my code
Private Sub optFullTime_Che ckedChanged(ByV al sender As System.Object, ByVal

optContractor.C heckedChanged, optCurrent.Chec kedChanged,
optFormerEmploy ees.CheckedChan ged, optTemporary.Ch eckedChanged,
optPartTime.Che ckedChanged
Select Case sender.GetType. Name ' Returns RadioButton
'If I turn off option strict I can use sender.Name and it works but I know
I'm overlooking something trivial. So what I need is to know the name of
the control that was pressed. What am I overlooking?

William,
Use DirectCast to cast the sender object into a known type. You could use
either RadioButton or Control if you wanted just the name.
Something like: Private Sub optFullTime_Che ckedChanged(ByV al sender As System.Object,
ByVal e As System.EventArg s) Handles optFullTime.Che ckedChanged,
optContractor.C heckedChanged, optCurrent.Chec kedChanged,
optFormerEmploy ees.CheckedChan ged, optTemporary.Ch eckedChanged,
optPartTime.Che ckedChanged
Dim opt As Control = DirectCast(send er, Control)
Select Case opt.Name
or
Select Case DirectCast(send er, RadioButton).Na me
I normally use the first as invariable I need mutliple accesses to the
sender.
Hope this helps

vMike,
The way I view them is:
CType = Convert type
DirectCast = Cast type
Convert type will use conversion routines to physically change an object
from one type (String) into an object of a different type (Integer). If the
object is already that type a simple cast is done, however extra checks are
made to see if a conversion can occur (read as extra overhead).
Dim i As Integer
Dim s As String
i = CType(s, Integer)
Cast type allows an assignment of an object of a specific type to that
specific type, where the object is currently in a variable of a compatible
type, by compatible type I mean a base type. Or the specific type is an
Interface, and the object implements the interface. DirectCast is important
when using Option Strict On. You are using Option Strict On! Correct!
Dim o As Object = New Form1()
Dim frm As Form1
frm = DirectCast(o, Form1)
The following articles explains, among other things, conversions vs casting: http://msdn.microsoft.com/library/de...tinternals.asp
Normally I use DirectCast, unless I have to use CType. I have to use CType
when DirectCast causes a compile error. Or I am actually doing a conversion.
Hope this helps

Yes Option Strict is On for sure!! I think I will change my ctype's to
directcast's were possible. Looks like it will be a little less overhead.
