I am currently in the process of converting a program I have developed from VB6/VBA to Visual Basic.NET. The object of this function is to run a query on an SQL Server Hosted database and output the results to Excel. I have a couple of last final problems though, in the old vb6 lines:

I found some code on the net that is supposed to convert a BMP file into a AVI file.

The example is in C# so i converted it using a C# to VB.NET converter and fixed a few of the conversion bugs. The code executes but fails on the line 'Throw New AviException("error for AVIFileOpen")' saying 'AVI exception unhandled'.
I have some code, that I am converting from C# to VB, in the code is the following line.
int index = ((int)document.GetCharAt(wordOffset +1)) % 256
that translates to something like this:
Dim index as Integer = CInt(document.GetCharAt(wordOffset + 1)) Mod 256
The problem is that the GetCharAt() function returns a Char type (pretty obvious from the name). VB throws an error saying that Type Char can't be converted to Type Integer. So my question is, what is the result of the explicit conversion in C# code?
I never used delegate before Currently I am converting some C# code to VB.NET and am having some issue, it says

I was trying to figure out how to convert a string (that the user would input to the program via a textbox) into actual code for the program to compile. For example, if the user was to enter: (5*100)+(20-3). How could you take that inputted string, and have the program solve it and return the value?

All the automated, online converters weren't able to convert this code. Unfortunately my brief knowledge of C# has also let me down. The code originates from a blog, linked from another of my questions.

I need to convert a VB.NET colour to a hex code.Here is my code thus far:
TextBox1.Text = ColorTranslator.ToHtml(Button1.BackColor)
The back color of button 1 is red. However when I use this code the textbox types "red" instead of "#ff0000". Is this because when typing HTML, most normal people would type:
<font color="red">
<!--- Instead of typing --->
<font color="#ff0000">

It works well in VB6 but throws error when i VB.Net..
I am having trouble converting some code from VB6 to VB.NET (I don't have as much experience with .NET). When I run the 'Select function (from the WS2_32.dll library) in .NET, using the same parameters as the VB6 program, it returns a result of -1 (indicating an error). I think the error may be related to an upgrade comment I saw about marshalling, but I was not sure what I needed to do to declare the function differently. Here is the code that I believe is related to the problem (including the upgrade warnings from Visual Studios):
<StructLayout(LayoutKind.Sequential, CharSet:=CharSet.Ansi)> Private Structure FD_SET
Dim fd_count As Integer
<VBFixedArray(FD_SETSIZE)> Dim fd_array() As Integer

We use a number of VB6 DLLs in classic ASP, using Server.CreateObject in the ASP page. The DLL code has recently (as a test) been converted to VB.Net 2008, and all the obvious issues that usually arise have been dealt with, meaning we are now able to use a .Net version of the DLL in classic ASP using interop (by using regasm to register the assembly for use in COM). The code that the converter added to the objects to make them usable in COM was <System.Runtime.InteropServices.ProgId("My.ObjectName")>, just before each class definition.
We have started noticing an inconsistent performance issue when using this new version of the DLL vs. the VB6 version in that it can sometimes take much longer to perform some tasks (even the task of constructing the objects from the DLL). In fact the same unit of work, including some DB work - now through interop ADO - can vary wildly (This is not limited to ADO work though!). We have started looking into this to try to figure out if it's some constant source of inefficiency, or if it's a load issue (threading related maybe).
I cannot seem to find a straight answer to the issue of threading when converting the code base. The DLL in VB6 is configured to use "Apartment Threading", the only other option being "Single Threading". Is this something that requires attention and is relevant when converting to .Net given we are still using the DLL through COM, and does anyone know what needs changing/configuring/checking?
I was wondering, is their any way to change a string into a line of math code. I was working on a graphing calculator project and am having trouble splicing up everything into variables and coefficient and operators. Example, having this block of code work

Would it be possible to basically make a full web page appear in a windows form application as an image? Sort of like a print screen command, but just for the web page itself. I need this to show any web page in overview as a image in my program, but I have no idea how to go about this. I suppose it would be almost like a web browser; other then that you can't click links or interact with the page at all, as it is an image. Preferably without loading the web page then converting it, but having it as in image as you load any given page - not sure if it's possible with just VB. Even a rudimentary method would be much appreciated.Note: I'm not to great with VB, so if you don't mind, please provide as much detail as you can with any given code,

using the Developerfusion tool here but I am getting multiple errors that I cannot resolve with my limited C# experience.
1) After getting errors I converted System.Runtime.CompilerServices.Extension to Global.System.Runtime.CompilerServices.ExtensionAttribute which is the closest I could come up with, and I get errors on the line (26)

2) Around line 196 handler = Function(sender, e) EAPCommon.HandleCompletion(tcs, e, Function() e.Reply, Function() ping.PingCompleted -= handler)
I get an error on 'ping.PingCompleted' saying'Public Event PingCompleted(sender As Object, e As System.Net.NetworkInformation.PingCompletedEventArgs)' is an event, and cannot be called directly. Use a 'RaiseEvent' statement to raise an event.
