Question

I try to compile this code with Windows 8 SDK :

typedef struct {
    enum { red, blue, green } eColor;
    /* other params here */
} StMyStruct;

void Myfunction(StMyStruct *pst) 
{
    if (pst->eColor==StMyStruct.red) {
        /* some code here */
    }

}

But I get this error on line if pst->eColor==StMyStruct.red :

error C2275: ‘StMyStruct’ : illegal use of this type as an expression

Any idea how to fix it ?

I compile this code successfully with Windows SDK 7, error happen only with Windows 8 SDK.

Try StMyStruct::red.

Also, you don’t need the typedef, that is mainly used when developing C — in C++, you can refer to a struct and class name directly.
