Quisiera saber como abrir un nuevo form(formulario) cuando se termine de cargar la progressbar al 100%, no se como hacerlo, ya tengo el timer y la progressbar y asi, aqui dejo la parte del timer y del progressbar, necesito ayuda. Gracias
Uso visual studio 2012 y el lenguaje es C#
private void Form1_Load(object sender, EventArgs e)
{
timer1.Start();
}
private void timer1_Tick(object sender, EventArgs e)
{
PB1.Increment(1);
lblcarga.Text = PB1.Value.ToString() + "%";
}
No veo que cargues nada especial mientras el programa carga >:(
haz un simple (no tengo tengo teclado en condiciuones y no puedo escribir todos los simbolos).
if(int.parse(lblcarga.Text) ; 100)
{
lblcarga.text = int++;
}
else{
timer.enabled = false;
// empiezas el thread del nuevo form.
}
Por favor, a los dos, usad las etiquetas GeShi para insertar bloques de código. Leed Las normas del foro de programación.Cita de: PichusMR en 8 Noviembre 2015, 22:52 PMno se como hacerlo, ya tengo el timer
Empezamos mal asumiendo que todo se soluciona o se debe solucionar con un
Timer :P. De todas formas, la solución al código que actualmente tienes sería comparar el valor actual del progreso,
ProgressBar.Value, con el valor máximo, la propiedad
ProgressBar.Maximum.
PB1.Increment(1);
blcarga.Text = PB1.Value.ToString() + "%";
if ((PB1.Value == PB1.Maximum)) {
MessageBox.Show("Progreso finalizado.", "", MessageBoxButtons.OK);
}
Yo optaría por heredar y extender la class
ProgressBar para exponer un evento llamado
ValueChanged que se dispare cuando el valor o posición de progreso cambie, y entonces comodamente podriamos suscribirnos a dicho evento.
Ejemplo de uso en Vb.Net:
''' ----------------------------------------------------------------------------------------------------
''' <summary>
''' Handles the <see cref="ProgressBarExtended.ValueChanged"/> event of the <see cref="ProgressBarExtended1"/> control.
''' </summary>
''' ----------------------------------------------------------------------------------------------------
''' <param name="sender">
''' The source of the event.
''' </param>
'''
''' <param name="e">
''' The <see cref="ProgressBarExtended.ValueChangedEventArgs"/> instance containing the event data.
''' </param>
''' ----------------------------------------------------------------------------------------------------
Private Sub ProgressBarExtended1_ValueChanged(sender As Object, e As ProgressBarExtended.ValueChangedEventArgs) _
Handles ProgressBarExtended1.ValueChanged
Dim pb As ProgressBarExtended = DirectCast(sender, ProgressBarExtended)
If (e.Value = pb.Maximum) Then
MessageBox.Show("Progreso finalizado.", "", MessageBoxButtons.OK)
End If
End SubEjemplo de uso en C#:
/// ----------------------------------------------------------------------------------------------------

private void ProgressBarExtended1_ValueChanged(object sender, ProgressBarExtended.ValueChangedEventArgs e) {
ProgressBarExtended pb = (ProgressBarExtended)sender;
if ((e.Value == pb.Maximum)) {
MessageBox.Show("Progreso finalizado.", "", MessageBoxButtons.OK);
}
