Hi,
Take a look at TransmitFile()[^] API.
The doc says this: This function uses the operating system's cache manager to retrieve the file data, and provides high-performance file data transfer over sockets.

As a beginner, socket programming using VC++ is usually not recommended. There are way too many issues that will come up that you have not grasped yet. Why such an ambitious project?

hi..
i am converting my project from vs-2003 to vs-2008..it is working properly in release
mode..but not in debug mode..i have checked all my settings...they are similar...
In the below two bolded commandline,i made the differences in italic to better understand
my settingd->linker->commandline looks like(in release mode):
/OUT:"./../../Production Releases/Phoenix32.exe" /INCREMENTAL /NOLOGO /LIBPATH:".\..\..\lib"
/LIBPATH:"..\..\sybase\lib" /MANIFEST /MANIFESTFILE:".\Release\Phoenix32.exe.intermediate.manifest"
/MANIFESTUAC:"level='asInvoker' uiAccess='false'" /NODEFAULTLIB:"libc.lib" /NODEFAULTLIB:"msvcrt.lib"
/NODEFAULTLIB:"msvcprt.lib"
/DEF:".\PHOENIX.DEF" /DELAYLOAD:"OleAcc.dll" /PDB:".\Release/Phoenix32.pdb" /MAP:".\Release/Phoenix32.map"
/SUBSYSTEM:WINDOWS /DYNAMICBASE:NO /ERRORREPORT:PROMPT winmm.lib libsybdb.lib IEngine.lib fwfip.lib fwstruct.lib
fwpip.lib fwpfg.lib dbl32.lib dom32.lib csdlib32.lib csdfw32.lib csdxtra32.lib oldnames.lib version.lib
"..\..\dom\lib\dom32d.lib" "..\..\dbl\lib\dbl32d.lib" "..\..\lib\fwfipd.lib"
"..\..\csdfw\lib\csdfw32d.lib" "..\..\lib\iengined.lib" "..\..\lib\fwpipd.lib" "..\..\lib\fwstructd.lib"
"..\..\lib\fwpfgd.lib" "..\..\csdlib\debug\csdlib32d.lib" "..\..\csdxtra\lib\csdxtra32d.lib" DelayImp.lib
But in debug mode it is looking like this:
/OUT:"Debug/Phoenix32.exe" /INCREMENTAL /NOLOGO /LIBPATH:".\..\..\lib" /LIBPATH:"..\..\sybase\lib"
/MANIFEST /MANIFESTFILE:".\Debug\Phoenix32.exe.intermediate.manifest" /MANIFESTUAC:"level='asInvoker'
uiAccess='false'" /NODEFAULTLIB:"libcd.lib" /NODEFAULTLIB:"msvcrtd.lib" /NODEFAULTLIB:"msvcprtd.lib"
/DEF:".\PHOENIX.DEF" /DELAYLOAD:"OleAcc.dll" /DEBUG /PDB:".\Debug/Phoenix32.pdb" /SUBSYSTEM:WINDOWS
/DYNAMICBASE:NO /ERRORREPORT:PROMPT winmm.lib libsybdb.lib IEngined.lib fwfipd.lib fwstructd.lib fwpipd.lib
fwpfgd.lib dbl32d.lib dom32d.lib csdlib32d.lib csdfw32d.lib csdxtra32d.lib oldnames.lib version.lib
"..\..\dom\lib\dom32d.lib""..\..\dbl\lib\dbl32d.lib" "..\..\csdfw\lib\csdfw32d.lib"
"..\..\csdlib\debug\csdlib32d.lib" "..\..\csdxtra\lib\csdxtra32d.lib" DelayImp.lib
But i have given every library through linker settings.......
can anybody suggest in this regard......

Would you care to explain what is not working?

There is no "Release Mode" until you get it to work under the debugger. Take a look at this excellent article: Debug vs Release[^] which explains the subtleties involved.

I think he probably means Release Configuration within Visual Studio. Or do I misunderstand what you are saying?

Never mind.
I thought he wasn't able to get the program work under debug mode and it crashed in the release mode.
[Add] There's this thing of what does "not working" mean when the OP says it. With my previous reply, I was thinking that the code compiles and links, but resultant executable will crash. But, now I'm thinking if he isn't able to get past the linker or something like that. You'll never be able to guess all the "not working" posts correctly. [/Add]

No, if you read his OP he says that it works in "Release mode" (I think NDEBUG may be a better term), but crashes, or does not link, in DEBUG mode. However he has not really explained his problem very well.

I think a reasonable translation would be "I have no idea what I'm doing, urgent plz".

I disagree. Debug configuration and debugger is a luxury not a necessity.

Interesting opinion. However, I think that the debugger is a necessity, and not a luxury.

