If it is application wide, no hooks needed. If system wide, yes hooks needed.

Check the firewall and/or proxy server settings.

a project can be signed as multiple or single threading and more from project-settings.

how does the settimg affect our apps?
in which case, we should use multiple or single threading?

You need to read up on threads a little I think before you decide whether to use single or multiple threads in you application.

See....

http://en.wikipedia.org/wiki/Multithreading

The setting changes which version of the C Runtime library that's linked with your application to either the single or multi-threaded version.

A thread would be needed when you want to multi-task your application. For example when you make an infinite loop(or any blocking function), it blocks your GUI. But if you make it a separate thread, it doesn't. It never disturbs the main thread. And when you specify the multi-threading option (/MD)in your application, it includes the run time libraries that are needed for making your application "multi-threaded".

Okay you've been asking it many times. I think I will guide you to do the same in step by step manner.

1. Create a dialog base application and add an edit box to the dialog.
2. In the menu, click on project->settings.
3. Under "c/c++" tab, you have "preprocessor definitions". There replace <code>_MBCS</code> with <code>_UNICODE</code>.
4. Go to the "Link" tab. There you have project options. Add the following there <code>/entry:"wWinMainCRTStartup"</code>
5. Compile, Build and run.
6. Now you will be able to type in unicode in the edit box of your dialog based app.

Note: If you change the configuration, you will have to repeat steps 2 to 5 for the new configuration too.

After closing my application i am getting a memory exception. I tried to find out with CMemoryState and had put CheckPoints in InitInstance and ExitInstance. I found these lines as last lines in the output window.
What could be the reason?

#File Error#(2094113917) : {-2027659799} First-chance exception in CallLogger.exe (KERNEL32.DLL): 0xC0000005: Access Violation.
First-chance exception in CallLogger.exe: 0xC0000005: Access Violation.
The program 'G:\KIRAN\VC\DEVELOPEMENT\TAPI\Ai-logix\CALLLOGER\CallLogger\CallLogger.exe' has exited with code 0 (0x0).

Thanks in advance.

Most of the time, it's a memory problem at the level of a class destructor.
There are mainly 5 levels of information that you can get about an access violation. See useful information here[^] (look for the Levels of information subtitle.

Possibly, this is because, somewhere you had overwrite memory that doesn't belong to program.
It is difficult point that out without seeing code.

Is your application compiled in debug mode, and are you running it via F5 (as opposed to Ctrl+F5)? This won't solve the problem, but it may provide you with some helpful information.
