I'm trying to do an INSERT into a mysql db and it fails when any of the values are longer than 898 characters. Is there somewhere to get or, better, set this maximum value? I'll hack the string into chunks and store 'em in separate rows if I must, but I'd like to be able to insert up to 2k at a time. I'm guessing this is php issue as us...
I have often wondered this, is there a performance cost of splitting a string over multiple lines to increase readability when initially assigning a value to a string. I know that strings are immutable and therefore a new string needs to be created every time. Also, the performance cost is actually irrelevant thanks to today's really fas...

For example, the following should return 6 findMaxLen("a,set,of,random,words") Of course, it's fairly trivial to do this... <cffunction name="findMaxLen" returntype="Numeric"> <cfset var CurMax = 0 /> <cfset var CurItem = 0...

Just trying to understand how to address a single character in an array of strings. Also, this of course will allow me to understand pointers to pointers subscripting in general. If I have char **a and I want to reach the 3rd character of the 2nd string, does this work: **((a+1)+2)? Seems like it should... ...

In other languages this is an easy thing to do, but in C++ I am just lost. EDIT: For some context, this is for a WiX custom action. So portability is not a main priority, just the most simpl...
Hello, I'm extensively using hash map data structures in my program. I'm using a hash map implementation by Barry Kelly posted on the Codegear forums. That implementation internally uses RTL's CompareText function. Profiling made me realize that A LOT of time is spent in SysUtils CompareText function. I had a look at the Fastcode site...

Best I came up with was: public static string Trim(this string word, IEnumerable<char> selectedChars) { string result = word; foreach (char c in selectedChars) result = result.Replace(c.ToString(), ""); re...

If I add: TextTrimming="CharacterEllipsis" TextWrapping="NoWrap" on the TextBlock, an ellipsis will appear at the end of my string when the column gets smaller than the length of the string. What I need is to have the ellipsis at the beginning of the string. I....
