RE: Win32 - System Admin Discussion Boards

Thank you
I will try that
I also saw some mentioning about a possibility that the network card also may cause these problems
I will try your suggestion and will post the progress.

pardon my ignorance.. What are Reference Drivers.

Thanks in advance

I want to read and write the TCP/IP Seetings of WinNT with an C++ or Delphi Programm. Does someone know, where I can find these seetings in the Registry, or so?

For NT
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip
should be somthing similar for Win9x

Win32 is a 32 bit operating system. I wanna ask why are the # of bits of OS important for a programmer. Whats exactly the difference between a 32 bit OS and 16 bit OS.

I am sorry about the previous post, this is my first time and I was confused.

Many people will give you long lectures about differences and there will be many variations of the answer but I think there is no clear definition. People say that 32-bit operating systems have this and that and some people say that the processor has this and that but there are usually many inconsistencies in those answers. I think that classifying operating systems and processors is just not as easy as many people would like it to be.

The difference is the size of the optimal integral type. In C/C++ this would indicate (usually, any way, though there's no guarantee) the size of the int type.

There are some other differences that are really kind of specific to the Intel architecture. A 32 bit OS on an Intel platform can use a "flat addressing" scheme, where as a 16 bit OS uses a "segmented architecture". This means the 16 bit OS can address memory only in 64K chunks, while a 32 bit OS can address memory directly (limited to 4,294,967,295 bytes).

This corresponding to the size of a pointer. In Win64 there will be 64 bit pointers, in Win32 there were 32 bit pointers, and in DOS we had 16 bit ones. However far pointers could be used to access memory outside the 64k region of a particular segment. So I think the bit correspond to the addressing capabilities of programs.
