VS 2005 - Closing Of A Form

Jun 7, 2012

I am slightly confused on how a form should be closed. I have an exit button and have always done me.dispose in the click event. I just found out this causes the formclosing and formclosed not to be triggered. I found this out because I was updating the live database in the formclosing. Because of this I used me.close but this does not free up all the variables. Do I have to do me.close and then in the formclosed me.dispose in order to close a form correctly?

VS 2008 Closing All Forms When Program Closes Vs. Closing All But Main Form

Jun 4, 2010

Dim 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?

Apr 10, 2011

I have a project using Application Framework and then a main form which displays the main UI. There's another form I call it frmLog, which is solely used for logging any operations internal message logging. By default, I created a Global MyApplication logging object called myLogger which is an object of type frmLog. In Application_StartUp, I instantiate it by myLogger = New frmLog. On the main UI form, there's a button Show Log which does myLogger.Visible = Not myLogger.Visible.

VS 2010 Child Form Tell Parent Form It Is Closing And Send ID?

Apr 2, 2012

I 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.

What I wanted to do is close all opened workbooks. This code does the work IF there is at least one or more opened workbooks. My problem is IF there is NO opened workbook at all; It goes around unendlessly in the WHILE Loop. How do I not process the closing IF there is no any opened workbook at all?

Closing A Form But Keeping The Information In The Form?

Apr 28, 2010

I 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.

Closing Child Form And Parent Form?

Dec 29, 2010

i have a parent form which is having a grid view. In the KeyDown event of the grid view i am calling a child form. 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, 2010

I 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?

Closing Application Via X Button Without Closing Forms Inside Mdiparent Causes Exception Error

May 3, 2010

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?

Closing An Inherited Form ?

Oct 27, 2009

I 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, 2009

I'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
form2.show
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.
