I didn't code for a complete year. Don't ask me why. well I guess I lost 90% of my vb skills, I hope they'll get back eventually.i'm writing a console program, but it closes after a second it opens.I want it open all the time.

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?
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?
I have the following code to close a form which is a child. The problem is that when it closes, it closes the MDI parent too.

I was thinking of adding a simple bandwidth monitor to a console application and I was wondering if it would be possible to keep a line in the console window visible at all times. I could set something up manually to pass new console output into a method that would get the contents of the console, clear the console, add the bandwidth data on the first row, then rewrite each line of previous information back to the console, etc.. but that seems like a really hacky way to go about it, and I'd be limited to the amount of rows visible at once in the console window (no scrolling).

View 2 RepliesI am working on a program and for some reason when I run it as an executable outside of debug mode, if I run the main subroutine of the program, the process remains in memory after being closed. Even though the form is closed/gone, it will be in the process list and I have to ctl-alt-del to remove it. If I exit right after opening the form without doing anything, it closes like normal. I am closing and disposing everything I can think of, and I've never had this problem before. This is how I am exiting, but the problem also occurs if the user "X's" out.
Me.Close()

I have a couple web file requests in my program, which is the only thing out of the ordinary (code-wise) for me, don't know if those are the root of the problem. I can't imagine this is the first time this has happened to anyone, but I couldn't find anything helpful with my search terms. Any ideas/common solutions? I can post sections of my code if it will help, but the whole thing is pretty long and I couldn't narrow down any potential problem areas.

Obviously I could just handle the exception and ignore it but I'm sure there must be a more proper way of doing it. One thing I am thinking of trying is using the BeginAcceptTcpClient and EndAcceptTcpClient methods but for one thing I'm not sure if that will actually help and for another thing the Begin and End versions of methods have always confused me in the past... I mean for a start how do you know when to call End?
I figured this must be a fairly common problem but searching the forum only turned up one result and it wasnt any use. I'll keep playing around and trawling google but just wondered if anyone had come across this before?

VS 2008 Finding the reason a form is Closing
View 1 RepliesI have a modal form that does double duty.When a user wants to add a new object to a database, I open the form blank and they fill it out. When the form closes, all of the data is passed back to my main form and is used to create the new object in the database.When a user wants to edit an existing object, I open the form and pre-populate all of the fields with the object's data.I'm running checks on the form as they edit the fields, only enabling the "OK" button (which will update the database) if the form has actually been changed. If they make a change and then undo it, the "OK" button is reset to Enabled = False.At the bottom of the form are a ComboBox, two buttons and a ListBox. The intent is to allow the user to select an item from the ComboBox and "Add" ("Add" button) to the ListBox, or select an item in the ListBox and "Remove" ("Remove" button) it FROM the ListBox.
This function works fine when the form is loaded blank.When the form is loaded with data, however, (and in the testing I've done, the ListBox has no items in it to start, which is valid), adding an item from the ComboBox to the ListBox causes the Modal form to close with a DialogResult of Cancel.I've tried to trace the source of this issue, but stepping through each line in debug mode gives me no clue as to why this is happening.I COULD remove all of the checks and update the form each time the user presses "OK" (in the case of no changes, the database data would be overwritten with the same data), but that seems kludgy and less elegant. Plus, I'd like this logic to work.

I was wondering if you should dispose undisposed resources before closing your application. Maybe it's not necessary to do this because closing your application automatically takes care of this.
