long file names

[Peterg]

Hello
I am trying to use lcreat to create long file names but each time i try i get a truncated name 8 characters long.

I can use the clfn.dll and this seems to work but occassionally it writes truncated file names aswell

Anybody any ideas

Peter,

Please review samples\LongName.prg

I have used this but I just get truncated file names

Peter,

It looks as a 16 bits limitation. With Harbour and FWH it works ok.

Yes it does work with fwh and gradually moving over to this

thanks
Peter

You could create it with a temp file name using 8.3 convention, and use the movefile api call to move it to a long file name.

Movefile ( "c:\temp\temp.fil" +chr(0) , "c:\folder\long file name.fil" +chr(0))
DLL32 FUNCTION MOVEFILE( cOldName AS LPSTR, cNewName AS LPSTR ) AS BOOL;
PASCAL FROM "MoveFileA" LIB "kernel32.dll"

I have found a tfln on Patrick Mast old pages which works very well. Only needs an extra obj linked in and very simple
