[RESOLVED] Call managed function from unmanaged function?

[high6]

I am trying

#pragma managed

String * GetWebsiteData(char * url)
{
	HttpWebRequest * req = (HttpWebRequest*)HttpWebRequest::Create(url);
	HttpWebResponse * resp = (HttpWebResponse*)req->GetResponse();
	StreamReader * sr = new StreamReader(resp->GetResponseStream());
	String * ret = sr->ReadToEnd();
	return ret;
}

#pragma unmanaged
void UnmanagedFunc()
{
	std::string str = GetWebsiteData("A");
}

How do you pass/return a string?

[high6]

Okay I resolved this, found tons of examples of passing/returning ints but not much on strings. (strings are the only problem class)

std::string MStr2UStr(String ^ str)
{
	IntPtr ptr = Marshal::StringToHGlobalAnsi(str);
	if (ptr != IntPtr::Zero)
	{
		std::string ret(reinterpret_cast<char*>(static_cast<void*>(ptr)));
		Marshal::FreeHGlobal(ptr);
		return ret;
	}
	return std::string();
}
std::string GetWebsiteData(std::string Surl)
{
	try
	{
		String ^ url = gcnew String(Surl.c_str());
		HttpWebRequest ^ req = (HttpWebRequest^)HttpWebRequest::Create(url);
		HttpWebResponse ^ resp = (HttpWebResponse^)req->GetResponse();
		StreamReader ^ sr = gcnew StreamReader(resp->GetResponseStream());
		String ^ ret = sr->ReadToEnd();
		return MStr2UStr(ret);
	}
	catch (Exception ^ ex)
	{
		return std::string();
	}
}

Usage:

std::string Site = "http://mysite.com";
std::string str = GetWebsiteData(Site);

I was a bit confused at first, but managed/unmanaged is cool. I can now use low level hooks with high level libraries.
