  • Removing Unused (Unreferenced) Static Global Variable Constants in C++

    - by Synetech inc.
    Hi, I have a header file with a few common constants like names and stuff that are automatically included in each project (an example follows). The thing is that they are included in the compiled binary (EXE) whether they are used (referenced) or not. If I use DEFINEs instead, then naturally they are not included if they are not used, but of course consts are better than defines so… I tried Googling it, but the closest thing I could find was a question right here on SO that did not quite help. Matters of i18n aside, how can I keep the ones that are not used out of the binary, while still keeping it easy to use like this? Thanks. //COMMON.H: static const CString s_Company _T("Acme inc."); //etc. static const CString s_Digits _T("0123456789"); //TEST.CPP: #include common.h int main() { AfxMessageBox(s_Company); } //s_Company should be in the final EXE, but s_Digits should not be, but is

  • Monitor multiple variable amounts of processes' start and exit

    - by ron975
    I need some code to monitor the start and exit of processes. For example, assume I have a config file with 3 processe names, lets say, foo.exe, bar.exe and abc.exe. How I imagine this be done would be to create 3 threads and somehow listen to each process individually with a timer in each thread, and then do something afterwards. However, I would need to dynamically create threads and timers, as the config file is meant to be modifiable. I can work with VB.NET or C# Code. Thanks.

  • Having access to a private variable from other classes in Java

    - by Crystal
    If I want to create a form that adds people to a List, how do I have access to that List from another class? Where would I define that List so other classes can access the members, the size, etc? For example, if I have Class Foo that has the GUI for my form, along with buttons to add and remove people to the List, it would make sense to me to declare the List as a private instance variable of Class Foo. But then if I have another class, Class Bar, how does it get the values that are currently in that List to update some other graphical components? Or is that the wrong place to declare the List in general? Thanks.

  • RSpec "undefined local variable or method `user'"

    - by Justin
    I have the following test written in RSpec: describe '#create' do ... it 'redirects users to profile page' do response.should redirect_to user_path(user) end ... ... And the following in my UsersController: def create @user = User.new(params[:user]) if @user.save redirect_to user_path(@user) end end Does anyone know why this is returning the following error: NameError: undefined local variable or method 'user' I also tried changing this to be root_url in both cases instead of user_path(user) and it gave a different error saying: Expected response to be a <:redirect>, but was <200> Does anyone know what the issue might be? I have double-checked my code and have seen similar questions posted online, but haven't been able to find a solution. Thanks in advance for any help!

  • Java : Using parent class method to access child class variable

    - by Jayant
    I have the following scenario : public class A { private int x = 5; public void print() { System.out.println(x); } } public class B extends A { private int x = 10; /*public void print() { System.out.println(x); }*/ public static void main(String[] args) { B b = new B(); b.print(); } } On executing the code, the output is : 5. How to access the child class(B's) variable(x) via the parent class method? Could this be done without overriding the print() method (i.e. uncommenting it in B)? [This is important because on overriding we will have to rewrite the whole code for the print() method again]

  • How to assign variable dynamically to php list function

    - by ravisoni
    What I am doing that I want to generate a list based on how many items are in an array, so I have counted the items and loop over them, create a number based var and construct a string $var which contains $a1,$a2.... and assigns the $var to list list($var) and tried to access $a1 but it gives me the error "Undefined variable: a1" Is there any other way to do it?

  • Putting a variable inside a string (python)

    Hi I am quite new to python and this is probably quite a basic question but the help would be much appreciated. I would like to put an int within a string. This is what I am doing at the moment.. end = smooth(data,window_len=40) plot.plot(time[0:len(end)],end) plot.savefig('hanning(40).pdf') #problem line I have to run the program for several different numbers instead of the two 40's. So I'd like to do a loop but inserting the variable like this doesn't work: plot.savefig('hanning',num,'.pdf') Thanks!

  • Path Inclusion/Global variable not working?

