C++ OutputDebugStringW with newline

Question

I want to attach a new line to the OutputDebugStringW.

OutputDebugStringW(Item.pItem);

pItem is a LPCWSTR, not a wstring, so I could not directly add new line by saying + "/n".

Can somebody help?

Just output the newline in a separate call to OutputDebugStringW:

OutputDebugStringW(Item.pItem);
OutputDebugStringW(L"\n");

If for some reason you only want to make a single call to OutputDebugStringW, build a string first:

std::wstringstream ss;
ss << Item.pItem << L"\n";
OutputDebugStringW(ss.str().c_str());

Ah, I tried that, but I used "/" instead of "\". Thank you very much. – tmighty Apr 01 '13 at 13:38
could you perhaps also tell me how to OutputDebugWString an int? I would like to say something like OutputDebugStringW(L"Counter: " + iCounter); – tmighty Apr 01 '13 at 13:40

@tmighty: Use a wstringstream as in my second example: `ss << L"Counter: " << iCounter;`. – RichieHindle Apr 01 '13 at 13:42

@tmighty, Or `std::to_wstring(iCounter).c_str()`. – chris Apr 01 '13 at 14:39
