I've been fooling around with a very minimalistic jquery admin area menu. The thing is I want jQuery to build 3 equal menus with different ID's.

Hey there, I am using a List construct to handle the sequence in which images are drawn in "OnPaint". Now if my images are re-ordered (e.g. "brought to front" or "..to back"), I'd need to reposition them in my List. I have trouble doing so, because List doesn't support a method similar to setIndex(). So what I am trying to do is basica...

Simply put. Why did this make my code malfunction after awhile. //Color[][] colorArr = new Color[Width][Height](); private void shiftRowsDown(int row) { for (int i = row; i > 0; i--) { colorArr[i] = colorArr[i - 1];//<--This in particular } for (int col = 0; col < colorArr[0].length; col++) { colorA...
I'm wondering if LINQ methods like .Last and .Skip are optimized for arrays, List and the such. E.g. for an array I could do _array[_array.Length] to get the last element. Does _array.Last() actually enumerate through all elements and then return the last or is there actually some optimization built in? Might have to forgo fluency for p...

I've had a look on google and all I can find is a bunch of ugly while loops that dump the rows in an array list, is there a nicer way of doing...
