ASP.NET MVC Music Store - Second Object Of The Same Type - Each Album Had A PrimaryGenre And A SecondaryGenre
Apr 12, 2012
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?
I am using VB .Net for this, so I don't have access to var or this would be a simple matter.Right now my query is as follows
[code]...
So I used this query in LinqPad to help me determine what the object would look like. I got back a IOrderQueryable(Of RSError) which then contained a IGrouping(Of String, RSError) for each grouped collection of objects returned by the query.However I ended up with the current object type of errors as IOrderedQueryable(Of IGrouping(Of String, RSError)) because of the cast error I am getting in VS.
[code]...
I'm not sure how to get rid of the VB$AnonymousType_1 Part of the returned object.Am I even on the right track here or am I missing something completely?
I'm working through the MVC Music Store in Visual Basic ([URL]), trying to convert things as I go. I'm heving trouble with some of the lambda expressions in the Views, however. Specifically, on page 53 when the Album editor template is used, I am not seeing my editor template when I use the following code:
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 want to use explicit conversion (CType function in VB.NET) to convert the variable d from double type to integer type and store the result as 132.
Imports System.Console Module Module1
Sub Main()
[CODE]...
This is my code. But Visual Basic tells me an error: Error1Type 'i' is not defined.C:\Users\mihaispr\Desktop\Conversie explicita\Conversie explicita\Module1.vb1922Conversie explicita

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?
I've got a piece of code in a project (MyProject) that contains early bound object from a referenced assembly (We'll call it CommonAssembly):
Dim myObject As CommonAssembly.MyEarlyBoundType
now I have another assembly that is dynamically loaded because it is not present in all projects:
Dim myLateBoundObject As Object = AppDomain.CurrentDomain.CreateInstanceAndUnwrap("Utils", "Utils.MyLateBoundType") MyLateBoundType derives from CommonAssembly.MyEarlyBoundType, and I want to cast myObject to myLateBoundObject and then programmatically invoke the additional
I am implementing IMAPI2 into my vb.net project but ran into a wall. I am getting the message Unable to cast object of type 'IMAPI2FS.FsiStreamClass' to type 'IMAPI2.IStream' when trying to start the burn. I googled around and found this is something that microsoft hasn't fixed.. which basically renders IMAPI2 useless in vb.net.
I found a post on codeproject.com by eric hadden who combined the IMAPI2.dll and IMAPI2fs.dll into an c# interop file. I also see the IBURN interop in microsoft SDK samples. I'd like to use either, but it's in c# and I'm using vb express. Does anyone know a way to get the interop into visual basic or a way around "Unable to cast object of type 'IMAPI2FS.FsiStreamClass' to type 'IMAPI2.IStream'"?
I'm having a problem with converting from one source type to a destination type. I have a form with 2 buttons (button 2 uses the OpenFileDialog to have the user open an excel file set to NewFile),(button 1 takes the contents from specific cells in NewFile and arranges them how I need into oXLApp1).
The error I get is "Unable to cast object of type 'System.IO.FileStream' to type 'Excel.Application'." in line 14 of the code below.
Public Class Form1 Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
I'm new to VB 2005, the code below is actualy coded from VB 6 and just converted it to VB 2005. I'm having trouble with line that's on bold letters.In VB 6 this works just ok. By the way the error message is "Unable to cast object of type 'System.String' to type 'ADODB.Connection'." [code]
Unable to cast COM object of type 'System.__ComObject' to class type 'rjsDocMan.Folder'.Instances of types that represent COM components cannot be cast to types that do not represent COM components; however they can be cast to interfaces as long as the underlying COM component supports QueryInterface calls for the IID of the interface.The code where it is flagging the error is:
I saw this thread and I had simple answer in mind. To use custom enumerator class. So I was trying to make one for that guy, which would have one more property to check whether its has reached end or not. It would also provide current position.I'm getting an error "Unable to cast object of type 'SZArrayEnumerator' to type 'WindowsApplication1.myEnumerator'." at the line 6 [see below].However, return type of values.getEnumerator says its IEnumerator.

