C # How to Implement the dual progress bar function in winform,

The progress bar prompts the user (we) about the status of the software being installed-percentage. When the installation software is too large, a progress bar prompt will appear very slow, then we can use two progress bars prompt. Displays the current progress and the overall progress. So how can this function be implemented? I would like to introduce the basic methods here and hope to help programmers and learn from them.

Open Microsoft Visual Studio 2010:

1. Create a solution

2. Add a new form-progress bar exercise

Form Layout

(1) Controls

There are 6 lable labels, 2 Progress bars, 1 button control, and 2 textbox Control;

(2) Basic Attributes

Lable label: Lbl_1; lbl_2; lbl_3; lbl_4; lbl_5; lbl_6;

Text: % overall progress of the current progress

Lbl_7 (used by the author to show examples)

Progressbar control: Pgb_1; pgb_2

Button Control: Text: installation!

TextBox Control: Txtb_1; txtb_2

Progress bar 1 Property settings

# Maximum: 500

Minimum: 1

Value: 1

Progress bar 2 Property settings

# Maximum: 100

Minimum: 1

Value: 1

Button Control click Event code

Progress bar 1 -- accumulate 500 times in a loop

(Note: add the "Application. DoEvents ();" statement)

Button Control click Event code

Progress bar 2 -- accumulate 100 times in a loop

(Note: add the "Application. DoEvents ();" statement)

Complete code

Namespace Design

{

Public partial class form2: Form

{

Public form2 ()

{

InitializeComponent ();

}

 

Private void btn_count_Click (object sender, EventArgs e)

{

For (int k = 1; k <= 100; k ++)

{

// Current progress

For (int I = 1; I <= 500; I ++)

{

Txtb_show_1.Text = I. ToString ();

Application. DoEvents ();

This. pgb_1.Value = I;

This. lbl_1.Text = (I/5). ToString ();

}

// Overall progress

Txtb_show_2.Text = k. ToString ();

Application. DoEvents ();

This. pgb_2.Value = k;

This. lbl_3.Text = k. ToString ();

}

}

}

}
