  I need a javascript to replace i into I. This should apply to cases such as i'm good. So am i. He though i love him. The standard ThisContent = ThisContent.replace("i", "I"); doesn't work because it replaces every i. I also thought of ThisContent = ThisContent.replace(" i ", " I "); but it doesn't work for the first and second case. Any idea?

• jquery radio button group problem

  - by user198937

  Hi, I have a radio group which is validated for required. It works fine except when in certain cases I need to disabled first radio button leaving user to select one from remaining. Even in this case radios are validated but error message is not displayed. I believe its due to error message's association with first radio. Disabling other radio except first works fine too. Is there way around?

  I have a test script like this: package Test; sub new { bless {} } sub DESTROY { print "in DESTROY\n" } package main; my $t = new Test; sleep 10; The destructor is called after sleep returns (and before the program terminates). But it's not called if the script is terminated with Ctrl-C. Is it possible to have the destructor called in this case also?

  - by Olga

  Is it true that interfaces slow down programs? I have heard that this is the case because during running time each during each usage of an object implementing this interface the decision has to be made which class implementing the interface this object belongs to. I am especially interested in an answer for C++, but also in general. And if this is true, some numbers would be helpful, too. Thank you very much!

• how to tell which object called a delegate method (objective c)

  - by user353877

  Let's say you have two objects (UITextviews) in your class. When the text view changes, you have a delegate method that catches the change.. but how can you tell programatically WHICH object was changed and called the delegate ?? I have to be missing something, because this should be trivial, but I couldnt find anything. Note: In this case, its not possible to just break up the class to only have one object (there by bypassing ambiguity).. I looked for things like assigned variable names for nsobjects, nothing there
