A USB temperature logger will be used in this demonstration, but any data source can be used. Information on the USB temperature logger is available here:http://www.instructables.com/id/EV9KA88GBMEQZJJOR5/
SyndicitGATE is a very simple (Windows) Visual Basic program with 2 functions. It includes the functionality of the sample program included with the USB temperature logger: it uses MSCOM32.OCX to send a request for data through the USB port. The response (a temperature measurement in this case) is put into a HTTP POST request and sent to syndicit.com using mswinsock.OCX. (You will need both of these common Windows files for syndicitGATE to work. You should already have them, if not, consult Google.) Source and compiled executable are included in the project archive.
***Note: trialexsays: You mention you need the file "MSCOM32.OCX" - I think this should read "MSCOMM32.OCX". I also needed to go and find the file "COMDLG32.OCX"*****
