Working with Controls in C#

In this Blog, we will see how to use ProgressBar control in a Windows Forms using Visual Studio 2005. We will also use Timer & BackgroundWorker in a forms.

ProgressBar : Displays a bar that fills to indicate to the user the progress of an operation.

Timer : Component that raises an event at user defined intervals.

BackgroundWorker : Executes an operation in a separate thread.

Let's Start to Windows Application.

Write code to btnLogin

if (txtLogin.Text == "ADMIN" && txtPass.Text == "PASS")
{
timer1.Enabled = true;
timer1_Tick(sender, e);
panel2.Enabled = true;
panel3.Enabled = true;
lblTime.Text = Convert.ToString(DateTime.Now.TimeOfDay).Substring(0, 8);
lblDate.Text = Convert.ToString(DateTime.Now.Date).Substring(0, 11);
}

{
MessageBox.Show("Please Enter Right password and username");
