View 16 RepliesI have published application before and they all (3 setup files) work fine. The problem is I don't know anymore how I exactly did it. Now I am trying to publish another form which has a connection to my sql database. The publishing goes fine: publishing folder is: C:Movie-databaseApplication 4 and installation folder is the same, and I therefore leave it empty. Application is available only online. But when I execute the published setup.exe I get two windows with no info about the error: see attachment.

First I found that you can catch it and log it inside a catch, but this doesn't send an email. Then I found out about using the Error Signal class. That worked, however what wasn't apparent from reading, is that it treats the error like normal, so when I signal the error it goes to the custom error page still, I don't want that to happen. What I want to do is catch that error, log it, send the email, but stay on the page the error happened so I can provide special feedback. I do not want it go to the custom error page.
This is what I have and it redirects me to the custom error page.
Try
smtpClient.Send(mailMessage)
Catch smtpEx As SmtpException
errorSignal.FromCurrentContext().Raise(smtpEx)
Catch ex As Exception

I have created an application which listens for strings being sent to my pc from a remote unit. I now need to add the function of sending strings back to the remote unit on a button press. I've searched for ages to find a solution but I'm not knowledgeable enough yet with vb.net to solve this solution.
I'm getting the error with the line opensock2 = New IO.StreamWriter(client.GetStream) saying its not connected. So I seem to need to pass the connection from the background worker to the button click, or have it somewhere else in the code to make it accessible. [Code]
VS 2008, .NET 2, Win XP I need to design some kind of Error reporting. I got the Idea for the design and code but before i begin to code it I need to decide where to put it:
--1. Inside my app in Shared Sub- Can I call it from Another App (No), Can I call it if app crash sudenly?
--2. Inside a separate dll- I think that this is the way to go (i can use it inside this and another app, but can I call it if my app crash sudenly?
--3. Create another "app" to do that- Maybe to complicated for what needs to be done
I need to use that also in another apps so I think that 1. is out and 2. is my preferably solution.
If an error occurs in my application, I'd like an email to be silently sent to me with the error description (as long as the internet connection is established).
I know how to send emails in VB.Net, but I wonder what is the best way to get this done.
Is this something that should be done in a module? I could use some advice on the subject before I start coding.
Although im using this simple logic the image that is being displayed on the remote machine the one that i send is not the same as you can see. In fact 90% is missing! The Image Size is 256KB JPG

View 6 RepliesI'm using a dll in my program, it works fine. But when I publish and try to run on another machine, it says the dll is missing.Am I right in saying that I need to add it to my references, with the Add button on the references page? When I do that, it says it's not a valid assembly or com component.
How do I fix this? My level of knowledge is very low, especially with dll's.

I have written a fairly basic application. It reads txt files, loads a SQL, and outputs to text files. The application compiles and publishes without an error. The app works perfectly on my PC. I can not get it to work on any other PC. Application will install without an error but when I try to launch the app, nothing happens. Running out of ideas to try and hoping someone may have some tips or tricks to try and see what is going on that I have not tried.I am running Windows 7 Pro - 64 with Visual Studio 2008. The only references are for .net 2.0 and ADODB.DLL. I have setup the app to include all references as local copy to true.
I have tried installs on Windows 7 Pro, Windows Server 2000, Windows Server 2003, Windows XP Pro, and Windows Vista. All install without error. Have tried installed as user with admin rights and the PC's primary admin account. When you launch the app, there are no messages in all OS except Windows 7. It will basically Flash a message about checking for compatability and run you through a wizard to see if running as XP or Vista works and it doesn't.
I have an XML file in Bin/Debug that I am referencing using the code below. It works fine in testing, but when i publish i get an error seen below the code.

m_xmld = New XmlDocument()
