OleDbCommand Named Parameters And Order Of Addition?

Apr 8, 2012

I have an ACE OleDb connection to an accdb file that�s working well but I�m mystified by something I recently discovered when using named parameters. Order of adding of parameters overrides the parameter names. I see in the MSDN that is states when in "Text" mode named parameters is not supported. My testing has proven this to be the case. The example below puts "Value 2 in Field1 and "Value 1" in Field2. In fact I could change @value2 to @blahblah and it works.

Dim command As New OleDb.OleDbCommand("INSERT INTO Results(Field1,Field2) Values(@value1,@value2)", con)
command.Parameters.AddWithValue("@value2, "Value 2")
command.Parameters.AddWithValue("@value1", "Value 1")

what is text mode and how do I change it and what other types are there? According to John McIlhinney�s earlier explanation things like date variables are added in a binary fashion including support for DBNull. So this is not "Text" so how am I sending binary data to a Db in Text mode? I�m just not getting why it supports names when it ignores them. Is it simply the case that there is no way to add parameters out of order in my case?If adding out of order is impossible should my command use some other syntax? I see other syntax that just uses question marks in the command dim for the Values section. EG "Values(?,?)".

Is there a way of adding parameters without names?In general I�d love to hear someone to explain this so I can understand the inner workings here a little better and have a little more confidence in what I�m doing here. I can fix my code to work but I feel like an idiot using parameter names that are ignored. I just know I�m doing something wrong even if it works.

.net - Differences Between C# And VB Handle Named Parameters?

Feb 25, 2010

Now that C# supports named parameters, I was checking to see if it was implemented the same way VB did it, and found that there is a slight difference. Take for example a library function like this:

public static void Foo(string a, string b)
{
Console.WriteLine(string.Format("a: {0}, b: {1}", a, b));
}

[code].....

The way VB does it requires much fewer instruction calls, so is there any advantage to the way C# implements it? If you don't use the named parameters, C# produces the same thing as VB.

EDIT: Now that we've determined that the extra instructions go away in release mode, is there a particular reason for them to be present in debug mode? VB acts the same in both modes, and C# doesn't insert the extra instructions when calling the method normally without named parameters (including when you use optional parameters).

VS 2010 Optional And Named Parameters In An Attribute?

Sep 7, 2010

I have a custom Attribute class where the constructor takes one fixed parameter and two optional parameters. It is my understanding that one can supply one or more optional parameters by using 'named parameters' such as this:

Private Sub CallMethod()
Me.OptionalMethod(-1, z:=1)
End Sub

[code]....

Well, I thought, perhaps Attributes don't support named parameters. I know they can behave a little weird (they don't support all types in their arguments for example I think), so I thought little of it.But then... I noticed something else. If you take a look at my code of the attribute class again. Notice that I am using an attribute on that class as well... And what do you know: named parameters. Working just fine... The AttributeUsage attribute has the exact same configuration: one fixed parameter and two optional parameters. I seem to be able to call them using named parameters just fine, where I cannot call my own attribute constructor with named parameters...

Is it possible to use "IN" operator together with OleDbCommand.Parameters.AddWithValue ?

I am using Visual Studio 2008 and Microsoft Access 2000.

I have search online but find no solution on it. Below is my code:

Where there is 2 Document No inside parameter @Doc , i can't get any of them. When there is only 1 Document No, then it is ok.Is it possible to use "IN" operator together with OleDbCommand.Parameters.AddWithValue ?

OleDbCommand Select Returning Null

Feb 16, 2011

Having trouble importing a value from a .csv file to a .csv file. This this done because data needs to be massaged and the data file renamed. This is a user interface. Do not want to have the user touch the .csv in any way except upload to the application so the applicaiton can do manipulation. Either way here is the issue.

There is a column in the original .csv file that contains a zip code. The first row of the .csv has a value of 17003 in the zip code column. In the second row of the .csv the zip code column has a value of 11746-9984. The value in the zip code column from the second row always comes back as a Null value. My guess is that the OleDbDataAdapter is defining some kind of Schema. Again, the first row containing the zip code column probably insists the value must be numeric. When the data table field is established it probably gets defined as numeric. If that is true and the second row of the .csv zip code column is not numeric that must cause the zip code value to be Null.[code]...

Oledb - SELECT Through Oledbcommand In .net Not Picking Up Recent Changes?

Sep 28, 2009

I'm using the following code to work out the next unique Order Number in an access database. ServerDB is a "System.Data.OleDb.OleDbConnection"

Dim command As New OleDb.OleDbCommand("", serverDB)
command.CommandText = "SELECT max (ORDERNO) FROM WORKORDR"
iOrder = command.ExecuteScalar()
NewOrderNo = (iOrder + 1)

If I subsequently create a WORKORDR (using a different DB connection), the code will not pick up the new "next order number."e.g.

iFoo = NewOrderNo
CreateNewWorkOrderWithNumber(iFoo)
iFoo2 = NewOrderNo

will return the same value to both iFoo and iFoo2. If I Close and then reopen serverDB, as part of the "NewOrderNo" function, then it works. iFoo and iFoo2 will be correct. Is there any way to force a "System.Data.OleDb.OleDbConnection" to refresh the database in this situation without closing and reopening the connection. e.g. Is there anything equivalent to serverdb.refresh or serverdb.FlushCache

How I create the order.I wondered if this could be caused by not updating my transactions after creating the order. I'm using an XSD for the order creation, and the code I use to create the record is ...

Sub CreateNewWorkOrderWithNumber(ByVal iNewOrder As Integer)
Dim OrderDS As New CNC
Dim OrderAdapter As New CNCTableAdapters.WORKORDRTableAdapter

Re Order Column Order In A Data Bound DataGridView?

Apr 17, 2010

I have a databound Datagridview. The DGV is bound to a datatable of a strongly typed DataSet created using the wizard. Is there any way to re order the columns before displaying them eg: the Columns are displayed in the DGV in this other Col4, Col6, Col3, Col1,Col5, Col2

But I want to it to show as Col1, Col2, col3, Col4, Col5, Col6?

I realise that the display order followed the Column order in the database table and by extension, the datatable. I have re-arranged the columns in the Database but the Datatable still retains the old order.

I should be able to get result back as long as there's a match in the parameters. If I use Function Contains (q.FirstName & " " & q.LastName).Contains(employeeName), I will not get any result back if employeeName is "John Clark" Function Contains looks only for next words from left to right. It doesn't match a single word at a time. So that's why I used this in the Linq to SQL:

.net - Unchecked Integer Addition In .Net?

Mar 8, 2010

I have a project where I want to have checked arithmetic by default, except for one performance sensitive spot. Unfortunately, VB.Net doesn't have an 'unchecked' block.Ideally the framework would have some sort of integer type with explicitly unchecked arithmetic, but I didn't find anything like that. I did find that expression trees have binary expressions for unchecked operations, but the delegate overhead cancels out the unchecked advantage (and then some).

Currently I'm converting the inputs to UInt64/Int64 before doing the arithmetic, then converting back (with a bitwise And to ensure in-range). It's about 50% slower than unchecked arithmetic (according to profiling).

Moving the arithmetic-sensitive part to a project with unchecked arithmetic might work, but it seems like overkill to give it an assembly all to itself.
