Al parecer la librería "swedll32.dll" si está documentada y aparentemente tiene un nicho de usuarios importante. Buscando información al respecto encontré el siguiente dato:

(tomado de stackoverflow) Antes de llamar a swe_calc_ut usted debería colocar un Path a un folder con los datos de "ephe" con algo similar a lo siguiente :

Código PHP:

[DllImport("swedll32.dll", CharSet = CharSet.Ansi, EntryPoint = "swe_set_ephe_path")]
private static extern void swe_set_ephe_path(String swe_path);

swe_set_ephe_path(@"c:\path\to\ephe\"); 


Tal vez está información sea de utilidad para compuin.

Atento a sus comentarios

[mamcx]

El asunto es que en una "marea" de codigo es facil perderse:

http://www.dreamsongs.com/ObjectsHaveNotFailedNarr.html

Muestrame tus flujos y esconde tus tablas, y me mantendrás estupefacto. Muestrame tus tablas y usualmente no necesitare tus flujos, estos serán obvios.

Show me your flowchart and conceal your tables, and I shall continue to be mystified. Show me your tables, and I won't usually need your flowchart; it'll be obvious.
--Fred Brooks, in Chapter 9 of The Mythical Man-Month

Por lo que veo del codigo, esta muy complicado. Tiene DEMASIADAS constantes, abreviaciones y demás que no dejan claro qué es que. Es mas simple escribir funciones cortas que resuelven tareas especificar, y unirlas reduciendo al minimo el uso de variables de estado. Para simular el uso de "tablas" y hacer evidente la estructura del programa, usa en Delphi Records(mejor pa este caso)/Objetos.

Asi, por ejm:

Código Delphi [-]
type
   TPlaneta = (SE_MERCURY, SE_VENUS, ...); 

TPlanetaMedicion = Record
    nombre: TPlaneta
    ..
    ..
  end;

procedure medir(planeta : TPlaneta): TPlanetaMedicion;

Nota bien lo interesante. Usando records/clases como si modelaras las "tablas" de una BD vas dandole forma a la estructura conceptual del programa, y al usuarlo en funciones/metodos se vuelve claro cual es el flujo de este: "medir TPlaneta me retorna un TPlanetaMedicion".

El programa se AUTO DOCUMENTA cuando usas los nombres/clasificaciones/tipos de datos adecuados. De allí es copiar datos y calcular. Ademas, en Delphi tienes enumeraciones y sets, que son superiores (logicamente) que clavar constantes como ocurre con SE_MERCURY y similares.

Aunque pueden haber expeciones, si un metodo/funcione tiene "muchas" lineas *tal vez* es buena idea partirlo en sub rutinas (o agregas marcas con comentario en las secciones).

El truco que dice Fred Brooks es que estructurar los datos clarifica el programa mientras el codigo "duro" lo obscurece.

Con respecto a copiar arrays, es mejor que aprendas como usar iteraciones y LOW/HIGH para capturar las posiciones del mismo:

De entrada y sin entrar en el funcionamiento del código veo que tienes una unit con las definiciones para usar swedll32.dll desde delphi. Eso implica que debes incluirla en el uses y no repetir de nuevo nada.


Tu código debe quedar mucho más sencillo y resumiendo esto es la parte que interesa:

El código es un galimatías. Debes ir con orden. Primero inicializaciza los ComboBox en funciones de inicio o en el Form.Create.
Luego darás funcionalidad a los botones...

Debes estudiar el uso de esa dll pues al parecer debes inicializar con una ruta que debe contener previamente algunos archivos y quizás requiera más acciones. Este punto es básico y piensa que probablemente ninguno de nosotros estamos familiarizados con esa dll, ese es tu cometido.

Cuando requieras preguntar alguna cosa concreta, trata de aislar en lo posible el código que te preocupa y que sea suficiente para entenderte pero no tán sobrecargado que se pierdan las ganas de leerlo.

Ahora fíjate en este código:

Código Delphi [-]
uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls, DateUtils, swiss;
.............................



var
  i, iflag: integer;
  xx:       array[0..5] of double;
  planet:   array [1..12] of double;
  serr:     PChar;
  JulDay:   double;
begin
  swe_set_ephe_path(PCHAR('c:\sweph\ephe\'));
  JulDay:= DateTimeToJulianDate(Date);
  for i:= 1 to 12 do
  begin
    swe_calc_ut(Date, i, SE_ECL_NUT, xx[0], serr);
    planet[i]:= xx[0];
  end;
end;

El array es asignado correctamente, otra cosa es que los valores sean los experados.

Fíjate que arroja un error serr = 'SwissEph file 'seplm48.se1' not found in PATH 'c:\sweph\ephe\'' para todos los valores de i hasta para I=10.

Para i= 11 el error es 'SwissEph file 'semom48.se1' not found in PATH 'c:\sweph\ephe\'' y para i=12 no falla


Esto quiere decir que en ese path deben existir previamente esos archivos y probablemente alguno más.

Entonces la pregunta no es como rellenar un array, sino como manejar swedll32.dll para conseguir el array que esperamos.


Saludos.

[[escafandra]]

Pero si lo usamos así:

Código Delphi [-]
procedure TForm1.Button1Click(Sender: TObject);
var
  i, iflag: integer;
  xx:       array[0..5] of double;
  planet:   array [1..12] of double;
  serr:     PChar;
  JulDay:   double;
begin
//  swe_set_ephe_path(PCHAR('c:\sweph\ephe\'));
  JulDay:= DateTimeToJulianDate(Date);
  iflag := 0;
  for i:= 1 to 12 do
  begin
    swe_calc(Date, i, iflag, xx[0], serr);
    planet[i]:= xx[0];
  end;
end;

Entonces no hay errores y los valores son:

0
0
0
0
0
0
0
0
0
188,01570562548
0
200,800942459646

Ahora bien, no tengo ni idea si eso es lo que se espera para la fecha de hoy.
