The class CBCGPProp is a standard class (delivered with BCGTool) and it seems like this:
class BCGCBPRODLLEXPORT CBCGPProp : public CObject
{
DECLARE_DYNAMIC(CBCGPProp)

friend class CBCGPPropList;

// Construction
public:
// Group constructor
CBCGPProp(const CString& strGroupName, DWORD_PTR dwData = 0,
BOOL bIsValueList = FALSE);

// Simple property
CBCGPProp(const CString& strName, const _variant_t& varValue,
LPCTSTR lpszDescr = NULL, DWORD_PTR dwData = 0,
LPCTSTR lpszEditMask = NULL, LPCTSTR lpszEditTemplate = NULL,
LPCTSTR lpszValidChars = NULL);

virtual ~CBCGPProp();

enum ClickArea
{
ClickExpandBox,
ClickName,
ClickValue,
ClickDescription
};

// Operations:
public:
int GetExpandedSubItems (BOOL bIncludeHidden = TRUE) const;
BOOL AddSubItem (CBCGPProp* pProp);
BOOL RemoveSubItem (CBCGPProp*& pProp, BOOL bDelete = TRUE);
.
.
.
public:
virtual BOOL OnEndEdit ();

virtual void OnClickButton (CPoint point);
virtual BOOL OnClickValue (UINT uiMsg, CPoint point);
virtual BOOL OnDblClick (CPoint point);

virtual void OnSelectCombo ();
virtual void OnCloseCombo();

virtual BOOL OnSetCursor () const;
virtual BOOL PushChar (UINT nChar); ...}

in my CSelBCGProp.cpp it seems like this :
BOOL CSelBCGProp::PushChar (UINT nChar)
{
nChar;
return true;
}
What i need is to know the character that the user enter it and make a treatment on it.

Sorry for the delayed response,

need vector of vectors to hold more than just a "pair"

b-rad31125-Mar-10 3:34

Hi everyone,

I'm currently using a vector of vectors (which includes a pair of objects), I declare it as:

vector< pair< vector< long double >,string > > vec;

the problem is, I really need a "triple" which I know doesn't exist, so does anyone know how I could add an additional variable such as an additional vector of integers into the mix, and if so, how I'd load and access the data?

I currently use the following to load data:

vec.push_back(pair< vector< long double >,string > (row_temp, header));

where row_temp is a vector of "long doubles" and "header" is a string.

and I use the following to access the data:

newvec[zz].first[yy]
newvec[zz].second.data()

where zz and yy are just integer variables based on the loop that I'm currently in.

The reason that I'm needed to treat so many items as a single object is that I perform some sorting and "unique" routines on the vectors in the end.

Thanks in advance!

create a 'triple' class to replace the 'pair'... ?

template <class T1, class T2, class T3> triple
{
    triple (const & T1 a, const & T2 b, const & T2 c)
    {
        first = a;
        second = b;
        third = c;
    }

.. etc..

    T1 first;
    T2 second;
    T3 third;
};

put it in a new .H file and #include it where you need to use it.

if i was going to do this, i'd find the source for std::pair, copy it, then modify it to add the 'third' member . that way, i'd be sure to get all the c-tors and operators that i'd need, without having to add them one-by-one as the compiler complains.

you can probably find some std::pair implementations on-line, otherwise search your Visual Studio include files for "struct pair", to find the one that ships with your version of VC++.

If you have a recent MS compiler, i would suggest using the tuple[^] class. Very easy to use and does exactly what you want.

Check for validity of IP address [modified]

Hello
I need the c code to perform the following task "Given an IP address, check for validity of IP address".

Suppose the ip address is 172.16.10.61. So it is a valid address. Here to check it by taking separately each byte and check the range( 0-255) ( for exapmle using strtok(ipaddress, ".") ).I work in a fedora Linux 11. Instead of using the strtok on ip address string any direct library function is there?

Thanking you,

Tools for reverse engineering

Hi,
I would like to know if there are some good tools available to get the reverse engineered diagrams given
a set of files under a legacy project that needs to be reused and refactored.
It would be great if someone categorizes into Freeware open sources ones and that which comes with a cost.

error LNK2005...already defined

While building my code in VS2008 I am getting a build error: error LNK2005...already defined in ....
1>Linking...
1>Main.obj : error LNK2005: "unsigned char * X1" (?X1@@3PAEA) already defined in BC.obj
1>Main.obj : error LNK2005: "char * X2" (?X2@@3PADA) already defined in BC.obj

1>Rs.obj : error LNK2005: "char * X2" (?X2@@3PADA) already defined in BC.obj

In my project I have three .h files:
1) Common_Definitions.h
unsigned char X1[16];
char X2[4];

struct xyz
{
UINT32 X3;
unsigned int X4[4];
long X5;
int X6;
int X7;
};

2) BC.h
3) RS.h

I have three .cpp files
1) Main.cpp
2) BC.cpp
3) RS.cpp

In Common_Definitions.h I have definitions/declarations which I want to be available in entire project, While BC.h and RS.h has corncenred variables.
I have included Common_Definitions.h in BC.h and RS.h.
#ifndef Common_Definitions_h
#define Common_Definitions_h
#include "Common_Definitions.h"
#endif

I have included BC.h and RS.h in their corresponding .cpp files.
I have included BC.h and RS.h also in Main.cpp

Now while building I get the linker error LNK2005.
How to resolve it?

Earlier when I had included Common_Definitions.h in BC.h and RS.h directly without ifndef.
#include "Common_Definitions.h"
then it was giving compilation error:
1>d:\...\common_deFINITIONS.h(18) : error C2086: 'unsigned char X1[16]' : redefinition
1> d:\...\common_deFINITIONS.h(18) : see declaration of 'X1'
1>d:\...\common_deFINITIONS.h(19) : error C2086: 'char X2[4]' : redefinition
1> d:\...\common_deFINITIONS.h(19) : see declaration of 'X2'
1>dd:\...\common_deFINITIONS.h(22) : error C2011: 'XYZ' : 'struct' type redefinition
1> d:\...\common_deFINITIONS.h(22) : see declaration of 'XYZ'

So to resolve that I have included Common_Definitions.h in BC.h and RS.h using ifndef.
#ifndef Common_Definitions_h
#define Common_Definitions_h
#include "Common_Definitions.h"
#endif
But this is leading to linker error.

Please let me know how to resolve this compiler and linker issue?

You should try to instance any objects
in the *.cpp file(s) only... Smile | :)

When you will want to share any defined variables by other files -
just use "extern" definition:

// file1.cpp
...
char* pchTest("test");
...
// file2.cpp
extern char* pchTest;
...

Thanks Eugen for the reply.
In my case I have one var X1 in a .h file.
I want to use this X1 in three other .cpp files, then how should I declare and define it?
