*grin* Yes, Imran does ask the same questions over and over again and gives the impression that he has no idea how to search for things himself. In this case, I had just finished explaining that you could poll the mouse position twice and see if it changes before I realised what he meant. Seeing as the busy cursor is just another cursor you set the mouse to, I am not sure there is a way to tell that this is the cursor being used, but I'm not sure.

I think she's pointing out that the mouse is never busy, it simply shows that the computer is. The rest of the comment was about real mice, living animals, and was obviously meant as a joke. ( Naturally, lauren is free to correct me here ).
I think it may be a little unfair to comment on your grasp of English, but I also think you bring it on yourself, because you seem to ask the same questions over and over, and the net impression is that you're feeding us your projects a bit at a time and not really looking to learn anything yourself. You should check msdn.microsoft.com as a bare minimum before postinmg a question, that site will answer pretty much every question you've asked about the WinNT login sequence, for example.

any LogiTech webcam programmer here? QuickCam SDK?

I dont know anything about the QuickCam SDK, but dont those devices have a TWAIN interface?
|
|
|
|

i downloaded the SDK and started playing with it. The samples are very simple and client implementation almost seems trivial - which is good.
I compiled the project and there's no compile time error and things looked good. The only problem is that it "cant connect to camera" (not using exact phrase here) for some reason. I have re-installed my webcam as well as the SDK and still have the same problem - well, i guess i will have to try do this on a different machine... more, the software that came with the webcam worked as normal. no error no nothing. but the sample project that came with the SDK didnt work for some reason (connection to camera)...
My question is: if u have experience with logitech webcam SDK, it'd be helpful if u can tell me such and such are the usual cause for problem associated with camera connection.
here's the URL:
http://developer.logitech.com/developer/
Thanks.

one cool feature that comes with the logitech quickcam: motion detection =)
it would be cool if u can access the video/individual frames in realtime (image processing)... but perhaps that cant be done with avi.
i think u prolly need to do this by taking a sequence of still shots (jpeg or whatever format it supports) and process each frame individually... anyway, cool toy

Hey guys
I have a CWinThread thread that I start off from a service. I also show a modeless dialog from this thread. My intention is to use SetThreadDesktop and to bring up the dialog box in one of the active virtual desktops. But my problem is that SetThreadDesktop fails and my dialog comes up in the current desktop. If I convert this to a worker thread (using CreateThread) and then bring up my modeless dialog it works fine (I provide the message pump myself).
The document of SetThreadDesktop says this :-
The SetThreadDesktop function will fail if the calling thread has any windows or hooks on its current desktop (unless the hDesktop parameter is a handle to the current desktop).
My guess is that MFC threads do some hooking of their own and this is why SetThreadDesktop is failing. Does anyone know of any work-around to this issue?

Don't know if this is going to help you, but in case you are playing with a service, make sure to check the "interactive user" in the service properties (this can be done programmatically as well).

Hey everyone!
Okay, I need to know how to pass an instance of a class as a parameter for a constructor, and then have that constructor call the constructor of the supplied parameter. Kinda like this piece of code:
class classA
{
public:
classA (int somevalue, classB classBInstance);
void wasteTime ();
private:
classB *classBInstanceCopy;
};
class classB
{
public:
classB () { };
classB (int somevalue);
int something;
};
classB::classB (int somevalue)
{
something = somevalue;
}
classA::classA (int somevalue, classB classBInstance) : classBInstance (somevalue)
{
classBInstanceCopy = &classBInstance;
}
void classA::wasteTime ()
{
printf ("Hey, how about a %d?", classBInstanceCopy->something);
}
void main ()
{
classB myInstance;
classA myClass (myInstance);
myClass.wasteTime ();
}
I think you get the idea: I wanna have a class where the constructor takes another class as a parameter, call the constructor of that class and then later be able to reference that supplied class. How is that possible? I'm sure there's some way using pointers, but how? Oh, and anyone know how I can get rid of that empty classB constructor? As far as I understand it's only there so I can create an instance of classB in the fassion of "classB myInstance". So, if anyone has an idea, let me know!
Thanks

There are several solution. One solution is template.
ClassB<classa> cbObject;
template<typename t="">
class ClassB
{
...
T *Create();
};
template<typename t="">
T* ClassB::Create()
{
T *pT = new T(// Parameter);
return pT;
}

Thanks for the reply! Now I'm not really familiar with templates, so for my special case, where I want the parameter passed to be a descendant of classB (so something declared class classWhatever : public classB), what do I need to do? I can somewhat see the use of templates here, I would probably put a templated class instance into classA and then have classA have called that instances constructor, based on what type of class was passed to classA's constructor. Where do I need to make the changes then?

Okay, this seems to do it just as well:
template <class clType>
class classA
{
public:
classA (int somevalue);
void wasteTime ();
private:
clType classInstance;
};
class classB
{
public:
classB () { };
classB (int somevalue);
int something;
};
classB::classB (int somevalue)
{
something = somevalue;
}
template <class clType> classA<clType>::classA (int somevalue) : classInstance (somevalue)
{
}
template <class clType> void classA<clType>::wasteTime ()
{
printf ("Hey, how about a %d?", classBInstanceCopy.something);
}
void main ()
{
classB myInstance;
classA<classB> myClass (myInstance);
myClass.wasteTime ();
}
Looks good? Alright! Thanks for the hint!

I want to add some documentation to my
program. Something where they can click
Here/Learn More and it just talks about
various topics.
Any one know of a simple demo project
that would do this and that would work
on all operating systems? Please let me
know.
Sincerely,
Danielle (an overworked graduate student)

Sir, If some application running on a PC trying to connect outside word, then how can we know about that. I want to keep watch on all outgoing connections made by all the application. Help me if you can.

Hmm, this seems to be kinda my area to watch. Although my suggestions have nothing to do with coding. There are a few programs online that you can download that will do pretty much what your asking for. I think one such program was called NetWatcher. Perhaps a search on Yahoo, Google, or some other search engine using the keywords, "Net Monitor, Net watcher, IPX logger, Connection watcher" or some similiar keyword might dredge up some good results.

One solution is Winsock. Communicate directly with to server via socket.

What do you mean with how much it cost?
How much memory it takes?
If so, it depends on how much GDI you do...
