  • using array_sum() in a while loop

    - by m477
    Hi folks, I'm learning PHP. Having trouble understanding why this piece of code isn't working. In particular: why is the result of array_sum($x) (1596) greater than $cap? Perhaps I'm not understanding the nature of while loops, but it seems to me (looking at a print_r($x)), the loop should cut out a step before it actually does. <?php function fibonacci_sum($cap = 1000){ list( $cur, $nxt, $seq ) = array( 0, 1, array() ); while ( array_sum($seq) < $cap ) { $seq[] = $cur; $add = $cur + $nxt; $cur = $nxt; $nxt = $add; } return $seq; } $x = fibonacci_sum(); echo array_sum($x); ?> Any insight is appreciated. Best, matt

  • Deploying a Rails App to Multiple Servers using Capistrano - Best Practices

    - by Louise
    I have a rails application that I need to deploy to 3 servers - machine1.com, machine2.com and machine3.com. I want to be able to deploy it to all machines at once and each machine individually. Can someone help me out with a skeleton Capistrano config file / recipe? Should it all be in deploy.rb or should I break it out in machine1.rb, etc? I thought I was on the right track getting Capistrano to take in command line arguments, but it choked when I tried set the roles within the namespaces. I'd pass in 'hosts=1,2,3' as an argument and set the role:app/web/db to "machine#{host}.com" after splitting on the command and going into an each do |host| {}... Anyway, other than creating 4 different deploy.rb files and renaming it before running cap:deploy each time, I'm stumped. I'd like to be able to do the following: cap deploy:machine1:latest_version_from_svn cap deploy:all_machines:latest:version_from_svn Just don't know if it should all be in deploy.rb split up with namespaces or if it should be broken into multiple deploy*.rb files.

  • OpenCv not initializing usb camera

    - by brainbarshan
    I am trying to capture video from usb camera using OpenCv. #include <highgui.h> #include <iostream> using namespace std; using namespace cv ; int main() { VideoCapture cap (-1); if(!cap.isOpened()) cout << "Cam initialize failed" ; else cout << "Cam initialized" ; return 0; } It is failing to initialize the camera. cap.isOpened() is returning zero. The same program, with same version of OpenCv and same usb camera, is correctly running in my friend's machine. I am running fedora 16. I did some searching in Google and Stack Overflow. But no useful help. Any idea ?

  • Windows Phone 7 ActiveSync error 86000C09 (My First Post!)

    - by Chris Heacock
    Hello fellow geeks! I'm kicking off this new blog with an issue that was a real nuisance, but was relatively easy to fix. During a recent Exchange 2003 to 2010 migration, one of the users was getting an error on his Windows Phone 7 device. The error code that popped up on the phone on every sync attempt was 86000C09 We tested the following: Different user on the same device: WORKED Problem user on a different device: FAILED   Seemed to point (conclusively) at the user's account as the crux of the issue. This error can come up if a user has too many devices syncing, but he had no other phones. We verified that using the following command: Get-ActiveSyncDeviceStatistics -Identity USERID Turns out, it was the old familiar inheritable permissions issue in Active Directory. :-/ This user was not an admin, nor had he ever been one. HOWEVER, his account was cloned from an ex-admin user, so the unchecked box stayed unchecked. We checked the box and voila, data started flowing to his device(s). Here's a refresher on enabling Inheritable permissions: Open ADUC, and enable Advanced Features: Then open properties and go to the Security tab for the user in question: Click on Advanced, and the following screen should pop up: Verify that "Include inheritable permissions from this object's parent" is *checked*.   You will notice that for certain users, this box keeps getting unchecked. This is normal behavior due to the inbuilt security of Active Directory. People that are in the following groups will have this flag altered by AD: Account Operators Administrators Backup Operators Domain Admins Domain Controllers Enterprise Admins Print Operators Read-Only Domain Controllers Replicator Schema Admins Server Operators Once the box is cheked, permissions will flow and the user will be set correctly. Even if the box is unchecked, they will function normally as they now has the proper permissions configured. You need to perform this same excercise when enabling users for Lync, but that's another blog. :-)   -Chris

  • OpenGL ES Shader help (Blending)

