问题 Problem Solved: For anyone in the future who has this problem, I found this this nice tutorial: http://www.androidbegin.com/tutorial/android-delete-multiple-selected-items-listview-tutorial/ and re-adapted it to my own use. I didn't use the MultiChoiceModeListener with the ActionBar, I used my original OnClickListener. Also I couldn't get their highlighting from the xml to work so I kept my original highlighting code. There was a problem with the color not disappearing after I removed the

问题 This question already has answers here : Add new keys to a dictionary? (15 answers) Closed 6 years ago . I want to add an item to an existing dictionary in python.

问题 I couldn't find a proper event which fires when my ComboBox.Items count changed. Is there any way to do so? 回答1: Bind ComboBox ItemsSource to ObservableCollection, then you can catch the event CollectionChanged of ObservableCollection EDIT: In wpf it is recommended to use binding instead of accessing UI element properties directly, of course better to use MVVM, but you can live without it too in your Windows or UserControls C# code you can keep property like this public ObservableCollection

问题 I have a macro that works for forwarding multiple Outlook items as attachments. I've pasted that below, but I want it to also add the forwarded message(s) to a category in outlook.

问题 I need to move a heavy quantity of items between two collections. I tried to change direct at database the tables "item" and "collection2item", columns "owning_collection" and "item_id" respectively. Then I restarted tomcat, cleaned the cocoon cache, rebuilt the index and it's still not working. Is the process metadata-export/metadata-import safer or easier than the above for mass move of items? What else can I do? 回答1: Your process should be ok if you run the reindex with the -bf flags (just

问题 first I must apologize because english isn't my mother language, but I'll try to be clear in what I'm asking. I have a set of rows in a tableview, every row has diferent comboboxs per columns. So, the interaction between combobox must be per row. If in the Combobox A1, I select Item 1, in the Combobox A2 the itemlist will be updated. My problem is that every combobox A2, B2, C2, etc. Is being updated according the choice in A1... same thing with B1,C1 combobox. I need to updated just the A2,
