  • How do I program a hardware button on my laptop?

    - by daniel11
    So I have a set of touch screen buttons on the top of my laptop's keyboard, (one turns on power save mode, one disables/enables the mouse touch pad, one toggles the wifi adapter, and two turns the volume up/down). However there's another one that opened a file backup utility that came with my laptop. Since I bought my laptop, I've uninstalled that utility, rendering this button useless. Would it be possible to reprogram that button to open another file or program on my computer? And if so, what are the requirements and how would I go about doing it? Thanks in advance!

  • FFMPEG Splitting MP4 with Same Quality

    - by Pragmatic
    I have one large MP4 file. I am attempting to split it into smaller files. ffmpeg -i largefile.mp4 -sameq -ss 00:00:00 -t 00:50:00 smallfile.mp4 I thought using -sameq would keep the same quality settings. However, I must not understand what that does. I'm looking to keep the same quality (audio/video) and compression with the split files. However, this setting makes the split files much larger. What flag(s) do I need to set to keep the same quality and attributes in the split files while maintaining the same quality to size ratio? For instance if my original file is about 12 GB and is 1920x1080 with a bitrate of 10617kbps and a framerate of 23 frames/sec and 6 channel audio with 317kbps, I would like the split files to be the same only a third of this size (if i split it into three pieces).

  • Multi Threading - How to split the tasks

    - by Motig
    if I have a game engine with the basic 'game engine' components, what is the best way to 'split' the tasks with a multi-threaded approach? Assuming I have the standard components of: Rendering Physics Scripts Networking And a quad-core, I see two ways of multi-threading: Option A ('Vertical'): Using this approach I can allow one core for each component of the engine; e.g. one core for the Rendering task, one for the Physics, etc. Advantages: I do not need to worry about thread-safety within each component I can take advantage of special optimizations provided for single-threaded access (e.g. DirectX offers a flag that can be set to tell it that you will only use single-threading) Option B ('Horizontal'): Using this approach, each task may be split up into 1 <= n <= numCores threads, and executed simultaneously, one after the other. Advantages: Allows for work-sharing, i.e. each thread can take over work still remaining as the others are still processing I can take advantage of libraries that are designed for multi-threading (i.e. ... DirectX) I think, in retrospect, I would pick Option B, but I wanted to hear you guys' thoughts on the matter.

  • Delete button in Ubuntu One Notes

    - by Jean MC13
    For the whishlist... The 'delete button' in Ubuntu One Notes is exactly in the same place as the 'save' button. So I saved a long note, but as my finger clicked two times on the save button, the second click was on the 'delete' one ! Lost without return possible. <:-(( This annoying feature could easily be changed : - put the delete button in another place - before deleting : ask for confirmation - offer a way to cancel ('undelete' function)

  • Load HTML frames in a specific order without back button problems?

    - by Joergen Bech
    I have a web page that uses a frameset. Due to scripting and object dependencies, I need to load the frames in a specific order. I have used this example as a template: The JavaScript Source: Navigation: Frames Load Order This loads an empty page in place of the page I need to load last, then replaces it with the correct page after the first page has loaded. However: I also need to use the browser Back button. If you run the sample at the above link, let both frames load, then click the Back button, the top frame reverts to the temporary blank page. It is then necessary to click the Back button again to navigate to the page before the frameset. Is there a way to force frames to load in a specific order without this Back button behavior - or a way to force the Back button to skip the empty page? This needs to work with Internet Explorer 6 and 7 and preferably with Firefox 3 as well.

  • Why doesn't Python's `re.split()` split on zero-length matches?

    - by Tim Pietzcker
    One particular quirk of the (otherwise quite powerful) re module in Python is that re.split() will never split a string on a zero-length match, for example if I want to split a string along word boundaries: >>> re.split(r"\s+|\b", "Split along words, preserve punctuation!") ['Split', 'along', 'words,', 'preserve', 'punctuation!'] instead of ['', 'Split', 'along', 'words', ',', 'preserve', 'punctuation', '!'] Why does it have this limitation? Is it by design? Do other regex flavors behave like this?

  • does jQuery UI have a way to achieve this Flash button's functionality?

