(Resolvido)Código de barras

Matheus-vb6 · October 28, 2011

Boa tarde...

Estou tentando desenvolver um gerador de código de barras para ser lido por um leitor, porém, só utilizando fontes, o leitor não reconhece, precisa de uns separadores (segundo li no macoratti)

alguém tem ideia de como faço os separadores? ou como faço um codigo de barras q possa ser lido??

abraços

Resolvido depois de muitas e muitas pesquisas... fica o código pra quem quiser...

adicione um picture box com o nome pean e a propriedade autoredraw true... depois adicione 2 botões, 1 chamado cimprimir e o outro cguardar, por fim um textbox chamado txtean...


Dim W As String 'a cor W é a cor do picture1
Private Const N As String = &H0&
Private Const A As String = "A"
Private Const B As String = "B"
Private Const C As String = "C"

Private Function CorLinha(Digito As Integer, Numero As Integer, Posicion As Integer, NumeroLinea As Integer)
