The VB.NET Never-ending Progressbar now in C#

Sample Image - OSProgress.png


Sometimes you just don’t know how long something will take. Like when your wife says she’ll only be a few minutes in the grocery store…you know what I mean.

The standard ProgressBar that ships with Visual Studio is great for when you know how long something will take, or there is a way to determine just how many steps a process will have. But like the trip to the store with your wife, sometimes you just can’t know how long something’s going to take. That’s why I created this progress bar.

I finished this task with the System.ComponentModel.BackgroundWorker
You have progressbar which autoprogress set to true and visible set to false.
when user start the program, no one will see this progress bar. when user click a button, this progress bar visible is set to true and we call SpineUp() now.
Big Grin | :-D Big Grin | :-D
here is my code:
private System.ComponentModel.BackgroundWorker _backThread;
public Form1()
_backThread=new System.ComponentModel.BackgroundWorker();
this._backThread.DoWork += new System.ComponentModel.DoWorkEventHandler(this.ProcessNumbersBackgroundWorker_DoWork);
this._backThread.RunWorkerCompleted += new System.ComponentModel.RunWorkerCompletedEventHandler(this.ProcessNumbersBackgroundWorker_RunWorkerCompleted);


private void ProcessNumbersBackgroundWorker_DoWork(object sender, DoWorkEventArgs e)
//Do your work here

private void ProcessNumbersBackgroundWorker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
MessageBox.Show("Done background work!");

private void button4_Click(object sender, EventArgs e)


private void SpineUp()
