Visual LANSA Framework

Usage Expectations

When using multiple Framework windows you need to consider resource utilization.

Every VLF window you open consumes additional resources. The amount of resource consumed depends significantly on the design of your application and the programming techniques you use. You need to balance resource utilization with resource availability on deployed systems.

There are some usage expectations you need to have about using Framework windows:

  • It would be reasonable for a user to have two or 10 or even 20 windows open, but not 50 windows.
  • Windows are heavyweight objects. They are intended to allow end-users to concurrently perform and switch between high level business tasks such working with Customers, Products and Orders concurrently. They are not intended to handle simple lightweight tasks such as handling an F4 prompt.
