Xbrowse multi dbcombos

[brewster]

Hello,

For my example, I'll use states.dbf and customer.dbf.

I have the need to have multiple (x4) Dbcombos, all using states dbf. to fill the customer.dbf (state, state1...etc.) fields.

I would add extra state field(s) in the customer.dbf (state1, etc).

I have prepared a sample below to illustrate ( along with a function to produce the Cust_2.dbf with the extra state1 field).

The sample is a modified version of Xbr_edit.prg supplied by Mr. Nages earlier.

Any help appreciated.

1) You can use same alias for any number of DBCOMBO controls.
Eg:
USE STATES

@ r,c, DBCOMBO oRec:State1 ......... ALIAS "STATES" ITEMFIELD "CODE" LISTFIELD "NAME"
@ r,c, DBCOMBO oRec:State2 ......... ALIAS "STATES" ITEMFIELD "CODE" LISTFIELD "NAME"

2) You need not always use DBF for DBCOMBO. You can also use Arrays. Same arrays for any number of DBCOMBO controls.

USE STATES
aStates := STATES->( FW_DbfToArray() )
aStateCodes := ArrTranspose( aStates )[ 1 ]
aStateNames := ArrTranspose( aStates )[ 2 ]
CLOSE STATES

@ r,c, DBCOMBO oRec:State1 ......... ITEMS aStateCoddes LIST aStateNames
@ r,c, DBCOMBO oRec:State2 ......... ITEMS aStateCoddes LIST aStateNames

Mr. Nages,

Thank you for the reply.

I understand your use of 1) & 2) in your response,

but not in the context of my above attached compileable sample.

How would 1) or 2) apply to configuring the

Code: Select all  Expand view  RUN

excerpt from compilable sample supplied above
           WITH OBJECT oBrw
                 :SetChecks()
                 :nEditTypes    := EDIT_GET
                 :bEdit             := { |oRec| EditDlg( oRec ) }

      WITH OBJECT oBrw:oCol( "STATE" )
         :nEditType     := EDIT_LISTBOX
         :aEditListTxt  := aStates
      END
      WITH OBJECT oBrw:oCol( "STATE1" )
         :nEditType     := EDIT_LISTBOX
         :aEditListTxt  := aStates
      END              

for editing of the Xbrowse.

And using either 1) or 2) in the EditDlg function still gets me

Mr Nages,

If after compiling and running the sample, could you suggest,
how I may get multiple dbcombos functional in this setting.
