A Structure is an organized group of information that defines a specific data set. There are many types of structures available in B4X, including Classes, database records, Maps, and custom types.

It's better to create "specialized" types but you could also create a generic type: Type tTwoValues(Value1 As Object, Value2 As Object) This way you will be able to use it in many situations.

A custom type is a bag of fields with zero logic. You know what you are getting. This can be an advantage. Properties vs. public variables is a mat

1. Using activities instead of B4XPages. 2. As DonManfred wrong. Best to delete the global variables, hover over the type -> generate Create sub and use it: Private Sub pnlGraph_Touch (Action As Int, X As Float, Y As Float) Dim v As Vertex = CreateVertex(...)
link: you are reusing a global type. Instead you should create a new one, fill the data and add the new reference to the list. something like this? Sub G

The correct type is PhoneVibrate.

The following data types are available in B4R: Numeric types: Byte: 0 - 255 Int (2 bytes): -32768 - 32768. Similar to Short type in other B4X tools. UInt (2 bytes): 0 - 65535. Long (4 bytes): -2,147,483,648 - 2,147,483,647. Similar to Int type in other B4X tools. ULong (4 bytes): 0 - 4,294,967,295

The field type is Decimal(10,2) not REAL. CREATE TABLE "tblBilling" ( "ID" INTEGER NOT NULL, "ClientID" INTEGER, "ProviderID" INTEGER, "WeekEndDate" SmallDateTime, "TotalHours" Decimal(10, 2), "ActualTotalHours" Decimal(10, 2), "PaidAmount" Decimal(
