VS 2010 - How To Create Small App To Store Music Collection
Jun 17, 2012
I am a beginner on Visual Basic but was able to create the 'skeleton' of the application I need to build. Basically, it is an application dedicated to keeping a check on the vinyl I have. When I buy a new record, I want to effectively 'Add New Record' on Visual Basic and be greeted with a page consisting of various forms such as 'Artist' and Title'. Once these are filled in, I want to click 'Enter' and for all that information to be converted to one of the pages within my application.
Here's an easier look at it...
There are LPs that have 10" and 12" sections.
There are singles that have 7" and 12" sections.
In the 'Add New Record' page I want to also have a drop down list with the above elements in, once 12" LP is selected and all the other forms are filled in and I click 'Enter' - I want the application to send it to the 12" LP section of the application.

I have an application that uses Dataset.WriteXML to create a small backup before data is syncronized to a data store (less than a meg).This application has worked well for 5 years now, and all of a sudden with the installation of XML 6.0 SP2 the XML document is not working correctly.I have multiple tables within a Dataset (Company, Contact, Notes, etc...)When WriteXML is called, the first table should be Company, however, the first table is being named Contact with the Company Data in it. The Notes table is being called Contact and so forth. In other words it's not giving the correct names to the tables in the XML File.This appears to be a bug, which is causing great distress on all the companies who have been using this program.

I have been given the following informationA user owns a collection of music CDs and wishes to store information about them on a computer. For each CD the user wants to store:
* title
* genre (type of music)
* artist
[code]....
And here is what I am trying to doCreate a CD database - divide into tables with appropriate fields, primary keys, and foreign keys. Put in enough data to show that it works - say, five CDs with three songs each. You may make up the data or take it from real CDs. Use the CP212.mdf.zip file to create your database. (Ignore or delete the other tables in the file.)I have already done a similar task with student database. Where we made Course table, student table, student course table and subject table. We had to register a student in a student course by joing studnet info and course info. All I wanted to know what table am I suppose to make t

I'm trying to create a small game in VB2010. The gameplay is as follows:
civilians would walk/stand in a room/street and suddenly an evil character would pop from the ground/wall. This evil character would suddenly vanishes too. So, the player has to shoot it to kill the character. The evil character, civilians, etc. would be random. Also, there would be sound effects too. That is the popping up of the evil character, it's voice, the civilians voice, etc. I'm trying to make it as simple as possible but without degrading the quality of the game play. I think, I could somewhat create the graphics for the characters, scenes, etc. and can get the sound effects recorded.
So, the difficult part is,[ ] how could I make it a smoother for playing the game ?
[ ] what would be the best way to do animations ?
[ ] Creating a GIF and placing it in the picturebox and moving it ?
[x]how to play the music in background and at the same time play sound effects on certain instance ?

In the mvc 3 music store example they do the following.
Public Class Album
Public Property GenreId AS Integer...
Public Overidable Property Genre as Genre
End Class
Entity framework seems to be pretty slick and picks up that GenreId is the PK for the Genre table. So the SQL table for "Album" has GenreId as a column and when we load the album storeDB.album.find(x) it will also load the "Genre" entity. My question is, what if we wanted to have a second object of the same type. so for example, what if each album had a primaryGenre and a secondaryGenre. i would think that we could do something like this.
Public Class Album
Public Property MainGenreId As Integer
Public Overidable Property MainGenre As Genre
[CODE]...
And i have also tried this...
Public Class Album
Public Property MainGenre_GenreId As Integer
Public Overidable Property MainGenre As Genre
[CODE]...
However, none of these options are working properly. can anybody point me in the right direction such that when i load the album through storeDB.album.find(x) it will automatically populate the MainGenre and the BackupGenre?

Basically i am creating a console application that will create and store client information as a .txt file it is going okay but i have come across a slight hick up i want to use something on the lines of this .....
dim lastname as string
Do Until Integer.TryParse(Console.ReadLine(), LastName) = False
Console.WriteLine("Invalid input, Please try again")
Console.Write("LastName:-")
[code].....
this works fine to trap out numbers from letters but the problem i am getting is when the program calls uppon LastName it is recording 0 and wanted to know if there is a way of getting past this ..... so basically i need a way to allow letter but not numbers and symbols and then dispay a pernolised error message but at the same time use Stream writer to save was the answer is in a .txt file.

I like the PHP way of doing things but, it seems I am stuck with using a Collection of Object's to store/retrieve the data I need. I have my Collection loaded with my Objects's and the code to iterate through the collection, my problem is I am unable to retrieve the "key" as it would be called in PHP (I believe in this case it is actually the name of the object).
Consider the following example:
Dim xDoc As XPathDocument = New XPathDocument(fName)
Dim xNav As XPathNavigator = xDoc.CreateNavigator()
Dim sender As XPathNodeIterator
[CODE]...
As you can see, I am navigating an XML document, and creating an Object with some Key/Value pairs. The Object would look something like this if it were in JSON:
{"name":"John Smith","address1":"123 Anywhere St.","city":"This City","state":"FL"}
When I iterate though the Collection I can only get the value of the object, but I need the Key, in this instance I want "name","address1","city","state" to be stored in a variable for each iteration.

