Read/Write INI file.
VBcoders
'*EXAMPLE: Var = ReadINI(filename, key) -- & -- WriteINI filename, key, value
'*WHATSNEW: Can write complete ini, can write header tags, BUGS FIXED!
'*NOTE: To write header tags just leave the [value] out of WriteINI and the [Key] is the heading (wrote to file in order used)
'*Check out my website for VB Tools to help you (Optimizer, Code Library, ect.) <http://LostEmpire.s5.com>
