I can't remeber but I'm sure i read somewhere that if the byt4es transferred were zero the client has called close scoket - in our code we have the following
BOOL bRet = GetQueuedCompletionStatus(_hIOCompletionPort, &dwBytesTransfered, &dwCompletionKey, &pOverlapped, INFINITE);
// If an error occured ensure that we flag the socket as closed so that the cleansweep thread destroys any
// system resources associated with the thread; If we receive zero bytes in length the socket is being closed
// on the client side - as we don't care for data loss (caused by a shutdown?)
if( !bRet || !pOverlapped || dwBytesTransfered == 0 ) {
pSocketInfo->State = SocketInfo::SocketState::Closed;
continue;
}

Having looked on MSDN at:
http://support.microsoft.com/support/kb/articles/Q105/6/75.asp
and
http://support.microsoft.com/support/kb/articles/Q250/5/63.ASP
I am still no clearer as to how I can disable the first-chance exception notifications in the Output Window of VC6. The articles above talk about the 'Encompass Monitor' service, but this is not running on my NT4 SP6 machine and neither encmonitor.exe or monitor.exe are present on my hard drive.
I noticed that neither of these articles specify NT4 in their 'information is this article applies to...' header.
I use a third-party ActiveX control that causes first-chance exceptions like no tomorrow and I would dearly like to prevent these from appearing in my output window.
Can someone please assist as it's driving me up the wall.
Thankyou

How is it possible to retrieve the exact version
of the platform a program is running on?
Cheers.

Try this code:
OSVERSIONINFOEX osvi;
ZeroMemory(&osvi, sizeof(OSVERSIONINFOEX));
osvi.dwOSVersionInfoSize = sizeof(OSVERSIONINFOEX);
if( !(bOsVersionInfoEx = GetVersionEx ((OSVERSIONINFO *) &osvi)) )
{
// If OSVERSIONINFOEX doesn't work, try OSVERSIONINFO.
osvi.dwOSVersionInfoSize = sizeof (OSVERSIONINFO);
if (! GetVersionEx ( (OSVERSIONINFO *) &osvi) )
return UnSupported;
}

OSVERSIONINFOEX only works on Win 2K. If all you care about is the major/minor version, there's no need for an OSVERSIONINFOEX. The original OSVERSIONINFO will work fine.

Hi,
I am new to developing a debugger......At present i am more interested in developing a GUI for my debugger, i want this similar to the VC++ debugger. In VC++ IDE, we see a red circle when a breakpoint is set, howz is this done? Drawing a circle in the View? If itz drawing then how can we do this in a CRichEditView or a simple CView??
Howz VC++ making the entire first column of its Editor in a different color??
If anyone has ideas, please reply.
Thanks & Regards,
Aruna.

Create a view window, then create a EDIT control child window for the program text at offset (16,16) in the client area.
Now you have 16 pixel area on the top and left to draw anything you want.
That's just a simple solution, you should implement your own EDIT control replacement to display program with keywords color.
For a debugger, read John Robbins' book.

I'm developing some extract tools, and i need the DLLs of Winzip, Winrar, CAB etc.
At the best, it includes ZIP, UNZIP, PASSWORD handling,

Do you think you can help me? Thank you!

Hi,
I am trying to build a NT Service that uses CFileFind class in the main loop.
The service is working right, but the CFileFind ins't.
I wrote as below:
CFileFind finder;
finder.FindFile("\\\\MYSERVER\\D$\\SOMEDIR\\*.*");
It should work, but It doesn't.
I noticed that if I don't use UNC, like below, the function works fine.
CFileFind finder;
finder.FindFile("D:\\SOMEDIR\\*.*");
My problem is I'm not working locally. I need to find the files in another server on the network.
If I map a letter to access the other server, it also doesn't work.
I wrote a dialog based app in order to test the CFileFind class, and I worked very well, so I think the problem is the service.
Does anybody have some idea on how to solve it?
Thanks in advance,
Vinicius

You need to have your service log in to \\myserver first. The reason it's working with a dialog app is the app is running as you, and you are (I assume) logged in to that server and/or have a drive mapped to it.
If you need it working in a pinch, change the service to run as you.

