B4J Question Problem sending the @ character

[claudiob4]

Hi all, I can't send the @ character with any of the steps below. Does anyone have the solution?
Thank you


Dim robot As JavaObject
robot.InitializeNewInstance("javafx.scene.robot.Robot", Null)

Dim KeyCode As JavaObject
KeyCode.InitializeStatic("javafx.scene.input.KeyCode")


robot.RunMethod("keyPress", Array(KeyCode.GetField("AT")))
robot.RunMethod("keyRelease", Array(KeyCode.GetField("AT")))
'not work

robot.RunMethod("keyPress", Array(KeyCode.GetField("ALT_GRAPH")))
robot.RunMethod("keyPress", Array(KeyCode.GetField("AT")))
robot.RunMethod("keyRelease", Array(KeyCode.GetField("AT")))
robot.RunMethod("keyRelease", Array(KeyCode.GetField("ALT_GRAPH")))
' not work

robot.RunMethod("keyPress", Array(KeyCode.GetField("ALT")))
robot.RunMethod("keyPress", Array(KeyCode.GetField("AT")))
robot.RunMethod("keyRelease", Array(KeyCode.GetField("AT")))
robot.RunMethod("keyRelease", Array(KeyCode.GetField("ALT")))
'not work

The ASCII code of the @ character is 64, but a PC uses not one, but 2 bytes for a character. For a PC with a numeric keypad, hold down the left ALT key and then tap the numeric keypad 0064 for the @ character. Did you try the B4J Library jAWTRobot - invoke keyboard and mouse events, etc...?

Perhaps this code is what you need

Dim robot As JavaObject
robot.InitializeNewInstance("javafx.scene.robot.Robot", Null)

Dim KeyCode As JavaObject
KeyCode.InitializeStatic("javafx.scene.input.KeyCode")
   
robot.RunMethod("keyPress", Array(KeyCode.GetField("SHIFT")))
robot.RunMethod("keyPress", Array(KeyCode.GetField("DIGIT2")))
robot.RunMethod("keyRelease", Array(KeyCode.GetField("DIGIT2")))
robot.RunMethod("keyRelease", Array(KeyCode.GetField("SHIFT")))

Thanks for the reply. I work on an Italian keyboard and unfortunately this sequence produces the character " but not @. On my keyboard the combination is ALT_GRAPH ò . But the character ò does not have a keycode in the table. How to do it?

The problem could be that you can use a country specific keyboard in combination with an other language while javafx looks to the language of the OS, not to the connected keyboard.
[CODE lang="java" title="How to check current keyboard language in java"]import java.awt.im.*;
public class _Test
{
public static void main(String[] args)
{
InputContext context = InputContext.getInstance();
System.out.println(context.getLocale().toString());
}
}[/CODE]
What keyboard language is reported?

Try this code

    robot.RunMethod("keyPress", Array(KeyCode.GetField("ALT")))
    robot.RunMethod("keyPress", Array(KeyCode.GetField("NUMPAD0")))
    robot.RunMethod("keyRelease", Array(KeyCode.GetField("NUMPAD0")))
    robot.RunMethod("keyPress", Array(KeyCode.GetField("NUMPAD6")))
    robot.RunMethod("keyRelease", Array(KeyCode.GetField("NUMPAD6")))
    robot.RunMethod("keyPress", Array(KeyCode.GetField("NUMPAD4")))
    robot.RunMethod("keyRelease", Array(KeyCode.GetField("NUMPAD4")))
    robot.RunMethod("keyRelease", Array(KeyCode.GetField("ALT")))

The Italian keyboard code for a @ character is 0264, so teddybear code must be:

[CODE lang="b4x" title="Italian @ code"] robot.RunMethod("keyPress", Array(KeyCode.GetField("ALT")))
robot.RunMethod("keyPress", Array(KeyCode.GetField("NUMPAD0")))
robot.RunMethod("keyRelease", Array(KeyCode.GetField("NUMPAD0")))
robot.RunMethod("keyPress", Array(KeyCode.GetField("NUMPAD2"))) ' <== select Italian keyboard
robot.RunMethod("keyRelease", Array(KeyCode.GetField("NUMPAD2"))) '
robot.RunMethod("keyPress", Array(KeyCode.GetField("NUMPAD6")))
robot.RunMethod("keyRelease", Array(KeyCode.GetField("NUMPAD6")))
robot.RunMethod("keyPress", Array(KeyCode.GetField("NUMPAD4")))
robot.RunMethod("keyRelease", Array(KeyCode.GetField("NUMPAD4")))
robot.RunMethod("keyRelease", Array(KeyCode.GetField("ALT")))[/CODE]

All of these solutions don't work. However I found a way to fix it using the jAWTRobot.

[CODE lang="b4x" title="send @" highlight="5"] Dim jRobot As AWTRobot

'Suppose we need to send a string containing the character @'

jRobot.RobotPaste("[email protected]",50)
[/CODE]

Thanks for your attention
