WhatsApp tests

[Antonio Linares]

Modesto Rocabado has shared with us this code to send messages and files using WhatsApp.

We do appreciate your tests and feedback to fine tune it. Many thanks!

Dear Antonio,

Thank you very much for the code and the suggestion with the key combination symbol ~ (which stands for "Enter").

I just did a test and it works. I only tried text. It seems that you need to have WhatsApp installed on the PC. On the server via RDP with the administrator, I get this info:

This app cannot be activated by the built-in administrator account.


Best regards,
Otto

Antonio,




I make a small test but I have allways errors

How can you remove the ability to have attachments or not?
then the function should check if the WhatsApp application is installed on the PC and load it directly from the Microsoft store but I don't know how to do it

the link to download is "https://apps.microsoft.com/detail/9nksqgp7f2nh?hl=it-it&gl=IT"

Antonio, a partir de que version funciona?
Porque me da error en FW_CopyToClipBoard( aFiles, 15 )

[cmsoft]

SetClipboardData me devuelve NIL y por eso me falla la funcion

[cmsoft]

Funcionó bien!
Depende de donde estemos parado (si en el texto para enviar, en buscar, etc) del Whatsapp para que funcione correctamente.
Pero si arrancamos poniendo el cursor en donde se debe escribir el mensaje, funciona
Igualmente sigo haciendo pruebas.

[Antonio Linares]

César,

muchas gracias por tus pruebas!

[Silvio.Falconi]

on my computer it simply opens the WhatsApp application but in cases where it is not installed,

the procedure should check if it is installed and if it is not, go and download the application from the Microsoft store

However it doesn't work for me, I tried to send it to a friend and nothing arrived

opens the whatsapp application but then doesn't send anything

if it finds the number on whatsapp it goes into the chat of the called number but then does not send anything, while if you enter an incorrect number the number not found information message arrives
