Conversion From C# To VB Work?

The original code:
public List<Contact> GetContactListEntityCompiledLINQ()
{
if (entities == null) entities = new CompanyEntities();
ObjectQuery<Contact> contacts = compiledQuery.Invoke(entities);
if (NoTracking) contacts.MergeOption = MergeOption.NoTracking;
[Code]...
Error 1 Extension method 'Public Function ToList() As System.Collections.Generic.List(Of TSource)' defined in 'System.Linq.Enumerable' is not generic (or has no free type parameters) and so cannot have type arguments.

I have the below code (which goes through the C: drive and gets file info data) and want to convert the length to a "respectable" number - i.e MB. The problem is that the line below does not do anything to the code.
Line is: strlength = strlength * (1024 / 1024)
Private Sub btnclick_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnclick.Click
Dim strFilesinfo As System.IO.FileInfo

I have this code below that I called a Conversion Wizard Because it converts temperature, weight and currency. It works so far but I am stuck. I don't know how to apply the correct loops to it. For example, Do While and Do Until. I want it to be able to work out a conversion then loop back to the Menu-options. So that you can do as many conversions as you like and end when option 4 is selected.
Option Explicit On
Module ConversionWizard
Sub Main()
Dim userOption As Integer
Dim farenHeight As Integer

I have a VB2002 program that works. When I run it in VB2008, it updates, and runs and debugs until I shut down. When I try to start it up again from the updated SLN, or try to run the .exe in the BIN folder, I get the message "This application has failed to start because the application configuration is incorrect.
I checked the error logs and it says there is a syntax error in the first line of the vhost.manifest file in the BIN folder. The first line is the xml declaration and it includes the parameter standalone = "yes".
When I put the error message into Google I only get references to Visual C++ compiled programs running on machines without the C++ redistributable dll. That doesn't seem to apply here at all, since I have the VB 2008 express edition installed on this

I'm creating a program in VB.net that does the following:At a high level I receive a file in email, put the attachment in a monitored folder, import the text file to excel, format the excel, and then email the excel file to a list of recipients.
Here is my plan:
Completed: Outlook VBA to monitor all incoming email for specific message. Once message is received drop attached .txt file in a specific network folder.
Completed: (VB.net) Monitor folder, when text file is added begin processing
Not Complete: (VB.net) Import text file to Excel
Not Complete: (VB.net) Format Excel Text file.(add in a row of data,format column headers with color/size, add some blank columns, add data validation to some of the blank columns that allow drop down selections)
Completed: (VB.net) Save file.
Completed: (VB.net) Send file to list of recipients.
Obviously the items above that are not complete are the bulk of the work, but I wanted to get some advice on what some of you think would be the best way to approach something like this. The import and formatting of the file are causing me some problems because I just can't decide what would be the most efficient way to do this.
The way stated above. Import to excel -> format Having a template excel that contains all of the formatting already done for me and attempting to transition the data to this document (no clue if/how I can do this). Is it even feasible? Have the template already created and then import the text file to a new excel file, then transition that data to the excel template?
Something I thought about, in terms of formatting the document, was to record a macro of me doing all of the formatting that I'm going to need and then attempt to convert that macro into my vb.net code, but I'm not sure if that will work. I will need to verify that the text file comes in the EXACT format every time correct?

I have an application that requires data be entered, and after entering, a button is clicked to process that data. Clicking the button works just as it should--the data is processed properly. In constructing a test module, I provide a set of data values, followed by:
btnWhatever.PerformClick()
Nothing happens. I have used this syntax for years, and it has always worked flawlessly. I have triple checked everything else and isolated the problem to the failure of the PerformClick(). The PerformClick() is in a test subroutine that does nothing but fill textboxes and labels with default data, then calls the PerformClick() on the button to begin processing. Again, the button works fine, the data is entered as it should be, but the PerformClick() does not fire the click event.

I have a snippet that I need help modifying to work in VB.NET.1. Attribute VB_Name = "DBModule" gives error 'Declaration expected'.Am I missing a library reference here?Also, the project conversion tool chokes on four statements, one of which is: "{F9043C88-F6F2-101A-A3C9-08002B2F49FB}#1.2#0"; "comdlg32.ocx"Can I simply find the file and place it in the project directory? How would I reference it then? Additionally, The project converter lists errors locating the following files: msflxgrd.ocx, AResize.ocx, richtx32.ocx, and msmapi32.ocx. TIA

public class FloatToolStrip :ToolStrip { private Form floatForm; public Form FloatForm { get { return floatForm; }} c# is case sensitive so floatForm and FloatForm are different.
vb.net is case insensitive so when the inline compiler sees FloatForm, it says it has already been declared.
how do I convert the blue code into vb.net?

I'm working on a cryptography program that was written in VB6 and modernizing it in VB.NET and I've run into a roadblock with the conversion from strings to byte arrays and then back again. I've tried a lot of stuff and it's probably something really simple.
The VB6 code used to look like this:
Public Function DecryptByteArray(byRef arrByteArray() As Byte, ByVal Password As String)
Dim strInput As String
Dim strOutput As String

I'm currently working for a client who owns a custom developed ASP/VB6/SQL2k5 3-tiered web application... The application has been developed over the course of 10 years by several different companies... I have a team who is in the process of rewriting components of this application over to a ASP.NET/C# applications, leaving the structure of the back end database in its current state (ie: no redesign of the database)... As you know, this is a very long tedious process when performed correctly... Our client is looking for a "wizard" type conversion tool or process instead of the redesign of the web UI and business objects... Several people on my team (including my architect and I) continue to tell our client this is not possible, that a full rewrite of the application is required... Can someone just validate my thoughts on this? Here are some of the technical specifications of the legacy application:
· VB COM objects are heavily reliant upon ADOR recordsets
· ~150k lines of VB code spread across 6 COM objects
