    <p>I'm trying to create a permutation of a multidimensional array in classic asp (vbscript) and I'm seriously stuck. I've tried several functions of my own and also tried copying several php versions over, but I often end up with something that either goes into a buffer overflow / infinite recursion or I get results that are more like a combination than a permutation, if I understand the differences correctly.</p> <p>Lets say it's for a shirt. The shirt can have colors, sizes, and styles. (The actual system allows for any number of "groups" of options (think color, size, etc) and also any number of options within each group (each particular size, each particular color,etc).</p> <p>For example:</p> <pre> small med lg xl red blue green white pocket no-pocket </pre> <p>Note that the number of elements in either dimension of the array are unknown beforehand; also, not all second dimensions will have the same number of elements.</p> <p>I need to iterate through each possible unique option that contains an option from each row. In this particular example, there would be 32 options (because I need to ignore results that have an empty value for any given option, since asp doesn't really handle a jagged array the way I would expect. So: small red pocket small red no-pocket small blue pocket small blue no-pocket etc.</p> <p>Once I have this part done, I'll need to integrate it with some IDs from the database, but I'm fairly sure I can do that part on my own. It's the recursive function that's killing me.</p> <p>Anyone able to point me in a good starting place or help me out? Any help is MUCH appreciated!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
