BIOSCOM command in c programming

I've been assigned a project in which I've to basically read the information from an interface eg:hardware interface like the device through which employees have to swipe their i.d card when they enter the office...and then through the c program written by us, this data has to be sent to the internet spread sheet of a perticular person eg:in this case the boss... I came to know that this information comes to the computer through the com port. but I wanted to know commands in c which will recieve data from com port.. and also how to access the spreadsheet of the internet thru c commands...

I thought that the 2nd part i.e sending info to spreadsheet can be sent by considering the spreadsheet as a file.... is it possible? If yes how?

I tried few programs that I found in internet, though I have BIOS.h header fil开发者_开发知识库e, it's showing no reference to BIOSCOM command. What do I do? I'm working with borland compiler in windows32.

I just left a job where I was using Borland C++ Builder 5 for 4.5 years. I don't know what version of Borland you are using, but since you mentioned Win32, you can use ReadFile with a DCB Comm structure to read data from the COM port. This website on Serial Communication with Borland C++ Builder will help show you how to do that in a simple example.

As far as writing data to a spreadsheet, well that seems a little rudmentary as far as a database goes, but you can interact with Microsoft Office through a COM interface. You could write a COM DLL using Visual Studio .NET and then make your functions COM visible so older compilers (such as Borland C++ Builder 5) can utilize .NET functions. This would probably be easier than trying to implement a COM interop directly in Borland C++ Builder.
