VS 2010 Set The Maximum Number Of Digits Before The Decimal?
Sep 2, 2010Im wanting to use a textbox for the entry of Decimal figures (currency). Is there any way I can have it so if a user does not put a decimal figure (ie 15 instead of 15.00) it will put it on.
I tried a masked textbox, but that means i have to set the maximum number of digits before the decimal too which is no good.

VS 2008 : Serial Port And Index Out Of Range?
Aug 13, 2011the program works fine but there is the possibility of a problem because this error message did pop up.I'm gathering my data bytes in an array --
dim rcvdata(19) as byte
serialport.read (rcvdata,0,20)
serialport.close
(Then decipher the array).But Should I go further with this? Could the error be related to my serialport.read?What if there were NOT 20 bytes read into the array?I think this may be it? I should poll the array for 20 bytes before proceeding?Yes? -- (It's a given and that's standard procedure).No? -- Don't worry, they're going to be there (the read will try again if it has to?) It won't proceed without the 20 bytes?
Format Decimal Number (Comma As Fraction Separator With Two Digits)
May 22, 2012Is there a format string to format a decimal to 000000000,00. So first 9 digits, right padded with zeros if needed; a comma as fraction separator and two fraction digits.
0 => 00000000,00
12 => 00000012,00
987456,456 => 000987456,46
So something like myDecimal.ToString("D9") together with .ToString("F2").
Project Eulers 16 In Visual Basic. Sum Of Digits In The Number 2^1000?
May 29, 2009Project Euler's problem 16:2^(15) = 32768 and the sum of its digits is 3 + 2 + 7 + 6 + 8 = 26.
What is the sum of the digits of the number 2^(1000)?I have been trying to do this problem for a few days now and i just can't figure out how to get vb.net 2008 to recognize anywhere near that large a number. I have seen in other posts that some software like java has the integer type BigNumber or BigInteger but i cant find anything like that in visual basic. I'm running into this problem a lot using Visual Basic. I also can't seem to find any of the standard upper level math features in visual basic such as factorials and a few others that i can't remember but couldn't find under the math feature. any suggestions? (Sorry let me rephrase, any suggestions on how to do this stuff without switching to a different programming language.)

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?
Sep 29, 2009is 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.
Generating Random Number Within Specified Range
Apr 7, 2009I'm using VB.NET 2008 Express Edition and I'm trying to create a simple program that will roll a number of dice I choose. It does this by generating a random number within a specified range (I'm rolling 3-sided dice in this case so I'm generating numbers between 1 and 3) and adding each number to a textbox to create a total of all the dice rolled so far.
This is my
Private Sub butRoll_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles butRoll.Click
Dim RandNum, i As Integer
Dim RandomClass As New Random()
'if at least one dice is rolled
If txtD3.Text > 0 Then
[Code] ......
Now the problem I am having is that although my random number generator is generating the right numbers (confirmed by checking the txtLastRoll textbox), when I add it to txtTotal, it seems to be getting another number from somewhere and adding that to my random number then adding it to the total and I have no idea how this is possible! txtTotal always starts as 0 but txt1 is not showing that. Normally I would just set txtTotal to 0 there but if I do that, I won't be able to add the numbers together. I've tried finding a pattern in the mystery numbers appearing in txtTotal but they just seem to be random.

View 5 RepliesRandom Number Generate (within Range)?
Nov 30, 2009The object of this project is to write a computer program that will allow the computer to guess a number that you have selected. The computer will make a guess and you, the player, will tell the computer if it guessed too high, too low, or that it guessed the number.The program will also allow the player to start a new game or to exit the program. PROJECT INSTRUCTIONS:
1. Create a form with a labeled box to display the computers guess.
2. Create a new game and an exit button.
3. Create objects to indicate if the guess was too high, too low, or right on target.
4. Create program code to respond to the player�s indication by selecting and displaying a new computer guess.
5. When the computer guesses the player�s number, reset the so that a new game may begin.
I have done all as above and so far my code looks like so
Public Class Form1
Dim Guess As New Random()
Dim HGuess As Integer, LGuess As Integer, current As Integer
[code]....
The problem i ran into is that if for example a user has a number 24, when the program makes an initial guess of 50,i want to be able to click low, and the program should generate a lower number say example 22. If i then click higher as my actual number uis 24, the program should not shoot higher than a number it has previously guess incorrect (in this case 50) it should guess anywhere from 22 - 49 and in turn limit the range of the next consecutive guesses it till hits the right number. My code right is guessing as it shuold but not within the limited ranges.
