it's a raw "picture" of the memory occupied by the object...

To detect memory leaks right?? How do we find memory has been leaked?

no, only to see how the memory is filled.

with tools like Visual Leak Detector[^]

Using MFC "Object dump" usually refers to an object that inherits from CObject.
Dumping an object means calling CObject::Dump( CDumpContext& ) on that object. The dump function will write relevant information to the dumping context (usually a debug window) about the object's state, memory usage and whatever the developer that created the object thought could be useful.
The object dumping technique is not unique for MFC-CObject-derived objects. It's really about having a base class with a virtual function that can be called during debug sessions.

I am planning to have installshield for VC++ 6.0 which comes along with VC++ 6.0 to install some of the binaries.
All these day, I had been using Installation batch file to create directories,and copying the respective file into the directories and manully making registry entries using .reg file.
I would like to know, is it OK to use Installshiled which comes with VC++ 6.0 or to use the latest Installshield product itself.
What way using the Latest Installshield product is beneficial compared to the version of the Installshield comes along with VC++ 6.0
Is it possible to make use custom action dll & coinstaller in Installshield with VC++ 6.0??
Thanks

you could also have a look at inno Setup[^] which is free, fast to start with and really good rated by most users...

We used the Installshield that came with VC++6 to do the (fairly simple) installation of our VC6 apps, and this worked well for many years. One issue that encouraged us to change was that the setup.exe file that comes with this installshield, and that the user runs do the installation, is a 16-bit app. This can lead to the embarrassing situation that if the user's computer is not configured correctly for 16-bit apps (and many XP boxes are not - particularly after installing service packs) then the user cannot install your 32-bit app as the 16-bit installation program won't run!
There many reports of this on the web, e.g.
http://unodocs.nmsu.edu/RoboDocs/WebHelp/jinitiator/ji_05.htm[^]

IMHO, I never like Installer created by Install Shield ...as it too big.. i always prefer.. what Tox has suggested !

InstallShield is a horrible product, and there are several free alternatives like NSIS and Inno Setup.

Hi all,
The other day I got a code snippet of MSDN, I know what it does and what it's used for.
But what I don't understand is, when I type my ip address in,
it states that I'm not connected and when I type in any ip the code states that I'm Connected.
struct in_addr BIN_IPV4_ADDR_LOOPBACK = {127, 0, 0, 1};
struct in6_addr BIN_IPV6_ADDR_LOOPBACK = { 0x0, 0x0,
0x0, 0x0,
0x0, 0x0,
0x0, 0x0,
0x0, 0x0,
0x0, 0x0,
0x0, 0x0,
0x0, 0x1 };
#define MAX_LOCAL_NAME_LEN 64
BOOL IsNetPresent();
void Print(TCHAR *pFormat, ...);
int _tmain (int argc, TCHAR* argv[])
{
WSADATA WSAData;
WSAStartup(MAKEWORD(2,2), &WSAData);
if (IsNetPresent())
Print(TEXT("Network Connection IS present"));
else
Print(TEXT("Network Connection is NOT present"));
WSACleanup();
getch();
return 0;
}
BOOL IsNetPresent()
{
BOOL bFoundLocalAddr = FALSE;
char szAddrASCII[MAX_LOCAL_NAME_LEN];
ADDRINFO AddrHints, *pAI, *pAddrInfo;
if(gethostname(szAddrASCII, MAX_LOCAL_NAME_LEN - 1))
{
Print(TEXT("Error getting local host name, error = %d"), WSAGetLastError());
return FALSE;
}
memset(&AddrHints, 0, sizeof(AddrHints));
AddrHints.ai_family = PF_UNSPEC;
AddrHints.ai_flags = AI_PASSIVE;
if(getaddrinfo(szAddrASCII, "10", &AddrHints, &pAddrInfo))
{
Print(TEXT("getaddrinfo(%hs) error %d"), szAddrASCII, WSAGetLastError());
return FALSE;
}
bFoundLocalAddr = TRUE;
for(pAI = pAddrInfo; pAI != NULL && bFoundLocalAddr; pAI = pAI->ai_next)
{
if(pAI->ai_family == PF_INET)
{
if(memcmp(&(((SOCKADDR_IN *)(pAI->ai_addr))->sin_addr), &BIN_IPV4_ADDR_LOOPBACK, sizeof(BIN_IPV4_ADDR_LOOPBACK)) == 0)
bFoundLocalAddr = FALSE;
}
else if(pAI->ai_family == PF_INET6)
{
if(memcmp(&(((SOCKADDR_IN6 *)(pAI->ai_addr))->sin6_addr), &BIN_IPV6_ADDR_LOOPBACK, sizeof(BIN_IPV6_ADDR_LOOPBACK)) == 0)
bFoundLocalAddr = FALSE;
}
}
freeaddrinfo(pAddrInfo);
return bFoundLocalAddr;
}
void
Print(
TCHAR *pFormat,
...)
{
va_list ArgList;
TCHAR Buffer[256];
va_start (ArgList, pFormat);
(void)StringCchPrintf(Buffer, 256, pFormat, ArgList);
#ifndef UNDER_CE
_putts(Buffer);
#else
OutputDebugString(Buffer);
#endif
va_end(ArgList);
}
Could anyone please give me some help, clearly I don't understand it correctly.
Many Thanks

Probably, code is working correct but some logic inside is messed,

Here, comparison betn host's ip address and BIN_IPV4_ADDR_LOOPBACK will return value 0. And in that case bFoundLocalAddr is assigned value FALSE.
So, its is returning wrong value.
So you are returning wrong value from IsNetPresent.

If I have a populated dataGrid in visual c++, how can I get values from the dataGrid without going to the underlying dataSet.
Is there a way to use dataGrid->currentRowIndex to reference the row and then return the value from a given column.
Thanks!!

I created a tabbed dialog (with 2 tabs) without property sheets. I created a menu on the main dialog that I want to associate with one of the tabs of the tabbed dialog. I want to convert temperature on the embedded dialog to a celsius value when selecting the option from the menu.
I have an error when using the SendMessage function. The commented statements are different ways I have attempted to send a message but they are incorrect. A pointer references each embedded dialog.
Following this function are excerpts from my code (main dialog file, embedded dialog file).
Does anyone have any suggestions?

This means that tabbed window you are talking about, is not considered as window, thats why ASSERT.
Trevy wrote: /* errorC2664: caanot convert parameter 1 from HWND to UINT */
//SendMessage(m_dPointer[0]->m_hWnd, WM_MENU_CELSIUS);
You need to modify this to,
::SendMessage(m_dPointer[0]->m_hWnd, WM_MENU_CELSIUS,0,0);
But, again it should be valid window..
p.s. Its better to divide problem in small sub problem. Nobody like to read such huge code, like me( posted without using <pre> tags).
