problema resolvido...se alguem quiser o codigo está aí...

NO ACTIVE DO FORM você COLOCA A SEGUINTE ROTINA

XResolucao = GetSystemMetrics(0)

YResolucao = GetSystemMetrics(1)

If XResolucao = 800 And YResolucao = 600 Then EXIT SUB

Call Resolucao(800, 600)

AGORA O CODIGO ABAIXO você INSERE NO MÓDULO DO SEU PROJETO OU CRIA UMA DLL PARA ISTO.
