[solved] Can't mix strings with numerical values

[falsam]

Hello there ^^

I have a problem with this code.

Code: Select all

;-New message from an user
  !socket.on('usermessage', function(v_data) {
  !   v_username = v_data.username;
  !   v_usermessage = v_data.message;
  AddGadgetItem(#userHistoric, 0,  username + Chr(10) + usermessage)
  !});

AddGadgetItem generates an error message

Can't mix strings with numerical values.

If I replace

Code: Select all

AddGadgetItem(#userHistoric, 0,  username + Chr(10) + usermessage)

with

Code: Select all

AddGadgetItem(#userHistoric, 0,  "" + username + Chr(10) + usermessage)

I do not have this error message.

Thanks for your help.

You need to declare username with a string type before using it in inline JS. When not using Str(), the string expression needs to start with a string value, not a numeric one.

Hello falsam,

what about this one?

Code: Select all

;-New message from an user
  Define username.s
  Define usermessage.s
  !socket.on('usermessage', function(v_data) {
  !   v_username = v_data.username;
  !   v_usermessage = v_data.message;
  AddGadgetItem(#userHistoric, 0,  username + Chr(10) + usermessage)
  !});
