.NET Outputting Method Parameters?
Feb 19, 2011
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 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.

How would I go about passing parameters to a method? I would want to do the following:
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
ReceivingUdpClient = New System.Net.Sockets.UdpClient(6767)
Dim receiveBytes As [Byte]() = ReceivingUdpClient.Receive(RemoteIpEndPoint)
Dim ThreadReceive As New System.Threading.Thread(AddressOf receiveMessages(receiveBytes))
ThreadReceive.Start()
End Sub
Private Sub receiveMessages(ByVal receiveBytes As Byte())
'INSERT CODE

End Sub

I have an inline lambda expression that I would like to use throughout my application. I just can't seem to find a reference on how to do this with more parameters than the element being tested. Here is a quick example of what I currently have.
Private Sub Test()
Dim List As New List(Of String) From {"Joe", "Ken", "Bob", "John"}
Dim Search As String = "*Jo*"

Is there a way to create a method with unknown number of parameters? And if it this the case: How is it possible to get access to them within this method? Do they have to be from the same type?

I have the following test method (VB.NET)
<RowTest()> _
<Row(1, 2, 3)> _
Public Sub AddMultipleNumbers(ByVal number1 As Integer, ByVal number2 As Integer, ByVal result As Integer)
Dim dvbc As VbClass = New VbClass()
Dim actual As Integer = dvbc.Add(number1, number2)
Assert.That(actual, [Is].SameAs(result))
End Sub
My problem is that when the test runs, using TestDriven.Net, the three method parameters are 0 and not the values I am expecting. I have referenced the NUnit.Framework (v.2.5.3.9345) anf the NUnitExtension.RowTest (v.1.2.3.0).

I was familiar with the optional parameters in vb 6 and it made sense given the capabilities of the language but why the heck does VB.Net support optional parameters when there is method overloading? Which one should I use and is there a difference? If there is a difference when should I use each one?

A friend in work suggested the use on classe to store the parameters BEFORE call a method. He's said this is called "Abstract Class". My "know how" of VB.NET is small... so, I want to know of you what mode is the best way: Call a function/sub like that:

I have a COM component that I want to call using late-binding from VB.NET (using Primary Interop Assembly - PIA method). My IDL signature for the COM method looks like:
HRESULT Send([in]BSTR bstrRequestData,
[out]VARIANT *pvbstrResponseData,
[out]VARIANT *pvnExtCompCode,
[out,retval]int *pnCompletionCode);
So 2 'ByRef' parameters in VB.NET lingo, and a return value. I attempt to invoke this method like so:
Dim parameters(2) As Object
parameters(0) = "data"
parameters(1) = New Object()
parameters(2) = New Object()
Dim p As New ParameterModifier(3)
[Code] .....
This fails spectactularly with an exception: {"Invalid callee. (Exception from HRESULT: 0x80020010 (DISP_E_BADCALLEE))"}
I assume this means I'm doing something wrong in my parameterMods array. Because if I comment out setting any value of the ParameterMods array to 'True' - it works. It of course doesnt update the parameters that are [out] parameters and so it's not working as intended. Is there something else to consider since the method also has a return value? The MSDN example pretty much does exactly what I am doing, with the exception that example did not have a return value.

For example, assume that in my assembly, in Namespace A, Class B, there is an instance method with the following signature: void Test(string someString, int someOtherParm, string someOtherString ); This method is called multiple times, from multiple places in the assembly. I would like to be able build a list of all invocations of this method and the value of the someString/someOtherString (assuming they are hardcoded). In other words, I like to extract a list of calls like the example one below, if they happen in the assembly somewhere: Test("some text", 8, "some other text");

I've been creating short test apps repeatedly to try to understand some of the concepts in VB.NET.For the most part it has been illuminating.I read Bucky's .NET knowlegebase tutorial on passing objects as parameters to newly created forms. He shows how to create a new class that inherits from the base form class and define a New() method with parameters Extending the concept I thought about doing the same thing with a form that was created at design-time (In this case Form2).

I'm working on a program that allows me to quickly write database entries. There are 123 columns, almost all of them I'm not using right now so I figured I'd write a program to speed up the process of adding entries to the database.The problem I'm having is exporting every row in a DataGridView to a .sql file. I'm able to do it with a single row but I'm having trouble with doing it for all rows. Every time I get a index out of range exception.I can't figure out why. The problem is probably obvious, but I need a fresh set of eyes to figure it out.In order for it to streamwrite each line it first collects all the data from the columns by using a loop then it writes it, clears the string and starts on the next row, looping for all the data, so on and so forth.
Private Sub StreamAll(ByVal table as String)
Dim TotalRows As Integer = DataGridView1.Rows.GetRowCount(DataGridViewElementStates.Visible)
Dim CurrentRow As Integer = 1

I am stuck on trying to get the sum of numbers to output to a label. I have a label box lblTcost that I would like to have the total of my list box lstCost placed into there. I have tried several things and keeps crashing or just not working at that part. I have used the debugger but since I know the line is wrong any ways that not helping. I though this line would work lblTcost.Text = lstCost.ToString("c") was the proper way but it isn't. Here is my completed code
Public Class Form1
Private Sub btnAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAdd.Click
'Declare values from both listboxes
Dim Day, Fee, Stay, Total As Integer

I have a combo box that has multiple options, when the user selects one of the options (world wide city destinations) a specific value is assigned to a variable. For example if "New York" is selected the variable "x" is assigned the number 155. What I want to do is output the destination that has been selected ie "New York" in a label called "lblOutput1", do I need to store the destination as a seperate variable to be able to produce it in this label as I cannot seem to get it to work:
At the moment I am using:
lblOutput1.Text = "bla bla bla " + cmbDestination.SelectedText + " bla bla bla " + Today()

I've ported a page from classic ASP to ASP.net. Part of what happens in this page is that a collection of custom types is generated and then displayed via Response.Write() commands. I'd like to get the business logic separated out into a code behind file (and maybe move this all into a user control), but I can't seem to figure out how I'd actually display the collection once it's been generated. I want to specify a master page here, too, so the code can't stay inline. Here's a very stripped down version of the current code:
