Thanks Col.
Mark, the build info string is of the format:
VM.mm, Build X
where'M' is the major version and 'mm' is the minor. 'X' is an integer which is incremented every time it's built.
For example:
V1.14, Build 206
If you extract the string between 'V' and ',' and convert it to a floating point number , that's the version number that can be compared (obviously you can multiply it by 100 to get an integer if necessary).
Cheers,
Stu.
