QuestionVC6.0 compiler error C2664 while using GUID Pin
Vaclav_Sal9-Dec-12 6:44
memberVaclav_Sal9-Dec-12 6:44 
I am in over my head again.
I am getting error C2664 and I did read the Tech note   ( something about ANSI improvement)   about it and frankly I just do not understand what is the problem and <b>how to fix it in VC6.0.</b>

Do I have to redefine the   GUID_DEVCLASS_COMPUTER?

The parameter GUID is defined in both functions as “const GUID*”

The API fails with this error C2664 and C_GetClassImgIndex compiles OK

error C2664: 'SetupDiGetClassImageIndex' : cannot convert parameter 2 from 'const struct _GUID *' to 'struct _GUID *'
            Conversion loses qualifiers

Fails
b = SetupDiGetClassImageIndex(&m_imgList, &GUID_DEVCLASS_COMPUTER, &nRootImg);

OK
int n = C_GetClassImgIndex(&GUID_DEVCLASS_COMPUTER);

Any help would be greatly appreciated.
Cheers
Vaclav
