View 4 RepliesWhat would be the code to validate a textbox so that it can only accept positive numbers and a decimal point? If no value is entered, it automatically enters 0.
View 1 RepliesI have written a program that generates and prints 10 random integers from -10 to 10, my problem is that I am returning both negative and positive numbers, aligned right with a pad of 2, but the negative is on the right hand side of my number instead of the left. here is my code, all work but I need to align the numbers and have the correct notation of negative.

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?

View 5 RepliesI have an id called "AM01". I separated them by truncating the numbers out and increase it by 1 each time I want to add a new record. Therefore before I add the record, I would have to combine them back. I managed to truncate them and combine them back. However, the results turn out to be "AM2" instead of "AM02". So, is there a way where I could make the numbers as "02" instead of just "2"?
View 6 RepliesHow 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
View 5 RepliesI've for example this code in the TextBox1:
CreateObject(1266, 1065.21, 2546.01, 20.1, 45.0, 90.0, 360.0);
I want to get only this part of that code above: 1065.21, 2546.01, 20.1 and write this in a RichTextBox1
How to do that?

How do I have a positive number show the "+" sign before the number.
I feel that this should be easy but my searches must be too broad because I get way more info than I want and don't seem to find the easy fix.

View 2 RepliesThe problem is simple: I have a form with textboxes, and in one of those textboxes, I want users to enter either a positive or negative 2-digit number. I'm looking for an easy way to enforce this restriction, i.e. without having to parse the number and check whether its absolute value is below 100.

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.)

I'm outputting a Double that can be either (+) or negative (-). If the number is a negative the symbol (-) is included automatically, is there a way to do this for positive numbers as well?
The only (horrible) way I can do this is :
If MyNumber <= 0 then
string.Format("{0:0.00}", MyNumber)
Else
string.Format("+{0:0.00}", MyNumber)
End If
develop an application which accepts a positive integer value from the user and outputs the sum of all integers between 0 and the given integer.

View 2 RepliesI 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.
I'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.
