Is it the case or not? A form's Text property gets its name assigned to it when it is first created.
Create the design for determining if a point is inside, on, or outside of the rectangle. Drawing out the rectangle and labeling the coordinates of all points will help you to visualize the problem. Once the design has been completed, write a program that prompts the user for the x and y coordinates for the lower left hand corner of a rectangle as well as the height and the width of the rectangle. After that, you will need to get the coordinates for the point from the user as well. Once all inputs have been entered by the user, determine if the point is inside the rectangle, on the rectangle, or outside the rectangle. If the point is inside the rectangle, print "inside the rectangle". If the point is on the rectangle, print "on the rectangle". If the point is outside of the rectangle, print "outside the rectangle". Example output: Enter the x coordinate of the lower left hand corner of the rectangle: 1 Enter the y coordinate of the lower left hand corner of the rectangle: 1 Enter the…

Need help with this. I attached how it should look Create an event listener for the click event occurring with the submitButton that runs an anonymous function. Within the anonymous function add the following if else structure: If the pwd field fails the pattern match, display the validation message “Your password must be at least 8 characters with at least one letter and one number”. Else if the value of the pwd field does not equal the value of the pwd2 display the validation message “Your passwords must match”. Otherwise, set the validation message to an empty text string. Save your changes to the file and then open project06-01 in your web browser. Verify that you cannot submit the form if your password is less than eight characters long and does not include at least one number and one letter. Verify that you cannot submit the form if the two passwords do not match.
Is this correct, or is it incorrect? When a form is created for the first time, its Text attribute has the same value as the form's name. This is carried out as part of the startup procedure
Is that so? The default value of the text field is the form's name.
