Do you really think that changing the suffix to jpg is actually changing the file type? There is a good reason that bmp files are not allowed.

p.s. The error message is pointing to 2 possible reasons - note the plural! Look into the first possible reason since you do not have GPIB.

Your code indicates that you've copied and pasted without understanding what the example program was doing. For example, the way you've done the comparison of the two dates and the greater than function is just silly.

I've made some changes and cleaned up some of the problems in your DAQ code. Give it a try. I would suggest testing the new file creation ability by changing the windows date/time instead of waiting 24 hours.

hi i checked ur modify vi its working

thanks ...........very much

but in that (entry,date,time,speed) that constant should be as hedar of file

only onces it's should to come at the beging of file but its also repeted when data has comes.

will you please tell me how to place constant hedar .

well happy new year to all of you

You would simply write the header in the case where the file is created.
