USING .DLL FILE IN HTML AND JAVASCRIPT

Hi, I wrote the following class in C++ just to test:

#pragma once
#include <windows.h>
#include <stdio.h>
namespace Test1 {

public ref class Class1
{ public: void Web_Code()
{ DeleteFile("c:\\Test_Web.txt");
printf("Hello");
}
};
}
And built it. So I got Web_Test.dll
I uploaded to my web folder Web_Test.dll
And inserted html onto the web page:

<OBJECT id="control"
classid="http:Web_Test.dll#Test1.Class1">
</OBJECT>
<script language="javascript">
function doScript()
{
control.Web_Code();
}
</script>
<body onLoad="javascript:doScript();">

What it suppose to do is to delete a file on a hard drive and print "Hello" on a screen as a web page is
being opened.

But it does not work!
Can you tell me what is wrong here.
Thanks in advance, G.G.

Maybe path is incorrect, "c:\\Test_Web.txt". Try:

file:///c://Test_Web.txt

Plus, most *.dll's are called by an executable.

Deleting files from a hard drive using a web page rangs a lot of bells here. Viruses do that and you are probably going to have problems with anti-virus programs, firewalls and many security setting from user's computer which do not allow running executables like that.
