So what is the problem?

This is fine. You cannot make VB.NET check the types itself also. You have to write this code.

Not quite sure of your question as the code you show will work, however if you have controls inside a container like a tabcontrol you need to iterate those controls separately as they are not members of the container you are iterating.

Easiest way is to use a recursive function passing the container control as argument and calling itself when it find a control has children passing that control as argument.

Quick example (not tested written of the top of my head).

VB

public sub WalkControls(TopControl as Control)
   For Each x As Control In TopControl.Controls
       If x.HasChildren Then
          WalkControls(x)
       Else
'
' Do what you want to do with the control
'
       End If
   Next
End sub
