| | Your code is very odd. Your first one use 'name' but your second one use 'id'. If you want to get it dynamically, you could use the same 'name' input tag. I am not sure whether you want it or not, so I just reuse your own code. Below is …  |
| | You may add a global variable to keep the ID of your setTimeout. Then, use that variable to clearTimeout() when onmouseover, but setTimeout() again when onmouseout. [code] //example var t t = setTimeout("slide()", 2500); //in function when onmouseover function mover() { clearTimeout(t) // not sure if you need window.clearTimeout() } … |
| | This isn't as easy as you think. The reason is that what the input you are expecting? Is there any prevention from illegal input? How about backspace? Do you enter by copy & paste or each key stroke? Anyway, the code below handles only invalid char but not backspace, and … |
| | Please use code tag (look at the [ code ] in front of your code and [ /code ] at the end (no white space inside, but I put them in just to by pass it). Anyway, for your first part, you do NOT need to do it as complicated …  |
| | ActiveX is only on IE browser. JavaScript, normally and supposedly, does not have authority to access local drive due to security issue. ActiveX allows JavaScript to access, but the client has to manually accept the action as well. What browser did you test it with? FF? Opera? Not IE? |
| | Your array is size 10. You are passing in the 'last' number as 10 while your sort seems to look for size 11 (0~10). Remember that array index is 0-index, not 1-index. You need to pass in a number less than size by 1 or do your loop up to … |
| | You just overload your new toString() method, not override. The toString() method does NOT take any argument. That's why you get the default value of toString(), the method you did not override. Also, any variable used inside toString() should comes from your own class variables. I see that you have …  |
| | Re: Euler problem 3 Your way of finding prime has potential to be slow. Your loop size could be at most the size of square root of the number you are finding. For example, you are checking whether 123 is a prime. Your loop size should go up to 11 and return true. If … |
| | If the main() method is there but no code inside, you should be able to run the class fine, but it will produce nothing. Usually, if I have main() method in a class object, I would implement quick tests for the class's functionality to see whether or not the class … |
 | How do you call Javascript in your HTML? Your validation will let empty string (contains only white spaces) pass because you are checking on var=='' but not var==' '. You should trim all strings you are checking before you do the validation, or you intend to let empty string to … |
| | [QUOTE]last question , can anybody show me the diffrernt in calling by value or refrence in my code?[/QUOTE] If I remember correctly (for C++), you need to add '&' in front of variable type in the function prototype in order to change from calling by value to calling by reference. … |
| | [QUOTE]But i have a question... now what i am currently trying to do is to transmit difference of radar_picture_array and radar_picture_array_old_transmitted which will be filled/mapped with values,strings once first radar_picture_array will be transmitted completely,also at reciever side radar_picture_array_recieved will be added to radar_picture_array_recieved_old to recover the original array that was … |
| | Depends on how you add it. If you add it as innerHTML and compose function calls with text, you could do that. If you add it with element creation, you could do it too but would be a little bit different way of adding function call to the page. It … |
| | The varible *= x means variable = variable * x. It is a short version. Also, 1 multiples with a number is equal to the number, so the loop could start from 2 without changing the result. For question #2, drawing a flowchart means you do it by hand, not … |
| | [QUOTE]We have been hired to write a program to determine the number of cases required to store boxes of cookies. A case of cookies can store 10 boxes of cookies. The user of the program will enter the number of cookies that have been purchased. The program should print out …  |
 | Doubly linked list should never point to a NULL. The sort method above needs a little modification. [CODE] struct node { node* next; node* prev; Person p; }; void sort(node* head) { node* n1; node* n2; for(n1 = head; n1->next != head; n1 = n1->next) { for( n2 = n1->next; …  |
| | [QUOTE]Please help me the code.[/QUOTE] Please do your own code, not come here to ask for code. The forum is to help you fix your code, not to do your own homework... By the way, the 'read only' means 'disable' or really means 'read only'. There are two different things. … |
| | You do not understand how the algorithm go or you do not understand how to apply Java to it??? If you do not understand the algorithm, you could look at [URL="http://en.wikipedia.org/wiki/Geometric_hashing"]wikipedia[/URL]. If you do not know how to apply Java to the algorithm, that may need a little more work … |

