HOWTO: Disabling "Warning: Applet Window" Message

• Microsoft Visual J++, versions 1.0, 1.1

SUMMARY

When you create a frame from within a Java applet and run this applet outside DevStudio, the frame sizing is inconsistent and the following Warning message also appears in the frame's Status Bar:

   Warning: Applet window

MORE INFORMATION

The above Warning message doesn't appear when you run the applet from within DevStudio. To disable this message from appearing when you run the applet from outside DevStudio, you need to Cab&Sign your applet's class files.

The following steps show you how to reproduce this problem:

1. Create a default Java Applet using the Applet Wizard.

2. At the beginning of your project class, which extends the applet, include the following:

         Frame window;
   

3. In the init() function include the following code, which creates and shows the frame:

         public void init()
         {
           window = new Frame("A popup window");
           window.resize(150,150);
           window.show();
         }
   
   

4. Build the project.

5. Execute the project's HTML file from outside DevStudio.

6. This invokes the Browser and a Frame window with the title "A popup window" appears. The window, which is resized inconsistently, has the Warning message in its status bar.

REFERENCES

For more information on how to Cab&Sign your Java applets, please refer to the Cab&Sign sample that comes with the Visual J++ CD. This contains step-by-step instructions on how to create a CAB file with the Java Class files and how to create a Test Certificate and Sign the CAB file with your certificate. The Visual J++ CD also includes the CabDevKit and the Code Signing Kit that provides the necessary tools to CAB&Sign. These utilities can be found under Cab&Sign folder.
