The code builds with no errors.
The locals window lists everything under OrderContext as "Nothing", 0.0 or "False" when it stop on the line which attempts to set address1.

Troubleshooting tips:

        Dim OrderContext As New com.nicusa.cdc.tpe2_ks.WSOrderContext

        OrderContext.customer.address.address1 = "1233 Test Dr."
        OrderContext.customer.address.city = "Test City"
        OrderContext.customer.address.state = "KS"
        OrderContext.customer.address.zip = "66999"

推荐答案

构造函数New com.nicusa.cdc.tpe2_ks.WSOrderContext是否也创建了一个customer实例，或者是OrderContext.customer Nothing?
我猜就是这样.因此，还要构造一个客户对象(可能还有一个地址对象)，并设置属性.

Does the constructor New com.nicusa.cdc.tpe2_ks.WSOrderContext also create an instance of customer, or is OrderContext.customer Nothing?
I guess that''s what happens. Hence, also construct a customer object, and likely also an address object, and set the properties.
