• Java: equivalent to C's strnicmp? (both startsWith and ignoreCase)

  - by Jason S

  String string1 = "abCdefGhijklMnopQrstuvwYz"; String string2 = "ABC"; I had been using string1.startsWith(string2), which would return false in the above example, but now I need to ignore case sensitivity, and there is not a String.startsWithIgnoreCase(). Besides doing string1.toLowerCase.startsWith(string2.toLowerCase()); is there an efficient way to see if string1 starts with string2 in a case-insensitive way?

• Is it worth setting pointers to NULL in a destructor?

  - by Rob

  Imagine I have a class that allocates memory (forget about smart pointers for now): class Foo { public: Foo() : bar(new Bar) { } ~Foo() { delete bar; } void doSomething() { bar->doSomething(); } private: Bar* bar; }; As well as deleting the objects in the destructor is it also worth setting them to NULL? I'm assuming that setting the pointer to NULL in the destructor of the example above is a waste of time.

• 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?

• Python 3.2: How to pass a dictionary into str.format()

  - by Robert Dailey

  I've been reading the Python 3.2 docs about string formatting but it hasn't really helped me with this particular problem. Here is what I'm trying to do: stats = { 'copied': 5, 'skipped': 14 } print( 'Copied: {copied}, Skipped: {skipped}'.format( stats ) ) The above code will not work because the format() call is not reading the dictionary values and using those in place of my format placeholders. How can I modify my code to work with my dictionary?

  Hi, private void Form1_KeyDown(object sender, KeyEventArgs e) { if (e.KeyCode == Keys.W) player1.moveUp(); if (e.KeyCode == Keys.NumPad8) player2.moveUp(); } In the above code the moveUp methods basically just increment a value. I want it so both keys can be pressed (or held down)at the same time and both events will trigger. Thanks, Nevik
