Why can't i open uigetdir dialog box while run the program?

6 views (last 30 days)
When i place a break point on the line of function uigetdir(), i can open the dialog box when i step over (F10) the function line.
But if i remove the break point and run the program, the execution will pass the line of function uigetdir() and no dialog box shows up.
I wonder if i need to add uiwait() after that, but i don't know how to use it. If i directly add uiwait() after it, it will hold the whole program.
Thanks!

You don't need uiwait() after the call to uigetdir(). Can you post a small snippet of the program to illustrate your problem. For example, this code definitely asks for the folder before it puts up the message box:
clc; % Clear the command window.
close all; % Close all figures (except those of imtool.)
clear; % Erase all existing variables.
workspace; % Make sure the workspace panel is showing.
folder = uigetdir();
msgbox('Done with demo');

so anyway i can let uigetdir() hang a little bit longer? Actually the hanging time is not that long... Thanks!

I'm sure it doesn't take that long for you because you have access to that folder on your server. But the point is, I don't see any difference depending on if there is or is not a breakpoint. Either way it calls uigetdir() before it continues on.
