  • Excel: How to Compare Column Values in a Row

    - by spazzie
    I have a bunch of comparison data and a lot of entries being compared. As an example, say my sheet looks like this, give or take a few columns: Item Price1 Quantity1 Price2 Quantity2 Price3 Quantity3 001 $123 12 $456 24 $789 48 002 $100 95 $200 5 $300 51 For each item (row), I want to be able to look at all of the Quantity columns and find which one has the highest quantity. Ideally I'd be able to run a condition of some sort on the entire excel sheet at once, and it would highlight in red the highest quantity. So the results would be a red "48" (qty3) for Item 001 and a red "95" (qty1) for Item 002. Only the color would change, not any data, and no new rows would need to be created. Let me know if you need more info

  • Easiest way to get feedback from an EC2 instance

    - by Sanity
    I need to run a script on an ec2 instance once a day, and I'd like to have some easy way for it to let me know if something went wrong. I would prefer not to have to modify the original image, which is a recent version of Ubuntu, so ideally I'd like to do all setup in the script I pass to the Ubuntu instance through the ec2-run-instances command. I've considered creating a gmail account for it, and letting it send email through that - but the setup was rather involved, with certificates and such things. I've looked at using the gist API, but anything uploaded through it is public. The Google command line tool also appears quite complicated to set up. Is there some easier way to do this?

  • What differences should I know? I just upgraded to 13.10 from 10.10 [on hold]

    - by test
    I ran Ubuntu 10.10 for a long time because I liked the menu style. The change in GUI with the upgrades drove me nuts but I finally gave in and downloaded Saucy Salamander 13.10 x64. It's a fresh install running as a virtual machine guest in VMWare Workstation 9 on a Windows 7 x64 host. Well it looks like all those icons are still there on the side which I would be OK with if there were some way to bring back my menus. I have no organized way of accessing things now, or do I? That is the purpose for this question, maybe there is some functionality I just can't find but is there. Also all my fine tuning was gone. I used to be able to change DPI but that's gone. I went ahead and installed Unity Tweak Tool via sudo apt-get install unity-tweak-tool but I couldn't find an icon for it after I installed it.. because again no menu. So I did a search for it and found it there. I've changed the font and which side the window buttons appear on which is good enough for now. Anyway... any suggestions you may have for me I'm game. I'm a Windows 7 user primarily but I use Ubuntu every once in a while. I really liked the old style where everything was categorized like for Applications there was Accessories, Games, Graphics, Internet, Office, Sound & Video, Wine.

  • sqlserver.exe uses 100% CPU

    - by Markus
    I've created an application (asp.net) that once a day syncs an entire database through XML-files. The sync first creates an transaction and then clears the databases tables and then starts to parse and insert the new rows into the database. When all the parsing is complete it commits the transaction. This works fine on a SQL Server 2005 (on another machine), but on SQL Server 2005 Express, the process starts to use 100% CPU after a while, and as I log the inserts being made I can see that it just stops inserting. No exception, it just stops inserting. Anyone got any idea what this may be? I've previously run the syncronization on another sql 2005 express (also on another computer), and that worked. The server has only 2GB RAM, could this be the problem?

  • C# WCF - Failed to invoke the service.

    - by Keith Barrows
    I am getting the following error when trying to use the WCF Test Client to hit my new web service. What is weird is every once in awhile it will execute once then start popping this error. Failed to invoke the service. Possible causes: The service is offline or inaccessible; the client-side configuration does not match the proxy; the existing proxy is invalid. Refer to the stack trace for more detail. You can try to recover by starting a new proxy, restoring to default configuration, or refreshing the service.

  • Installshield Development Error durring the Installation process

    - by Alopekos
    Hey guys, I've been stuck by a problem for the past couple days that makes no sense to me. My installer builds fine in the Installshiled IDE but when it is about to finish the installation, int gets two errors then rollbacks: installation failure. Right when the install bar is at about 100%, an error box pops up that states this: "Error 1001.Exception occurred while initializing the installation: System.IO.FileLoadException: Attempt to load an unverifiable executable with fixups (IAT with more than 2 sections or a TLS section.) (Exception from HRESULT: 0x80131019)." The box pops up once, then the installer flashes its status to "rollback" then pops up another error box, then once 'ok'ed it procedes to rollback as usual. I don't understand that error message so i looked in the msi loggings and found this: "InstallShield 13:20:08: Initializing Property Bag...

The installers that I've tried(and failed) have always needed to be Setup.exes, when i try to build a .msi only setup I get this error message. It may help someone who knows more about this system than I do. Your project contains InstallShield prerequisites. A Setup.exe setup launcher is required if you are build a release that includes InstallShield prerequisites. Change your release settings to build Setup.exe, or remove the prerequisites from your project. -7076 There's nothing on the site that has anything from the error code, so I'm at a loss. Thanks for any help possible, I'm an intern and I'm fresh out of ideas... Josh System: XP SP3 Installshield 2010 Pro Install being tested on a VirtualPC

  • Synapse and string problems with HTTPSend in Delphi 2010

    - by Mick
    I have been trying to get to the bottom of this problem off and on for the past 2 days and I'm really stuck. Hopefully some smart folks can help me out. The issue is that I have a function that I call in a thread that downloads a file (using Synapse libraries) from a website that is passed to it. However, I've found that every once in a while there are sites where it will not pull down a file, but wget or Firefox/IE will download it without issue. Digging into it, I've found some curious things. Here is the relevant code: uses //[..] HTTPSend, blcksock; //[..] type TMyThread = class(TThread) protected procedure Execute; override; private { Private declarations } fTheUrl: string; procedure GetFile(const TheUrl: string); public property thrd_TheUrl: string read fTheUrl write fTheUrl; end; implementation [..] procedure TMyThread.GetFile(const TheUrl: string); var HTTP: THTTPSend; success: boolean; sLocalUrl: string; IsSame : boolean; begin HTTP := THTTPSend.Create; try HTTP.UserAgent := 'Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 2.0.50727)'; HTTP.ProxyHost := 'MYPROXY.COM'; HTTP.ProxyPort := '80'; sLocalUrl := 'http://web.archive.org/web/20071212205017/energizer.com/usbcharger/download/UsbCharger_setup_V1_1_1.exe'; IsSame := SameText(sLocalUrl, sTheUrl); //this equals True when I debug /// /// /// THIS IS WHERE THE ISSUE BEGINS /// I will comment out 1 of the following when debugging /// HTTP.HTTPMethod('GET', sLocalUrl); // ----this works and WILL download the file HTTP.HTTPMethod('GET', sTheUrl); // --- this always fails, and HTTP.ResultString contains "Not Found" success := SysUtils.UpperCase(HTTP.ResultString) = 'OK'; if HTTP.ResultCode > 0 then success := True; //this is here just to keep the value around while debugging finally HTTP.Free; end; end; procedure TMyThread.Execute begin //fTheURL contains this value: http://web.archive.org/web/20071212205017/energizer.com/usbcharger/download/UsbCharger_setup_V1_1_1.exe GetFile(fTheUrl); end; The problem is that when I assign a local variable to the function and give it the URL directly, everything works. However, when passing the variable into the function, it fails. Anyone have any ideas? HTTP.HTTPMethod('GET', sLocalUrl); // ----this works and WILL download the file HTTP.HTTPMethod('GET', sTheUrl); // --- this always fails, and HTTP.ResultString contains "Not Found" I'm using the latest version of Synapse from their SVN repository (version from 2 days ago). NOTE: The file I am attempting to download is known to have a virus, the program I am writing is meant to download malicious files for analysis. So, don't execute the file once you download it. However, I'm using this URL b/c this is the one I can reproduce the issue with.

