How To Play Sound Files In Desired Order According To Text Inputed In Txtbox?
Feb 26, 2010i got the following things:
-A button (called "btnplayvoice")
-A textbox(multi-line enabled, called "txtinput")
-Some *.wav audio files in my "resources" (2 of them called "A.wav" and "B.wav", of course there are still some more sound files in my resources xD)Note: the button and the txtbox are in the same form.
i want to make a program with this feature:When I type "B A"(note between "B" and "A" has a space)into txtinput, then i click the btnplayvoice, it will look up and check the resources and see if the wav file exists there, if yes, it will play the related(same as inputed) sound files one by one in correct order. That mean in this case I should hear "B.wav -> A.wav" in this order.

View 2 RepliesVS 2008 - Retrieving List Of Files From FTP Server?
Apr 26, 2010I'm using this code to retrieve the list of files from a FTP server
Dim request As FtpWebRequest = WebRequest.Create("[URL]")
request.Credentials = New NetworkCredential(username, password)
request.Method = WebRequestMethods.Ftp.ListDirectoryDetails
Dim response As FtpWebResponse = request.GetResponse()
Dim responseStream As Stream = response.GetResponseStream()
Dim reader As StreamReader = New StreamReader(responseStream)
messagebox.show (reader.ReadLine)
It gives me alot of information that I dont need, I know that I can use:
request.Method = WebRequestMethods.Ftp.ListDirectory
Which only retrieves the file name but when I try to change it, it gives me an error. Error number 550. ListDirectory so I can only get the file name?
VS 2010 - Retrieving Metadata Of Individual Files
Oct 6, 2011I'm using VS2010 Express. I have a VB.net project, where I need to find the metadata of individual files; Artist, Author, Comments, etc. (Specifically I need to find the video length in time of .wtv files). I have searched, but could only find VB6 examples and other code snippets that simply didn't work as they required some retired com or dll to do it. How do I do it in the latest VB.net? NOT VB6, C# or anything else. VB.Net in Visual Studio 2010 Express.

Retrieving A PIN Code From A Database?
Mar 11, 2009I am coding a banking and ATM application, which is split into two parts. In one part the employees of the bank can open new accounts for customers, edit accounts, etc. It includes assigning a unique PIN code for the customer. This is all saving to a database. The customer then uses the ATM part of the application to withdraw money. They use a unique PIN code to access their account. The problem that I'm having is retrieving the PIN from the database. I want to write a simple If statement, to match the PIN entered with the corresponding PIN in the database, so that it will retrieve all the relevant customer's details, eg. bank balance. The PIN is successfully saving to the database through the following....
Private Sub btnCommit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCommit.Click
If inc <> -1 Then
[Code]....
So how do I retrieve the PIN from the database that matches with the PIN entered and hence, retrieves bank balance, etc?

Retrieving The Correct PIN Code From A Database?
Mar 18, 2009I am having difficulty retrieving the correct PIN code from my database, for an ATM banking application. When someone enters a correct PIN code that is already in the database, they gain access to their ATM account. If incorrect, then a message box appears. I am having an unusual problem where, the system is partially working. The code I have, is preventing the user from accessing their account, in the correct manner, eg. message box pops up. However, it is also not accepting the correct PIN code. The most unusual thing about this, is that, if the user enters the number "1", the message box won't pop up, however it will still block the user from accessing their account. And even stranger again, after entering the number "1", trying it, then erasing it, if they enter the correct PIN after this, it will allow them to access their account.
Here is the code:
Public Class ATM2
Dim Pin As Integer
Public Sub Retrieve()

VS 2005 Retrieving Values From Database?
Jun 23, 2011Im taking over a project that pulls information from a database.Currently I have everything I need except the username.The person who setup the project did it as a web project so he used the MemberShip class to create unique user keys based on the person's username.
The username is not stored anywhere in the database only these userID keys.
The client wants a desktop app that mimics the website behavior of writing to the database.
Problem:I ask the user to enter in a username at the login. The username connects to the database on the server.I have no way of grabbing any user info after this point as the primary key(USERID) is a unique key and not a username. Is there a way to convert a MemberShip ProviderUserkey into a string Username or am I screwed?
