I have a method called ADD in a class that connects to a database. The database class name is XDB. I also have an object named XXX in it's own separate class with properties.One of the instructions for the Button named ADD click event is:
'Call Add method passing in the XXX object
So this is how I coded:
'declare a variable X as an object instance of XXX

I know it's wrong since it doesn't add the XXX and the form doesn't close but I don't know what I'm doing wrong.
REF: 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.

I need to make an asynchronous call to a method which for the sake of simplicity counts from 1 to 100. If an exception is thrown during the methods counting process, lets say at 50 I need to stop the methods execution, dispose of a few objects and restart it at 51 but have no idea how to go about it.I basically need to raise an event from the method to the main thread and restart the asynchrounous method.
View 3 RepliesIs it possible to read a string and call the method of the same name?For example: I have many buttons and if the user presses the button named A1, I want the Sub AI() to be called. I don't want to do an explicit If-Then for each button. Rather a common ONCLICK method that is called by all buttons and another method (the same name as the name of the button) is called.
Example:
Sub Click(byVal buttonName as string)
call ButtonName ' <<<< Error. ButtonName is string and not a Method.
