I'm using DDE to simulate vi to excel, it display the data to excel correctly, according to what data i entered, but i already assign specific cell to a specific data. i want that for example, the data that has been read is SOG row 1 column 3. and FOG row 2 column 3. how can i distinguished what data read first? bec. if you first entered data FOG it will entered in row 2 and if you entered SOG it will appeared in row 1, if you have a lot of entered data you will not distinguished what data enetered first.
can you please give me an idea how can i solve this?

Thank You

I'm not totally sure if I understand your question, but it seems to me that you have two pieces of data - SOG and FOG. This data will be written to your Excel file in the same location each time. Are you writing FOG and SOG from the same VI? If so, why not use a shift register to keep order? Another option is to insert a time stamp next to the SOG or FOG data and then view the time stamp to know the order. Or, you could write the data to a simple text file. Keep appending the data. When you want to know the order, just open the text file and you will have the insertion sequence there. Good luck.
