用以学习EnumWindowsProc、SendMessage、WindowFromPoint、WindowFromPoint、ShowWindow、EnableWindow、FindWindow等等API的用法
共有3个窗体,分别为form1,form2,form3,和一个模块Module1
form1代码:form1有label(0~5)标签,text1、text2.。。。text5等5个textbox
form2代码:form2只有一个listview1控件
form3是菜单,无控件,菜单内容请看代码:
module1的代码:
仅供大家参考学习,偶尔用于解除某些软件中按钮的限制,呵呵,当然不要报太大希望,人家都有防止此类情况的措施的。

共有3个窗体,分别为form1,form2,form3,和一个模块Module1
form1代码:form1有label(0~5)标签,text1、text2.。。。text5等5个textbox
Private Sub Form_Load() Success = SetWindowPos(Me.hwnd, -1, 0, 0, 0, 0, 3) Me.Left = Screen.Width - 1900 Me.Top = Screen.Height - 1710 End Sub Private Sub Form_Unload(Cancel As Integer) End End Sub Private Sub Label1_MouseUp(Index As Integer, Button As Integer, Shift As Integer, x As Single, y As Single) If Button And 2 Then PopupMenu Form3.tfile End Sub Private Sub Timer1_Timer() If GetAsyncKeyState(vbKeyF2) Then Form2.ListView1.ListItems.Clear EnumChildWindows Text1.Text, AddressOf EnumWindowsProc, ByVal 0& Form2.Show End If If GetAsyncKeyState(vbKeyF3) Then Clipboard.Clear Clipboard.SetText Text4.Text MsgBox "窗口标题已保存至剪贴板。", vbOKOnly, "提示" End If Static lX As Long, lY As Long, stayTime As Long On Local Error Resume Next Dim P As POINTAPI, h As Long, hD As Long, r As Long GetCursorPos P lX = P.x: lY = P.y Px.x = P.x Px.y = P.y '设备环境是一个结构,它定义了一系列图形对象及其相关的属性,以及会影响输出结果的绘图方式。这些图形对象包括:画笔(用于画直线), '笔刷(用于绘图和填充),位图(用于屏幕的拷贝或滚动),调色板(用于定义可用的颜色集),剪裁区(用于剪裁和其他操作),路径(用 '于绘图和画图操作)。设备环境函数用于对设备环境进行创建、删除或获取信息 h = WindowFromPoint(lX, lY) '取得点所在控件的句柄 hD = GetDC(h) ScreenToClient h, P r = GetPixel(hD, P.x, P.y) ReleaseDC h, hD Text1.Text = h Text2.Text = hD Text3.Text = Hex(r) Text3.BackColor = r Dim WindowText As String, ClassName As String WindowText = String(64, 0) GetWindowText Text1.Text, WindowText, Len(WindowText) ClassName = String(64, 0) GetClassName Text1.Text, ClassName, 64 Text4.Text = Left(WindowText, InStr(1, WindowText, vbNullChar) - 1) Text5.Text = Left(ClassName, InStr(1, ClassName, vbNullChar) - 1) End Sub
form2代码:form2只有一个listview1控件
Private Sub ListView1_MouseUp(Button As Integer, Shift As Integer, x As Single, y As Single) If Trim(ListView1.SelectedItem.ListSubItems(2).Text) = "可用" Then Form3.tenable = False Form3.tdisable = True Else Form3.tenable = True Form3.tdisable = False End If If Trim(ListView1.SelectedItem.ListSubItems(3).Text) = "可见" Then Form3.tshow = False Form3.thide = True Else Form3.tshow = True Form3.thide = False End If If Button And 2 Then PopupMenu Form3.tedit End Sub
form3是菜单,无控件,菜单内容请看代码:
