Exemplos

O exemplo a seguir foi projetado para uso com o Windows Forms e requer PaintEventArgse, que é um parâmetro do manipulador de eventos Paint. O código executa as seguintes ações:

• Converte um objeto StringFormat em uma cadeia de caracteres.

• Desenha a cadeia de caracteres.

• Altera algumas propriedades no objeto StringFormat.

• Desenha a cadeia de caracteres. A cadeia de caracteres será diferente porque as propriedades do objeto StringFormat foram alteradas.

   StringFormat^ myStringFormat = gcnew StringFormat;

   // String variable to hold the values of the StringFormat object.
   String^ strFmtString;

   // Convert the string format object to a string (only certain information
   // in the object is converted) and display the string.
   strFmtString = myStringFormat->ToString();
