Print a GUID variable

Question

I have a GUID variable and I want to write inside a text file its value. GUID definition is:

typedef struct _GUID {          // size is 16
    DWORD Data1;
             


        

Answer 1

You can eliminate the need for special string allocations/deallocations by using StringFromGUID2()

GUID guid = ;
// note that OLECHAR is a typedef'd wchar_t
wchar_t szGUID[64] = {0};
StringFromGUID2(&guid, szGUID, 64);
