Si es en java 6 he escuchado que ya existe una clase que hace eso

[Tael Yang]

mejo necesitamos saber en que lenguaje porque nos queda como dificil adivinar

[Oesoto]

Eso se llama un Splash Screen.

En Visual Basic está el asistente para hacer Splash Screens. Yo tengo una con este código

Public NotInheritable Class SplashScreen1
Public count As Integer = 3

'TODO: This form can easily be set as the splash screen for the application by going to the "Application" tab
' of the Project Designer ("Properties" under the "Project" menu).


Private Sub SplashScreen1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
'Set up the dialog text at runtime according to the application's assembly information.

'TODO: Customize the application's assembly information in the "Application" pane of the project
' properties dialog (under the "Project" menu).

'Application title
If My.Application.Info.Title <> "" Then

Else
'If the application title is missing, use the application name, without the extension

End If

'Format the version information using the text set into the Version control at design time as the
' formatting string. This allows for effective localization if desired.
' Build and revision information could be included by using the following code and changing the
' Version control's designtime text to "Version {0}.{1:00}.{2}.{3}" or something similar. See
' String.Format() in Help for more information.
'
' Version.Text = System.String.Format(Version.Text, My.Application.Info.Version.Major, My.Application.Info.Version.Minor, My.Application.Info.Version.Build, My.Application.Info.Version.Revision)



'Copyright info
Timer1.Interval = 1000
Timer1.Enabled = True


End Sub


Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
count = count - 1
If count = 0 Then
Timer1.Enabled = False
Me.Visible = False
Form1.Visible = True
Me.Close()
End If
End Sub
End Class

y en un adjunto le dejo el ejemplo para Java. La clase que tiene el main es TestSplash.java

[Grissom.]

int main( int argc, char **argv )
{
QApplication app( argc, argv );
QPixmap pixmap( "splash.jpg" );
QSplashScreen *splash = new QSplashScreen( pixmap );
splash->show();
QMainWindow *mainWin = new QMainWindow;
...
app.setMainWidget( mainWin );
mainWin->show();
splash->finish( mainWin );
delete splash;
return app.exec();
}

Ese ultimo ejemplo es en C++/QT??

[Tael Yang]

Oesoto (http://www.laneros.com/member.php?u=7285) ese codigo se pone en un formulario, en un modulo de clase, en un modulo sencillo???

Yo aquí lo tengo en un proyecto como la clase SplashScreen1.vb y en el momento de la creación se le dice que va a ser de tipo SplashScreen.

En las propiedades del proyecto se le dice que cuando arranque la aplicación se haga con ese SplashScreen.

No se mucho de esto porque como VB maneja eso con asistentes entonces muchas de las configuraciones y hasta parte del código lo pone automáticamente.

Sí, así es.
