point to a file on my C:\\

[kmous]

Hi I have a structure inside a loop contains true , false ,temp and open .....when i choose from my menu Open , i have to open a file on my c:\\ drive ...how do i do that ? what should i insert inside my structure ?

thank you 🙂

You'll need to provide a better explanation of what you're doing. What is this "true , false ,temp and open"? When you say "when i choose from my menu Open" are you referring to a custom run-time menu? Are you trying to open a file directly, or provide a file selection dialog? What File I/O functions are you using?

The best bet: show us the code.

Is this a case structure with four cases?

What do you mean by "open"? What kind of file? What do you want to do with the open file?

If you are on windows, "C:\\" is not correct syntax, try "c:\". Do you want a file dialog or do you know the filename already?

Maybe it would be easiest to attach your program so we can see what you actually have.

This is my file

Use System Exec (Connectivity -> Libraries & Executables). Set the "wait until completion" to True or False accordingly...



With respect to your code:

• Why do you set the pane color each time you loop? Isn't once enough? Why don't you just set it directly on the front panel, rather than programmatically?
• Are you sure you really want to use "Quit LabVIEW"? Is this intended to be built into an application?
• I would suggest using the Event Structure rather than a while loop.

Hi kmous,
click Shift and right mouse key at the same time and select the brush. With another right click on the front panel you can change the color.

Hope it helps.
