Compares two expressions for inequality

Operatorsoperatordocumented

Syntax

Declare Operator <> ( ByRef lhs As Byte, ByRef rhs As Byte ) As Integer

Declare Operator <> ( ByRef lhs As UByte, ByRef rhs As UByte ) As Integer

Declare Operator <> ( ByRef lhs As Short, ByRef rhs As Short ) As Integer

Declare Operator <> ( ByRef lhs As UShort, ByRef rhs As UShort ) As Integer

Declare Operator <> ( ByRef lhs As Integer, ByRef rhs As Integer ) As Integer

Declare Operator <> ( ByRef lhs As UInteger, ByRef rhs As UInteger ) As Integer

Declare Operator <> ( ByRef lhs As LongInt, ByRef rhs As LongInt ) As Integer

Declare Operator <> ( ByRef lhs As ULongInt, ByRef rhs As ULongInt ) As Integer

Parameters

Name		Description
`lhs`		The left-hand side expression to compare to.
`rhs`		The right-hand side expression to compare to.
`T`		Any pointer type.

Return value

Returns negative one (-1) if expressions are not equal, or zero (0) if equal.

Description

Operator <> (Not equal) is a binary operator that compares two expressions for inequality and returns the result - a boolean value mainly in the form of an Integer: negative one (-1) for true and zero (0) for false. Only if the left and right-hand side types are both Boolean, the return type is also Boolean. The arguments are not modified in any way.

This operator can be overloaded to accept user-defined types as well.

Remarks

Usage



result = lhs <> rhs

Dialect Differences

In the -lang qb dialect, this operator cannot be overloaded.

Differences from QB

none

Example

Dim As String a = "hello", b = "world"

Dim As Integer i = 10, j = i



If (a <> b) Then

  Print a & " does not equal " & b

End If



If (i <> j) Then

  Print "error: " & i & " does not equal " & j

End If

Operator = (Equal) is complement to Operator <> (Not equal), and is functionally identical when combined with Operator Not (Bit-wise Complement).

If (69 <> 420) Then Print "(69 <> 420) is true."

   If Not (69 = 420) Then Print "not (69 = 420) is true."