  • OpenGL/SharpGL - Points only on -near surface of Ortho projection?

    - by FTLPhysicsGuy
    When you create points using three dimensions for each point and you use an Ortho projection to view the points, would there be a reason that only the points on the -near surface would appear? For example, if you use (the SharpGL method) gl.Ortho(0, width, height, 0, -10, 10), only the points at z=10 (because the near surface is at -10) actually show up. I'm currently using SharpGL - but I'm hoping the issue I'm having isn't with that particular implementation/library. EDIT: I'm adding the code below that demonstrates the issue. Note that this example requires SharpGL and is in fact a modification of a WPF sample project that comes with the current SharpGL source code (the original sample project is called TwoDSample). The project requires a MainWindow.xaml and a MainWindow.xaml.cs. Here's the xaml: <Window x:Class="TwoDSample.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525" xmlns:my="clr-namespace:SharpGL.WPF;assembly=SharpGL.WPF"> <Grid> <my:OpenGLControl Name="openGLControl1" OpenGLDraw="openGLControl1_OpenGLDraw" OpenGLInitialized="openGLControl1_OpenGLInitialized" Resized="openGLControl1_Resized"/> </Grid> </Window> Here is the code behind: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Windows; using System.Windows.Controls; using System.Windows.Data; using System.Windows.Documents; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Imaging; using System.Windows.Navigation; using System.Windows.Shapes; using SharpGL.Enumerations; namespace TwoDSample { /// <summary> /// Interaction logic for MainWindow.xaml /// </summary> public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); } // NOTE: I use this to restrict the openGLControl1_OpenGLDraw method to // drawing only once after m_drawCount is set to zero; int m_drawCount = 0; private void openGLControl1_OpenGLDraw(object sender, SharpGL.SceneGraph.OpenGLEventArgs args) { // NOTE: Only draw once after m_drawCount is set to zero if (m_drawCount < 1) { // Get the OpenGL instance. var gl = args.OpenGL; gl.Color(1f, 0f, 0f); gl.PointSize(2.0f); // Draw 10000 random points. gl.Begin(BeginMode.Points); Random random = new Random(); for (int i = 0; i < 10000; i++) { double x = 10 + 400 * random.NextDouble(); double y = 10 + 400 * random.NextDouble(); double z = (double)random.Next(-10, 0); // Color the point according to z value gl.Color(0f, 0f, 1f); // default to blue if (z == -10) gl.Color(1f, 0f, 0f); // Red for z = -10 else if (z == -1) gl.Color(0f, 1f, 0f); // Green for z = -1 gl.Vertex(x, y, z); } gl.End(); m_drawCount++; } } private void openGLControl1_OpenGLInitialized(object sender, SharpGL.SceneGraph.OpenGLEventArgs args) { } private void openGLControl1_Resized(object sender, SharpGL.SceneGraph.OpenGLEventArgs args) { // NOTE: force the draw routine to happen again when resize occurs m_drawCount = 0; // Get the OpenGL instance. var gl = args.OpenGL; // Create an orthographic projection. gl.MatrixMode(MatrixMode.Projection); gl.LoadIdentity(); // NOTE: Basically no matter what I do, the only points I see are those at // the "near" surface (with z = -zNear)--in this case, I only see green points gl.Ortho(0, openGLControl1.ActualWidth, openGLControl1.ActualHeight, 0, 1, 10); // Back to the modelview. gl.MatrixMode(MatrixMode.Modelview); } } }

  • Android Title bar leaving space in when application is resumed

    - by user466607
    I am using a Tab Host in my Android App. I have the Titlebar hidden. When I leave the App and resume to it, I have some strange behaviour. If I resume to a tab using a list activity with listView.setAdapter, the title bar is hidden and the space it takes up is consumed by the App. However, if I resume to any tab without the listView.setAdapter, the Titlebar is hidden, but space which was used by it is left behind. This is pushes my tabs (which are positioned at the bottom of the screen) off the screen. The space is once again consumed by my app if I then change to any other tab. I have tried to invalidate most of the obvious Views in my App without and success. Below is my tab_activity xml. many thanks <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TabHost xmlns:android="http://schemas.android.com/apk/res/android" android:id="@android:id/tabhost" android:layout_width="fill_parent" android:layout_height="fill_parent"> <LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <FrameLayout android:id="@android:id/tabcontent" android:layout_width="fill_parent" android:layout_height="0dip" android:layout_weight="1" /> <TabWidget android:id="@android:id/tabs" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="0" /> </LinearLayout> </TabHost> </LinearLayout> Here is the Manifest <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.tar.projectx" android:versionCode="1" android:versionName="1.0"> <uses-sdk android:minSdkVersion="8" /> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> <uses-permission android:name="android.permission.CALL_PHONE" /> <uses-permission android:name="android.permission.READ_PHONE_STATE" /> <uses-permission android:name="android.permission.GET_ACCOUNTS" /> <uses-permission android:name="android.permission.READ_CONTACTS" /> <uses-permission android:name="android.permission.WRITE_CONTACTS" /> <application android:theme="@android:style/Theme.Light.NoTitleBar.Fullscreen" android:icon="@drawable/icon" android:label="@string/app_name" android:debuggable="true"> <activity android:name=".Splash" android:theme="@android:style/Theme.Light.NoTitleBar.Fullscreen" android:label="@string/app_name" android:screenOrientation="portrait"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name="SearchActivity" android:label="SearchActivity" android:screenOrientation="portrait"></activity> <activity android:name="SearchListActivity" android:label="SearchListActivity" android:screenOrientation="portrait"></activity> <activity android:name="ContactActivity" android:label="ContactActivity" android:screenOrientation="portrait"></activity> </application> </manifest> Interestingly, if I use the code below in the onResume method of my mainActivity which holds the tabhost, once the toast disappears, the view is refreshed and the space at the top is taken up by my app again. Obviously, this isn't much of a fix, but may help someone understand what is happening. @Override protected void onResume() { super.onResume(); Toast.makeText(this, "Welcome Back", Toast.LENGTH_LONG).show(); }

