pdb ripper

Extracts UserDefinedTypes from pdb file and generates cpp code

Usage

Dia2Dump.exe -rip [flags] ... <input.pdb>
-printNamesOnly
-printCppProxy
-genCppFiles
-ii		: include internals
-it		: include templates
-s		: generate symbol information
-m		: generate meta information
-d		: include deps
-rd		: resolve/sort deps
-names		: select specific UDTs (-names "nameA;nameB;-excludeC")

How it works

Imagine some code compiled into test.exe / test.pdb

class Shape {
public:
   Shape(int newx, int newy);
   virtual ~Shape();
   int getX();
   int getY();
   void setX(int newx);
   void setY(int newy);
   void moveTo(int newx, int newy);
   void rMoveTo(int deltax, int deltay);
   virtual void draw();
private:
   int x;
   int y;
};

Shape::Shape(int newx, int newy) { moveTo(newx, newy); }
Shape::~Shape() {}
int Shape::getX() { return x; }
int Shape::getY() { return y; }
void Shape::setX(int newx) { x = newx; }
void Shape::setY(int newy) { y = newy; }
void Shape::moveTo(int newx, int newy) { setX(newx); setY(newy); }
void Shape::rMoveTo(int deltax, int deltay) { moveTo(getX() + deltax, getY() + deltay); }
void Shape::draw() {}

class Rectangle: public Shape {
public:
   Rectangle(int newx, int newy, int newwidth, int newheight);
   int getWidth();
   int getHeight();
   void setWidth(int newwidth);
   void setHeight(int newheight);
   void draw();
private:
   int width;
   int height;
};

Rectangle::Rectangle(int newx, int newy, int newwidth, int newheight): Shape(newx, newy) { setWidth(newwidth); setHeight(newheight); }
int Rectangle::getWidth() { return width; }
int Rectangle::getHeight() { return height; }
void Rectangle::setWidth(int newwidth) { width = newwidth; }
void Rectangle::setHeight(int newheight) { height = newheight; }
void Rectangle::draw() { printf("Rectangle %d %d %d %d\n", getX(), getY(), getWidth(), getHeight()); }

class Circle: public Shape {
public:
   Circle(int newx, int newy, int newradius);
   int getRadius();
   void setRadius(int newradius);
   void draw();
private:
   int radius;
};

Circle::Circle(int newx, int newy, int newradius): Shape(newx, newy) { setRadius(newradius); }
int Circle::getRadius() { return radius; }
void Circle::setRadius(int newradius) { radius = newradius; }
void Circle::draw() { printf("Circle %d %d %d\n", getX(), getY(), getRadius()); }

Invite the ripper to do some work:

Dia2Dump.exe -rip -printCppProxy -s -m -d -rd -names "Rectangle;Circle" test.pdb > gen.h

Inject into test.exe and do some manipulations:

template<typename T, typename ...Args>
static inline T* new_udt(Args&&... params) {
	T* obj = (T*)malloc(sizeof(T));
	obj->ctor(std::forward<Args>(params)...);
	return obj;
}

Circle* obj = new_udt<Circle>(0, 0, 10);
obj->draw();
