B4J Question TableView (Line: 0) null

[TAK]

Hello,
I need a simple TableView for my DB, but i get an error. Any idea how to fix this problem?

Thx

Program started.
An error occurred:
(Line: 0) null
java.lang.Exception: Sub appstart signature does not match expected signature.
public static anywheresoftware.b4a.pc.RemoteObject b4j.example.main_subs_0._appstart(anywheresoftware.b4a.pc.RemoteObject,anywheresoftware.b4a.pc.RemoteObject) throws java.lang.Exception

The signature for AppStart sub in Main should be:

Sub AppStart (Form1 As Form, Args() As String)

The error message suggests it isn't, have you changed it?

 

[TAK]

I have this Sub already

Can you zip and post your project

ok,

thx

It looks like you've created a NonUI App, which won't support a Form. Create a new UI App, then copy your code into it.
