read data from a random access file created in vb6

I have some random access files created in vb6 and I need to read the data from them.
The problem is I dont know the record structure of these file.(As far as I know it is a must.)
Ive found some VB source in the web saying the data can be accessed but no further info how to.
Can anybody help me resolve this?

Thanks in advance.
