An Error "OleDbCommand.Prepare Method Requires All Parameters To Have An Explicitly Set Type"?
Nov 2, 2009
when I search for a customer, it can search but the problem is that when I search for customer and I wanted to update or delete, It has an error which says "OleDbCommand.Prepare method requires all parameters to have an explicitly set type." What does that mean? Here is the code that I am using:
Public Class EditingCust
Dim cmd As OleDbCommand
Dim myAdapter As New OleDbDataAdapter[code].....

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.

I am in the processing of moving an app from VB to C# but some of the classes I will just be moving to VB dlls to access from the main C# app. In doing this I am trying to get the VB dlls to utilize the main C# class lib. In this C# lib I have an abstract clase called base process, it sets up a background worker and handles all the progress tracking, errors, and even reports an ETA. To use this in a derived class in C# you would just do this...
public class SomeLongProcess : Common.Multithreading.BaseProcess
{
public void start()
[code]....
The problem is that if I do the equivelant in VB I get an error "Handles clause requires a WithEvents variable defined in the containing type of one of its base types". Well I can't do a WithEvents in the base class because it is C# so..

Is there a way to get an enum to explicitly cast to it's base type?If I have something like this:
Code:
Public Enum Packets As Byte
Stuff = &H0
End Enum
I have to do
Code:
Dim test As Byte = CByte(Packets.Stuff)
Rather than
Code:
Dim test As Byte = Packets.Stuff
I don't see why that's the way it works, since you know that the enum will always have values of the base type.

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:
Dim conn As New OleDbConnection
Dim cmd As New OleDbCommand
Dim Adapter As New OleDb.OleDbDataAdapter
Dim strSQL As String
Dim dsDoc As New DataSet
[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 ?

I am trying to over come this paoblem from last 2 days But i am not able to overcome.I was able to set up the environment so that I can call .NET method (via COM) from a classic ASP page.Everything actually works as intended until when I have to call a .NET method that requires a .NET type.So I have a method named SetTable Like Below I have a function like this in .Net
Public Sub SetTable(ByVal _City As City, ByVal _Country As Country)
'doing some thing
End Sub
and i have asp code like this:
dim CountryUtil, City, Country
set CountryUtil= Server.CreateObject("mydll.CountryUtil")
set City= Server.CreateObject("mydll.City")

I'm having a few problems converting some code into VB.NET from C#. Most of the translating is done, but I am getting errors when I try to run my code, and I can't figure out what is causing them. Here is the Sub I translated.
Public Sub CreateWidget()
Dim blue As LCDColor
blue.Red = 0
blue.Green = 0

The error I receive on this line ("vision.Widgets.CreateWidget(wg1)") reads "In order to evaluate an indexed property, the property must be qualified and the arguments must be explicitly supplied by the user."

I have an issue with a third-party COM+ DLL meant to be used from VB6, where it has a function to set a Callback for a hardware event. However, I'm using VB.NET, and AddressOf now returns a reference type instead of an integral type, which means that the setCallback function on the COM+ DLL apparently can't be used.

I am trying to print (to a text file) the fragmentation information give by Win32_Volume class using the DefragAnalysis method and have come up with the following VB.NET code:
Dim objReader As StreamWriter
objReader = New StreamWriter(FolderBrowserDialog.SelectedPath + "FragInfo" + "_" + CreationDate + ".txt")
Dim colItemsFragInfo As New ManagementObjectSearcher("rootCIMV2", "Select * from Win32_Volume where DriveType = 3")
[code]....
You do not need to defragment this volume.However executing this in Visual Studio returns the below:
Volume size: MB
Cluster size: MB
You do not need to defragment this volume.The point here is though it does NOT work under Windows Server 2008 R2, but does work under Windows Server 2003 (when executed in Visual Studio), WMI Code will work regardless of platform.
NB: i have played with the "Console.WriteLine" and changed it to "Debug.WriteLine" to output value to immediate window.

I got 2 classes in a form, and I would like to pass a value from a textbox to the other class, so I decided to use Deligate.
Below is the code.
Public Delegate Sub delPassSize(ByVal text As TextBox)
'To get size from Class Calculate(Class 2)
Public Sub GetSize(ByVal txtForm1 As TextBox)

and the error message is 'cls.Getsize is a delegate type and requires a single 'addressof' expression as the only argument to the constructor.'

I am writing a alternative to GDI, and rigth now i am working at a logging function. The idea is that while you use the class to draw, it will write a logg of what you have done, which can be used to draw it back later. In that way i would be able to store a drawing with weary little disk usage.
