  • getting emacs to move cursor by words on a Mac

    - by hatorade
    It's supposed to be M + cursor, but any shortcut in emacs using M (escape) on my mac sucks, because every time i need to use it, i need to release M (the escape key) and then press it again. Is there a better shortcut for moving along words in emacs (kind of like ctr + arrow in windows?)

  • wxPython - ListCrtl and SQLite3

    I'm trying to get a SQLite3 DB to populate a wx.ListCrtl. I can get it to print to stdout/stderr without any problem.

  • Windows 7 Busy Icon won't stop spinning

    - by Lynda
    In windows 7 you have the busy icon that is a little blue wheel spinning beside the cursor when it is doing something. It has started to spin for about a second every 3-5 seconds. There is noting running that I can tell on the computer to cause the busy icon. It gets very annoying and I am not sure what to do to get it to stop. Ideas? Running a CPU Usage Gadget says I have less than 5% of the CPU being use and I have over 6GB of RAM free. (I have 8GB total) I am running a 3.6 GHZ AMD FX 4100 processor. EDIT- What I am actually seeing is the working in background pointer (the pointer is still visible beside the busy icon). EDIT 2 - After realizing this happened with the printer installation I turned on the the printer and the busy icon stopped. The printer is setup wirelessly. How do I stop Windows from (I guess) checking for the printer? That is what I assume it is doing. I am using a HP Officejet 8600

  • jquery Setting cursor position in contenteditable div

    - by Mark
    The old version of the question is below, after researching more, I decided to rephrase the question. The problem as before is, I need to focus a contenteditable div without highlighting the text, doing straight up focus highlights the text in Chrome. I realize that people solved this problems in textareas by resetting the caret position in the textarea. How can I do that with a contenteditable element? All the plugins I've tried only works with textareas. Thanks. Old Phrasing of the question: I have a contenteditable element that I want to focus, but only insofar as to place the cursor at the front of the element, rather selecting everything. elem.trigger('focus'); with jquery selects all the text in the entire element in chrome. Firefox behaves correctly, setting the caret at the front of the text. How can I get Chrome to behave the way I want, or is focus perhaps not what I'm looking for. Thanks

  • mouse_event WinAPI call not working when cursor is over Flash

    - by friederbluemle
    Hi, I am writing a small program which can simulate mouse clicks at specified positions. Using the Win32 API call mouse_event like so: [DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)] public static extern void mouse_event(uint dwFlags, uint dx, uint dy, uint dwData, UIntPtr dwExtraInfo); [Flags] public enum MouseEventFlags : uint { LEFTDOWN = 0x00000002, LEFTUP = 0x00000004, MIDDLEDOWN = 0x00000020, MIDDLEUP = 0x00000040, MOVE = 0x00000001, ABSOLUTE = 0x00008000, RIGHTDOWN = 0x00000008, RIGHTUP = 0x00000010 } mouse_event((uint)(MouseEventFlags.LEFTDOWN | MouseEventFlags.LEFTUP), x, y, 0, UIntPtr.Zero); Works perfectly fine, except when the mouse cursor is over a Flash application. Flash seems to ignore the simulated mouse click. What could be the reason for this? And how do I fix it? Thank you!

  • Bash alias to open Vim at last cursor position mark

    - by Pierre LaFayette
    The mark " in Vim takes you to your last cursor position. I want to create an alias that will open my Vim instance and jump to that mark; something which is obviously extremely useful. This works from the command line: $ vim -c "'\"" File.cpp Now I want to make an alias for this: $ alias v='vim -c "'\""' Well that's not going to work! You need to escape the first single quote you say... $ alias v='vim -c "\'\""' Hmm. That didn't work either... So I try a whole lot of variations of single quoted and double quoted madness, bang my head against the table and load up stackoverflow in my browser, and here we are. How do I properly escape this alias?

  • Set focus and carret position in textarea according to mouse position, as if user had clicked

    - by JeanHuguesRobert
    Once a page with a textarea is loaded, I want some textarea to have the focus immediatly if the mouse cursor is inside that textarea. This is the easy part because a onmousehover handler can set the focus. Now, how to I also set the position of the caret? I would like the caret to be where it would be if the user had clicked using the mouse to set the focus/caret. The basic use case is : User clicks on a link and waits (mouse barely moves) A page is delivered, it contains a big textarea only, full of text User types using keyboard Characters are inserted right below the mouse cursor Today the user has to wait until the caret is visible (at the top left of the textarea) and then click to move the caret before typing. Thanks!

