How do i assign values to a structure element ??

I'm a newbie with Vb.NET so please excuse me if this is a stupid quetion.

I have declared a structure:

Structure ClientRecord
Public Client_ID As Integer
Public Client_Initials As String
Public Client_Surname As String
End Structure 'ClientRecord

I also have declared a property which is of this type of the structure:

Public Property Client() As ClientRecord
Get
Return FClient
End Get
Set(ByVal Value As ClientRecord)
FClient = Value
End Set
End Property

Now, in another form,i wish to set the values contained in the property
Client:

frmPolicy.Clien t.Client_ID = CInt(lblClientI D.Text)

HOWEVER - I GET THE ERROR:
'Expression is a value and therefore cannot be the target of an assignment".

HOW SHOULD I DO THE ASSIGNMENT?

Any help would be most welcome!

Thanks

Dont worry guys - I found a better solution by declaring the ClientRecord
datatype as a class instead of a structure. Now i dont have that probelm
anymore.

While i've found a solution i still dont understand what was wrong before
with the code i had, so any comments will still be welcome ...

thanks

When it's a structore the property will return a copy of the FClient
value, and when you assign the Client_ID you would just end up
modifying that temporary copy.

When it's a class you get back a reference to the same object and any
changes you ake affects FClient as well.

I am finding that altering and affecting values in elements in multidimensional arrays is a huge pain in the ass. I cannot seem to find a consistent way to assign values to arrays. Foreach would clearly be the most efficient way to do it, but it only works on a copy of the original array and not the original (which is counter intuitive in my estimation). Using each doesn't work consistently either. Not only that, it's unduly complex for...

I am so lost on this one. Dim Ary as Integer = New Integer(4) {0,1,2,3} FAILS with the error: Array initializer has 1 too few elements. So I try Dim Ary as Integer = New Integer(3) {0,1,2,3} Since arrays start at 0 (I am thinking)
