' 调用
Dim ptrHandle As IntPtr ' 外部程序的句柄
Dim intLeft As Integer, intTop As Integer ' 外部程序在窗体内的位置
Dim intWidth As Integer, intHeight As Integer ' 外部程序在窗体内的大小

' 获取外部程序的句柄
ptrHandle = FindWindow(vbNullString, "Adobe photoshop") ' 引号中是外部程序的标题名
' 嵌入当前窗体
SetParent(ptrHandle, Me.Handle)
' 设置外部程序在窗体内的位置和大小(省略)

' 移动到指定的位置
MoveWindow(ptrHandle.ToInt32, intLeft, intTop, intWidth, intHeight, 1)
