alllocate() is supposed to be a member function of your special allocator class, not a global function.

I'm trying to retrieve the Url of a new window for my BHO... I did what S.Rod. suggested (his code was in C#, I'm using C++/ATL)
case DISPID_NEWWINDOW2:
{
CComPtr<IDispatch> pDisp = NULL;
m_pBlankDlg = new CBlankDlg();
m_pBlankDlg->Create( NULL );
CComPtr<IUnknown> spUnk;
m_pBlankDlg->GetDlgControl( IDC_BROWSER, IID_IWebBrowser2, (void **) &spUnk );
CComQIPtr<IWebBrowser2> spWB = spUnk;
spWB->get_Application( &pDisp );
pDispParams->rgvarg[1].pdispVal = pDisp;
m_pBlankDlg->ShowWindow( SW_SHOW );
}
And in CBlankDlg :
class CBlankDlg :
public CAxDialogImpl<CBlankDlg>,
public IDispEventImpl<IDC_BROWSER,CBlankDlg>
{
...
BEGIN_SINK_MAP(CBlankDlg)
SINK_ENTRY(IDC_BROWSER, 250, BeforeNavigate2Browser)
END_SINK_MAP()
void __stdcall BeforeNavigate2Browser(LPDISPATCH pDisp, VARIANT* URL, VARIANT* Flags, VARIANT* TargetFrameName, VARIANT* PostData, VARIANT* Headers, BOOL* Cancel);
The BeforeNavigate2 event is never triggered... why?
thanks for your help!

Fixed it!
spWB->get_Application(&pIDispatch);
*(pDispParams->rgvarg[1].ppdispVal) = pIDispatch;

I got it to work by changing this line:
*(pDispParams->rgvarg[1].ppdispVal) = pIDispatch;
But this cancels the popup! What I want to do is to get the URL and let the popup show itself. Why won't it display?
void __stdcall CBlankDlg::BeforeNavigate2Browser(LPDISPATCH pDisp, VARIANT* URL, VARIANT* Flags, VARIANT* TargetFrameName, VARIANT* PostData, VARIANT* Headers, BOOL* Cancel)
{
CAtlString szUrl = *URL;
*Cancel = FALSE;
}

Why are you defining back_inserter and family in your program? They are already provided by the standard libary. Remove those definitions and the program will compile OK.

This is not the way of obtaining a reverse iterator to a container. std::iterator is meant to support developers writing their own reverse iterators, so forget about it if you're in user mode.
Check rbegin and rend to learn how to traverse a container in reverse order.

Use list<int>::reference instead of list<int>::reference_type.
Joaquín M López Muñoz

Thanks, Joaquín buddie!
I have tested your method, it works OK!
But why should I use list<int>::reference instead of
list<int>::reference_type?
George
|
|
|
|
|
Because list<int>::reference_type is not defined either in VC++ 6.0 or in the standard.

Hey Im new to STl,
I just want to know whether MFC and STL can be mixed in a project..
I have developed a MFC Dialog application..Now i want to use list Library but im getting undeclared identifier error..I have included <list.h> hfile too.
cheers,
Super

Yes, you can mix'em. This error must be due to some missing #include.

Or he might be forgetting the std:: prefix. (i.e. std::vector).

Hi, everyone!
When using stack in STL, I meet with the following trouble.
Here are the source codes and related error messages. How to
resolve the trouble? My IDE is VC6.0.

#include <iostream>
#include <vector>
#include <list>
#include <deque>
#include <stack>
using namespace std;

stack<list<int> > s2;
stack<deque<int> > s3;
s1.push(1); s1.push(5);
cout << s1.top() << endl;
s1.pop();
cout << s1.size() << endl;
s1.empty()? cout << "empty" : cout << "not empty";
return 0;
}

I presume you want to create stacks contining ints, based on vector, list or deque??? What you've actually created is a stack of vectors of ints (s1), a stack of lists of ints (s2) and a stack of deques of ints (s3). To create stacks of ints based on vectors, lists or deques, use
stack<int, vector<int> > s1;
stack<int, list<int> > s2;
stack<int, deque<int> > s3;

Hi again,
I'm using attributed C++/ATL to create a COM server - I've come across a little annoyance: if I implement an interface on a coclass, i.e. derive from the interface, voila! its in the typelib. I want to keep a few interfaces to myself - I've tried adding the [hidden] attribute to the interface declarations, but no luck. Any suggestions?

second typelib, that you use internaly, lets say with "#import" or just include output file from midl.exe

Hi all, I'm undertaking a project that will eventually be run as a DCOM server. I anticipate DCOM for Win98/Me will be involved, but right now what I need to know is whether I can create the app as a service with the ATL wizard and run it as a standard EXE on any Win98 box...?
Thanks for any help,
NB

Nope, 9x does not have services (at least not like the NT concept of services). The most you can do is have the EXE call RegisterServiceProcess(), that way the process will not be killed when the current user logs out.
