Like the message says, wsprintf() has been replaced with StringCbPrintf() and StringCchPrintf(). wsprintf() is deprecated and is considered unsafe. So are similar functions, such as lstrcpy(). Microsoft designed its newer Win32 SDK headers to intentionally fail with linker errors on such functions. In order to see that message in the first place, you obviously have the newer headers installed. So you should do what the message says and use StringCbPrintf() or StringCchPrintf() instead of wsprintf() from now on. Gambit

If you really want to call wsprintfW(), then you have to call it
explicitally rather than through the macro that you are currently
using, ie:
WCHAR wsz[256];
wsprintfW(wsz, L"FilterGraph %08x pid %08x", pUnkGraph,
GetCurrentProcessId());
