VAX 1543, VS2005, WinXP
Find references is not allways works properly in files included in stdafx.h
Steps to reproduce:
1. Create a new win32 project in VS2005
2. Create cOther.h file into the project with this content:
#ifndef _OTHER_H
#define _OTHER_H
class cAdder {
int Apple;
};
class cOther {
public:
tArray <cAdder> Adders;
void Something(void);
};
#endif
---
3. Create cOther.cpp into the project with this content:
#include <stdafx.h>
#include "cOther.h"
void cOther::Something(void)
{
Adders.GetSize();
}
---
4. Create tArray.h into the project with this content:
#ifndef _TARRAY_H
#define _TARRAY_H
template <class T> class tArray {
public:
int GetSize(void)
{
return 0;
}
};
#endif
---
5. Go to GetSize() definition in tArray.h, and Do a Find References on it.
Only references in this file will appear.
In my project other references also appears but only from this file, and files which are NOT included in stdafx.h
If you go cOther.cpp and Do Find References on GetSize(), it can found itself (and any other references in this file if any). So symbol is recognised. Is something wrong with handling stdafx.h?

| I am seeing the same effect here, but I don't see where the reference to "stdafx.h" comes from. It is not referenced in these instructions, and on the surface does not seem to be relevant to this problem. |

Out of interest do you only see this problem with template classes?

Sorry, I forgot a step beforde step 5:
- put to the end of stdafx.h
#include "tArray.h"
#include "cOther.h"
---
So cOther now "sees" the tempalate class "tArray", so Find References should work.
>do you only see this problem with template classes?
Yes, only templates are broken. These templates are included in stdafx.h
>I don't see where the reference to "stdafx.h" comes from
Template member function callings are found in cpp files which are NOT included in the stdafx.h. But I cannot reproduce this behavior in this test project so far.  |

I found an exception from stdafx.h rule. So forget this theory... 
Some references found in a few other files also. But no exact pattern so far. But my example is a good starting point for debugging, isn't it?  |

1543: Find references and stdafx.h
