Accessing Visual FoxPro COM server from VB 6.0 -


the problem related usage of vfp com server visual basic 6.0 (sp 6).

code (relevant)

private movfpserver f_vfpsvr.vfpserver 

in sub:

dim orec f_vfpsvr.vfprecord  set orec = movfpserver.newrecord("loanmstr")     orec       .setfield "ssn", sssn       .setfield "awdyr", sawardyear       .setfield "tran_date", format(now, "mm/dd/yyyy")       .commit     end 

method "newrecord" movfpserver returns object represents new, empty record in vfp table "loanmstr".

code follows populate properties/fields , save data.

all works if vfp com server built using vfp 8.0 , does not work when built using vfp 9.0.

specifically, vb application errors out @ line of code:

set orec = movfpserver.newrecord("stdmstr") 

com server throws exception: automation error -2147417851.

this happening on same machine.

vfp built com objects can behave little oddly @ times, when comes trickling errors stack.

but seems strange manifests when built in vfp9. believe there breaking changes in database stuff between 8 , 9 possibly you've hit 1 of them?

do have error function in vfp code? if not, try setting error properties in , interrogating them in vb when error?

ie, have like

function error(nerror, cmethod, nline)     this.cerrdesc = "error number: " + transform(nerror) + crlf + "message: " + message() + crlf  + "method: " + cmethod + crlf  + "line #: " + transform(nline)      comreturnerror(cmethod, this.cerrdesc)  endfunc
