This might be a dumb question, but is it possible to call the beginning of a class from a different part of the same class?Here's the scenario... I have a class which has several subs in it. One of the last subs features a conditional statement. If that conditional statement is true, then I want the class code to be executed again, from the very beginning of that class.

just because you can do something, it doesn't mean it's good programming practice. To that end, I have a question about calling a public property from inside the class in which the said property resides. It seems that I can call it, similar to a sub, using me.property, but is this good programming practice?

Base class has one field to hold numeric balance value. With 2 methods that accept arguments for adding and subtracting the new input calculating new balance. Sub class has four fields dates, transaction, memo and amount.I have a deposit form, and withdraw form. Each time one transaction is entered it creates an object with sub class fields, then adds to the account collection. My problem is not understanding how to call the deposit/withdraw method and pass the current transaction amount back to the base class to alculate the new balance. Does anyone have any links to information/tutorials on how to perform something like this? As you can see with my code I have tried various different approaches without any success.

I want to call a method on an object I've written in a VB.net class library within the VBScript event handler.Is it possible to do without registering the .dll or using the GAC, but maybe just referring to the path of the DLL.Or could the object be served by another .net program which is running at the same time?

I have an application written in .NET 4.0 that i compile into a DLL file. I want to be able to use this DLL file in a Windows Forms .NET 2.0 application. I don't need the application to really interact much, except just passing a couple string values to the 4.0 DLL. The DLL is pretty much a bunch of Windows which i converted to UserControls and i just need to be able to reference them to display the UserControls from the 2.0 application without having to use a different exe and having to package them separately.
What is the best way to do this? Because when i try to add the reference to the DLL to the 2.0 application, it gives me and error saying the DLL is built in a newer version of .NET so i can't do it that way. Is this where a COM object would come in?

View 7 RepliesREF: http:[url].....The above reference is where I got the code below.This code adds buttons to Form1. When a button is clicked a messagebox appears stating what button was clicked. I want to have the ClickHandler fill a RichTextBox on Form1 (I added a RTB to Form1). My problem is I can't do a Dim xForm As New Form1 to fill the RTB from the ButtonArray Class. I can place my file's text in a MessageBox so I know the code I added is correct. I also tried placing a Property method on Form1 and using a Accessor to fill the RTB, however it also requires Dim xForm As New Form1. How can I get my data from files to the RichTextBox on Form1 from the ClickHandler in the ButtonArray Class? See ButtonArray Class Below.
