Customer .dbf

[TimStone]

I'm trying to run a sample, and it wants to use CUSTOMER.DBF. However I keep getting the error when trying to USE it that there is an unknown field type. I believe the first field is ID and the type is +. I finally saw this with an ASCII text editor.

The file cannot be opened in any of my file editors, ie. ADS Data Architect or DBU.

I found a Customer.ch in the samples directory and even linked it into the program.

The program I'm trying to test is EREP01.prg which I've linked into my main application. ( This is a pretty easy way I use for testing samples ).

Any ideas on how to get around this. The sample code is unmodified ( except to rename the function other than Main() ).

Tim, try with this version of FiveDbu
https://bitbucket.org/fivetech/fivewin- ... IVEDBU.EXE

It opens as a Type +, but trying to use that file in a program built with FWH 20.04, Harbour, and MSVC, when executing, it does not see that field type. Of course, I'm using the RDDADS ...

So I tested it with DBFCDX and it opens the browse ... but the program I wanted to test is still failing ... will look further.

So that + field type is not going to work with ADS ...

I think the field type "+" is not supported with ADS

[nageswaragunupudi]

AutoIncrement field in DBFCDX/DBFNTX is represented as "+".
AutoInc fields of DBFCDX/DBFNTX are not compatible with autoincrement field of ADS.

Older DBUs and other older DBF maintenance programs may not support recently implemented fieldtypes : +. =. @, V.
Such software need to be updated by their authors.

on samples there is a file to build customers.dbf without + field

Hello,

This is the fix for incremental fields:
