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?
.net - Calling New StackTrace Blocks When Closing Application
Sep 12, 2011I just did some analysis by using a global function which is called GetCallingMethod in my case.
Mostly it works great. But some cases the application is blocked. It is blocked when closing the application. When going to "pause" in Visual Studio, it stays on the new StackTrace line forever.
In my application I am using third party references, multithreading and several classes. But all that should not be a problem and should not lock the tracer class as far as I imagine. I am using Visual Studio 2010 Ultimate in this case.
This line will never be left in development area. Application will is frozen. Try/Catch will not force the procedure.

VS 2010 Child Form Tell Parent Form It Is Closing And Send ID?
Apr 2, 2012I have a parent form that has a list of items and each item has a unique ID. The user can open one or many of the items in a child form (it is set up in a tabbed MDI), but it can only open one instance of each item at a time.
In the parent form, I was going to make a collection (or something like that, maybe there is a better way) to keep track of which items are open in the child forms. I need to know when each child is closed so that it can be removed from the collection and reopened at a later time. I was thinking that when the child form closes, it somehow does something (like raise an event) that tells the parent form to remove the unique ID from the list of current open child forms.
My questions are, is this a good way to do this and I am pretty sure I would use the form closed event in the child form to update that parent form, but as well, I didn't know if this is the best way of handling it.
If raising the event is a good way, are some examples on how to do it out there? I found some for controls, but not while the form is closing/closed.
Closing A Form But Keeping The Information In The Form?
Apr 28, 2010I am working on a project that has the user building scrapbook pages through several different forms. When the user selects something a presses a button I have the information about the selection load to a list box which is on a CheckoutForm. One of the options I have is for the user to save what they have made (this includes the information in the list boxes) and return to a previous form to build another page. I have been trying to use the Me.Close() but it does not save the information and using Me.Hide() displays the wrong elements on the forms.

If the user closed the child form, my application should close both the parent form and child form. What i have done is, i declared a boolean in the child form and passed the boolean value to parent. May be the code below will give the picture of what i am trying to do.

Fire A Method On A Different Form When Closing A Form?
Jun 22, 2010I have a unique challenge that I just cannot seem to get by...I have a form with a series of listboxes that allows the user to rename items in the listbox (I probably should be using a listview control instead). When the user right-clicks and selects rename from the context menu I show a simple form with two labels & text boxes showing the selected list box item in one textbox...the other is blank waiting for the user to enter a new name. What I'd like to do is when the user closes the rename form, the information is passed back to the calling form and a listbox refresh method is fired to show the changed name. Couple question:
First, is there an easier method to implement the renaming concept in a listbox (probably should be using a list view) i.e., have I overcomplicated things?

Calling Showdialog() On A Form - From The Main Form's OnLoad Event Makes The Modal Dialog Go Away After A Few Seconds?
Aug 7, 2009I'm having an interesting issue that I can't reproduce on a different project, but can consistently on this one. I have no clue what might be causing it, but am hoping that someone may have seen it before.
I have a main form, from which I run a series of checks. On this form, I have a listview control. Because of some issues with the refreshing of this listview control, I had to create my own messagebox. It's just a form that displays some text ( it also happens to look nicer than MsgBox; in my opinion, anyways ). It's been working great for months, until recently.
My problem is that on my main form's load event, I run this check, which returns an error within a try/catch block. I then call my custom messagebox with a message. It in turns calls it's ShowDialog() function.
In any other situation ( after the main form has been loaded ), I have no problems. The messagebox goes on the screen and behaves appropriately ( ie: waits for my input and acts as a modal dialog ( stops execution of my main form's thread ) ). However, on this onload event, my messagebox comes up and goes away almost immediately afterwards.
I've traced it all the way to the showdialog() call. For no explicable reason, it appears to skip right over this call, without me doing anything on the form.
Here's what the inner trace looks like ( when I put a breakpoint on the onclosing event for this messagebox 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?

View 3 RepliesClosing An Inherited Form ?
Oct 27, 2009I am having a problem with closing a form which I have inherited I have a form called frmAddForm_Simple, which contains 4 main controls (A Data Grid, A Save Button, A Close Button and a Text Box). The idea around the form is to create a form which could be used for inputting of many different types of data which are all entered in the same way (i.e. to add a new row to a database for [Status] table or [Location] table, all of which contain 2 columns in the database (an [Id] and a [value]). On the form I have a property called _FormChanged, which when the textbox text changes, sets the property to True. I then have the following code on the Close Button:-
Public Sub btnClose_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnClose.Click
If _FormChanged Then
If MessageBox.Show("Are you sure you want to close and discard any changes?", "Discard Changes",
[CODE]...
Is opened as a dialog (ShowDialog) and when I go to close the inherited form (by click on btnClose) and answer No to the above MessageBox the form closes anyway. Using the Debugged I have worked out that the following events occur in sequence (all of which runs in the Master Form mentioned above):-
1) btnClose_Click sub Routine runs
2) I answer No to the question do I want to close the form
3) The debugger steps over the Me.Close() line (as expected)
4) The debugger jumps up to the Sub Initialise (where ShowDialog was called from) and closes the form.
So at no point has the debugger even ran a line of code which reads Me.Close(), but the form closes anyway so Im fairly confused as to why the form should close.
My Master Form (frmAddForm_Simple) Code:-
Public Class frmAddForm_Simple
Private _FormChanged As Boolean = False
Private _FormLoading As Boolean = False

Closing Form And Loading Another
Mar 6, 2009I've got 2 forms; form1 and form2.
Button1 is added to form1.
When I click button1, I want to close form1 and open form2.
I tried the following.
me.close

Its not working. Form1 gets closed but form2 is not showing up.
When I use the following code
me.hide
form2.show, its working.
But hide will not unload form1 and it will still occupy memory.

How Could Application Form In Vb Be Closing By Itself
Feb 24, 2012I have a form in a Pocket PC app that is set to be the Application form using:Application.Run(New frmMain())Somehow this form is getting closed for no reason while working on another form. No closing event is fired and nowhere in my code can you close the main form anyway. It is only closed by clicking the OK button at the top right of the window. When this is clicked, the user is prompted if he/she really wants to close the application. However, this is not occurring either.Basically, I am on another form which adds a new record to the database. After adding the record the gotFocus event is somehow called for frmMain. When the code in the gotFocus event reaches a reference to a control on the form, there is an exception that states that the object is disposed.

Jun 28, 2010I have a test app driven by bluetooth serial events In my form load code I hide the cursor so it doesn't get in the way of pictures (fullscreen)When one event is called by bluetooth, it brings up a msgbox and the user has to click OK. I tried Windows.Forms.Cursor.Show() but it doesn't work.
I'm guessing it's something to do with delegates and events and the form, but the debugger doesn't complain at any point. It just refuses to show the cursor.How can I get my serialport event to show the cursor? And then hide it after?
Start A New Form On Closing One?
Feb 14, 2010When my program runs it closes form1 after a few seconds. Depending on what happened during form1's lifespan I may want to open form2. Normally I would just make a new instance of form2 and use the show() method. But form2 is then a child of form1 and then also closes.
