• Slide Effect happening too many times

  - by Abs

  Hello all, I call this functions on onmouseover and onmouseout for several divs. //Takes effect on divs with id, 62,63,64,65... function slide_it(id){ $('#options_'+id).slideToggle('slow'); } The problem is that if I move my mouse over and then mouse out, then again, mouse over and then mouse out. If I do this several times, the slide effect happens the same number of times I moved my mouse over and out of the div, as expected. But I can't figure out how I can do this once? I can set a variable, but I have several divs that this function is used by and I can't think of a simple way of doing this rather than storing things into an array, but this is messy! I really appreciate any help on this that is simple to implement! Thanks all for any help

• How do I display/compare a dynamic value of a mysql row in a if statement?

  - by Ralph The Mouf

  I have a checkboxes on my site that when unchecked, update their row in in the db as unchecked, and if checked,update their row in the db as checked. I am creating an ifstatement that will commence with its command if checked, and not if unchecked. I have echoed the variable and it is holding the proper value (checked or unchecked) but not sure if I am syntactically correct on displaying the state of the row in the db. This is what I am trying and will not work. I am new at php still and thank you very much for any help. if($auth->check_prof == 'checked'){// do the stuff in here}

• jQuery cycle query

  - by Happy

  We have a script used for each .item: $(".item").each(function(){ item_link = "http://..."; block = $('.block', this); $.get(item_link, function(data) { var src = $('img.slide', data).attr('src'); block.html(src); }); }); item_link variable is uniquie for each query. There can be 100 .item or more. The problem is - server has limit on connections at the same time, that why some .item get var src, some not. The best solution is to use just one .get at the same time. I think there should be some counter, if .get is finished - it gives message "I'm finished, you can start" to the next .get and so on. How to do that? Thanks.

• Property and Encapsulation

  - by Lijo

  Hi Team, Following is a question regarding using Properties in class. I am software engineer with 3 years of experience. I have been using public properties instead of exposing member variables publically. Many a people told that this approach helps in encapsulation. I don’t realize any encapsulation advantage by making it a property. While discussions, I came to know that not many people knows about the real reason for going for Property. They just do it as part of coding standard. Can someone clearly explain how Property is better than public member variable? How it improves encapsulation? Thanks Lijo

• PHP $_REQUEST doesn't contain all $_GET varaibles

  - by pinky0x51

  Until today I thought that $_REQUEST always contains all variables form $_POST and $_GET. But today I had the strange experience that one variable is part of $_GET but not part of $_REQUEST. I played a little bit around with the URL which hands over the parameters and it seems like always the fist parameter is missing in the $_REQUEST array. Do you have any idea why this could happen? Thanks! URL: localhost/?app=files&getfile=ajax/newfile.php?dir=%2Ftest4&source=http%3A%2F%2Fl??ocalhost%2Fimg%2Flogo.svg&filename=logo.svg&requesttoken=e250827c341650990cd4

• Python finding index in a array

  - by NIH

  I am trying to see if a company from a list of companies is in a line in a file. If it is I utilize the index of that company to increment a variable in another array. The following is my python code. I keep getting the following error: AttributeError: 'set' object has no attribute 'index'. I cannot figure out what is going wrong and think the error is the line that is surrounded by **. companies={'white house black market', 'macy','nordstrom','filene','walmart'} positives=[0 for x in xrange(len(companies))] negatives=[0 for x in xrange(len(companies))] for line in f: for company in companies: if company in line.lower(): words=tokenize.word_tokenize(line) bag=bag_of_words(words) classif=classifier.classify(bag) if classif=='pos': **indice =companies.index(company)** positives[indice]+=1 elif classif=='neg': **indice =companies.index(company)** negatives[indice]+=1

• Byte manipulation in PHP

  - by Michael Angstadt

  In PHP, if you have a variable with binary data, how do you get specific bytes from the data? For example, if I have some data that is 30 bytes long, how do I get the first 8 bytes? Right now, I'm treating it like a string, using the substr() function: $data = //... $first8Bytes = substr($data, 0, 8); Is it safe to use substr with binary data? Or are there other functions that I should be using? Thanks.