    - by Tim
    There's a button in Flash which looks something like a jQuery SplitButton. The Flash button consists of two parts, the text and the icon. [text portion] [v] I have used it to display string search operators for the user: equals, starts with, ends with, contains. In Flash, when the icon is clicked, the text-area drops down a list of choices; it would look like this: [ ] [v] equals starts with ends with contains And when the user makes a choice from the list, the choice is displayed in the text area of the button and the list rolls up. [ starts with ] [v] I'm trying to convert my Flash app and am hoping to come up with a counterpart to this functionality. For space considerations on the form, a radio-button-group would be less than ideal. That's the major virtue of this Flash button -- it's very economical in its use of screen real-estate. Thanks for any answers/suggestions.

  • ActionScript - One Button Limit (Exclusive Touch) For Mobile Devices?

    - by TheDarkIn1978
    two years ago, when i was developing an application for the iPhone, i used the following built-in system method on all of my buttons: [button setExclusiveTouch:YES]; essentially, if you had many buttons on screen, this method insured that the application wouldn't be permitted do crazy things when several button events firing at the same time. problematic: ButtonA and ButtonB are available. each button has a mouse up event which fire a specific reorganization/layout of the UI. if both button's events are fired at the same time, their events will likely conflict, causing a strange new layout, perhaps a runtime error. solution: application buttons cancel any current pending mouse up events when said button enters mouse down. private function mouseDownEventHandler(evt:MouseEvent):void { //if other buttons are currently in a mouse down state ready to fire //a mouse up event, cancel them all here. } of course it's simple to manually handle this if there are only a few buttons on stage, but managing buttons becomes more and more complicated / bug-prone if there are several / many buttons available. is there a convenience method available in AIR specifically for this functionality?

  • Overridden button control escaping content. How to stop it?

    - by RemotecUk
    Hi, I've got an ASP.Net button control that I have overridden to provide different functionality. the code looks as follows.. I'm overriding the Render method to surround the control with an <a>... /// <summary> /// Render Method /// </summary> /// <param name="writer"></param> protected override void Render(HtmlTextWriter writer) { base.CssClass = "euva-button-decorated"; writer.Write("<a class=\"euva-button\">"); base.Render(writer); writer.Write("</a>"); } When I check the generated source on the page, I find that where ASP.Net has injected its click handler it does the following... <a class="euva-button"><input type="submit" name="TestButton" value="Test Button" onclick="clickOnce(this);WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions(&quot;TestButton&quot;, &quot;&quot;, true, &quot;&quot;, &quot;&quot;, false, false))" id="TestButton" class="euva-button-decorated" /></a> ... it seems to be escaping the output for the double quotes which means that the browser cannot understand the javascript. How do I make the render method not escape the injected ASP.Net client click handler ?? Note I also have my own client click handler which is declared declaratively in the page mark-up.

  • can we use both custom button and inbuilt button in datagridview

    - by Srikanth Mattihalli

I am handling the up down buttons by raising events in rowcommand and the code is as below string command = e.CommandName; Response.Write(e.CommandArgument.ToString()); int index = Convert.ToInt32(e.CommandArgument.ToString()); int count = GridView1.Rows.Count; int keyValue = Convert.ToInt32(GridView1.Rows[index].Cells1.Text); string value = GridView1.Rows[index].Cells[4].Text; SqlConnection conn = new SqlConnection(SqlDataSource1.ConnectionString); SqlCommand cmd = new SqlCommand(); if (command == "up") { if (index > 0) { index = index - 1; int keyValue1 = Convert.ToInt32(GridView1.Rows[index].Cells[1].Text); string value1 = GridView1.Rows[index].Cells[4].Text; cmd.Connection = conn; cmd.CommandText = "UPDATE [category] SET [order_id] = '" + value + "' WHERE [category_id]=" + keyValue1 + ";UPDATE [category] SET [order_id] = '" + value1 + "' WHERE [category_id]=" + keyValue + ";"; conn.Open(); cmd.ExecuteNonQuery(); conn.Close(); } } else if (command == "down") { if (index < count - 1) { index = index + 1; int keyValue1 = Convert.ToInt32(GridView1.Rows[index].Cells[1].Text); string value1 = GridView1.Rows[index].Cells[4].Text; cmd.Connection = conn; cmd.CommandText = "UPDATE [category] SET [order_id] = '" + value + "' WHERE [category_id]=" + keyValue1 + ";UPDATE [category] SET [order_id] = '" + value1 + "' WHERE [category_id]=" + keyValue + ";"; conn.Open(); cmd.ExecuteNonQuery(); conn.Close(); } } Response.Redirect("Default.aspx"); Designer file " DeleteCommand="DELETE FROM [category] WHERE [category_id] = @category_id" InsertCommand="INSERT INTO [category] ([categoryname], [navigation_url], [order_id]) VALUES (@categoryname, @navigation_url, @order_id)" SelectCommand="SELECT * FROM [category] order by order_id" UpdateCommand="UPDATE [category] SET [categoryname] = @categoryname, [navigation_url] = @navigation_url, [order_id] = @order_id WHERE [category_id] = @category_id" After this my edit,delete and paging is not working bcoz of event conflicts. Can anyone plz help me on this, so that i will be able to use both custom buttons(up and down) and edit,delete and paging features.