    - by Chris
    Earlier I required assistance getting to grips with how to retain the alpha channel of a transparent texture in my colourised texture shader program. Whilst playing with that first version of my program (before obtaining the solution to my first requirement), I managed to enable transparency for the whole texture (effectively blending via GLSL), and I quite liked this, and I would now like to know if and how it is possible to retain this blending effect, on top of the existing output without affecting the original alpha channel - as I don't know how to input this transparency via the parameter that is already being provided with the textures alpha channel. A basic example of the blending program I am referring to (minus any other functionality) is as follows... varying vec2 texCoord; uniform sampler2D texSampler; void main() { gl_FragColor = vec4(texture2D(texSampler,texCoord).xyz,0.5); } Where 0.5 is the transparency (blending effect) of the whole texture. This is the current version of my program, which provides the ability to colour a texture according the colour parameter passed to the program, and retains the alpha channel of the original texture. varying vec2 texCoord; uniform sampler2D texSampler; uniform vec3 colour; void main() { gl_FragColor = vec4(colour,1) * vec4(texture2D(texSampler,texCoord).xyz,texture2D(texSampler,texCoord).w); } I need to know if it is possible to apply transparency on top this program, without affecting the original alpha channel which I have already preserved. I hope this makes enough sense, I am sure it is possible, and if so I should imagine it is rather simple, but this has me stumped. Any help much appreachiated. Cheers, Chris

  • Friday Tips #33

    - by Chris Kawalek
    Happy Friday, everyone! Our tip this week is from an excellent white paper written by our own Greg King titled Oracle VM 3: Building a Demo Environment using Oracle VM VirtualBox. In it, Greg gives you everything you need to know to set up Oracle VM Server inside of Oracle VM VirtualBox for testing and demoing. The section we're highlighting below is on how to configure the network interfaces of your virtual machines: VirtualBox comes with a few different types of network interfaces that can be used to allow communication between the VM guests and the host operating system, including network interfaces that will allow the VM guests to communicate with local and wide area networks accessed from your laptop or personal computer. However, for the purpose of the demonstration environment we will limit the network communication to include access just between your desktop and the virtual machines being managed by VirtualBox. The install process for Oracle VM VirtualBox creates a single host-only network device on your laptop or personal computer. Using the host-only network device will allow you to open a browser on your desktop to access the Oracle VM Manager running within the VirtualBox VM guest. The device will only allow network traffic between the VM guests and your host operating system, but nothing outside the confines of your laptop or personal computer. We will need to add a second host-only network since the Oracle VM Server appliance has both eth0 and eth1 configured. You can choose to use eth1 on the Oracle VM Servers or not use them – the choice is yours. But, at least the host side network device will exist if you decide to use it. Greg goes on to describe in detail how to setup the network interfaces, so you can head on over to the paper and get even more info. See you next week! -Chris

  • Friday Tips #4

    - by Chris Kawalek
    It's time once again for our Friday tip. Our question today is about how to determine how much video RAM to allocate for your virtual machines in a VDI deployment: Question: How much video RAM do I really need on my VirtualBox VMs? Answer by John Renko, Consulting Developer, Oracle: The answer is in the VirtualBox admin guide but it's seldom followed correctly, usually resulting in excess unused RAM to be allocated. The formula for determining how much RAM to allocate is shown below for a 32 bit fullscreen 22" monitor supporting 1680x1050: bit depth / 8 x horizontal res x vertical res / 1024 / 1024 = MB RAM Which translates to: 32 bits / 8 x 1680 x 1050 / 1024 / 1024 = 6.7 MB If you wanted to support dual 22" monitors, you would need twice that, so 13.4 MB. Anything in excess of what is needed is readily allocated but not used and would be better suited for running more VMs! Thanks John, that tip should help folks squeeze a little more out of their VDI servers. And remember, if you have a question for us, use hash tag #AskOracleVirtualization on Twitter. We'll see you next week with another tip! -Chris

  • How to ...set up new Java environment - largely interfaces...

