Returns a string value to Excel
static CXlOper* RetString( const char* lpszFormat, ... ); static CXlOper* RetString( const wchar_t* lpszFormat, ... ); |
A string template, which may include tokens preceded by %, like printf.
The remaining arguments to the function will be substituted into the returned string, as in the standard C library function printf. Arguments of type CString should be cast to (const char*) or (const wchar_t*) as appropriate.
This function returns a pointer to some static memory containing a string.
This static function can be used to return a CXlOper result containing a string from an add-in function, instead of CXlOper::Ret().
For example:
if (input < 0) return CXlOper::RetString("#Error: input (%lf) must be >= 0", input);
