hey all,
thanks to all for responding to my questions so far and helping me learn MFC/VC++
I have one more on my way...
Iam using VC++6.0 and have implemented the serial communcation between PC and the serial device(RABBIT3000-an 8 bit microcontroller).
When I build the program, everythign goes fine. I can send and receive packets on both ends.
But when I try to send a packet to the Rabbit from PC more than once, my VC++ code breaks..saying "assert failed"
the failure is in line 304 of MFC/SRC/WINCORE.CPP
ASSERT(pWnd == NULL || pWnd->m_hWnd == hWnd);
what does this mean?
CAn anyone explain?
Thanks in advance.

It has probably nothing to do with the communication itself (more with the way you are handling the data, if you show that on a window or something). It is really difficult for us to give a solution. You have to track the problem yourself. The best way to do that is to use your debugger: press F5 and see where it crashes, you can the use the call stack to see which function in your code was called last. Then, you can set breakpoints and do step-by-step debugging in the code where there are problems.

hey there,
thanks for ur response.
Will try debugging.

When the assertion fires, click the Retry button. This *should* take you to line 304 of wincore.cpp. From there you can view the call stack.

hello..
sipxmngr::EventCallbackProc(SIPX_EVENT_CATEGORY category,void* pInfo,void* pUserData)
{
SIPX_CALLSTATE_INFO* pCallInfo = (SIPX_CALLSTATE_INFO*) pInfo ;
switch (category)
{
case EVENT_CATEGORY_CALLSTATE:
{
switch (pCallInfo->event)
{
case CALLSTATE_OFFERING:
error here sipxmngr::handleCallStateEvent(pCallInfo);
break ;
}
}
return true ;
}
int sipxmngr::handleCallStateEvent(SIPX_CALLSTATE_INFO* pCallInfo)
{
switch (pCallInfo->event)
{
case CALLSTATE_NEWCALL:
sipxmngr::handleNewCall(pCallInfo->hCall, pCallInfo->cause);
break ;
}
return 1;
}
plz tell me the solution.

U cant call a non-static function like this
<br />
sipxmngr::handleCallStateEvent(pCallInfo);<br />
U need to have an object of the class sipxmngr or make the second function static

The function. Which function ? The second function. Which one ?
Dude, post some code to explain your situation more in detail.
The only solution I can give you here is to make the second function static.

In the OnInitDialog function,
Add a member
HICON m_hIcon;
in the ctor or OnInitDialog, load the icon
m_hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME);
call SetIcon to set the Icon
SetIcon(m_hIcon, TRUE);
SetIcon(m_hIcon, FALSE);
It's over, now comile compile and run, you can see the icon

Hi I've a requirement to hook into the PrintDlg/StartDoc/EndDoc API's using a global hook to obtain information when the end user does a print from any application that has a File/Print interface.
Any ideas as to what might be the best way to do this ? I'm considering using APIHijack - A Library for easy DLL function hooking by Wade Brainerd (http://www.codeproject.com/dll/apihijack.asp[^])
Any ideas/suggestion would be welcome.

void CParseView::GetEmbeds()
{
IHTMLElement* pDocElem;
IHTMLElementCollection* pElemCollections;
IHTMLDocument2 * pHTMLDoc2 = NULL;
pHTMLDoc2 = (IHTMLDocument2*)(this->GetHtmlDocument());
pHTMLDoc2->get_all(&pElemCollections);
COleVariant varName;
varName = SysAllocString(L"OBJECT");
IDispatch* spDispEmbed;
VARIANT name;
name.vt = VT_I4;
pElemCollections->tags(varName, &spDispEmbed);
IHTMLElementCollection* spCollectEmbed;
spDispEmbed->QueryInterface(IID_IHTMLElementCollection, (void**)&spCollectEmbed);
if (spCollectEmbed)
{
long lLen;
spCollectEmbed->get_length(&lLen);
for (long i = 0; i < lLen; i++)
{
IDispatch* pItem;
name.lVal = i;
spCollectEmbed->item(NULL, name, &pItem);
IHTMLElement* spElement;
pItem->QueryInterface(IID_IHTMLElement, (void**)&spElement);
if(pItem)
pItem->Release();
if(spElement)
spElement->Release();
}
}
if(pHTMLDoc2)
pHTMLDoc2->Release();
}
use the code, I got the length:lLen=4;but I can only fetch the first two Items,when i=2,pItem got a NULL. How could this happen?

Maybe instead of
spCollectEmbed->item(NULL, name, &pItem);
you should use
spCollectEmbed->item(name, NULL, &pItem);
or
VARIANT v2; v2.vt = VT_I4; v2.lVal = 0;
spCollectEmbed->item(name, v2, &pItem);
I hope it helps.
