• Javascript jQuery ajax submit default data

  - by onlineracoon

  How to submit default data when using $.ajax? I have tried: $.ajaxPrefilter(function(options, originalOptions, jqXHR) { // can't access anything here... (tried jqXHR.data but undefined) }); $.ajaxSetup({ beforeSend: function(jqXHR, settings) { // can't access anything here... (tried jqXHR.data but undefined) } }); I need this so I can send my CSRF token, each time and when logged in submit the user ID each time. I prefer not to submit a token in headers. Thanks

• matlab: subs on symbolic constant returns scalar instead of vector for a vector input

  - by noam

  usually, symbolic functions return vectors for vector inputs: syms('x'); f=x*2; subs(f,[1 2 3]) outputs: [2 4 6] but doing f=sym('0'); subs(f,[1 2 3]); outputs: 0 and not: [0 0 0] so basically, my questions is how do I make f behave as a "normal" symbolic function. I can do something ugly like f=x-x to create a function that always returns zero, but is there a prettier way?

• call_user_function_array() and __construct

  - by John

  I'm working on a simple framework, and I'm having a slight problem. I'd like to use call_user_function_array() to pass parameters to a function. That's fine, except the function I want to pass it to is __construct. I can't create an instance of an object with cufa(), and by instantiating an object, and then using cufa to call that instance's __construct(), I run into problems with a broken class because I'm calling the constructor twice (and one time it's called wrong.)

• Is it possible to get a pointer to String^'s internal array in C++/CLI?

  - by CannibalSmith

  The goal is to avoid copying the string data when I need a const wchar_t*. The answer seems to be yes, but the function PtrToStringChars doesn't have its own MSDN entry (it's only mentioned in the KB and blogs as a trick). That made me suspicious and I want to check with you guys. Is it safe to use that function?

• Thread safety with heap-allocated memory

  - by incrediman

  I was reading this: http://en.wikipedia.org/wiki/Thread_safety Is the following function thread-safe? void foo(int y){ int * x = new int[50]; /*...do some stuff with the allocated memory...*/ delete x; } In the article it says that to be thread-safe you can only use variables from the stack. Really? Why? Wouldn't subsequent calls of the above function allocate memory elsewhere?

• Optimizing division/exponential calculation

  - by Saltheart

  I've inherited a Visual Studio/VB.Net numerical simulation project that has a likely inefficient calculation. Profiling indicates that the function is called a lot (1 million times plus) and spends about 50% of the overall calculation within this function. Here is the problematic portion Result = (A * (E ^ C)) / (D ^ C * B) (where A-C are local double variables and D & E global double variables) Result is then compared to a threshold which might have additional improvements as well, but I'll leave them another day any thoughts or help would be appreciated Steve

• mySQL convert varchar to date

  - by Jeff V

  I need to convert a varchar value of 1/9/2011 to a date in mySQL and I want only the month and year. So that I can then use the PERIOD_DIFF function (so I would need the above to be converted to 201101). I've tried various ways using the STR_TO_DATE function: SELECT STR_TO_DATE(CYOApp_oilChangedDate, '%m/%Y') FROM CYO_AppInfo But I get weird results... (for example: 2009-01-00) What am I doing incorrectly?

• javascript Refresh Div.

  - by Tom

  Hi, I am using this code to refresh the data inside of the div: <script> $(function() { $("#refresh").click(function() { $("#new").load("/new.php") }) }) </script> Except it loads the who page inside of the div, instead of just the information that is inside of the div. How do I make it refresh only the data that is inside of the div? Is there a way of doing it other than putting the information for that div in a seperate page?

• Returning the size of available virtual memory at run-time in C++

  - by Greenhouse Gases

  In C++ is there a predefined library function that will return the size of RAM currently available on a computer a program is being run on, at run-time? For instance, if an object is 4bytes, then can we divide the available virtual memory by 4 bytes to give an estimate of how many more objects could be stored by the program safely? I have used the sizeof() function to return the size of objects within my program. Thanks

• What is the purpose of using a reference to a reference in C++?

  - by SilverSun

  In my adventures studying the boost libraries, I've come across function signatures that have parameters which are a reference to a reference to an object. Example: void function(int && i); What is the purpose/benefit of doing it this way rather than simply taking a reference to an object? I assume there is one if it's in boost.

• How to call a method on UIButton in NSArray?

  - by user1792818

  I'm trying to enable a button but the button that I would enable in this function changes. I have an array of the buttons but when I use the .enabled on the array index I want it says that this doesn't work for IDs. I have used this array to set the text of each button before using: [[ButtonArray objectAtIndex: Index] setTitle:(@"blahblahblah") forState: UIControlStateNormal]; is there any way to use a similar function call to enable and disable?

• How to compare strings ignoring case (C++)?

  - by zebraman

  I am aware there is a function strcasecmp() that compares cstrings ignoring case, but I was wondering if there is a function that does the same thing except with strings? I am working with a bunch of strings, and feel like it would be terribly inefficient to have to use c_str() each time I want to compare them with strcasecmp(). Should I just use cstrings instead of strings...?
