• How to determine when the text of an html element is changed

  - by Micah

  I have an error message like this: <span class="errorMessage">Your input sucks!</span> and I need to determine when it changes. the validation framework I'm using sets the text when there's an error and removes it when it's complete. I'm hoping to tap into that by watching for changes to the text property of the element using jquery. Any idea of how to go about doing this? Thanks!

• Javamail: Get mail server information

  - by Nick

  I trying to find out how to get the mail server information on the server I connect to with Javamail. I know in the debug statements when you connect you will get something like "S: +OK [MAIL_SERVER_NAME] ready.". Is there an easier way to get this information (and hopefully more information) than just parsing the debug output?

• Can I Have Polymorphic Containers With Value Semantics in C++11?

  - by John Dibling

  This is a sequel to a related post which asked the eternal question: Can I have polymorphic containers with value semantics in C++? The question was asked slightly incorrectly. It should have been more like: Can I have STL containers of a base type stored by-value in which the elements exhibit polymorphic behavior? If you are asking the question in terms of C++, the answer is "no." At some point, you will slice objects stored by-value. Now I ask the question again, but strictly in terms of C++11. With the changes to the language and the standard libraries, is it now possible to store polymorphic objects by value in an STL container? I'm well aware of the possibility of storing a smart pointer to the base class in the container -- this is not what I'm looking for, as I'm trying to construct objects on the stack without using new. Consider if you will (from the linked post) as basic C++ example: #include <iostream> using namespace std; class Parent { public: Parent() : parent_mem(1) {} virtual void write() { cout << "Parent: " << parent_mem << endl; } int parent_mem; }; class Child : public Parent { public: Child() : child_mem(2) { parent_mem = 2; } void write() { cout << "Child: " << parent_mem << ", " << child_mem << endl; } int child_mem; }; int main(int, char**) { // I can have a polymorphic container with pointer semantics vector<Parent*> pointerVec; pointerVec.push_back(new Parent()); pointerVec.push_back(new Child()); pointerVec[0]->write(); pointerVec[1]->write(); // Output: // // Parent: 1 // Child: 2, 2 // But I can't do it with value semantics vector<Parent> valueVec; valueVec.push_back(Parent()); valueVec.push_back(Child()); // gets turned into a Parent object :( valueVec[0].write(); valueVec[1].write(); // Output: // // Parent: 1 // Parent: 2 }

• How to "grep" out specific line ranges of a file

  - by Mike

  There are often times I'll grep -l whatev file to find what I'm looking for. Say the output is 1234: whatev 1 5555: whatev 2 6643: whatev 3 If I want to then just extract the lines between 1234 and 5555, is there a tool to do that? For static files I have a script that does wc -l of the file and then does the math to split it out with tail & head but that doesn't work out so well with log files that are constantly being written to.

• String Array and ConvertTo-HTML

  - by Taylor Gibb

  I cant for the life of me get the contents of a string array (well its not strictly typed but all the items in the array are strings) to become a table, i am trying to use ConvertTo-HTML. For example: $arr = @("One", "Two") $arr | ConvertTo-HTML I have tried -As List, using fragments, even using InputObject, is it even possible ? Edit: i simply want to know if there is anyway to use an array as the input for the ConvertTo-HTML cmdlet, all it does is make a table with the length property of the strings.

• Port AS3/Flex app to iPhone

  - by John

  I believe Adobe tools like CS5 have ways to output as an iPhone app, but what about a regular AS3 or Flex project? Are there any tools to auto-port, or AS3/Flex iPhone implementations out there? Out of interest, how does the CS5 thing work? Is it a totally different code-path or something less drastic? For instance Flash supports Shapes and Timelines, etc... do they in fact provide an iPhone Flash runtime of some sort?

• Understanding PHP's way of reading if statements

  - by Masi

  How does PHP read if statements? I have the following if statements in this order if ( $number_of_figures_in_email < 6) { -- cut: gives false } if($number_of_emails > 0) { -- cut: gives false } if ( $number_of_emails == 0) { -- cut: gives true } The code behaves randomly. It sometimes goes to the third if clause and gives me a success, while sometimes to the one of the first two if clauses when the input variables are constant. This suggests me that I cannot code only with if statements.
