Window Management in Forms

Summary

The purpose of this chapter was to highlight some tips and techniques for advanced Forms GUI programming. The topics under discussion were the suppressing of default master-detail behavior, toggling between Immediate and Deferred coordination, preventing a query in a block from execution if it returns no records, using form and global variables , base tables, and record groups, and the persistent confusion between DO_KEY and the corresponding KEY- trigger. This chapter also presented a simple solution for creating a customized sign-on form. Last, I discussed Windows management with regard to standard window operations such as Resize, Reposition, and Close.
