webbrowser加载问题。

[wxh850619]

一个做好的网页用IE浏览器浏览没有问题，但是在delphi中用webbrowser加载就有问题。报invalid floating point operation错误。等待高手解决。

When running floating point code, such as that found in Direct 3D, you will often get a series of floating point exceptions. Microsoft supporesses these exceptions by default, but we raise them. It is easy to turn this option off in both C++Builder and Delphi.

Here is how to turn them off in C++Builder:

#include float.h

__fastcall TForm1::TForm1(TComponent* Owner)
: TForm(Owner)
{
_control87(MCW_EM, MCW_EM);
}

Here is how to turn them off in Delphi:

const
MCW_EM = DWord($133f);
begin
Set8087CW(MCW_EM);
end;

这是官方解决方案

能说得具体点吗？

[lcgboy]

代码都上了还不具体？

const
MCW_EM = DWord($133f);

begin
Set8087CW(MCW_EM);
end;

看不明白？

[lcgboy]

意思就是说，这些异常很正常，垃圾微软不严谨，没有抛出这些异常，但是我们（boland）却要抛出这些异常。、
解决办法很简单，就是在你的程序中加入如下代码：
const
MCW_EM = DWord($133f);

begin
Set8087CW(MCW_EM);
end;
至于位置，任意位置就可以了，最好是在调用webbrowser之前。