  • How to fix notifyDataSetChanged/ListView problems in dynamic Adapter wrapper Android

    - by ipaterson
    Summary: Trying to dynamically add heading rows to a ListView via a custom adapter wrapper. ListView is having trouble keeping the scroll position in sync. Runnable demo project provided. I would like to dynamically add items to a list based on the values in a CursorAdapter, several positions ahead of what the user is currently viewing. To do this, I have an adapter that wraps the CursorAdapter and keeps the new content indexed in a SparseArray. The ListView needs to be updated when items are added to the custom adapter, but I have met a lot of pitfalls trying to get that to work and would love some advice. The demo project can be downloaded here: http://dl.dropbox.com/u/15334423/DynamicSectionedList.zip In the demo, the headings are added dynamically by looking ahead 10 places to find the correct position where the list items switch to the next letter. Each implementation of notifyDataSetChanged has problems as described: Demo 1 This demo shows the importance of notifyDataSetChanged(). On clicking anything, the app will crash. This is due to some sanity checking in ListView... mItemCount != adapter.getItemCount(). Moral is, we need to notify the list that data has changed. Demo 2 The natural next step is to notify the ListView of changes when changes occur. Unfortunately, doing so while the ListView is scrolling firmly breaks all touch interaction until the app switches out of touch mode. You will need to "fling scroll" far enough to generate new headings in order to notice this. Tapping the screen will not cause the scroll to stop, and once stopped none of the list items will be clickable. This is due to some if (!mDataChanged) { /* do very important stuff */ } code in AbsListView.onTouchEvent(). Demo 3 To fix this, Demo 3 introduces a pendingChanges flag and the custom Adapter gains a notifyDataSetChangedIfNeeded() which can be called by the ListView once it has entered a "safe" state for changes. The first point where changes must be notified is in ListView.layoutChildren(), so I overrode that method to first notify of changes if needed, then call through. Fling past at least one heading then click a list item. This doesn't quite work right, though I'm not totally sure why. Tapping or selecting an item with the keyboard/trackball causes the list to refresh without properly syncing the old position. It scrolls to the top of the list which is not acceptable. Demo 4 The scroll problem in Demo 3 can be conquered, at least in touch mode. By adding a call to notifyDataSetChangedIfNeeded() on touch down, the data change happens to take place at such a time that all touch interaction works as expected and the list position is properly synced. However, I can't find an analog for that when the device is not in touch mode, not to mention the fact that it definitely seems like a hack. The list almost always scrolls back to the top, I can't find out what causes it to occasionally maintain the correct position. Since Android is fighting me at each step of the way, I feel like there should be a better approach. Please try the demo, if any fixes can be applied to get it working that would be great! Many thanks to anyone who can look into this, hopefully if we can get the code working it will be useful for others trying to accomplish the same optimization for lists with headings.

  • Jquery removeClass Not Working

    - by Wade D Ouellet
    Hey, My site is here: http://treethink.com What I have going is a news ticker on the right that is inside a jquery function. The function starts right away and extracts the news ticker and then retracts it as it should. When a navigation it adds a class to the div, which the function then checks for to see if it should stop extracting/retracting. This all works great. The problem I am having is that after the close button is clicked (in the content window), the removeClass won't work. This means that it keeps thinking the window is open and therefore the conditional statement inside the function won't let it extract and retract again. With a simple firebug check, it's showing that the class isn't being removed period. It's not the cboxClose id that it's not finding because I tried changing that to just "a" tags in general and it still wouldn't work so it's something to do with the jQuery for sure. Someone also suggested a quick alert() to check if the callback is working but I'm not sure what this is. Here is the code: /* News Ticker */ /* Initially hide all news items */ $('#ticker1').hide(); $('#ticker2').hide(); $('#ticker3').hide(); var randomNum = Math.floor(Math.random()*3); /* Pick random number */ newsTicker(); function newsTicker() { if (!$("#ticker").hasClass("noTicker")) { $("#ticker").oneTime(2000,function(i) { /* Do the first pull out once */ $('div#ticker div:eq(' + randomNum + ')').show(); /* Select div with random number */ $("#ticker").animate({right: "0"}, {duration: 800 }); /* Pull out ticker with random div */ }); $("#ticker").oneTime(15000,function(i) { /* Do the first retract once */ $("#ticker").animate({right: "-450"}, {duration: 800}); /* Retract ticker */ $("#ticker").oneTime(1000,function(i) { /* Afterwards */ $('div#ticker div:eq(' + (randomNum) + ')').hide(); /* Hide that div */ }); }); $("#ticker").everyTime(16500,function(i) { /* Everytime timer gets to certain point */ /* Show next div */ randomNum = (randomNum+1)%3; $('div#ticker div:eq(' + (randomNum) + ')').show(); $("#ticker").animate({right: "0"}, {duration: 800}); /* Pull out right away */ $("#ticker").oneTime(15000,function(i) { /* Afterwards */ $("#ticker").animate({right: "-450"}, {duration: 800});/* Retract ticker */ }); $("#ticker").oneTime(16000,function(i) { /* Afterwards */ /* Hide all divs */ $('#ticker1').hide(); $('#ticker2').hide(); $('#ticker3').hide(); }); }); } else { $("#ticker").animate({right: "-450"}, {duration: 800}); /* Retract ticker */ $("#ticker").oneTime(1000,function(i) { /* Afterwards */ $('div#ticker div:eq(' + (randomNum) + ')').hide(); /* Hide that div */ }); $("#ticker").stopTime(); } } /* when nav item is clicked re-run news ticker function but give it new class to prevent activity */ $("#nav li").click(function() { $("#ticker").addClass("noTicker"); newsTicker(); }); /* when close button is clicked re-run news ticker function but take away new class so activity can start again */ $("#cboxClose").click(function() { $("#ticker").removeClass("noTicker"); newsTicker(); }); Thanks, Wade

  • ASP.NET MVC 2 "value" in DataAnnotation attribute passed is null, when incorrect date is submitted.

