Getting Answers Into Decimal And Calculating
Feb 10, 2009
I'm trying to get the answer "dblcost" to go into 2 decimal spots. Sometimes it does, sometimes it doesn't.Also, I have to create something that continually adds each transaction to lblfinalcost. Mine seems to be a little buggy.Right not I have strfinalcost = strginalcost + dblcost. Another question i have is how do I make a number default into the textbox? I want it to say 1, but be able for the user to delete it and then replace it with their own number.[code]

if you are a constant answerer here on msdn, and do not have a unique signature, or no signature at all, please take a little time to create one... eason ..when quoting a post of a member, if no signature available, then it would have to be followed w/ "quoted from so and so's post", this so so said this, etc.

When Score exam is clicked, the answers from the keys file is read using ReadLine method 6 times to fill the Answer Array. then the users' answers and the answers from the keys will be paired up by calling "Compare_Answers" function in the RMV Global Module. and calculate the score and it will show on the main form.

Sum: 5 = 2 + 3
Difference: -1 = 2 - 3

The goal in this assignment was to create a Magic 8 Ball that would display answers via array.Here's what I got down so far, now I apologize once again, I forgot most of the stuff so I don't even know if it is REMOTELY close to what it's suppose to be
Public Class Form1
Dim ArrayRes(7) As String
Private Sub btnASK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnASK.Click

I'd like to create one as I am an affiliate marketer who wants to reach customers based on key words. I don't regard this as spamming since I'm not randomly sending out links its based on key words like I said. Y!A might regard this as spamming anyways but so what. In Yahoo Answers you click the question you want to answer, type in the answer, it takes you to a preview screen, and then you click submit. I suppose the script/program could involve automating this task.
Its not that I need everything to be done when I'm away from the computer, I don't mind working the program at all each time I send a mass amount of messages. Someone created a program a while back that was *supposed* to send bulk messages as they stated in the description but as it turned out this was not an option you could only comment on resolved questions. When I did send mass comments to questions which related to my key words, I clicked the link to confirm my comments went through and they did not! This program was a waste of my time and energy but that's life.

I'm having trouble with the Try...Catch code. I'm trying to make the textboxes only accept letters A, B, C, or D as answers from the user. I'm also having trouble matching the two arrays. I wanted it to be like if textbox1 is A then it is correct but in a loop. Please take a look at my code.

I am working on a multiple choice quiz, admin screen, student login screen where they choose their level of difficulty. I have been able to start the quiz, have the questions and answers filled, user answers question, check if correct or not, if correct then the score is incremented.I am able to set up a variable for 'level' and want to write some code so that whatever is selected then that table / questions will be selected and displayed to the user.
The way I'm thinking at the moment seems very long winded. I think I'll have to write an IF ELSE statement/case statement for each of the 'navigaterecords' and the sql statment for beginners, intermediate and advanced.Assume there is a variable 'LEVEL' - have not actually done this yet. Where the code refers to 'advanced' is where I have been trying it out to select questions from the advanced table.

trying to make a Multiple Choice quiz, with 20 questions
-4 RadioButtons
-2 Label (Reading the Questions) and 1, keeping a score count
Do I wanna make some arrays like Questions(20) and Answers(20)
Dim ScoreCount as Integer
So I want it to be a little screen, and once you click a Radiobutton to choose answer, it will change the label to Question(2) so forth.. but I am unsure how to do this. I am fairly new to vb, im doing this to learn.How do I make it so everytime you click a radiobutton wether it's right or wrong, the next question and possible answers all change??

My user requests to change the . on the numpad to a when entering text in a multiline textbox.So I was thinking about the KeyDown event.To determine if the numpad . was pressed I can do something like this [code]But now how do I change the returned charachter as a , ? All e.Key... properties are ReadOnly. The KeyPress events let me change this by providing e.KeyChar, but in that event I can't check for the numpad .

How would I go about rounding up decimal numbers to the nearest 2 decimal places? For example $7.0000032 would be $7.01 In theory, VB would make it $7.00 but if it is > $7.00, I want it to reflect that to the nearest penny... so $3.0000001 would be $3.01

I have a form with 10 math questions. Beside each question there will appear a check mark if it is right and a X if its wrong. I also have a label that will display a score in percentage. If 2 are right then it will display 20%. If they are all right then it displays 100%. My problem is ...how can I code the event. I thought of case select, but that would mean 100 cases to make it work.( If check1 and check2 are visible then display 20%, but if its check1 and check 7? Thats alot) What I want ot know if there is an easier or shoter way to ontain the same result. I am working with Visual Basic 2008.

i am creating a quiz which would be 20 questions for software design students and may use alot of code.my first problem is the score for the test, i know a friend of mine can add up the score but he cant move onto the next thread until you have got the question correct which is sort of cheating, i want to know how you create a variable and make that variable stay in all the forms and add up the score of correct and incorrect answers and come up with a final score for the user in the end.

Maybe this is just a really basic question that everyone knows the answer to, and is why I couldn't find the answer. What I want to do is pretty simple. I want to declare a custom type that's just like a Single, except when you access the value, you get the value rounded to the second or third decimal place. Something like this:
Dim MyNumer as TwoDecimalNumber
MyNumer = 1.124
Msgbox(MyNumber) 'This would pop up a box showing "1.12"

Problem: Using the sub routing below, when adding a value to another value the results eventually change from 2-decimal places to multiple decimal places.Basically, the amount stored should always only be 2 decimal places, because the values passed in are always 2 decimal places. Output from calling the sub routine multiple times.
Running total = 329430.75
New Withheld Amount = 710.79
Running total = 330141.54
[code]....
As a workaround, I have a new routine that uses a custom round function to properly store only 2 decimal places - as the VB round function does not perform the type of rounding desired.I understand that we are removing the value from the dictionary and adding it back..
