Dbf index file

I was thinking maybe it is something with the program that blocks it. I tried with the program completely shut, it's still the same. Do you know of any program that can debug and look for a connection to the cdx file, I will try to play with the permissions in the mean time. Also, when I opened Index Manager in the same program, it says that there are no index files connected to that database, even though there is one.

There is an option where you can browse for your own index file, so I tried the CDX file, It responded with an error. I think that this program is using a special kind of index, maybe it's own kind of index?

That would explain why it doesn't insert it to the index file, it would also explain why DBF Manager acted so strange. There are 4 databases in total that I am using with this script, the other three has properly working indexes but they don't get updated , I can see what fields that are indexed. Funny, the most important database is the one that I can't see.

Maybe I can force a reindex now that I know how the index is built, or maybe usa a "drop index" command and then rebuild it.

I am sure that this are the indexes because they all had the same pattern surounding them and most of all, this are the only thing that could be read from the file, everything else were jibberish. I don't know which tag, order or if they are unique. But the three files had all ASC and no one was unique, and the tags I will give them that order that I found them in.

Anyway, I read about it on the internet and I think a MVP said that it might be a security feature from the program that blocks the index from being opened from any other program. Either way, if one database doesn't index out of three then that is okay But the other three databases are not working either I can't get the entrys to register in the CDX file Could it be that the program that created and uses this files have its own special-made cdxs?

When it's indexing, it says "indexing pro..

One doesn't have the same name, and it seems as if this case is very special and unusual and that the ordinary rules doesn't apply to it. The content you requested has been removed. Ask a question.

Specifically, any index file that's open when you modify the table should get updated automatically.

The index files called structural CDXs open automatically with the table, so always get properly updated. These are index files with the same filestem as the table.

Thanks Cetin Basoz, your code run perfectly without error, but the performance is still the same. I also tried with test data on my computer and I get the "faster" results with an index.

Maybe your P: drive is remote and it is losing time to bring in the index file? Did you try adding your index to structural CDX?

How many rows do you have??? Even without any index 60s sounds to be slow. My DBF has over 5M records. It was created more than 15 years ago, so the. NDX index file is used in different places in the system. Converting it to structural CDX is possible, but my boss does not like that :. You are right, my P drive is remote. If I bring it to local, it will take 30s for the query, but I cant still use that performance for production. Anyway, I marked your answer for future references.
