I looked at this great answer.

However as soon as I change the setup as following:

• create a DLL with a class called JulianDate


• put the visualiser inside its own project


• create a separate solution instantiating the class JulianDate

This does not seem to work anymore. As soon as I add the visualiser formatter for the class JulianDate, the visualiser stops working altogether for all classes. I tried copying all the DLL files in this folder but to no avail:

• C:Users\DocumentsVisual Studio 2013Visualizers

Here is the code sample for JulianDate.h which I put in its own dll.

#if defined(DATELIB_EXPORTS) // inside DLL

#   define DATELIB_API   __declspec(dllexport)

#else // outside DLL

#   define DATELIB_API   __declspec(dllimport)

#endif  // XYZLIBRARY_EXPORT





class DATELIB_API JulianDate {

public:

    JulianDate() : m_date(0) {}

    JulianDate(unsigned long dt) : m_date(dt) {}

    unsigned long get_date() { return m_date; }

private:

    unsigned long m_date;

};

Here is the updated code for the visualiser/formatter, just adding JulianDateFormatter seems to cause some issues in the visualiser:

#include "stdafx.h"

#include "JulianDate.h"



#include <iostream>

#include <windows.h>



#define ADDIN_API __declspec(dllexport)



typedef struct tagDEBUGHELPER

{

    DWORD dwVersion;

    HRESULT(WINAPI *ReadDebuggeeMemory)(struct tagDEBUGHELPER *pThis, DWORD dwAddr, DWORD nWant, VOID* pWhere, DWORD *nGot);

    // from here only when dwVersion >= 0x20000

    DWORDLONG(WINAPI *GetRealAddress)(struct tagDEBUGHELPER *pThis);

    HRESULT(WINAPI *ReadDebuggeeMemoryEx)(struct tagDEBUGHELPER *pThis, DWORDLONG qwAddr, DWORD nWant, VOID* pWhere, DWORD *nGot);

    int (WINAPI *GetProcessorType)(struct tagDEBUGHELPER *pThis);

} DEBUGHELPER;



typedef HRESULT(WINAPI *CUSTOMVIEWER)(DWORD dwAddress, DEBUGHELPER *pHelper, int nBase, BOOL bUniStrings, char *pResult, size_t max, DWORD reserved);



extern "C" ADDIN_API HRESULT MyClassFormatter(DWORD dwAddress, DEBUGHELPER *pHelper, int nBase, BOOL bUniStrings, char *pResult, size_t max, DWORD reserved);

extern "C" ADDIN_API HRESULT MyStructFormatter(DWORD dwAddress, DEBUGHELPER *pHelper, int nBase, BOOL bUniStrings, char *pResult, size_t max, DWORD reserved);

extern "C" ADDIN_API HRESULT JulianDateFormatter(DWORD dwAddress, DEBUGHELPER *pHelper, int nBase, BOOL bUniStrings, char *pResult, size_t max, DWORD reserved);



class MyClass

{

public:

    int publicInt;

};



struct MyStruct { int i; };



ADDIN_API HRESULT MyClassFormatter(DWORD dwAddress, DEBUGHELPER *pHelper, int nBase, BOOL bUniStrings, char *pResult, size_t max, DWORD reserved)

{

    MyClass c;

    DWORD nGot;

    pHelper->ReadDebuggeeMemory(pHelper, dwAddress, sizeof(MyClass), &c, &nGot);

    sprintf_s(pResult, max, "Dll MyClass: max=%d nGot=%d MyClass=%x publicInt=%d", max, nGot, dwAddress, c.publicInt);

    return S_OK;

}



ADDIN_API HRESULT MyStructFormatter(DWORD dwAddress, DEBUGHELPER *pHelper, int nBase, BOOL bUniStrings, char *pResult, size_t max, DWORD reserved)

{

    MyStruct s;

    DWORD nGot;

    pHelper->ReadDebuggeeMemory(pHelper, dwAddress, sizeof(MyStruct), &s, &nGot);

    sprintf_s(pResult, max, "Dll MyStruct: max=%d nGot=%d MyStruct=%x i=%d", max, nGot, dwAddress, s.i);

    return S_OK;

}



ADDIN_API HRESULT JulianDateFormatter(DWORD dwAddress, DEBUGHELPER *pHelper, int nBase, BOOL bUniStrings, char *pResult, size_t max, DWORD reserved)

{

    JulianDate s;

    DWORD nGot;

    pHelper->ReadDebuggeeMemory(pHelper, dwAddress, sizeof(JulianDate), &s, &nGot);

    sprintf_s(pResult, max, "Dll JulianDate: max=%d nGot=%d MyStruct=%x i=%d", max, nGot, dwAddress, s.get_date());

    return S_OK;

}

Here is the main I used to debug the visualiser:

#include "stdafx.h"



#include <iostream>

#include "JulianDate.h"



class MyClass

{

public:

    int publicInt;

};



struct MyStruct { int i; };



int _tmain(int argc, _TCHAR* argv)

{

    struct MyStruct s = { 1234 };

    std::cout << s.i << std::endl;

    MyClass *c = new MyClass;

    c->publicInt = 1234;

    std::cout << c->publicInt << std::endl;



    JulianDate d(20);



    return 0;

}

How can I figure what's going on ?
