View 3 RepliesDivision By Zero For Oledbconnection?
Feb 24, 2011I am using oledbconnection object with access database engine 64 bit to get data from Excel file. While using sqlconnection object if sql string has these statements "SET ARITHABORT OFF;SET ANSI_WARNINGS OFF;" , then division by zero exception doesn't cause any problem. But while using oledbconnection these statements cause error. My code samples are below:
Dim PbpConn As OleDbConnection = New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;" & _
"Data Source=C:BuzBeatDataPBPData.xls" & ";" & _
[Code]....
When SUM(pbA) has value "0" then it causes error and can't get data. is there a way to close the warnings and division by zero exceptions?

View 2 RepliesApproximating The Result Of A Division?
Nov 16, 2010I've got a problem approximating the result of a division that should give a sharp result:
I use this code:
pListPrice *= 100 / (100 + VATPercentage)
where VATPercentage = 20D is declared as Decimal type. pListPrice = 25.2D is declared Decimal too.
The result should be: 21.00 sharp!
Instead I get 20.99999999999999999999D
Bug On Rounding On Division And MOD Of Integers?
Feb 11, 2012I have a group of 25 labels named Label1, Label2, Label3, ... Label25 in a square of 5 per row, 5 per column and I wanted to assign the backcolor to all of them on a loop and assign a value of "True" or "False" to a matrix of 25 boolean values representing them.
But I was getting errors on the pattern created.
My approach was to use a substring containing a number copied from the label names:
Num = Val(sender.name.substring(5))
And the subindexes of the matrix:
p = (Num - 1) / 5
q = (Num - 1) Mod 5
The values for the lower corner of the matrix were rouded to 5 instead of being 4. Instead of (4,0) ,(4,1), (4,2), (4,3) (4,4) I was getting (5,0),(5,1)...(5,5)
So I solved the problem by creating two single variables "A" and "B", doing the divission and MOD operations on them, finding the floor of them and then converting to integer:
Private Sub Label1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles _
Label1.Click, Label2.Click, Label3.Click, Label4.Click, Label5.Click, _

Using Modulous And Division In An Exercise
Mar 6, 2005This exercise says :"Write a program that inputs one number consisting of five digits from the user, separates the number into its individual digits and prints the digits separated from one another by three spaces each. For example, if the user types the number 42339, the program should print
4 2 3 3 9 Use the command window for input and output. [Hint: This exercise is possible with the techniques discussed in this chapter. You will need to use both division and modulous operations go "pick off" each digit.]"
Here is what I have learned in Chapter 3:
�If/Then Statements
�Console.Write()
�Console.WriteLine()
[Code]....
This exercise I have yet to start, and don't think I will be able to do much, because I have no clue how to "Pick off" the numbers using division and modulous operators. I know what the mod operator does, but I do not know how to use it and division to do what this exercise is asking me to do.

Optimizing Division/exponential Calculation?
Apr 15, 2010I've inherited a Visual Studio/VB.Net numerical simulation project that has a likely inefficient calculation. Profiling indicates that the function is called a lot (1 million times plus) and spends about 50% of the overall calculation within this function. Here is the problematic portion
Result = (A * (E ^ C)) / (D ^ C * B) (where A-C are local double variables and D & E global double variables)
Result is then compared to a threshold which might have additional improvements as well, but I'll leave them another day

View 3 RepliesSimple Calculator Multiplication And Division?
Jan 30, 2010Simple Calculator multiplication and division Trying to make a simple calculator. My program inputs numbers and arithmetic operations thru commandbuttons. The numbers, num(n-+1), are odd and the operations, op(n), are even. The code is based on the even op string. Every time a op occurs it is stored in numop(n) to be accessed later. I have all the other operations in sequential order: "*"," "/, "+" and "-". The other similar For-Next loop are the same just interchange the two * for /, +and -. The "+" and "-" work fine in this configuration.
My problem is the multiplication and division does not occur. The numbers and operations line up. The numop(m)=g*h should yield numop(m)=num(1)*num(3). Is there some sort of code to be inserted to accomplish these multiplication and division operations?

Text Box To Data Grid Division?
Jul 9, 2011I have a text box filled with lines of names. What I would like to do is divide the text box into 3 different data grids using two different methods (one button for each)Method one: divide the test box by line number into 3 different data grids e.g. lines 1, 4, 7, & 10 go to datagrid1, lines 2, 5, 8 & 11 go to datagrid2 & lines 3, 6, 9 & 12 go to datagrid3.Method two: divides the group into 3 groups based on top 33% go to datagrid1, middle 33% go to datagrid2 and the the remaining 34% (bottom) go to datagrid3.The number of lines in the text box should never exceed 50 but best left not limited just in case.

Dec 23, 2009If you create new projects in C# and VB.NET, then go directly in the Immediate Window and type this:

C# will return 0, while VB.NET will return 0.567.To get the same result in C#, you need to type
? 567 / 1000.0
Why is there this difference? Why does C# require the explicit decimal point after 1000?
