VC 2008 compiler errors [modified] - SOLVED

I'm trying to compile some code that uses _vsnprintf, and I'm getting errors from the compiler about :

1>regerror.c
1>c:\program files\microsoft visual studio 9.0\vc\include\stdio.h(358) : error C3163: '_vsnprintf': 
attributes inconsistent with previous declaration
1>        c:\program files\microsoft visual studio 9.0\vc\include\stdio.h(350) : 
see declaration of '_vsnprintf'

I have _CRT_SECURE_NO_DEPRECATE, _SCL_SECURE_NO_DEPRECATE, and _CRT_NON_CONFORMING_SWPRINTFS defined.

The code uses it like so:

va_init_list(args, (char* )fmt);
n = vsnprintf((char* )buf, bufsize, (char* )fmt, args);
va_end(args);

where "vsnprintf" is actually a macro defined as :

#define vsnprintf   _vsnprintf

To the best of my knowledge this has worked fine with *all* previous compilers MS C++ compilers, so I'm stumped at what to do here.

Bah!! Turns out there is now a vsnprintf function, so it's a non-issue - I just needed to comment the #define out for VC9 compilers.

backup network files - problem

sgeocla5-Dec-07 3:58

I am developing an application that is trying to backup (BackupRead, BackupWrite) a file from the network. The process has SE_RESTORE_NAME and SE_BACKUP_NAME privileges set. Creating the backup file is successful but I'm having problems restoring it. When I try to use GetFileAttributes on the folder in whitch I'm trying to restore the file, it fails and GetLastError returns ERROR_INTERNAL_ERROR (1359) for a network share with full access to everyone and returns ERROR_PATH_NOT_FOUND (3) if the share is mounted as a mapped drive. I also cannot create files from my program, but I can create them in windows explorer.
Are there more privileges that I need to set? Am I doing something wrong?
Please help

Hi All,

What I'm trying to do is implement in c++ a routine that loads another programs icon without loading that program. What api does windows explorer use to do it?

Any help would be greatly appreciated

Regards

Have you considered ExtractIcon()?

Grr - I knew there had to be a simple function.

not LoadIcon, not ExtractResource...

I started thinking about LoadLibrary, FindResource etc...

Then I sae you'd already replied with the perfect answer.

Sometimes "we" can be too clever for our own good.

I haven't tried it yet but I've looked at the api and I believe it to be what I was looking for.
I've been Googling all kinds of search criteria looking for this answer.... so many thanks for your help.

CInternetSession Problem

Hi,

I am writing an appliction which downloads MJPEG stream from IP camera. My application supports many IP cameras at a time. So i need to download several URL at a time from single instance. But the problem is when I add my fifth camera my application gets hanged. So is there any limit on how many URLs we can open using CInternetSession's OpenURL method? From my application I am able to open upto 4 URLs for one instance. For fifth URL my application give "timeout" exception.

Code:

CStdioFile* m_pFile[5];
CInternetSession m_inetSession[5];

for(int iIndex = 0; iIndex < 5; ++iIndex)
{
m_pFile[iIndex] = m_inetSession[iIndex].OpenURL (cstrUrl, 1, INTERNET_FLAG_TRANSFER_BINARY | INTERNET_FLAG_RELOAD);
.
.
}

Thanks in Advance.

Since CInternetSession class is a wrapper around InternetOpenUrl(), you could temporarily change your code to use InternetOpenUrl() instead. When/if it fails, you can call GetLastError() to find out why.

GetLastError() returns error code 12002.

From the docs:

ERROR_INTERNET_TIMEOUT

The request has timed out.

Are you sure the URL is valid?

Struct or class?

Hello everyone,

Multiplies is a struct, why MSDN said it is a class?

Because in C++ a struct and a class are quite similar. The difference is that structs give, by default, public public access to their members, while classes do the opposite (private access, by default, to their members).

learn your school lessons. in C++, a struct is a class (the only difference is that is defaults is members as public instead of private).

C++ recommands that use class only for its spirit.
struct in C++ is for compatibility with C.
However you can think class as a mentally concept, as a more common concpet, so either can be called a class as you like.

How to add a ComboBox to Browseinfo?

I want to custom a Browseinfo window.
For original Browseinfo only gets the address information, I also want to know which form user choose(xsl,xml,txt,ect) now.
So, I want to add a ComboBox on the Browseinfo window.

I tried, but always encountered error when I calculate the ComboBox's location.

Does anyone have a relative Demo ? (a simple one is better Poke tongue | ;-P

)
And welcome any idea.
Thanks a lot!

When i call the CDialog::OnOK(); function I get error :

How can I solve this error?

One possibility is deriving your dialog from CDialog

The other one is establishing it by yourself

//in header
//{{AFX_MSG(CDaishi)
virtual void OnOK();

//in cpp
void CDaishi::OnOK()
{
//do whatever you need
}

Forget about it. I didn't pay attention, you are not in MFC.
