Answer 1

Probably there is an unneeded statement:

Imports System.Windows.Forms.VisualStyles.VisualStyleElement.

Try removing it or clarify the situation.

By the way, why do you need the For Each TB and If statements?

Answer 2

 
I code it in different way and it worked thanks any way 

 Sub CLEAR_ANY_GB_IN_FORM(GB As GroupBox, F As Form)
        Dim FF As System.Windows.Forms.Form = F

        Try
            For Each TB As GroupBox In FF.Controls.OfType(Of GroupBox)()
                If TB.Name = GB.Name Then

                    For Each Ck As PictureBox In TB.Controls.OfType(Of PictureBox)() : Ck.BackgroundImage = Nothing : Next
                    For Each Ck As CheckBox In TB.Controls.OfType(Of CheckBox)() : Ck.CheckState = CheckState.Unchecked : Next

                    For Each C As Control In TB.Controls
                        Dim r = C.Controls.GetType
                        Dim xx = C.GetType()
                        If C.GetType.FullName = "System.Windows.Forms.Button" Then Continue For
                        If C.GetType.FullName = "System.Windows.Forms.Label" Then Continue For
                        If C.GetType.FullName = "System.Windows.Forms.CheckBox" Then Continue For
                        C.ResetText()

                    Next

                End If
            Next
        Catch ex As Exception
        End Try