    - by goldenelf2
    Hello to all! This is my first question here on stack overflow. i need help on a problem i encountered during an ASP.NET MVC2 project i am currently working on. I should note that I'm relatively new to MVC design, so pls bear my ignorance. Here goes : I have a regular form on which various details about a person are shown. One of them is "Date of Birth". My view is like this <div class="form-items"> <%: Html.Label("DateOfBirth", "Date of Birth:") %> <%: Html.EditorFor(m => m.DateOfBirth) %> <%: Html.ValidationMessageFor(m => m.DateOfBirth) %> </div> I'm using an editor template i found, to show only the date correctly : <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<System.DateTime?>"%> <%= Html.TextBox("", (Model.HasValue ? Model.Value.ToShortDateString() : string.Empty))%> I used LinqToSql designer to create my model from an sql database. In order to do some validation i made a partial class Person to extend the one created by the designer (under the same namespace) : [MetadataType(typeof(IPerson))] public partial class Person : IPerson { //To create buddy class } public interface IPerson { [Required(ErrorMessage="Please enter a name")] string Name { get; set; } [Required(ErrorMessage="Please enter a surname")] string Surname { get; set; } [Birthday] DateTime? DateOfBirth { get; set; } [Email(ErrorMessage="Please enter a valid email")] string Email { get; set; } } I want to make sure that a correct date is entered. So i created a custom DataAnnotation attribute in order to validate the date : public class BirthdayAttribute : ValidationAttribute { private const string _errorMessage = "Please enter a valid date"; public BirthdayAttribute() : base(_errorMessage) { } public override bool IsValid(object value) { if (value == null) { return true; } DateTime temp; bool result = DateTime.TryParse(value.ToString(), out temp); return result; } } Well, my problem is this. Once i enter an incorrect date in the DateOfBirth field then no custom message is displayed even if use the attribute like [Birthday(ErrorMessage=".....")]. The message displayed is the one returned from the db ie "The value '32/4/1967' is not valid for DateOfBirth.". I tried to enter some break points around the code, and found out that the "value" in attribute is always null when the date is incorrect, but always gets a value if the date is in correct format. The same ( value == null) is passed also in the code generated by the designer. This thing is driving me nuts. Please can anyone help me deal with this? Also if someone can tell me where exactly is the point of entry from the view to the database. Is it related to the model binder? because i wanted to check exactly what value is passed once i press the "submit" button. Thank you.

  • Problem receving in RXTX

    - by drhorrible
    I've been using RXTX for about a year now, without too many problems. I just started a new program to interact with a new piece of hardware, so I reused the connect() method I've used on my other projects, but I have a weird problem I've never seen before. The Problem The device works fine, because when I connect with hyperterminal, I send things and receive what I expect, and Serial Port Monitor(SPM) reflects this. However, when I run the simple hyperterminal-clone I wrote to diagnose the problem I'm having with my main app, bytes are sent, according to SPM, but nothing is received, and my SerialPortEventListener never fires. Even when I check for available data in the main loop, reader.ready() returns false. If I ignore this check, then I get an exception, details below. Relevant section of connect() method // Configure and open port port = (SerialPort) CommPortIdentifier.getPortIdentifier(name) .open(owner,1000) port.setSerialPortParams(baud, databits, stopbits, parity); port.setFlowControlMode(fc_mode); final BufferedReader br = new BufferedReader( new InputStreamReader( port.getInputStream(), "US-ASCII")); // Add listener to print received characters to screen port.addEventListener(new SerialPortEventListener(){ public void serialEvent(SerialPortEvent ev) { try { System.out.println("Received: "+br.readLine()); } catch (IOException e) { e.printStackTrace(); } } }); port.notifyOnDataAvailable(); Exception java.io.IOException: Underlying input stream returned zero bytes at sun.nio.cs.StreamDecoder.readBytes(StreamDecoder.java:268) at sun.nio.cs.StreamDecoder.implRead(StreamDecoder.java:306) at sun.nio.cs.StreamDecoder.read(StreamDecoder.java:158) at java.io.InputStreamReader.read(InputStreamReader.java:167) at java.io.BufferedReader.fill(BufferedReader.java:136) at java.io.BufferedReader.read(BufferedReader.java:157) at <my code> The big question (again) I think I've eliminated all possible hardware problems, so what could be wrong with my code, or the RXTX library? Edit: something interesting When I open hyperterminal after sending a bunch of commands from java that should have gotten responses, all of the responses appear immediately, as if they had been put in the buffer somewhere, but unavailable. Edit 2: Tried something new, same results I ran the code example found here, with the same results. No data came in, but when I switched to a new program, it came all at once. Edit 3 The hardware is fine, and even a different computer has the same problem. I am not using any sort of USB adapter. I've started using PortMon, too, and it's giving me some interesting results. Hyperterminal and RXTX are not using the same settings, and RXTX always polls the port, unlike HyperTerminal, but I still can't see what settings would affect this. As soon as I can isolate the configuration from the constant polling, I'll post my PortMon logs. Edit 4 Is it possible that some sort of Windows update in the last 3 months could have caused this? It has screwed up one of my MATLAB mex-based programs once. Edit 5 I've also noticed some things that are different between HyperTerminal, RXTX, and a separate program I found that communicates with the device (but doesn't do what I want, which is why I'm rolling my own program) HyperTerminal - set to no flow control, but Serial Port Monitor's RTS and DTR indicators are green Other program - not sure what settings it thinks it's using, but only SPM's RTS indicator is green RXTX - no matter what flow control I set, only SPM's CTS and DTR indicators are on. From Serial Port Monitor's help files (paraphrased): the indicators display the state of the serial control lines RTS - Request To Send CTS - Clear To Send DTR - Data Terminal Ready

  • Resons why I'm using php rather then asp.net [closed]

