使用32位JRE打开64位Windows的虚拟键盘

Question

I need to open the Windows's virtual keyboard from my application, which will be deployed using Eclipse RCP on the windows 32 bit platform (ie win32 JRE).

Following the answers to the post open the Windows virtual keyboard in a Java program , the applications does so correctly on a 32 bit Windows OS, but refuses to work on a 64 bits Windows OS.

The solution I am using is the following ones:

//          String sysroot = System.getenv("SystemRoot"); //$NON-NLS-1$
//          Runtime.getRuntime().exec("cmd.exe /c "+sysroot + "\\system32\\osk.exe /n"); //$NON-NLS-1$ //$NON-NLS-2$
            Runtime.getRuntime().exec("osk");

Is there a way to fix this without using a 64 bit deploy? (which I can't create, as long as I am using a library that does not support this environment).

Thanks

Answer 1

Try this code. not sure it will work. but worth a try.

Desktop desktop = null;
if (Desktop.isDesktopSupported()) 
{
    desktop = Desktop.getDesktop();
}
String sysroot = System.getenv("SystemRoot");
desktop.open(new File(sysroot+"/system32/osk.exe"));

I am new to this Desktop class, and i would like to know if the class does the trick ;)

No. You won't be able to use the 64-bit library from a 32-bit Java app and/or a 32-bit OS. You'll have to deploy your app x64.

this is my workaround:

FileOutputStream fileOutputStream = new FileOutputStream(new File("C:/TEMP/RUN.BAT"));

        String file = "START C:/Windows/System32/osk.exe" + '\n'
                + "EXIT";
        fileOutputStream.write(file.getBytes());
        fileOutputStream.close();
        Runtime.getRuntime().exec("CMD /C START C:/TEMP/RUN.bat");
        Runtime.getRuntime().exec("CMD /C DEL C:/TEMP/RUN.bat");
