Yet another DBU

[JosK]

With dba.exe i can not open this file:

proc main()
local i
rddsetdefault( "DBFCDX" )
dbcreate( "test", { {"USERID", "+", 4, 0 }, { "NAME", "C", 20, 0 } } )
//(autoincrement see + by userid)
use test
for i :=1 to 10
dbappend()
next

with hbide -> view -> idedbu it shows the test.dbf
(userid is 1, 2 to 10)

is there a dbu.exe of dba.exe that also kan open the autoincrement .dbf ?

Sadly, DBA doesn't support yet extended field types of Harbour

May be at the future

Hi friends,
I have downloaded hmgdbu as well as dba, in both apps I have a menu item to modify structure. and I can do a "modi stru". But I haven't found a way to erase a field in either app.

Can someone help please? Or do I have to go back to dosbox, where dbase is installed, and do it by dbase prompt?

Anyway thanks for both apps.

TIA
Robert

Hi Robert

Modifying structure of .DB file is a highly complicated process; even for most sophisticated db manager software.

Complication depends details of modification; does field count, names , type etc changed or not ?

For simple modification process is also simple:

- Define a new structure for target dbf
- Build an empty dbf with that structure
- Append old dbf to new one via APPEND FROM command

Without changed field specifications (decreased or increased field counts) this method runs well.

Without M (memo) field type we have another method:

USE <oldDBfile>
- COPY TO <newDBfile> SDF

Do necessary editing on this SDF by using any text editor

Build and USE a new empty dbfile depending that SDF

APPEND FROM <oldDBfile>

That is all

Hi esgici,

thank you,
that's a good solution.

Hi Robert,

Perhaps I am misunderstanding what you're intending to do, but I would try the following assuming:
fld_to_delete is the number of the field you want to delete
file_to_mod is the name of the dbf you are trying to modify/delete a field

copy structure extended to temp
use temp
goto fld_to_delete
delete next 1
pack
rename (file_to_mod) to temp2
create (file_to_mod) from temp
append from temp2
erase temp2.dbf
erase temp.dbf

Regards,

Jeff
