I need help in VBA coding assignment

This week we looked at wireless network security and the issues related to mobile devices. In today’s locked down world with almost everyone working remotely, new challenges that require encryption and cryptography have arisen. And almost everyone is using wireless networks and / or mobile devices.

Today’s Global Economy is very top-down driven with the government making all the decisions and regulations as it relates to doing business globally.  What are some advantages and disadvantages to this approach?  Is there another approach that might work better?

Please make your initial post and two response posts substantive. A substantive post will do at least two of the following:

Ask an interesting, thoughtful question pertaining to the topic

Answer a question (in detail) posted by another student or the instructor

Provide extensive additional information on the topic

Explain, define, or analyze the topic in detail

Share an applicable personal experience

Provide an outside source (for example, an article from the UC Library) that applies to the topic, along with additional information about the topic or the source (please cite properly in APA)

Make an argument concerning the topic.

At least one scholarly source should be used in the initial discussion thread. Be sure to use information from your readings and other sources from the UC Library. Use proper citations and references in your post.

This week’s journal article was focused on the Complexity of Information Systems Research in the Digital World.  Complexity is increasing as new technologies are emerging every day.  This complexity impacts human experiences.  Organizations are turning to digitally enabled solutions to assist with the emergence of digitalization. 

Please review the article and define the various technologies that are emerging as noted in the article.  Note how these emerging technologies are impacting organizations and what organizations can to do to reduce the burden of digitalization.

 The paper should meet the following requirements:

• 3-5 pages in length (not including title page or references)
• APA guidelines must be followed.  The paper must include a cover page, an introduction, a body with fully developed content, and a conclusion.
• A minimum of five peer-reviewed journal articles.

 Mrs Parker owns and operates a meat shop that processes and packages parcels of minced meat that is being sold to schools in the US. Her scales are all calibrated to perform measurement in pounds, however when the parcels are packaged, they need to be labelled in ounces. Mrs Parker has established that 1 pound is equivalent to 16 ounces. In each production cycle, 250 packs of meat are processed and the weight in pounds varies for each package. Mrs Parker is also interested in knowing the total costs, the total revenue and the total profit of each production run, given that the costs to produce and package an ounce of meat is US $0.25 and that the selling price of an ounce of meat is US $0.55. Because you are a budding Software Engineer, she has sought your assistance in creating a software solution that can be used within the business establishment. 

Required: A. Specifically identify the type of control structure which is needed to process the meat in each production run and provide a reason for your choice (4 marks) 

B. Your solution needs to represent the meat packages which are to be processed, how would you represent this appropriately in your program and what has guided your choice?  (4 marks) 

C. Construct a C# program that will solve Mrs Parker’s dilemma by making use of the choices made above. 

i. Implementation of the control structure to process the meat (2 marks) 

ii. Implementation of the meat packages to be processed (2 marks) 

iii. Calculation of costs, revenues, and profits (6 marks) 

iv. Appropriate program outputs displayed to the user 

Implement a hexadecimal calculator for iOS. Requirements: 

• The calculator should support 4 basic arithmetic operations: + – * and / 

• The calculator will operate on hexadecimal numbers, not decimal numbers 

• The calculator only needs to operate on unsigned integers (i.e. UInt). You do not need to consider negative numbers or fractions.

 • The calculator should support the 16-digit hexadecimal numbers (i.e. The range of the numbers is from 0 to FFFF FFFF FFFF FFFF). Prevent the user from entering a number that is greater than FFFF FFFF FFFF FFFF. 

• The calculator should handle overflow and underflow gracefully. The app must not crash. 

• The calculator should handle division-by-zero error gracefully. The app must not crash. 

• The calculator should be able to support most of the devices and orientations. If it does not support the old devices earlier than iPhone 6, it is okay. 

Hint:

 • To convert a string to a hex number, use “radix: 16” as an argument. 

For example: var s:String? 

s = “1A” 

var intHex:UInt = 0 

intHex = UInt(s!, radix: 16)! 

print(intHex) 

// shows 26

 intHex = 90

 s = String(intHex, radix: 16).uppercased()

 print(s!)

 // shows 5A

• It is recommended that you use a UI label instead of a text field, so that the user will not type directly by using a keyboard. You will need to provide a button for each digit. 

• Strings may be concatenated by using + operator. 

E.g. var s1 = “1234” var s2 = “5” 

print(s1 + s2)

 // shows 12345 

You may want to do string concatenation in the action of each digit button.

 • To prevent the user from entering a number exceeding the size of 16 digits, you may verify the length of the string associated with the UI label. 

• To handle overflow and underflow, use &+, &-, and &* instead of +, -, and *. 

• To support different devices and orientations, use stack view, scroll view, or both. 

• Design your algorithm first! 

Think about the status of the calculator: when to take the first operand, when to take the second operand, when to append digits to the current number, and when to refresh the current number, etc. The functionality of your hex calculator worth 60% of the credit, while the appearance of the user interface worth 40%. When you submit the assignment, please compress the entire project folder into a single zip file, and upload it to D2L. In addition, please provide 4 to 5 screenshots of your app in different devices and orientations. If your app doesn’t work on every device/orientation, please specify why.