Thanks for your posting.
I understood what you sad, however, I am running locally. MYSERVER is the machine that I am testing the service and D is its shared folder.
Any way, could you tell me how to make the service log on to another server?
I am not an expert in NT Services, I am just trying to solve a problem in the company I work.
Thanks,
Vinícius

Hi,
Your problem is that a service, by default, is logging on as "System", that account does not have access to other machines.
When you run a dialog based app, the app. connects to the server with your username/password, where the service uses the "Local System Username/Password".
You need set a username that the service uses to log on to the system, when you try to access services across a network. You can do that in ControlPanel/services under NT4, or in the "Computer Management" MMC Console under Win2k.

I'm new to C++ and I wanted to know how to do graphics in C++ is there any help any one can give me
|
|
|
|

Well, C++ is a language which defines a standard. This standard does *not* include graphics. One can program an ABS brake system in C++, and clearly it has no use for any sort of display.
In other words, you need to be more specific. If you want to program graphics under Windows, I know a bit about it ( I do it for a living, so I should  ) and would be glad to help. If not, ellucidate and hopefully someone who can help you will come to light.

wincap.obj : error LNK2005: "struct HWND__ * ghWndMain" (?ghWndMain@@3PAUHWND__@@A) already defined in dllinit.obj
dlgopen.obj : error LNK2001: unresolved external symbol "void * ghInst" (?ghInst@@3PAXA)
Debug/asfasasfas.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.
Can anyone tell me what is the error above?

The first error indicates that you have two objects that contain the same function definition. The second is an error that is caused by not correclty linking to the .lib file for the dll that contains this function.
Hope this helps!!

For the First error try doing a complete "rebuild" this will delete the .obj files from your build directory and rebuild them. Sometimes this works.

Oh ouch... yuck...
Well, you'll have to do a bit of searching here. The LNK2005 indicates that you have more than one definition of ghWndMain. See the docs on LNK2005 for ideas. ghWndMain is declared in HOOK.C and should be extern to other modules. BTW sometimes you can use the FORCE switch to override this, but not a great idea.
But hey - maybe all of this stems from the fact that you are trying to use the C++ compiler to compile the WINCAP C sample - or at least integrate into your code(?). If you are not using MFC and stuff, you might be better off using C - if there are only C files in your project, you'll see much different results.
hmmm... might need an extern HINSTANCE ghInst; in dlgopen.c...
BTW with C++, you might also need to use extern "C" HANDLE var; in certain places instead of just extern HANDLE var; - this will turn off the name mangling and might help.
Maybe someone else has experience with this sample and using / porting it to C++.

HWND ghWndMain = 0
Is the above statement correct?

HWND ghWndMain = 0
Is the above statement correct?
|
|
|
|
|
#pragma data_seg("._WINCAP")<br />
HWND ghWndMain = 0;
#pragma data_seg()
Sure - but looks like 16 bit code with that pragma... not to worry, though, should compile...
But the wincap sample is pretty dated - old 16 bit code. There should also be a DIBAPI project or makefile - can you compile that? You'll need it.
I think what you're trying to do is use the WINCAP sample source directly in a cpp based project, and thats gonna be a bit of a hack. Even though you're getting close. I don't have WINCAP.EXE, so don't know exactly what you're up against, and it makes it tough to help.

I need to enquire whether C complier can complier win32 api source code? If it does , will the resulting .exe ba able to be used in win98 as win98 is win32 ?
|

I encountered any 'funny' error on viewing the earlier error , i made one change to the code. The change is shown below :
#pragma data_seg("._WINCAP") //
HWND ghWndMain = 0 ; // Handle to main window -- used to post msgs
#pragma data_seg() //
IThe change is that i made the statement " HWND ghWndMain = 0 " a comment , therafter i was able to generate an exe . However when i click the exe i see this a windows which only show the background and no menu buttons can be seen.