  • Excel or Access: how to group several lines in a table and insert contents in columns? ("split column")

    - by Martin
    I have a table containing data of sold products (shown in the example on the left): Columns: Number of the order Product Name Attribute - specifies what is given in the following field "value", e. g. Customer Name or Product Variant Value - is the value of the Attribute Count - is the number of products of this variant sold in the order That means: Product B has 2 variants "c" and "d" Note that in Order 1 Product B was sold in Variant d only, because the letter "N" in field "D4" means "none". Note, that in OrdnerNo 3 Product B was sold only in Variant c, because for Variant d field "D9" is "N"!! This is confusing, but it is the structure of the original data (which I can not change). I need a way to convert the table on the left in a table like that on the right: one line for each product type Order Number Product Name Customer Name Count (number of products sold in this order) Variant - this is the problem, as it has to be filled with the So all rows with the same OrderNo and same product have to be grouped in to one, and I hope it is clear what I need. I tried to do it with Pivot Tables, but that fails, as the Count is always in each line, no matter if it has Value "N" or not and for the products without variants there is only one line for each order, however for products with variants there are several... So how could I create the right table with a VBA macro in MS Excel or maybe there is a trick in MS Access to do it directly or with an SQL query?

  • Adding a button bar at the bottom of ListView upon checkbox select (as in gmail app)??

    - by elto
    I have a ListView with custom adapter. In each row there is a checkbox and couple of textviews. I want user to give option to delete the check marked items, so as soon as soon clicks on one of the checkbox, I want a button bar to slide in from the bottom and stay at the bottom regardless of listview scroll. This is something like the email app behavior of Motorola Cliq and to some extent gmail app itself. I have tried adding a relativelayout (containing buttons) below the listview, which has visibility set to gone initially, but as soon as user checks a button, the visibility changes to "visible". I have added a slide-in animation to it too. It is working but problem is that it is overlapping the last element of the listview which user can not checkmark if the button bar has already become visible. So I tried to set the bottom margin of the listview equal to the height of the button bar when I'm changing the button bar visibility, which solves the problem of overlap, but now the checkbox behavior has gone weird. Clicking on one checkmark tries to checkmark another checkmark in the list for some weird reason. I noticed that this happens because as soon as I change the listview margin, list redraws itself, and during this new call to getView() method of adapter, things mess up. I wanted to ask if anyone has done something like this. What is the best method to add such button bar below list while keeping the slide-in animation intact. Also, What is the footer-view of listview and can that solve my problem?

  • How can i change background image of a button when hover or click in XAML for Windows 8?

