Populating 2d arrays [resolved]

I know that I can populate a 1d array like this:

VB Code:

Dim Ax1()
Cat = Array("q", "w", "e", "r", "t", "y", "u", "i", "o")

Is there a similar way to populate an array of 2d or more? There must be a better way than this:

VB Code:

Dim Ax2(2, 2)
Ax2(0, 0) = "q": Ax2(0, 1) = "w": Ax2(0, 2) = "e"
Ax2(1, 0) = "r": Ax2(1, 1) = "t": Ax2(1, 2) = "y"
Ax2(2, 0) = "u": Ax2(2, 1) = "i": Ax2(2, 2) = "o"

Because each time you are assigning a value to the 2d array, there is no way to loop through and apply values. This is the sort of thing that is used outside of loops.

I don't understand what you said, but I'll take it as a 'no'.

It seems to me that something like this should work:

VB Code:

Ax2 = Array(("q", "w", "e"), ("r", "t, "y"), ("u", "i", "o"))

Since I have no other replies, I assume that there is not way to populate a 2d array by listing arguments. Is there another way to store the same data? An array of arrays maybe? I have not dealt with arrays within arrays and I'm not sure how to go about it, or their similarity with multidimensional arrays.

Input, ideas, or examples?

Not sure this is exactly what you are looking for, but you can loop through an multi-dementional array and add values.

VB Code:

Dim MyArray(10, 10) As String
 
For i = 0 To 10
 For j = 0 To 10
   MyArray(i, j) = "Num" & i + j
 Next
Next
MsgBox MyArray(7, 9)

That won't work because my array values aren't sequential. I can't just use an increment to assign them. The array values are constant. I use them for comparison to evaluate input.

Thanks anyway!

You could just use a 1D array, and have functions to access it as if it was a 2D array.

You are right. I could use an increment and the Mid() function to loop through each position in the data within each array item to make it act like a 2d array. But if I wanted to do that, I wouldn't bother using arrays at all. I could just use one long string, taking data from the necessary position as needed.

Right now, the 2d array is working out fine. I just don't like that there isn't an easy way to populate it.

I don't think he meant to put a string in each 1d array slot and Mid$ it. A 2d array is probably layed out sequentially in memory (memory is sequential, anyways). Therefore, if you have an array with dimensions of 3 and 4, you could arrange it in a 1d array like 111122223333. To find array(x,y) you would do something like

x * <size of dimension 2> + y. This would be a one day array.

Okay, I get the concept now. I decided to use a 8x3 array to store my data. The 2d array that I have discussed was just to make asking questions simpler. :D Since assigning 24 values in a multidimensional array isn't a major task, I will stick with what I have. If I had more values, this 1d aka fake 2d array might be useful. Also, I already have it coded... Thanks for the idea.

I guess I will mark this thread as resolved since my initial question has been answered.
