How do I pass a string variable to MessageBox()?

[Keith Wilcox]

hello, I am having trouble finding the solution to printing the contents of a variable. Here is my code:

void OnSize(HWND hwnd, UINT flag, int width, int height)
{
	std::wstringstream ss (std::wstringstream::in | std::wstringstream::out);
	ss << flag;
	std::wstring myStr = ss.str();
	MessageBoxW(hwnd,myStr, L"Window Resized",NULL);
}

Note, I have #defined UNICODE at the beginning. The compiler tells me this for myStr.

std::wstring myStr
Error: No suitible conversion function from "std::wstring" to "LPCWSTR" exits

I would appreciate knowing what I'm not doing. =|

MessageBoxW(hwnd, myStr.c_str(), L"Window Resized", MB_OK);

Wow, that worked. Thanks.