I am using VS2008 Pro. I have a simple DVD database built. I'm trying to make a data driven app to store my dvd collection.One of my tables is Actors and is structured as follows.[code]On a form in my app I have a combobox. I'm trying to make it list FirstName LastName ie. Will Smith. I know how to make a query that'll take the LastName and FirstName fields and list it as Actor. I'm having a heck of a time getting it to do that in the combobox as it'll only let me use one field for the display and won't let me use the query I've made.[code]I keep getting some error about schema don't match default query. I know I could simply change the table to only have one field that holds first and last name, but from what I understand that's not proper db practice. I've searched this site and google until I was blue in the face at looking at soulutions that don't match what I'm trying to do.

I need to Store Objects with Key like:
Key: <Fontname & FontSize> / Object: <Font Object>
Example content:
ArialRegular8 | <Corresponding Font Object>
ImpactItalic10 | <Corresponding Font Object>
TimesRomanRegular12 | <Corresponding Font Object>
These font types come from an external library, the real type is DocumentFont, I prefer not to store just values and recreate the font object later, so I need to store the object, and i want to be able to call Contains() later without looping. like for example Dictionary (of T Key, T Value), is this the best option? Also, to be able to call Contains(), i will have to overload function Contains() using an Interface or this is already built-in in some Collections / Dictionaries when using a String as Key?

I would like to store references to a bunch of structs in a collection. The general scaffolding looks like this:
Structure myStructType
Dim prop1 as String
Dim prop2 as int
End Structure
[Code]....
now this doesn't work, because it's referencing the same memory. What I would really want is the 'pass reference by value' behaviour that is also used for reference types, so that I can easily keep producing more of them.
Is there any way to fix this other than to make the structs into classes? Is this actually a proper way to use structs, or do I have it all wrong?

I am very new to collections and most of the applications that I build are Create, Read, Update and Delete type applications that don't really need arrays so I have almost no experience with either.
This is what I have so far.

Dim DayNumber(iDays) As Integer
Dim EmployeeRecords As List(Of String) = New List(Of String)
For i = 1 To DayNumber.Count - 1

Hey guys, I'm a new guy in VB.NET. I am proposing my final year project a title called music studio. My version of music studio is like real music video where we can play many sound at any time. For example, the application that I want to build can create many button and also add an audio along with it. And then, when we hit the 1st button, it play 1st audio. while 1st audio play, we also can hit 2nd button and 2nd audio is playing. for example, 1st audio is sound of man walking, and then 2nd audio is the sound of glass break. lastly 3rd sound sound of police siren play. Is it cool? so, my question is, is it possible the I can build an application by using VB.NET?

"Create a class called Invoice that a hardware store might use to represent an invoice for an item sold at the store. An Invoice should include four pieces of information as instance variables--a part number (type String), a part description (type String), a quantity of the item being purchased (type Integer) and a price per item (Type Integer). Your class should have a constructor that initialize for each of the four instance variables. Provide a property for each instance variable. If the quantity is not positive it should be set to zero. If the price per item is not positive it should be set to zero."
I attached the code I have. obj is underlined and says "Argument not specified for parameter 'Invoice4' of the 'Public Sub New (Invoice1 As Object, Invoice2 As Object, Invoice3 As Object, Invoice4 As Object)' and so the program won't run. What am I doing wrong?
Public Class Form1
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs)
Dim obj1 As New Invoice(Val(TextBox1.Text))
TextBox1.Text &= obj1.Invoice1 & vbNewLine
TextBox1.Text &= obj1.Invoice2 & vbNewLine
TextBox1.Text &= obj1.Invoice3 & vbNewLine
TextBox1.Text &= obj1.Invoice4 & vbNewLine

I'm trying to create a program that will manage and organize my music (mp3) files. So I used a ListView (SongList) to show the files that are in my music directory. Then I'm using a class found online to get the Title, Artist, and Album. Then it will insert it into the ListView and assign it a tag with the same value. But then when you hit the button to start the organizing the real problems start.
What it is suppose to do is check if the chosen directory exists then if it does it will create a folder for the artist of the song it is processing then a folder for the album then copy and rename (title) the song into that folder, then move onto the next song. But when it tries to create the directory it says there are invalid characters but there aren't. Also for some reason it wont put the Album name into the string for the directory???
Heres the function used to do just about everything:
Code:
Function CopySong(ByVal SongPath As String, ByVal SongName As String, ByVal SongArtist As String, ByVal SongAlbum As String)
If System.IO.File.Exists(SongPath) = True Then
Dim RootDir As String = "C:UsersCalebDesktopMusic"

I have an old VB6 application. I want to recreate it in VB.Net using WPF. But I am a bit confused about the "Model View Controller"-pattern. I have two books about design patterns (GoF and J.Bishop) afair this pattern is indeed not mentioned inside one of the two books. I have also searched the internet I found some java-examples. But I have still no clue how I should use MVC-Pattern (should I?) in my new WPF-application.Let's say for example my model (in fact it is more complex) is only a wheel rim (circle) with the properties Manufacturer, Diameter and Depth. The user should be able to modify the properties using textboxes and ComboBoxes.Could somebody create a small example that explaines the MVC-Pattern with WPF?Of course I like reusable classes to have a feasible concept throughout the whole application.

After casually creating a program to manage media (music, films, photos etc.) I came across a lack of functions that could be solved be being able to identify the length/ genre/ album/ artist of the song in question. find these file attributes (using a database is out of the question due to lack of resources).I'm reading the song into a string array from the folder they are contained in with the code:
My.Computer.FileSystem.Getfiles(FolderPath).copyto(MusicArray,0)
