如何在vb中使与应用程序无关的窗口最小化或最大化其窗口状态？

如果您在任务管理器中注意到，当您右键单击正在运行的任务时，您会看到许多选项，其中包括“最小化”和“最大化”。有没有办法在vb中实现这个目标？

这是您正在寻找的代码的示例。它将循环遍历所有活动进程并最小化所有窗口。

在您的应用程序中，您可能需要使用类似 Process.GetProcessesByName 的方法来查找要操作的特定窗口。

Imports System.Runtime.InteropServices

Module ManipulateWindows

    Const SW_HIDE As Integer = 0
    Const SW_RESTORE As Integer = 1
    Const SW_MINIMIZE As Integer = 2
    Const SW_MAXIMIZE As Integer = 3

    <DllImport("User32")> _
    Private Function ShowWindow(ByVal hwnd As Integer, ByVal nCmdShow As Integer) As Integer
    End Function

    Public Sub Main()

        'iterate through all the open processes.
        For Each p As Process In Process.GetProcesses    

            'Get the Window Handle
            Dim hWnd as integer = CType(p.MainWindowHandle, Integer)

            'Write out the title of the main window for the process.
            System.Console.WriteLine(p.MainWindowTitle)

            'Minimize the Window
            ShowWindow(hWnd, SW_MINIMIZE)
        Next p    
    End Sub    
End Module

Here is an example of the code you are looking for. It will loop through all the active processes and minimize all the windows.

In your app you will probably want to use something like Process.GetProcessesByName to find the specific window you want to manipulate.

Imports System.Runtime.InteropServices

Module ManipulateWindows

    Const SW_HIDE As Integer = 0
    Const SW_RESTORE As Integer = 1
    Const SW_MINIMIZE As Integer = 2
    Const SW_MAXIMIZE As Integer = 3

    <DllImport("User32")> _
    Private Function ShowWindow(ByVal hwnd As Integer, ByVal nCmdShow As Integer) As Integer
    End Function

    Public Sub Main()

        'iterate through all the open processes.
        For Each p As Process In Process.GetProcesses    

            'Get the Window Handle
            Dim hWnd as integer = CType(p.MainWindowHandle, Integer)

            'Write out the title of the main window for the process.
            System.Console.WriteLine(p.MainWindowTitle)

            'Minimize the Window
            ShowWindow(hWnd, SW_MINIMIZE)
        Next p    
    End Sub    
End Module
