I was wondering if there was a way to get the name of the property my statement is in, like I can get the name of a function in PHP with the magic constant __FUNCTION__. Is there a way to get that property name, and more in general, also for functions and methods?

View 3 RepliesI've got two classes deployed as COM+ components, let's say ClassA and ClassB. ClassA has some public properties. ClassB sets values for those properties and calls a method of ClassA. The method itself does not modify the value of the property. After the call the values of the properties are reset to default values for the corresponding types. This only happens if the called method includes statement ContextUtil.SetComplete(). Once I comment out the statement the values of the properties remain same as they were before the method call, which is what I expect. Do I overlook some basic concept of COM+ objects and their contexts? I would expect the property value to remain the same in any case.
Here's the simplified listing for the code:
Option Strict Off
Option Explicit On
Imports System.EnterpriseServices
<Transaction(TransactionOption.Required)> _
Public Class ClassA
[Code] .....
maybe it's not a method exactly. here's what I'd like to do:
Private _Columns As ArrayList
Public Property Columns() As ArrayList
Get[code]....
which would allow me to conveniently set the property by assigning to it various kinds of collection types... except, I can't do it because apparently the Set method has to take an argument of the type of the property itself... I get the complaint:
'Set' parameter must have the same type as the containing property
is there a way to do this?
If you create a COMClass, I've noticed that the values in the XML Summary tag do not show in the object browser of VB6/VBA when you reference the resulting tlb file. Is there a way to have these values show up?

I have a Class A that inherits from a base class. In the class A i have build some methods/properties.What I want is that some methods/properties from the base class are not visible in the intellisense which makes it easier for a developer. Basically i want to hide all the methods/functions/etc.. which are no use.Is this possible whithout having to use the EditorBrowsableAttribute for every item?The best way would be to tell the class that it must hide all props/methods/functions/etc... and after that i can specify which MUST be visible.

I have pretty much identical methods for other data objects which have been and still are executing just fine.

Interface makes sure a class does have a Method / Property, However is there a way to create an unInterface, making sure that the class does not have a method / property or is there a way to implement something that will unimplement every other implements except for itself?
what i want to do: i've got a class that serves as a storage for information only, so i decided to give it a blank interface IBank, the other classes that share this feature will implement this interface. they should not implement any other interface the use is that when i seek out the interface of a class and realise that its IBank i know that its just a class for info storage.

View 2 RepliesI'm creating a car class. Make and model are properties but both make and model appear to be reserved words in C#. What's the best practice for naming properties/methods when your preferred name is a reserved word?My first instinct is to call the properties CarMake, CarModel (so a convention of ClassNamePropertyName).My mistake, make and model aren't actually reserved words. VS intelliesense and code coloring made it appear so to me at first glance. Though my question does stand for future reference.

Need some help to develop a method/function. No problem if there is no code but I would like to start discussing the best way of doing this even in high level language. First of all would like to provide you with some information. The set that I use here is very small, but the data is on a table in mysql and there will be over a million rows. Its important because if I make a complex loop code, maybe there will be a lot of selects in there.[code]

View 4 RepliesI am experimenting with a transition from my application built in VB6 to vb.net. I know, about time. At the same time, i am making changes and improving upon the original. One area that I am working on is within my employee class. very standard class, nothing fancy. One change I want to make though is allow for an employee to be assigned more than one work location. Employee has (is assigned) Stores. In reading about collections, it appears they are different in .net (as they should be), but I don't know what the sytax changes will be to implement my changes.
View 6 RepliesThis is my first post on this forum, so please excuse me if I'm posting wrong. Anyway, I've been having an issue that I've never seen before and is driving me nut, I have a windows form on which I have placed many textboxes that display information from a MS SQL database. The user can then change these values and hit a "save" button which writes the changes to the database. I also have certain textboxes that with the "on leave" event (after a user enters a possible new value) trigger a method that recalculates some of the other fields based on the new information. Hopefully that all makes sense.
So the problem is, when I run through this "recalc" method the first time around, it doesn't update those textboxes that it's supposed to. However, when I put a breakpoint in and debug through it, the debugger shows it putting in the correct values into the textboxes. It's just as soon as the method is done, it puts them back to blank, or whatever they were before
