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;
}

Hi, everyone!
Here is a sample of the usage of inserter of STL.
When compiling it with VC6.0, some error occur.
I have added the source codes and related error
messages below.

}

front_insert_iterator<Container> front_inserter(Container& x) {
return front_insert_iterator<Container>(x);
}
template <class Container, class Iterator>
insert_iterator<Container> inserter(Container& x, Iterator i) {
return insert_iterator<Container>(x, Container::iterator(i));
}
int main()
{

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
Telefónica, Investigación y Desarrollo

|

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.
Source Codes:
--------
#include <iostream>
#include <vector>
#include <list>
#include <deque>
#include <stack>
using namespace std;
int main()
{

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.

Thanks Mike,
Will look into that. Since I posted this message I've decided that I'd definitely have to do some funky conditional compilation so that there was no need to link to StartServiceCtrlDispatcher() etc anyway.
Maybe using the new attributed ATL I can simply switch the [module] parameters... we'll see
Thanks again,

Use delete[] when freeing dynamically allocated arrays created like this:
int * p= new int[1024]; and delete for every other use of new. Rule of thumb: use brackets in delete if and only if brackets where used in the corresponding new.

Thanks, Joaquín buddies!
I can hardly imagine a case where I should use
delete without brackets.
Can you show me an example?
