C++ strange problem: cannot find function member in class

Question

This problem seems very simple but I cannot solve it no matter what I try...
I have the prototype in the class, there is no duplicate prototypes with the same name nor functions. Yet it can't find it.

Look at these screenshots to see what I mean

Here is the class where they are added in the header file

Here is where I try to use the thing where all the functions and variables pop out doesn't have it.

As you can see in that image the RemoveParticle function is in the same area as FindTargetEffect function yet it can find the RemoveParticle just fine, and FindTargetEffect it can't.

If you think it's the defines.. i commented them out and it still doesn't work

Here is the header class.

class CParticleEntityManager {
public:
    friend class CParticleEntity;
    friend class CParticleBundle;

    CParticleEntityManager();

        
    int                     AddParticleToTargetBone(const char *name, 
                                                    DWORD targetID, 
                                                    int effectBoneIndex, 
                                                    bool useEffectBoneRotation,

Answer 1

Problem solved.. I had the same exact header file in a subfolder.

effectEffect_Sprite

and I also had it in the root of the project.

and the root of the project headers were outdated.
