Why MFC? I am getting lots of Windows.h already included related error messages.
But if we can get IP Address in MFC then that will server my requirement.
Thanks

figure out why these errors are popping and resolve them. May be you are missing a library to link to or you didn't include a header file.
BTW what are the errors?
You need to google first, if you have "It's urgent please" mentioned in your question.

MFC doesn't have functionality covering IP address resolution - if it works, your C++ code is as good as anything.
Don't get too hung up about things being in MFC or not in MFC - MFC is, for the most part, a thin veneer over Win32 functions and, overall, has a very old fashioned design , a lot of which was constrained by the deficiencies of C++ compilers in use when MFC was developed.

Nothing in your code is C++.
PankajB wrote: return IPAdd;
You are potentially returning an uninitialized pointer.

Then use the same code.

MFC offers no such class.

Thanks for the code! I just had to add the library Ws2_32.lib and the header Windows.h, works perfectly! Thanks!

Yeah it works perfect. Thanks a lot for the code

Hello,
I get compiler error error C2327: 'CMyGridEdit::OnChar' .symbol' : is not a type name, static, or enumerator..
What's wrong at this declaration ?
I have following declaration in VC++ 6.0
<<<mygrid.cpp>>
BEGIN_MESSAGE_MAP(CMyGrid::CMyGridEdit, CEdit)
ON_WM_CHAR()
END_MESSAGE_MAP()
void CMyGrid::CMyGridEdit::OnChar(UINT nChar, UINT nRepCnt, UINT nFlags)
{
}
<<mygrid.h>>
{
class CMyGrid : public CMSHFlexGrid
..
class CMyGridEdit : public CEdit
{
afx_msg void OnChar(UINT nChar, UINT nRepCnt, UINT nFlags);
DECLARE_MESSAGE_MAP()
};
};
Thanks for helps. jr

That pattern works fine in VS2008, so the only thing I can presume is that one of the VC6 compiler's many many deficiencies is biting you.
I'd suggest you pre-process the C++ file (with CL /P) and see if anything looks untoward in the BEGIN_MESSAGE_MAP code after pre-processing (don't look for BEGIN_MESSAGE_MAP in the .i file you get out of the pre-processor - it won't be there - look for CMyGrid::CMyGridEdit::GetMessageMap instead.

The following is the code fragment which I used in my application,
CStringb csFilePath = _T("C:\\MyFolder\\");
if(csFilePath != "\\")
{
DWORD dwError = GetLastError();
}
And i am getting an error code of 122(The data area passed to a system call is too small) in VS2008.
But in VC6.0, there is no such problem, the error code i am getting is 0.The application is with UNICODE supported.
Please help me to find out the cause of this problem.
Thanks & Regards

this should probably be

Thanks for the quick response .But at the compilation time this code didnt shown any errors or warnings . Do have any idea ,why it had happened like this ?
Thanks & Regards

Because the CStringT == operator is overloaded to handle PCYSTR .

Possibly because that's the last value that was set (with SetLastError() ). In other words:
SomeWindowsFunctionThatFailsWithCode122();
CString csFilePath = _T("C:\\MyFolder\\");
if (csFilePath != _T("\\"))
{
DWORD dwError = GetLastError();
} If nothing calls SetLastError(0) , then its internal value will stay 122 .

Hi,
Have a quick question on Boost weak pointers. Hope this is the place to ask. I found the article
Smart Pointers to boost your
code[^]
and on the paragraph "cyclic references" in the code there is the line
<br />
child->myDad = dad;<br />
where does the dad come from? Can't seem to see it defined anywhere in the code.
Thanks for any information.
|
|
|
|
|
I think it's just a typo. Should be:
child->myDad = parent;
EDIT: You can download the sources just to be certain
|
|
|
|
|
Ha ha, yes I did think it should be parent.
Thanks!
|
|
|
|
|
Actually, if it was a typo then why does the diagram underneath refer to "dad" and the dad.reset() ? Surely that can't be a typo as well?
|
|
|
|
|
As I said before - you really should download the sources first. The code will probably clear things up
|
|
|
|
|
Why not post this message on that article rather than here?
Looking at the article, I think that's a typo - dad should be parent

|
|

Hmmm, if it was a typo to put "dad" instead of "parent", then is the diagram showing dad pointing to the CDad struct a mistake as well?
|
|
|
|
|
He probably used dad and son or boy throughout, then tried to remove the gender specificness as it could be seen as discriminatory?

Hmmm, thats confusing! I'll try and email the author (if thats possible) as it is a good article and I want to get my head round it.
Thanks !

You should go deeper with the debugger.

I already went deeper in the Debugger, i still could not fix the problem.
