Yes we did try take the max out, but then the problem comes in when a record is deleted. For example, if we have ten records but number five is deleted, then since there is now nine records, the next ID will be number 10. But number 10 still exists.
We then tried to simply generate a random number but there is something wrong with our block of code as only the 3 same numbers keeps getting generated.

If you use the Max(column) to insert all your records then the behavior that you speak of wouldn't happen. Meaning, if you delete a record, the key for each record has not been altered. So if you take the Max(column) for the new record the answer will be LL010 still and you add 1 to it. So you will be inserting the new record with the key of LL011.
Select Max(KeyID) From Table 'returns LL010 add 1 and insert new with LL011
You would only be inserting LL010 again if the user deleted LL010 otherwise adding one will always result in a non-duplicate key.

Heres an idea, assuming SQL Server
Add 3 fields to the table
IDNo int Identity(1,1)
Prefix char(2) default 'LL'
TableID varchar(20)
Add a calc in your insert proc to add prefix & IDNo together and stick into TableID. I think the IDNo may only be generated by the commit of the insert transaction.
You can probably do the last step with a trigger but I loathe triggers so would not recommend it.
OR
do a select top 1 on the id, increment and save with the prefix, caveat this will be nasty on a high use system.

Hi
I have a VBA application that reads from a config file on a network drive. It does this fine.
However when I use the File System Object to look for directories below the network path eg:
FSO.FolderExists(path) where path is \\DansComputer
It returns false.
Does this function work accross a network and if so what am I doing wrong. (It has worked fine locally).
Thanks
Dan

\\DansComputer is the machine name not a folder name

Thanks for your reply - how do i get it to look at a seperate machine then?
I had assumed it would just see something like \\DansMachine\Work as a folder.
Thanks

You have to supply the complete UNC name to the root of a file share at least:
\\servername\sharename\
or somehwere below that:
\\servername\sharename\folder\folder\...
|
|
|
|
|
You first need to share the folder that you wish to access on DansMachine for example give the folder a name like DansSharedFolder then your path variable value should be something like \\DansMachine\DansSharedFolder

Kind of like the "UniBomber". Shows up at random, voting posts a 1 that really don't deserve it.
