问题 I'm trying to use UI/Slider in Unity app for HoloLens. I used the steps described here - Unity UI on the HoloLens So as a result I have following structure: MainCamera properties: SliderCanvas is using MainCamera : Slider properties: InteractiveMeshCursor is taken from HoloToolkit. As a result I'm getting this picture: When I move the head the Cursor behaves correctly - it stays in the middle of the scene. If I add other 3D objects on the Scene it also correctly changes its states so

What's the difference between using Cursor.Position, SetCursorPos(), SendInput() and mouse_event()?

问题 Cursor.Position, SetCursorPos(), SendInput() and mouse_event() all set the mouse position to a specified coordinate. So what's the difference between them? 回答1: Cursor.Position and SetCursorPos can only be used to change the cursor position. Cursor.Position is Windows Forms; SetCursorPos is Win32. SendInput and mouse_event can be used to change the cursor position as well as generate mouse clicks and mouse wheel events. SendInput is the current API; in addition to generating mouse events, it

问题 Hey. I'm trying to return a cursor object to my activity where its gonna be used in a SimpleCursorAdapter, but Im having a close() was never explicity called error. I cant find any solution for this error, and I'm about to think that its a non-solution error , LOL. Think with me. The error says: close() was never explicitly called on database '/data/data/com.example.myapp/databases/myDB.db' And has a warning too: Releasing statement in a finalizer. Please ensure that you explicitly call close

Set caret position in contenteditable div layer in Chrome/webkit

青春壹個敷衍的年華 提交于 2019-12-07 17:58:33
I'm trying to set the caret position in a contenteditable div layer, and after a bit of searching the web and experimenting I got it to work in firefox using this: function set(element,position){ element.focus(); var range= window.getSelection().getRangeAt(0); range.setStart(element.firstChild,position); range.setEnd(element.firstChild,position); } [...] set(document.getElementById("test"),3); But in Chrome/webkit it selects all of the content in the div. Is this a bug with webkit or am I doing something wrong? Thank you in advance. The offset of a Range boundary within a node is only a

SQL Server cursor - loop through multiple servers and execute query

I have the following code (cursor): DECLARE @SN VARCHAR(20); DECLARE @sql NVARCHAR(MAX); DECLARE C CURSOR LOCAL FAST_FORWARD FOR SELECT DISTINCT(SERVERNAME) FROM INSTALLATION where DATABASETYPE = 'MsSql' AND SERVERNAME IN ('x'); OPEN C; FETCH NEXT FROM C INTO @SN; WHILE (@@FETCH_STATUS = 0) BEGIN PRINT @SN; -- you could loop here for each database, if you'd define what that is SELECT name FROM master.dbo.sysdatabases WHERE name not in ('master','model','msdb','tempdb'); SET @sql = N'SELECT TOP 1 NAME FROM TABLE '; EXEC sp_executesql @sql; FETCH NEXT FROM C INTO @SN; END CLOSE C; DEALLOCATE C;

How to improve performance of a function with cursors in PostgreSQL?

耗尽温柔 提交于 2019-12-07 15:02:13
问题 I have function with two nested cursors. The outer cursor gets payment details of a customer from the source and inserts into the target based on some business logic. The inner cursor takes the payment details of each payment, it happens one after another. The payments table has about 125000 rows, and about 335000 rows for payment details. All of these rows are to be migrated to a target table. Executing the function takes over two hours and the database CPU usage goes up to 99%. I am working

Python, SQLite3: cursor returns duplicates when a commit intervenes

谁说我不能喝 提交于 2019-12-07 13:36:48
问题 This Python code creates a table, inserts three rows into it and iterates through the rows, with intervening commits before the cursor has been fully exhausted. Why does it return five rows instead of three? If the intervening commit is removed, the number of returned rows is three as expected. Or is it expected that a commit (which doesn't even touch the table in question) invalidates a cursor? Edit: Added a forgotten commit (which makes the issue disappear) and an insert to an unrelated

android cursor movetofirst performance issue

血红的双手。 提交于 2019-12-07 13:08:45
问题 i am trying to optimize my application. I noticed that cursor.movetofirst() method somehow slowing the performance of my code. Cursor cursor = myDbHelper.getDayInfo(new SimpleDateFormat("yyyy-MM-dd").format(myCalendar.getTime()); above line executes in 10 ms in 2.1 emulator , and if(cursor != null && cursor.moveToFirst()) this line took about 1.6 seconds . I made little search about this. Somepeople say make it in another thread or in asynctask, but this will make the code more complicated. I

MongoDB: cannot use a cursor to iterate through all the data

独自空忆成欢 提交于 2019-12-07 11:14:00
问题 Update on update: Solved ! See this: MongoDB: cannot iterate through all data with cursor (because data is corrupted) It's caused by corrupted data set. Not MongoDB or the driver. ========================================================================= I'm using the latest Java driver(2.11.3) of MongoDB(2.4.6). I've got a collection with ~250M records and I want to use a cursor to iterate through all of them. However, after 10 minutes or so I got either a false cursor.hasNext(), or an
