Question : "Progress Bar" form that can be called often throughout an application

I'd like a 'progress bar' that pops up in my application that offers some visual feedback to the user.
For example if I know a process has 5 steps, I can do something like this:

DoProgressBar(5 steps);

ProgressBarStatusMessage('Initiating connection to server...');

Then after each step:
IncrementProgressBar(1);
ProgressBarStatusMessage('Authenticating user');

...

IncrementProgressBar(1);
ProgressBarStatusMessage('Fetching products...');

...

IncrementProgressBar(1);
ProgressBarStatusMessage('Checking balances...');

etc

Perhaps somebody already has a unit and form that can do this?

Before you can introduce Windows Server 2008 domain controllers into existing Windows 2000 or Windows Server 2003 domains, you must prepare the forest and domains with the ADPREP utility. ADPREP.exe is a command-line tool that extends the Active Directory schema, and updates permissions as necessary to prepare a forest and domain for a domain controller that runs the Windows Server 2008 operating system.
