Error - In Order To Evaluate An Indexed Property, The Property Must Be Qualified And The Arguments Must Be Explicitly Supplied By The User
Jun 20, 2012
I'm having a few problems converting some code into VB.NET from C#. Most of the translating is done, but I am getting errors when I try to run my code, and I can't figure out what is causing them. Here is the Sub I translated.
Public Sub CreateWidget()
Dim blue As LCDColor
blue.Red = 0
blue.Green = 0
[code]....
The error I receive on this line ("vision.Widgets.CreateWidget(wg1)") reads "In order to evaluate an indexed property, the property must be qualified and the arguments must be explicitly supplied by the user."
I receive a System.Data.SqlClient.SqlException in the following code: Specifically Incorrect syntax near ' In order to evaluate an indexed property, the property must be qualified and the arguments must be explicitly supplied by the user. The exception detail in its entirety is shown below the code.
While running the code I've included below I receive the error "EntityCommandExecutionException was unhandled by user code.I'm then told to look at the inner exception for details...and there I see under Data:"In order to evaluate an indexed property, the property must be qualified and the arguments must be explicitly supplied by the user."And under Inner Exception --> Message:"A transport-level error has occurred when receiving results from the server.[code]
VB code: Public Class InputBox Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim a, b, S, p a = InputBox("Enter length") b = InputBox("Enter width") S = a * b p = a + a + b + b End Sub End Class
In InputBox lines i get this error: Class 'LearningVB.InputBox' cannot be indexed because it has no default property.

I upgraded to ASP.NET MVC 2 Beta and ASP.NET MVC 2 Futures Assembly for Beta and now ToValueProvider() fails with this compile-time error: Interface 'System.Web.Mvc.IValueProvider' cannot be indexed because it has no default property How do I use ModelState.SetModelValue() if not with collection.ToValueProvider()?
I know this is random but is there a way to specify that a property explicitly does not need to be inherited? So you can have two sub classes and one object will have that property and the other doesn't?
I generally use VB.Net for programming but I have been delegated to a VBA project that would benefit from using script control for running script. Here is sample code but errors out on the .Run line of code. I can do this in VB.Net easy but can't get it to work in vba.
ERROR = Wrong number of arguments or invalid property assignment
Option Explicit Dim sc As New ScriptControl Sub RunFunctions()
[code]....
Using the .Eval function from the script control object runs ok in vba but does not run scripts.
Sub SimpleTask() Dim expr As String sc.Language = "VBScript"
Say I wanna bind to dictionary that TKey is string with XAML:<Label DataContext="{MyDictionary}" Content="{Binding Item("OK")}" />Doesn't work.How should I do it?
I am new to classes, and I am new to Visual Basic in general, but I am working on a multi class program. The code seems to be correct, but I am trying on instantiate a class oject with the code:
I am getting a strange error when I try to build my solution. The error occurs when I am calling the oGetHeaderValue function and passing the parameters.
Dim oGetHeaderValue As New clsGetHeaderValue Dim returnString As String returnString = oGetHeaderValue(strInvoiceNumber, strOrderNumber)
The error message is: Class 'clsGetHeaderValue' cannot be indexed because it has no default property.

start with I was given a program by a friend that was created in Excel 2003 with the help of Visual Basic Editor. He said he used Visual Basic 2003, which he is not 100% sure about. Anyways he used CurLine in the program and when I try to open it in Excel 2007 and then open the Visual Basic Editor and run the program I get the following error:Run-time error '-2147418113 (8000ffff)':Could not get the CurLine property. Unexpected call to method or property access.

I am using a user control using vb.net. It include the program to retrieve the values from database while giving the paramers. When I set the property from my main program i am getting an error "Invalid attempt to call Read when reader is closed." When i gone to the online help i got the message as follows "System.InvalidOperationException (.NET Framework 4)The exception that is thrown when a method call is invalid for the object's current state. InvalidOperationException is used in cases when the failure to invoke a method is caused by reasons other than invalid arguments. For example, InvalidOperationException is thrown by IEnumerator.MoveNext if objects of a collection are modified after the enumerator is created, or ResourceSet.GetString if the resource set is closed before the method call is made. If the method invocation failure is due to invalid arguments, then ArgumentException or one of its derived classes, ArgumentNullException or ArgumentOutOfRangeException, should be thrown instead.[code]
Well in my vb project it has started giving me a really weird error underlining all my msgbox codes for some reason

I am getting the error that "Property access must assign to the property or use its value" in the above code.
I want to add a List(Of Book) property to my user control. I defined a Book class and BookCollectionEditor class for CollectionEditor. And also I defined a public property named BookList for my user control. For a custom control it works fine but for user control, the designer does not display my property. On markup I can add a Book item but on designer it gives error: "Type 'System.Web.UI.UserControl' does not have a public property named 'BookList'."Isn't is possible to define a list property for a user control?
<TypeConverter(GetType(ExpandableObjectConverter)), Serializable()> _ Public Class Book Private _name As String Private _author As String
One of my ASP.NET websites makes use of the CultureInfo class to format currency values and normally this works fine. However, some new code is causing some unexpected problems. In the code sample shown below, txtBox1 correctly displays £99.00 while the line that specifies a value for txtBox2 generates the following error,Too many arguments to 'Public ReadOnly Default Property Chars(index As Integer) As Char'.The key difference in the txtBox2 value is that it is derived from a SQL Server database reference using Linq-to-SQL (CurrentUKFees.Print1). The relevant database value is the integer 8 and I was expecting txtBox2 to show £8.00. If I delete the CultureInfo code then txtBox2 correctly shows the value '8' without any currency formatting.[code]
I have some related Properties in a class. Namely, One is a collection of objects and the other is an index to the one that the class instance is looking at. In the designer, I need for the collection to be set prior to the index. I tried to do this manually, but when the file is saved, the Designer goes back and writes over my change. So I need to know how to tell the designer in which order to set the properties.

I've created a custom control in VB.NET on .Net 3.5, in VS2008, which contains a load of custom properties, including RSS feed address, proxy address and proxy port.This control is an RSS ticker, which works really nicely, but doesn't initially run at all, and from stepping through my code, this is because none of my properties are being passed data from the containing form, until after the control has been initialised, and the code behind the control has run. The code (relevant bits) looks as follows:[code]
I have a class where it's problematic to relay on the properties being serialized in alphabetical order at design time.In other words, property Z must be serialized before property A.The problem arises because property property Z clears property A whenever it changes - which happens in InitializeComponent.I work around this problem by setting a FirstTime flag, but that seems messy.
I need a control, like a Label in WPF. But this Label should be always autosized(Width = Height = Auto) - user should not be able to modify it.Also the BorderThinkness should be always = 0. How can I do it in WPF? Is it possible to inherit such a label, in order that the children conserve that property (always AutoSized)?
I get the following string expression provided:"ChildObject.FullName" ...where ChildObject is an instance property on the MyObject1 type.ChildObject has a property named "FullName" and I want to sort a collection of type "MyObject1" based on this child properties "FullName" value.
I can do this all day long on properties directly on MyObject1 but I run into 2 challanges when doing it on a child instance and I can't get all the pieces working. The main 2 challanges are:
MyObject1 has a few different child property types so I can't hardcode the type for ChildObject. The string could be of any type.The sort expression is a String and not a known type.Above the value returned from the last line in the expression (if I run the code outsode the OrderBy method, does provide me the 'FullName' information I need. So the code must be close, but it still does not work.
Any ideas on how I can accomplish this? What I am trying to prevent is hardcoding a series of 'If' blocks on the child's type to then hardcode in its type to the sort or OrderBy method.
