  • Adapting Android Bluetooth Chat for multiple devices

    - by Megh
    Hello, I'm doing a college project on Bluetooth for Android, and I'm trying to understand how to manage communication between multiple connected devices. Eventually I'm going to develop a multiplayer Bluetooth Game. Currently I've adapted Android's sample app BluetoothChat to connect my three Nexxus One phones. 1 connects to 2 who connects to 3 1 sends its messages successfully to 2. 3 sends its messages successfully to 2 as well. 2 can send its messages successfully to 1 and 3, as it shares a ConnectedThread with both. But I can't figure out how to handle getting communication from 1 to 3. Does anyone have any examples of communication between multiple devices or has done this themselves? Thanks

  • Error with global variable in php not extending to included php file

    - by phileaton
    I have an html file that calls has a php section in the header like so: $page = basename($_SERVER['PHP_SELF']); Now further down in the html file I have a included footer like so: <?php include("footer.php"); ?> In this script I am referencing the $page variable, but it doesn't find it. I tried echoing the variable and nothing happened. When I place the basename() code in the footer.php file though, it handled it fine. I'd like to be efficient with the coding, so how can I get the footer.php file to get that $page variable? Is there a better way to do this than including the $page variable twice?

  • jquery toggle+paginate+multiple instances

    - by mark
    Hi, I'm a jquery newbie - wanted to ask what might be the best strategy for achieving what I am after as I think it uses a mix of jquery functions : If list of items exceeds 5 items a 'more' link appears which when toggled will reveal the rest of the items. If items list is 5 or less no 'more' link is shown. Hide button also at bottom of long full revealed list. (perhaps this is toggle+pagination?) And then also that this can be used in multiple instances, as it is for multiple category menu's.(to be used in typical indexhibit websites structure like http://mikeyburton.com/) link 1 link 2 link 3 link 4 link 5 link 6 link 7 link 8 more Any help or links greatly appreciated.

  • Handling multiple accounts in Android app

    - by bebeTech
    I would like to build an application that caters for multiple accounts (eg. home, work) and account types (e.g. ISP, VoIP, Mobile). Essentially, I would like to get the user to create the accounts they want and then have all the accounts listed on the start page grouped by type. For example: ISP: - Home - Work Mobile: - Mum - Dad When you click on the account, it would take you to another screen where I do a bunch of calcs and display the results. I currently do this via multiple apps but am looking at consolidating into the one app. I am just not sure where to start or how I go about achieving this? The way the Contacts app works is a good example of what I am wanting to do.

  • Bash Color Variable Output

    - by drewrockshard
    I've got a variable, let's say $x and it holds the value of website.com. I want to be able to call the variable and apply shell color to it like so: echo -e '\033[1;32m$x:\033[0m'; The problem is not the color, however, it's how the script it interpretting the output. So the output I'm getting is: $x: I need the output to obviously be the string in the variable, and not the variable name. Is there any way around this issue?

  • xargs command works on ubuntu, but not mac

    - by Corey Hart
    I have the following line of code that I use to update my personal date variable in my projects to todays current date. This line works in Ubuntu's terminal, but the Mac terminal seems to be far behind. Unfortunately, I copied this snippet from some site, so I'm not sure how it exactly works. Suggestions? grep -ilr --exclude=revar.sh --exclude=README.md "[DATE]" * | grep -v .git | xargs -i@ sed -i "s/\[DATE\]/${today}/g" @

  • Passing CMD Results to Variable in a Batch File

    - by TripleNad
    I am trying to install an application and a group of services using PSTools, but I want to take into account that the computer I am trying to connect to may be turned off or on a different network, which is not reachable from the internal network. Basically if the machine is not able to be accessed through the admin share, this is the message that I am getting: Couldn't access MachineName: The network path was not found. Make sure that the default admin$ share is enabled on MachineName. This is the syntax I am using to try to capture the "Error Message" and then report back that if installation was successful or not (depending on if it can contact the machine) @echo off set /p name=What is the machine name?: psexec.exe \\\%name% -u *useraccount* -p *password* \\\ServerName\installation.bat FOR /F "tokens=*" %%A IN ('COMMAND ^| FIND "Couldn't access"') DO SET Error=%%A If "%Error%"=="Couldn't access" ECHO Installation Failed. Else ECHO Installtion complete. Pause exit Currently it hangs right at the point it's defining the Error Variable. Can't quite figure out what I am going wrong here.

