I think VB has a way of doing this, but for the life of me I can't find it. I want to search through a string for anything contained between two certain characters, e.g between 2 | characters. I'm not sure if I want to split the string at this point, but I only want anything contained between the two | markers. So for example if the string reads |ABC|DEF I only want to retrieve the ABC, but not the DEF as it's not completed yet.

I am having issues finding resources detailing building Speech Recognition grammars using VB.NET, Speech.Recognition.GrammarBuilder, and .NET 4.0. I have found a few examples on the Internet, but they seem to just go over the basics. Does anybody know where I can find a good source on detailed information, as well as Speech development in general. I mostly see links to class definitions, but no explanations and discussions.

View 18 RepliesI'm writing software in VB .NET (2005) which uses the Windows user information as login credentials - just the username. I've found Environment.UserName which works for the username (as you would expect).However, I need more information - I need the full name of the user (as shown on the Start Menu). It seems this information is stored... somewhere, as Windows is able to use it for things like permissions on file shares.
View 1 RepliesI have an app where users form up an e-mail by filling out various fields. They give the form the data, then the e-mail is assembled in the background from all the data they put into the form. Pretty straightforward.
I've added a "Preview" button. When they click, I want a box to pop up and show them what their e-mail will look like when they send it.
I can use MessageBox.Show but these e-mails can get pretty long and as best I understand it, there's no way to control the MessageBox.Show size, word-wrap or add a scroller; so this isn't really appropriate to the overall task.
That said, the information IS all concatenated into a single string with CrLf and such in there for most fields. I just need something that I can send this to and have it create the output window at size X with auto-word-wrap and scroller.
Is there a straightforward way to do this in VB.Net 2010?

I am trying to store confidential encrypted user information for my program on a single computer. I do not want the application to be copied on to another computer and be usable. So I was thinking about storing the information in the Registry but I read that that is a very unsafe location and is bad for more reasons then one. I started storing the information in the programs Settings.config file but I am not sure how to encrypt that information. The only thing I have gotten to work so far is storing the information in a XML file and encrypting that which has worked but I want the information to be more hidden and more secured.

I need to know where the Install Shield gets the user information from?
This comes up on the last page of an install at the bottom.
User Information:
Name:
Company:
Does this information comes from the machine that is installing and if so where? or Does this information get stored in the installshield project? If so How can I change this?
I have changed two registry keys from:
HKEY_LOCAL_MACHINESoftwareWow6432NodemicrosoftWindows NTCurrent Version
RegisteredOrganization
RegisteredOwner
My application project was created before I made the change. I then deleted the install shield project and started over but got the same results..
For some reason my setup project says
user: Microsoft
company: Microsoft
I would like to change this to my User Information if possible.

Bifurcation:
f(x) = kx(1-x)
and k = xL + i * (xR-xL) / 500
when i runs from 0 to 500, it plots (i, f(seed)), (i, f(f(seed)), .... up to the boundary number.Here is what I have got so far. Everything seems normal, however, I am really confused when it comes to plotting.

I need to have the ability to have a Global variable/class that stores some basic information about the currently logged in user including that user's preferences, security rights, UserID, etc. This information will be needed by any/every part of my application. In the past I have either used a Public variable/class in a vb.net module for this purpose. I'm trying to get away from my old ways of doing things and was curious what people currently do for this functionality.
I am thinking a singleton or 2 regarding preferences and security but am not sure if that is the best way to go.
EDIT: I asked this when I was too sleepy last night. This is an n-Tier WinForms application.
I have a form that has several fields that needs to be filled in by the user. Once the user clicks on submit. What I want is to make all the information to clear after the user clicks on submit.

i want the user to login, and the first thing is, having the text document for that(if theres a safer way to do it, let me know) then it goes to the weekly sales page, but theres also the goals for the sales, which rarely change, but if they do i would like them to be able to change them, then next page is the list of the workers, and if they need to i would like them to be able to add workers. so my question is: is there anyway that maybe i could save both the goals, and the workers in the text document, and when they need to change it/add workers it will save it in the text document and the next time they sign in the changes will be permanent? also is there a way to delete the user once they have been created, other than going into the txt document and deleting it.
