Hi all.
I need to write a byte value to registry using java.


I use this code in vb.net.

 Dim RegKey As Microsoft.Win32.RegistryKey =Microsoft.Win32.Registry.CurrentUser.CreateSubKey("Software\Microsoft\Internet Explorer\Main")
Dim IEDispBinarySetting As Byte() = {&H2C, 0, 0, 0, 2, 0, 0, 0, _
                                                3, 0, 0, 0, &HFF, &HFF, &HFF, &HFF, _
                                                &HFF, &HFF, &HFF, &HFF, &HFF, &HFF, &HFF, &HFF, _
                                                &HFF, &HFF, &HFF, &HFF, 0, 0, 0, 0, _
                                                &H1E, 0, 0, 0, &H1D, 3, 0, 0, _
                                                &HDE, 2, 0, 0}

 RegKey.SetValue("Window_Placement", IEDispBinarySetting)

The first thing you need to do is to ensure that you can get to the right key. The Preferences api is very restricted in that respect

thank you for everyone and sorry for late.


i made a program from those sample.
like this

 private static byte[] toCstr(String str) {
                byte[] result = new byte[str.length() + 1];

                for (int i = 0; i < str.length(); i++) {
                  result = (byte) str.charAt(i);
                }
                result[str.length()] = 0;
                return result;
              }


      byte[] a=toCstr("&H2C, 0, 0, 0, 2, 0, 0, 0, 3, 0, 0, 0, &HFF, &HFF, &HFF, &HFF, &HFF, &HFF, &HFF, &HFF, &HFF, &HFF, &HFF, &HFF, &HFF, &HFF, &HFF, &HFF, 0, 0, 0, 0, &H1E, 0, 0, 0, &H1D, 3, 0, 0, &HDE, 2, 0, 0");
    Advapi32Util.registrySetBinaryValue(WinReg.HKEY_CURRENT_USER, "Software\\Microsoft\\Internet Explorer\\Main", "Window_Placement", a);
