Assignment3A: Diagnosis Checker: For years, patients have used websites like WebMD to pre-diagnosis themselves with a variety of illnesses before meeting with a doctor. As you might imagine, medical professionals believe this can lead to incorrect treatment. To combat this, a local hospital has asked you to develop a program that will help patients check if their symptoms match the online diagnosis. You will prompt the user to enter their illness. Based on this input, you will ask them if they are experiencing certain symptoms. Depending on their answer, your program will indicate if the Internet diagnosis is likely to be correct or not. The decision chart is shown below: • ● ● HGPS 0 Do they have brittle bones? If no, it is likely not HGPS ■ If yes, it is possibly HGPS Bokter Syndrome O Do they have a Vitamin C deficiency? If no, it is likely not Bokter Syndrome If yes, are they a sailor? . . Lupus . If no, it is likely not Bokter Syndrome If yes, it is possibly Bokter Syndrome

Your application wouldretrieve the employeerecords i.e. Employee id, name, address and ageand display this record using textbox control.Note:Don’t send me the wholeapplication. You just send me the code displaying how youconnect with Microsoft access database and afterthat you reademployee records from employee table.
write program in ASP.NET The Register control uses child controls to create a user interface (UI) for enteringuser information to register with a Web site. The UI consists of two TextBox controls, one for entering the user's name and another to enter the user's e-mail address, and a Button control to submit the information. Register also associates RequiredFieldValidator controls with the two TextBox controls to be sure that the user enters a name and an e-mail address. The Click event of the Button control is raised as the Register control's Submit event. The Register control relies on the built-in features of the child controls for its behavior. For example, Register relies on the TextBox controls for handling postback data, the Button control forthe postback event, and the RequiredFieldValidator controls for validation.
In this project you will implement a student database using JavaFX. A GUI should be used as the program's interface. This program must consist of two classes. (1) The first class should define the GUI and handle the database interactions: a. Combo box should allow the user to select one of the four database actions (Insert, Delete, Find, and Update). b. The database should be implemented as a HashMap, with the ID field as the key and a student record consisting of a name and major as the value. c. The operation should be performed when the user clicks the Process Request button. d. If the user attempts to insert a key that is already in the database an error message should be displayed using a JOptionPane message dialog box. e. If the user attempts to delete, find or update a record that is not in the database, a message should also be displayed. f. After each successful operation is completed a JOptionPane window should be…
