#93336 Resposta escolhida

tente fazer no load do form principal um programa para mudar a resolução, e quando o usuário sair, volta a resolução padrão!

Se quiser o Código, posso lhe arrumar...

Dim b As Long

[txt-size=4]'agora este é o código do form[/txt-size]

Dim ResX As Single
Dim ResY As Single
Dim OldResX As Single
Dim OldResY As Single
Dim Resolucao As Boolean


'logo abaixo você chama o procedimento:

Call ChangeRes(640, 480)

'muda para a resolução 640x480, você escolhe qual resolução

'use o Load e Unload do form

Espero ter ajudado!
