如何使與應用程序無關的窗口最小化或最大化其在vb中的窗口狀態？

Question

如果您在任務管理器中注意過，當您右鍵單擊正在運行的任務時，您有許多選項，包括「最小化」和「最大化」。無論如何要做到這一點在VB中？

Answer 1

以下是您正在尋找的代碼示例。它將遍歷所有活動進程並最小化所有窗口。

在您的應用程序中，您可能會想使用類似Process.GetProcessesByName的東西來查找您要操作的特定窗口。

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
