定义光标在文本框中的哪一行 [英] defining on which line the cursor is in a textbox

问题描述

对于我的应用程序，我需要以下行为：当我按F4时光标

必须移动到我的多行中的下一行以0开头的文本框。


查找以0开头的行并不困难，但找到下一行

行更难。例如：如果我的光标在第200行，则必须

开始在第201行搜索，而不是在第1行。


任何人都有任何想法？


我想把光标放在我所依赖的留置权上也是我需要的东西，所以如果有人知道如何做到这一点...... :-)

Hi,

For my application I need the following behavior: When I press F4 the cursor
has to move to the next line in my multiline textbox which begins with "0".

Finding lines starting with 0 isn''t that difficult, but to find the next
line is more difficult. For exemple: if my cursor is on line 200, it has to
start searching on line 201, and not on line 1.

Anybody has any ideas?

I guess that posotioning the cursor on the lien I foudn is also something I
will need, so if somebody knows how to do that... :-)

Thansk a lot in advance,

Pieter

推荐答案

据我记忆，这可以在API级别完成。看一下

文本框消息（从EM_前缀开始），特别是EM_LINEFROMCHAR

和EM_LINEINDEX。

Hi,

As far as I remember, this can be done at the API level. Take a look at the
text box messages (starting with the EM_ prefix), especially EM_LINEFROMCHAR
and EM_LINEINDEX.

嗨彼得，

$ b你找不到

textbox.lines


有些东西（大致写在这里未经过测试，从未尝试过）

\\ \\\\\

for i as integer = 200 to textbox1.lines.length-1

if x ........... .....

next

////

我希望这有帮助吗？

Hi Pieter,

Did you look for
textbox.lines

Something as (roughly written here not tested and never tried)
\\\\
for i as integer = 200 to textbox1.lines.length-1
if x................
next
////
I hope this helps?

快速和脏：使用循环并循环遍历文本框'''Lines''

属性并总结行的长度（+行的长度

分隔符） 。然后使用重载版本的

设置位置文本框的''选择''方法。

Quick and dirty: Use a loop and loop through the textbox''s ''Lines''
property and sum up the length of the lines (+ the length of the line
separator). Then set the position by using the overloaded version of
the textbox''s ''Select'' method.
