VB Program That Requests A Positive Integer As Input?
Nov 28, 2009
i did this much but something doesn't seem right...the question is A Visual Basic program that requests a positive integer as input, and carries out the following steps:If the number is even, divide it by 2.Otherwise, multiply the number by 3, and add 1 to the result. Repeat this process with the resulting number, and continue repeating until the number 1 is reached.After the number 1 is reached, displayed how many iterations were required to reach the number 1. (Hint: a number is even if number Mod 2 = 0.)
Private Sub btn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn.Click
Dim num, multiply, divide As Double
I'm currently in VB class at my highschool and we just got chapter 6.1 to read on this online textbook that we follow. Anyway, we are doing loops now and the problem reads "Write a program to request positive numbers one at a time from the user in an input dialog box. The user should be instructed to enter -1 after all the positive numbers have been supplied. At that time, the program should display the sum of the numbers." So far I know this much
[Code]...
Now I know this isn't right But I can't find out how I'd pull out the numbers the user entered to get the sum of them and not include -1 because as it stands, when I hit ENTER with -1 the label just shows -1.
I have temp2 value -52340.0 and hslColor.Luminosity is 240.0 When Dim temp1 As Double = (hslColor.Luminosity - temp2). It shoud give -ve number but I am getting always positive number. results should nbe -52100, but I am getting +52100. How to handle this?
(Write a program that requests a word containing the two letters r and n as input and determines which of the two letters appears first. If the word does not contain both of the letters, the program should so advise the user.)I got the program to work but he said its wrong because we need to have it looping and if one of the letters is missing you also have to say which one is missing.I have some of the pseudo code but I don't know how to make it work.If Index of("R") = 0 or index of ("N") = 0 Find out which is missing and display message.Else Find larger and display message.
Is it possible to make a program intercept and stop certain write requests? I need it to stop viruses from tampering with an antivirus database. If you can, how do you do it? If not, is there another way to stop viruses from changing the database?
Write a program that requests a name fomr the user and insert the name into the list in its proper location, if the name is already in the list, the name should not be inserted. --do not use any arrays or LINQ use only streamreader/streamwriter.What i've got is this...it will add the name but not in the "proper location". if i could use an array i'd just reorder the array and then write to file, but...

I'm trying to compare something the user sends to a listview(first column) to see if it can find a match using [code] and if it equals true the program requests a password if its false it returns the noturous "failed to login"
Is there a easy way to input a string or integer into another exe's textbox for example, if i wanted to write into the textbox on the windows calculator '3'.
I'm looking for a way to calculate an average from a input integer within a loop. When the user enters something like -90, the average will be calculated using the previously input numbers.
I have a web page with 5 checkboxes and 2 textboxes per checkbox. When the user checks one or more checkboxes the corresponding textboxes become enalbed for UI. I need to insure that the input for the textboxes is an integer-that I will do with a validators. There is a gridView on the same page. When the user checks one or more checkboxes the 2 columns of the gridView rows become active for input through enabled textboxes.
There are 4 columns in the grid. The minimum number of rows enabled are 2 and the maximum are 26. The UI for the grid's textbox input is numbers. Those numbers have to be equal to or less than the total. How do I validate UI of numbers(integers) into the grid's dynamically generated textboxes and then add the total and compare it to the alloted total? I prefer to do this with the code behind - using VB.NET - rather than with ASP.NET or absolutely not javascript.
I was wondering how to make my Text Editor handle "Set As Default Program" requests, and have files saved default-ly open with it. For example creating my own file type.I don't know if this is possible in VB.net
This function doesn't work if I change the input argument 'pdu' from a string to an int.Would someone please help me figure out what to do here so that the checksum does not add the ascii value of the int argument but rather the actual integer value?I took out a few lines of the actual function but it adds the input argument to a packet sent out via TCP protocol.This function shows the integer value just fine in the string that gets encoded as a byte array. the checksum is wrong.!
''Public Function buildpacket(pdu As Integer) is what I want. Public Function buildpacket(pdu As String) Dim packet As String
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:

Private Sub btnDisplayRqst_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDisplayRqst.Click Dim sr As IO.StreamReader = IO.File.OpenText("PRESIDENTS.TXT")
i use visual basic 6 i already try making a button to play sounds. by clicking the button and the sound will out. so that i want to know were could i start, when you input words in textbox the program will speak what you have type in the textbox. _
I have a procedure at the end of my console application that ask the user to either hit enter to end the program, or type s to perform another search. The issue I'm having is no matter what the user types in the program end. What I would like to happen is if the user types s, then the program starts over and lets the user perform another search. The program is procedural and I need to find a way to start back off at the top of the program which ask the user to type a name to search.
The project I'm working on is a Multichoice RadioButton quiz with answers and percentintegers. At the end there is a MsgBox that gives the number of answers counted 'correct'and the percent 'correct'. Also after you press the confirm button on that MsgBox it emails the results to the built in information given on the SMTP information. What I am trying to do now is show the input typed into the textbox on FormA in the MsgBox at the very end.
Is there a built-in function in .NET (VB) to convert a negative number into a positive, and vice-versa?I usually end up just using:NegNum = PosNu - (PosNum * 2)PosNum = NegNum- (NegNum * 2)
For the life of me, I cant seem to do this. In the textbox_textchanged method, I want Button to disable in textbox has anything else besides whole positive integers.If text box has positive integers, i want button1 to enable.
