How to check if a windows form is already open, and close it if it is?

by

maybe this helps:

FormCollection fc = Application.OpenForms;

foreach (Form frm in fc)
{
//iterate through
     if (frm.Name == "YourFormName")
     {
         bFormNameOpen = true;
     }
}

Some code in the foreach to detect the specific form and it could be done. Untested though.
