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.)

Regex 4 Digits A Hyphen And 4 Digits?
Jul 2, 2010I'm trying to match a string to see if it matches exactly this:####-####, it has to be 4 digits followed by a hyphen followed by 4 more digits. Right now I have this pattern: "d{4}-d{4}" but it's allowing 5 digits in either (or both) instead of strictly 4 per group. Here's an example of what it should allow:
1999-2000
2003-2007
2009-2010
and here's what my pattern is allowing but should not be allowing:
20081-2009
2009-20101
12345-12345
12345-1234-1234

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.

VS 2008 - Calculate Factorial From Number And Display In Textbox
Sep 14, 2009So I need to get a button to take the number that a user enters into a textbox, calculate the factorial from that number, and display it in another textbox. I can't seem to get this to come out right.
Here's some of the code I've been playing with.
Private Sub btnCalculate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalculate.Click
Function Factorial(ByVal txtFactorial As Decimal) As Decimal
If txtFactorial <= 1 Then
MessageBox.Show("Enter a number greater than 1")
Else
txtAnswer = Factorial(txtfactorial - 1)
End If
End Function
Now I have to just work out the code part. Can a function be under a button? I'm getting an error about that. I'm also getting an error about the txtAnswer=Factorial(txtfactorial-1) part of the code.

VS 2008 String.Format 2 Digits Always?
May 28, 2009For some reason I can't figure this out. Here's my code. colorTextbox.Text =Format(Hex(ColorBox.Color.G), "00")What I want it to do is format the Green Hex number to be "00" instead of just "0" when the color is something like blackhis has proven to be very stressful and this Format command makes no sense to me anymore (worked differently in 2005).For one, whatever I put in the quotes ("00") is what comes out in the text box. Butaccording to the command parameters, "00" should be the format, not the actual text! So then I tried any string format I could think of (## etc.) along with switching the order and I STILL can't figure this out.

VS 2005 Display Each Number Twice And Then Move On To Next Number
May 4, 2010I am trying to run a nested loop; it should call a result from a MDB database. Which it does, when I run the single loop it goes thru all of the entries. But when I try to get a number to display twice it stops on the second entry. Having it display the number twice is just a test to make sure it does work, I am going to modify it after I can prove the loop works. The count on the Message Box is correct, but the number displayed is wrong?I want it to display each number twice and then move on to the next number. [code]
