• Understanding Twitter API's "Cursor" parameter

  - by Adam

  I don't really get how to use the Curesor parameter in Twitter's API, for an exmaple - here. Am I supposed to make a new API call for each 100 followers? I'd love it if someone could provide a PHP example for getting a full list of followers assuming I have more than 100... Thanks in advance!

• C# - Pan cursor

  - by Ash

  I'm implementing panning of a large image in a PictureBox control, and I have no problem setting the appropriate directional pan cursors. However, I can't seem to find the image used for the origin of the pan (a circle with arrows inside of it). Where can I find it?

• ADO "Unspecified Error" instead of actual error when fetching server side cursor

  - by Dan

  This relates to my recent question: http://stackoverflow.com/questions/2835663/force-oracle-error-on-fetch I am now able to reproduce a scenario where using ADO with the Oracle OLEDB Provider, I can force an error such as ORA-01722: invalid number to occur on calling Recordset.MoveNext However, this is not the error that is returned to the application. Instead, the application sees Provider error '80004005' Unspecified error. How can I get the application to see the real error from the database? This is with Oracle 10g (client and server), if it matters. Sample code is roughly as follows: Dim con As New ADODB.Connection Dim cmd As New ADODB.Command Dim rs As ADODB.Recordset con.ConnectionString = "Provider=OraOLEDB.ORACLE;Data Source=xxx;User Id=yyy;Password=zzz" con.CursorLocation = adUseServer con.Open Set cmd.ActiveConnection = con cmd.CommandText = "select * from table(ret_err)" cmd.Prepared = True Set rs = cmd.Execute While Not rs.EOF rs.MoveNext Wend

• Android Cursor strange behaviour

  - by sandis

  After many houres of bug searching in a big app, I have finally tracked down the bug. This logging captures the problem: Log.d(TAG,"buildList, DBresult.getInt(1): "+DBresult.getInt(1)); Log.d(TAG,"buildList, DBresult.getString(1): "+DBresult.getString(1)); Log.d(TAG,"buildList, DBresult.getInt(4): "+DBresult.getInt(4)); Log.d(TAG,"buildList, DBresult.getString(4): "+DBresult.getString(4)); The resulting output: 05-06 11:11:20.123: DEBUG/TodoList(18943): buildList, DBresult.getInt(1): 0 05-06 11:11:20.123: DEBUG/TodoList(18943): buildList, DBresult.getString(1): false 05-06 11:11:20.123: DEBUG/TodoList(18943): buildList, DBresult.getInt(4): 0 05-06 11:11:20.123: DEBUG/TodoList(18943): buildList, DBresult.getString(4): true There are no backgroung threads running. As you can see the problem is that '0' is interpreted as false on one occasion, and as true on another. Since I am completely lost on how this can happen, I dont know how to proceed. What could possibly result in such a behaviour? Both the columns are of the type "boolean", i.e a numeric in sqlite. Unfortunately the string returned is the correct value, while the integer is always 0. If I export the database to my computer and check it with SQlite Administrator I can see that the values are correctly set, it is only the getInt()-function that always returns 0. I know for a fact that this works in other apps I have coded, and I dont know why this has stopped working. I have tried compiling the code under 2.0, 2.0.1 and 2.1, and it always appears. I can make my app runnable again by getting boolean values like this: myBool= (DBresult.getString(0).equals("true")); but that is both ugly and not optimized. Any suggestions on what is causing this behaviour is welcome. Cheers,

• SQL question - Cursor or not?

  - by grady

  Hi, I have a query which returns 2+ rows. In those results is a column which we can call columnX for now. Lets look at those example results: columnX 100 86 85 70 null null I get 6 rows for example, some of them are null, some of them are not null. Now I want to go through those results and stop as soon as I find a row which is < null. How can I do that? Thanks in advance :-)

• Android: Sorting a merged cursor

  - by tonyc

  Hi, I'm wondering if there's any way to merge two cursors together and then resort them. I can easily merge two cursors together by using a MergedCursor, but that doesn't sort them. I have two sets of contacts in two separate cursors (with totally different schemas) and I want to merge them and sort them by name (the name column is different in the two cursors). Is this possible? Thanks, Tony

• Remapping keyboard to get extra cursor keys - but why stick to VIM standard hjkl

  - by Carlo V. Dango

  Inspired from VIM I recently remapped my keyboard layout to get extra keys for cursor movement. Being fluent in both QWERTY and DVORAK, it came quite natural to me to remap the DF and JK keys rather than the VIM standard hjkl keys. Here is my reasoning It enables me to quickly identify cursor keys since F and J are physically marked on my keyboard I'm using two hands for movement rather than one. I guess from DVORAK I learned to appreciate shifting between hands rather than using primarily one hand. It maps well with the Kinesis keyboard mapping http://www.kinesis-ergo.com/advantage.htm that I use occasionally. I feel I'm using my strongest fingers. I don't have to stretch my right index finger to read H as I would using the VIM layout. However, since I am still doing green field explorations on the cursor key remapping, I'd like others to share their experiences and/or criticize my suggested mapping. PS. If you want to toy around with my remapping using Autohotkey here is my script ; extra cursor keys. !d:: Send {Left} <^>!d:: Send {Left} !f:: Send {Right} <^>!f:: Send {Right} !j:: Send {Up} <^>!j:: Send {Up} !k:: Send {Down} <^>!k:: Send {Down} The question Is this mapping sane or is the VIM mapping superior?

