Path control's browse cancel buton return value

[Rashid-Malik]

How can I find out which button (especially cancel button) user had pressed?

 

 

Thanks for helping!

Have a very pleasant day!

As far as I know there isn't a way, other than seeing if the filepath has changed value. One workaround is to not display the browse button, and use your own button which calls the Windows API functions or the .NET file dialog functions which will tell you if the dialog was cancelled.

The LabVIEW "file dialog" function in the advanced pallette also provides this information, but you'll have to create your own button to accomplish this.

Maybe a product suggestion to expose this information in the event structure is in order.

Oh yeah.... that Express (Saverio says this with indignation spewing from his lips) VI.

Thanks smercurio… for the insight!

Thanks a lot andre.buu…! I think this is the suggestion I'll be working with.

If you're using the "value change" event on the path control, the event will fire only if the user clicks the OK button (or double-clicks a file). It fires even if the path does not change if the user clicks OK.

The event does NOT fire if the user clicks Cancel.

Dear smercurio…! I think I don't understand the implications behind your comment. Would you kindly let me in on this "that Express" thing? (Looks like some inside laugh!).

He's a member of the club "I don't like express VIs". So am I

I don't like Express VI's too, but there are some that are usefull, e.g. "File dialog" and "Time delay" (after displaying them as subVI and unchecking display caption).
