Hi I am trying to call a function of a class present in a MFC DLL from another component. If I am building the total workspace in DEBUG mode then I am going to the appropriate function which I am calling. But If i am building the workspace in RELEASE mode I am not going to the appropriate function, instead it is going to some other function.
I checked with the class pointer through which i am calling the method doesn't change any where but still I am facing the problem.
I need the help immediately.

Waiting for an early reply.
Thanks & Regards

This has to be because of memory allocation/deallocation problem. In debug mode, it is taken care of automatically, but in release mode, we may need to be careful about initializing variables, allocating space, deallocating space, etc. Can you do a debug session and post the code which fails?

{<br />
public: <br />
	DECLARE_DYNCREATE(CMyDialog)<br />
	CMyDialog();<br />
	~CMyDialog();<br />
	DECLARE_MESSAGE_MAP()<br />
<br />
};<br />
<br />
<br />
---------------------<br />
IMPLEMENT_DYNCREATE(CMyDialog, CColorDialog)<br />
<br />
BEGIN_MESSAGE_MAP(CMyDialog, CColorDialog)<br />
END_MESSAGE_MAP()<br />
<br />
CMyDialog::CMyDialog()<br />
{<br />
}<br />
CMyDialog::~CMyDialog()<br />
{<br />
}<br />

I think u dont need to derive a class from CColorDlg to give a back color

if he only want to do set color he can do it by defining a simple brush at OnCtlColor function. Why should we take unwanted services for our application.

I think he want to set back color for his dialog. actually the CColorDialog is used fo rcolor choosing purpose naaa? I think we can use it services to get teh color selected. no need to derive a new class.

im not sure whether me and he is talking about same problem Frown | :(

Hi all

I am working on an app that creates a wizard via the CPropertySheet.

I need to change the displayed pages depending on the answers to questions along the way.

I thought if i called OnWizardNext, and return the dailog identifier

it would work

LRESULT CMyPage2::OnWizardNext()
{
return IDD_PPAGE5;
}

but it doesnt, anyone any ideas ?

You are right and I don't find any problem in your code Frown | :-(

Just check if you had add the page corresponding to IDD_PPAGE5 before the property sheet is created.

The Module used by OCX is not found at the time of registering, mainly it is libaray file!

Hi all,

I need to copy a string which may contain NULL characters in between. I may run a loop but I just wanted to know if there is any other way to do this. Normal function like strcpy and all will stop reading after it encounters a NULL since it assumes end of string when it reads NULL.

NOTE: I am using plain C.

strncpy or memcpy should help.

strncpy will not work:

The strncpy function copies the initial count characters of strSource to strDest and returns strDest. If count is less than or equal to the length of strSource, a null character is not appended automatically to the copied string. If count is greater than the length of strSource, the destination string is padded with null characters up to length count.

char szSource[23] = {"Before\0After"};<br />
char szDest[23];<br />
<br />
ptr = memcpy(szDest,szSource,22);<br />
printf("%s %d",szDest,strlen(szDest));<br />

Hi, may i please request you to just try this code and comment on why memcpy is failing? Is it the way it goes or am I wrong somewhere? Can you suggest some workaround? Thanks for your time.