• get function address from name [.debug_info ??]

  - by user361190

  Hi, I was trying to write a small debug utility and for this I need to get the function/global variable address given its name. This is built-in debug utility, which means that the debug utility will run from within the code to be debugged or in plain words I cannot parse the executable file. Now is there a well-known way to do that ? The plan I have is to make the .debug_* sections to to be loaded into to memory [which I plan to do by a cheap trick like this in ld script] .data { *(.data) __sym_start = .; (debug_); __sym_end = .; } Now I have to parse the section to get the information I need, but I am not sure this is doable or is there issues with this - this is all just theory. But it also seems like too much of work :-) is there a simple way. Or if someone can tell upfront why my scheme will not work, it ill also be helpful. Thanks in Advance, Alex.

• How to use composition from another class to set Name?

  - by user1874549

  I have some of the code here. I am trying to use one class to reference another so I may obtain the first name of the person. I want the firstName in main class to work but IDE mentions the variable isn't found. Will replacing 'first' with 'firstName' work? Main class: public BasePlusCommissionEmployee( String first, String last, String ssn, double sales, double rate, double salary) { cE = new CommissionEmployee( first, last, ssn, sales, rate ); setBaseSalary( salary ); } public void setFirstName(String firstName) { // Trying to get this to work... cE.setFirstName(first); } SubClass: private String firstName; public void setFirstName( String first ) { firstName = first; }

• How to achieve Bottom Align floated div that sizes to it's container.

  - by Davy8

  How can I achieve the following layout? Specifically the positioning of Image and DIV I've found that unless I set a specific width for the Div, it will just go on to the next line and take up the full width of the container. Additionally aligning it relative to the bottom of the image is giving me trouble. Currently they're both float:left Edit: The two solutions so far work if the image is a constant width which I guess I could work with, but it's going in a Wordpress theme for an author's profile page and it's possible that images would have slightly variable widths. Is there a solution that would have the Div right next to the image (minus padding) regardless of how wide or narrow the image is? Basically having the div adjust its width to accommodate the image width.

• Windows C++: LPCTSTR vs const TCHAR

  - by mrl33t

  In my application i'm declaring a string variable near the top of my code to define the name of my window class which I use in my calls to RegisterClassEx, CreateWindowEx etc.. Now, I know that an LPCTSTR is a typedef and will eventually follow down to a TCHAR (well a CHAR or WCHAR depending on whether UNICODE is defined), but I was wondering whether it would be better to use this: static LPCTSTR szWindowClass = TEXT("MyApp"); Or this: static const TCHAR szWindowClass[] = TEXT("MyApp"); I personally prefer the use of the LPCTSTR as coming from a JavaScript, PHP, C# background I never really considered declaring a string as an array of chars. But are there actually any advantages of using one over the other, or does it in fact not even make a difference as to which one I choose? Thank you, in advanced, for your answers.

• Simple parameter checking function, here just want the % to be allowed

  - by abas_rafiq

  I'm using PDO's bindParam. This is the function which checks every GET variable on the website. After changing it will echo it out: function Check_Get_Param($val){ $value1=addslashes($val); $string1=htmlspecialchars($value1); $string2=strip_tags($string1); $string3=intval($string2); return $string3; } Hhere this will output the result: Check_Get_Param($_GET['id']); Now the idea is any id or id= any or id = % $_GET['id'] = % will result 0 as % is not integer. How to allow % also? How do I modify this function or any other function that I could filter the GET parameters so I could keep out the web from injections?

• C++ inheritance doubt

  - by Poiuyt

  Can you explain why this is not allowed, #include <stdio.h> class B { private: int a; public: int a; }; int main() { return 0; } while this is? #include <stdio.h> class A { public: int a; }; class B : public A{ private: int a; }; int main() { return 0; } In both the cases, we have one public and one private variable named a in class B.

