PowerBuilder, as an excellent front-end database R D tool, is favored by many database developers. Currently, more and more databases are involved in multimedia applications, while PowerBuilder does not provide multimedia controls like VB and Delphi, it does not mean that multimedia cannot be developed using PowerBuilder. The following describes three methods fo

About PowerBuilder 9.0 How to modify the project name, the first to find three files, XXX.PBL, XXX.PBT, xxx.pbw three files, why to find this third file it? Because when you build a project with PowerBuilder 9.0, you first set up these three files, such as Can be seen, so modify the time just modify this is three files can, The steps are as follows: Select 123.PBT, right-click o

I started learning from the beginning of the year and was also the first language development tool I learned. During this long time, I learned a lot about some of her technologies. PB Is indeed engaged in MIS Develop efficient, fast, and powerful tools. As the earliest 4gl Development tools are characterized: 1. Integrated in Script OfSQL Query Language; 2. Originality Datawindow Technology, and Database The storage process can be used together to implement very powerful reports; 3. Omnipotent

1. PowerBuilder IntroductionPowerBuilder was a leader in the rapid development platform for Management software in the 1990 's, and was suitable for developing client/server architecture applications based on relational databases. Based on its patented DataWindow technology, PB Development database management software is more than 10 times times more efficient than other development platforms, and its advanced compilers make the program run fast.After

Four buffers of DataWindow In PowerBuilder, DataWindow is the object that the user front-end uses to store and manipulate data. In each DataWindow object, 4 two-dimensional tables are used as data buffers to store the data that is queried. In the DataWindow, the operation of the data processing system in the user is actually the modification and movement of it in these buffers, finally, when the user submits the database, the system forms the SQL in-

　 1. Preface In PowerBuilder, The datawindow technology is the core of Pb, so that Sybase even applied for a patent for it. Almost all operations on the data in the database are performed through the datawindow object. The creation of the data window object directly affects the advantages and disadvantages of the application. For many programmers who are new to PowerBuilder, the difference between datawind

1.3 PowerBuilder connection to the database The connection way of database front-end development tool and backstage database management system is a very important topic. PowerBuilder provides two ways to access the backend database, one through the ODBC standard interface, and the second through a dedicated interface to the backend database. ODBC's Chinese name is an open database connection, it is Micros

Recently, the ghost had the idea of jdbc, because it was necessary to integrate the oracle driver into the software. This is a common problem, but I am not prepared to solve it in a common way. The common method is to get a "simplified" oracle client (you need to write the Registry) or directly connect to the client from oracle (you need to configure the tnsname file) Or simply integrate the oracle odbc driver (requires registration and configuration) I used
