File Open Dialog / multiselect / GetOpenFileName API Call

[Andreas Schmack]

Hi!

Is there a possibility to select and open more then one file in some of the
standard file dialogs under LabView at the same time?
A lot of windows programs are supporting multi file selection in their file
open dialog.
I tried to call the GetOpenFileNameW function of the comdlg32.dll but I've
got some problems with the datatype it needs. Non zero-length strings result
to a lot of strange characters in the dialog.

Maybe I'm oversimplifying your question but I downloaded a VI from NI which
acts like an open file dialog in "Windows" and allows you to multi-select.

Go to the Developer Zone and search for "multiple file selection dialog box"

Thank you - I found it. Don't know why I did not find it yesterday.
Unfortunatelly it does not do what I really want (but maybe I can modify it
by myselve).
The problem is, that I would like to select about 1000 files and the VI does
not support
a multiselection mode using the shift-key like under windows (or did I
overlook something?).
Clicking to every single file is a bit too much 😉

Hi,

It can be done, the trick is, indeed, to 'decode' the return message. The
returned message is an 'array' of strings, inLV a string, with elements
seperated with 'NULL', the string ends with 'NULL','NULL', if recall
correcttly.

Another thing is the API you call; GetOpenFileNameW will return names in UNI
code, use GetOPenFileNameA will return names in ASCII, wich is a lot easier
to work with in LV.

Regard,

Wiebe Walstra.
