我有一个已加载到 Visual Studio 2005 中的 win32 项目.我希望能够将内容打印到 Visual Studio 输出窗口,但我终生无法弄清楚如何.我试过 'printf' 和 'cout <<'但我的消息顽固地没有打印出来.
I've got a win32 project that I've loaded into Visual Studio 2005. I'd like to be able to print things to the Visual Studio output window, but I can't for the life of me work out how. I've tried 'printf' and 'cout <<' but my messages stay stubbornly unprinted.
是否有某种特殊的方式可以打印到 Visual Studio 输出窗口?
Is there some sort of special way to print to the Visual Studio output window?
您可以使用 OutputDebugString.OutputDebugString 是一个宏,根据您的构建选项映射到 OutputDebugStringA(char const*) 或 OutputDebugStringW(wchar_t const*).在后一种情况下,您必须为该函数提供一个宽字符串.要创建宽字符文字,您可以使用 L 前缀:
You can use OutputDebugString. OutputDebugString is a macro that depending on your build options either maps to OutputDebugStringA(char const*) or OutputDebugStringW(wchar_t const*). In the later case you will have to supply a wide character string to the function. To create a wide character literal you can use the L prefix:
OutputDebugStringW(L"My output string.");
通常,您会像这样将宏版本与 _T 宏一起使用:
Normally you will use the macro version together with the _T macro like this:
OutputDebugString(_T("My output string."));
如果您的项目配置为为 UNICODE 构建,它将扩展为:
If you project is configured to build for UNICODE it will expand into:
OutputDebugStringW(L"My output string.");
如果您不是为 UNICODE 构建,它将扩展为:
If you are not building for UNICODE it will expand into:
OutputDebugStringA("My output string.");
