Via Serial port(rs232)
So just search CP articles for "serial." http://www.codeproject.com/system/serial.asp[^] http://www.codeproject.com/system/chaiyasit_t.asp[^] http://www.codeproject.com/internet/serialporttocommunicate.asp[^] http://www.codeproject.com/system/simpleserialcomm.asp[^] http://www.codeproject.com/system/cserialcom.asp[^] You can also Google for the same.

How to record/process data sent from the sensor????

Having not coded very much serial stuff before, this is just a guess. Those other articles I referenced would have shown this, but I think you'll use something like:
HANDLE hPort = CreateFile("\\\\.\\COM1", ..., OPEN_EXISTING, ...);
ReadFile(hPort, ...);Also see here.

am using Send() and Recieve() functions lnewlength = send(lnewSocket,(char*)lnewData,lDataLenght,0); lnewlength= recv(lnewSocket,(char*)lData,1024,0);

Can those be used with serial communications, or are they for sockets only?

they are for sockets....
Then why are you using them with a serial port?

Actually, if i would like to store the data of the "lData" parameter when lnewData[]={.....}(soem bytes) in storearray[], the how could i do? Is this correct?? if(lnewdata[8]==({..,..,..,..,..}) { BYTE storearray[1024]= lData; } can i work so with a string???

I doubt it.

What is
lnewdata? Are you comparing or (supposed to be) assigning?chaitanya22 wrote:
BYTE storearray[1024]= lData;
What is
lData?

What is this? Try:
BYTE compare[8] = {0x02, 0x00, 0x02, 0x00, 0x20, 0x24, 0x34,0x08};
if (memcmp(lnewData, compare, 8 * sizeof(BYTE)) == 0)
{
memcpy(storearray, lnewData, 8 * sizeof(BYTE));
}
