Answer 1

Just create a form whose 只需创建一个表格

form.TopMost=true

You may want to create a transparent form so that the form itself is invisible. 您可能希望创建透明表单，以便表单本身不可见。

You may even want to create a non-rectangular form . 您甚至可能想要创建一个非矩形的表单。

Answer 2

Sometimes overriding the OnBackgroundPaint event will produce fewer flickers. 有时重写OnBackgroundPaint事件会产生更少的闪烁。 You might want to try that. 你可能想尝试一下。

Otherwise, I don't know what your code is doing to cause the flickers in the first place. 否则，我不知道你的代码是做什么来引起闪烁的。
