Interface And Graphics :: Cancel Close On An MDI Child Form?
May 19, 2012what I want to do is cancel a MDI child form closing when the 'X' at the top right hand side of the form is clicked.So, I use e.Cancel = True in the MDIchild_FormClosing event.However, the parent will not close if the 'X' button is clicked, and I noticed that the FormClosing event of the child handles 'Me', which I assume is the parent.Changing the handles 'Me' to handles 'nameOfChildForm' only generates an error Error: Handles clause requires a WithEvents variable defined in the containing type or one of its base types

View 10 RepliesError On Me.Close() Event Of Form
Sep 15, 2010I have a VB.NET application writtene using VS 2008 and have been receiving a weird error when a form is closed - it gives me the following error message:
Windows has triggered a breakpoint in MyApplication.exe.
This may be due to a corruption of the heap, which indicates a bug in MyApplication.exe or any of the DLLs it has loaded. This may also be due to the user pressing F12 while MyApplication.exe has focus. The output window may have more diagnostic information.
The immediate window then has this error message:
Critical error detected c0000374
I tried fixing this by just hiding the window, but this simply moves the error up the chain and I get an error when exiting the program as it tries to close the form:
Unhandled exception at 0x7700e29b in MyApplication.exe: 0xC0000005: Access violation writing location 0x00000000.
I don't think I'm doing anything particularly strange in my application - reading from and writing to a database is about as complicated as anything gets for me. I've tried using AppVerifier, but then the program won't even open. I'm at a real loss as I don't know anything about memory management, or what a heap is. I just can't work out why this error is happening
By the way, the application compiles and runs fine on my old 32-bit computer running WinXP professional, but my new 64-bit Windows 7 computer is just not having it, even though I have targeted the compile for x86 and followed every bit of advice I could find on geting it to work in Windows 7. Should Windows 7 and VS 2008 really be incompatible? Do I need to get VS 2010 instead?

Form Close In Form Load Event?
Nov 19, 2009I have two forms , first one is search and second is showing the data searched by first form search criteria. When the search query runs it takes lot of sql server resources, so I have passed that query to second form, it searches in database and shows the results. But if the results are not found I wish to close the second form in Form load event. As Second forms form load event searches for the record. I tried to use SecondForm.close in SecondForm.load event but failed to do so.

C# - Detecting The Form Move Event From Within A Child Control?
Jul 8, 2010I am creating a user control where when a user clicks a button a popup window will show up with information. The popup window is driven by a toolStripDropDown so when it shows up it does 2 things
Does not move the other controls on the form around but displays over them That it can show the details outside the bounds of the user control itself without having to reserve the space ahead of time
Here is some code
Public Class Popup
Private treeViewHost As ToolStripControlHost
Private Shadows dropDown As ToolStripDropDown
[Code].....
Now my issue is as the form moves or resizes the Tooldropdown does not move relative. I understand that. When I try to capture the move event of the user control that event does not fire when the entire form moves. There has to be something I can capture because the controls in the container of the form move relative, what drives that? I tried wndproc but nothing fires during form move unless the form is repainted.
Application Firing Shutdown Event On Form Close?
Sep 10, 2010I have a login form that when the user clicks OK and logs in successfully it loads the main application form.However when I show the main form and close the login form, the app is firing the shutdown event.Is this because the app thinks that the login form is the only form open and thus fires the shutdown event?Here is the code for the login routine, when I call Me.Close() at the end is when the shutdown event is fired. Am I doing things out of order? I used to do it this way in VB6 with no problems (I know they're a lot different).Note, it's nothing in frmMain either, this happens no matter what form I try to open.
Private Sub btnOK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnOK.Click

Kill A Form After FormClosing Event Is Overridden To Hide Rather Than Close?
Apr 12, 2010I have a simple Windows Form that hosts property controls at runtime. When the user clicks Close [X] I want to keep the window and its contents alive rather than killing it by handling the FormClosing event, canceling the event and simply hiding the form.
That's fine but at close of the application I need to actually close the window. I implemented the below but it feels kludgey. Is there a simpler, more clever way to handle this situation? (The form's controller calls KillForm explicitly after it receives a closing event from the main window.)[code]...
Two Objects That Are Raising Some Events - Pressing A Button - Raise A Custom Event, Then Execute A Method And Then Close The Form
Mar 30, 2011Problem that you may have when dealing with two objects that are raising some events. Here, to make it obvious, I am closing the form, but the problem can be experienced with any other 2 classes event. First, what is the problem !
Let suppose that by pressing a button, you want to raise a custom event, then execute a method and then close the form
In that case, you may use a code similar to this
Event BeepIt()
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
RaiseEvent BeepIt()

VS 2008 : Modal Form Hide Instead Of Close - Main Form Does Not Close
Mar 20, 2009I have a main form that has a button with which a smaller form is shown. Think of the smaller form as the Find/Replace dialog in many applications, such as Notepad. It's important that the form is (what I believe is called) modal. What I mean is that it always stays on top of the main form. I ensure that by calling the Show method with "Me" as the owner argument. Whenever the small form loses focus it will not disappear into the background but stay visible (albeit out of focus). If you don't understand open up Notepad and have a look at the behavior of the Find/Replace dialog.
Here's my problem: instead of actually closing the form when the X is pressed, I want it to simply Hide itself, so its position and the state of any controls (checkboxes etc) is preserved automatically.To achieve this I simply cancel the FormClosing event and Hide it:
vb.net
Private Sub Form2_FormClosing(ByVal sender As System.Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles MyBase.FormClosing
[code]....
To show the form, I use the following (note the (Me) to make the main form the owner of the form; this ensures that it remains visible even when it is out of focus):
vb.net
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Form2.Show(Me)
End Sub
Now. When I run my project, and open the Form2 (small form), then hide it again (by 'closing' it), I can no longer close the main form (Form1)! It seems the main form cannot close when the small form still exists (albeit invisible)...?? When I don't use the Me argument in the Show method, I don't get the behavior I want. I know I can set the TopMost property to True but that will also cause it to become visible on top of all the other forms, even windows not part of my application.

Oct 5, 2009I have been looking around at how I can close my parent form and my child form. This article: [URL] has some information but it either doesn't work for me or I am putting the wrong information it. What I want to happen is when a button is pressed I want to close both parent and child forms and then go to another form (frmResults). Then there will be a button on frmResults that will take me to the beginning form (frmPTCalculator). With this code below when I click the button on frmCalculator it goes to the MDI form and both parent and child forms are there.
my Parent form is called: frmGender
my Child form is call: frmMale & frmFemale
Below is what I have tried from the example in my Child form frmMale:

Dim frm2 As frmMale = New frmMale()
