Division By Zero For Oledbconnection?
Feb 24, 2011
I 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?

I'm converting a VB6 + ADODB app to VB.NET 2010 and targeting both x86 and x64 I understand that ADO is available in both 32 and 64 bits and that .NET supports it.The VB6 code uses ADODB and ADOX to work with OleDb and Odbc data sources. It also uses the Jet and Replication Objects 2.6 library to compact and copy Access database files (if the uderlying database it's using is Access)I'm wondering if I should consider using OleDbConnection/OdbcConnection in the .NET version of the software or stick with ADO.I've looked at OleDbConnection, OdbcConnection and SqlConnection and can see that porting the old code over would be time consuming and risky.

HI!, i'm using VB.NET 2005. I want to use OleDbConnection in my .net application but it is not showing in the 'Data' section of the 'toolbox'. is there any way to import it to the toolbox.
NOTE: (Also OleDbDataAdapter, SqlConnection,SqlDataAdapter, etc are missing in toolbox)

What's the difference between / and for division in vb.net? My code gives very different answers depending on which I use. I've seen both before, but never knew the difference.

Dim con As New OleDb.OleDbConnection
Public outputs As New DataSet
sub main()
sqlquery("SELECT * FROM Students", "mark")
[code]....
Here is an image of my table data and design I am trying to read some values from a database using the oledb dataset however when I run the sql command and get down to outputting the value I am greeted with the following error: "IndexOutOfRangeException: There is no row at position 0.". Yet when I run the very same sql command in access I get back the data I wanted.When I am running the above code, no errors are produced until I get down to the last writeline where I want to output my data.

I'm developing application in VB.NET 2008.I'm reading data from Excel through OledbConnection. Here data are reading sometimes perfectly but sometimes it is missing to read some data.
Example :In Excel ,I have 79 columns in excel and 4 rows , first 3 rows are headers so after import i'll delete that rows and actual data starts from 4, so here i have only one row.After Reading through oledb, that dataset's datatable has only first 3 rows( first row became header and 2 & 3 row only in datatable, its ignoring 4th row)

Assuming that an x64 version of ADOX is not available, how do I rename a Microsoft Access table from an x64 WinForms app using an OleDbConnection with the Microsoft.ACE.OLEDB.12.0 provider?

Like we can retreive all the records from a table using this method:
While (Not rst.EOF)
....
End While
How to retrieve all the records when using OleDbConnection?

I'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

I 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, _

Deviding an int by zero, will throw an exception, but a float won't - at least in Java. Why a float have an additional NaN info, while int haven't?

In the following linq query I have a division by zero exception wich I can't seem to code around. It occurs when the Sum of fldDevider returns 0.[code]...
How can I Make sure the ValuePerMonth field is 0 when the Group.Sum(Function(dr) CDec(dr.Field(Of String)(fldDevider))) function returns a 0. Or how do I return a 1 for Sum fldDevider if it is actually 0.

This 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.

In my application, I open a "Customer Details" form and on confirming I have to delete all records from other 2 tables (Order & OrderDetails) of the database. I am not able to delete records. It somehow stops by on - ordDetAdap.Update(ordDetDs) . The code is as follows :
[Code]...
There may be N number of Orders and each order may have N number of OrderRedetails. There are rows and also shows proper data in MsgBox, also row.Delete works fine, BUT why does it stop at Update(OrdDetDs) I can't make out. Any idea where am I going wrong.
Also Is their any easy way out to delete all records using just a single statement providing OrderId from OrderDetails table ? As of there are 10 rows of a single order, then For loop will iterate 10 times and delete 10 rows, instead if I can delete all 10 rows at once would be beneficial.

I am currently writing a program in vb.net that will read and write to an exel sheet using OleDbConnection. I can read in from the file fine. When I save to the excel sheet and open it, the changes are there, however, when I close the file it asks me if I want to save, which makes me assume that the changes are not saved even thought they show up.
Below is the code I am using:
Dim conn As New System.Data.OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=" & excelPath & ";" & _

I am trying to load a small decimal number (eg 0.0566897 from a dataset field in to a variable (double), divide it by 2 and place it back in the dataset. After the divison, the variable is 0.0 and the rest of the decimal places are gone. How can I avoid losing the decimal places?
Dim dblCostps As Double = "0.0000000"
dblCostps = todds.Tables("todinfo").Rows(1).Item("cost_per_second")
dblCostps = dblCostps \ 2
todds.Tables("todinfo").Rows(1).Item("cost_per_second") = dblCostps

I'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

Simple 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?

I 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.

coding a shipping application where it adds .75 for every 100.00 dollars it would look something like this
0.00 to 100.00 = .75
100.01 to 200.00 = 1.50
200.01 to 300.00 = 2.25
300.01 to 400.00 = 3.00
and so on where the equaled value goes up .75 everytime i think i could use integer division and/or modulus
