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."
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]
View 2 RepliesI 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'm having some very weird issues with interfaces right now.
I have a very simple setup. In one of my class, I have a Property implementing a Property from an Interface.
In my class it's like:
Private _oForm As IForm
Public Property Form As IForm Implements IContainer.Form
Set(value As IForm)

I have like dozens of interfaces like this working throughout my project and I can't believe this simple one can't work!
When viewing a dates Kind property in the watch windows the value "unspecified" will always be return regardless of the actual value.I'm kinda guessing this could be more of a general bug relating to the quick watch window evaluating the shared "Date.Kind" property rather than the specific date instances property.
View 4 RepliesOne 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]
View 2 RepliesFirst, I am making the assumption that anything you can do in "Attribute Syntax" (AS), you can do in "Property Element Syntax" (PES), but not vice-versa. That is the reason I intend on coding completely in PES if possible. I have encountered quirks though.The first issue is regarding AS "x:Name" or PES "<FrameworkElement.Name>": If I use PES, I must make sure it is the last element, otherwise any PES below it will error on build; eg "Value of type 'System.Windows.ResourceDictionary' cannot be converted to 'Namespace.ClassName'."
A problem encountered intermixing AS and PES: Set "x:Name" and "MinWidth" as AS. Set "Title" as PES.

I think it's substituable for just Dim, Public or others. What is merit by using structure, property ??
View 1 RepliesI 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.
View 2 RepliesI 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?

View 3 RepliesIn an ASP.NET 3.5 VB web app, I successfully manage to cache an object containing several personal details such as name, address, etc. One of the items is CreditNum which I'd like to change in the cache on the fly. Is there a way to access this directly in the cache or do I have to destroy and rebuild the whole object just to change the value of objMemberDetails.CreditNum?The cache is set using:

Dim userID As String = HttpContext.Current.User.Identity.Name
HttpContext.Current.Cache(key & "_" & userID) = value

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.
