Linq And Generics. Using GetValue Inside A Query?
Dec 28, 2010I'm triying to make a function that add a 'where' clause to a query based in a property and a value. This is a very simplefied version of my function.
Private Function simplified(ByVal query As IQueryable(Of T), ByVal PValue As Long, ByVal p As PropertyInfo) As ObjectQuery(Of T)
query = query.Where(Function(c) DirectCast(p.GetValue(c, Nothing), Long) = PValue)
Dim t = query.ToList 'this line is only for testing, and here is the error raise[code].....
The error message is: LINQ to Entities does not recognize the method 'System.Object CompareObjectEqual(System.Object, System.Object, Boolean)' method, and this method cannot be translated into a store expression.Looks like a can't use GetValue inside a linq query.
Private Function simplified2(ByVal query As IQueryable(Of T))
query = From q In query

.net - SetValue/GetValue Versus Directly Accessing Array Via Arguments?
Jun 4, 2012I have an array which originally was a Variant array in VB6. Example code in VB6:
ListBoxDrawings.List(X1, Y1) = myArray(X2, Y2)
myArray(A, B) = ListBoxDrawings.List(I, C)
After running it through ArtinSoft's VBUC, its values are handled using GetValue & SetValue.Example code in VB.NET: (ignore conversion to ListView)
ListViewDrawings.Items(X1).SubItems(Y1).Text = CStr(myArray.GetValue(X2, Y2))
myArray.SetValue(ListViewDrawings.Items(I).SubItems(C).Text, A, B)
Since VB.NET doesn't do Variants, I figured out that the array should be typed as a 2D String Array. It seems like there's no reason to use GetValue/SetValue, as the former returns an Object and the latter takes one. This means that I'd have to cast the returned object as a String (Cstr) if I wanted to assign it to a variable, which seems like a pointless extra step that might introduce errors. Also, since the method has lots of overloads, the code might not be as clear. Is there any advantage to using SetValue / GetValue, or should I just consider that an artifact of VBUC converting a Variant, and access the array directly like the original code did?
VB.NET without Get/Set methods:
ListViewDrawings.Items(X1).SubItems(Y1).Text = myArray(X2, Y2)
myArray(A, B) = ListViewDrawings.Items(I).SubItems(C).Text
.net - Strongly Cast A Reflection .GetValue() Object To A Generic DbSet?
Apr 10, 2012I'm using EF 4.3.1 in VS 2010 (.Net 4.0) to load a number of reference tables from a database in order to bind them to controls in a WinForms app.At form load, I'm pre-fetching the data so that it's stored locally, and I'm creating a dictionary of BindingSource objects that I can use to bind the local data to the controls.The intent is to minimize the impact of the EF's self validation on a cold query in order to load forms faster and improve UI responsiveness.I've written code to create and fetch the BindingSource object for a given DbSet collection as follows:
Private _dictBindings As New Dictionary(Of String, BindingSource)
Private Sub ValidateBinding(Of T As Class)(ByRef DbCollection As DbSet(Of T))
Dim strClassName As String = DbCollection.[GetType]().GetGenericArguments(0).Name
If Not _dictBindings.ContainsKey(strClassName) Then[code].....
However, I'd like to call ValidateBinding on all DbSet collections in the Model on startup, and I'd like to use reflection to iterate through the available collections in the context because we're currently loading 66 tables and could add more later.I've written the following code:
For Each propSet As PropertyInfo In Db.GetType.GetProperties(BindingFlags.Instance Or BindingFlags.Public).Where(Function(P) P.PropertyType.IsGenericType)
ValidateBinding(propSet.GetValue(Db, Nothing))
Next
but it won't work as propSet.GetValue() returns an Object instead of DbSet(of T).I also can't cast the object to a DbSet of the appropriate type, even though I know the type through reflection.I don't have access to the C# Dynamic type,and I know it's a pain to mix generics with reflection, but is there a solution for which I can pass in a reflected DbSet to my functions?Perhaps something using Method.Invoke?
DataGridViewComboBoxCell Not Correctly Displaying Objects Returned By GetValue Function
Jul 14, 2009I have a Class MessageIndex which holds an integer. I have a custom DataGridViewComboBoxCell which has a MessageIndex variable. If the MessageIndex is not set, the cell acts as a normal DataGridViewComboBoxCell; if the MessageIndex is set, then the GetValue and SetValue methods of the DataGridViewComboBoxCell are overridden so as to return the value of the object from its DataSource at the index of the integer stored in the MessageIndex.
As far as I can tell from stepping through the code, that actually works fine. The object returned by the GetValue function is fetched from the DataSource, based on the integer stored in the MessageIndex.
The problem is that when the DataGridView is displayed, all of the cells are blank. The values of the cells can then be set using the ComboBox dropdown, which appears to work fine.
But why are the initial selections not being displayed? As I say, as far as I can tell, the correct information is being retrieved by the GetValue function of the DataGridViewComboBoxCells when the form is initially displayed. It's just not ending up on the screen.
Listbox To Show .01 To 5.0

View 2 RepliesListbox Strings Don't Show Up?
Apr 29, 2012I am doing this assignment on a Math tutor program and I am stuck at one point.First off the listbox needs to show the equations for the number entered between 0 and 12 example:
1+1=2
1+2=3
1+3=4
1+4=51+5=6[code].....
I don't understand how to get that information into a list box.I am also stuck in an infinite loop somehow i think because nothing shows up at all in the listbox and the number the user enters should at least be there. I am assuming the code should be more like
lstbox.items.add(decNumEntered("+1 =")

Option Explicit On[code]............

View 5 RepliesGet A Listbox To Show Information On A Different Form On The Same Application
Jun 7, 2011Im suppose to make an application that tracks electric motors in a manufacturing plant. It needs to have
MotorID:Five-digit string, such as "02340"
Description:String
RPM: Integer, values in the range of 10 to 10000
[Code]......
I was thinking about doing this part in radiobuttons
The application should be able to store at least 10 motor class objects in an array, create an input form in the application that allow users to input new motor records to be added to the array and create another form that displays all the motors in the array in a list box. This is what I got so far, I know its not much, but whats really puzzling me is how am I suppose to show all the data in the listbox in the second form.
This is whatI got for the first form
Public Class Form1
Dim range As Integer = 0
Dim voltage As Integer = 0
[Code]....
and the second form I really dont know where to even start on that one.
