Good rule of thumb: validate values before you use them. To offer any more help, we'd need to know how you're calling this method.

no i used webBrowser control in my form and i've written this code in progress changed event of webBrowser.

progress.Maximum =(Int32) e.MaximumProgress;
progress.Value =(Int32)e.CurrentProgress;

You are NOT validating that e.CurrentProgress is non-negative before attempting to assign it.

Could you tell me wih code?

[WingedPanther]

if ((Int32)e.CurrentProgress >= 0) {
  progress.Maximum =(Int32) e.MaximumProgress; 
  progress.Value =(Int32)e.CurrentProgress;
}
else
{
  //alert user that e.CurrentProgress is invalid
}
