MDI Child Forms Are Not Destroyed After They Are Closed?
Dec 19, 2007Do I have to manually call Dispose() when a MDI Child Form is closed? The MDI parent must call for Dispose() or inside the MDI child the call is made?

Detect When A Child Form As Been Closed?
Aug 13, 2010I need a way to detect when a child form has been closed. I've created an MdiWindowList thing (but in the form of a toolbar with buttons, similarly to the Windows taskbar), and everything works great, but the method I have for refreshing the taskbar's windows has to be called when a child form closes. I've trying calling the method from the child's Form_Closing event, but there's a slight lag so whenever there's more than 1 window open the first one gets skipped (then the others close properly, since the taskbar is being refreshed first before the form actually closes).

View 2 RepliesForms :: Detecting Open MDI Childs When MDI Parent Is Closed
Dec 16, 2010I'm new to VB 2010 but have be using VB6 for many years.I'm currently stuck trying to store the state of open MDI childs at the moment the MDI parent is closed. Clicking the parent upper right close button appears to close all open MDI childs before running the parent 'Closing' or 'Disposed' events.I am therefore unable to detect which MDI childs are open and cannot restore them next time the application is run.Is there any other event for the MDI parent I can detect the start of the closing process before the children are closed?

View 3 RepliesVS 2008 - Windows Dialog Forms Hidden But Not Closed
Jan 24, 2010I am using a Windows Dialog form in my VB 2008 project. I bring up the dialog form no problem with the following
Dim resultNewInc As DialogResult
resultNewInc = frmDialog.ShowDialog()
If resultNewInc = DialogResult.OK Then
...some code here ...
End If
And in the Dialog Form, the OK button has code
Me.DialogResult = System.Windows.Forms.DialogResult.OK
Me.Close()
But there is one problem. If I call up the dialog form again, the form controls have the text values that were typed in during the previous instantiation and a class which is part of the form was not disposed. So it looks like the form is being "hidden" and not closed. I tried to use the code form.dispose but it didn't work.

View 2 RepliesMDI Child Forms Not Interacting
May 11, 2012I have a MDI parent on which i launch a child form
Dim NewMDIChild As New Frm_addOT
'Set the Parent Form of the Child window.
NewMDIChild.MdiParent = Me
'Display the new form.
NewMDIChild.Show()
His child form contains several comboboxes which hold data from a dbase(sql)
When new data is entered in the cmb it checks the database and if it isn't in there it launches another window
FRM_OTlistaddklant.Visible = True
and copy's the newly entered text in a textbox.
FRM_OTlistaddklant.TB_klantnaam.Text = OTaddklant_naam
then i can give in the details etc.
now, when this is done and the users presses a button "Add"
the information is written to sql(which works perfect)
than i have a public sub on the Frm_addOT which should refill the combobox and
also set the backcolor to a specific color.
and the last two things will not work. Actually when i try to change the backcolor on Frm_addot it triggers the event backcolorchanged and says it has changed but it is not visible.
MDI Child Forms Resizing
Jan 19, 2011Has anyone ever had or dealt with resizing issues on MDI Child forms? I am working on a VB.Net Windows applciation project I inherited from another devloper. When I took it over the forms had already been designed. There are one MDI Parent Form and two MDI Child Forms. When the application starts up the parent form and one child form open by default. Both the parent form and the child form will maximize, restore, and minimize. Although I have to move the parent form slightly, when it is not maximized I can resize it with the mouse pointer as expected. The child form will not resize and when I move the cursor to the border of the child form I do not even get the mouse pointer. Also, when both the parent and child form are maximized the vertical scrollbar on the child form is no longer displayed.
One potential problem is that there are lots of controls on the child form, which are inside several group boxes. When I comment out the controls, the blank form displays without the vertical scrollbar but will resize with the mouse pointer as expected. When I uncomment the controls the resizing does not work any more. The AutoSize propery on all of the controls is set to True. I tried commenting out the code setting the Autosize property to True on the group boxes only. The result of that is that the resizing still does not work and I lose the vertical scrollbar.I am trying to avoid having to redesign the form completely, however I am running out of alternatives. The project will not pass UAT if the resizing does not work.
MDI Parent And MDI Child Forms?

I've added a form called frmNav and need to designate this and all subsequent forms as MDI child forms. Is there somewhere in each form's properties where I designate this? It used to be in VB6 there was a property called "MDIChild = True." input id="gwProxy" type="hidden"><!-- Session data--></input> <input id="jsProxy" onclick="jsCall();" type="hidden" />

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:
Private Sub btnResults_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnResults.Click
Dim frm2 As frmMale = New frmMale()
AddHandler frm2.FormClosed, AddressOf frm2_FormClosed

A parent form called Sites Primary key is pkSitesID Various other fields On that form I have placed a tab control and in page one I dragged SitesInstallation to it there is a relation created in the DBDiagram to link fkSitesID (in the sitesinstallation table) and pkSitesID
All I want to do is when I navigate through the Sites records the data in the tab page changes according the values I have selected for that given site.
For example: The Siteinstallation maybe Pending or on air.
