问题描述
大家好，我是这个论坛的新手，我控制一个键有问题。
我想解决的问题是：
1）假设我们在c＃应用程序中有一个表单并有一个标签。
2）I想使用箭头键来改变标签。但我想要的重要的是，如果我按下键并处理它，标签必须显示指定的文本，而我一直按下键。如果我按下并立即将其取回，标签文本必须返回其原始状态。
3）这只是一个问题的证明。我想在其他应用程序中使用此属性，在此之前，我必须知道并且可以正确使用该属性。
提前感谢..
我尝试过：
我试图使用KeyDown，KeyPress和KeyUp事件，但我不能采取我想要的。一旦我按下键并保持该状态，情况就是一样。但是，我按下后退，标签不会改变（如果我不按键，我希望标签返回其原始状态）。
Hello everyone, I am new at this forum and i have a problem by controlling a key.
The problem that i want to solve is that way :
1) Let's say we have a form in c# application and have a label.
2) I want to use arrow keys to change tha label. But the important thing that i want is,if i press the key and handle it, the label must show the specified text while i keep pressing the key. If i press and take it back immidiately, the label text must return its original state.
3) This is just a demonstration of a problem. I want to use this property in other application , before doing that, i have to know and can use the property in proper way.
Thanks in advance..
What I have tried:
I tried to use KeyDown, KeyPress and KeyUp events but i couldn't take what i want. Once i press the key and keep it that state, the situation is same.However, i take the pressing back ,the label does not change (I want the label to return its original state if i don't keep pressing the key).
