Hi, and thanks for looking. I have a 2D c# array, that has 50 as one of its dimensions. The other dimension depends on the number of rows in a database somewhere and is decided at runtime. How would I go about initializing an array like this? Currently my initialization for a single row looks like this, but I'm sure there's a better wa...

A tree is formed from a 2-d javascript array. The first dimension is the no of levels in the tree (vertical) and the second dimension is the the no of nodes in each level.Every node in the tree has got a check box.A node will be shown as checked if all its children are checked.All that code is written. Now, if some nodes in the tree are...

Now I have to write an interface, so that the C functions can be called from within Python. I use ctypes for that. C code: FOO* pytrain(float **data){ FOO *foo = foo_autoTrain((float (*)[])data); return foo; } ...
Hey guys I was wondering how I should do dynamic arrays in objc. Currently I have a function I wrote called malloc2D that looks like this: void* malloc2D(size_t unitSize, uint firstCount, uint secondCount){ void** pointer = malloc(sizeof(id) * firstCount); for (int i =0; i < firstCount; i ++){ pointer[i] = malloc(unitSize * second...
I need to keep checkboxes in a collection and access them via matrix coordinates. The following example works but only if I know the size of the matrix beforehand, since an array is used. What would be the best kind of approach/collection to achieve the same result but also allow the matrix to be defined at runtime, e.g. Dictionary<>, ...
I have a list of data that includes both command strings as well as the alphabet, upper and lowercase, totaling to 512+ (including sub-lists) strings. I want to parse the input data, but i cant think of any way to do it properly other than starting from the largest possible command size and cutting it down until i find a command that is ...
There a section in my code where I need to invert a matrix. That can only reasonably be done on a square matrix, in this case a 3x3 square matrix. The tool I'm using to invert the matrix kept saying that my array wasn't a proper square. So I did a little test: double[,] x = new double[3, 3]; MessageBox.Show(x.GetLength(0).ToString())...
I have a perl script that is only keeping the last set of records for a named set and I have more than one set of records. So its over writing the data in the hash and just keeping the last set.

So here's the input: $in['a--b--c--d'] = 'value'; And the desired output: $out['a']['b']['c']['d'] = 'value'; Any ideas? I've tried the following code without any luck... $in['a--b--c--d'] = 'value'; // $str = "a']['b']['c']['d"; $str = implode("']['", explode('--', key($in))); ${"out['$str']"} = 'value'; ...
Usually ‘expandable’ grids are represented as list of lists (list of rows, each row has list of cells) and those lists are some kind of linked lists. Manipulating (removing, inserting) rows in this data structure is easy and inexpensive, it’s just matter of re-linking previous nodes, but when it comes to columns, for instance removing...
I have an 8 by 8 matrix of sprites that I need to be able to rotate all of them 90 degrees at once. The way I've done it is using nested for loops, and a 2 dimensional array of sprite pointers. for(row = 0;row<9;row++){ for(column = 0;column<8;column++){ [trolls[row][column] runAction:[RotateBy actionWithDuration:0.01 an...