• Can't disable giant cursors (from accessibility mode)

  - by jackweirdy

  I've just installed ubuntu 12.04 from a livecd. Out of curiosity, I enabled the accessibility options for people who are hard of sight. As you can guess this does the usual stuff of inverting colours, increasing text size and making the cursor larger. Having finished the installation I booted into the new system to find accessibility mode was still installed. From the lightdm login screen I disabled this which switched colours and text size back to default, however it's only the pointer cursor that has gone back to default. To put it another way, the "hand" icon that you get when hovering over a link, the cursor which appears when typing and pretty much every other cursor on the system are still large. I've looked on the Universal Access menu, but there's no option to disable large cursors. I've tried toggling accessibility on and off but to no avail.

• External monitor with NO mouse cursor

  - by Csaba Nyerges

  I am using a Fujitsu Siemens Amilo L7310 laptop computer with an external monitor. I'm wishihg to use version 10.04. The problem is, when I plug my laptop into the external monitor with my laptop screen turned either on or off, I do not see the mouse cursor on the external monitor! The mouse cursor is still there, although invisible. If I connect the external monitor to my laptop before swithing both on, the same happens. Is there any solution to make the cursor appear on the monitor?

• Saving more corsor positions (with tput?) in bash terminal

  - by AndreasT

  I know that tput sc saves the current cursor position and tput rc restores it exactly where tput sc was called. The problem is that every time tput sc is called, it overwrites the previous saved position. Is there a way to save more positions, e.g. tput sc pos1 and tput sc pos2 which can be restored with, say, tput rc pos1 and tput rc pos2 respectively? (The solution need not make use of tput, I mentioned it because it's the only command I know that handles cursor position) If not, is there a way to at least save the cursor position locally in a function, so that if a function uses tput sc and then calls another function that runs again tput sc, then each function restores its own saved cursor position when invoking tput rc? Thanks in advance.

• Lost left/right cursor keys in VIM insert mode?

  - by depesz

  When I edit .sql file in VIM, I can't use left/right cursor keys while in insert mode. In normal mode they work just fine. In another file types - they work fine as well. in ~/.vim/ftplugin/sql.vim there is bunch of "iab"s, but not much more. I found out that when running vim with standard vimrc, not-customized, the problem is not existing. What could be wrong? Is there any option that could have been set, that disables some (up and down work) cursor keys in insert mode ?!

• C++ OpenGL trouble trapping cursor in window

  - by ezio160324

  I am using OpenGL and I try to trap my cursor inside my game window (using both SetCursorPos and ClipCursor) But, these conflict with my camera rotation code as my camera is rotated with my mouse. If there is a way to do it, please let me know. If possible, I would be willing to make it so that when the cursor reaches an edge of the screen, it jumps to the opposite edge (though I fear that would also conflict with my camera code).

• What is the equivalent of Oracle’s REF CURSOR in MySQL when using JDBC?

  - by dacracot

  In Oracle I can declare a reference cursor... TYPE t_spool IS REF CURSOR RETURN spool%ROWTYPE; ...and use it to pass a cursor as the return value... FUNCTION end_spool RETURN t_spool AS v_spool t_spool; BEGIN COMMIT; OPEN v_spool FOR SELECT * FROM spool WHERE key = g_spool_key ORDER BY seq; RETURN v_spool; END end_spool; ...and then capture it as a result set using JDBC... private Connection conn; private CallableStatement stmt; private OracleResultSet rset; [...clip...] stmt = conn.prepareCall("{ ? = call " + call + "}"); stmt.registerOutParameter(1, OracleTypes.CURSOR); stmt.execute(); rset = (OracleResultSet)stmt.getObject(1); What is the equivalent in MySQL?

• Show underlying applications mouse cursor when hovering over visible section of my application.

  - by Dylan Vester

  I am writing a WPF application that allows the user to draw over the entire screen when the right mouse button is held down. I use a full screen transparent overlay form to achieve this, however, as I draw lines with the mouse, what's happening is that the portion of my window that contains the line is becoming visible (as expected). The undesired effect of this is that if the line is over a part of another application such as a textbox, or hyperlink, this changes the cursor back to the default cursor my my app (arrow), instead of the other applications desired cursor (IBeam). I want my overlay to be seamless to the user, and just show their drawing path, rather than have any interaction with the mouse cursor. See my example below:

• Black Screen (but with cursor) after wake-up from suspend to RAM

  - by Naseschwarz

  [Lenovo Thinkpad X60] After upgrading to 12.04, first thing I did was get suspend to HDD back, because I don't use my battery a lot. So I did that. After a while (about a week, I upgraded on release, not beta), maybe a week or so, I started getting black screens from time to time after waking it up from suspend to RAM. I never got that problem with suspend to HDD. As it only happens sometimes, I can't reproduce it o.O Sometimes it doesn't happen for a week (daily use, approx 2-6 wake-ups a day), then every single time. The precise symptoms are as follows: normally I got a black screen with my cursor on it, which can be moved, no problems there. I can't interact with the system in any way except for turning it off on the 1/0 button... the weird thing is, the cursor seems to react to what I had opened when going into suspend to RAM, so for instance one day I had writer open and then my cursor was a "I" for most of the screen. I only get this in 12.04, never had any problems with this in 9.04-11.10. Any ideas? Big thx in advance!

