Hi,
In my menus , i have 3 submenu items,
if i click 1st item , call_form('formname'); 1st one will appear,
if i click 2nd menu item , call_form('2ndformname');2nd one will appear,
samething for 3rd item,
finally if i click close int the top of the window, i have to close each form,
My problem is if i click anyone menu item, it should replace or hide the previous window.
I know call_form (hide and replace option was there,but i dnt know how to use ) was there , any other method is there,

Hi,
I have a problem in closing the form,
I have to close previews forms,whenever i open another form,
So any coding s there to findout or check the open_form;
If the form is open i have to close ,
shall use like this:
if open_form('form_name') is not null then
fm_id :=find_form('class');
close_form(fm_id);
end if;

I know where the coding has been placed. My question is | Quote: |
what is the command that you are using to start your application
|
I don't think you can use the Close_Form command to close the CURRENT form. That's probably why the close_form is failing because you are trying to close the current form. You have to do an exit_form to get out of the last/only form that is running.
Use :system.current_form to determine in which form you are currently porcessing. I realise that I suggested using the current_form in a close_form. Sorry, that probably didn't work. Use the current_form to decide where you are and then find and close the other two forms.
