vb利用FindWindow，GetWindowText，SendMessage查找程序并发送最

' 查找运行的窗体 Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String,ByVal lpWindowName As String) As Long Private Declare Function GetWindowText Lib "user32" Alias "GetWindowTextA" (ByVal hwnd As Long,ByVal lpString As String,ByVal cch As Long) As Long ' 发送系统消息 Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long,ByVal wMsg As Long,ByVal wParam As Long,lParam As Any) As Long Private Const WM_CLOSE = &H10 Private Const WM_SYSCOMMAND = &H112 Private Const SC_CLOSE = &HF060& Private Const SC_MINIMIZE = &HF020& Private Const cch = 255 ' Private Declare Function TerminateProcess Lib "kernel32" (ByVal hProcess As Long,ByVal uExitCode As Long) As Long Private Declare Function OpenProcess Lib "kernel32" (ByVal dwDesiredAccess As Long,ByVal bInheritHandle As Long,ByVal dwProcessId As Long) As Long Private Declare Function CloseHandle Lib "kernel32" (ByVal hObject As Long) As Long Private Declare Function CreateToolhelpSnapshot Lib "kernel32" Alias "CreateToolhelp32Snapshot" (ByVal lFlags As Long,ByVal lProcessID As Long) As Long Private Declare Function ProcessFirst Lib "kernel32" Alias "Process32First" (ByVal hSnapShot As Long,uProcess As PROCESSENTRY32) As Long Private Declare Function ProcessNext Lib "kernel32" Alias "Process32Next" (ByVal hSnapShot As Long,uProcess As PROCESSENTRY32) As Long ' Private Declare Function ShowWindow Lib "user32" (ByVal hwnd As Long,ByVal nCmdShow As Long) As Long Private Const TH32CS_SNAPPROCESS = &H2 Private Const TH32CS_SNAPheaplist = &H1 Private Const TH32CS_SNAPthread = &H4 Private Const TH32CS_SNAPmodule = &H8 Private Const TH32CS_SNAPall = TH32CS_SNAPPROCESS + TH32CS_SNAPheaplist + TH32CS_SNAPthread + TH32CS_SNAPmodule Private Const MAX_PATH As Integer = 260 Private Const PROCESS_ALL_ACCESS = &H100000 + &HF0000 + &HFFF Private Type PROCESSENTRY32 dwSize As Long cntUseage As Long th32ProcessID As Long th32DefaultHeapID As Long th32ModuleID As Long cntThreads As Long th32ParentProcessID As Long pcPriClassBase As Long swFlags As Long szExeFile As String * 1024 End Type Private Sub Form_Load() Dim hwnd As Long Dim lpString As String * 256 hwnd = FindWindow(vbNullString,"Macromedia Flash Player 8") Label1.Caption = hwnd Label2.Caption = Left(lpString,GetWindowText(hwnd,lpString,cch)) 'MsgBox SendMessage(hwnd,WM_CLOSE,0) '关闭窗体命令 'MsgBox SendMessage(hwnd,WM_SYSCOMMAND,SC_MINIMIZE,0) 'MsgBox SendMessage(hwnd,SC_CLOSE,0) Dim MySnapHandle As Long Dim hProcess As Long Dim ProcessInfo As PROCESSENTRY32 MySnapHandle = CreateToolhelpSnapshot(TH32CS_SNAPPROCESS,0) ProcessInfo.dwSize = Len(ProcessInfo) If ProcessFirst(MySnapHandle,ProcessInfo) <> 0 Then Do If Left(LCase(ProcessInfo.szExeFile),InStr(ProcessInfo.szExeFile,".") + 3) = "flash.exe" Then '遍历进程,查找unmsg.exe，找到后执行操作.......，进程名全小写 hProcess = OpenProcess(PROCESS_ALL_ACCESS,False,ProcessInfo.th32ProcessID) TerminateProcess hProcess,1 CloseHandle hProcess End If Loop While ProcessNext(MySnapHandle,ProcessInfo) <> 0 End If CloseHandle MySnapHandle End Sub

以上代码实现最小化、关闭指定的程序，然后结束进程

vb6 + xp sp3 测试通过

更简单的方法 ' 发送最小化命令，Alt+空格，然后按N键 SendKeys "%{ }+n",True
