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, 2009

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.

VS 2010 Set The Maximum Number Of Digits Before The Decimal?

Sep 2, 2010

Im 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.

Format Decimal Number (Comma As Fraction Separator With Two Digits)

May 22, 2012

Is 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, 2009

Project 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.)

Executing A Sql Command - Number Of Values Provided Must Be Equal To The Number Of Placeholders In Query?

Aug 11, 2010

I have a problem with a sql query. Through the query I am trying to search database for any occurrences of string (can be anything) in a column using the SQL LIKE command. The problem is that it works fine for most of the strings say john, jim, ji"m , but does not work when i include the following characters which are ( ' , { , } , and a single quotation mark). MYSQL query takes care of these special cases by putting them in [] block whenever user enters them .But i am getting the following error when i go to query the database using the GetSelectCommand() in VB.NET

Exception Details: System.ApplicationException: Number of values provided must be equal to the number of placeholders in query.I have checked the query over and over again .. but its fine .My database server is Sql Server 2008.So my application throws the exception in this command:

Using reader As MustDisposeDataReader = _
pmSystem.DatabaseManager.GetSelectCommand(selectStatementBuilder.ToString(), New Object() {})

Where MustDisposeDataReader is an instance of a class in an internally developed library, which inherits from System.Object. pmSystem is an instance of the class PlanManagerSystem which implements the commandlayer. GetSelectCommand() takes the select command

Regex 4 Digits A Hyphen And 4 Digits?

Jul 2, 2010

I'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

Insert Letter "N" And Have Followed By 4 Digits Is Entered By The User In To The Text Box?

Nov 8, 2011

NOTE: I tried using concat() method, join method and even tried to insert just text(which turned out editable) but none of them worked as I wanted. I was thinking if substring method will work but I only have basic idea of how substring works. I want the letter "N" to be inserted into the text box when form loads and when the user enters 4digits(OrderNo2.text) which should be joined so that it can be saved together when I clicked on save button.
