LINQ To Entities Does Not Recognize The Method [Type] GetValue[Type]?
Mar 14, 2012I've a simple class like this:
Public Class CalculationParameter{
public Long TariffId{get;set;}
}
In a workflow activity, I've an Assign like this:
(From tariffDetail In db.Context.TariffDetails
Where tariffDetial.TariffId = calculationParameter.TariffId).FirstOrDefault()
Dto is passed to Activity as an Input Argument.It raise following error and I'm wondering how to assign Id.LINQ to Entities does not recognize the method 'Int64
GetValue[Int64](System.Activities.LocationReference)' method, and this method cannot be translated into a store expression.
How can I assign the calculationParameter.TariffId to tariffDetial.TariffId?!
UPDATE:Screen shot attached shows that how I'm trying to assign calculationParameter.TariffId to tariffDetail.TariffId (car.Id = Dto.Id) and the query result should assign to CurrentTrafficDetail object.

Web Method Giving A HTTP401 Not Authorized Error
May 10, 2012I use web methods in a couple of places in the intranet site im working on and they work fine, however one page is constantly throwing a HTTP 401 error every time I try access the web method.
Im not sure how to aproach this issue, I have tried commenting everything out of the web method, and still get the 401 error, even a basic connect to the database just doing SELECT 1 does not show up when I watch the DB with profiler.
My web.config is the same for all pages in the intranet and I cannot see any differences in my ASP.Net page compared to pages where web methods work.[code]...
Method Parameters Have Incorrect Values When Using RowTest
Apr 6, 2010I have the following test method (VB.NET)
<RowTest()> _
<Row(1, 2, 3)> _
Public Sub AddMultipleNumbers(ByVal number1 As Integer, ByVal number2 As Integer, ByVal result As Integer)
Dim dvbc As VbClass = New VbClass()
Dim actual As Integer = dvbc.Add(number1, number2)
Assert.That(actual, [Is].SameAs(result))
End Sub
My problem is that when the test runs, using TestDriven.Net, the three method parameters are 0 and not the values I am expecting. I have referenced the NUnit.Framework (v.2.5.3.9345) anf the NUnitExtension.RowTest (v.1.2.3.0).

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.

.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.

VS 2005 - How To Use SetSelectedRowCore Method Of DGV

Internet searches point to the use of the SetSelectedRowCore method of the DGV, but this is a "Protected" method.
