Form CanExit Event Does Not Execute

[jhackney]

It has been a while since I have messed with a non-xdialog form but I am having a curious issue with a form's CanExit event. I have a form with the following code in CanExit:

msgbox("Can Exit", "Can Exit",UI_OK)

The form is opened in a function as follows:

DIM Shared client_form as P
DIM layout_name as c = "Client"


client_form = :Form.load(layout_name,"dialog")


client_form.new_record()
client_form:Clientid.text = "C1000"
client_form.show()

When using the exit icon on the top right of the dialog, the CanExit event is not triggered. I need to use this to restrict the closing in certain instances and to do some data tests. I cannot put all of this in the forms buttons because this will still leave a back door for the tests to be bypassed using the exit icon. Does anyone know how to deal with this issue?

As the example in the documentation shows, a user closing a form opened as dialog doesn't really close the form (triggering the canexit), they merely hide it.

' the user inputs values into the fields
' the user closes the form, but actually just hides it
'now, really close the form
frm.close()

I would think the canexit event would fire if you add

client_form.close()

after the

client_form.show().

Stan, I originally had client_form.close() at the end but it still did not work. I removed it after I noticed that Alpha 5's action scripting code for opening a form excludes the close() method and ends in show(). I have done a bunch of other things to try and get it to execute to no avail. It just doesn't work as it should. However, if I open the form in design mode and preview it from there, it works.

Yeah, I just did some testing.

Under V11 the canexit event fires when the form is user closed.

Under V12 - 5221-5152, the canexit event doesn't fire when the user closes. Also the user close also seems to remove the form from memory (actually closing it) and the frm.close() throws an error Argument is incorrect data type.

Suggest you send a bug report.

Re: Form CanExit Event Does Not Execute

Stan, I also noticed while I was debugging this issue and still had the close() method in use that it was not allowing access to the pointer fields prior to close(). Example below:

client_form.show()

msgbox("Client ID", client_form:Clientid.text)

client_form.close()

This suggests that the close icon is in fact closing the form instead of hiding it. Once again, documentation does not appear to be accurate.

Stan, can you suggest a workaround? I'm not confident this will be resolved considering it does not affect their current web strategy. At least not in a timely manner.

Not true. If you provide a working example and they can duplicate the problem, it will get fixed. They are making changes internally to be compatible with a new version of dot net. So it's very important that these bugs be reported.

Bug report submitted. I will post when and if it gets fixed.

Re: Form CanExit Event Does Not Execute

I can't think of a workaround. I added a close button but the canexit still didn't fire. Onactivate, ondeactivate don't fire. Oninit and onfetch do.

The problem has already been fixed in the pre-release build.