Something is necessary if removing it means that the system it is part of is no longer usable. Removing integrated debugger from Visual Studio does not mean we cannot program anymore, hence it is not necessary. It just means that it will take longer (potentially) to find bugs in the code. Just look at linux, there are no good integrated debugging enviornemnts (comparable to VS) but it hasnt stopped people from creating some really cool software.
In my opinion, we are just too much used to integrated debuggger.

Yeah? I think that I'd do myself a favour and continue to think of the debugger to be an essential part of my day to day development.
Saurabh.Garg wrote: It just means that it will take longer (potentially) to find bugs in the code.
With 3000+ source files in a projects, I think that it would take "a bit" longer to locate bugs, leave alone fixing.
Saurabh.Garg wrote: In my opinion, we are just too much used to integrated debuggger.
Fair enough! Everyone is entitled to have an opinion. In my opinion, I need the debugger and I think that it plays a very crucial role in my daily development activities.

Yes debugger is crucial in development and I am not saying that I dont use it. I completely agree with you.
What prompted me to this dicussion was your reply to OP about there is no release mode until program works in debug mode. That implies it is a bad practice to not use a debugger during development. I think it is perfectly fine to work in release mode and swtich to debugger only when a bug needs to be fixed.

Again, *you* think that.
I think that it is imperfect to start working right away in release mode. The debug mode means a lot (it does a lot of work for you) and several bugs will go unnoticed in the release mode, which the debug mode is capable of detecting.
It is assumed that you have fixed all the bugs and that you are heading to optimise the program now, when you start to build in release mode. Please read the Debug vs Release article I pointed out earlier; it explains everything in great detail.

What is the linker complaining about? Multiple defined symbols or undefined symbols.

Hi, dear all,
I am working on a project in VC++ and inside it I will invoke a excel file which already xml schema mapping on it, now I can put value to specified cell protect/unprotect workbook, but I don't know how to use Workbook.XmlImport() method to import xml file data to the spreadsheet. How can I do it.

Hi all vc++ programmers,
I am migrating my project from vs-2003 to vs-2008... i am getting the following linking errors...Actually i have 10 .lib files out of which three .lib files are not getting linked..My application is working sucsessfully in release mode...but not working in debug mode... the errors are:
fwpipd.lib(Fwstbk.obj) : error LNK2019: unresolved external symbol "public: int __thiscall DomDebtInfo::HasBeenBilledForFee(class ATL::CStringT<char,class StrTraitMFC_DLL<char,class ATL::ChTraitsCRT<char> > > const &,class ATL::CStringT<char,class StrTraitMFC_DLL<char,class ATL::ChTraitsCRT<char> > > const &HasBeenBilledForFee@DomDebtInfo@@QAEHABV?$CStringT@DV?$StrTraitMFC_DLL@DV?$ChTraitsCRT@D@ATL@@@@@ATL@@0@Z) referenced in function "protected: virtual int __thiscall CFeeStBaseBkNotes::IsEligible(class DomObject &,class DomObject &IsEligible@CFeeStBaseBkNotes@@MAEHAAVDomObject@@0@Z

Like this i am getting 362 errors........
I have seen in one of the forums that i should wrap the .lib in a DLL and consume that from my application..but i dont get the point..can anybody suggest me about this..............
and please give me any suggestion to go further.....
tanks in advanceeee

Did you rebuild all your libraries in VS2008? It looks like an entrypoint name is not defined in one of the libraries, and it may just be that the library needs to be recompiled under the new version of the compier/linker.

Hi thanks for the reply,,,
Yes i have rebuild all the libraries in vs-2008.Actually i am trying my 2003 code with Vista compatiable.In my company i am taking a remote login to Vista machine where vs-2008 is installed..I am getting the .exe in release mode and not getting in degug mode...I am getting the specified errors...I am getting these errors because the corresponding libraries are not getting linked.

Well, you seem to have answered your own question. Get these libraries linked in to your exe file, and it should be OK.

Hi,I created a complete Explorer window, used a CMFCShellTreeCtrl object associated with a CMFCShellListCtrl object.
And now,i want to make the CMFCShellTreeCtrl to show the items about pdf only! i did this
writing:
void CExplorerListCtrl::OnLvnInsertitem(NMHDR *pNMHDR, LRESULT *pResult) //CExplorerListCtrl:public CMFCShellListCtrl
{
LPNMLISTVIEW pNMLV = reinterpret_cast<LPNMLISTVIEW>(pNMHDR);
// TODO:
CString currentFolder;
GetItemPath(currentFolder,pNMLV->iItem); //pNMLV->iItem is always 0
if (GetSuffix(currentFolder).MakeLower()!=_T("pdf")) //i'm sure GetSuffix(Cstring str) is right
{
DeleteItem(pNMLV->iTem);
}
*pResult = 0;
}
program is always broken off!
Best thanks!

I want to detect USB pen drive when it is inserted in the PC. My MFC project will list its contents(Files n directories) to allow user to move or copy them.
How to do THIS!
