Hi,
I have regitsred key under AllSystemObjects in registry for context menu. It is working fine for all files and folders But when I right click on .lnk file, my menu option is coming twice.
How can I restrict it to come once.

Pther,
I'll give you credit for persistence! I'm impressed you found a better registry key than '*' for your shortcut handler - I failed. Mind you, you weren't paying me for an answer...
I'd strongly recommend sysinternals regmon program for sorting out any issues with the registry.
Is you handler called twice? I'm guessing you still have the * key setup - so are you called once for the lnk file, and once for the file the lnk points to?
The debugger should help you. If I haven't already told you, Michael Dunn's excellent shell series has information on debugger extension handlers in its first (or second) article.
First find out *why* you're getting two calls, then worry about "fixing" it. Maybe you want to give slightly different menu optiosn if it's a lnk file? Check the path you're being given to make sure both times are the same? If they're not, filter on that... Etc.
Iain.

Hi,
I have a thread in my application having a pipe (Created in Blocking Mode) which waits for the client to write to it.
Once pipe is read the post a message with the read pointer casted to Wparam to the main appication and waits for the next read.
Now the problem Iam facing is that by the time the application process the message the pipe is again read , so the memory gets overwritten.
Can anyone let me know how to overcome this problem?

Don't overwrite your memory?
Seriously. You read from a pipe into a section of ram that you've allocated. Try allocating a fresh chunk each time, post a message to some other part of your process with the pointer to that memory as (eg) lParam, then delete the message in that part.
If you use a buffer allocated on the stack (ie, inline in your procedure), and then keep reading on top of it, then you've volunteered for your own problem.
I would also worry that if you're processing messages slower than they're arriving then you may get problems. If it's just the occasional one, and most are fast, then you're fine.
Iain.

I tried creating memory in heap and deleting in my message handler , but it throws exception as memory was created in different thread and iam trying to delete it in my main application .

OK, sounds like you have the right idea though.
I'd have to do a bit of research (ie, *you'll* have to do a bit of research), but there's more ways of dynamically allocating chunks of memory that new/delete. There's also alloc/free, GlobalAlloc/GlobalFree(?)(though that's over the top, and lastly but probably a goodie - CoGetMalloc/IMalloc.
All sorts of different ways, and I'm sure most are thread safe.
If you're doing this LOTS of timesm for a lonf time, then the memory churn could cause you problems. Are your packets a relatively constant length? You could keep a large array of them, mark them as free / in use, and so on, but that becomes very hard and only useful if you *really* have to.

Please help me get rid of the following Error.

You somehow managed to get the symbol name wrong. I manually de-mangled the symbol and came up with the following:
class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > message
pl_kode wrote: Logger.obj : error LNK2001: unresolved external symbol "class std::basic_string,class std::allocator > __cdecl log(class std::basic_string,class std::allocator >" (?l
og@@YA?AV?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@V12@@Z)
Again, the symbol name is wrong here, it should read as follows:
class std::basic_string<char,struct std::char_traits<char>,
class std::allocator<char> > __cdecl log(class std::basic_string<char,
struct std::char_traits<char>,class std::allocator<char> > )

I have left with these errors when compiling my code:
"MyBrowser.obj : error LNK2019: unresolved external symbol __imp___stricoll referenced in function "int __cdecl b_compare(struct b_sort_s *,struct b_sort_s *)" (?b_compare@@YAHPAUb_sort_s@@0@Z)
MyBrowser.obj : error LNK2019: unresolved external symbol __imp__div referenced in function "public: virtual void __thiscall CMyBrowser:SurprisenPrint(class CDC *,struct CPrintInfo *)" (?OnPrint@CMyBrowser@@UAEXPAVCDC@@PAUCPrintInfo@@@Z)
MyBrowser.obj : error LNK2019: unresolved external symbol __imp__atof referenced in function "public: class ATL::CStringT<char,class strtraitmfc_dll<char,class="" atl::chtraitscrt<char=""> > > __thiscall CMyBrowser::GetColumnCount(int,int)" (?GetColumnCount@CMyBrowser@@QAE?AV?$CStringT@DV?$StrTraitMFC_DLL@DV?$ChTraitsCRT@D@ATL@@@@@ATL@@HH@Z)"
So the problems are with '_stricoll', 'div' and 'atof' in my code, to be more specific:
- suma += atof(GetItemText(i,nCol));
- res=_stricoll( (char*)arg1->string[j], (char*)arg2->string[j] );
- div_t div_result = div( pInfo->m_nCurPage-1, m_PageHorz+1 );
I searched for this functions, but could not find solution.
My project is in VC++2008 MFC and is 'Multi-threaded Debug DLL (/MDd)'
Any idea on this?
Thanks!

Do you have the linker switch Ignore All Default Libraries (i.e. /NODEFAULTLIB) ON?

Can anyone please tell me how to resolve these linker errors?
1 . "Error 1 error LNK2001: unresolved external symbol _CLSID_MMCVersionInfo"
2 . "Error 2 error LNK2001: unresolved external symbol _IID_IMMCVersionInfo"
Thanks,

Thanks a millions.
but can you please explain that, actually when I was including "Mmc.lib" in "Project Settings"->Linker->"Additional Dependencies", this resolved the error related IID _MMCVersionInfo but it was creating another linker error i.e. "error LNK2005: "public: __thiscall AFX_MAINTAIN_STATE2::~AFX_MAINTAIN_STATE2(void)" (??1AFX_MAINTAIN_STATE2@@QAE@XZ) already defined in Mmc.lib(apimfc.obj) nafxcwd.lib"

what is your project type, do you include any ather lib explicitly, you include stdafx.h in the beginning of every file, can you post the full length link error.

yes there are many, such as

Rajkumar R wrote: you include stdafx.h in the beginning of every file
yes in many files stdafx.h is included.
I think that might be error due to explicitly including many libs, since including #pragma comment (lib, "Mmc.lib") will set the lib linking to the specific obj file but not to the complete project am I right?

no, that is just a linker option specified in code rather than in project settings, so that you can specify the lib in code of some include files so that the corresponding lib is linked when the header is include.

Do you really nead this, try in shared lib, I can able to reproduce the problem if i use MFC in static lib and link MMC.lib and use AFX_MANAGE_STATE() macro. I don't have time to dig into it now, just curious do you have used such macros in the dialog application. MFC in shared lib build successfully for me, try it.

For me too.

Yes, actually it's a setup of my company's product so that it must use MFC as a static library.
Dear Raj, so nice of your time and effort.

I am facing a problem in using bitblt(...) function, its returning value as 0 if I say ctrl+alt+del and unlock it back.
I guess we are not getting handle correctly what could be the reason??? In normal scenario it working fine.
Expecting favourable reply.

Ofcourse I know about GetLastError. Its giving error as Invalid Handle, but why is it giving when the desktop is in Inactive mode??? I have seen in google groups this happens only with Win-XP. Please let me know if you have any idea of it.
