How To Display a WFC Form in a Visual J++ Applet (288824)

SUMMARY

The WFCApplet.exe sample demonstrates how to load a Windows Foundation Classes (WFC) form in a Visual J++ 6.0 applet.

Note Because the Visual J++ graphical user interface (GUI) designer does not work for applets, you must create the form as a WFC control. You can only use WFC under Microsoft Windows operating systems with the Microsoft virtual machine for Java (Microsoft VM). Also, you cannot use WFC controls directly in an applet, or else the applet simply instantiates the form because there is no inherent relationship between the form and the applet. To use WFC controls, you must place the controls in a WFC container.

How to Use the WFCApplet.exe Sample

This sample demonstrates the use of WFC controls on a Java applet and how to install this applet into the Java Package Manager.

Note You do not put the WFC controls directly onto the applet area. You must create a WFC form and drop the controls on the form. When you run the applet, the Form window appears on top of the Microsoft Internet Explorer window.

This sample contains the Visual J++ 6.0 project, including two .htm files: Local.htm, which you use from the Visual J++ 6.0 Integrated Development Environment (IDE), and WFCApplet.htm, which you use for deployment to a Web server.

There are only two Java classes in this project: WFCApplet.java, which is a simple applet class that creates the WFC form, and WFCAppletForm.java, which is the WFC form class.

Using the WFCApplet.htm file, clients are prompted to install the Microsoft VM if they do not have the latest version. If they must update the Microsoft VM, the clients must also restart their computers after installation. Then, the two classes are installed into the Package Manager on the client computer to offer versioning, in the likely event that you will need to upgrade the package someday.

Caution After you run WFCApplet.htm, these classes are installed into the Package Manager and are located on the classpath before any new versions of the classes, even when you make subsequent changes through Visual J++ 6.0. To prevent this, go to the WINNT\Downloaded Program Files folder. Select and then right-click WFCApplet, click Remove, and then click Yes.
