      • I need a regex that matches a string containing a delimited list of digits. While this seems fairly straightforward, the following requirements must be met: 1) Any number of spaces that occur before or after a delimiter should be accepted (e.g. '3 , 9 ' is OK) 2) The string can end with spaces or a delimiter (e.g. '3 , 9 , 8 ,' and '3 , 9 , 8 ' is OK) 3) The string can not contain any other

When I put the application on a client machine, it's fine provided the user has excel 2003 and either the PIAs are installed, or I distribute the dlls with my application. However, I've just tried this on a machi
