This is the code I am running.

C++

void PrintBrowserInfo(IWebBrowser2 *pBrowser) {
	BSTR bstr;
 	pBrowser->get_LocationURL(&bstr);
	wprintf(L"  1 URL: %s\n\n", bstr);
	myfile <<"\n  1 URL: << bstr;
	/////////////////////////////////
	std::wstring wsURL;
	wsURL = bstr;
 	size_t DSlashLoc = wsURL.find(L"//");
 	if (DSlashLoc != wsURL.npos)
	{
		wsURL.erase(wsURL.begin(), wsURL.begin() + DSlashLoc + 6);
	}
	DSlashLoc = wsURL.find(L"/");
	if (DSlashLoc != wsURL.npos)
		wsURL.erase(DSlashLoc);
 	wprintf(L"\n   2 URL: %s\n\n", wsURL.c_str());
	myfile <<"\n   2 URL: << wsURL.c_str();
	///////////////////////////////////
	SysFreeString(bstr);
}

The probem is this...on the second set of wprint.
if a url is http://www.codeproject.com
I get
codeproject.com which is great.
however if a url is http://stackoverflow.com
I get
tackoverflow.com which is not so great.
How can I fix this?
Thnak you.

The issue is that you have DSlashLoc + 6 as the end offset. This will always remove the starting protocol and colon, the // and the next 4 characters.

C++

//First remove the http, https, ftp, ...
size_t DSlashLoc = wsURL.find(L"://");
if (DSlashLoc != wsURL.npos)
{
	wsURL.erase(wsURL.begin(), wsURL.begin() + DSlashLoc + 3);
}
//Now remove the www. if it exists, otherwise leave it alone
DSlashLoc = wsURL.find(L"www.");
if (DSlashLoc == 0)
{
	wsURL.erase(wsURL.begin(), wsURL.begin() + 4);
}
