Error! ** RESOLVED**

I keep on getting this error on my buddy’s Machine.
It is happening on a third Form that I’m using to enter Data into a Database.
It happens when I click the Close Button. And it only happens when using the Installed Program. If I’m running in VB it works just fine.
It is telling me: System.NullReferenceException:Object reference not set to an instance of an object.
But I don’t really know where to start looking for this error.
Can someone help?
Thanks!

Um, post the code that causes the error?

Sorry!

VB Code:

Dim fMain As frmMain = DirectCast(Me.Owner, frmMain)
        fMain.Label1.Text = lblBalance.Text
        Me.Close()

Don't you have to get new instance of frmMain using 'New' Keyword and also use error handling structure around the code you suspect it cause any nasty error .

No he wants a pointer to his main form i believe.
So in your mainform add this

• Frm.ActiveForm.AddOwnedForm _(Yourformthatsgoingtotkaeownershiphere)
  --------------------------------------------------------------------------------
  Then change this in this form to this
  Dim fMain As frmMain = me.owner
  fMain.Label1.Text = lblBalance.Text
  Me.Close()

That should work.

Pirate!
I don't tink you can use the New keyword when working


I did and it is telling me the same thing!
I don't know why, but all of sudden it started replicating that error when trying to run in Debug mode, whereas before it would not.
it is stoping at

Code:

---

fMain.Label1.Text = lbl.Balance.Text

---

Also I have not yet read into error report structures.
All I know to do is use generic error code.

Code:

---

Try
            Dim fMain As frmMain = DirectCast(Me.Owner, frmMain)
            fMain.Label1.Text = lblBalance.Text
        Catch ex As Exception
            MsgBox(Err.Description)
        End Try
        Me.Close()

---

Thanks for any Help!

No , try somethin like :

VB Code:

'Class level (out side any procedure)
Dim fMain As New frmMain
 
 
'then do this 
 
Try
            fMain = DirectCast(Me.Owner, frmMain)
            fMain.Label1.Text = lblBalance.Text
        Catch ex As Exception
            MsgBox(Err.Description + "___" + Err.Message)
        End Try
        Me.Close()

AFterlife!

I'm missing something; my frmMain's Label needs to be updated when frmDeposit is closed. Therefore it had to have a reference to frmMain.
What is kind off funny is that it was working fine before and now it does not, I can't remember if I made any changes in my project or not. The last thing I did was to add a Module so I'm able to use a Splash Screen, but it was still working.

Anyway, when putting this " Frm.ActiveForm.AddOwnedForm _(Yourformthatsgoingtotkaeownershiphere)" in my main form it is telling me that a Declaration is expected ???
Any Idea

'Put this in the area in which you want to call form 2 from
' and keep the me.ownership in the same way in your other form my bad
Dim form As New the form2 that your going to call from
MyBase.AddOwnedForm(form) ' add it as owned by frmmain
form.ShowDialog()

Oh my god, I feel super stupid now!
I'm calling frmDeposit from two places, one being the Menu and one being a button. What happened was this, in the Menu I have had code similar to what you posted and it is working "I checked it" but my button did not, I had added the button do to a request, and never did think about the way I hade coded my Menu. “High Inelegance here folks!” LOL
UPS!
:blush:
Sometimes them little things will get ja.
Thanks guys!

PS: Pirate! that Err handler did not work, it is telling me that .Message is not a Member. But I will check into it.
Thanks!

oops , it should be like this :

ex.Message
