Using POCO in MFC Applications

[guenter]

Just because this turns up occasionally: if you're using POCO in a MFC application, make sure to always include the MFC headers before POCO headers. Otherwise you may get the following error message:

Code: Select all

fatal error C1189: #error: WINDOWS.H already included.  MFC apps must not #include <windows.h>


And another tip: if your application uses Unicode, remember that POCO uses UTF-8 encoding (unless specifically disabled when building POCO) for filenames and other strings obtained from or passed to the OS. To convert such an UTF-8 encoded std::string into a UTF-16 encoded std::wstring, which can then be used in GUI code, use Poco::UnicodeConverter.
