Unicode Print Trouble

[DSTR3A]

I'm using windows, C++ and running a console app (multi-byte). The info is printing fine to the screen, however it is not printing to my log file correctly. Any help is appreciated. Thanks.

wprintf(L"\n   2 URL: %s\n\n", wsURL.c_str());
myfile << "\n   2 URL:\n\n" << wsURL.c_str();

wprint gives me 2 URL: cplusplus.com
myfile gives me 2 URL: 4214214214321322103302033

The full code....

void PrintBrowserInfo(IWebBrowser2 *pBrowser) {
	BSTR bstr;
 	pBrowser->get_LocationURL(&bstr);
	std::wstring wsURL;
	wsURL = bstr;
 	
	size_t DSlashLoc = wsURL.find(L"://");
	if (DSlashLoc != wsURL.npos)
		{
			wsURL.erase(wsURL.begin(), wsURL.begin() + DSlashLoc + 3);
		}
	DSlashLoc = wsURL.find(L"www.");
	if (DSlashLoc == 0)
		{
		wsURL.erase(wsURL.begin(), wsURL.begin() + 4);
		}
	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);
}

Is myfile of type std::wofstream? It should be.

[DSTR3A]

No it's not. I'm using ofstream everywhere else, it's just this one line that I need. Tried this...

char LogURL;
WideCharToMultiByte( CP_ACP,WC_COMPOSITECHECK, wsURL.c_str(), -1, LogURL, 0,  NULL, NULL); 
myfile << "\n   URL:" << LogURL;

However, I'm getting an error on LogURL. (char not compatible with LPSTR)

I see this thread marked as answered, so I guess you solved the problem already.

Just FYI, std::wofstream will automatically encode to UTF-8 (which is compatible with ANSI), so you shouldn't need to worry about that conversion.

As for your use of the WideCharToMultiByte() function, it is incorrect. Refer to http://msdn.microsoft.com/en-us/library/windows/desktop/dd374130(v=vs.85).aspx for complete details on how to call it.

In short, LogURL should be an LPSTR, not a single char, and it should point to a valid memory buffer. Normally you first do a call to WideCharToMultiByte() with a NULL buffer so the function tells you how much memory you need. Then you allocate the needed memory and call the function once more, this time with the valid buffer.
