How about GetSystemMetrics(), or GetDeviceCaps()?

If you want to take account of the taskbar, use SystemParametersInfo with SPI_GETWORKAREA. Bear in mind that on a multi-monitor system, each monitor can have a different resolution.

I have been putting it off for a month now because i couldnt find a real good place to start studying for this. So i figured I would ask you all here if you recommend some nice places or books to read to work with Internet programming using Windows Sockets or (if you think it is better) any other socket programming.
obviously if at all possible I'd like to study Windows sockets 2, but 1.1 is ok I guess. Remember before you say go read MSDN I am really new to Internet/Network Programming, so something that will guide me is truly the most helpful.
Thanks

What does being new have to do with (not) reading MSDN? In addition to that, I would suggest Googling for specific topics, and perusing this section of CP.

Learn winsock programming via books. I highly recommend Network Programming for Microsoft Windows Second Edition by Anthony Jones and Jim Ohmund.
Check out my website for software development links.

Thanks Waldermort for your contribution. I wish to capture keys from the keyboard using system-wide windows hooks. I'm not using MFC but Visual Studio's WIN32 Application and DLL. I don't know how to capture keys such as * . + @ # % & etc. How can I do this?
I'm using the following:
if (((keyvalue>=0x41) && (keyvalue<=0x5A)) || (key==VK_SPACE))
to capture keys a..z and the spc key.
Thanks

you would have to trap and test the value of your WM_CHAR message. You would normally do this in your message loop and send the chars to your winproc.

Sorry, but how would I do this?

I am working on some project and can't overcome some errors. I can't understand how typecast is done in C++/C. What if we convert smaller type to bigger - how is it done? And bigger to smaller? Do we just truncate the data to biggest one or... what?
I would be grateful if you could explain that to me.

No problem. In fact, some types are automatically promoted.

There is potential loss of data.

Thanks, but I ment what there would be if we convert, for example, int to char - truncated or maximum number? And what about other convertion cases?

There would be loss of data if the int value was 128 or greater.

I think he is asking, if you cast an int down to a char, does the char take on the value of the least significant byte of the original int, or does the char take on the value of the highest value that a char can hold.
For instance, if the int held the value 50, then it's clear that the char would take on the value 50, but if the int held the value 356, would the char take on the value 128 since 128 is the highest number a char can hold?

No, it would "wrap" all the way back around to (positive) 100. The leftmost 16 bits would go away. A better example would be if the int value was something like 200. The resulting char value would be -56. The leftmost 16 bits still go away, but now the sign bit is 1, indicating a negative.

B='a';
hPort =CreateFile(pFileName,GENERIC_READ| GENERIC_WRITE,0,NULL,OPEN_EXISTING,0,NULL);
rc=WriteFile (hPort,&B,1,&dwNumBytesWritten,NULL);
CloseHandle (hPort);

I'm looking for a quick template or sample code to write a quick "installer" type program in (not managed) C++ to install items to the PROGRAMS folder that simply are links to a website.
For example, START / ALL PROGRAMS / MY FOLDER / Link 1, Link 2, etc.
Does anyone have anything like this?