    - by apero
    I got a question about changing the background image of a button when it's clicked. I tried searching on google but i couldn't find something that worked for me. Well here's my code <Button Grid.Column="0" Grid.Row="0" x:Name="btnHome" VerticalAlignment="Stretch" BorderBrush="{x:Null}" HorizontalAlignment="Stretch" Click="btnHome_Click" PointerEntered="btnHome_PointerEntered"> <Button.Template> <ControlTemplate TargetType="Button"> <Border x:Name="RootElement"> <VisualStateManager.VisualStateGroups> <VisualStateGroup x:Name="CommonStates"> <VisualState x:Name="MouseOver"> <Storyboard> //I want my background change here </Storyboard> </VisualState> <VisualState x:Name="Pressed"> <Storyboard> //And here </Storyboard> </VisualState> </VisualStateGroup> </VisualStateManager.VisualStateGroups> <Border.Background> <ImageBrush ImageSource="images/back_button.png"/> </Border.Background> </Border> </ControlTemplate> </Button.Template> </Button> i also tried this private void btnHome_PointerEntered(object sender, PointerRoutedEventArgs e) { BitmapImage bmp = new BitmapImage(); Uri u = new Uri("ms-appx:images/back_button_mouseover.png", UriKind.RelativeOrAbsolute); bmp.UriSource = u; ImageBrush i = new ImageBrush(); i.ImageSource = bmp; btnHome.Background = i; } But unfortunately this worked neither

  • Custom Image Button and Radio/Toggle Button from Common Base Class

    - by Wonko the Sane
    Hi All, I would like to create a set of custom controls that are basically image buttons (it's a little more complex than that, but that's the underlying effect I'm going for) that I've seen a few different examples for. However, I would like to further extend that to also allow radio/toggle buttons. What I'd like to do is have a common abstract class called ImageButtonBase that has default implementations for ImageSource and Text, etc. That makes a regular ImageButton implementation pretty easy. The issue I am having is creating the RadioButton flavor of it. As I see it, there are at least three options: It would be easy to create something that derives from RadioButton, but then I can't use the abstract class I've created. I could change the abstract class to an interface, but then I lose the abstract implementations, and will in fact have duplication of code. I could derive from my abstract class, and re-implement the RadioButton-type properties and events (IsChecked, GroupName, etc.), but that certainly doesn't seem like a great idea. Note: I have seen http://stackoverflow.com/questions/2362641/how-to-get-a-group-of-toggle-buttons-to-act-like-radio-buttons-in-wpf, but what I want to do is a little more complex. I'm just wondering if anybody has an example of an implementation, or something that might be adapted to this kind of scenario. I can see pros and cons of each of the ideas above, but each comes with potential pitfalls. Thanks, wTs

  • How to animate button text? (loading type of animation) - jquery?

    - by AL
    I got something that I want to do and want to see what you guys think and how can it be implemented. I got a form in a page and the form will submit to itself to perform some process (run functions) in a class. Upon clicking the submit button, I want to animate the button text to “SUBMIT .” -> “SUBMIT ..” -> “SUBMIT …” -> “SUBMIT ….” -> “SUBMIT ….” and then back again. Sort of “animate” the button text. Once the whole process is done, the button text will goes back to be “SUBMIT” text again. Please note that I am not looking for image button solution, meaning that I do not want to implement gif animated button image. Anyone done this before or know how this can be done? I have google but seems nothing of this kind to be found. Thanks! AL

  • Deletes that Split Pages and Forwarded Ghosts

    - by Paul White
    Can DELETE operations cause pages to split? Yes. It sounds counter-intuitive on the face of it; deleting rows frees up space on a page, and page splitting occurs when a page needs additional space. Nevertheless, there are circumstances when deleting rows causes them to expand before they can be deleted. The mechanism at work here is row versioning (extract from Books Online below): Isolation Levels The relationship between row-versioning isolation levels (the first bullet point) and page splits is...(read more)

  • Make Your Own Windows 8 Start Button with Zero Memory Usage

    - by The Geek
    After using Windows 8 for a while, I’ve come to the conclusion that removing the Start button from the Taskbar was a huge mistake. Here’s how to make your own “Start” button that brings up the Metro Start screen—but doesn’t waste any memory at all. What we’ll be doing is pretty simple—create a script that simulates pressing the Windows key button, make it into an executable, assign an icon, and pin it to the taskbar so that it sorta looks like the Start button, and works the same way. Since nothing is running, no RAM is wasted.

  • Make the middle mouse button behave as a double-click in Windows 7?

    - by Geoff Olynyk
    What is the best, lightest-weight way to make the middle mouse button (i.e. clicking the scroll wheel) behave as a double-left-click in Windows 7? I want this to be universal, so that other programs don't ever see the middle-click, they just see a double-left-click. I used to do it under Windows XP with Logitech SetPoint drivers but it was always an ugly solution - installing a huge ( 50 MB!) binary just to enable one simple little bit of functionality.
