Hello Friend,

I'm using GUID() inside my app but I haven't find a method to generate a new GUID,

I tried write GUID() inside a TextInput Default and reset() the TextInput with no luck, any ideas?

Best,

Hi @CaiChicken :
Firstly,let me explain why you encounted this problem.
The point is GUID is a volatile function when used without an argument.For example, a label control for which the Text property is set to GUID() won't change while your app is active. Only closing and reopening the app will result in a different value.
Secondly,please try this solution:
The point is to store the value of GUID in a variable.
1\set the apps's OnStart property to:

Set(varvar,GUID()); /*varvar is my custom variable*/

2\add a textinput control(TextInput4😞
Default:

varvar

3\Add a button:
OnSelect:

Set(varvar,GUID());Reset(TextInput4)

Best Regards,
Bof

An alternative solution if you are using a Global_Reset variable e.g.:

Set(Global_Reset,true); Set(Global_Reset,false);

Then you can use the following formula in the default property of a text input:

If(Global_Reset,"",GUID())

This will call GUID() each time Global_Reset is called
