SetVariableValueAny

SetVariableValueAnyMethod

Sets the value of a variable of any data type by passing a string

Syntax

SetVariableValueAny(Value)

Parameters

Value

String

String containing the value that will be converted and stored in the variable

Returns

Nothing

Remarks

This lets you set the value of a variable defined with DefineVariable (or Define) regardless of the variable's data type. The value is passed as a string, and internally converted to the appropriate data type. Note: Because a conversion takes place with SetVariableValueAny, it is typically slower than calling SetVariableValue for floating point, or one of the other versions of SetVariableValue specific to a data type.

Example 1: Setting variables of any data type

Dim Int32Var = uc.DefineVariable("Int32Var As Int32")
Dim ByteVar = uc.DefineVariable("ByteVar As Byte")
Dim StrVar = uc.DefineVariable("StrVar As String")
Dim SngVar = uc.DefineVariable("SngVar As Single")

Int32Var.SetVariableValueAny("4.25"): ' Will be converted to integer
ByteVar.SetVariableValueAny("-1"): ' Will be converted to unsigned byte
StrVar.SetVariableValueAny("'Test'")
SngVar.SetVariableValueAny("1.25")

Console.WriteLine(uc.Eval("Int32Var")) ' Returns 4
Console.WriteLine(uc.Eval("ByteVar")) ' Returns 255
Console.WriteLine(uc.EvalStr("StrVar")) ' Returns "Test"
Console.WriteLine(uc.EvalStr("SngVar")) ' Returns 1.25

      StrVar.SetVariableValueAny('"Test"');
      SngVar.SetVariableValueAny('1.25');

      WriteLn(uc.Eval('Int32Var')); // Returns 4;
      WriteLn(uc.Eval('ByteVar')); // Returns 255;
      WriteLn(uc.EvalStr('StrVar')); // Returns 'Test';

cout << uc.Eval("ByteVar") << endl; // Returns 255;
