Hi,

I couldn't load it in my 5.0 version, the error says 'version of VI is
newer than labVIEW version'

Thanks for converting it, I think I will be ok going from the screen
capture...

Thanks for your help!

Hi LV Newbie,
 The answer that the other user posted on the forum is
 what you need. I have access to a copy of Labview 5.0 and I'll try to
 convert his code to 5.0 for you.

Hi, thanks so much - that sounds like it might be the answer. Umm, my
LV version is 5.0 (I know, I know - not my choice!). Is it possible
for you to save the file in 5.0 for me?

Thanks so much

Re: DDE in loop

Thanks for your answer - but I'm not sure if thats what I need
exactly...

Ok, so I have 9 LEDs inside a For Loop (N=0-8). When N=0, it does its
stuff with LED1, and sends the data to Excel...then N=1, etc etc.

Thats all fine, but the problem occurs after I've been through my
first 0-8 loop...and going to repeat the whole thing again. So I don't
see how the Case structure would work. I need a way of the first time
N=0, for the data to go to column 1, row 1-4, but then the second time
N=0, I want the data to be sent to column1, row 6-9... and so on for
N=0-8 several times.

Do you see what I mean? Sorry if I'm not explaining this well

DDE in loop

[LV_newbie]

Hi.
I have a program with 9 LEDs in a For Loop. After each LED is tested,
it sends the data to Excel through DDE. It is working fine for the
first time through the whole For Loop, but when it goes through the
loop again (0-8 afor the second time), my original data in Excel gets
replaced by this new data. It is because I specify what columns to
insert the data into. Is there any way of updating my string input (on
where to place the data) so that it changes with each for loop?

Hi:

Inside your for loop, place a case structure and wire the iteration
terminal to the question mark of your case structure.  The case
structure should now have 0 or 1 case.  You can add more cases by
right mouse clicking on the case structure and select the add case
option.  Now within each case number, place a string denoting what
Excel cell to update with each interation.

Have fun
