This is an example of an application with multiple window management and a dynamic smart browser with the search field option. A customised SDO populates a calculated field and performs some field population when a new row is added or created. Includes the following files: wMain,wOrder.w, wDept.w, dDept.w, dOrder.w

This code enables Crystal Reports to connect to a Progress AppServer, run 4GL code on that AppServer, and use the resulting TempTable as data for a report layout. It works with Progress 9 and 10 (OpenEdge), and with Crystal Reports 9 or 10. Minimum requirement is Crystal Reports Advanced, this offers a Java connection.

Business Application programming using Relational Data Structures in all environments GUI, Web and CHUI, almost always involve the representation of Groups and its Members. These Group/Member relationships could be a Group of Customers by Sales Region, the Users in a particular Security Group, the States that belong to a Country, etc. There are various approaches to presenting this association between Groups and its Members, depending on the nature of the application, the programming and UI environment, and other user requirements. One of the most common presentation methods, used under GUI, Web and CHUI environments is known as the Left-to-Right method. Under this presentation methodology, the user is presented with a list of all potential Members for a Group on the Left and the current selected Members in the Group on the Right. This article provides an easy to use Temp-Table approach to the Left-to-Right method, whereby the developer can simply replace the custom fields in the Temp-Table (in the example code) to satisfy the needs of his/her application.

The Event Driven UI Model is based on Widgets (Fields) Buttons, Fill-Ins, Combo-Boxes, etc., that reside in a Window (in Progress a Field Group, which in turn resides in a Frame, whose parent could be a Window). Thus, the lowest and most comprehensive level of information validation can only be done at the Field Level. Validation encompasses, both, the actual checking of the information, and also the Security associated with the Field. If the user is not allowed to work with certain Fields on the Window, then those Fields should not be enabled for that user, thereby, reducing the possibility of invalid information from entering into the Database. The Field Level Validation/Security Approach presented in the article is based on the use of SUPER-PROCEDURES (Internal Procedures in them) and associating them with the SESSION Handle, Persistent Triggers, Walking the Widget-Tree, PRIVATE-DATA of Widgets, PROGRAM-NAME(), Text Validation Files (.Val), and Temp-Tables.
