I need to display a grade based on the number of points entered. store the min and grade in a 2d array here's my code that I have currently:
Dim strGrade(,) As String = {{"0", "F"},
{"300", "D"},
{"350", "C"},
[code]....
I have a homework assignment to code an application that allows the Prof to display a grade based on the numnber of points he enter. The grading scale is : 0-299 -F; 300-349- D; 350-399- C; 400-449- B; 450-500- A. We are to store the minimum points in a 5 element one dimensional Integer array name intPonts and store the grades in a 5 element one dimensional String array name strGrades. The arrays should be parallel arrays. The procedure should search the intPoints array for the number of points entered by the user and then display the corresponding grade from the strGrades array.
I have stored the minimum points and grades in a one dimensional integer and string array respectively. I have coded the program, and when I put in random points, it gives me the letter grade. For example, if I put in 376 it will display a "C"; if I put in 200, it will display an "F". However, if I put in anything over 449, it will NOT display an "A", it just leaves the lbl blank. I am stumped on how to get the code to read pass 449 points.
here is my code:
' Name: Carver Project
' Purpose: Displays a grade based on the number of points the user enters

Well I have a list of things I want to search based on multiple points of data...for example Resolution, 3D capable, touchscreen capable....etc....What is the best way for display someone can think of & filtering results by capability, I have none of it typed out, etc...like list of objects & capabilities, etc... alreat...so it can be made any way that is thought to be good(with speed as well) for many different listings...say 1,000 of them & it filters pretty much instantly....reading capabilities & such & the list itself is easy but how can I make a filter(unchecking something brings back things, checking something takes away only since well your adding capabilities to filter selection....I have pictures that can go with items too as well as a name & more information could be given directly with the method or clicking on the picture/item.
View 13 RepliesI have a UI that uses datagridviews / bindingsource / datatables of typed dataset for data entry. The dataset itself is serialized to a varbinary(max) in SQL. (i.e. no tableadapter, backend schema).I would like to limit the number of rows the user can enter into some of the grids (the data is used to fill PDF forms and I don't want them entering more rows than the forms can accomodate.).I have subclassed the datagridview, added a rowlimit property and tried to manipulate the AllUsertoAddRows property
Imports System.Windows.Forms
Public Class dgv
Inherits System.Windows.Forms.DataGridView[code]......
The behavior I see is that the messagebox comes up after leaving the max row even when the user is trying to leave the grid. I can lose the messagebox and deal with notification some other way but I thought someone else may have come up with something a little more sophisticated to handle simply causing attempting to add to many records to navigate out of the grid to the next UI control.
Is there any way to have my code display the min and max grade without having to re due most of it?
View 2 RepliesI need someone with patience and can go through a solution with me from the Clearly Visual Basic book. I'm good with computers and can usually learn things relatively fast on my own time and in my own way, but I'm going to school for computer programming and, with certain things, I learn better with things explained to me rather than reading from a book. If someone has the time to go over this solution I'm doing and explain it to me in a way I'd have a better chance of understanding, I'd be truly grateful. I need a tutor, for lack of a better word. The lab I'm doing is from the Clearly Visual Basic book and the instructions are:
Code an application that displays a letter grade based on the averages of three test scores. Code the application using a function to determine and return the letter grade. If the average is at least 90, the grade is A. If the average is at least 80 but less than 90, the grade is B. If the average is at least 70 but less than 80 the grade is C. If the average is at least 60 but less than 70, the grade is D. If the average is below 60, the grade is F.

View 4 RepliesI have previously asked a questions regarding DataGridView control:[URL].. now I'm trying to make the first column to include an autosuggestion. ie. when a user types an ID(say, "12") then all the records that starts with it(ie. "12*") will be displayed as suggestion.
And upon clicking an ID, the corresponding product_name will be displayed on the next column. I think, I could do this using Validating() event of DataGridView.
the disply color buttons click even procedure shold display the color of the item whose item number is entered. all item numbers contail eactly five characters(12b12). my problem is i can not get it to disply a color in the lblcolor control. it displays the item number.

I have a need to verify SSN's that are entered based on a reserved range (these are used for advertising and will never become valid). The input is from a masked text box formatted as 000-00-0000. I may be wrong, but I figured the most logical method would be to remove the hyphens and convert the string to an integer, then compare the starting point and end point of the range.
'Valid SSNs
'Currently, a valid SSN cannot have an area number between 734 and 749, or above 772, the highest area number which the Social Security Administration has allocated. This should not be confused with Tax Identification Numbers which include additional area numbers.

I'm looking to write a very simple program which asks a user to enter a number between 20 and 50. The program would display the letter 'I' in a textbox to correspond to the number the user entered (i.e. if the user entered 34 then 34 I's would be displayed. I'm not entirely sure of what commands would make this happen.

I'm trying to alter the existing number formatting in my company's application to make it more readable for international users. This is a stock trading application, so most stock prices come in with numbers precise to 2 decimal points, like so-> 17.23 We could also get ticks in that have precision out to 4 decimal points, so a penny stock might be 0.0341. The original string format that we were using for stocks was "#,##0.00##" Which would give us the format we wanted (essentially trimming '0's). The problem here is the ',' and '.' are forced onto the user, where in many other countries the thousands separator is '.' and the decimal point is ','. Boss man doesn't want to use "N4" for all numbers, even though this would resolve the globalization issue. Is it possible to have a globalized custom string format?
Other options besides writing some middle man code to internationalize numbers formatted the original way or another string.format method?
