guys, thanks a lot, but, why do i have to enter the file name before I start the program? I don't want just a header in the first 3 columns (Name, ID, Place) it should be
just the same like the updating of the wfm column... something like this...
Your example file does not match the data that you're collecting. Your DAQ Assistant is set up to read 10 samples. Is this supposed to be 10 rows in 1 column, or 1 row with 10 columns of values? Also, the controls on the front panel make no sense as far as column headers are concerned. When you connect this to the Format Into String function you will not get an array of values - you'll get just one value. If you want all 10 values then you need to do as suggested and use the Convert From Dynamic Data VI to get the appropriate datatype.
@ smercurio_fc I could not get your VI running, you have some custom VI in it/?/ write to spreadsheet.vi? I don't have it in my LV 8.0
In LabVIEW 8.0 the Write to Spreadsheet File exists - it's in the File I/O palette. The VI would have been found - it would just have a broken wire for the instance that's outside the loop. The issue is that in that version the VI is not polymorphic. Only a version that accepts floating point values exists. In LabVIEW 8.2 and beyond it's polymorphic so that you get a floating point version, a string version, and an integer version. If you open the VI it gives you instructions on how to create a version that accepts strings. The change is trivial, but you must save the string version in your own directory, NOT the LabVIEW vi.lib directory.
Alternatively, you could just use the Write to Measurement File VI since you are dealing with that clumsy DAQ Assistant, which creates that horrible dynamic data.
