Hello,
I am not sure if this is allowed or not – if this post is against any Rules i apologize in advance and this post can be removed.
I am in the process of creating a open-source project to track the Psychological Mood of a person, this application will be used by people visiting psychologists.
Target Audience
People that are currently in therapy or want to keep track of mood changes. The program is based on CBT.
Aims
To provide to the end-user the tools for him to be able to monitor his mood.
To provide to the therapist additional information for the client through the automatic generation of graphs.
To reduce the international suicide rate.
To make this application available for everyone to use.
We are looking for some volunteers to help with Coding of the Project.
The Project has been seperated into three parts for easier management.
The Desktop Application is coded in VB.NET and using an ORM called nHibernate.
Project URL: http://moodtracker.codeplex.com
The Web-Based Application will be coded in C# and use MSSQL as the Database.
Project URL: http://webmoodtracker.codeplex.com/
The iPhone Application.
Project URL: http://iphonemoodtracker.codeplex.com/
We're aiming to develop a feature-rich Psychological Mood Tracker to help the end-users as much as we can.
If anyone is interested please feel to apply to the CodePlex Project Page.
Thank you in advance.
Constantinos

Not against the rules but probably not the correct forum.

Hello gurus,
I hope someone is around these days, and to everyone who sees this I want to wish a Merry Christmas and a Happy Holiday!
But "let's get down to business": In my application I have to update the form from a different thread, which I do with the following code:
Private Sub UpdateProgress(ByVal value As Integer, ByVal labelText As String)
If StatusStrip.InvokeRequired Then
StatusStrip.Invoke(ProgressUpdater, New Object() {value, labelText}) <---- ERROR
Else
If value > StatusProgressMain.Maximum Then value = 100
StatusProgressMain.Value = value
StatusLabelMain.Text = String.Format("{0} Records", mDVdata.Count)
End If
End SubUnfortunately I run into 'NULL referece exception' when invoking the StatusStrip although neither the value nor the labeltext variables are NULL. Do I probably overlook something like a plain syntax error?
Thank you for reviewing and any hint!
Mick
EDIT / RESOLUTION:
The exception turned out to be thrown in a different part of the procedure, the 'Else' clause: The mDVdata datatable wasn't properly declared!

Which reference gives the exception?

Hi Richard,
the reference is "Object reference not set to an instance of an object". Would that probably mean that I have to declare another instance of ProgressUpdater? I suppose there's already one instantiated by
Private Delegate Sub AsyncDelegate(ByVal value As Integer, ByVal labelText As String)
Private ProgressUpdater As New AsyncDelegate(AddressOf UpdateProgress) right at the start of the form class?
Thanks again
Mick

Yes but which reference? You have an object reference in your code that has not been initialised so you need to look into your code (maybe with the debugger) to find out which it is and why it is still null.

Thank you, Richard - I put the resolution into the main messages edit. And: You're absolutely right  !
Merry Christmas again!

I suspect that the ProgressUpdater delegate might not have been initialized.
|
|
|
|

Hi Shameel,
I have these two lines right at the beginning of the class:
Private Delegate Sub AsyncDelegate(ByVal value As Integer, ByVal labelText As String)
Private ProgressUpdater As New AsyncDelegate(AddressOf UpdateProgress) Would that be sufficient?
|
|

Michael Schäuble wrote: Would that be sufficient?
Should be.
Can you check which element of your code is throwing the null reference exception? If your StatusStrip is itself null, then your designer generated code might be screwed up.
|
|
|
|
|
But in that case the If-clause would throw the exception, wouldn't it?

Yes, it usually would. But it is also possible that the Invoked method is throwing the error and since it does not have a Try Catch block, it is being pushed backed up the stack. Add Try Catch and some custom logging to find out where the problem exactly is.

Thank's for your help, Shameel. I found it out and put the answer into the main message as an edit.
Merry Christmas again!

You're welcome. As I have mentioned in my other post, since there is no Try Catch block, the exception is pushed up the stack and is handled by the called method at the Invoke call.

You already posted this question in Quick Answers.
It's considered a bad habit to post in more than one forum, mainly because readers can't see what answers already have been given (in the other forum).
Please don't do this again.
Cheers

This is going to hurt, but it's for your own good.
First off all, VB6 is deprecated. It's no longer supperted by Microsoft. It's kicked the bucket, it's shuffled off it's mortal coil, run down the curtain and joined the bleedin' choir invisibile!!
You can use the Microsoft Interop Forms Toolkit[^] to migrate at your own pace. You can extend VB6 applications using .NET code (means you can write new code in .NET and call it from VB6), giving you access to all kinds of .NET goodies like the WebBrowser component, the PropertyGrid control and the EntLib.
Second, you'll need to use something else than a SaaS provider, as they always require internet-access.
Third, you specified what technologies you're interested in, not what you are trying to achieve. You get more usefull replies if you state what you're trying to achieve. Like, if you're looking for longitude and latitude for a specific country, we could advise an alternative like GeoNames[^].
I bet you need maps in a local database.
