Eu tentei já essa infomação logo no inicio do projeto, a finalidade desse projeto é fazer interação com outro software chamado LabelView que faz impressão de códigos de barra, o problema é que nas ultimas versões do LabelView, foi lançado uma versão que não tem compatibilidade com forms, e a linguagem homologada pra Desenvolvimento nesta empresa é VB6. Se utilizar Form o LabelView da problema. Entramos em contato com a fabricante do software, a informação que eles passam é que isso foi feito para impedir que outras softwares interajam com o interfaceamento do LabelView, porém nesta fábrica tem diversos operadores que interagem com o label view, e perdem cerca de 30 seg a cada produção, se eu eliminar esses 30 segundos perdidos, isso siginificará um aumento de produção de 20%. E 20% nesta Fábrica é uma diferença muito grande.

Mas pra não dizer que eu não testei o seu código, eu retirei os forms e testei apenas o módulo. conforme imagem em anexo.

E conforme faleu que havia testado, infelizmente não deu certo.

Grande amigo LVFIOROT, este é o meu projeto ele é assim mesmo, ele não abre pelo form ele só pode ser aberto pelo Módulo, Usando o código abaixo, obrigado por sua ajuda, e quero agradecer ao grande amigo MARCELO-TREZE que por sua vez apresentou uma solução final a qual posto aqui para que todos possam ver, além do link do Marcelo onde poderão baixar.

Obrigado amigo Marcelo.

Boa semana a todos.
