I gave my application to someone, and he installed it.

He told me that he gets an "error 15".

I looked in MSDN to find help on error 15, and I found the "Trappable Errors" list, but guess what ? error 15 is not listed !!!

This is what is in the list of errors:
Code:
3 Return without GoSub 
5 Invalid procedure call 
6 Overflow 
7 Out of memory 
9 Subscript out of range 
10 This array is fixed or temporarily locked 
11 Division by zero 
13 Type mismatch 
14 Out of string space 
16 Expression too complex 
17 Can't perform requested operation
.....
.... etc....
Where is 15 ? why it's missing ? and why other error codes are missing too ??
