hbnetio

[Ana Mitoooo]

Exemplo:

Código: Selecionar todos

   cFolder := '\Temp'
   IF ! hb_DirExists( cFolder )
      hb_DirCreate( cFolder )
   ENDIF
   
   IF ! hb_FileExists( cFolder + '\Teste.dbf' )
      dbCreate( cFolder + '\Teste', { { "COD", "N",  8, 0 }, { "DES", "C", 92, 0 } } ) 
   ENDIF

Como fazer o exemplo acima usando hbNetIo ?

Código: Selecionar todos

   // Pasta 'Temp' deve ser criada no path do hbNetIo (e não na raiz do disco em uso)
   ???
