title: Readsoft Invoices COM-plugin - How to change an Invoice Field Value
body: <p>I want to change the value of an invoice field of the current invoice being processed by the interpreter.</p>
  
  <pre><code>objInvoice = objEHApplication.CurrentInvoice
  Dim aInvField As InvoiceField
  aInvField = objInvoice.Fields.Item("theFieldName")
  aInvField.Value = "someValue"   '// &lt;- ReadOnly
  </code></pre>
  
  <p>The problem is that when trying to set the value property, the compiler says it's ReadOnly.</p>
  
  <p>What is the correct way to change/set an invoice field value from an Eyes&amp;Hands COM-plugin?</p>
