• When to call selectRow: on a UIPickerView that has just loaded?

  - by ragnarius

  I am trying to learn iPhone/iOS programming. I have an UIPickerView that should dispay its selected row as soon as it becomes visible (it is contained on a flippSideView). Unfortunately, the flipSideViewController's awakeFromNib is not called. It is too early to call [pickView selectRow ..] from viewWillLoad (the pickView does not exist at that time), and somewhat too late to do it in viewDidAppear. So, how can I make the pickerView display the selected row as soon it becomes visible?

• include link list depending on category

  - by user117701

  I want to display the linklist widget only on a certain category. The current way the sidebar is fetched is: if (!function_exists('dynamic_sidebar') || !dynamic_sidebar(1)) Which doesnt give me a say in the calling of the links widget. If i put an if clause there, then the rest of the widgets dont get loaded. So i either need to customize the links widget it self or find a way to call the links widget directly? And how do i check which category i'm on?

• .NET: How to place my window near the notification area (systray)?

  - by Vilx-

  I'd like to display a little popup window next to the notification area. It's similar to what Outlook/Skype/Live! Messenger/etc does when it displays the notification about a new message. In my case it will have some input controls (textbox, datetimepicker, buttons...) so a simple bubble won't do. The trick is doing this correctly when the user has multiple monitors and/or the taskbar is not located at the bottom of the screen.