• writing terminal output to file

  - by user1551817

  On my machine, I have some software which takes commands in the terminal and returns a list of values. To run it, I have to type something like: pdv -t filename I am trying to run it as part of a python programme. When I run the following: os.system('pdv -t %s' % (epoch_name)) then I get the values that I desire returned to my terminal (where epoch_name is the variable name for the filename). But when I try to write the result to a file: os.system('pdv -t %s % "(epoch_name)" > 123.txt') the file 123.txt is produced but it is empty. I know that I am misplacing the " and/or ' characters, but I can't figure out where they should go. Any help would be gratefully received!

• Error while trying to reverse a char array in C++

  - by mpminnich

  Hi, I'm trying to get better at C++ (I know a little). I'm working on character arrays. I found an exercise where the objective is to reverse a character array (after I convert it from an integer). I'm getting the following error (using VS2005): Run-Time Check Failure #2 - Stack around the variable 'revBuffer' was corrupted. When I step through the code, I notice the following: revBuffer = 0x0012fe40 "100899ÌÌÌÌÌÌÌÌÌÌ998001" The relevant code is below. char buffer[5]; char revBuffer[5]; int i; int j=5; long number = 998001; itoa(number, buffer, 10); for(i=0; i<strlen(buffer);i++) { revBuffer[j] = buffer[i]; j--; } Any help would be great. TIA!

• Best way to put user input into generated javascript?

  - by Earlz

  Hello, I need for someone to be able to put some text into a page and then this gets sent to the server, saved in the database, and else where this text is put into a javascript variable. Basically like this: Write("var myVar=\""+MyData+"\";"); What is the best way of escaping this data? Is there anything out there already to deal with things like ' and " and new lines? Is base64 my only option? My serverside framework/language is ASP.Net/C#

• Run ajaxed javascript

  - by user1905698

  I know this has been covered a few times, but I'm completely a noob when it comes to javascript so I have no idea what I'm doing. I am running a javascript that sends variables to a php file and that info is ajaxed into the current page using innerhtml. Here is that part of the code... `function givingHistory(dyear,did) { var divname="giving" + dyear; $.ajax({ url: 'finance/givinghistory.php', type: 'POST', data: { year: dyear, id: did }, success: function(givedata) { document.getElementById(divname).innerHTML = givedata; } }); } ` In the givedata function response from the php file there is a call to another javascript function that is already loaded in my common .js file (so both javascript functions are loaded when the page loads). How do I get the onClick that is added via innerhtml to work? Inside the php file, I check to see if id = a php session variable. If it does it spits out the text that includes the onClick.

• Why is casting and comparing in PHP faster than is_*?

  - by tstenner

  While optimizing a function in PHP, I changed if(is_array($obj)) foreach($obj as $key=$value { [snip] } else if(is_object($obj)) foreach($obj as $key=$value { [snip] } to if($obj == (array) $obj) foreach($obj as $key=$value { [snip] } else if($obj == (obj) $obj) foreach($obj as $key=$value { [snip] } After learning about ===, I changed that to if($obj === (array) $obj) foreach($obj as $key=$value { [snip] } else if($obj === (obj) $obj) foreach($obj as $key=$value { [snip] } Changing each test from is_* to casting resulted in a major speedup (30%). I understand that === is faster than == as no coercion has to be done, but why is casting the variable so much faster than calling any of the is_*-functions?

• EXC_BAD_ACCESS when returning a CGRect in iPhone

  - by pabloruiz55

  I have a class which must return a CGRect from one of its methods: -(CGRect)myRect { CGRect rect = CGRectMake(self.mySprite.position.x,self.mySprite.position.y,self.mySprite.textureRect.size.width, self.mySprite.textureRect.size.height); return rect; } I get an exc_bad_access as soon as i try to access the mySprite ivar. Thing is if i call it, the instance variable mySprite is full of garbage. BUT if i change the function to return void, self.mySprite does contain the correct data. -(void)myRect { CGRect rect = CGRectMake(self.mySprite.position.x,self.mySprite.position.y,self.mySprite.textureRect.size.width, self.mySprite.textureRect.size.height); return rect; } that does not crash when accessing mySprite...