  • How to get video file details eg. duration in Android?

    - by spirytus
    I struggle to get specific video file details so duration etc. from the file the files recorded earlier. All I can currently do is to get cursor with all the files, then loop one by one. Cursor cursor = MediaStore.Video.query(getContext().getContentResolver(), MediaStore.Video.Media.EXTERNAL_CONTENT_URI, new String[]{MediaStore.Video.VideoColumns.DURATION,MediaStore.Video.VideoColumns.DATE_TAKEN,MediaStore.Video.VideoColumns.RESOLUTION,MediaStore.Video.VideoColumns.DISPLAY_NAME}); if(cursor.moveToFirst()) while(!cursor.isLast()){ if(cursor.getString(3)==fight.filename) { // do something here } cursor.moveToNext(); } I need however to access details of specific files so I tried to create URI but no luck as cursor returned is always null. Where do I go wrong? Uri uri = Uri.parse(Environment.DIRECTORY_DCIM+"/FightAll_BJJ_Scoring/"+(fight.filename)); Cursor cursor = MediaStore.Video.query(getContext().getContentResolver(), uri, new String[]{MediaStore.Video.VideoColumns.DURATION,MediaStore.Video.VideoColumns.DATE_TAKEN,MediaStore.Video.VideoColumns.RESOLUTION,MediaStore.Video.VideoColumns.DISPLAY_NAME}); // cursor is always null here

  • strange Problem with WPF Textbox stringformat - Cursor moves back

    - by Emad
    I am using WPF 4.0 TextBox and binding. I am using StringFormat to format the number as currency. the XAML looks like this: <TextBox Text="{Binding Path=ValueProperty, ValidatesOnDataErrors=True, ValidatesOnExceptions=True, StringFormat={}{0:C}, UpdateSourceTrigger=PropertyChanged}"> </TextBox> Everything seems to work correctly except for a strange behavior: When for example a user types in 12: right after typing 1, the value in the textbox becomes $1.00 and the weird thing is the the cursor is moved to be between the $ and the 1. So when a user simply types in 12, the result becomes $21.00. How can I fix this strange behavior?

  • Usage CursorLoader without ContentProvider

    - by sealskej
    Android SDK documentation says that startManagingCursor() method is depracated: This method is deprecated. Use the new CursorLoader class with LoaderManager instead; this is also available on older platforms through the Android compatibility package. This method allows the activity to take care of managing the given Cursor's lifecycle for you based on the activity's lifecycle. That is, when the activity is stopped it will automatically call deactivate() on the given Cursor, and when it is later restarted it will call requery() for you. When the activity is destroyed, all managed Cursors will be closed automatically. If you are targeting HONEYCOMB or later, consider instead using LoaderManager instead, available via getLoaderManager() So I would like to use CursorLoader. But how can I use it with custom CursorAdapter and without ContentProvider, when I needs URI in constructor of CursorLoader?

  • Vim open file under cursor

    - by ereOn
    Hi, Let's say I have the following file tree: / include/ library/ a.hpp b.hpp src/ a.cpp b.cpp And the following /src/a.cpp file: #include "a.hpp" #include "b.hpp" I always open Vim at the root directory. So when I want to load a.hpp I do : :tabnew include/library/a.hpp or: :tabnew **/a.hpp I'd like to map <F4> to open the file under the cursor in a new tab, using a recursive search. I tried the following mapping command: :map <F4> :tabnew **/expand("<cfile>")<cr> But obviously, this can't work, as it tries to open the file "/expand(" instead. Any clue on how I could do that ? Thanks.

  • Filter rows from Cursor so they don't show up in ListView

    - by Richard
    I have a Cursor that returns rows I use with a SimpleCursorAdapter to populate a ListView. I would like to filter some of the rows so they don't get displayed in my ListView. I use the data from the rows elsewhere in my Activity so I don't want to change my SQL to filter them with a WHERE clause. What is the best way to keep a row from being displaying in my ListView? Ideally I would check a column in my row and then only add rows to the ListView that satisfy a condition.
