Apr 13, 2009I'm getting an error in .net when trying to declare a Public class on my code behind page.

Public Variable Goe Out Of Scope In Private Sub?
Aug 23, 2009I have a public variable which seems to be going out of scope. I am confused as it has been dimensioned as a public variable: Public xlCell as As Microsoft.Office.Interop.Excel.Range
I originally had all my code in the same module in the same project and it was wrapped within a For/Next Loop (Example 1). I decided to clean up my code and make it more modular (Example 2). All the code is still in the same module in the same project.
Upon doing so, my public variable is not recognized in any of the private subs that I have created. I keep getting the following error: Message="Object reference not set to an instance of an object." When I test the variable using ?IsNothing(xlCell) in the Main Sub I get False in the main sub. this tells me te variable is recognized. However as soon as the Call SelectCaseSub() is triggered, I get a True value for ?IsNothing(xlCell). Why is this? Shouldn't this variable be in scope regardless?

Run PUBLIC SUB From Another Form?
Jun 4, 2009I have a couple of PUBLIC SUB's on my Form1. Is there a way that I can execute them on Form1 through another Form / Button-click? I am using a Dialog1.ShowDialog() for configuring some settings for my application. Now, I have most stuff on my Form1 set / loaded via PUBLIC SUB's (for example THEME SETTINGS, DROPDOWN LIST values and so on), and if I change something in the Dialog1 this Subs need to be executed again ...
Before my explanation gets too complicate, here a sample with a simple SUB:
Asume you have a Form1 with a Button1. On Button1Click a Dialog1.ShowDialog will be executed. In addition you have the following PUBLIC SUB on Form1:
Public Sub ShowMessage()
MessageBox.Show("Hello World!", "Message:", MessageBoxButtons.OK, MessageBoxIcon.Hand)
End Sub
How could I execute this Sub on Form1 from Dialog1 (maybe on a ButtonClick event)?