• Why does my cursor jump when typing in ubuntu 11.10

  - by Stephen Myall

  When typing in Ubuntu my cursor jumps around and its not application specific. It doesn't matter or Im filing in a web form, writing an e-mail or using LibreOffice or Lyx. Im using a Sony Vaio 64bit machine. i read a previous question (link below) on this subject which indicates it may have something to do with the touchpad settings. as this has occurred in previous Ubuntu distros Im guess it is somekind of hardware issue. How do you turn of the touchpad when typing to avoid the cursor jumping around? I'd be grateful if anyone can make this stop Stephen

• openGL Camera setup for Zoom in/out centered at point under cursor

  - by user3228921

  I am trying to implement a zoom in/out navigation mode in a openGL 3dViewer. I was able to implement zoom functionality centered at screen center just by moving eye towards the center in perspective mode. Now i am trying to do the zoom centered at arbitrary position under the cursor. I am unable to figure out how should i move my camera forward and backward such that point under cursor remains at the same screen coordinates after zoom in/out. Any help would be appreciated. Below are the images which show the desired effect. Just to mention, I am working in a perspective mode with eye target and up vectors to control camera. Same effect i found in google sketchup and 'zoom to mouse position' setting in blender.

• Black screen with blinking cursor after dual boot install 14.04

  - by chillstream

  I have just installed Ubuntu 14.04 on my toshiba laptop along side Windows 7. When the menu comes up to choose which OS to boot into, I can easily boot into Windows 7. I cannot successfully boot into Ubuntu. All I get is a blinking cursor on a black/purple screen. I attempted the nomodeset trick, which was a bit more successful. I got a screen with a lot of code, but then it stopped with a blinking cursor at the bottom and wouldn't load anymore. As a last resort, would returning my laptop to factory settings get rid of linux and the partitions made to the drive? I already did this to my laptop when it was just windows, which is why I thought I might as well try to add Ubuntu. But it's a lengthy process, and if it won't get rid of the partitions and ubuntu, I won't bother. I appreciate any help ~many thanks

• Unable to set mouse cursor JLayeredPane

  - by Ones3k2

  I'm running into a problem that I can't seem to figure out nor find the answer anywhere on the web. I've got a JLayeredPane and when it only has one child Panel I am able to correctly set the cursor using setCursor(). The cursor shows up and everything is fine. But when I add an additional JPanel into the JLayeredPane the cursor no longer shows up for example this works: m_layeredPane = new JLayeredPane(); m_layeredPane.setLayout(new WBLayoutManager()); m_layeredPane.add(m_mediaPanel, new Integer(0)); // m_layeredPane.add(m_whiteboardPanel, new Integer(1)); m_layeredPane.setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR)); // WORKS but this doesn't: m_layeredPane = new JLayeredPane(); m_layeredPane.setLayout(new WBLayoutManager()); m_layeredPane.add(m_mediaPanel, new Integer(0)); m_layeredPane.add(m_whiteboardPanel, new Integer(1)); m_layeredPane.setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR)); // FAILS Anyone know how i can get custom cursors working within a JLayeredPane

• Getting javascript mouse position relative to website prefferably without jQuery

  - by Constructor

  I've found this snippet on Ajaxian, but I can't seem to use the cursor.y (or cursor.x) as a variable and when the function is called as such it does not seem to work. Is there a syntax problem or something else? function getPosition(e) { e = e || window.event; var cursor = {x:0, y:0}; if (e.pageX || e.pageY) { cursor.x = e.pageX; cursor.y = e.pageY; } else { cursor.x = e.clientX + (document.documentElement.scrollLeft || document.body.scrollLeft) - document.documentElement.clientLeft; cursor.y = e.clientY + (document.documentElement.scrollTop || document.body.scrollTop) - document.documentElement.clientTop; } return cursor; } I'd preffer not to use jQuery UI if possible, since I've always thaught of jQuery and librarys as a bit of an overkill for most JS programing.

• Avoid hourglass mouse cursor when calling a web-service?

  - by BigMoose

  I don't know if this is a general web-services issue or just my specific scenario, which is a WPF application with a DispatcherTimer calling a web-service method. Whenever the timer is called, the mouse cursor automatically changes to an hourglass cursor. The processing of the call is very short and happens every 3 seconds, so the user experience is that every 3 seconds the mouse filckers as an hourglass for a split-second and then goes back to the normal cursor representation. How can I avoid this inconvenience? Thanks.
