VisualBasic 6 is useful if you want ot access the MetaStock File Library and make form based applications etc

Please tell me how to use MFL from Visual basic

If any body know how and have a sample code to start getting data from a .DAT securtiy file and save it in Access Dbase

Thanks for all in advance

Hi wabbit,

Thanks for your quick response , I would like to have it in a dbase to do alot of analysis and queries and reports on this data ( both Historical and Interday).

Actualy i got the attached Code from earlier disccusion

and its retriving security information from a .DAT file but the problem is the information data is not correct . i donno may be the the problem is (BINARY data and ASCII data type format) (how can i declare the deferent between tow types).

so please if you have better sample code (Visual Basic or VBA for Access) to retrive the correct data from (Interaday) .DAT files for your information the .DAT files it's not produced by MetaStock it's produced by another trading software but the same type of metastock because metastock can read it.

Anothe Solution if you can help ':-( how I can link to .DAT interaday) by VBA for Access Dbase.
