Introduction to PowerBuilder

Creating a Library

To create a library or to manage objects within the library, you need to invoke the library painter by clicking on icon. By default, the library whichever has the Application object is displayed in the expanded mode, i.e., all the objects within the library are listed. It is similar to the 'File Manager' , where to start with you see directories. Once you double click on the directory, it would expand and display all the files within the directory. All other directories are listed, but not expanded. Same is the case with PowerBuilder. Library in which the application object resides is expanded and other PowerBuilder libraries are just displayed.

Libraries that are not being displayed in the expanded mode have library icon. Libraries in the expanded mode have library icon ( It is like a open library door ).

To create a library, select Library/Create from the menu or click on icon.

In Create Library dialogbox, select the appropriate directory (we advise you to have a directory named "workdir" and use that directory throughout the course) and provide product ( PowerBuilder automatically adds '.pbl' extension if you don't provide any ) for the File name prompt and click on the Save button. PowerBuilder prompts you for the comments. Provide Library for 'Product Management System' application and click on OK button. Now you can see the new library in the library painter. Close the Library Painter.