    - by Dan LaManna
    Simply put, my config file includes my database class, and the config file has in it: global $db; $db = new database(DB_HOST, DB_NAME, DB_USER, DB_PASS); That file is root/config.php Moving on to root/functions/func.newpage.php doesn't have any includes/requires, and uses $db-classfunction since the file I'm working with: root/newpage.php - requires the config file, as well as func.newpage.php. However I still come up with: Undefined variable db. Anything you guys are seeing I'm not? Thanks! Let me know if more details are needed.

  • PHP Undefined index - Occuring when the variable has a value in it

    - by Adam
    I have the following code that is being used to successfully upload images: $fileName = $_FILES['file']['name']; $fileSize = $_FILES['file']['size']; $fileType = $_FILES['file']['type']; $fileTmp = $_FILES['file']['tmp_name']; list($origWidth, $origHeight) = getimagesize($fileTmp); The catch is I'm getting an 'Undefined index' on each line. I have print_r($_FILES) just before this code and each array variable exists and I've echo out varibles like $fileName and can see each has a value. Also I have put this before this code block and it makes no difference: $fileName = $fileSize = $fileType = $fileTmp = ''; Any suggestions how I can ensure these variables are defined? thankyou

  • Using an environment variable set to a path value: the system cannot find the path specified for %OPENCV_DIR%

    - by dumbledad
    I'm trying to set an environment variable to point to the directory into which I have extracted the latest version of OpenCV, following the instructions in OpenCV's Installation in Windows tutorial. Here's my elevated command line listing. C:\>cd C:\OpenCV2.4.6\build\x64\vc11 C:\OpenCV2.4.6\build\x64\vc11>cd ../../../.. C:\>setx -m OPENCV_DIR C:\OpenCV2.4.6\build\x64\vc11 SUCCESS: Specified value was saved. C:\>cd %OPENCV_DIR% The system cannot find the path specified. C:\>echo %OPENCV_DIR% %OPENCV_DIR% Firstly I change directory to C:\OpenCV2.4.6\build\x64\vc11 to ensure that it exists. After that is successful I change directory back to the root of the C drive. Then I use setx to make OPENCV_DIR a system wide environment variable with value the C:\OpenCV2.4.6\build\x64\vc11 path I verified in step 1. Noting the success of setx in the previous step I now change directory using the new environment variable. But it fails with the message The system cannot find the path specified. If I try to echo the value of the OPENCV_DIR environment variable it appears not to be set. Looking in the control panel the OPENCV_DIR environment variable looks correctly set: What's wrong? Why is the variable not working? Am I evoking it incorrectly when I use it to change directory or echo its value?

  • PHP, javascript, single quote problems with IE when passing variable from ajax post to javascript fu

    - by Mattis
    Hi! I have been trying to get this to work for a while, and I suspect there's an easy solution that I just can't find. My head feels like jelly and I would really appreciate any help. My main page.php makes a .post() to backend.php and fetches a list of cities which it echoes in the form of: <li onclick="script('$data');">$data</li> The list is fetched and put onto the page via .html(). My problem occurs when $data has a single quote in it. backend.php passes the variable just fine to page.php but when i run html() it throws a javascript error (in IE, not FF obviously); ')' is expected IE parses the single quote and messes up the script()-call. I've been trying to rebuild the echoed string in different ways, escaping the 's on the php side and/or on the javascript side - but in vain. Do I have to review the script in total? page.php $.post("backend.php", {q: ""+str+""}, function(data) { if(data.length >0) { $('#results').html(data); } backend.php while ($row = $q->fetch()) { $city = $row['City']; // $city = addslashes($row['City']); // $city = str_replace("'","&#39;",$row['City']); echo "<li onclick=\"script('$city');\">".$city."</li>"; }

