获取richtextbox控件中所选文本的位置.. [英] get the location of selected text in a richtextbox control..

问题描述

任何人都可以请给我一个代码来演示我们如何在richtextbox控件中找到当前所选文本（任何位置，中间，左或右）的位置??



i需要在具有某些同义词选项的位置显示列表框。列表框在应用程序启动时不可见。只有当用户从richtextbox中选择一个单词时，才能在当前所选文本位置显示列表框。

can anybody please provide me a code to demonstrate how we can locate the position of the currently selected text (any position, middle, left or right) in a richtextbox control??

i need to show a listbox at the position with some synonyms option. the listbox is invisible at start of application. only when user selects a word from richtextbox should the listbox be shown at the current selected text location.

本文 [ ^ ]可能会帮助您找到x，y点。如果没有，请尝试这些谷歌搜索结果。 [ ^ ]

This article[^] might help you find the x,y point. If not try these google results.[^]

你应该在发布之前尝试谷歌你的问题。

Dim intPosition as Integer = txtRichtextbox .SelectionStart





但听起来你只想要所选的文字：

Dim strSelectedText as String = txtRichtextbox.SelectedText

You should try to google your questions before posting.
Dim intPosition as Integer = txtRichtextbox.SelectionStart


but it sounds like you reall just want the selected text:
Dim strSelectedText as String = txtRichtextbox.SelectedText
