PowerBuilder contains a number of built-in common dialogs that can be used within your own applications. What do you do when one of these dialogs meets most, but not quite all, of the functionality you need? Do you simply accept the limited functionality? Do you write your own dialog from scratch to replicate them and add the additional functionality (a maintenance headache)? There is a third option. You can simply use the dialog that PowerBuilder provides and modify it at runtime to provide just the additional functionality that you need. The dialogs PowerBuilder provides include: The GetFileOpenName, GetFileSaveName, ChooseColor, GetFolder, PrintSetup, and PrintSetupPrinter system function dialogs The DataWindow Control SaveAs, SetFilter, and SetSort function dialogs The DataWindow object DataWindow.Print.Prompt attribute dialog The ubiquitous MessageBox dialog For...

DataWindow.NET How To: DataWindow Formatting

Last month we saw how DataWindow.NET technology can be a benefit when used for data presentation and data access in a Windows Forms (WinForms) application. This month we're going to look at how DataWindow.NET technology is a simpler but more powerful way of formatting data in the presentation layer. Once again, we'll be taking a sample application provided by Microsoft for .NET and implementing it using DataWindow.NET technology. In this case, we're using the Visual Basic .NET Code Sample: DataGrid Formatting sample application available at www.microsoft.com/downloads/details.as... (more)

Implementing the Microsoft Rich Edit Control

As we mentioned in Part 1 (PBDJ, Vol. 12, issue 7), we needed to implement spell checking in the rich edit fields in our application (see Figures 1 and 2). To do that, we got a license for the Sentry Spelling Checker Engine from Wintertree Software (www.wintertree-software.com). The utility is easily implemented and works quite well on standard Rich Edit controls. However, the PowerBuilder Rich Edit control is an OEM version of an old third-party control that was popular before Microsoft introduced its Rich Edit control to the common controls. As a result, the messages and funct... (more)

OLE - Extending the Capabilities of PowerBuilder

This two-part article provides a primer on OLE, some practical examples of its use, and demonstrates some methods for addressing the limitations of PowerBuilder's implementation of OLE. In Part 1 I provided some background information for OLE and discussed the use of custom controls, in Part 2 I talk about OLE Automation and OLE objects. OLE Automation OLE Automation is the interface through which one application (e.g., Microsoft Outlook) makes the methods, properties, and events of its objects (e.g., Folders, Messages, Address Book) available for use within another application...

Deploying PowerBuilder Components to JBoss

The PowerBuilder Application Server Plugin (PASP) is a new product offering from Sybase. It's currently in beta as part of the EAServer 6.0 beta; however, when released it will be distributed as a separate product. The PASP allows PowerBuilder developers to deploy PowerBuilder components to third-party application servers (JBoss, WebSphere, WebLogic, etc.), much the same as they can with EAServer today. This is of particular importance in companies that have already standardized on a non-EAServer application server. Another important feature of the new product is the proxy serve... (more)
