The first image is the "privacy" panel, it has the option to remember the setting. It is specifically invoked (as shown in the link in @lazfish's comment) by calling Security.showSettings(SecurityPanel.PRIVACY); . The second dialog is a default dialog shown by Flash player when an app tries to use the camera

When I quit and restart Xcode, all folders in the Project Navigator are shown expanded, so I have to collapse most of them manually. Is it possible to save the state of the Project Navigator , so that when Xcode restarts the same folders are collapsed / expanded as before? 回答1: The solution was to delete this file: MyProjectName . xcodeproj > project . xcworkspace > xcuserdata > myusername . xcuserdatad > UserInterfaceState . xcuserstate This file was recreated by XCode when re

For example: http://example.org/users/index/moderators/page:2/sort:name/dir:asc here moderators is a parameter that helps me filter by that type. But pressing a paginator link will not include this link. 回答1: To add to Alexander Morland's answer above, it's worth remembering that the syntax has changed in CakePHP 1.3 and is now: $this->Paginator->options(array('url' => $this->passedArgs)); This is described further in the

That means the array remembers what type it must accept. But the List

Then, using the mouse, I rotate it some way. Now I run the command again, expecting to obtain the original shape (i.e the original orientation before I rotated it by mouse), but instead, it just gives me the same plot I have on the screen, i.e. it seems to have kept/remembered the last viewpoint in that output cell. I wanted it to go back to the original viewpoint. So, I delete the output cell to make it happen. Do you think this is how

Is there a way to have the form remember which files the user has already selected if they hit submit but need to go back because one of the text fields didn't validate? 回答1: You can't "pre-fill" the contents of a file upload field for security reasons. Also, that would mean the file would get re-uploaded every time the form is submitted, which would not be good. Instead, do this: Create a file upload field with name file_upload .
