U3- CD-ROM mode |
Tue, Mar 21 2006 10:17 PM | Permanent Link |
Herb (Kraft) | I am working on moving many of our programs over to U3.
U3 (at www.u3.com) is an OS add on that is bundled on various kinds of removable drives like USB thumb, stick, etc. I need read only access to tables (for example, classic books, bible..... which we have been selling for YEARS with DBISAM). Although I am just starting testing, let me verify that if the tables are marked read only in the IDE that DBISAM will put it lck files on an available harddrive. If so, is there a hierarchy? That is, does it try c:\, d:\ etc.? I also will need to nuke the lck file after the program is over (must, must, must, must, must, must, must do that- the U3 standard does not permit changing the host system.) Can someone help me with some code or tips on where the lck file might be and how I can assure that I have nuked it with extreme prejudice.... Thanks Herb |

Herb (Kraft) | If I were to leave the files on the U3 disk and load them into MEMORY does that avoid the
lck issue? |

If it can't create it there, it automatically treats the the entire database as read-only. << I also will need to nuke the lck file after the program is over (must, must, must, must, must, must, must do that- the U3 standard does not permit changing the host system.)
