如何启动基于控制台的流程并使用 Powershell 应用自定义标题

发布于 2024-09-07 14:01:41 字数 256 浏览 7 评论 0原文

我正在将旧的 cmd 命令转换为 Powershell，当前使用：

START "My Title" Path/To/ConsoleApp.exe

这将按预期启动 ConsoleApp，并将“我的标题”作为窗口标题。它已被替换为 Start-Process，它可以正常工作，但不提供更改标题的机制。

是否有另一种方法可以在不使用 cmd 命令的情况下实现此目的？

I am converting an old cmd command to Powershell, and currently use:

START "My Title" Path/To/ConsoleApp.exe

This works as expected to launch ConsoleApp with My Title as it's window title. This has been replaced with Start-Process which works correctly, but does not provide a mechanism to change the title.

Is there another way to do this without resorting to using the cmd command?

更改进程主窗口的文本时有一个小怪癖：如果您在启动进程后尝试立即更改文本，则可能会由于许多可能的原因之一而失败（例如，显示的控件的句柄）该文本在函数调用时不存在）。因此，解决方案是在尝试更改文本之前使用 WaitForInputIdle() 方法：

Add-Type -TypeDefinition @"
using System;
using System.Runtime.InteropServices;

public static class Win32Api
{
    [DllImport("User32.dll", EntryPoint = "SetWindowText")]
    public static extern int SetWindowText(IntPtr hWnd, string text);
}
"@

$process = Start-Process -FilePath "notepad.exe" -PassThru
$process.WaitForInputIdle()
[Win32Api]::SetWindowText($process.MainWindowHandle, "My Custom Text")

请注意，在您进行自己的更改后，应用程序本身仍然可以更改窗口文本。

There is a small quirk when changing the text of the process' main window: if you try to change the text straight after you have started the process, it may fail due to one of many possible reasons (e.g. the handle to the control which displays the text does not exist at the time of the function call). So the solution is to use the WaitForInputIdle() method before trying to change the text:

Add-Type -TypeDefinition @"
using System;
using System.Runtime.InteropServices;

public static class Win32Api
{
    [DllImport("User32.dll", EntryPoint = "SetWindowText")]
    public static extern int SetWindowText(IntPtr hWnd, string text);
}
"@

$process = Start-Process -FilePath "notepad.exe" -PassThru
$process.WaitForInputIdle()
[Win32Api]::SetWindowText($process.MainWindowHandle, "My Custom Text")

Be aware that the application itself can still change the window text after you have made your own change.

我用 cmd.exe 尝试过，效果很好。

Add-Type -Type @"
using System;
using System.Runtime.InteropServices;
namespace WT {
   public class Temp {
      [DllImport("user32.dll")]
      public static extern bool SetWindowText(IntPtr hWnd, string lpString); 
   }
}
"@

$cmd = Start-Process cmd -PassThru
[wt.temp]::SetWindowText($cmd.MainWindowHandle, 'some text')

I tried this with cmd.exe and it worked well.

Add-Type -Type @"
using System;
using System.Runtime.InteropServices;
namespace WT {
   public class Temp {
      [DllImport("user32.dll")]
      public static extern bool SetWindowText(IntPtr hWnd, string lpString); 
   }
}
"@

$cmd = Start-Process cmd -PassThru
[wt.temp]::SetWindowText($cmd.MainWindowHandle, 'some text')

如果您想使用 powershell 生成一个具有自定义标题的进程，请尝试：

$StartInfo = new-object System.Diagnostics.ProcessStartInfo
$StartInfo.FileName = "$pshome\powershell.exe"
$StartInfo.Arguments = "-NoExit -Command `$Host.UI.RawUI.WindowTitle=`'Your Title Here`'"
[System.Diagnostics.Process]::Start($StartInfo)

注意转义标题字符串的反引号字符，它们至关重要！

If you want to spawn a process with powershell with a custom title try:

$StartInfo = new-object System.Diagnostics.ProcessStartInfo
$StartInfo.FileName = "$pshome\powershell.exe"
$StartInfo.Arguments = "-NoExit -Command `$Host.UI.RawUI.WindowTitle=`'Your Title Here`'"
[System.Diagnostics.Process]::Start($StartInfo)

Note the backtick characters that escape the string for the title, they are vital!