    - by spirytus
    I have basic idea of how asp .Net works, but finds all framework hard to use if you are a newbie. I found compiling, web applications vs websites and all that stuff you should know to program in asp .net a bit tedious and so personally I go with php to create small, to medium applications for my clients. There are couple of reasons for it: php is easy scripting language, top to bottom and you done. You still can create objects, classes and if you have idea of MVC its fairly easy to create basic structure yourself so you can keep you presentation layer "relatively" clean. Although I find myself still mixing basic logic in my view's, I am trying to stick to booleans, and for each loops. ASP .net keeps it cleaner as far as I know and I agree that this is great. Heaps of free stuff for php and lots of help everywhere Although choice of IDE's for php is very limited, I still don't have to be stuck with VisualStudio. Lets be honest.. you can program in whatever you like but does anyone uses anything else other than VS? For basic applications I create, Visual Studio doesn't come even close to notepad :) / phpEdit (or similar) combination. It lacks of many features I constantly use, although armies of developers are using it and it must be for good reason. Personally not a big fan of VS though. Being on the market for that long should make editing much easier. I know .Net comes with awesome set of controls, validators etc. which is truly awesome. For me the problem starts if I want my validator to behave slightly different way and lets say fade in/out error messages. I know its possible to extend it behavior, plug into lifecycle and output different JS to the client and so on. I just never see it happen in places I work, and honestly, I don't even think most of .net developers I worked with during last couple of years would know how to do that. In php I have to grab some plugin for jQuery and use it for validation, which is fairly easy task once you had done it before. Again I'm sure its easy for .net gurus, but for newbie like me its almost impossible. I found that many asp .net programmers are very limited in what they are able to do and basically whack together .net applications using same lame set of controls, not even bothering in looking into how it works and what if? Now I don't want to anger anyone :) I know there is huge number of excellent .Net developers who know their stuff and are able to extend controls and do all that magic in no time. I found it a bit annoying though that many of them stick to what is provided without even trying to make it better. Nothing against .net here, just a thought really :) I remember when asp.net came out the idea was that front-end people will not be able to screw anything up and do their fron-end stuff without worrying what happens behind. Now its never that easy and I always tend to get server side people to fix this and that during development. Things like ID's assigned to controls can very easily make your application break and if someone is pure HTML guy using VS its easy to break something. Thats my thoughs on php and .net and reasons why for my work I go with php. I know that once learned asp .net is awesome technology and summing all up php doesn't even come close to it. For someone like me however, individually developing small basic applications for clients, php seems to work much better. Please let me know your thoughts on the above :)

  • WiX Action Sequence

    - by Damian Vogel
    I was looking for list of actions and their sequence when running a WiX setup. Somehow the official website doesn't seem to provide any information. The basic problem is that I want to schedule my custom actions correctly. Typically I need to register a DLL with regsvr32.exe, and this can only be done once the files are copied to the harddrive. However the custom action <Custom Action="RegisterShellExt" After="InstallFiles"> failed with the error message "file not found". What I've done then is analizing the log of my MSI with WiX Edit, and I've found that the Action InstallFiles exists more than once. And effectively the files are written only the second time it appears. So I changed my custom action to the following : <Custom Action="RegisterShellExt" Before="InstallFinalize"> Here is the sequence I've extracted from the logs of my MSI: Action start 15:16:49: INSTALL. Action start 15:16:49: PrepareDlg. Action start 15:16:49: AppSearch. Action start 15:16:49: LaunchConditions. Action start 15:16:49: ValidateProductID.

  • RSA Encrypt / Decrypt Problem in .NET

    - by Brendon Randall
    I'm having a problem with C# encrypting and decrypting using RSA. I have developed a web service that will be sent sensitive financial information and transactions. What I would like to be able to do is on the client side, Encrypt the certain fields using the clients RSA Private key, once it has reached my service it will decrypt with the clients public key. At the moment I keep getting a "The data to be decrypted exceeds the maximum for this modulus of 128 bytes." exception. I have not dealt much with C# RSA cryptography so any help would be greatly appreciated. This is the method i am using to generate the keys private void buttonGenerate_Click(object sender, EventArgs e) { string secretKey = RandomString(12, true); CspParameters param = new CspParameters(); param.Flags = CspProviderFlags.UseMachineKeyStore; SecureString secureString = new SecureString(); byte[] stringBytes = Encoding.ASCII.GetBytes(secretKey); for (int i = 0; i < stringBytes.Length; i++) { secureString.AppendChar((char)stringBytes[i]); } secureString.MakeReadOnly(); param.KeyPassword = secureString; RSACryptoServiceProvider rsaProvider = new RSACryptoServiceProvider(param); rsaProvider = (RSACryptoServiceProvider)RSACryptoServiceProvider.Create(); rsaProvider.KeySize = 1024; string publicKey = rsaProvider.ToXmlString(false); string privateKey = rsaProvider.ToXmlString(true); Repository.RSA_XML_PRIVATE_KEY = privateKey; Repository.RSA_XML_PUBLIC_KEY = publicKey; textBoxRsaPrivate.Text = Repository.RSA_XML_PRIVATE_KEY; textBoxRsaPublic.Text = Repository.RSA_XML_PUBLIC_KEY; MessageBox.Show("Please note, when generating keys you must sign on to the gateway\n" + " to exhange keys otherwise transactions will fail", "Key Exchange", MessageBoxButtons.OK, MessageBoxIcon.Information); } Once i have generated the keys, i send the public key to the web service which stores it as an XML file. Now i decided to test this so here is my method to encrypt a string public static string RsaEncrypt(string dataToEncrypt) { string rsaPrivate = RSA_XML_PRIVATE_KEY; CspParameters csp = new CspParameters(); csp.Flags = CspProviderFlags.UseMachineKeyStore; RSACryptoServiceProvider provider = new RSACryptoServiceProvider(csp); provider.FromXmlString(rsaPrivate); ASCIIEncoding enc = new ASCIIEncoding(); int numOfChars = enc.GetByteCount(dataToEncrypt); byte[] tempArray = enc.GetBytes(dataToEncrypt); byte[] result = provider.Encrypt(tempArray, true); string resultString = Convert.ToBase64String(result); Console.WriteLine("Encrypted : " + resultString); return resultString; } I do get what seems to be an encrypted value. In the test crypto web method that i created, i then take this encrypted data, try and decrypt the data using the clients public key and send this back in the clear. But this is where the exception is thrown. Here is my method responsible for this. public string DecryptRSA(string data, string merchantId) { string clearData = null; try { CspParameters param = new CspParameters(); param.Flags = CspProviderFlags.UseMachineKeyStore; RSACryptoServiceProvider rsaProvider = new RSACryptoServiceProvider(param); string merchantRsaPublic = GetXmlRsaKey(merchantId); rsaProvider.FromXmlString(merchantRsaPublic); byte[] asciiString = Encoding.ASCII.GetBytes(data); byte[] decryptedData = rsaProvider.Decrypt(asciiString, false); clearData = Convert.ToString(decryptedData); } catch (CryptographicException ex) { Log.Error("A cryptographic error occured trying to decrypt a value for " + merchantId, ex); } return clearData; } If anyone could help me that would be awesome, as i have said i have not done much with C# RSA encryption/decryption.

