SetVariableValueByPtrMethod

Applies to:Fast Math Parser

Class:uCalc.Item

Sets the value of a variable to a value who's Pointer is passed

Syntax

SetVariableValueByPtr(Value)

Parameters

Value

Pointer

Pointer to the value that the variable will be set to

Returns

Nothing

Remarks

This lets you set the value of a variable by passing the Pointer to the value you want to set the variable to.

Example 1: Setting a variable value by pointer

VB
C#
Delphi
C++
VC++.NET


          
Dim x = uc.DefineVariable("x = 123")
Dim y = uc.DefineVariable("y")

y.SetVariableValueByPtr(x.ValueAddr())

Console.WriteLine(uc.Eval("x")) ' Returns 123


          
var x = uc.DefineVariable("x = 123");
var y = uc.DefineVariable("y");

y.SetVariableValueByPtr(x.ValueAddr());

Console.WriteLine(uc.Eval("x")); // Returns 123;


          
//var x = uc.DefineVariable('x = 123');
//var y = uc.DefineVariable('y');

      y.SetVariableValueByPtr(x.ValueAddr());

      WriteLn(uc.Eval('x')); // Returns 123;


          
auto x = uc.DefineVariable("x = 123");
auto y = uc.DefineVariable("y");

y.SetVariableValueByPtr(x.ValueAddr());

cout << uc.Eval("x") << endl; // Returns 123;


          
auto x = uc.DefineVariable("x = 123");
auto y = uc.DefineVariable("y");

y.SetVariableValueByPtr(x.ValueAddr());

Console::WriteLine(uc.Eval("x")); // Returns 123;
