I have seen numerous dvd playing apps that when you insert the dvd into the drive is displays the movie name. Im looking to implement something like this. I want to show a desktop alert showing the movie name when it has been put into the drive so the user can add it to the collection.
I have "googled" around for this and have found nothing on reading DVD info. how to get the dvd info from a drive?

View 1 RepliesI am using BinaryWriter class to write a binary file to disk. When I invoke the Write method, passing an unsigned short value, it writes it in little-endian format. For example:
bw.Write(0xA000);
writes the value in the binary file as 0x00 0xA0. Is there a way to make BInaryWriter use Big Endian? If not, is it possible to create a new class, inheriting BinaryWriter and overload the Write function to make it write big endian?
Public Class Form1
Public Contestant As New ContestantClass
Public HighScore1 As New ContestantClass
Public HighScore2 As New ContestantClass
Public HighScore3 As New ContestantClass
[Code] .....
The problem I'm having is the first time I take a value, it gets inserted in the right section. The second time I insert a value, it inserts it in the correct place AND updates the previous value I inserted with the new value. So apparently when I'm doing:
HighScore1 = Contestant
It's pointing contestant AT highscore1 rather than taking the name, company, and score from contestant and then storing it in highscore1. How I can pass that info by value rather than by reference?
I'm building a class, and i let the user select several options to show or hide some features in another form.In my class i declared an enum with 5 values, and in one of my class constructors i declare an paramarray of the type of the enum.Now i want that when i declare a new object of this type, when the user put the "(" char, a popup/tooltip/intelisense (don't know what to call it), show all the options available. Like in the classes that allready exist in the framework...
View 7 RepliesI have an issue with StreamWriter class. Basically, in an application running as a web service, I need to write info into a log file. When I send 2 web service calls simultaneously, the entries created in the log file are not correctly written. For example,
in call #1, ID 1 - xyz is to be written to the log file. In call #2, ID 2 - abc is to be written. When I viewed the log, it shows ID 1 - xyz & ID 1- abc. Looks like there's some memory data being shared and mixed together, even though it's totally 2 separate web service calls. From my understanding, each call (i.e. each will be process under a different application instance) should have its own set of memory allocation for data processing... If I am to make this application as a Console Application, it looks like everything is processed correctly.
I can't seem to find any answers that work. Here's the setup:
Info class: Public Class ProductStageInfo

maybe I just don't understand the whole collection/index/thing. All the examples I've found are regarding single dimension collections - 'how to find name within this collection', and the responses use strings to search through them, but somehow the Info class is being treated differently, and I'm not sure how to translate this..
I am trying to speed up the development phase by using codesmith for generating the business class DAL and info class for the tables of my project. There are about 50 tables with relationships parent child many to many and for retrieving data I have to code several inner joins in stored procedures. I have to combine fields from many tables and this makes working with the info class difficult. Is there anyway to generate info class from stored procedures or to be more exact is there a way to parse the result set of the stored procedure and to generate the info class with properties for every column in that result set.

View 1 RepliesI want to store additional information about a listview item using a custom class, but I can't seem to get it to work.I'm currently using this code to accomplish something similar using a listbox item.I just want to do the same thing with a listview.

I wish to put the XMLSerializer behind a 'facade' class of mine so that user wont have to supply type info to the constructor. But doing this has a problem. Consider this class:
Class XmlFormatter
Private Shared xs As XmlSerializer
Public Function Deserialize(ByVal serializationStream As Stream) As Object
Dim o As Object = Nothing
[code]....
The problem is that the user of this class cannot use Deserialize without first using Serialize because the XMLSerializer instance is created in Serialize and it is shared. But using Deserialize without this instance will simply return Nothing.
I'm trying to pass data from the main form to a business class form for calculation.I have 3 types of cars and I can't get the code right to pass that to the business form. It seems correct to me, but obviously, it's not.This is the code for the calculate button, I can't figure out why its telling me that CarSize is not a member of the business form when I have it in the Enum statement at the top. I'm going by what the book says and this appears right according to it.
Dim CarTypeInteger As Integer
'determine the car size from radio buttons
If LuxuryRadioButton.Checked Then
[code]....
In the book it says to specify the class name when declaring the enum on the business form. So to me it looks like it should be -RentalRate.CarSize.Luxury The error I have is 'CarSize' is not a member of the 'ChristiansCarRentals.RentalRate'.

how to correlate info from a textbox based on a listbox item selection. For example the user will select an item from the listbox, enter say the length of a song in the textbox say 2:00 for song #1, select say song #2, enter the song time for that song say 3:00, click on song #1 again and have the same textbox display the length of that song and be able to do that until there are no more songs on the list.
View 5 RepliesOur main application has both a asp.net and winforms component. There is a class that is used by both sides and needs info from either the web.config or app.config files. The class itself does not know if it's on the client side or on the web server (at this point). We are getting errors when it's attempting read app.config when it's on the web side. Is there a way for the class to tell if it needs to read web.config or app.config?
