建立磁性窗体,实现窗体的粘贴:

实现粘贴的难点在于什么时候进行这个操作，假设有两个窗体Form1和Form2，移动Form2向Form1靠近，当Form2与Form1的最近距离小于distance时粘贴在一起。显然，应该在移动Form2的过程中进行判断，问题是在程序的什么位置插入判断代码

-Establish a magnetic form, to achieve a form of paste: Paste realize the difficulty that when this operation, assuming that there are two forms Form1 and Form2, Form2 move closer to Form1, Form2 and paste when the closest distance is less than the distance Form1 together. Obviously, it should be judged in the process of moving Form2, the problem is to insert the code to determine at what point in the program
