你能发布，你在代码中做了什么，并解释了一点（你下次和之前发现的内容）。这样我们就能得到你需要的东西。

类似于InStr的存在：

函数InStrRev（StringCheck As String，StringMatch As String，[Start As Long = - 1]，[比较为VbCompareMethod = vbBinaryCompare]）长得好


它将按照名称建议反向搜索。设置开始按钮参数文本框的当前.SelStart。


示例（未经测试）：

展开 | 选择 | Wrap | 行号

Hi Everyone

Hi Everyone

Can you post, what you done in your code and explain little bit more (What you find next and previous). So that we can get what you need.

Similar to InStr exists:
Function InStrRev(StringCheck As String, StringMatch As String, [Start As Long = -1], [Compare As VbCompareMethod = vbBinaryCompare]) As Long

It will search in reverse direction as the name suggests. Set the "Start" parameter to the textbox''s current .SelStart.

Example (untested):

Expand|Select|Wrap|Line Numbers
