Stop form closing

Hi Debbie


You can use the OnQueryCloseForm trigger.

Online Help

The C/AL code in this trigger is executed immediately before the system closes the form.

[Ok]:= OnQueryCloseForm


Ok
Data type: boolean

This return value tells the system whether or not to close the form. The system checks the return value after each function call.


If Ok is... The system...
TRUE Closes the form (default)
FALSE Does not close the form
Applies to
Forms


Comments
If neither the form nor any child form returns FALSE in this trigger, the system calls the OnCloseForm trigger, first for all child forms and then for the form itself (the parent form).

If there is an error in the code in this trigger, the system cancels the close action but does not close the form.

You can write to the database from within this trigger.

Hmm.

what must i do if i will that the Form doesn't closed.
in the Online Help are write that OnQueryCloseForm is executed before OnCloseForm. And that the Form doesn't Close if OnQueryCloseForm are FALSE.

I Have one Value what must be checked before Closed, if the check are ok then it is TRUE if is not ok thenn it is FALSE.

In the OnQueryCloseForm i try ti open an CONFRIM Dialog,
but what ever i click, the Form will close.

I Try with your ERROR() Dialog, but so i don't have any chance to close the Form ... :roll:

Thanks.

Form - OnQueryCloseForm() : Boolean
IF Dialog.CONFIRM('Are you sure?',TRUE) THEN
  Condition := TRUE
ELSE
  Condition := FALSE;
IF NOT Condition THEN 
...

EDIT:
Sorry,...

I have it now...
in my FUnction what must check the value i was give a MESSAGE Out, now i have changed in ERROR Dialog, so no when i will close the form it says me that if a wrong value and after this it asked me if i would now close or not the form.

Hmm. :?

I Have a textbox. In the Textbox Trigger OnValidate a execute a function that must check values, if i put in a value in the textbox, and then i go to close form or i press ESC, then the Forms Close, and after the Form was closed i get my Message that Something was do it. But why the Form is now Closed, it don't have affect.

Hi,

please tell us a little bit more detailed what you want to do.
if i understood you right, then your code may look as follows:

thats right, ...

in the TextBox Trigger OnValidate I execute my Validate function,...
thats okay if after change the value i activate another textbox or control,
but if i change the value without activate another control and i click directly on the closeForm (X) , then the Form will closed, and after it was closed i became the Message that something was do in the validate function.

I Think that i try execute my Function in another trigger and break with ERROR dialog if occurs something.

Other Method that i find nice but now i don't know how make it, is when i close the form that will not take changes to my record. I mean, that if i change the value in my textbox and then close the form that the function what i'm execute in the onvalidate trigger don't execute, the form close and nothing will be saved.

I try now change a little bit the function and try out it in other triggers.


Perhaps follow way is good...
When a record will load in the Form then :

myCheckedVars = TRUE

When then the validate function execute set
myCheckVars = FALSE if validate was false
and
myCheckVars = TRUE if validate was okay

and then when i will close the Form
ask for
myCheckVars

if is TRUE Close and if was wrong too close

hmm.
