问题描述

推荐答案

查看Substring函数。

所有你需要的是 yourstring.Substring（0,50）;

Look into the Substring function.

All you need to to is yourstring.Substring(0, 50);

我已经解决了这个我自己使用以下代码：



Dim Bkdesc as String



Bkdesc = RsProdesc（概述 ）

Bkdesc = Bkdesc.Substring（0,200）

Dim LsI As Integer

LsI = Bkdesc.LastIndexOf（）

Bkdesc = Bkdesc.Substring（0，LsI）



谢谢你们所有人..

I have solved this myself by using following code:

Dim Bkdesc as String

Bkdesc = RsProdesc("Overview")
Bkdesc = Bkdesc.Substring(0,200)
Dim LsI As Integer
LsI = Bkdesc.LastIndexOf(" ")
Bkdesc = Bkdesc.Substring(0, LsI)

& Thanks all of you..

通常你会实现50个字符的限制从数据库中检索产品信息时。

由于您还没有告诉我们您使用的数据库系统，我们无法帮您完成此操作。



要在VB.NET中执行此操作，请查看左功能。

它可以让你显示一定数量的字符。

Usually you would implement the 50 character limitation when retrieving the product information from your database.
As you haven't told us what database system you are using, we can't help you do this.

To do this in VB.NET, have a look at the Left function.
It will enable you to display on a certain amount of characters.
