I declared a function of dll and works perfectly into visual foxpro enviroment, but when I build a executable doesn't work.
Somebody know what's the trouble ???

Below the code program:

local sArqImagem, sAssCentral

sAssCentral = space (3000)

sArqImagem = "C:\ALTERACAO\assinatura_digital2\imagens\f3b9dd4f2.jpg"

*

Declare egb_win_get_central_certificate in c:\libegb.dl string @cert_data

egb_win_get_central_certificate(@sAssCentral)


= messagebox (sAssCentral, 64, 'Assinatura Central')

return
