Ejemplos

En el ejemplo de código siguiente se usa el método para convertir números en los valores equivalentes de ToOACurrency Decimal OLE Automation Currency contenidos en Int64 campos.

// Example of the Decimal::ToOACurrency method. 
using namespace System;
#define dataFmt "{0,31}{1,27}"

// Get the exception type name; remove the namespace prefix.
String^ GetExceptionType( Exception^ ex )
{
   String^ exceptionType = ex->GetType()->ToString();
   return exceptionType->Substring( exceptionType->LastIndexOf( '.' ) + 1 );
}


// Display the Decimal::ToOACurrency parameter and the result 
// or exception.
