Hi,

i need to use the latest API in live mode but pin bypass is only available for static IPs which is unsuitable for me.

I remember seeing an example somewhere on how to use the IClient getCaptchaImage to use standalone API with pin verification and then start a strategy. I can't find it anymore though

Is there an example available or can you please provide a simple one? Just to get a connection with pin verification running to start a strategy. No other gui needed.

Thanks a lot

Probably very bad code but it works

JForex API Main.java Example:

the changed lines are:

...
PinDialog test=new PinDialog(null,client,jnlpUrl);

LOGGER.info("Connecting...");
//connect to the server using jnlp, user name and password
client.connect(jnlpUrl, userName, password,test.pinfield.getText());
...

Maybe Dukascopy can post their Pin/Captcha Dialog source?

Your example already successfully uses the captcha, what additional information do you need?

I dont need anymore information. I only thought it would make a nice addition to the wiki and my code is not what i would call well written.

this method is good. but it needs to input PIN code manually everytime.

how can I do not input PIN code by hand? it is useful to create an automatic trade system.

I have no static IP. I believe most of us have no static IP.
could Duk create a new policy to disable PIN under the condition that one requests???

The Captcha image itself includes an image of a "Reload" and a "Cancel" as part of the rectangular image. I'm sure there's a way to somehow put an "image map" type of event handler which will allow users to click on the lower left portion of the image and generate a Reload event, and on the lower right to generate a Cancel event, but I'd rather not have to work out that logic.

If someone has logic to manage the Captcha image, then please make a contribution.

It is confusing to a user to have this "Reload" and "Cancel" part of the image (which does not naturally respond to a click), and also to have additional real JButton controls which implement Reload and Cancel operations.

Yes, I know I could blank out portions of the image, etc., and I could also enhance the captcha image myself, etc., but please post some proper handling code so everyone will benefit.

By adding a mouse listener as shown below, simple click handler functions can be achieved.

Here is a simple "hack" based upon the dimensions of the image I've seen:

      captcha_image.setIcon(new ImageIcon(client.getCaptchaImage(jnlpUrl)));
      captcha_image.addMouseListener(new MouseAdapter() {
          public void mouseClicked(MouseEvent me) {
             int x = me.getX();
             int y = me.getY();
            //System.out.println("CLICKED x: "+x+" y: "+y);
            if (y>=94) {
               if (x<=75) {
                  //System.out.println("RELOAD");
                  myReload(); // you must implement
               }
               else if (x>=164) {
                  //System.out.println("CANCEL");
                  myCancel(); // you must implement
               }
            }
          }
       }); 

Hope this helps someone. It's not much, but it works.
