C#Winform控件问题

[sbc0519]

在form里定义两个控件，如picturebox1和picturebox2 我要让它们同时运动，每个有每个的运动方式（如picturebox1：x=sin t，y=t；picturebox2：x=t，y=480-t） 并用button1来控制picturebox1的停止运动，用button2来控制picturebox2的停止运动 请问大佬们该如何实现

多线程控制窗体，另有什么用吗

还请大师指教

[sbc0519]

我觉得很有用啊

首先这个控件不支持动态图像，除非你自己绘制坐标系和函数图像，重写它的onpaint方法或是用w p f

不是，这里的x、y为left与top

在线程里面加控制标记，button控制标记来暂停或什么的，轨迹自行设置，这里随意设的

自己绘制坐标系和函数图像，重写它的onpaint方法或是用w p f

[xiaozhao127]

添加一个timer控件,在函数体里对button控件的.Location属性(x,y)同时增减x,y的值，x,y到最大或最小时改变一下，反向操作(最好创建两个全局int变量来控制增减多少，反向时乘以-1方向就可以改变方向)，创建两个全局bool变量IsMove1和IsMove2在改变button控件时用来判断是否增减值;同时如果是true就把变量变false,反之则异然。
