打开文件时指定监视器。（。蝙蝠）

Question

下面的 .bat 文件只是打开两个覆盖它们的文本文件，但我想知道是否可以定义特定的显示源，或者是否有人可以协助提供正确的参数。

@echo off

START /max /wait NOTEPAD.EXE C:\test\screen1.txt

START /max /wait NOTEPAD.EXE C:\test\screen2.txt

我想要得到什么：

@echo off

START /max /wait NOTEPAD.EXE C:\test\screen1.txt "monitor1"  
START /max /wait NOTEPAD.EXE C:\test\screen2.txt "monitor2"

所以我试图收到的结果是 screen1.txt 在监视器 1 上打开， screen2.txt 在监视器 2 上打开。

Answer 1

除非您启动的应用程序具有命令行开关，否则没有简单的方法可以指定在哪个监视器上显示窗口。据我所知，既不start也不notepad支持这样的切换。我发现的最接近的解决方案是在窗口打开后移动窗口。

编辑：从PowerShell调用的user32.dll SetWindowPos()

这是一个混合批处理 + PowerShell 脚本，用于启动程序并将其移动到特定监视器。使用 .bat 扩展名保存它。

<# : batch portion
@echo off & setlocal disabledelayedexpansion

    write-host -f white "     $env:scriptname 1 mp3file.mp3"
    exit 1

原始答案：编译并链接c#可执行文件

移动窗户也不是一件容易的事。请参阅这篇文章了解其他一些选项。但这里有一个批处理脚本，它将动态编写和链接 C# 应用程序以处理窗口移动。

@echo off
setlocal

call :heredoc movewind >"%temp%\c.cs" && goto compile_and_link
// syntax: movewind.exe [pid | "window title"] x y
using System;
using System.Diagnostics;
using System.Runtime.InteropServices;

class movewind {
    [DllImport("user32.dll", SetLastError = true)]
    private static extern bool SetWindowPos(IntPtr hWnd, IntPtr hWndInsertAfter, int x, int y, int cx, int cy, uint uFlags);

    [DllImport("user32.dll", SetLastError = true)]
    static extern IntPtr FindWindow(string lpClassName, string lpWindowName);

    static void Main(string[] args) {
        int pid;
        string title;
        bool res = Int32.TryParse(args[0], out pid);
        if (res) {title = Process.GetProcessById(pid).MainWindowTitle;} else {title = args[0];}
        IntPtr handle = FindWindow(null, title);
        try {
            SetWindowPos(handle, IntPtr.Zero, Convert.ToInt32(args[1]), Convert.ToInt32(args[2]), 0, 0, 0x41);
        }
        catch (Exception e) {
            Console.WriteLine("Exception caught while attempting to move window with handle " + handle);
            Console.WriteLine(e);
        }
    }
}
