I got an out of memory exception in a photo editor thingy i was making in vb.net. The bitmap image is constantly changing, and I always Dispose() of it after it has been sent off to the other bitmap. Is it being stored in a temp folder and using up all my space on the computer, or what? It always bugs after about 8 bitmaps have been drawn.

As you can see i am wanting to use linq to remove duplicates, and also because i want to use the union and except statments elsewhere.
The above is fine if the filesize is about 150mb but with 250mb it throws a out of memory unhandled exception, on 'sWriter.Writeline(sline).
I am thinking this would need to be inside the loop, but cant work out how include my linq statement also.

I am inheriting my class from a form that has a handler for FormClosing (it's overridable so I can override it and do MsgBox("Ha") there before calling the base method). In my Shared Sub New() I have:
' Add the event handler for handling UI thread exceptions to the event.
AddHandler Application.ThreadException, AddressOf Application_ThreadException
' Add the event handler for handling non-UI thread exceptions to the event.
AddHandler AppDomain.CurrentDomain.UnhandledException, AddressOf CurrentDomain_UnhandledException
'For Console applications you should use the System.AppDomain.UnhandledException event
AddHandler Thread.GetDomain().UnhandledException, AddressOf CurrentDomain_UnhandledException
If I throw an exception in my form outside of a try/catch I am noticing two different behaviors: If I am using the VS debugger I get an unhandled exception and it seems that my unhandled exception handler is called. The formClosing event handler does not seem to be called. If I am NOT using the VS debugger then the FormClosing Handler is being called but the Unhandled Exception handler isn't called. Ideally I would like (in both cases) to have the Unhandled Exception to be called and then the FormClosing event handler to be called.

View 2 RepliesI am wondering how I would get the information on what errors get processed by the application.unhandledexception. I already handle the event and gather the information, but I am unsure how or what the best way to get that information to me (the developer).
So far I have vdialog that asks the user if he/she wants to send the error to me, kind of like when an error occurs in Windows XP and a dialog asks the user if they would like to send information about the error to microsoft. I am unsure what to do when the user clicks "Send".
I have thought about emailing to me, but I don't really want to put my email address as the from, because I might change it or its password in the future, thus breaking its usability.
I cannot yet do an anonymous FTP upload, because my website only allows one FTP user, and that is used only to update the website.
I also have thought about using the user's default email program, but that will not work in most cases of people who rely on web mail.

I am writing a program that creates a file and attaches it to an email. I use a loop to create the attachment, send the email and then do it again with different information in the attachment. This works well for one tim through the loop, but on the second time through I get an error when I try to open the file for output to create the new version of the file. I get an unhandled exception of "The process cannot access the file 'c:ProjectArticles1Article.txt' because it is being used by another process.". How can I release the file from being used once the email has been sent?
