MessageBoxes are often used to display error messages and other information, and I thought that I'd create something to make it easier to see the format of the MessageBox rather than having to test it or temporarily set a condition in order that you ca see how it looks and then modify the code. This is hardly perfect, but I don't think it's a bad start.[code]....

I am in the beginning stages of writing a VB.NET application for our customer's pc.This app will monitor machines through a serial port and display the status of those machines on the screen. In the future, we want to be able to run this program both on the pc and from any computer connected to the internet. What steps should I be taking now to make the web access step easier to implement?What is a good resource for learning how to make an application web accessible?

Given the image below
1. I have updated the image based on feedback from Steven_W so there are 4 triangles in the right hand diagram instead of 3 which makes more sense!
2. update image again to label sub triangles as A, B, C, D in grey
What is the pseudo algorithm for mapping a coordinate (x,y) in the left hand square such that a coordinate (u,v) is produced within the rectangle bounding the triangle on the right so that points are interpolated between the mapping points as illustrated on the diagram? 1 to 4 are equidistant on the triangle from left to right even though my illustration is a bit rough around the edges :)This is to generate a rough and ready panel for the lid of a skybox from the top half a 360 degree panoramic photo.
update 3 based on feedback.The first step appears to be working out which triangle we are in for the left hand diagram based on the (x,y) coordinates.The second steep is to work out the distance along the vertices of that triangle. Then use those distances to get the coordinates on the related triangle in the diagram on the right
update 4 - code to identify triangle in left hand diagram
Public Function TriangleIndex(ByVal x As Integer, ByVal y As Integer, ByVal w as integer, ByVal h as integer) as integer[code].....

I am working on a program where I need to read files. I won't know how many buttons I need until run time. I can't figure out how to create a button class I can call at run time. Each button will represent a file. I want each button when clicked to open the correct file and place the data into a rich text box on the form.Also, I need buttons to appear tightly in a row or multiple rows.

a common VB.NET class should look like the following:
Public Class MyClassName
End Class
Besides, I have already seen, if I remember correctly, all of the import statements visible just like in C#:
Imports System
Imports System.Data
Imports System.Linq
Public Class MyClassName
End Class
How to make these default imports visible by default in VB.NET using Visual Studio 2008?Is there some setting or the like in the options I shall set?

Is there any way to make a class instance public?In my mainform I define an instance of a certain class and then later on in some other forms which appear I want to alter this class.I try and pass them through when creating new instances of these other forms and it tells me Error3<instance of the class I want> cannot expose type <the class> outside the project through class <the form I want to edit it with>Which I gather from documentation is about it defeating the purpose to have a private class suddenly be thrown aroudn.but then how do I make it public? I can't define it in the first place as public myXClass as XClass, it only accepts private.

I am a java developer that inherited a vb.net web application. This app relies on a VB class assembly that builds in to a dll. I have made some changes to this class assembly but I cant seem to get the vb.net app to pick up the changes. I thought that using regsvr32.exe or regasm.exe would do the trick but after reading a bit more they don't appear to do what I need.
When vb.net uses code such as this import where is it getting the reference to "MyClassName"?
<% Import namespace="MyClassName" %>
