Error 1 is to open file vi:. Openfile occurred - Fehler 1 ist bei Open File .vi:Open File aufgetreten

Question

Hi there,
I'm using Labview 7.1 and Windows 7.
I built a VI and it ran perfectly yesterday. Today when I tried to run it, the following message appeared:
Fehler 1 ist bei Open File+.vipen File aufgetreten
Mögliche Gründe:
LabVIEW:  Ein Ausgabeparameter ist ungültig.
NI-488:  Befehl erfordert, daß der GPIB-Regler der aktive Regler ist.
Translation (google translator):
Error 1 is to open file vi:. Openfile occurred
Possible reasons for this:
LabVIEW: An input parameter is invalid.
NI 488: command requires that the GPIB controller is the active controller.
In the attachment I am sending the file. The file is very simple. I'm just importing some data from excel.
Regards
Solved!

I have the VI in a loop, because I want to make operations with a specific cell from Excel in each iteration. First loop, use the first cell, second loop the second one and so on. Maybe there is another way to do that, but that is how I figured it ou. If you have any suggestions to make it simpler I appreciate.
First of all, you don't have an "excel" file, which is a proprietary format. You have a delimited plain text table with semicolons separating columns and linefeeds separating rows.
You have only one loop. You are probably talking about first iteration, second iteration etc.
Your loop spins so fast that you will only see the last row after the VI has completed. Use a small wait.
All you need is the following code (looks slightly different, because it is LabVIEW 2010). This will display all rows in sequence for however many rows you have. If you only want to display the first 5 rows, you can wire a 5 constant to the N of the FOR loop.
LabVIEW Champion . Do more with less code and in less time .
