window doesnt dispose on close???

[Guest]

i have an .ado project with multiple windows. i use this.close to close all
the windows, this makes it run through the closing and dispose functions.
there is 1 window that when closed will run through the closing function but
will not actually dispose until the project closes. any ideas why? the
function call and window calls are all the same, i'm just not sure if i
changed a property or something i didn't notice.

Oscar,

Is this window shown as a modal dialog (Form.ShowModal) in this case Close
method actually hides the form and doesn't dispose it. This is because
normally when dialog is closed one would want to read some of its fields or
maight want to reuse the dialog later.

the window is being called with ShowDialog()

oscar,

In this case as I said the control is hidden and not disposed. You need to
call its Dispose mathod manually.
For example if you don't need to reuse the dialog you can shoe the dialog
like this:

using(MyDlg dlg = new MyDlg(this))
{
if(DialogResult.Ok == dlg.ShowDialog)
{
/// Consume the dialog box data
}
}

this way you'll have the dialog box form disposed as soon as the execution
leaves the using block

That's what I am currently doing, but why is it like this for 1 window? The
other 20 windows do not do this. Is there a setting within the window that
would cause this?

Are the other windows also shown with ShowDialog or just Show? If they
are shown by calling just Show, then they are automatically disposed
when they are closed. If they are shown with ShowDialog, then you must
dispose them manually as Stoitcho said.
