                                Hello Osman,
                                I recommend that you take a look at http://www.regexlib.com/ - a wonderful library of regular expressions, including an online tester. This site may help you get a mask that meets your requirements because there is a really great number of different masks there. If this does not help, leave a comment here and we will try to build a corresponding mask for you.

                                  Attached is a small sample project demonstrating how to implement this functionality. The key point is to use an editor to represent only the protected part of the card number because our mask editors replace all characters with * in eemPassword mode.

                                  Card number length must be 16.
                                  First six number and last four number will be only decimal.
                                  In middle also only decimal but its must be not visible for securty.
                                  I want to visible like password char for securty.

                                  OK. Attached is a small sample project demonstrating how to implement this functionality. The key point is to use mask editors instead of labels to provide the editing functionality.
