interactive file path

[isaac.fr]

Hi,

I am developing a VI that need open an ASCII file. The whole VI is contained in a While loop, except the file path VI (otherwise, the user is continuously asked which file he wants to open ...), but I would like to be able to change the ASCII file I want to read while running. How can it be done?

Thanks a million.

Use STATE MACHINE. And you can have different states corresponding to:

1. Selecting a File

2. Reding File

3. Updating GUI

4. Blah Blah

5. Blah Blah

.

.

.

and last Exit state.

As soon as file will change inside while loop you can perform the read operation

Hello Isaac,

I don't know if you have access to Self Paced Online Training, but this also might prove useful:

If you don't have an Active SSP, then the following pages will also prove to be useful:
