• CKeditor 3.0 - How to know which toolbar button is clicked

  - by understack

  Hi, I want to update few variables when any of the toolbar button (like bold, italic etc) is clicked. I'm unable to trap 'click' event on any of these buttons. Could somebody give me an example when clicking on 'bold' button would also pop up an alert box? How can I trap 'paste' event? I've googled a lot and searched ckeditor forum but couldn't find any solution. Any pointer would be really helpful. Thanks.

• Multiplying char and int together in C part 2

  - by teehoo

  If I do the following: int c0 = CHAR_MAX; //8 bit int c1 = CHAR_MAX; //8-bit int i = c0*c1; //store in 32-bit variable printf("%d\n", i); //prints 16129 We can see that there is no problem with to 8-bit numbers being multiplied together, and producing a 32-bit output. However, if I do int i0 = INT_MAX; //32-bit int i1 = INT_MAX; //32 bit variable long long int ll = i0*i1; //store in 64-bit variable printf("%lld\n", ll); //prints 1..overflow!! In this case, two 32-bit variables were multiplied together, overflowed, and then were assigned to the 64-bit variable. So why did this overflow happen when multiplying the ints, but not the chars? Is it dependent on the default word-size of my machine? (32-bits)

• Create a New .Net Profiler Api

  - by daniel

  Hi everybody! i m a new programmer in .Net Profiler and Visual C++, i read many forums and weblogs for .Net Profiling and i have this question. my Profiler application must be a unmanaged code or i can use some class in .Net in my application? and what type of project i must create ATL with MFC Or ..? another question is how can i register my profiler dll file that every application of my computer use this profiler? where the best situation for re-write IL of a method (Enter method of profiler or JITCompilationStarted)? how can i get input variables of old method and send to new method? how can i change IL of a property or whole of a class? i want chane all datetime format of my dlls, and i think that i must search name of those method in JITCompilationStarted and then rewrite that methods,Do u have any better solution? thanks alot.

• Using static mutex in a class

  - by Dmitry Yudakov

  I have a class that I can have many instances of. Inside it creates and initializes some members from a 3rd party library (that use some global variables) and is not thread-safe. I thought about using static boost::mutex, that would be locked in my class constructor and destructor. Thus creating and destroying instances among my threads would be safe for the 3rd party members. class MyClass { static boost::mutex mx; // 3rd party library members public: MyClass(); ~MyClass(); }; MyClass::MyClass() { boost::mutex::scoped_lock scoped_lock(mx); // create and init 3rd party library stuff } MyClass::~MyClass() { boost::mutex::scoped_lock scoped_lock(mx); // destroy 3rd party library stuff } I cannot link because I receive error: undefined reference to `MyClass::mx` Do I need some special initialization of such static member? Is the whole conception of static mutex wrong?

• What are the main advantages of adding your custom functions to a javascript libraries namepsace?

  - by yaya3

  It is fairly well known in JavaScript that declaring variables within the global scope is a bad thing. So code I tend to work on contains namespaced JavaScript. There seems to be two different approaches taken to this - Adding your application specific functions to the libraries' namespace e.g. $.myCarouselfunction Creating your own namespace e.g. MyApplication.myCarouselFunction I wanted to know whether or not there is a 'better' solution or if they tend to meet somewhere close in terms of pros and cons. The reason for me personally deciding not to go with the library is for Seperation / Isolation / Lack of conflict with library code and potential plugins that are likely to share that namespace. But I am sure there is more to this. Thanks

• Screening (multi)collinearity in a regression model

  - by aL3xa

  I hope that this one is not going to be "ask-and-answer" question... here goes: (multi)collinearity refers to extremely high correlations between predictors in the regression model. How to cure them... well, sometimes you don't need to "cure" collinearity, since it doesn't affect regression model itself, but interpretation of an effect of individual predictors. One way to spot collinearity is to put each predictor as a dependent variable, and other predictors as independent variables, determine R2, and if it's larger than .9 (or .95), we can consider predictor redundant. This is one "method"... what about other approaches? Some of them are time consuming, like excluding predictors from model and watching for b-coefficient changes - they should be noticeably different. Of course, we must always bare in mind specific context/goal of analysis... Sometimes, only remedy is to repeat a research, but right now, I'm interested in various ways of screening redundant predictors when (multi)collinearity occurs in a regression model.

• PHP Sessions - Locking and Sharing questions

  - by Nuno Peralta

  Hi, I would like to know if it is possible to read $_SESSION attributes without locking it. Currently, session_start() locks SESSION, that means other PHP processes will wait until it is unlocked. But, some processes just want to get some $_SESSION variables, not to write on them. Is that possible to implement some function like session_get(string $id) which doesn't lock SESSION? Also, it is possible to share SESSIONs between browsers, once the user is logged in the same account, for example, using session_id('shared_vars_of_'.$userid). But, is that secure? Is this discouraged? Thanks, Nuno

• How can one put together multiple arrays into one string?

  - by Noor

  I'm having a hard time describing what I'm looking for. If we pretend that we're pulling an array (I've used the .split to get user input data) where each line represents a link. How can I then add an anchor tagg to that link that I'm pulling? I need to be able to put < a href=" + thearray + "anything< /a. The reason for this is that I'm dynamically creating a list. I think that if I create two variables, one with this part < a href=" one with the closing and then call some sort of function that puts those two and the pulled array in between them until the list is complete. Does this make any sense?

• JS function returning another function

  - by Michael

  I want to understand about variables, that has been used in returning function. This is example code Prototype = {} Prototype.F = { bind: function() { var args = arguments, __method = args.shift(), object = args.shift(); return function() { return __method.apply(object, args.concat(arguments)); } } } function ObjectA() { ... this.addListener = Prototype.F.bind(this.eventSource.addListener, this.eventSource); ... } var a = ObjectA(); a.addListener(this); // assuming 'this' here will point to some window object As I understand the returning function in F() is not evaluated until it's called in the last line. It's ok to accept. So addListener will hold a function body containing 'apply'. But what I don't understand, when addListener is called, what kind of parameters it is going to have? particularly _method and args will always be uninitialized?

• How to redefine symbol names in objects with RVCT?

  - by Batuu

  I currently develop a small OS for an embedded platform based on a ARM Cortex-M3 microcontroller. The OS provides an API for customer application development. The OS kernel and the API is compiled into a static lib by the ARMCC compiler and customer can link his application against it. The lib and the containing object files offer the complete list of symbols used in kernel. To "protect" the kernel and its inner states from extern hooking into obvious variables and functions, I would like to do some easy obfuscation by renaming the symbols randomly. The GNU binutils seems to do this by calling objcopy with the --redefine-sym flag. The GNU binutils cannot read the ARMCC / RVCT objects. Is there any solution to do this kind of obfuscation with RVCT?

• How to convert JavaScript dictionary into Python syntax

  - by Sputnix

  Writing out javascript dictionary from inside of JavaScript- enabled application (such as Adobe) into external .jsx file (or any other .txt file) the context of resulted file dictionary looks like: ({one:"1", two:"2"}) (Please note that each dictionary keys are written as they are the variables name (which is not true). A next step is to read this .jsx file with Python. I need to find a way to convert ({one:"1", two:"2"}) into Python dictionary syntax such as: {'one':"1", 'two':"2"} It has been already suggested that instead of using JavaScript's built-in dict.toSource() it would make more sense to use JSON which would write a dictionary content in similar to Python syntax. But unfortunately using JSON is not an option for me. I need to find a way to convert ({one:"1", two:"2"}) into {'one':"1", 'two':"2"} using Python alone. Any suggestions on how to achieve it? Once again, the problem mostly in dictionary keys syntax which inside of Python look like variable names instead of strings-like dictionary keys names: one vs "one"

• Custom Data Types

  - by Tinkerer_CardTracker

  Hello, quick question: I'd like to create some custom data types, but I don't think I'm asking the right question(s). There are "compound Boolean" values used throughout .NET, and I want to design some of my own. I've been using a series of Boolean variables, which works, but just isn't the same. Examples from .NET include: Color.Black Alignment.Centered [fontProperties].Bold* *I forget the actual name, but you get the idea I want to make something like this: ColorSortQualities None DistinguishColor DistinguishNumberOfColors DistinguishColorPattern Once that's been declared, I could do this: if(searchOptions.ColorSortQualities == DistinguishColor) [do stuff] What is this called? Thanks!

• String concatenation produces incorrect output in Python?

  - by Brian

  I have this code: filenames=["file1","FILE2","file3","fiLe4"] def alignfilenames(): #build a string that can be used to add labels to the R variables. #format goal: suffixes=c(".fileA",".fileB") filestring='suffixes=c(".' for filename in filenames: filestring=filestring+str(filename)+'",".' print filestring[:-3] #now delete the extra characters filestring=filestring[-1:-4] filestring=filestring+')' print "New String" print str(filestring) alignfilenames() I'm trying to get the string variable to look like this format: suffixes=c(".fileA",".fileB".....) but adding on the final parenthesis is not working. When I run this code as is, I get: suffixes=c(".file1",".FILE2",".file3",".fiLe4" New String ) Any idea what's going on or how to fix it?

• Assigning a MVC Controller property from Asp.Net page

  - by JasonMHirst

  I don't know if I've understanding MVC correctly if my question makes no sense, but I'm trying to understand the following: I have some code on a controller that returns JSON data. The JSON data is populated based on a choice from a dropdown box on an Asp.Net page. I thought (incorrectly) that Session variables would be shared between the Asp.Net project and the MVC Project. What I'd like to do therefore (if this is possible), is to call a Sub on the MVC that sets a variable before the JSON query is run. I have the following: Sub SetCountryID(ByVal CountryID As Integer) Me.pCountrySelectedID = CountryID End Sub Which I can call by the following: Response.Write("http://localhost:7970/Home/SetCountryID/?CountryID=44") But this then results in a blank page - again obviouslly totally incorrect! Am I going about MVC the wrong way or do I still have a hell of a lot more learning to do? Is this even possible to do?

• Corrupted image if variable is not static

  - by Jaka Jancar

  I'm doing the following: static GLfloat vertices[3][3] = { {0.0, 1.0, 0.0}, {1.0, 0.0, 0.0}, {-1.0, 0.0, 0.0} }; glColor4ub(255, 0, 0, 255); glEnableClientState(GL_VERTEX_ARRAY); glVertexPointer(3, GL_FLOAT, 0, vertices); glDrawArrays(GL_TRIANGLES, 0, 9); glDisableClientState(GL_VERTEX_ARRAY); This works ok: However, if I remove static from vertices and therefore re-create the data on the stack on each rendering, I get the following: This happens both on the simulator and on the device. Should I be keeping the variables around after I call glDrawArrays?

• Determine if a day of week and time fall in a custom weekend period

  - by Y Low

  I've been trying to come up with a method, that given a day of week and time of day, it will return if it falls under a custom weekend period. The weekend period is saved in 4 variables as follows: The day of week when it starts (0-6) The time of day when it starts (0-23) The day of week when it ends (0-6) The time of day when it ends (0-23) Based on these fields, the weekend period can be anything the user selected (even if it is well beyond a regular weekend) I've been banging this one for awhile but to no avail. I'm trying this in delphi but any language will do, as I'm looking for the algorithm and not the implementation.

• Check if checkbox is checked or not (ASPX)

  - by cthulhu

  I have the following code: (some.aspx.cs) if(Page.IsPostBack) { bool apple2 = false; bool pizza2 = false; bool orange2 = false; if (apple.Checked) apple2 = true; if (pizza.Checked) pizza2 = true; if (orange.Checked) orange2 = true; } (some.aspx) <tr> <td>Food:</td> <td>Apple <input type="checkbox" name="food" id="apple" value="apple" runat="server" />Pizza <input type="checkbox" name="food" id="pizza" value="pizza" runat="server" />Orange <input type="checkbox" name="food" id="orange" value="orange" runat="server" /></td> Now, i send the Boolean variables to SQL database. The problem is only with unchecked boxes. I mean, when you check some checkboxes it sends it as true (and that's right) but when i uncheck them it remains the same (true).

• reading unformatted fortran file in matlab - which precision?

  - by Griff

  I have just written out a file: real*8 :: vol_cel real*8, dimension(256,256,256) :: dense [... some operations] open(unit=8,file=fname,form="unformatted") write(8)dense(:,:,:)/vol_cell close(8) dense and vol_cell are real*8 variables. My code to read this in in Matlab: fid = fopen(fname,'r'); mesh_raw = fread(fid,256*256*256,'double'); fclose(fid); The min and max values clearly show that it is not reading it in correctly (Min is 0 and max is a largish positive real*8). min = 3.3622e+38 max = -3.3661e+38 What precision do I need to set in Matlab to make it read in the unformatted Fortran file? A somewhat related question: This Matlab code I am using reads binary files OK but not unformatted files. Though I am generating this new data on my Mac OSX using gfortran. It doesn't recognize form="binary" so I can't do it that way. Do I need to add some library?

• For REST, how do I receive posted data using PHP?

  - by netrox

  I want to set up a tiny RESTful interface for my web services using PHP. The problem is that I looked at frameworks and I cannot figure out how do I recieve the posted data without field names? For example, if a server posts data to my server, I cannot figure out how do I get it without needing the postfield (POST variables). Traditionally, with forms, people send post data with field names such as this: curl_setopt($ch, CURLOPT_POSTFIELDS, postfield=postvalue); and I would use PHP code like this: $postvalue=$_POST[postfield]; to get value of postfield but since the server posting data is not using postfield and is just sending XML, how do I get it without fields? How do I capture the XML? That's where I am lost.

• "Anagram solver" based on statistics rather than a dictionary/table?

  - by James M.

  My problem is conceptually similar to solving anagrams, except I can't just use a dictionary lookup. I am trying to find plausible words rather than real words. I have created an N-gram model (for now, N=2) based on the letters in a bunch of text. Now, given a random sequence of letters, I would like to permute them into the most likely sequence according to the transition probabilities. I thought I would need the Viterbi algorithm when I started this, but as I look deeper, the Viterbi algorithm optimizes a sequence of hidden random variables based on the observed output. I am trying to optimize the output sequence. Is there a well-known algorithm for this that I can read about? Or am I on the right track with Viterbi and I'm just not seeing how to apply it?

• Yet another Rails routing question

  - by danhere

  I can't seem to grasp the Rails routing just yet. I want to be able to link the site to, for example, ...com/store/xbox360/Mass Effect 2 (which is /store(my controller)/:system/:title). I have the database entries that include the :system and :title variables (?). How would I route these to show up and filter these entries? Or is this something I need to set up in the controller? I'm lost. Thanks so much for your help.

• Xcode Tips for Eclipse users?

  - by willcodejavaforfood

  Hi, I've been slowly working my way through the examples in Beginning iPhone Development and there are a few things that I have not been able to figure out, but I'm sure you guys can help me with it. In Eclipse there is a Source-Generate Getters/Setters, can you do something similar to synthesize properties in Xcode I also cannot seem to find a Refactor menu I'm also struggling to find the equivalent to Source-Override/Implement Methods --Edit-- I failed to describe my problem it seems. I do know that synthesizing properties will generate getters/setters for me, but I am looking for a way to generate the @property/@synthesize code, by selecting the variables. Short list to start with, but I will probably have more as my confusion grows in might. :)

• Where to maintain common information, that could be accessed by all forms

  - by The King

  Hi All, This is my first winform app in .NET... I have made a couple of ASP.NET app... In this app, I have some common variables, like current user name, his selected process etc.. etc.. This should be made accessible from all forms in the app at any time... How could I do this... Is there any place like "Session" in ASP.NET here... Further How do coders generally pass information from one form to another... Here I want to pass on the info I acquired in the first form to the subsequent forms... I use constructor overloading and pass the values as parameters... I'm pretty sure there has to be a better way to do it... Thanks for your time...

• Linux: Ways to communicate with kernel module from user space.

  - by Inso Reiges

  Hello, What are the ways to communicate with a kernel module from user space? By communication i mean sending information and commands between the module and a user space process. I currently know of two way: open/close/read/write/ioctl on published device node. read/write on exported and hooked /proc file. More specifically, can someone advice the best way to communicate with a kernel module that does not actually drives any hardware and therefore should not be littering /dev with stub nodes that exists solely for ioctl calls? I mostly need to check its various status variables and send it a block of data with a request type tag and see if the request succeeded. Inso.
