As a UI layout, in a small surface, I suggest a top combobox populated with categories
and a bottom checkedListbox having the same width and populated with the "selectable" items.
Of course you intercept the combobox selection change event and you refill the listbox with item
belonging to the new active category only.

Doesn't that "hide" the categories to the user ? i.e. force him to click on the combobox ?

Yes that's true. But as I understood, the role of categories is here to aid with the selection process only.
The combox can show something as long as the following (MSWord options=>customize) :

And there would be no problem.
If the space is really very very small, then you may need a " hierarchical checked combobox "
Good luck.

A couple of ideas from iTunes
- The 'Grid' view, when you have the 'Artists' view selected, shows a grid containing all the artists. Double-click on that and you get a list view of all the artist's tracks, grouped into albums.
- The list view in iTunes shows all tracks (that's almost 13000 for me). There is a 'Search' field, which acts as a filter - if I want to find tracks which have some link to the text 'camera', I type 'camera' into the search field and get two tracks; 'Distant Camera' by Neil Young and 'The Camera Eye' by Rush

After creating some thread, I want to keep track of them in a vector
(vector<boost::thread> ), but it fail.
So I need to use vector<boost::thread*>, but in this way, I have to free them manually.

What do you mean by "it fails" ?
I never used boost::thread before but if you are getting a compilation error, it probably means that the class do not allow to make copies of an instance (e.g. they made the assignement operator and copy constructor private).

Exactly right - just like IOstreams

Use a std::vector<boost::shared_ptr<boost::thread> >. That way you get a copyable object that manages its resources itself.
it makes a lot of sense for a thread object to be non-copyable[^] - just like it makes sense for an iostream to be non-copyable. When you have a link to a concept visible outside your program, you only want one object to manage it otherwise you could get contradictory scenarios happening, like one object killing the thread while another is trying to join the thread or something.

But when using pointer, this still will happen.
Maybe things should be synchonized, but it'll be inefficient.

No it won't - you'll be copying the pointer, not the object it refers to.

Really? I think not.

More than one pointers can do things than conflicts simultaneously in different threads.

Agree, it's good to keep it simple for the fundamental concept. It can be encapsulated as needed.

Or you can use boost::ptr_vector<boost::thread> and it will delete the pointers for you when it goes out of scope.
Of course, Stuart's solution with shared pointers will work as well and may be even safer.

Hi
I want to show a web page in an html dialog(CDHtmlDialog) that has proxy!
I know how to do it via CInternetSession (with SetOption() method), but how to do it here?
Thanks

The question is somehow not very clear, that's why -may be- you didn't receive a reply.
Do you mean that you want the CDHtmlDialog to navigate to your webpage via a given proxy ?
I fear that case that the class wouldn't be inheriting options directly from Internet Explorer, otherwise there should be a way how to access the attached Html engine and set it to use a proxy.
This is all what I can help with.
Good luck.

sorry if it's not clear
Yes I want the CDHtmlDialog to navigate to my webpage via a given proxy?
And I wanna set the proxy settings (address&port&username&password) via my code.
Also if I can call a url that has a proxy may be helpfull, for example an API or something!
thanks

I found out that CDHtmlDialog holds a pointer to the IWebBrowser2 interface which I suspect to inherit evrything from Internet Explorer application.
That case you must configure the proxy in Internet Explorer itself (Tools => Options => Connection settings => LAN settings) whether manually or "programmatically".

Hi All
i need to write some data in excel file.I user CBasicExcel but in this calss memory leak problem.There is any more class.
Thanks in advance

I didn't see any memory leaks in CBasicExcel. Chances are that you're misusing it.

Hi Subramanian
if you see in the article <pre>CBasicExcel</pre> FAQ then you have found too many question about Memory leak and LongFile.

|
|
where can I found documentation of that class in msdn

i think you should ask that question from author of CBasicExcel.
