Updating a parent form from a subform


Subforms do not know about their parent form and there is no way to pass a reference of the parent form to a subform to "link" the two. Instead we have to go an unconventional route which is described in this recipe.

How to do it...

  1. Create a new form using the Object Designer.

  2. Add the following global variables:

    Name

    Subtype

    A

    Integer

     

    B

    Integer

  4. Add a global function named GetA that returns an integer with the following code:

    EXIT(A);
    
  5. Add a global function named GetB that returns an integer with the following code:

    EXIT(B);
    
  6. Add a global function named SetXMLDoc that takes in the following parameter:

    Name

    Type

    Subtype

    XMLDocParam

    Automation

    'Microsoft XML, v6.0'.DOMDocument60

  7. Add the following code to the function:

    XMLDoc := XMLDocParam;
    
  8. Add two textboxes to the form.

  9. Set the SourceExpr...
