<br>主题：请帮我看看这个richeditctrl的问题
<br>内容：一个richeditctrl类，内有text如下：<BR>LT = action<BR>NT = corrective action<BR><BR>LT = activities<BR><BR>LT = activity<BR>NT = audit<BR>NT = procedure<BR>NT = review<BR><BR>LT = assembler<BR>BT = supplier<BR><BR>LT = audit<BR>BT = activity<BR>BT = reviews<BR>NT = audit finding<BR>NT = audit report<BR><BR>LT = audit client<BR>BT = organization<BR>NT = audit client report<BR><BR>LT = audit client report<BR>BT = audit client<BR>NT = audit client report test<BR><BR>LT = audit client report test<BR>BT = audit client report<BR><BR>LT = audit finding<BR>BT = audit<BR><BR>LT = audit report<BR>BT = audit<BR><BR>LT = audit review<BR>BT = review<BR><BR>LT = audit team<BR>BT = auditor<BR>NT = audit team report<BR><BR>LT = audit team report<BR>BT = audit team<BR>......<BR><BR>输入字符串，如果LT=“输入字符串”就滚动到相应的位置。代码如下：<BR>int CRichEditProxy::ScrollToSelected(CString keyword,int currentline )<BR>{<BR>&nbsp;&nbsp;&nbsp;&nbsp;CString Line;<BR>&nbsp;&nbsp;&nbsp;&nbsp;char buffer[128];<BR>&nbsp;&nbsp;&nbsp;&nbsp;int linetojump;<BR>&nbsp;&nbsp;&nbsp;&nbsp;int totalLine=m_predit-&gt;GetLineCount();<BR>&nbsp;&nbsp;&nbsp;&nbsp;for (int i=0;i&lt;totalLine;i++)<BR>&nbsp;&nbsp;&nbsp;&nbsp;{<BR>&nbsp;&nbsp;&nbsp;&nbsp;<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;m_predit-&gt;GetLine(i,buffer);<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Line=buffer;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if (Line.Left(2)=="LT" &amp;&amp; Line.Find(keyword)!=-1)<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;linetojump=i-currentline;<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;m_predit-&gt;LineScroll(linetojump);<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;currentline=i;<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;break;<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}<BR>&nbsp;&nbsp;&nbsp;&nbsp;}<BR><BR><BR>&nbsp;&nbsp;&nbsp;&nbsp;<BR>&nbsp;&nbsp;&nbsp;&nbsp;return currentline;<BR>}<BR>现在的问题出在m_predit-&gt;GetLine(i,buffer)这句，每当读入空行（只有回车的行），下一行的返回值就不正确，请高手帮忙看看是怎么回事？<BR>

<br>内容：仔细看看MSDN哈，有这么两个地方：<BR>1）首先这个GetLine有俩原型，一个俩参数的，一个仨参数，你用的是俩参数的，MSDN如是说：The first word of the buffer must specify the maximum number of bytes that can be copied into the buffer，所以你这么直接GetLine(i, buffer)肯定是不对的。<BR>2）MSDN里还有这么一句：The copied line does not contain a terminating null character。说明啥呢，每循环一次你得把这个buffer清一次0，或者根据返回值就从buffer里读这么多个字节出来。<BR><BR>建议哈，一个是用GetLine(int nIndex, LPTSTR lpszBuffer, int nMaxLength)，一个是每循环一次都ZeroMemory一哈。逻辑上有没有其他错误俺就不看了哈

<br>内容：问题解决了，多谢了！<BR>不过开始我是碰到回车行下一行就读2遍，也可以解决问题（因为每行开头一般是N、B或L,ascii码肯定大于每行的长度，而空行首字‘\n’的ascii值是10，所以下一行一般读不完），现在我换成3参数的函数了，肯定不会出问题了。<BR>多谢多谢！<BR>还有，啥游戏可以看到走光啊？
