How can I call ShowMask inside a DataModule?

[Hayri ASLAN]

To able to show mask in datamodule, you need to call synchronize. We are not suggesting call synchronize in any datamodule event.

Para poder mostrar a máscara no módulo de dados, é necessário chamar a sincronização. Não estamos sugerindo a sincronização de chamadas em nenhum evento do módulo de dados.

What reason do you not indicate?

[Wilton Ergon]

if you are activating a method on the datamodule, using a form, 

start showmask from your form

ex:
procedure tform.clickbutton;
begin
showmask('wait...');
UniSession.Synchronize;
dmfunctions.yourprocedure;
hidemask;
end;

The best way to use a mask is enabling the Mask in associated control such as button.

We don't recommend using Synchronize in such cases.
