Manuel:

No tengo xHarbour 99.61 para hacer la prueba, me olvide mencionar que uso Windows XP SP2

hola manuel:
tu "ya está solucionado" realmente si funciona!!!
usando tu ejemplo, he creado esta rutina:

#include 'fivewin.ch'
#Include "dll.ch"
#Include "Struct.ch"

FUNCTION MAIN()
LOCAL nResoAncho := GetSysMetrics(0)
IF nResoAncho > 800
CamReso ( 800, 600)
MSGINFO('HECHO. AQUI PUEDES INICIAR TU PROGRAMA ELABORADO PARA 800 X 600')
ENDI
RETU nil

Function CamReso(nAncho, nAlto)
Local DM_PELSWIDTH := nHex("80000")
Local DM_PELSHEIGHT := nHex("100000")
Local oDevMode
Local lPosible
Local cBuffer
Local lCamReso := .f.
DEFAULT nAncho := GetSysMetrics(0), ;
nAlto := GetSysMetrics(1)

STRUCT oDevMode
MEMBER cDevName AS STRING LEN 32
MEMBER nSpecVer AS WORD
MEMBER nDrvVer AS WORD
MEMBER nSize AS WORD
MEMBER nDrvExtra AS WORD
MEMBER nFields AS DWORD
MEMBER nOrientat AS WORD
MEMBER nPaperSiz AS WORD
MEMBER nPaperLen AS WORD
MEMBER nPaperWid AS WORD
MEMBER nScale AS WORD
MEMBER nCopies AS WORD
MEMBER nDefSrc AS WORD
MEMBER nPrnQlty AS WORD
MEMBER nColor AS WORD
MEMBER nDuplex AS WORD
MEMBER nYResolut AS WORD
MEMBER nTTOpt AS WORD
MEMBER nCollate AS WORD
MEMBER cFormName AS STRING LEN 32
MEMBER nUnusePad AS WORD
MEMBER nBitsPPel AS DWORD
MEMBER nPelWidth AS DWORD
MEMBER nPelHeigh AS DWORD
MEMBER nDisFlags AS DWORD
MEMBER nDisFreq AS DWORD
ENDSTRUCT

cBuffer := oDevMode:cBuffer
lPosible := EnumDisplaySettings(0, 0, @cBuffer)
IF lPosible
oDevMode:nFields := nOr(DM_PELSWIDTH, DM_PELSHEIGHT )
oDevMode:nPelWidth := nAncho
oDevMode:nPelHeigh := nAlto
cBuffer:=oDevMode:cBuffer
TRY
ChangeDisplaySettings(@cBuffer, 4)
lCamReso := .T.
CATCH
MsgAlert("Modo no soportado", "Error" )
END
else
MsgAlert("Modo no soportado", "Error" )
endif
return lCamReso

DLL32 FUNCTION EnumDisplaySettings(lpszDeviceName AS DWORD,;
iModeNum AS DWORD, ;
@lpDevMode AS LPSTR) AS BOOL PASCAL;
FROM "EnumDisplaySettingsA" LIB "User32.dll"

DLL32 STATIC FUNCTION ChangeDisplaySettings(@lpDevMode AS LPSTR,;
dwFlags AS DWORD) AS DWORD PASCAL;
FROM "ChangeDisplaySettingsA" LIB "User32.dll"

DLL32 FUNCTION ExitWindowsEx(uFlags AS DWORD,;
dwReserved AS DWORD) AS DWORD PASCAL;
LIB "user32.dll"

ahora puedo usar en cualquier plataforma una resolucion unica de 800 x 600

Muchos Saludos a los que realmente se esfuerzan por darle valor agregado a Fivewin!!!

Maggiro.
Realmente funciona!!!
Veremos mas adelante su comportamiento.
Gracias a todos los que lo hicieron posible.

Hola Julio César,

Me alegro que una rutina hecha hace 6 años, te haya servido. Ya ni me acordaba.

[José Vicente Beltrán]

Pues tengo que decir que para mi ha sido todo un descubrimiento, muy muy util

Muchas gracias una vez mas

¿Sabe alguien como se pueden conocer las resoluciones que admite una pantalla determinada?
no soy capaz de encontrar la función adecuada.

P.e mi monitor admite las siguientes resoluciones 1920x1080, 1600x900, 1280x720 y 800x600

Me gustaria poder saber las resoluciones en tiempo real para recomendar al usuario la mas adecuada a la hora de ejecutar la aplicación.

Gracias anticipadas

Mira se ayuda:

salu2

[José Vicente Beltrán]

Gracias karinha por contestar,

Pero lo que busco es algo parecido (si es que existe) a una funcion que devuelva un array con las distintas resoluciones que admite el monitor en uso.
De forma manual es lo que se hace en windows cuando pulsas en el menu contextual del boton derecho la opción 'resolución de pantalla' y el S.O. te indica las resoluciones que admite el monitor que se está usando.

Gracias de nuevo

Gracias karinha,
voy a investigar en esa dirección.

Puedes probar asi:

Code: Select all  Expand view

#include "Fivewin.ch"
#Include "dll.ch"
#Include "Struct.ch"

Function Main()
    Local aAllRes    := {}

    aAllRes := AllRes()
    if !empty( aAllRes )
       XBrowse( aAllRes )
    endif

Return nil

#define ENUM_CURRENT_SETTINGS   -1
#define ENUM_REGISTRY_SETTINGS  -2

Function AllRes()
Local aAllRes := {}
Local oDevmode
Local oModos
Local i

STRUCT oDevMode
MEMBER cDevName AS STRING LEN 32
MEMBER nSpecVer AS WORD
MEMBER nDrvVer AS WORD
MEMBER nSize AS WORD
MEMBER nDrvExtra AS WORD
MEMBER nFields AS DWORD
MEMBER nOrientat AS WORD
MEMBER nPaperSiz AS WORD
MEMBER nPaperLen AS WORD
MEMBER nPaperWid AS WORD
MEMBER nScale AS WORD
MEMBER nCopies AS WORD
MEMBER nDefSrc AS WORD
MEMBER nPrnQlty AS WORD
MEMBER nColor AS WORD
MEMBER nDuplex AS WORD
MEMBER nYResolut AS WORD
MEMBER nTTOpt AS WORD
MEMBER nCollate AS WORD
MEMBER cFormName AS STRING LEN 32
MEMBER nUnusePad AS WORD
MEMBER nBitsPPel AS DWORD
MEMBER nPelWidth AS DWORD
MEMBER nPelHeigh AS DWORD
MEMBER nDisFlags AS DWORD
MEMBER nDisFreq AS DWORD
ENDSTRUCT

    oModos := oDevMode:cBuffer
    i := 0
    do while .T.
       if (EnumDisplaySettings(0, i, @oModos ))  
       AAdd( aAllRes, { oDevMode:nPelWidth, oDevMode:nPelHeigh, ;
                        oDevMode:nBitsPPel, oDevMode:nDisFreq } )
       i++
       else
         exit
       endif
    Enddo

    //? Len( aAllRes )

Return aAllRes

@lpDevMode AS LPSTR) AS BOOL PASCAL FROM "EnumDisplaySettingsA" LIB "User32.dll"

Cristobal,
Es exactamente lo que buscaba, lo tenia delante de las narices y no he sido capaz de verlo
Muchas gracias
