实现在PPT演示过程中-用鼠标拖动图片

实现在PPT演示过程中，用鼠标拖动图片1新建一个ppt空白文档。2点击菜单：“工具宏宏”，出现对话框。3对话框中“宏名”写：drop（其他也可以），再点“创建”，就进入代码模式。4“Sub drop() End Sub”，类似的三句全删掉。把下面的代码全拷贝进去。Option Explicit Declare Function GetKeyState Lib user32 (ByVal nVirtKey As Long) As IntegerPrivate Declare Function WindowFromPoint Lib user32 (ByVal xPoint As Long, ByVal yPoint As Long) As LongPrivate Declare Function GetWindowRect Lib user32 (ByVal hwnd As Long, lpRect As RECT) As LongPrivate Declare Function GetCursorPos Lib user32 (lpPoint As PointAPI) As LongPrivate Declare Function SetCursorPos Lib user32 (ByVal x As Long, ByVal y As Long) As LongPublic Declare Function MonitorFromPoint Lib user32.dll (ByVal x As Long, ByVal y As Long, ByVal dwFlags As Long) As LongPrivate Declare Function GetSystemMetrics Lib user32 (ByVal nIndex As Long) As Long Private Const SM_SCREENX = 0Private Const SM_SCREENY = 1Private Const sigProc = Drag & DropPublic Const VK_SHIFT = &H10Public Const VK_CTRL = &H11Public Const VK_ALT = &H12 Private Type PointAPI x As Long y As LongEnd Type Public Type RECT Left As Long Top As Long Right As Long Bottom As LongEnd Type Public mPoint As PointAPI, dPoint As PointAPIPublic ActiveShape As ShapeDim dragMode As BooleanDim dx As Double, dy As Double Sub DragandDrop(sh As Shape) dragMode = Not dragMode If dragMode Then Drag sh End Sub Private Sub Drag(sh As Shape)Dim i As Integer, sx As Integer, sy As IntegerDim mWnd As Long, WR As RECT dx = GetSystemMetrics(SM_SCREENX): dPoint.x = dxdy = GetSystemMetrics(SM_SCREENY): dPoint.y = dy GetCursorPos mPointWith ActivePresentation.SlideShowWindow mWnd = WindowFromPoint(mPoint.x, mPoint.y) GetWindowRect mWnd, WR sx = WR.Left sy = WR.Top dx = (WR.Right - WR.Left) / ActivePresentation.PageSetup.SlideWidth dy = (WR.Bottom - WR.Top) / ActivePresentation.PageSetup.SlideHeightEnd With If dx dy Then sx = sx + (dx - dy) * ActivePresentation.PageSetup.SlideWidth / 2 dx = dyEnd IfIf dy dx Then sy = sy + (dy - dx) * ActivePresentation.PageSetup.SlideHeight / 2 dy = dxEnd If While dragMode GetCursorPos mPoint sh.Left = (mPoint.x - sx) / dx - sh.Width / 2 sh.Top = (mPoint.y - sy) / dy - sh.Height / 2 DoEvents i = i + 1: If i
