MSVC cannot find my Rectangle class

I'm trying to create a game in C++ using Allegro, and I created a simple Rectangle class, but it appears to somehow be out of scope in my main program, I have:

stdafx.h

 12    Vector2() { }
 13    Vector2(const Vector2&) { }
 14    Vector2(const float& x, const float& y) : X(x), Y(y) { }
 15    ~Vector2( ) { }
 16    Vector2 operator+(const Vector2& v);
 17    Vector2 operator-(const Vector2& v);
 18};
 19

 12    Rectangle(const Rectangle& r);
 13    Rectangle(const float& x,const float& y,const float& h,const float& w);
 14    ~Rectangle() { }

 25};
 26
 27
 28#endif

Main.cpp

#SelectExpand
 1#include "stdafx.h"

 4using namespace std;

 6// Other functions...

#SelectExpand
 147void myDraw(ALLEGRO_BITMAP* texture, Rectangle source, Rectangle dest, ALLEGRO_COLOR tint, Vector2 scale, float angle, int flags) //<-- This is where the error message points
 148{
 149    al_draw_tinted_scaled_rotated_bitmap_region(texture,
 150    source.x, source.y, source.w, source.h,
 151    tint,
 152    dest.x, dest.x, dest.w, dest.h,
 153    scale.X, scale.Y,
 154    angle, flags);
 155
 156    return;
 157}

Help?

The specific error I'm getting is:
main.cpp(147): error C2061: syntax error : identifier 'Rectangle'

Also relevant: 41 IntelliSense: function "Rectangle" is not a type name main.cpp 147

I've copied and pasted the code you have supplied into MSVS2012 Ultimate and it compiles fine. There may be something causing a problem somewhere else.

On another note, it's generally a bad idea to use double underscores in include guards (e.g., __VECTOR2_H). The use of two underscores in identifiers is reserved for the compiler's internal use according to the ANSI-C standard.

Somewhere Rectangle() is being included in your project. I'm guess allegro_primitives.h somewhere along the road #include <wingdi.h>?

Edit: It's allegro.h that's the culprit.

I thought I was wrong once, but I was mistaken.

Thanks, I renamed everything Rectangle in my code to MyRect and it compiled successfully (I really hate it when it's something stupid and simple like that). Now that that's settled, I just have to remember what I was doing when my world froze.

Thanks!
