The Error I get is "Couldnt show any because: Object reference not set to an instance of an object"While on the development machine it works.Both running Win7, I inclluded all sql files as stated on the deployment instruction for datafile and sql-ce dll's from the msdn.The datafile is fine and connection is good, becuase a "cmd.ExecuteNonQuery()" runs without problems.
Public Sub LoadFolders()
Dim ds As New DataSet
Dim da As SqlCeDataAdapter = New SqlCeDataAdapter()

We have a huge windows application with poor exception handling. The application throw object reference error from lot of places and the system error message is showing to users as it is using message boxes.
I am looking for a simple solution which can be used to replace this message to something user friendly for the entire application

I updated from VB2010 Express and Win7(x64) from VB2008 Standard and Win7(x86) and have been tweaking a programme and some user controls I have been using for some years. In the last three days only whenever I open the programme and run it, I get the error message box "Object Reference not set to an insatnce of an object"" three or four times. The programme then runs correctly. If I stop and restart the programme, the error message not reappear. If I then edit code and rerun (or save) the programme, the error message reappears. The error messages do not appear if I run the programme from the EXE file pinned to my taskbar
I have been unable to trap the error message to find out on the stack a clue to the line in the programme that is causing the problem. I do not add controls at runtime and all have been added to the designer at design time.

I have been working on a program on my old computer. Now, I have gotten a new computer and would like to continue to work on it there. The program is not yet finished. I would like to copy my program to my new computer. How can I do this? I tried copying the folder from my old computer to my new one and it opened the project, but I could not edit it as there was no permission given to edit it. It shows it as a read-only.

I have developing a program on one computer and when I try to move it to another computer running vb2008 express, I always get an error message saying "the project file (directory path, project name.vbjproj) has been moved, renamed or is not on your computer." The files etc. are in the same folders as other projects that run properly. Can't figure out how to correct the path etc. or figure out why the message as the files are where they should be.Cancel the question. I found my problem and it was me that caused it.

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

I am having trouble opening my vb.net 2005 project from a backed up copy on a hard drive. The original files are on my old XP computer which I no longer have access to. I am trying to open the project in vb.net 2010 on Win7. I have converted the project to vb.net 2010 and when I open the file, nothing shows up, when I try to open them, it tells me the form isn't found in the project directory because it's been moved or deleted. I know that the software on the hard drive didn't back up .exe files, I'm not sure if it did back up other kinds of files. I don't want to restart the project because I've spent over a year on it and have written over 3000 lines of code on it.

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.

I am using this exact code on another form in the same project without an issue, just with a different data source. Any ideas?
EDIT: Never mind, seems like it was a stupid naming scheme and VS was adding a bindingsource with a different name than I wanted.
