  • How to log out with a command in a gnome-less environment?

    - by octosquidopus
    I installed various window managers (Awesome, dwm, etc.) from which I am not able to log out back to the login screen (gnome-session) in order to switch to another window manager. I need to reboot to do that, which is a waste of time. Question How can you log out via the terminal? didn't work.. dbus-send --session --type=method_call --print-reply --dest=org.gnome.SessionManager /org/gnome/SessionManager org.gnome.SessionManager.Logout uint32:1 ..neither did this: gnome-session-save --force-logout ..nor that: gnome-session-quit --force-logout they all returned: Failed to call logout: The name org.gnome.SessionManager was not provided by any .service files Is there a quick way to log out back into Gnome's session manager from a non-Gnome desktop manager using a terminal emulator? I know that CTRL+ALT+BACKSPACE can be configured to restart X, but I'm looking for the easiest way to log out.

    - by williamtroup
    How can I point at the object of a ExtJS Grid and manually set the height (in pixels)? For example, with this same: var grid = new Ext.grid.GridPanel({ store: store, columns: [ {id:'company',header: 'Company', width: 160, sortable: true, dataIndex: 'company'}, {header: 'Price', width: 75, sortable: true, renderer: 'usMoney', dataIndex: 'price'}, {header: 'Change', width: 75, sortable: true, renderer: change, dataIndex: 'change'}, {header: '% Change', width: 75, sortable: true, renderer: pctChange, dataIndex: 'pctChange'}, {header: 'Last Updated', width: 85, sortable: true, renderer: Ext.util.Format.dateRenderer('m/d/Y'), dataIndex: 'lastChange'} ], stripeRows: true, autoExpandColumn: 'company', height: 350, width: 600, title: 'Array Grid', // config options for stateful behavior stateful: true, stateId: 'grid' }); I would i be able to point at the "grid" object and then set the size of the grid?

  • How can I print-screen just one window and not my entire desktop?

    - by Michael Durrant
    I could swear I've always been able to do alt-printscreen to get 'just that window' but right now I am getting my entire desktop. Any idea why this would be or what I can do to get my ability to do small window screen shots? I've tried a lot of combination with the ctrl, alt, shift and print-screen keys but no luck, nothing happens in response. One option: shift-ctrl print-screen lets me do a selection using a cross hair to size out the screen capture but I don't know where this gets saved. I'm not being given the choice and it's not in Desktop or Pictures. I use an external keyboard, but I've tried using the laptop's own keyboard and no difference. I am running Ubuntu 12.04 and the laptop is a Samsung Ultrabook 900 Update: I rebooted and it "fixed" it - for now. However this is not the first time I've seen this so I'm still curious as to why it happens, what I can do to fix w/o reboot and if other share the same problem.

  • Is there an apt command to download a deb file to the current directory?

    - by Lekensteyn
    I am often interested in the installation triggers (postinst, postrm) or certain parts (/usr/share or /etc) of packages. Currently, I am running the next command to retrieve the source code: apt-get source [package-name] The downside is, this file is often much bigger than the binary package and does not reflect the installation tree. Right now, I am downloading the packages through http://packages.ubuntu.com/: Search for [package-name] Select the package Click on amd64/i386 for download Download the actual file This takes too long for me and as someone who really likes the shell, I would like to do something like the next (imaginary) command: apt-get get-deb-file [package-name] I could not find something like this in the apt-get manual page. The most close I found was the --download-only switch, but this puts the package in /var/cache/apt/archives (which requires root permissions) and not in the current directory.

  • Access DB Transaction on insert or updating

    - by Raju Gujarati
    I am going to implement the database access layer of the Window application using C#. The database (.accdb) is located to the project files. When it comes to two notebooks (clients) connecting to one access database through switches, it throws DBConcurrency Exception Error. My target is to check the timestamp of the sql executed first and then run the sql . Would you please provide me some guidelines to achieve this ? The below is my code protected void btnTransaction_Click(object sender, EventArgs e) { string custID = txtID.Text; string CompName = txtCompany.Text; string contact = txtContact.Text; string city = txtCity.Text; string connString = ConfigurationManager.ConnectionStrings["CustomersDatabase"].ConnectionString; OleDbConnection connection = new OleDbConnection(connString); connection.Open(); OleDbCommand command = new OleDbCommand(); command.Connection = connection; OleDbTransaction transaction = connection.BeginTransaction(); command.Transaction = transaction; try { command.CommandText = "INSERT INTO Customers(CustomerID, CompanyName, ContactName, City, Country) VALUES(@CustomerID, @CompanyName, @ContactName, @City, @Country)"; command.CommandType = CommandType.Text; command.Parameters.AddWithValue("@CustomerID", custID); command.Parameters.AddWithValue("@CompanyName", CompName); command.Parameters.AddWithValue("@ContactName", contact); command.Parameters.AddWithValue("@City", city); command.ExecuteNonQuery(); command.CommandText = "UPDATE Customers SET ContactName = @ContactName2 WHERE CustomerID = @CustomerID2"; command.CommandType = CommandType.Text; command.Parameters.AddWithValue("@CustomerID2", custIDUpdate); command.Parameters.AddWithValue("@ContactName2", contactUpdate); command.ExecuteNonQuery(); adapter.Fill(table); GridView1.DataSource = table; GridView1.DataBind(); transaction.Commit(); lblMessage.Text = "Transaction successfully completed"; } catch (Exception ex) { transaction.Rollback(); lblMessage.Text = "Transaction is not completed"; } finally { connection.Close(); } }

  • Is it possible to programmatically prevent a game from pausing when its window loses focus?

    - by user836045
    I'm playing Skyrim in windowed mode and I am trying to create a bot for this game for personal use. I would like to have the bot play the game in the background, while I do other things, the only problem is that the game window pauses when it loses focus. Is there a way to make the Skyrim process think that it still has the focus, so it continues to run while I do something else on another window? I'm not a windows programming expert but would this be possible if I could somehow intercept the message that says unfocused or minimized to the process, and thus let the process think its still focused? I think Skyrim uses directx, so is it possible to come up with a solution from that end?

  • Second click on a launcher icon with more than one window open doesn't do a scale of that application

    - by Eastsun
    In unity, if I click an icon in the launcher with multiple windows open it doesn't show me all open windows for that application. However, this works in unity2d. I known there have a same question asked before: here! But I think my condition is not as same as the previous question. ubuntu 12.04 64-bit unity 5.16.0 kernel linux 3.2.0-33-generic gnome 3.4.2 Edit I just find a interest thing: There are four workspace, label it as A, B, C, D. If I firstly open two windows of firefox in A, as I mentioned above, second click on the firefox icon does nothing. But after I open a window of firefox in B, the second click on the firefox icon in workspace A magically works!! And then, I open two terminal in workspace C, second click doesnot work until I open another terminal window in D. So, it seems that the second click only work if the application be opened more than one workspace.

  • system-wide hook for 64-bit operating systems

    - by strDisplayName
    Hey everybody I want to perform a system-wide hook (using SetWindowHook) on a 64bit operating system. I know that 64bit processes (= proc64) can load only 64bit dlls (= dll64) and 32bit processes (= proc32) can load only 32bit dlls (= dll32). Currently I am planning to call SetWindowHook twice, once with dll32 and once with dll64, expecting that proc64s will load dll64 and proc32s will load dll32 (while dll32 for proc64s and dll64 for proc32s will fail). Is that the correct way to do that, or is there a "more correct" way to do that? Thanks! :-)

  • How to create animated sliding windows/tabs menu?

    - by Forte
    I have created navigation menu in YUI 2.8 as below : I have also animated tabs using CSS transitions. CSS transitions are not widely supported by browsers and my animations are not working in Opera, IE etc. Since i'm already using YUI 2.8 on that page, can somebody tell me how do i animate those tabs? When i click on any tab, it should expand in vertical dimension smoothly (animated). Below are the properties of tabs which are going to change when i select any tab (Below properties of tabs should be animated) : Paddings Margins Background-Color Borders Please note in above image : There is little space left on right side in case #1 when 1st tab is selected. In case #2 and case #3 there is space left on left as well as right side. In case #4, there is some space left on left side when last tab is selected.

  • What is the easiest and fastest way to display an SDL_Surface in a window with SDL2?

    - by Semmu
    I would like to have an SDL_Surface representing the contents of the window, just like in the old days with SDL1.2. What is the best and fastest way to do it in SDL2? What I found is that I need an SDL_Window, an SDL_Renderer for that window, an SDL_Texture to render, and an SDL_Surface to create a texture from. This seems a bit too much to me, since I just want to display a single image on the screen. Not to mention the impact on the performance. On my machine (Lenovo Y510p laptop) this whole procedure takes 9ms, without any memory allocation, only using pre-allocated variables and totally black SDL_Surface. Is there a way I could speed up things?