  • How to update a uniform variable in GLSL

    Hi All, I am trying to get update the eye position in my shader from my appliaction but I keep getting error 1281 when I attempt this. I have no problems after the initialization just when i subsequently try to update the values. Here is my code: void GraphicsObject::SendShadersDDS(char vertFile [], char fragFile [], char filename []) { char *vs = NULL,*fs = NULL; vert = glCreateShader(GL_VERTEX_SHADER); frag = glCreateShader(GL_FRAGMENT_SHADER); vs = textFileRead(vertFile); fs = textFileRead(fragFile); const char * ff = fs; const char * vv = vs; glShaderSource(vert, 1, &vv, NULL); glShaderSource(frag, 1, &ff, NULL); free(vs); free(fs); glCompileShader(vert); glCompileShader(frag); program = glCreateProgram(); glAttachShader(program, frag); glAttachShader(program, vert); glLinkProgram(program); glUseProgram(program); LoadCubeTexture(filename, compressedTexture); GLint location = glGetUniformLocation(program, "tex"); glUniform1i(location, 0); glActiveTexture(GL_TEXTURE0); EyePos = glGetUniformLocation(program, "EyePosition"); glUniform4f(EyePos, EyePosition.X(),EyePosition.Y(), EyePosition.Z(), 1.0); DWORD bob = glGetError(); //All is fine here glEnable(GL_DEPTH_TEST); } And here's the function I call to update the eye position: void GraphicsObject::UpdateEyePosition(Vector3d& eyePosition){ glUniform4f(EyePos, eyePosition.X(),eyePosition.Y(), eyePosition.Z(), 1.0); DWORD bob = glGetError(); //bob equals 1281 after this call } I've tried a few ways now of updating the variable and this is the latest incarnation, thanks for viewing, all comments welcome.

  • Store comparison in variable (or execute comparison when it's given as an string)

    - by BorrajaX
    Hello everyone. I'd like to know if the super-powerful python allows to store a comparison in a variable or, if not, if it's possible calling/executing a comparison when given as an string ("==" or "!=") I want to allow the users of my program the chance of giving a comparison in an string. For instance, let's say I have a list of... "products" and the user wants to select the products whose manufacturer is "foo". He could would input something like: Product.manufacturer == "foo" and if the user wants the products whose manufacturer is not "bar" he would input Product.manufacturer != "bar" If the user inputs that line as an string, I create a tree with an structure like: != / \ manufacturer bar I'd like to allow that comparison to run properly, but I don't know how to make it happen if != is an string. The "manufacturer" field is a property, so I can properly get it from the Product class and store it (as a property) in the leaf, and well... "bar" is just an string. I'd like to know if I can something similar to what I do with "manufacturer": storing it with a 'callable" (kind of) thing: the property with the comparator: != I have tried with "eval" and it may work, but the comparisons are going to be actually used to query a MySQL database (using sqlalchemy) and I'm a bit concerned about the security of that... Any idea will be deeply appreciated. Thank you! PS: The idea of all this is being able to generate a sqlalchemy query, so if the user inputs the string: Product.manufacturer != "foo" || Product.manufacturer != "bar" ... my tree thing can generate the following: sqlalchemy.or_(Product.manufacturer !="foo", Product.manufacturer !="bar") Since sqlalchemy.or_ is callable, I can also store it in one of the leaves... I only see a problem with the "!="

  • CSS: Horizontally scrolling image inside variable width div?

    - by neezer
    I have... <div id="tabs"> <!-- ... --> <div id="interior-photo"> <img src="..."> </div> <!-- ... --> </div> ... and ... #interior-photo { overflow-x: auto; } Basically, I have a page broken down into a main section and a fixed-width right sidebar. Within the main section, I have my tabbed div. The entire page grows with the width of the window, so when the window is resized, the tabbed div grows horizontally in size too. My problem is that the image that I'm loading inside one of the tabbed divs is generally much, much wider than the window usually is (they're panorama pictures; very lengthy horizontally, but not much vertically). I know that I can force the contents of #interior-photo to scroll horizontally using the CSS rule above, but that only seems to work when that same div has a fixed width. Since I want that div to have a variable width, it always seems to display the full width of the image, pushing my layout way out of whack. I know how to fix this using Javascript, but I was wondering if anyone has a CSS-only solution. If you need more information about my layout to solve this issue, please let me know. Thanks!

  • Array variable initialization error in Java

What should I do to set it right?