  • Problems with Android Fragment back stack

    - by DexterMoon
    I've got a massive problem with the way the android fragment backstack seems to work and would be most grateful for any help that is offered. Imagine you have 3 Fragments [1] [2] [3] I want the user to be able to navigate [1] > [2] > [3] but on the way back (pressing back button) [3] > [1]. As I would have imagined this would be accomplished by not calling addToBackStack(..) when creating the transaction that brings fragment [2] into the fragment holder defined in XML. The reality of this seems as though that if I dont want [2] to appear again when user presses back button on [3], I must not call addToBackStack in the transaction that shows fragment [3]. This seems completely counter-intuitive (perhaps coming from the iOS world). Anyway if i do it this way, when I go from [1] > [2] and press back I arrive back at [1] as expected. If I go [1] > [2] > [3] and then press back I jump back to [1] (as expected). Now the strange behavior happens when I try and jump to [2] again from [1]. First of all [3] is briefly displayed before [2] comes into view. If I press back at this point [3] is displayed, and if I press back once again the app exits. Can anyone help me to understand whats going on here? And here is the layout xml file for my main activity: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <fragment android:id="@+id/headerFragment" android:layout_width="match_parent" android:layout_height="wrap_content" class="com.fragment_test.FragmentControls" > <!-- Preview: layout=@layout/details --> </fragment> <FrameLayout android:id="@+id/detailFragment" android:layout_width="match_parent" android:layout_height="fill_parent" /> Update This is the code I'm using to build by nav heirarchy Fragment frag; FragmentTransaction transaction; //Create The first fragment [1], add it to the view, BUT Dont add the transaction to the backstack frag = new Fragment1(); transaction = getSupportFragmentManager().beginTransaction(); transaction.replace(R.id.detailFragment, frag); transaction.commit(); //Create the second [2] fragment, add it to the view and add the transaction that replaces the first fragment to the backstack frag = new Fragment2(); transaction = getSupportFragmentManager().beginTransaction(); transaction.replace(R.id.detailFragment, frag); transaction.addToBackStack(null); transaction.commit(); //Create third fragment frag = new Fragment3(); transaction = getSupportFragmentManager().beginTransaction(); transaction.replace(R.id.detailFragment, frag); transaction.commit(); //END OF SETUP CODE------------------------- //NOW: //Press back once and then issue the following code: frag = new Fragment2(); transaction = getSupportFragmentManager().beginTransaction(); transaction.replace(R.id.detailFragment, frag); transaction.addToBackStack(null); transaction.commit(); //Now press back again and you end up at fragment [3] not [1] Many thanks

  • Trouble calculating correct decimal digits.

    - by Crath
    I am trying to create a program that will do some simple calculations, but am having trouble with the program not doing the correct math, or placing the decimal correctly, or something. Some other people I asked cannot figure it out either. Here is the code: http://pastie.org/887352 When you enter the following data: Weekly Wage: 500 Raise: 3 Years Employed: 8 It outputs the following data: Year Annual Salary 1 $26000.00 2 $26780.00 3 $27560.00 4 $28340.00 5 $29120.00 6 $29900.00 7 $30680.00 8 $31460.00 And it should be outputting: Year Annual Salary 1 $26000.00 2 $26780.00 3 $27583.40 4 $28410.90 5 $29263.23 6 $30141.13 7 $31045.36 8 $31976.72 Here is the full description of the task: 8.17 ( Pay Raise Calculator Application) Develop an application that computes the amount of money an employee makes each year over a user- specified number of years. Assume the employee receives a pay raise once every year. The user specifies in the application the initial weekly salary, the amount of the raise (in percent per year) and the number of years for which the amounts earned will be calculated. The application should run as shown in Fig. 8.22. in your text. (fig 8.22 is the output i posted above as what my program should be posting) Opening the template source code file. Open the PayRaise.cpp file in your text editor or IDE. Defining variables and prompting the user for input. To store the raise percentage and years of employment that the user inputs, define int variables rate and years, in main after line 12. Also define double variable wage to store the user’s annual wage. Then, insert statements that prompt the user for the raise percentage, years of employment and starting weekly wage. Store the values typed at the keyboard in the rate, years and wage variables, respectively. To find the annual wage, multiply the new wage by 52 (the number of weeks per year) and store the result in wage. Displaying a table header and formatting output. Use the left and setw stream manipulators to display a table header as shown in Fig. 8.22 in your text. The first column should be six characters wide. Then use the fixed and setprecision stream manipulators to format floating- point values with two positions to the left of the decimal point. Writing a for statement header. Insert a for statement. Before the first semicolon in the for statement header, define and initialize the variable counter to 1. Before the second semicolon, enter a loop- continuation condition that will cause the for statement to loop until counter has reached the number of years entered. After the second semicolon, enter the increment of counter so that the for statement executes once for each number of years. Calculating the pay raise. In the body of the for statement, display the value of counter in the first column and the value of wage in the second column. Then calculate the new weekly wage for the following year, and store the resulting value in the wage variable. To do this, add 1 to the percentage increase (be sure to divide the percentage by 100.0 ) and multiply the result by the current value in wage. Save, compile and run the application. Input a raise percentage and a number of years for the wage increase. View the results to ensure that the correct years are displayed and that the future wage results are correct. Close the Command Prompt window. We can not figure it out! Any help would be greatly appreciated, thanks!

  • Any tool to make git build every commit to a branch in a seperate repository?

