C3867：'_com_error :: Description'：非标准语法 使用“＆”创建指向成员的指针

Question

i want to catch exception while connecting to Database and I'm using try catch, i use pointer but anyway it gives me such kind of error. C3867 '_com_error::Description': non-standard syntax; use '&' to create a pointer to member C3867 '_com_error::Description': non-standard syntax; use '&' to create a pointer to member . also there is not red line on e.Description, it just gives me this massage in error list. What is solution? Thank you in advance.

try
{

}
catch (_com_error &e)
{
    printf(e.Description);
}

Answer 1

_com_error::Description is a function.

you need to use the ():

try 
{
}
catch (_com_error &e)
{
    printf(e.Description());
}

On a sidenote: Description() returns a _bstr_t, which might not work well with printf()...
