    this->webBrowser1->Navigate("http://finance.yahoo.com/echarts?s="num".HK+Interactive#chart1:symbol="num".hk;range=1d;indicator=volume;charttype=line;crosshair=on;ohlcvalues=0;logscale=on;source=undefined");

哦，顺便说一下，这段代码来自 ，变量的名称是num。再次，我将欣赏任何帮助，如果可能的话。谢谢。

Oh, and by the way, this code is from a "Windows Forms Application" and the name of the variable is "num". Again, I would appreciate any help if possible. Thanks.

推荐答案

看起来你没有做任何事情来构建字符串。我从来没有做过托管C ++，但我认为你不能这样做：
http://finance.yahoo.com/echarts?s=num 并得到你想要的。在C＃中，你可以使用operator +：http://finance.yahoo.com/echarts?s=+ num ，或者使用StringBuilder或String.Format。我想象在托管C ++中有类似的东西。

It looks like you aren't doing anything to build the string. I've never done managed C++, but I assume you can't do this: "http://finance.yahoo.com/echarts?s="num and get what you want. In C#, you could just use operator+: "http://finance.yahoo.com/echarts?s=" + num, or use StringBuilder, or String.Format. I'd imagine there's something similar in managed C++.
