Object Reference Error "Object Reference Not Set To An Instance Of An Object"?

Aug 26, 2011

I have this bit of code

Private Sub SpellChkMenuItem_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles SpellChkMenuItem.Click
Dim activeRichTextBox = TryCast(Me.ActiveControl, RichTextBox)
'clsFS.CheckSpelling(activeRichTextBox)[code]....

When I am in the rtb and click on spell check button it tells me the error "Object reference not set to an instance of an object." On this line

SpellChecker.Text = activeRichTextBox.Text

But it is suppose to be getting the focused rtb correct? So why is it not referenced

Error - Reference To A Non-shared Member Requires An Object Reference

Dec 7, 2010

I am opening frmB (variable for FormB - the actual form) from frmA. From btn1 I open frmB like this:

frmB = New FormB()
frmB.Show()

From btn2 (frmB is already open) I bring frmB to the front from behind frmA:

FormB.Show()
FormB.BringToFront().

No problem so far. Now I need to pass an arg to frmB. This is where I am having the problem.

from btn1 (in frmA) I do this:

frmB = New FormB(myArg) '--pass myArg to constructor of FormB -- no problem here
frmB.Show()

then from btn2 -- this is where I have the problem

FormB.Show()
FormB.BringToFront()

I tried placing myArg in FormB.Show(myArg) but that did not fix the problem. What is the correct way to pass myArg to FormB (frmB) in this scenario? Do I need to share FormB or frmB? How do I do this? "frmB" is frmA level variable.
