            this.serialPort.PortName = comPort;
            this.serialPort.BaudRate = 9600;
            this.serialPort.Parity = Parity.None;
            this.serialPort.DataBits = 8;
            this.serialPort.StopBits = StopBits.One;
            this.serialPort.Handshake = Handshake.RequestToSend;
            this.serialPort.DtrEnable = true;
            this.serialPort.RtsEnable = true;

        {
            string messages = null;
            messages = sms;
            if (this.serialPort.IsOpen == true)

This is not a good question - we cannot work out from that little what you are trying to do.

This part of source does not indicate any call to Form2/splashform neither a Close() command to it.

Member 9411249 21-Nov-12 9:15am

this is the Form2 opening a form3

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace WindowsFormsAppDAL
{
public partial class Form2 : Form
{
public Form2()
{
InitializeComponent();
}
Form3 f3 = new Form3();

private void timer1_Tick(object sender, EventArgs e)
{

if (progressBar2.Value < 100)
{
progressBar2.Value += 2;
}
else
{
timer1.Stop(); // Before calling f2.ShowDialog(), stops the timer event
Hide();
f3.ShowDialog();
Close();
}
//progressBar1.Increment(1);

}
}
}

this is the form3 opening a Form2

using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace WindowsFormsAppDAL
{
public partial class Form3 : Form
{
public Form3()
{
InitializeComponent();
}

private void applicationToolStripMenuItem_Click(object sender, EventArgs e)
{
Form1 fm2 = new Form1();

fm2.Show();
}
}
}

my Application is in form2

Next time please use the widget "improve question" and add the code snippet to your message. It is easy to read there between code block than here as comment

Please, bear in mind that we only get to work with what you tell us - since you haven't told us how you show your splash screen, or where and how you use your SmsClass, we can't tell what the problem is.
You need to add the relevant code fragments, or we have to guess, and that doesn't work too well! :laugh:

Thank you!

The problem is pretty simple to see (it may be harder to work out a fix)

C#

timer1.Stop(); // Before calling f2.ShowDialog(), stops the timer event
Hide();
f3.ShowDialog();
Close();

ShowDialog is a modal or blocking call - it does not return until the form it is called on is closed. So no further events happen in your Form2 class until the instance of Form3 (the splash screen) has done it's job, and closed. So not progress display, not messages, no UI updates at all.

Instead of that, add a handler for the Form3.Closed event, and use that to Close Form2. Just use f3.Show() instead of f3.ShowDialog() and remove the Close after it - if you close form2 after displaying form3, it will also destroy the form3 instance, since it is declared as a form2 class level reference.
