C# - Format Double As String With Positive / Negative Symbol?

Aug 25, 2011

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

Alter The .visible Property Of A Label Based On If A Variable Is Positive Or Negative?

Apr 11, 2010

I 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.

Convert Positive And Negative Math.Sin (waveform Output Values) Into (unsigned) Byte Array?

Apr 19, 2011

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.

is there any way to get a numberupdown text to show the value "+" so if the value is a positive number then it adds the plus sign in front of the digits.

example:

2.00 would become +2.00
3.25 would be +3.25

as when its negative its

-2.00
-3.25

It already adds the negative value when its negative of course.

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.)

Write A Program To Request Positive Numbers One At A Time From The User In An Input Dialog Box

May 12, 2009

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.

Why Does A Negative SByte Number Have 16 Bits

Jul 11, 2011

I asked a question earlier about comparing numbers using the "And" comparison operator in If Statements and now I have been toying around with getting my head wrapped around bitwise operators. So I have written a very basic code that will allow me to see the conversion of any decimal number in binary format.[code]Notice here that I am using SByte as the paramerter - which should only contain 8 bits right? However, the message box that appears has 16 bits assigned to negative numbers.

VS 2008 - Windows 7 API - Number Isn't Even Negative Anymore

Jul 11, 2010

My problem is with the following API.

Private Declare Function GetKeyState Lib "user32" (ByVal keyCode As Integer) As Integer In Windows XP, I could simply use the API like this: If GetKeyState(Keys.Left) < 0 Then 'Move Left If the key was pressed, it was a certain number below 0, the number itself alternated each time you pressed the key but it was always below 0.

My problem is that in Windows 7, when you press the Left key, the number isn't the same, in fact the number isn't even negative anymore. This problem tricked me at first into thinking the API didn't even work as when I ran the .exe of course my code did nothing since GetKeyState never returned a number below 0. I tested the value itself though and found that it never goes negative, the number for the key just decreases a little.

The weird thing is, while the .exe from the Debug folder proved my point that the GetKeyState number was different and thus the program didn't work, running the .exe from the Release folder actually worked, the controls were fine and the API returned numbers less than 0 for GetKeyState. But the .exe from the release folder was built with my old XP computer, as soon as I made a new build with my windows 7 computer the API stopped working again.

Why did Windows 7 change the number returned for when the key is down, is there a way to change it back without having to include some large package with my program? Why did the build from my XP computer work at first? Also it was only the one from the release folder, not the debug one, even though they were both from the XP computer.

I tested some more on windows 7 and found that every time I run the program, the number returned by GetKeyState is completely different. When the key is down the number is 1,000,000 units higher than up, but other than that the number is random each program start.

.net - Formatting A Negative TimeSpan?

Jul 11, 2010

I'm doing some math with the Timespans in .Net, and occasionally the sum results in a negative Timespan. When I display the result I am having trouble formatting it to include the negative indicator.

Dim ts as New Timespan(-10,0,0)
ts.ToString()

This will display "-10:00:00", which is good but I don't want to show the seconds so tried this.

ts.ToString("hh:mm")

This returns "10:00" and has dropped the "-" from the front which is the crux of the issue. My current solution is this:

If(ts < TimeSpan.Zero, "-", "") & ts.ToString("hh:mm")

but I was hoping to accomplish the same by using only the format string.
