  Hey Guys I got it working already.../

  Hehehehe....

  Without threading... Below is my code for the child load event...

  private void PatientMasterList_Load(object sender, EventArgs e)

  {

  this.Show();

  //Application.DoEvents();

  ((Form1)this.MdiParent).progressBar1.Minimum = 0;

  ((Form1)this.MdiParent).progressBar1.Step = 1;

  ((Form1)this.MdiParent).progressBar1.Maximum = 200;

  //while (!this.Focus())

  //{

  //System.Threading.Thread.Sleep(100);

  for (int i = 0; i < ((Form1)this.MdiParent).progressBar1.Maximum; i++)

  {

  ((Form1)this.MdiParent).progressBar1.PerformStep();

  ((Form1)this.MdiParent).progressBar1.Value += 1;

  if (((Form1)this.MdiParent).progressBar1.Value == ((Form1)this.MdiParent).progressBar1.Maximum)

  {

  break;

  }

  }

  dataGridView1.DataSource = AccessDBase.dtGeneral(boObjects.cmdSQL, "tblSample");

  bindingNavigator2.BindingSource = new BindingSource(AccessDBase.dsGeneral(boObjects.cmdSQL, "tblSample"), "tblSample");

  if (((Form1)this.MdiParent).progressBar1.Value == ((Form1)this.MdiParent).progressBar1.Maximum)

  {

  ((Form1)this.MdiParent).progressBar1.Value = 0;

  }

  }

  Thanks Chris Vega and Faha Mukhtar....

  Dim t As ToolStripProgressBar = StatusStrip1.Items("ToolStripProgressbar1")
  
  For i As Int16 = t.ProgressBar.Minimum To t.ProgressBar.Maximum
  Application.DoEvents()
  System.Threading.Thread.Sleep(100)
  t.ProgressBar.Value = i
  Next

  Chris, the scenario is this: I have an MDIParent Form with menu strip in it. Whenever I want to click a menu item in the menustrip control, I want the toolstripprogressbar to increment its value so that the user will know that the application is doing something...

  Thank you for your time Chris Vega.

  Chris, does this mean that I have to get a BackgroundWorker component and create another thread

  To be honest, I have no clear understanding yet of how multithreading works. I didnt get into that topic because I have read an article that it is risky..

  Chris Thank you so much for ur time... Do you have a sample application that does the same thing

  1. When I click a MenuItem, I am loading a form.
  2. When I am in the process of loading the child form, I want my progress bar to start working.

  Chris Vega, I really need your help, I think u have worked on this kind of problem before..

  Thanks again for ur time...

  Chris It worked but my application hunged up...

  Here is my code:

  //MDIParent

  private void patientsToolStripMenuItem_Click(object sender, EventArgs e)

  {

  frmPM.MdiParent = this;

  frmPM.Show();

  }

  //Child Form Load event

  private void PatientMasterList_Load(object sender, EventArgs e)

  {

  Application.DoEvents();

  ((Form1)this.MdiParent).progressBar1.Minimum = 0;

  ((Form1)this.MdiParent).progressBar1.Step = 1;

  ((Form1)this.MdiParent).progressBar1.Maximum = 100;

  while (!this.Focus())

  {

  ((Form1)this.MdiParent).progressBar1.PerformStep();

  }

  dataGridView1.DataSource = AccessDBase.dtGeneral(boObjects.cmdSQL, "tblSample");

  bindingNavigator2.BindingSource = new BindingSource(AccessDBase.dsGeneral(boObjects.cmdSQL, "tblSample"), "tblSample");

  this.Show();

  }

  Hi Franco,
  
  A couple of questions:
  
  1. When you click a MenuItem, are you loading a form
  2. When you load a form, are you doing something else before the form get displayed on to the screen
  
  If your answer to 1. and 2. is both yes, then you should make your progressbar accessible outside the MDIForm, hence you're accessing it from the MDIParent:
  
  

  // *value* should be replaced by actual value ((MyMDI)this.MDIParent).MyProgressBar.Value = *value*;

  
  
  And if you want this to be done while the form is loading, then call the Show method of the form inside the Form_Load event:
  
  

  private void Form1_Load(object sender, System.EventArgs e) { // Display the form to the screen this.Show(); Application.DoEvents(); // Do your thing here that requires progress report . .. ... ((MyMDI)this.MDIParent).MyProgressBar.Value = *value*; }

  
  
  Hope this helps,
  
  -chris
