I was not able to view the attachment you attempted to post. For reading .ini keys, are you attempting to read a full dset of string data listed in the flie; such as, tag line 001 = "The begining..." tag line 002 ="...The End".
If you could please clarify your intention in reading the Key descriptor, and type of key you are attempting to read. I believe I could better answer you question.
