Avoid multiple Process Bar when Re - executing

Farhan Shariff

I have a application in which I use a process bar which starts after I click Start button (Start button is disabled after I click ) and once the process is complete the start button is enabled.

when I click start again there are 2 process bars I just want one process bar every time I re- execute

button1.Enabled = false;

pBar = new ProgressBar(); // now assigning to field

Controls.Add(pBar);

pBar.Name = "ProgresBar1";

pBar.Dock = DockStyle.Bottom;

pBar.Style = ProgressBarStyle.Marquee;

pBar.MarqueeAnimationSpeed = 10;

pBar.Width = 100;

pBar.Height = 30;

pBar.Minimum = 0;

pBar.Maximum = 100;

pBar.Value = 100;

//-------------------------------------------------

System.Threading.Thread.Sleep(10000);

//--------Statements----------------------------------------

//------------------------------------------------

pBar.Style = ProgressBarStyle.Continuous;

pBar.MarqueeAnimationSpeed = 5;

button1.Enabled = true;

Accepted answer
Just thinking about this some more, a better idea would be to just have a single instance of the ProgressBar control. You could then create this at design time and set those properties which don't change in the Properties Box.

Initially, you could set the Visible property to false and, when you want to use it, set it to true and also set the Style and MarqueeAnimationSpeed properties to their initial values.

if (pBar != null) Controls.Remove(pBar); works perfect. As you said it is a good idea to have a single instance I will try that :) Thanks a lot

You need to remove the previous ProgressBar from the controls collection before creating another one:

if (pBar != null) Controls.Remove(pBar);
