我想就是只要在“示例编辑框”中打上的字中有“姓名”(或者是身高体重)两个字,然后点击“查询”下面的编辑框中就会出现某个人的名字(或者身高体重),如果输入其他的我没有编写的进程序的问题点击查询就会出现“无法识别”的字样,所以button3里面的程序应该怎么写呢,求助大神!

I don’t know if my understanding is correct:
If you enter the name: Laowang, click the query to display Laowang
If you enter the increase: 170, click the query to display 170
If you If xxx is entered, the unrecognized string
will be displayed. If so, the code is as follows for reference only:

CString    strInput,strOutput;  //第一个字符串表示输入,后面一个表示下面的输出
int        nPOS = 0;

strOutput.Format(_T("无法识别字符串"));
nPOS = strInput.find(_T("姓名:"));   //也可以是 "姓名"不过要注意后面删除的时候要多加一位
if (nPOS != -1) {
    strOutput = strInput;
    strOutput.delete(0,nPos+1);
} else {
    nPOS = strInput.find(_T("身高:"));
    if (nPOS != -1) { 
        strOutput = strInput;
        strOutput.delete(0,nPos+1);
    }
}
//更新显示


return;

In fact, this operation mainly involves the processing of strings. If it is a String, it can also be processed using regular matching in C++11.
