<Result> = GetTypeDefinition(<Element name>)
<Result>: Definition
Definition variable.
<Element name>: Character string
  • Name of the class or structure for which the definition should be retrieved.
  • Name of the window, page or report for which the definition should be retrieved.
Remarks

Retrieving the definition

If the class or structure is unknown, GetTypeDefinition returns a Null definition with a non-fatal error ("Invalid definition").
If the element is not allocated, GetTypeDefinition returns a Null definition with a non-fatal error ("Element not allocated").
The error cases can be processed:
  • by comparing the description to Null.
  • by checking the value of the ErrorOccurred variable.

Limitations

  • In a project, you cannot retrieve the definition of a class or structure coming from:
    • an external component.
    • an internal component.
  • In an external component, you cannot retrieve the definition of a class or structure coming from the host project.
Component: wd290vm.dll
