¿cómo verificar la resolución de pantalla de Windows?

[karinha]

Buenas tardes señores, ¿cómo verificar la resolución de pantalla de Windows, a través del comando FiveWin? ¿Necesito informar o tomar una decisión sobre qué DIÁLOGO "Cargar"? Estoy creando varios DIÁLOGOS para diferentes resoluciones de pantalla.

Gracias,

¿Podría alguien probar este código en WINDOWS 10 o WINDOWS 11 y decirme si funciona o no?

Buenas tardes señores, ¿cómo verificar la resolución de pantalla de Windows, a través del comando FiveWin? ¿Necesito informar o tomar una decisión sobre qué DIÁLOGO "Cargar"? Estoy creando varios DIÁLOGOS para diferentes resoluciones de pantalla.

Busca ScrResolution()

Creo que te servirá.

¿Cuál es el comando equivalente en FiveWin?

Code: Select all | Expand

#include "FiveWin.ch"

Static nWIDTH
Static nHEIGHT

FUNCTION Main()

   nWIDTH  := GetDesktopWidth()
   nHEIGHT := GetDesktopHeight()

FiveWidi, ScrResolution()? No he encontrado nada en este sentido que me funcione o no lo entiendo. Lo que quiero saber es cuál es la resolución del monitor que el usuario (cliente) ha configurado en su máquina (computadora) y, a partir de esta información, decirle al programa que busque/cargue el cuadro de diálogo Resolución del monitor (video) que eligió el cliente, ¿comprender?

João:
Probe tu programa y mi resolucion es: 1366 x 768
Tu programa me indica un mensaje que dice 1280 x 768
Y me sale un cartel de Windows que indica que la resolucion optima es 1366 x 768
Hace un parpadeo previo y pos cierre del programa.
Como para que tengas de referencia.
Saludos

Gracias César Gómez. Sospechaba que en Windows 10 esto no funcionaría. En Windows 7 de 32 bits funciona perfecto, pero hoy en día la mayoría de los clientes usan Windows 10 por ley aquí en Brasil. sigo investigando Muchas gracias.

   nResHoriz := GetSysMetrics(0)
   nResVert  := GetSysMetrics(1)
 

Mi idea era tener un solo diálogo para una RESOLUCIÓN DE PANTALLA 1280 x 768 y cambiar la resolución de pantalla del cliente a 1280 x 768 en tiempo real, y al salir del programa, volvía a su resolución de pantalla original. Pero, como el programa de ejemplo anterior no funcionó en Windows 10, voy a usar GetSysMetrics() para averiguar qué cuadro de diálogo (WS) usará el programa, va a ser mucho trabajo, pero no lo he hecho. No he visto otra solución.

Gracias,

Una solución por el momento para no bloquear Windows 10. Las sugerencias siempre son bienvenidas.

En Windows 7 de 32 bits, esto funciona perfecto. En windows 10, NO! Una Lástima. jejejejejeje.

Master Antônio, la razón por la que no funciona en Windows 10, ¿tiene algo que ver con esta función de micro$oft?

hi,

to get (real) "native" Resolution you can use

Hello Jimmy. I think you didn't understand what I want. Please, to understand, you need to test the example I posted above on a machine with WINDOW 7 and then on a machine with WINDOWS 10, then you will understand what I want, ok?

Tks
