问题 I create a contact manager. The user can already enter some and they are stored in a file and re-opened when the program is started. Each contact is an object of my Person class. When launching the program (in Load()) I created a for loop until all contacts have been explored (contacts are stored when opened in a Person table) So now I come to my problem: I have a panel that is scrollable (I have enabled the option) and I would like every 50 pixels in height, that a new panel is created with

问题 I am trying to make a query like this dynamic using variables in SQL Server. Original Query (returns results) select * from items where [key] in ('material', 'type') and value in ('nylon/latex', 'general purpose') New Query (returns empty set) declare @keys nvarchar(max) = 'material, type' declare @values nvarchar(max) = 'nylon/latex, general purpose' select * from items where [key] in (@keys) and value in (@values) How can I pass CSV data into these in clauses dynamically? 来源： https:/

问题 Starting with a dynamic array of initially length = 4 and numElements = 0, show the array when we add the followings numbers at the end: 5, 19, 4, 6, -1. The checkpoint (answer) I receive is [5, 19, 4, 6, -1, X, X, X], where X denotes the entries which can be ignored. I have 2 silly questions: I thought insert at the end would make it [X, X, X, 5, 19, 4, 6, -1] instead of what it looks like right now in the answer? I initially though every time we add something in the array, the array would

问题 I am trying to create a tab that displays a list on the left hand fragment and a detailed fragment on the right. When a user clicks a list item, the right hand fragment should change to the appropriate one. I am new to android so I used a tutorial and I know I need to do something with the tablistener: public static class TabListener implements ActionBar.TabListener { private final Activity mActivity; private final String mTag; private final Class mClass; private final Bundle mArgs; private

问题 I have a Drupal website where I post tournament results. I have created a content-type where i write the result for 1 person in the tournament. So the fields are like: Date of tournament, player name, final position. If 10 people played in the tournament, I create this content for each player. Now, I would like to create a table with views, to list all the players in the tournament, and the various info, like player name/final position. I can do that pretty easy by adding the fields and

问题 I wish to expand a structure ( bac ) with a number of fields from another structure ( BT ). The names of these fields are contained in the cell array ( adds ) as strings. this is what i have now (and obviously doesn't do the job, explaining this post): for i=1:numel(adds) eval(genvarname('bac.',adds{i})) = eval(strcat('BT.',adds{i})); end I also tried using sprintf , which did not seem to work for me. I feel confident one of you knows how to do it, since I feel it should be rather easy. 回答1:

问题 How to declare dynamic variable names in Matlab , and the function returns those variables? I want the function that returns the string with dynamic variable name and returns only when number of iterations n is given. I have tried the my following code: function [var] = myFunc(n) for ii=1:n var= ['var' num2str(ii)]; var{ii} = strcat('(some srting', var,')'); eval(['var' num2str(ii) ' = var']); end end 回答1: CASE 1: This will get you the eval strings that you can use later on to actually get

问题 I have a reusable view class, with the function .addDisapearingView() when added to another view displays the text in the functions parameters. Both the label and its container view are programmatically created. When there's long text in the label, I want the label, and the view to both grow in height. When there's text too long for the label, the label doesn't grow-and the text, subsequently, doesn't clip/go to next line. I'm trying to get the container view to expand programmatically based
