在打字时我会用什么事件来计算字符？ [英] What event would I use to count characters WHILE typing?

问题描述

当用户输入文本框时，我需要显示他们输入的字符串的长度。我的代码是......


displayCountLabel.caption = len（me！fieldTheyAreTypingIn）


问题是我似乎无法查找用户连续输入时发生的事件。我试过keydown和keyup和keypress。所有这些都是在第一次出现时开火，但是当用户继续打字时它们不会继续射击。


有谁知道我怎么能这样做？


谢谢

Hi,

While the user is typing into a text box, I need to display the length of the string they are typing. My code is...

displayCountLabel.caption = len(me!fieldTheyAreTypingIn)

Problem is that I can''t seem to find an event that occurs while the user continuously types. I tried keydown and keyup and keypress. All of them fire on the first occurence but they do not keep firing as the user continues to type.

Does anyone know how I can do this?

Thanks
Adam

推荐答案

您必须使用文本框的更改事件。这将在名为 CharacterCountLabel的标签中显示字符数。

You have to use the Change event of your textbox. This displays the character count in a label named CharacterCountLabel.
