, but can't work out exactly how to do it. Can anybody help?

• Creating Dynamic variables from json response

  - by c0mrade

  My JSON response looks like this : {"sample":[{"id":"2","name":"branch name"},{"id":"3","name":"branch name 2"}]} My function looks like this : function getJSONObjects(){ $.getJSON("http://localhost/api/branches", function(data){ $.each(data.sample, function(i,item){ var loc = "branch"; eval("var " + loc + item.id + "=123;"); alert(loc + item.id); }); }); } The idea is to create branch + id object so I can do something with it(create marker on a map), so I tried to assign it any value to see if this was working. I wanted both branch2 and branch3 to alert 123 so I have something to start with. But currently this alerts branch2 and branch3 instead of 123. I have little experience with creating dynamic variables/objects can someone tell me what I'm doing wrong or maybe another approach towards solving this?

• Inverse relationship of two variables

  - by Jam

  this one is maybe pretty stupid.. Or I am just exhausted or something, but I just cant seem to solve it.. Problem : two variables X and Y, value of Y is dependent on value of X. X can have values ranging from some value to some value (lets say from 0 to 250) and y can have different values (lets say from 0.1 to 1.0 or something..) - but it is inverse relatonship (what I mean is: if value of X is e.g. 250, then value of Y would be 0.1 and when X decreases up to 0, value of Y raises up to 1.0.. So how should I do it? lets say I have function: -- double computeValue (double X) { /computation/ return Y; } Also, is there some easy way to somehow make the scaling of the function not so linear? - For example when X raises, Y decreases slower at first but then more rapidly in the end.. (rly dont know how to say it but I hope you guys got it) Thanks in advance for this stupid question :/

• Using member variables inherited from a templated base class (C++)

  - by Aaron Becker

  I'm trying to use member variables of a templated base class in a derived class, as in this example: template <class dtype> struct A { int x; }; template <class dtype> struct B : public A<dtype> { void test() { int id1 = this->x; // always works int id2 = A<dtype>::x; // always works int id3 = B::x; // always works int id4 = x; // fails in gcc & clang, works in icc and xlc } }; gcc and clang are both very picky about using this variable, and require either an explicit scope or the explicit use of "this". With some other compilers (xlc and icc), things work as I would expect. Is this a case of xlc and icc allowing code that's not standard, or a bug in gcc and clang?

• How can I create variable variables in ActionScript

It seems that I can't create variable variables in compiled languages.

• Passing variables to functions in Python

  Im writing test scripts in python for selenium web testing. How do I pass parameters through a python function to call in a later function? I first have a login test function. Then I have a new user registration function. Im trying to pass the Username and Password I use in the registration function to the testLogin function that I call inside the testRegister function. This is my python code: userName = "admin" password = "admin" #pass username and password variables to this function def testLogin(userName,password): browser = webdriver.Firefox() browser.get("http://url/login") element = browser.find_element_by_name("userName") element.send_keys(userName) element = browser.find_element_by_name("userPassword") element.send_keys(password) element.send_keys(Keys.RETURN) browser.close() # test registration def testRegister(): browser = webdriver.Firefox() browser.get("http://url/register") #new username variable newUserName = "test" element = browser.find_element_by_name("regUser") element.send_keys(newUserName) #new password variable newUserPassword = "test" element = browser.find_element_by_name("regPassword") element.send_keys(newUserPassword) # #now test if user is registered, I want to call testLogin with the test user name and pw. testLogin(newUserName,newUserPassword) browser.close()

• Setting package-wide variables during python setup.py install

  - by Morgoth

  Is there a way that when a user types python setup.py install to install a Python package, setup.py can be made to set specific variables at the base of the pacakge? A common example would be to basically set mypackage.__revision__ to be the svn revision of the checkout if one is working from svn. Another example case would be if the user can choose a global option, so that the option mypackage.__option__ be set according to a flag passed to setup.py, e.g. python setup.py install --set-flag=10 Then when using the package, mypackage.__option__ would equal 10.
