I suppose you need VBA code:

Dim r As Range
Set r = Range("A1").Columns(nCol)
GetColumnAddress = r.Address
End Function

Out of curiosity, are you using a DOCTYPE, and if so, which one? I'm not saying incompatabilities with the DOCTYPE are the issue, but quirks mode is something to rule out before trying anything else. |
Lose the parentheses and commas.
Calling your function as:
$s = CreateAppPoolScript "name" "user" "pass"
gives:

How do I find the Excel column name that corresponds to a given integer? |

I just wonder a bit whether or not GDI+ is still a technology worth using, especially in a .net sense.

One of the most frustrating things about writing unit tests is dealing with dependencies. One of the greatest things about Test-Driven Development is that it produces code that is decoupled from its dependencies. Cool, huh?

Is the type of id compatible with 555? Or has it been changed to a non-integer type?
Alternatively, does the 555 argument somehow go missing (e.g. if you are using JDBC and the prepared statement did not get its arguments set before executing the query)? |
If you're shelling out, I'd use the reg command (details below). If you can tell us what language you're working with, we could provide language specific code.

How much control do you have over the download process?

Assuming "alphanumeric" means letters and numbers, you could treat each letter/number as a base-36 digit. Unfortunately, large strings will cause the number to grow rapidly and you'd have to resort to big integers, which are hardly efficient.
