Question

My application creates MDI Children programatically. I have a frmBrowser as an MDI Child which I create multiple instances of. There are several other MDI children in the MDIParent. How do I only cycle through the frmBrowser MDI children?

For Each Child As frmBrowser In frmMain.MdiChildren
    'perform action on child
Next Child

The code above gives an error for all the Child that aren’t of the type frmBrowser.

Answer 1

Try this:

For Each Child As frmBrowser In frmMain.MdiChildren.OfType(Of frmBrowser)()
    'perform action on child
Next Child
