Invoking a method of one form from another at the same time

Question

I am developing an application which displays files and folders in a listview like our Desktop. User can select as many items from the listview and delete .

I want to delete the items with a progress bar like our desktop. For that I am keeping all the selected items in an arraylist and passed that arraylist to another small form having progress bar. In this form I am deleting the items in separate thread from the database and after complition I am loading the listview with new items.

Its working fine.

Now what I want is that as the progress bar shows one items gets deleted the same item
should be removed from the main form at the same time . As like our desktop .

Now since here I have two forms . One form is actually deleting the items from the database with a progress bar . I need some way to invoke some method in my main form which will keep removing the items from the listview at the same time.

How can i invoke a method of one form from another form.

If we see our windows as progress bar shows items getting deleted the actual items from the listview also keeps removing...

plz help...

since it's being done in another thread on the other form I would consider creating a user event that you fire on the main form every time you delete an item from the child form. Otherwise (another option) you'll need to create a delegate on the mainform and use Invoke or BeginInvoke so as not to step on the Windows Thread. You'll need to pass a this reference from the mainform to the child form so the child form knows how to call invoke on the main form.
