Hi Adam,

There is "Form.MdiChildren" property that returns Form[].

If you want to check if your "MyMDIForm" is one of the
MdiChildren then you can iterate through them e.g.:

Form[] mdiChildren=this.MdiChildren;
for(int i=0; i<mdiChildren.Length; i++) {
if( mdiChildren is MyMDIForm ) {
// i-child is instance of MyMDIForm
mdiChildren.Activate(); // for instance
}
}

Cheers!

Marcin
