Can anyone help me to break down the instructions for this assignment.Create an application that allows the user to type in a 32 bit number using the binary system, and convert that number into the decimal numbering system.For example, the user types 000000000000 0010 (where there are 30 leading 0's, 1 then 0 from left to right), and the output would be 2.The user will type a string that is 32 characters in length.A For loop 'reads' each character using the x.substring(i,1) where i is the current character we are reading and 1 means one character only,and x is the entry the user typed (use a Textbox to get the entry but Inputbox is also ok).When you start at the first character (from the right) then that value is to be * 2 ^ 0 then the second character is to be * 2 ^ 1, then the third character is * 2 ^ 2, hence:( x.substring(i,1) converted to Integer ) * 2 ^ j represents the decimal value of the current number (0 or 1) we are reading.A variable is needed to accumulate all those values.After the loop is done, display the accumulated value.To test this code on a simple version, enter a 4 digit binary number, where 0010 is decimal 2, 0110 is decimal 6, 0111 is 7, and 1000 is 8.
My understanding is the user must enter 32 digits into a textbox. The textbox should place limitations that only allow the digits "0" and "1". This error could be displayed to the user with a messagebox that then asks to reset the value orginally inputted into the textbox. My understanding is I should continue creating the formula of the position of each character where the third character is *2^2, fourth is *2^3, fifth is *2^4 and so on? I don't understand the formula and how it works.
Create a program which promps the user to enter an unlimited number of test scores. The program should show the high score and the low score. You should use a loop of your choice within this program. The program should look similar to the one below:

1. Asks the user type his/her email address into a textbox.
2. When the user clicks the "Evaluate Email Address" button, one of two message boxes pops up: "That is a valid email address!" with an "Information" icon, or "That is an invalid email address!" and on a second line, "Please retype your email address.", with an "Exclamation" icon
3. To be considered valid, the email address must -include an "@" symbol, and -it must end in either ".com", ".net", or ".org" or ".edu" (I don't know how to check a string and test if its last four characters end with any of these and make it say not valid email address. I think I might have to use a case statement)
I need to write a program that requests a high number and a low number from the user, then the program searches the array and finds all elements within the two numbers. The program is used to search for past presidents, so if I type 43 for low number and 44 for high number, the program will display:
George Walker Bush
Barack Hussein Obama
I think I have an idea of how to search up to a certain point, but not to stop at a certain point....Here is the code that I have for that particular sub procedure:

View 10 RepliesI am creating a program for which will calculate the time taken for a user to make a number keystrokes. I want to start the timer running from the beginning of the first key stroke and end on the final keystroke. Each keystroke has been linked to a label which will change colour according to whether the key has been pressed. When the keystrokes have been finished I want to save this timespan in a field in a database. To test that the timer is running I have made a messagebox which will show the time taken however it is constantly showing zero and the label for the final keystroke is remaining in the keydown colour.

Can i create a connection which will give the next registered user a user ID (a number) from the .csv?
II tried something with Sum and +1 every time an "add" button is clicked, so it would count the number of registered users but when i clear the .csv file i will have a number that ain't connected with the amount of users.
if i Ex. have twenty people registered in my .cvs file the next one will show the number 21 in a label in the "add form". Excel have the numbers from the 1 to infinity in the side if i could call the next empty line number into a label or something like that the user ID will follow the numbers of registered users.[code]....

1. Decide the headline
2. Decide the layout of the survey
3. Import pictures
4. create new pages, like a form.
And then save this survey to a file which can be opened either by itself or by using some sort of viewer program. And I want the user to be able to put in answers to questions in the survey which wont be visible when you open the file in the viewer program. Now I dont expect you to write the program for me, just give me ideas on how to solve them, where I can learn about methods to get there and so on.

View 10 RepliesYou need to design and create a program that accepts input of employee name, employee type, and the number of hours worked each week for two weeks.
You must be able to select an employee type. An employee of type Trainee makes $10 per hour. An employee of type Regular makes $15 per hour. An employee of type Manager makes $20 per hour.
The program should calculate the employee pay for the week. The employee should receive 1 times the regular pay for any hours worked over the prescribed 40 hours in a week. The program should output the following information:
-The employees name without trailing or leading spaces
-Regular hours worked
-Regular pay
-Overtime hours worked
-Overtime pay
-Total pay
The Problem that i am having right now is "Displaying " the overtime hours on my "FORM VIEW" i mean i did the math right its just when i type (lblOverHrs.Text = CDec(CDec(OvrHrsWrkWeek1.Text) + CDec(txtOvrHrsWrkWeek2.Text))
Its says the "OvrHrsWrkWeek1 and 2" are not Declared which are..im not really sure where i went wrong..
