Hello,
I am VC++/MFC developer. I wanted to start Bluetooth socket programming. Can you suggest any good book or article specific to Bluetooth programming.
Regards

Actually I went through all these pages..but I am not getting what I exactly want. I have completed my application using these pages, I myself not willing to use that.
I know I need to use Winsock2. But still something is not working properly.
Regards

Get a copy of the latest Windows SDK[^] and take a look at the bluetooth example in C:\Program Files\Microsoft SDKs\Windows\v7.0\Samples\netds\winsock\bluetooth

OK. I will try and let you know. Thanks

You could check out the source of my Bluetooth remote control written in C++/MFC. It uses modified MFC CAsyncSocket to listen to Bluetooth connections.

There are couple of things i can think off.
1. put sites url to a ini file for example then use API for working with inifiles (write / read profilestring)
2. get a list from ini file and resolve each site's ip
3. put then these ips into C:\Windows\System32\drivers\etc\hosts file and redirect to localhost for example
4. write a driver to disable write permissions on that file (you need to hook ntwritefile and some more)
5. that still will not block apps, which use custom resolver (anyways, most of apps use gethostbyname).
Or, maybe, detect network threads, then inject own thread into them and block access to a site on that level.

Hi,
I have added following line @ hosts file
66.220.146.11 www.facebook.com
but still facebook is running.

It should be:
127.0.0.1 www.facebook.com

The simple solution is having a program that modifies the hosts file, and gives the blocked domains an invalid IP address.
The normal solution in a corporate network is to setup a filter on the gateway to the Internet.

Can you please give me steps how should I filter gateway?
|

The gateway is a seperate computer working as router, that includes its own software for configuring DNS lookups and firewall.
Usually the router provides a web-browser interface that allows one to configure it. Not something you would do through a MFC application.

I am trying to access shared memory on an ISA bus card, under Windows XP. Is there any simple way to do this in C? I would be working in VS6 since I have it installed on a spare machine, I have not done any real software work for years.
I had a similar problem years ago, where I wanted to access I/O ports on an ISA bus card, and found InpOut32.dll which provides direct port access under Windows XP. Wonderful stuff. But is there anything similar that allows physical memory access?
From what I remember, there should be no problem if I run under Windows 95 or 98, right? Just set a pointer to the address I want and read or write freely, or does Win95 / Win98 protect some memory areas?
I'd hate to have to dig up MSVC 1.52C, to compile the program for DOS!

I try to make an CComboBoxExt derived from CCOmboBox . In
void CComboBoxExt::OnEditchange()
{
CString sText;
GetDlgItemText(this?,sText);
ShowDropDown();
}
I try to retrive the text that user entered in combobox , and if text is not empty show drop down list , if is empty then hide drop down list .. but I stuck on GetDlgItemText method : how can I retrieve the text that user entered ? Can you help me please ? Thank you !

To retrieve text from the edit box of the CComboBox, use GetWindowText(). To retrieve text from the listbox, use GetLBText().

I have Visual Studio 2008 at work but I must admit I've only used it for C# applications so far. I ported a reasonably large MFC app (from Visual C++ 2003) to it a few months back as a proof of concept and realized some important features of ATL were removed for webservices and regular expressions. I hacked around to get it to compile and the experience was somewhat painless (except for the regular expressions omissions off course).
However, I've not really toyed with in C++ beyond that and I'm looking to purchase a personal copy of Visual Studio 2008 (or 2010 but the reviews for 2010 seem pretty bad and I like to stay a step behind the leading edge for IDE's) and I wanted to ask those of you who have beat Visual C++ 2008 up a bit to see if you feel like Visual Studio 2008 was a good investment.
Specifically looking for opinions from those who still prefer to utilize MFC/ATL shared libraries for collection classes, CString, etc... as opposed to the C++ standard library equivalents.
thanks in advance.

I have ported many apps from VS6 to VS2008 for my clients. No major gotchas, and using VS2008 for x64 development presents no problems either.
VS2010 is an entirely different story. Extremely slow startup times, several crashes during the day, and, of course, a help system that is near totally useless (I use google instead). VS2010 is not worth it, unless there are features you really need.
To be honest, I have found that MS has fixed numerous bugs in the MFC Feature Pack stuff in VS2010. But most of my clients hate the ribbon interface, so I'm not sure if that is a major benefit.

I agree about the ribbon interface since the 16:9 aspect ratios of contemporary monitors tend to make vertical screen real estate ever more precious.
Thanks for taking the time to share your thoughts. It is much appreciated.

I would probably wait for VS2010 Service Pack 1 to arrive, and see if it fixes the things for VS2010. I think over time you will be developing more .NET applications, and the improved WPF designer and .NET 4.0 will be good to have.
VS2008 without Service Pack also had a lot of bugs.

I agree, SP1 will help VS2010 a lot. I've been using the SP1 Beta with no problems and it's help viewer is waaaay better.
If you use STL, VS2010 is much nicer with the elements of C++0x they've included so that's definitely better than VS2008.
I've not experienced the slow startup times others mention so I think some of that's tied to your h/w such as RAM.

I've used VS2008 for C++ with MFC extensively and really like it. Probably one of the best C++ IDEs to work with. It does have SP1 out so watch for that specially if you're using it within Win Vista or 7 (there are frequent compilation errors that get fixed with SP1). I've used Studio 6, 2003, 2005, and 2008. This is the best one yet. With that said, haven't used VS2010.

I'm using XP Professional at home and at work but I'm guessing we can't hold out much longer. I've only tested our compiled products (before releasing to production) on Vista and Windows 7 and had not had a chance to test any versions of Visual Studio on either OS yet so your comments are helpful and encouraging.
I did some searching before I posted and have been watching any comments made on 2008 and 2010 over time but I couldn't quite get a good handle on the C++ experience as so many are using C# to pay the bills these days.
Thanks for taking time out to share your thoughts.
