4. Use CPP DLL in ASP.NET Page

Hi,

I want to use a cpp dll in one of my page, I need to call 1-2 functions, 
pass value and get return. actually it is a key generator dll for my 
shareware. ASProtect to be very precise, they have not provided asp.net 
samples for it.

for this I first made a wrapper in VB6 activex dll, then in asp.net page 
added a COM reference. but this is not working I get a file not found error.

so what is the correct way to use a cpp dll in asp.net pages. ?

please help, thanks in advance. 

5. Unspecified error File: vsee\lib\path\cvapipath.cpp - Asp.Net

6. managed cpp question

using Managed CPP, I have a class, WriterNetworkSink, with a method,
GetHostURL like so

String* WriterNetWorkSink::GetHostURL()
{
     DWORD size;
    m_networkSinkWriter->GetHostURL( NULL, &size );

    WCHAR* url = new WCHAR[size];
    m_networkSinkWriter->GetHostURL( url, &size );

    return url;
}

"m_networkSinkWriter" is an underlying COM object that my WriterNetworkSink
object encapsulates.

All works fine. I can call the function from a C# app, and get the expected
result.

I'm just wondering if there is any cleanup I should be doing on the "url"
variable.

Thanks, Ron
