VS 2008 Closing All Forms When Program Closes Vs. Closing All But Main Form
Jun 4, 2010Dim frm As Form
For Each frm In Forms
Set frm = Nothing
Next frm
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?
Closing Application Via X Button Without Closing Forms Inside Mdiparent Causes Exception Error
May 3, 2010Form1 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?

Apr 3, 2011I'm having trouble using the HasChanges method.I'm trying to get a message box to show if a user hits the edit button, makes a change, then hits the close button without hitting the save button first. From what I understand, the HasChanges(DataRowState.Modified) statement should work.In reality, when I hit the edit button, make a change to a field (zip for example), then hit the close, it just closes without showing the messagebox.Here's my code so far...

View 2 RepliesVS 2008 Process Not Closing With Form?
Apr 29, 2010I 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()
Application.Exit()
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.

Feb 5, 2010Is there a way to prevent the form closing event from executing if validation fails on a control? If validation on a control fails this stops the form from closing, but the closing event still executes. Scenario is user has focus in a text box, tries to close the form. Validation fails, but closing event is fired. I'm not sure how I can abort that event.

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?

View 1 RepliesVS 2008 Modal Form Closing Unexpectedly
Dec 18, 2009I 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.
