Form1 is a mdi container. It has a bunch of forms that can load inside of it as mdi children. If I close each open form inside the form1, and then click the red X at the top right, application exits fine.If I click the red X without closing the forms inside I get: An unhandled exception of type 'System.CannotUnloadAppDomainException' occurred in mscorlib.dll
Additional information: Error while unloading appdomain. (Exception from HRESULT: 0x80131015) However I can break from it. How do I get the application to not show that error? What must I do to fix those inside forms or close when the red x is clicked?

The above code is what I used in VB6 to close all forms associated with my programs before my program closed. I have been searching for information on how to make sure all forms are closed when closing a VB2008 program.
I have seen info on using the Project Property Shutdown mode When startup form closes and I currently have this set.
Is this all that is really necessary? Will the garbage disposal close everything else to free up RAM?
Also, if I have several forms open and want to close all from the main form without closing each one individually, what is the best approach? Is there a collection like in VB6, go through the collection, compare it to the name of the main form and close it if it is not the main form?

I am using My.Computer.Network.UploadFile(arg1,arg2,username,pass) & sometimes it returns an error to me about not being logged in?I keep using IE & such to visit the ftp'd pages & even login & logoff the ftp site server at times, but seemingly randomly it will fail, even if I use try catch statement, it seems to keep wanting to fail till i go back to IE & go to a webpage on the server or log back in to the account management through IE.
Should it not be authenticating & working correctly each & every time regardless unless the server can't be reached? Why is it wanting to fail SOMETIMES when closing these webpages/logging out on IE only, why is this seeming to have any bearing on this failing in VB.

After roughly 250 iterations of about 5-6 WebRequest per iteration, the app hangs and starts hitting the WebException "The remote name could not be resolved: 'hostnamehere' ". WebPages also don't load through my browser when this happens, I have to close the app for my internet to work again. This app is multithreaded and I was testing with 100 threads (in a threadpool, MaxThreadCount set to 20, addressof the sub which performs the WebRequests). A test with 20 threads yielded identical results - Same WebException also right around 250 iterations processing the same sub. I have tried setting the ConnectionLimit of the request to the thread count with no luck.

The NotifyIcon control is in my frmMain. However, when I run my program I get mulitple instances of the Notify Icon being displayed. I even get two frmMains getting launched if I try clicking the other tray icon that has been made. I'm guessing this has to do with the New instance.If that's the problem, is there a way I can move the notifyicon control to some completely separate class?
I'm currently coding a multi-form project that requires a NotifyIcon. The first form is the Login form which then opens a 'logging-in' form and then finally another form (they're all opened using FormName.ShowDialog() and they hide themself before opening the next form).Login Form -> Logging In Form -> Final Form.When the final form is opened, the NotifyIcon's visible property is set to true and it appears in the tasktray like normal. But when I use Me.Hide on the final form, the NotifyIcon disappears with the form.Any ideas about what is going on? The program still runs in the background despite no forms are visible (which is how it's intended to be) but without a NotifyIcon, there's no way of making the forms appear again.

I created a simple service that does some inventory and records the data to a MySQL server. The service starts just fine when told to from the services administration panel. However, it will not on computer bootup. I get the famous error.
The InventoryService service failed to start due to the following error:The service did not respond to the start or control request in a timely fashion. I've read that logs can be a problem, so I disabled the autolog...but that didn't solve any problems. I believe it has something to do with the user not already being logged in and attempting to connect to a remote database. So, I added a function to check for internet connectivity before executing any inventory methods or SQL queries. This did not fix it either.
EDIT: I also am receiving the following error in the administrative logs. I create the service dependant upon the Tcpip service, but it still fails.A timeout was reached (30000 milliseconds) while waiting for the InventoryService service to connect.
