Read the responses in your previous thread, then read the manual.

Hi
Thanks for reply

In manual they specified that ENTER PROCEDURE is used for forced validation.

I created two forms one is DEPT.FMB, another one is EMP.FMB

DEPT
-------
DEPTNO
DNAME
LOC

At Dname item i created one when-validate-item trigger
i placed code as follows.

ENTER;
CLEAR_MESSAGE;
MESSAGE('HI');
MESSAGE('HI');
CLEAR_MESSAGE;

I placed one button in DEPT form in that i am calling EMP form.
button's mouse and keyboard navigable as NO.

after running DEPT form i entered a value in DNAME .
Now the cursor is in DNAME only.

After i pressed the button.
According to manual
First 'HI' message
After EMP for should open
But here Form is not opening and message is also not displaying
Thats why I asked.

Thanks

'ENTER' is for when you place data in a field, eg, in a When-Button-Pressed trigger, like

begin
  go_item(:blk.itm);
  :blk.itm := 'this is a test';
  enter;
end;

Here the 'enter' causes the validation and automatic navigation to take place.

What is the code you are using to call the EMP form?

Concerning the 'message' issue, please remember that the second message has been LOADED into the message area but will only be shown when a screen refresh is done, eg, by a 'pause' or a 'synchronize'. Doing a call form typically won't do a screen refresh before closing the old form.
