call toDbf() from xbrowser command line

[Marc Venken]

I want to call Xbrowser with extra functions...
I open the file, must change the colums (prefered with Xbrcolselector function to tag more than 1 field)
and than save the file with the selected fields.

Now it errors out...

I'm not using it with xbrowser command, but now from a normal xbrowse()

The browse started with many colums and I reduced them to just the 4 I want.
I reduced them with the function XbrColSelector( oBrowse ) below.


I'm using todbf() the wrong way, because I get not the result i want..
The browse has other column names and the todbf = using fieldnames i guess

There is a post from Mr. Rao that there are 3 options (dbf fields, oBrw: columns names) to put in a array, but for me only dbf seems to work.
Any sample from Xbrowse options ? I need the changed headernames to become the fieldnames of the new files.

MsgGet() returns .t. or .f. not the new value.
Please change this function

function exportdbf(oBrw)

Syntax of ToDbf()

Code: Select all  Expand view

ToDbf( cFile, ;  // dbf file name
          [ bProgress ], ; For meter
          [ aCols ], ; // Array of column objects
          [ lPrompt ] ; default .f. If .t., a dialog appears for edititing the structure of dbf
)

Even if there are many columns, we can save only selected columns by specifying { oBrw:oCol( "HEADER1" ), oBrw:oCol( "HEADER2" ), ... } as the 3rd parameter.

In the present implementation, column headers are used as field names. There is no provision now to map different field names for the columns. We may consider implementing in the future.

It is possible to specify .T. as the 4th parameter and then edit the structure manually.
Please try.