  • Best Practices for Working with Multiple Monitors in Visual Studio 2010

    - by Clever Human
    Now that Visual Studio 2010 has support for multiple monitors, I am curious how other people have their environments arranged. I have yet to come up with an arrangement that I am really satisfied with. The current best I have come up with for my 2 monitor system is to have all code windows detached. Then, on my primary monitor, I am able to have two code windows side by side (using the Windows 7 keyboard shortcuts WinKey+LeftArrow and WinKey+RightArrow.) On my secondary monitor I put the rest of the IDE with all of the tool windows that are normally on the bottom (errors list, find window, call stack, etc...) docked where the code windows normally go. I've also tried having all those things detached and having almost nothing in the IDE proper. The problems with this layout are: Newly opened code windows always open in the IDE, not on top of one of the detached windows. Detached code windows do not remember their exact placement from session to session (they are slightly off, having me to use the winkey + arrow key shortcut again and again for each window. There seems to be no way to have the code panes aware that they are on top of one another (IE -- multiple tabs.) The CTRL+TAB shortcut always displays on top of the IDE proper. The Code Panes are always "on top" of (children of) the IDE. So clicking on any code pane brings the IDE to the foreground, even when I care only about that code pane, and not the IDE. Other more minor issues... What would go a long way to making this better is having the code panes detach such that they are tab strips that can have other code panes docked within them. The new multi-monitor support in VS2010 is good, but it still seems really lacking. Can these issues be solved with an add-in? If so, is anyone aware of one? Is there a better way to work with the IDE on multiple monitors than what I am doing? NOTE: While this question is subjective (there is certainly no "this is the best way and that's final" answer) I'd really like to know possibly better methods of working with the IDE than what I have come up with. The intent is not to start a "mine's best" flame war.

  • using key/value collection in session

    - by jumpdart
    Question: What is a good datatype to keep in session for a large collection of keys and values to frequently reference and update? Application: Updating an old .NET web app with a million pages and grids to have all the grids maintain their sort. They currently access helper code to format themselves graphically on load and on sort. I figured I could add to that code to check for a key based on the page and grid id in a collection in session to see if it has a previous expression on load. and the on sort update/add its appropriate item in the collection. Thoughts? Dictionary vs NameValueCollection

  • Adding extra data to a Variable

    - by DogPooOnYourShoe
    Right now, my code plucks out only one value using Mysql. So I thought I might aswell add each found result to a variable, however I dont know how to do this. This must be a very basic question, but I cant find a answer for it echo '<table border="1">'; echo "<tr><td><b>Surname</b></td><td><b>Title/Name</b></td><td><b>Numbers</b></td><td><b>Telephone</b></td><td><b>Edit</b></td><td><b>Del</b></td></tr>\n"; while ($row= mysql_fetch_array($result)) { $Surname = $row["Surname"]; $Title = $row["TitleName"]; $Email = $row["Email"]; $Telephone = $row["Telephone"]; $id = $row["id"]; $MooringNumbers = $row['Number']; $Assignedto['AssignedTo']; } $MooringQuery = "select * FROM mooring WHERE AssignedTo='$id'"; $MooringResult = mysql_query($MooringQuery) or die("Couldn't execute query"); while ($row1= mysql_fetch_array($MooringResult)) { $AssignedTo = $row1["AssignedTo"]; $MooringNumbers = $row1["Number"]; echo '<tr><td>' .$Surname.'</td><td>'.$Title.'</td><td>'.$MooringNumbers .

  • Multiple things at once (Threads?)

    - by Jonathan
    All, What is a really simple way of having a program do more than one thing at once, even if the computer does not necessarily have multiple 'cores'. Can I do this by creating more than one Thread? My goal is to be able to have two computers networked (through Sockets) to respond to each-other's requests, while my program will at the same time be able to be managing a UI. I want the server to potentially handle more than one client at the same time as well. My understanding is that the communication is done with BufferedReader.readLine() and PrintWriter.println(). My problem is that I want the server to be waiting on multiple readLine() requests, and also be doing other things. How do I handle this? Many thanks, Jonathan

  • In need of a Smarter Environmental Package Configuration

    - by Jeremy Liberman
    I am trying to set up a package template in SSIS, following the Wrox Programmer to Programmer book, SQL Server 2008 Integration Services: Problem - Design - Solution. I'm really liking this book even though it is 2008 and we're using SQL Server 2005. I've got a working package template that uses an Indirect XML package configuration to identify what environment (local developer, dev, QA, production, etc) the package is being run in. That locates the SQL Server package configuration for the environment. That set-up is great and all except for the environment variable at the very front of it all. My team would prefer it if the package could use the same environment resource locator as all our other applications and tools use, so we don't two environment markers with essentially the same information in them. Normally we look up a registry key in HKey_Local_Machine but the Registry Package Configuration type only lets you look up the HKey_Current_User registries. My first thought was to write a new Package Configuration Type class that extends the Registry type; after all we'd had such luck writing our own custom log provider. SSIS is super extendable, right? So there doesn't seem to be a way to write your own Package Configuration Types. Is there still some way I can configure my SSIS SQL Server package configuration from a HKLM registry key connection string? If this is not possible, what other workarounds are available? My idea is to write a PowerShell script that will create/modify the Environment Variable that the package will use by fetching the connection string from the registry. This way there's still two markers, but at least then it's automatically maintained and automated. Is this kind of workaround necessary? Thank you for your time.

  • Variable type for Application on Time Events [on hold]

    - by user2931226
    Been Trying to figure out how to go about setting a Variable for some Application On Time events, But still not confident to do it. These events (Macro's) get called by another Macro then they wait for 10 - 20 minutes, then they don't Run. So have read that (EarliestTime argument) should be assigned to a variable to store it other wise it looses it when other things are running Help appreciated Thanks Sub settimers() Application.OnTime TimeValue(Range("$X$9").Text), "StartBlink" Application.OnTime TimeValue(Range("$W$11").Text), "StopBlink" End Sub

  • C++ Beginner - Trouble using structs and constants!

    - by Francisco P.
    Hello everyone! I am currently working on a simple Scrabble implementation for a college project. I can't get a part of it to work, though! Check this out: My board.h: http://pastebin.com/J9t8VvvB The subroutine where the error lies: //Following snippet contained in board.cpp //I believe the function is self-explanatory... //Pos is a struct containing a char, y, a int, x and an orientation, o, which is not //used in this particular case void Board::showBoard() { Pos temp; temp.o = 0; for (temp.y = 'A'; temp.y < (65 + TOTAL_COLUMNS); ++temp.y) { for (temp.x = 1; temp-x < (1 + TOTAL_ROWS); ++temp.x) { cout << _matrix[temp].getContents(); } cout << endl; } } The errors returned on compile time: http://pastebin.com/bZv7fggq How come the error states that I am trying to compare two Pos when I am comparing chars and ints? I also really can't place these other errors... Thanks for your time!

  • How to handle multiple projects in a small team

    - by meo
    We just started to use scrum for our project management. We are a very small team (2 developers, 1 UI/Web-deisgner ) and we have a lot of running projects at once. How do you handle having multiple projects running at once in the scrum model? Most of the time we have a main projects and some small ones. How do you combine multiple sprints efficiently? PS: I'm not sure stackoverflow is the right place to ask this kind of question, i hope there is a scrum master out there reading this.
