Derive a class from CButton, handle those messages in this derived class and use it for your radio.
Something like this:

CReadOnlyRadio: public CButton
{
public:
  DECLARE_MESSAGE_MAP()
  void OnLButtonDown(UINT nFlags, CPoint point) { /*Nothing here on purpose*/ }
  void OnLButtonUp(UINT nFlags, CPoint point) { /*Nothing here on purpose*/ }
  void OnLButtonDblClk(UINT nFlags, CPoint point) { /*Nothing here on purpose*/ }
  void OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags) { /*Nothing here on purpose*/ }
  void OnKeyUp(UINT nChar, UINT nRepCnt, UINT nFlags) { /*Nothing here on purpose*/ }
  void OnChar(UINT nChar, UINT nRepCnt, UINT nFlags) { /*Nothing here on purpose*/ }
};
...
BEGIN_MESSAGE_MAP(CReadOnlyRadio, CButton)
  ON_WM_LBUTTONDOWN()
  ON_WM_LBUTTONUP()
  ON_WM_LBUTTONDBLCLK()
  ON_WM_KEYDOWN()
  ON_WM_KEYUP()
  ON_WM_CHAR()
END_MESSAGE_MAP()
...
class CMyFancyDialog: public CDialog
{
 ...
 DoDataExchange(CDataExchange* pDX);
 CReadOnlyRadio  m_ReadOnlyRadio;
 ...
};
...
void CMyFancyDialog::DoDataExchange(CDataExchange* pDX)
{
  CDialog::DoDataExchange(pDX);
  ...
  DDX_Control(pDX, IDC_READONLY_RADIO, m_ReadOnlyRadio);
  ...
}
...

Hope it is understandable...

The only issue is you probably don't want to declare the member variable in the constructor. That should be in the header file for the class or, in this case, where you have all of those empty methods.

Declare the variable in the constructor? What do you mean?

What I mean is you have :

CReadOnlyRadio  m_ReadOnlyRadio;

in the constructor of the dialog class.

class CMyFancyDialog: public CDialog
{
 ...
 DoDataExchange(CDataExchange* pDX);
 CReadOnlyRadio  m_ReadOnlyRadio;
 ...
};

-this is the ("pseudo"-)declaration of the class, not its constructor.

Hi,
I am using ProC code in my 64 bit application.

i am getting the following error while building it:

error LNK2001: unresolved external symbol sqlcxt

I have added extern"C" in sqlcxt definition.

extern "C"
{
	void sqlcxt (void **, unsigned int *,
		struct sqlexd *, const struct sqlcxp *);
	void sqlcx2t(void **, unsigned int *,
		struct sqlexd *, const struct sqlcxp *);
	void sqlbuft(void **, char *);
	void sqlgs2t(void **, char *);
	void sqlorat(void **, unsigned int *, void *);
}

Does any one has any idea why I am getting this? Frown | :(

What you're getting is a linker error.
This can be fixed by referencing the library in which sqlcxt etc. are implemented.

I am linking to orasql9.lib.

Can u tell me which library I have to link?

Actually this is working fine for 32 bit application.
But for 64 bit i am getting this error. Smile | :)

Please Help......

Make sure you're linking to the library in the 64-bit configuration.
Each configuration will have separate settings.
So you must have missed referencing the library for the 64-bit configuration.

Actually orasql9.lib is a sql file,which is present in the Oracle 9i client I have installed.

So for 64 bit I am not getting which lib file to link.

.LIB files are usually the same for 32-bit and 64-bit.
It's only the corresponding DLLs that are different.

So do i need to install oracle 9i client for 64 bit?

or is there any way to use 32 bit dll?

You will need to install the 64-bit client if there is one.
64-bit applications cannot load 32-bit DLLs and vice-versa.

There are a few C++ decompilers available, but it is highly unlikely that you will get the exact source back.
Most of the C++ compilers available today especially Visual C++ does heavy optimization on the code and so when you get back the code, it will be very different from the original.

However, here are a few links that may help you.

Hi,

I am using MS access database for storing values.
while retrieving records from a table sequentially by record set
first two records are coming sequentially
and then last record is coming again 3rd, 4th are coming.

what is the problem?

I am using record set class for retrieving values.
I am using MoveNext() function.

Re: Database problem

You can use an ORDER BY statement when fetching the records to arrange it in the order that you need.

You should never assume anything about the order of records in a record set unless you use ORDER BY as superman wrote. The order is unspecified and is affected by a lot of parameters like sql engine implementation, order of insertion, indexes, etc.

SELECT a, b FROM TableC ORDER BY a ASC;

Hi you all
I'm struggling with this for a week now:
I need template class ,which receives 2 template parameters:
a) T- data type
b) container<t*> - STL container ( vector or list ) – elements of container are of type T*

tContainer_t<T, vector<T*> > or
tContainer_t<T, list<T*> >

how can i define this class???
i think it should be something like this?

template <class T, container< T*> >
class tContainer_t
{	
public:
	tContainer_t(void);
	~tContainer_t(void);
};

can one help me please Confused | :confused:
