FieldInfo and Control WithEvents

[Nicolas]

How can I fixe my code which is working fine for csarp control but give me
trouble on vb control withevents
This code is compil in a separate dll

private Control getObject(string ControlName)
{
//return an handle of the control
try
{
if(ControlName != FormOwner.Name)
{
BindingFlags bf = BindingFlags.IgnoreCase | BindingFlags.Instance |
BindingFlags.NonPublic | BindingFlags.Public | BindingFlags.Static |
BindingFlags.GetField;
Type t = FormOwner.GetType();

----- PROBLEM HERE ---------
System.Reflection.FieldInfo fi = t.GetField(ControlName,bf) ;
----------------------------

object o = fi.GetValue(FormOwner);
return (Control)o;
}
else
{
return FormOwner;
}
}
catch
{
return null;
}
}

Thank you for the help
