If the process opening the file did not specify any sharing options, you cannot access it.

You should specify GENERIC_READ and FILE_SHARE_READ | FILE_SHARE_WRITE when openign the file.

What part of the computation do you want to know about? Do you have some code that is not working correctly? Is it too much to ask your instructor for some detailed instructions? Some will give you a few extra morsals that were not previously given in class (assuming you've at least bothered), while others will tell you to find the missing pieces on your own. Conspiring with classmates is also an option.

Help people!

I have just upgraded (still not really sure if it is an upgrade) to Visual Studio .NET

Using Visual C++ I have a library that needs to be linked to my app from the directory it was built in dependant on whether I am compiling for the debug or release version. So I have added the path to Tool/Options/VC++Directories/Library Files with the $(ConfigurationName) macro on the end. But it seems to make no difference, I can only get it to work if I put in the complete path.

Is this the correct macro? Or any tips?

Regards,
Kevin.

Add the appropriate directory to each configuration using the project property pages.

Using the project properties dialog box, navigate to linker->general->additional library directories. Add the directory for the appropriate folder, then change the configuration and add the other folder.

The ($ConfigurationName) macro may even be usable for 'all configurations'

C++ and ISAPI FILTER

I'm developping an ISAPI FILTER and I would like to know why this code for the event OnAuthComplete is not working; I have already declared the method and caught the notification (SF_NOTIFY_AUTH_COMPLETE: dwRet = OnAuthComplete(pfc, (PHTTP_FILTER_AUTH_COMPLETE_INFO))pvNotification); :

static DWORD OnAuthComplete(PHTTP_FILTER_CONTEXT pfc, PHTTP_FILTER_AUTH_COMPLETE_INFO pAuthCompInfo)
{
HANDLE TokenHandle = (HANDLE)1;
DWORD dwLen = 0;
PTOKEN_USER pTokenUser = NULL;
DWORD dwErr;
char name[MAX_NAME], domain[MAX_NAME];

// Get user token.
if ( pAuthCompInfo->GetUserToken(pfc,&TokenHandle) )
{
// Get token information size.
if ( !GetTokenInformation
(TokenHandle,TokenUser,NULL,dwLen,&dwLen) )
{
dwErr = GetLastError();
if ( ERROR_INSUFFICIENT_BUFFER == dwErr )
{
// Alocate buffer for token information.
pTokenUser = (PTOKEN_USER)GlobalAlloc(GPTR,dwLen);
dwErr = S_OK;
}
}

// Now get the actual token information.
if ( dwErr != S_OK ||
!GetTokenInformation(TokenHandle, TokenUser,pTokenUser,dwLen,&dwLen) )
{
// Error …
}
else // We have the token information in hand.
{
// Extract from the token information - the SID.
SID *pSid = (SID *)pTokenUser->User.Sid;
DWORD dwNLen = MAX_NAME, dwDLen = MAX_NAME;
SID_NAME_USE eUse;

// Get the user name and the domain from the SID.
if (!LookupAccountSid(NULL,pSid,name,&dwNLen,domain,&dwDLen,&eUse) )
{
// Error …
}
else
{
// name buffer contains user name.
// domain buffer contains user domain.
}
}
}

if (*name != NULL)
return WriteIntoFile(pfc, "OnAuthComplete: User name:" + *name);
else
return WriteIntoFile(pfc, "Evento OnAuthComplete: ");
}

WriteIntoFile is a method that write into a file and I have already tested it and it works well.

How can write a cookie from vc++ without ATL or MFC?

Yes, but I must use the ATL COM!
And without ATL? An application .exe that write a cookie.
No asp, php, cgi, perl....

These two statements contradict each other.

Did you even look at the code in the MSDN article Q241492, specifically step 6? That's C++ code that can be used with or without ATL.

Using CSocket, how to identify whether the server is still connecting.

Create a new EXE using the code in step 6. But if you aren't going to be using the code on an IIS machine, it's pretty pointless.

Exe file does not work

I have converted an old Visual C++ 6.0 into a Visual Net project.
After some reprogramming the program works fine when it is
beeing started from inside .NET (Ctrl + F5)
However when I try to start it using the exe file created by
.NET it will not start. The exe tries to start and uses almost
100% of the available CPU power, but then it only hangs and
the GUI never appears.
I tried to start the exe files on several different computers
and the same error occurs on all of them.
Anyone who have had this problem and know how to solve it?

Hi everybody,
i need to import a library file(winmm.lib) into my project using VC++.NET. The way to do that is so different from VC++ 6.0. Does anyone know how to do?
Thanks in advance.

HENDRIK R10-May-04 2:57

10-May-04 2:57

how about
#pragma comment(lib, "winmm.lib") ?

that should work on both 6.0 and .NET

you need to announce the whole path to your library file inside the pragma comment instruction ...
