Compiler Warning (level 1) C4920

enum enum member member=value already seen in enum enum as member=value

Remarks

If a .tlb that you pass to #import has the same symbol defined in two or more enums, this warning indicates that subsequent identical symbols are ignored and will be commented out in the .tlh file.

Example

Assuming a .tlb that contains:

library MyLib
{
    typedef enum {
        enumMember = 512
    } AProblem;

    typedef enum {
        enumMember = 1024
    } BProblem;
};

the following example generates C4920,

// C4920.cpp
// compile with: /W1
#import "t4920.tlb"   // C4920

int main() {
}
