Class 'clsGetHeaderValue' cannot be indexed because it has no default property

I am getting a strange error when I try to build my solution. The error occurs when I am calling the oGetHeaderValue function and passing the parameters. 

Dim oGetHeaderValue As New clsGetHeaderValue

Dim returnString As String
returnString = oGetHeaderValue(strInvoiceNumber, strOrderNumber)

The error message is: Class 'clsGetHeaderValue' cannot be indexed because it has no default property.

The confusion is caused by the fact that VB.Net uses () for array indexing as well as method calls.

You're calling your instance oGetHeaderValue as if it's a method. It looks like you probably meant to call a function on it instead but missed out that bit. So maybe your code should be:

Dim returnString As String = oGetHeaderValue.YourMethod(strInvoiceNumber, strOrderNumber)

Where YourMethod is whatever method you wanted to call.

And just to clarify after reading your question again, oGetHeaderValue is not a function, it's an instance of a class that might contain functions and subs etc.