 | Sounds like you are implementing a text-based game... Anyway, a suggestion is that you should use HashMap instead of 2 arrays. The reason is that HashMap will map your attribute name with a value (in this case is an integer). Using 2 arrays could create a mess later on because … |
| | If a function is void, the only way you can display the result is to write to console immediately right after the calculation. In this case, while you are displaying each row, at the last column, which is the letter grade, call the function (may pass in total score depending … |
| | Re: twitter script Ajax maybe? Or just a simple javascript rewriting at certain area for certain length of time? Can't tell you exactly because you do not provide a link to a sample page you are talking about... |
| | If you do not want to have another array, sort the array first, and then do it as followed: [CODE] aArray <- a sorted array head <- 0 tail <- array.size() - 1 while head < tail swap aArray[head] with aArray[tail] increment head by 1 decrement tail by 1 [/CODE] … |
| | Not sure if you really want your methods to be static. I do not know how you call these methods. Maybe, taking 'static' keyword from method may be another way to make it work. By the way, I have no clue with anagramTable variable. Though, as stephen84s said, there may … |
| | Please create a new thread because this one has already been solved... |
| | I think line 42 should change from [CODE]myButton.onclick = addRadio;[/CODE] to [code]myButton.onclick = addRadio(questionNum);[/code] And then, you should change your function addRadio to take a question number argument. The reason is that your questionNum variable is a global. After you add a button, the variable value is increased. As a … |
| | Here is a simple way but not very efficient due to space required. [CODE] String[] words = lineString.split("\s+"); // use white space at least 1 between words int wordSize = words.size(); String firstWord="", lastWord=""; if (wordSize>0) { firstWord = words[0]; } if (wordSize>1) { lastWord = words[wordSize-1]; } [/CODE] |
 | Re: ajax and php You could use setTimeout() or setTimeinterval() in order to keep calling your Ajax script function (showHint()). You could change the bottom of your page from [CODE] <script type="text/javascript"> showHint("") </script> [/CODE] to somewhat like (not the best coding, but just to give you an idea) [CODE] <script type="text/javascript"> function keepCalling() … |
| | Please read or find code convention to follow because your code is very difficult to follow here. Also, please explain what your code is doing when you ask for help. Even better, give an example of input and expected output. [CODE] Base_Cost = 250 + 0; Area = Length * …  |
| | Just change code in actionPerformed() method from [code]jButton[i].setIcon(...)[/code] to [code]jButton[z-1].setIcon(...)[/code] The reason is that you are using 'i' as index and now 'i' value is the length of JButton objects. You picked the value from the button, but not use it in your call. Also, it has to be z-1 … |
| | Indeed, it is unclear... Also, you are asking for brain storm here... I am not sure if this would be the right forum for you even though it is going to be C++. What I mean is that this forum is for answering question about C++, but not about designing … |
| | From the look at the code, I believe you are working on computer vision project doing edge detection or such. Anyway, I would take a closer look at how you implement populateMatrix() which is called before your first error you found. The reason is that these functions could have changed … |
| | What do you want to match? You could just add a comma in it. Though, I'm not sure if the regexp you are using really covers all cases you want. [code] var regname=/^[A-Za-z,\.\-'\s]*$/ [/code] Not sure what you are trying to match for... You use * which means you also … |
| | Not sure... Have you tried [code] window.open('."+tempFileName+"','myWindow').print() [/code] instead of assign window.open to printWindow, and then call print()? |
| | I have updated some of your code, but it is not perfect. There are too many things that need improvement or reorganize your thought. I can see that you are new to the language. I am not sure that you are learning it the right way... You need more reading! …  |
| | Re: word wrap code If your code gets very long each line, you may need to reconsider how you code it or how your variable name should be. Yes, there may be a way to speed up or optimize your code by putting it in one line, you are trading off with its readability. …  |
| | Next time, please wrap your code around with the code tag. It would be easier to read. [CODE] #include <iostream> using std::cout; using std::cin; using std::endl; int count; int score; int getScore(); // function prototype void printGrade( int score ); // function prototype int main() { for ( count = … |
| | Re: Graphs You may need Graphics and Graphics2D classes. Then, you may want awt and/or some swing classes depending on your style of coding. Use google and search for sample code for graphic 2d. |
| | I agree with fxm. Anyway, there are many ways to do this. One way to do this is to write and delete message from your main HTML. Assuming that you have a div "loading" element inside your main HTML. At the top of your Ajax call function, you could put... … |
| | In my opinion, I don't think it is different for anyone who works on large project. The only different is how you prepare for a project. In pure computer science, there is no class that teach you how to create or develop a large project, but you learn about how …  |
 | Also, you are incrementing counter inside the loop! Take the line that increment counter out of for-loop. The for-loop automatically increase the variable counter used for the loop. You are not supposed to increment it yourself unless you want to do certain skipping. Yet, you should use while loop instead … |
| | Does the select() method supports multiple selection? Anyway, you are not searching through the whole string but stop at the first occurrence found. [CODE] int start = jTextArea1.getText().indexOf(search); if (search != null) { jTextArea1.select(start, start + search.length()); jTextArea1.requestFocus(); } [/CODE] Should try this... [CODE] int start = jTextArea1.getText().indexOf(search); while (start>-1) … |

| | Sorry, I am not going to register on the site... But one suggestion that you may need to look for is to escape string before you pass into any function. Normally, the string contains special characters, especially single or double quote, that JavaScript may not end correctly. To me more … |
| | Re: Nim Game Java You could add as while (stones is >= (the number of stones left in the pile divided by 2) and the number of stones left in the pile is > 0) This case, you should not need the break in the loop. |
 | What browser are you using? Have you tested on all IE, FF, Opera, etc? When you said 'has stopped working properly', does that mean it has been working before? Or it has never been working at all? |
 | Have you tried to create font directly from CreateFont() instead of using CreateFontIndirect()? Also, why this [code]hFont = CreateFontIndirect( &logfont );[/code] becomes [code]font.name = name;[/code] |

| | Your code here doesn't work the way you want because your count is 5 after it gets out of the loop. As a result, the Random[5] is out of bound. [CODE] if (source == cButton) Random = new int[5]; int count = 0; double average = 0; int Max = … |
The End.
