How to solve intellisense identifier undefined in MFC uArt? - c++

Question

I'm having trouble in fixing the errors in this MFC uArt code. Three intellisense is undefined even though I included some header files to the program.
This is the error code when I build and run the program.
ERROR

if (USBDevice->BulkOutEndPt)
{
USBDevice->BulkOutEndPt->XferData(sUart, OutPacketSize);
}
}
Does anyone have any idea what header files I've been missing to include with? cause when i declare char sUart[60] in the code there's an error and also on the strcpy method there seems to be an error in the pBuffer LPTSTR. Please help.

Answer 1

This is usually a sign that you're doing a Unicode build, where LPTSTR expands out to wchar_t *, and you're trying to mix it with non-Unicode strings (in your case a char array.
Instead define tmpUart as:
TCHAR tmpUart[60];
and use _tcscpy to copy the string. This way your code will compile in Unicode and non-Unicode builds.
