I have tried everything to parse the comma values correctly, but the "id" column in mysql comes up short, as it reads "text", and not "text,text,text".

I can read back the values (from data members) just fine in the loading function. The problem occurs when I try to read back the values in my main rendering loop. There is an a...
How would you obtain the min and max of a two-dimensional array using LINQ? And to be clear, I mean the min/max of the all items in the array (not the min/max of a particular dimension). Or am I just going to have to loop through the old fashioned way? ...
I have a multidimensional array. The array itself is fine. My problem is that the script takes up monster amounts of memory, and since I'm running this on my MAMP install on my iBook G4, my computer freezes up.

I have a 3 dimensional array (5 x 5 x 3) and I need to post (5 x 5 x 1) to Sheet1, (5 x 5 x 2) to Sheet2, (5 x 5 x 3) to Sheet3. Because I am building this 3 dimensional array inside 3 nested for loops, I cannot use a for loop to access the (5 x 5) part of the loop. Is there any identifier that tells excel to index all elements of an a...

I am trying to populate a dynamic 3 dimensional array so I don't have to type it all out var o = { matrix: (function(n) { for (var x = 0; x < n; x ++) { for (var y = 0; y < n; y++) { for (var z = 0; z < n; z++) { this[x][y][z] = -1; } } } }).call(Array, 5), ... } The message I get is...
With a 1D array, I can use the sum method to get the sum of all the values. int[] array = {6,3,1}; Console.WriteLine(array.Sum()); With a multidimensional array (3D in my case), this can't be done. Obviously I could go all foreach on it, but this seems verbose and I suspect it will perform badly. Is there a way to flatten the array? ...
