问题 I have a user control that contains a textbox and a combobox. I have exposed the combobox's Item property to clients of the user control, thus: public System.Windows.Forms.ComboBox.ObjectCollection Item { get { return baseComboBox.Items; } } I added the user control to a windows form, and set the Items list using the property values editor in the form designer. I then ran the application, and the combobox's drop down list was empty. To confirm that the items added at design time were not in

由 核能气质少年 提交于 2019-12-11 02:20:09
问题 I am writing a program in which a user inputs values into a list until the want to end it and the program will tell the user the longest streak of numbers they entered.

So far I have this and it seems to not want to ever end the current run so if i enter 7,7,7,6,6,6,6,5,4 it will tell me the longest streak is 7 like it is continuing the streak from the 7

Android: Listview duplicates itself when I launch a new activity and press back to go back to it

由 匆匆过客 提交于 2019-12-10 13:16:50
问题 I have two list views that are fragments in view pager tabs. When you click on the items in the list view it launches a new activity. But when I press the back-button to get back to the tabbed list view, the list view has doubled and if I open the activity and go back again it doubles again and it will keep doing that. Also I have another tabbed list view with five tabs and when I go two tabs away from one of the views. The items in that view double when I come back to them and this is the

Is there a ComboBox that has Items like a TcxRadioGroup?

由 末鹿安然 提交于 2019-12-10 11:54:45
问题 The TcxRadioGroup component of DevExpress has a very nice way to specify items. You can specify a Caption and a Value (and a Tag) for each TcxRadioGroupItem. The TcxComboBox and the normal TComboBox of Delphi on the other hand use TStrings to store its items. While TStrings can have a Name and an Object, there is no easy way to hook up a name and a value using the form designer of the Delphi IDE. Is there a ComboBox control (preferably from DevExpress) that allows to visually design its items

HowTo: ListView, Adapter

由 我与影子孤独终老i 提交于 2019-12-09 10:38:55
I was surprised that getViewTypeCount() is so rarely overrided. If you are an expert in this – this post is not for you) ListView and Adapter Basics How it works: 1、ListView asks adapter “give me a view” (getView) for each item of the list 2、A new View is returned and displayed Next question – what if we have one billion items? Create new view for each item? The answer is NO,Android caches views for you. There’s a component in Android called “Recycler”. 1、If you have 1 billion items – there are only visible items in the memory + view in recycler. 2、ListView asks for a view type1 first time

问题 I am building a simple app in xcode 3, but don't know how to code the appmenu items. I have a few simple items that need codes - open and print. Close and minimise are done automatically.
