Think of multi-dimensional arrays in terms of a table holding columns and rows. To create a multi-dimensional array simply specify the number of columns and rows you want the array to have.
For example myArray(2,3) would have 3 columns and 4 rows.
The table below could represent our multidemsional array 'myArray(2,3)'.
Each cell holds a value. Below cell (0,3) holds a "bmw".
| 0 | 1 | 2 | |
| 0 | toyota | white | 22.000 |
| 1 | ford | blue | 12.500 |
| 2 | porshe | red | 50.000 |
| 3 | bmw | yellow | 26.000 |
Below is what a multidimensional array would look like that held the values in the table above;
<%
Dim myArray(2,3)
'myArray(col,row)
myArray(0,0) = "toyota"
myArray(1,0) = "white"
myArray(2,0) = "22.000"
myArray(0,1) = "ford"
myArray(1,1) = "blue"
myArray(2,1) = "12.500"
myArray(0,2) = "porshe"
myArray(1,2) = "red"
myArray(2,2) = "50.000"
myArray(0,3) = "bmw"
myArray(1,3) = "yellow"
myArray(2,3) = "26.000"
%>
Using our array 'myArray(2,3)' that we created above we could create a HTML table and display the array values with the code snippet below;
<%
Response.Write "<table border='0'>"
Response.Write "<tr><td>Row</td><td>Car</td>"
Response.Write "<td>Color</td><td>Cost</td></tr>"
'In our code below you'll notice UBound(myArray,2).
'The 2 is an optional parameter, it
identifies which
'dimension of the array you want to find the highest element of.
'In this case 2 signifies the rows dimension
'1 is the default and would apply to the columns
'the highest element in the row column in this case is 3
'so we could look on our loopcounter going from 0 to 3 i.e. For
i=0 to 3
'ArrayDimension defaults to 1, so if you are checking a 1 dimensional
array or
'you want to check the first dimension you can leave this out.
For i = 0 to UBound(myArray,2)
Response.Write "<tr><td>" & i &
"</td>"
Response.Write "<td>" & myArray(0,i) &
"</td>"
Response.Write "<td>" & myArray(1,i) &
"</td>"
Response.Write "<td>" & myArray(2,i) &
"</td></tr>"
Next
Response.Write "</table>"
%>
The above code displays the following result:
Row Car Color Cost
0 toyota white
22.000
1 ford blue 12.500
2 porshe red
50.000
3 bmw yellow
26.000