    - by Wayne
    A git tool that meets the specs below is needed. Does one already exists? If not, I will create a script and make it available on GitHub for others to use or contribute. Is there a completely different and better way to solve the need to build/test every commit to a branch in a git repository? Not just to the latest but each one back to a certain staring point. Background: Our development environment uses a separate continuous integration server which is wonderful. However, it is still necessary to do full builds locally on each developer's PC to make sure the commit won't "break the build" when pushed to the CI server. Unfortunately, with auto unit tests, those build force the developer to wait 10 or 15 minutes for a build every time. To solve this we have setup a "mirror" git repository on each developer PC. So we develop in the main repository but anytime a local full build is needed. We run a couple commands in a in the mirror repository to fetch, checkout the commit we want to build, and build. It's works extremely lovely so we can continue working in the main one with the build going in parallel. There's only one main concern now. We want to make sure every single commit builds and tests fine. But we often get busy and neglect to build several fresh commits. Then if it the build fails you have to do a bisect or manually figure build each interim commit to figure out which one broke. Requirements for this tool. The tool will look at another repo, origin by default, fetch and compare all commits that are in branches to 2 lists of commits. One list must hold successfully built commits and the other lists commits that failed. It identifies any commit or commits not yet in either list and begins to build them in a loop in the order that they were committed. It stops on the first one that fails. The tool appropriately adds each commit to either the successful or failed list after it as attempted to build each one. The tool will ignore any "legacy" commits which are prior to the oldest commit in the success list. This logic makes the starting point possible in the next point. Starting Point. The tool building a specific commit so that, if successful it gets added to the success list. If it is the earliest commit in the success list, it becomes the "starting point" so that none of the commits prior to that are examined for builds. Only linear tree support? Much like bisect, this tool works best on a commit tree which is, at least from it's starting point, linear without any merges. That is, it should be a tree which was built and updated entirely via rebase and fast forward commits. If it fails on one commit in a branch it will stop without building the rest that followed after that one. Instead if will just move on to another branch, if any. The tool must do these steps once by default but allow a parameter to loop with an option to set how many seconds between loops. Other tools like Hudson or CruiseControl could do more fancy scheduling options. The tool must have good defaults but allow optional control. Which repo? origin by default. Which branches? all of them by default. What tool? by default an executable file to be provided by the user named "buildtest", "buildtest.sh" "buildtest.cmd", or buildtest.exe" in the root folder of the repository. Loop delay? run once by default with option to loop after a number of seconds between iterations.

  • How do I center a UIImageView within a full-screen UIScrollView?

    - by Sebastian Celis
    In my application, I would like to present the user with a full-screen photo viewer much like the one used in the Photos app. This is just for a single photo and as such should be quite simple. I just want the user to be able to view this one photo with the ability to zoom and pan. I have most of it working. And, if I do not center my UIImageView, everything behaves perfectly. However, I really want the UIImageView to be centered on the screen when the image is sufficiently zoomed out. I do not want it stuck to the top-left corner of the scroll view. Once I attempt to center this view, my vertical scrollable area appears to be greater than it should be. As such, once I zoom in a little, I am able to scroll about 100 pixels past the top of the image. What am I doing wrong? @interface MyPhotoViewController : UIViewController <UIScrollViewDelegate> { UIImage* photo; UIImageView *imageView; } - (id)initWithPhoto:(UIImage *)aPhoto; @end @implementation MyPhotoViewController - (id)initWithPhoto:(UIImage *)aPhoto { if (self = [super init]) { photo = [aPhoto retain]; // Some 3.0 SDK code here to ensure this view has a full-screen // layout. } return self; } - (void)dealloc { [photo release]; [imageView release]; [super dealloc]; } - (void)loadView { // Set the main view of this UIViewController to be a UIScrollView.

  • Django ImageField issue with JPEG's

    - by Kieran Lynn
    I am having a major issue with PIL (Python Image Library) in Django and have jumpped through a lot of hoops and have thus far not been able to figure out what the root of the issue is. The problem essentially breaks down to not being able to upload JPEG images through the ImageField in the Django admin. But the issue is not as simple as installing libjpeg. First, I installed PIL (through Buildout) and realized once it was installed that I had not installed libjpeg because JPEG support was not available. Having not setup the server myself, I just assumed that it was not installed and I compiled libjpeg 8 from the source. This ended up in my /usr/local/lib/ directory. I cleared out my Buildout files and rebuilt everything. This time when PIL compiled I had JPEG support. But I went to the Django Admin and tried to upload a JPEG though an ImageField with no luck. I got the "Upload a valid image. The file you uploaded was either not an image or a corrupted image" error. Just as a test I opened up a the Djano shell and ran the following: > import Image > i = Image.open( "/absolute_path/file.jpg" ) > print i <JpegImagePlugin.JpegImageFile image mode=RGB size=940x375 at 0x7F908C529BD8> This runs with no errors and shows that PIL is able to open JPEG's. After doing some reading, I come across this thread: Is it possible to control which libraries apache uses? Looks like PHP also uses libjpeg and is loading before Django, and therefor loading libjpeg 6.2 before. This is show when using lsof: COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME apache2 2561 www-data mem REG 202,1 146032 639276 /usr/lib/libjpeg.so.62.0.0 So my thought is that I should be using libjpeg 6.2. So I removed libjpeg located in my /usr/local/lib directory. After rereading the PIL installation instructions, I realized that I might not have the dev/header files for libjpeg that PIL needs. So I also uninstalled libjpeg using the aptitude uninstaller (sudo aptitude remove libjpeg62). Then to ensure that I got the header files that PIL needed I installed libjpeg using aptitude: (sudo aptget install libjpeg62-dev). From here I cleaned out my Buildout directory, and reran Buildout, which in turn reinstalled PIL. Once again, I have JPEG support, now using the libjpeg62. So I go to test in the Django Admin. Still no JPEG support. So I wanted to test JPEG support in general and see if the exception was not handled, what kind of error it would throw. So in my homepage view I added the following code to open a JPEG image: import Image i = Image.open( "/absolute_path/file.jpg" ) v = i.verify() Then I pass i to the HTML view just to easily see the output. I deploy these changes to the server and restart. I am surprised not to see an error and get the following output: {{ i }} - <JpegImagePlugin.JpegImageFile image mode=RGB size=940x375 at 0x7F908C529BD8> {{ v }} - None So at this point I am really confused: Why can I successfully open a JPEG while the admin cannot? Am I missing something, is this not an issue with libjpeg? If not an issue with libjpeg, why can I upload a PNG with no issues? Any help would be much appreciated, I have been on this for 2 days debugging with no luck. Setup: 1. Rackspace Cloud Server 2. Ubuntu 10.04 3. Django 1.2.3 (Installed though Buildout) 4. PIL 1.1.7 (Installed though Buildout) 5. libjpeg 6.2 (installed through aptitude (sudo aptget install libjpeg62-dev)

  • Why do UInt16 arrays seem to add faster than int arrays?

