View 1 RepliesVB Program That Requests A Positive Integer As Input?
Nov 28, 2009i 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.)

View 7 RepliesConvert Positive And Negative Math.Sin (waveform Output Values) Into (unsigned) Byte Array?
Apr 19, 2011I'm creating an emulator for a device to simulate wave forms. My challenge is that when I try to convert the output of the following code, I can't convert the Math.Sin's double output into byte values that lend themselves to the byte array format required by an existing graphing control as listed at bottom below. I''m not sure how to handle this when the sin function creates negative values but the byte values will need to be positive and basically 'shifted up' so that anything over 127 is negative. (0 - 255) unsigned. BitConverter.GetBytes has been suggested but THIS is the result of that attempt.

Alter The .visible Property Of A Label Based On If A Variable Is Positive Or Negative?
Apr 11, 2010I want to alter the .visible property of a label based on if a variable is positive or negative (Hiding it for negative values)
But I want to do this for lots of labels so If Statements are too bulky.
I tried this:
Label1.visible = CBool(IntVariable1)
But it turns out CBool returns True for ANY value and False for Zero.I'd assumed it would be True for positive values and False for negatives.How can I do it without if statements?I considered Modulo or SquareRoots to somehow convert a negative number into zero, but didn't want to complicate things with imaginary numbers.
Write A Program To Request Positive Numbers One At A Time From The User In An Input Dialog Box
May 12, 2009I'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.

Error After Implicit Conversion Of 1 Dimensional Array Of Integer To IEnumerable Of Integer() ) ?
Apr 25, 2011I'm trying to create a linked list of an array of integers. Why is the following implicit conversion required?
When I run the code that contains that conversion, I get the following error.
As a real-time data acquisition user control data (a packet of an array of bytes) arrives every second, is converted into an integer array and inserted into a linked list.
The most recently arrived data is painted as coordinates on a grid at the right of a PictureBox using Graphics.DrawLine (pen,X1,Y1,X2,Y2).
The oldest data (arriving 120 seconds ago) will be drawn at the leftmost portion of the Picturebox.
Why a linked list rather than a list? To display 120 views of time sequence data, the draw routine the most recently inserted node to a node that points to Nothing. How do I limit the length of the linked list to 120 nodes and always ensure that the last node points to Nothing?
