INTERCALACAO DE PLATAFORMAS VB6 VB.NET
Boa noite pessoal, vejam só, estou querendo começar a utilizar vb 2010, mas me esbarro ainda na falta de tempo para programacao.. agora pergunto o seguinte, eu vi um sistema ai .. que por falta de te tempo de fazer o projeto inteiro em vb 2010, o cara conseguiu intercalar o sistema dele em vb6, e aos poucos ele foi migrando o sistema e os forms para vb2010, exemplo.. ele tinha o cadastro de clientes em vb6, ele conseguiu uma forma de quando clicasse no cadastro, ele ja abria a nova tela que ele fez em vb2010, gostaria de saber como fazer isso..
Eu acho que ele chama um exe passando parametros na parte do .net pelo shell do vb6 assim da para ir intercalando por partes ...já fiz algo parecido mais não por essa necessidade e sim pq o que eu precisava fazer era so em .net mesmo.
segue ai uma rotina que pode te ajudar .. ela executa o comando no shell e so sai depois de finalizado o executavel , coloca ela num modulo
