InvokeMember for STRUCTURE and CLASS.

[Qwert]

Hello,

why does the following code work for a CLASS, but not for a STRUCTURE?
(The first MsgBox returns '0,0', but I expected it to be '100,0'.)
(The second MsgBox returns 'Hello', as expected.)
REM Code in a button click event:

Dim objObject, objValue As Object

objObject = Activator.CreateInstance(GetType(System.Drawing.Po int))
objValue = 100
objObject.GetType.InvokeMember("X", System.Reflection.BindingFlags.Static Or
System.Reflection.BindingFlags.Instance Or
System.Reflection.BindingFlags.Public Or
System.Reflection.BindingFlags.NonPublic Or
System.Reflection.BindingFlags.SetProperty, Nothing, objObject, New Object()
{objValue})
MessageBox.Show(objObject.X.ToString & "," & objObject.Y.ToString)

objObject = Activator.CreateInstance(GetType(System.Windows.Fo rms.TextBox))
objValue = "Hello"
objObject.GetType.InvokeMember("Text", System.Reflection.BindingFlags.Static
Or System.Reflection.BindingFlags.Instance Or
System.Reflection.BindingFlags.Public Or
System.Reflection.BindingFlags.NonPublic Or
System.Reflection.BindingFlags.SetProperty, Nothing, objObject, New Object()
{objValue})
MessageBox.Show(objObject.Text.ToString)
Thanks.
