C＃winform：复选框，按钮，代码 [英] C# winform : checkbox, button, code

问题描述

Hye ..我的程序是关于，我检查复选框并在我点击按钮后运行回收站程序，但我在运行程序时遇到错误。我如何解决这个问题呢？



谢谢



我尝试过：

Hye..my program is about, i check the checkbox and run the recycle bin program after i click the button, but i'm having the error when run the program. How do i actually solve that problem ?

thanks

What I have tried:

private void Button2_Click(object sender, EventArgs e)
       {

           checkBox1.Checked = SHEmptyRecycleBin(IntPtr.Zero, null, RecycleFlag.SHERB_NOSOUND | RecycleFlag.SHERB_NOCONFIRMATION);


       }

推荐答案

SHEmptyRecycleBin return integer (int) value

如果成功清空回收站然后返回0

如果回收站已经空了，你点击按钮然后返回值，如 -2147418113



所以，你需要相应地更改代码true false选中/未选中复选框

if successfully empty Recycle Bin then return 0
and if Recycle Bin already empty and you fire button click then return value like -2147418113

so, you need to change code accordingly true false for check box checked/unchecked
