在vb.net中使用Tab按钮在RichTextBox中选择单词 [英] select words in a richtextbox with tab button in vb.net

问题描述

我想对我在vb.net中制作的免费的Microsoft字词处理器进行细微调整. 我希望能够使用Tab键在richtextbox中选择单词.就像文本是"hello codeproject成员"一样，当我将焦点放在richtextbox上并第一次按tab时，应选择"hello".然后，当我们再次按下选项卡时，应该选择codeproject，依此类推.

我该怎么做?

我想我们必须使用keydown事件，然后检查选项卡的键码.并且这些单词可以被视为由空格分隔.有帮助吗?

i want to do a small tweak with a free microsoft word processor i have made in vb.net
I want to be able to select words in richtextbox with tab button. Like if the text is "hello codeproject members" and when i put the focus on richtextbox and press tab first time "hello" should be selected. Then when we press tab again codeproject should be selected and so on.

how do i do that??

i suppose we have to use keydown event and then check for tab keycode. And the words could be seen as separated by spaces. Any help?

推荐答案

正如您所说，您需要处理KeyDown事件并捕获Tab的Key.但是，Tab键是用于将焦点设置到下一个选项卡索引控件的默认键.我认为，您需要为其余控件设置e.Handle = true或将IsTabStop = true设置.

使用，

As you said, you need to handle KeyDown event and capture Key of the Tab. But Tab key is a default key for setting focus to next tab indexed control. I think, you need to set e.Handle = true or set IsTabStop = true to rest of your controls.

Use,

richTextBox.Select(startIndex, length)

您需要使用字符串函数来操作startIndex并为每个单词加长.

You need to manipulate the startIndex and length each word using string functions.