    - by scraimer
    It seems that C# is faster at adding two arrays of UInt16[] than it is at adding two arrays of int[]. This makes no sense to me, since I would have assumed the arrays would be word-aligned, and thus int[] would require less work from the CPU, no? I ran the test-code below, and got the following results: Int for 1000 took 9896625613 tick (4227 msec) UInt16 for 1000 took 6297688551 tick (2689 msec) The test code does the following: Creates two arrays named a and b, once. Fills them with random data, once. Starts a stopwatch. Adds a and b, item-by-item. This is done 1000 times. Stops the stopwatch. Reports how long it took. This is done for int[] a, b and for UInt16 a,b. And every time I run the code, the tests for the UInt16 arrays take 30%-50% less time than the int arrays. Can you explain this to me? Here's the code, if you want to try if for yourself: public static UInt16[] GenerateRandomDataUInt16(int length) { UInt16[] noise = new UInt16[length]; Random random = new Random((int)DateTime.Now.Ticks); for (int i = 0; i < length; ++i) { noise[i] = (UInt16)random.Next(); } return noise; } public static int[] GenerateRandomDataInt(int length) { int[] noise = new int[length]; Random random = new Random((int)DateTime.Now.Ticks); for (int i = 0; i < length; ++i) { noise[i] = (int)random.Next(); } return noise; } public static int[] AddInt(int[] a, int[] b) { int len = a.Length; int[] result = new int[len]; for (int i = 0; i < len; ++i) { result[i] = (int)(a[i] + b[i]); } return result; } public static UInt16[] AddUInt16(UInt16[] a, UInt16[] b) { int len = a.Length; UInt16[] result = new UInt16[len]; for (int i = 0; i < len; ++i) { result[i] = (ushort)(a[i] + b[i]); } return result; } public static void Main() { int count = 1000; int len = 128 * 6000; int[] aInt = GenerateRandomDataInt(len); int[] bInt = GenerateRandomDataInt(len); Stopwatch s = new Stopwatch(); s.Start(); for (int i=0; i<count; ++i) { int[] resultInt = AddInt(aInt, bInt); } s.Stop(); Console.WriteLine("Int for " + count + " took " + s.ElapsedTicks + " tick (" + s.ElapsedMilliseconds + " msec)"); UInt16[] aUInt16 = GenerateRandomDataUInt16(len); UInt16[] bUInt16 = GenerateRandomDataUInt16(len); s = new Stopwatch(); s.Start(); for (int i=0; i<count; ++i) { UInt16[] resultUInt16 = AddUInt16(aUInt16, bUInt16); } s.Stop(); Console.WriteLine("UInt16 for " + count + " took " + s.ElapsedTicks + " tick (" + s.ElapsedMilliseconds + " msec)"); }

  • Event bubbling with img tags?

    - by Kenny Bones
    I did some googling and figured I'm probably experiencing so called "event bubbling" that I've never heard of but are not surprised by it's existance. I want it to fire only once and I'm wondering how to fix this. Basically, I have this small code snippet: $('.bggallery_images').click(function () { alert('test'); }); This is supposed to fire once from a php snippet that basically adds an image of each image from a specific folder. It then outputs an echo string where each image has the class of "bggallery_images". PHP snippet looks like this: <?php $dirname = "img"; $images = scandir($dirname); $ignore = Array(".", ".."); foreach($images as $file) { if(!in_array($file, $ignore)) { echo "<img class=\"bggallery_images\" src=\"$dirname/$file\" />"; }; } ?> This all generates the html markup that looks like this for each image: <img src="img/WhitePattern6.gif" class="bggallery_images"> What is happening here? Here's the rendered output from FireBug: <div id="gallery_lightbox" style="height: 215px; z-index: 4; display: block;"> <div id="close"></div> <h2><cufon class="cufon cufon-canvas" alt="Velg " style="width: 39px; height: 20px;"><canvas width="49" height="23" style="width: 49px; height: 23px; top: -4px; left: 0px;"></canvas><cufontext>Velg </cufontext></cufon><cufon class="cufon cufon-canvas" alt="bakgrunnsbilde" style="width: 123px; height: 20px;"><canvas width="129" height="23" style="width: 129px; height: 23px; top: -4px; left: 0px;"></canvas><cufontext>bakgrunnsbilde</cufontext></cufon></h2> <div class="bggallery_images">testererererer</div> <img src="img/Bakgrunner/4462-v4.jpg" class="bggallery_images"><img src="img/Bakgrunner/5922.gif" class="bggallery_images"><img src="img/Bakgrunner/BluePattern.gif" class="bggallery_images"><img src="img/Bakgrunner/Brown1.gif" class="bggallery_images"><img src="img/Bakgrunner/Brown2Pattern.jpg" class="bggallery_images"><img src="img/Bakgrunner/BrownPattern.jpg" class="bggallery_images"><img src="img/Bakgrunner/Brownn.gif" class="bggallery_images"><img src="img/Bakgrunner/GrayPattern.gif" class="bggallery_images"><img src="img/Bakgrunner/GreenPattern3.gif" class="bggallery_images"><img src="img/Bakgrunner/OrangePattern.gif" class="bggallery_images"><img src="img/Bakgrunner/PurplePattern.gif" class="bggallery_images"><img src="img/Bakgrunner/PurplePattern2.gif" class="bggallery_images"><img src="img/Bakgrunner/RedPattern3.gif" class="bggallery_images"><img src="img/Bakgrunner/RedPattern4.gif" class="bggallery_images"><img src="img/Bakgrunner/RedPattern5.gif" class="bggallery_images"><img src="img/Bakgrunner/Tiled_Wallpaper__Green_Texture_by_knitetgantt.png" class="bggallery_images"><img src="img/Bakgrunner/WhitePattern4.gif" class="bggallery_images"><img src="img/Bakgrunner/WhitePattern5.gif" class="bggallery_images"><img src="img/Bakgrunner/WhitePattern6.gif" class="bggallery_images"><img src="img/Bakgrunner/WhitePattern7.gif" class="bggallery_images"><img src="img/Bakgrunner/WhitePurple.jpg" class="bggallery_images"><img src="img/Bakgrunner/YellowPattern.gif" class="bggallery_images"><img src="img/Bakgrunner/vintage-wallpaper.jpg" class="bggallery_images"> </div>