Columns 0 & 1 are filled from a DataAdapter from Access Database and three are added. I had this working, but I changed it to check for the column "Feed" so I could add several Locations. At first this worked,but I did someething in perfecting it and it now fails after filling the first row of the datagridview (dgvFdMed).I ran a check and the table LotsTab has 8 rows filled. Column 1 & 2 are strings and the database appears they are fine. The added columns have just been created with no value. My plan is to enter the values and then use the data from the grid.
Private Sub sfillGrid(ByVal Loc As String) Dim i As Integer Dim column As DataGridViewColumn
I have 2 Child forms inside a parent. For example, FrmChild1 contains a "Friend Sub" I wish to call.I would like one of the child forms to call that sub from another child form (we will call it FrmChild2. The following code works, but when it's done going through the "For Each", I get a "Invalid Cast"
' THIS CODE IS IN FrmChild1 For Each mFrmChild2 As FrmChild2 In FrmParent.MdiChildren mFrmChild2.GuestRefresh(False) Next
Error after calls are made:"Unable to cast object of type FrmChild1 to type FrmChild2.
I have a series of API calls that are returning J# data types. I have been able to convert most of the data types (Integer, Boolean, Double, Float, etc) just fine.What I need to do now is convert a java.Util.Collection to a VB .NET collection (ArrayList)
Here is my attempt:
Public Function MakeDotNETCollection(ByVal javaCol As java.util.Collection) As Collection Dim dotNetCol As Collection

I have a generic Class I'm using to hold information loaded from a database.I have a method which takes a DataRow as an argument, uses the object's known column name and extracts the data from the DataRow, such that:Dim loadData As T = CType(myDataRow("myColumnName"), T))works as my default assignment in most cases.Unfortunately, due to some horrifying design constraints, some of my columns may be null, and may also be taken from enumerations.This means that when <T> is Nullable(Of SomeEnumeration) the above code does not work because I can't cast 0 directly to SomeEnumeration.Zero.Is there some way to check whether <T> is Nullable(Of [Enum])? Or some way to write a method which allows Integers to be cast to Nullable(Of [Enum])?I feel like I'm forgetting something that would allow me to write one of the other of these, but my weak google-fu is turning up nothing.
EDIT: Okay, thanks to dasblinkenlight's answer below, I can detect when this circumstance is occurring, but what I need to do now is to take a type <T> which I know is Nullable(Of SomeClass), get a type reference to SomeClass and then create a new object of type Nullable(Of SomeClass) and assign that to LoadData.My problem was that I had a lot of difficulty in finding any function which would accept baseType as an actual Type.Parse accepted baseType as a parameter, I knew baseType was an [Enum] type because of dasblinkenlight's code, so I was, in this instance, able to code a solution. It's a solution which is very specific to my problem (i.e., T is Nullable(of SomeEnumeration)), but it's a solution nonetheless.
I have given reference to Microsoft HTML in COM (am using VB 2008)
"Unable to cast object of type 'System.Windows.Forms.HtmlElement' to type 'mshtml.IHTMLElement'."
I want to retrieve all the properties like the class name, html id of every object in the web browser. I am getting the above exception when i try to direct cast it.[code]...
I have a class named State that stores a lot of data regarding the current state (status) of the program (like the user's name, has he saved his work, last color he was using, etc). Before I allow the user to reset the state of the program, I want to backup the entire contents of State in case the user changes his mind and wants to undo things back to the way they were. I'm not looking for a complete undo algorithm, just a way to copy the contents of one object to another object (of the same class).
I have user control which has one button. To handle click event of button I have added following code in usercontrol.
Public Sub ChangeClickHandler(ByVal [Delegate] As EventHandler)
[code]....
Now, I want to handle this click event where I call the this usercontrol. I call the usercontrol through reflection so I get the control in a form of object.
Dim button as object button.ChangeClickHandler(AddressOf mymethod), this line gives me error "'AddressOf' expression cannot be converted to 'Object' because 'Object' is not a delegate type."