    - by Chris Kimpton
    Hi, Looks like I need to setup a new Java environment for some interfaces we need to build. Say our system is X and we need to interfaces to systems A, B and C. Then we will be writing interfaces X-A, X-B, X-C. Our system has a bus within it, so the publishing on our side will be to the bus and the interface processes will be taking from the bus and mapping to the destination system. Its for a vendor based system - so most of the core code we can't touch. Currently thinking we will have several processes, one per interface we need to do. The question is how to structure things. Several of the APIs we need to work with are Java based. We could go EJB, but prefer to keep it simple, one process per interface, so that we can restart them individually. Similarly SOA seems overkill, although I am probably mixing my thoughts about implementations of it compared to the concepts behind it... Currently thinking that something Spring based is the way to go. In true, "leverage a new tech if possible"-style, I am thinking maybe we can shoe horn some jruby into this, perhaps to make the APIs more readable, perhaps event-machine-like and to make the interface code more business-friendly, perhaps even storing the mapping code in the DB, as ruby snippets that get mixed in... but thats an aside... So, any comments/thoughts on the Spring approach - anything more up-to-date/relevant these days. EDIT: Looking a JRuby further, I am tempted to write it fully in JRuby... in which case do we need any frameworks at all, perhaps some gems to make things clearer... Thanks in advance, Chris

  • Friday Spotlight: Network Troubleshooting with Oracle Linux

    - by Chris Kawalek
    Happy Friday, everyone! Our Spotlight this week is on a fantastic new article by Oracle's Robert Chase and posted on Oracle Technology Network. The article steps through, with command line examples, several strategies for tracking down network connectivity issues. From the article: "When applications that use network connectivity for communication are not working, the cause is often a mystery. Despite advances in modern operating systems, many users believe there is no way to directly "see" what's going over the wire, and that often leads to confusion and difficulties when something goes wrong. The reality is that you can actually see what's going over the wire, and there are a number of tools built into Oracle Linux for troubleshooting network issues. This article will help solve some of the mystery and make network connectivity a bit more user friendly." I highly recommend checking this article out, it's a good one! Network Troubleshooting with Oracle Linux  We'll see you next week! -Chris

  • DIA2012

    - by Chris Kawalek
    If you've read this blog before, you probably know that Oracle desktop virtualization is used to demonstrate Oracle Applications at many different trade shows. This week, the Oracle desktop team is at DIA2012 in Philadelphia, PA. The DIA conference is a large event, hosting about 7,000 professionals in the pharmaceutical, bio technology, and medical device fields. Healthcare and associated fields are leveraging desktop virtualization because the model is a natural fit due to their high security requirements. Keeping all the data on the server and not distributing it on laptops or PCs that could be stolen makes a lot of sense when you're talking about patient records and other sensitive information. We're proud to be supporting the Oracle Health Sciences team at DIA2012 by hosting all of the Oracle healthcare related demos on a central server, and providing simple, smart card based access using our Sun Ray Clients. And remember that you're not limited to using just Sun Ray Clients--you can also use the Oracle Virtual Desktop Client and freely move your session from your iPad, your Windows or Linux PC, your Mac, or Sun Ray Clients. It's a truly mobile solution for an industry that requires mobile, secure access in order to remain compliant. Here are some pics from the show: We also have an informative PDF on Oracle desktop virtualization and Oracle healthcare that you can have a look at.  (Many thanks to Adam Workman for the pics!) -Chris  For more information, please go to the Oracle Virtualization web page, or  follow us at :  Twitter   Facebook YouTube Newsletter

  • Perth's ADF Community Event now an open invite

    - by Chris Muir
    Yesterday saw the next ADF Community Event in Perth, and as promised we grew from 15 to 25 attendees (which is going to cause a bit of a problem soon if we keep growing as we're going to run out of powerpoints for laptops). This bimonthly enjoyed presentations from Matthew Carrigy from the Dept of Finance WA on the ADF UI Shell, a small presentation from me about how Fusion Apps uses ADF, and a hands on based on programatically extending ADF BC to call external web services.  For Matt, his first presentation to a user group, with two live demos, all kudos to him for making it look smooth (for the record I hate live demos, I always break something) - thank you Matt! We've already lined up our speakers for the next event in November, and will be inviting yet more customers to this event.  However the event will now move to an open invite, so if you'd like your staff to attend please let me know by emailing chris DOT muir AT oracle DOT com. Alternatively I've had a fair few requests now for an "Intro to ADF" 1 day session so I'll consider this soon.  Certainly if you're interested let me know as this will help organize the event earlier rather than later.

  • Friday Tips #5

    - by Chris Kawalek
    Happy Friday, everyone! Following up on yesterday's post about Oracle VM VirtualBox being selected as the best virtualization solution for 2012 by the readers of Linux Journal, our Friday tip is about that very cool piece of software: Question: How do I move a VM from one machine to another with Oracle VM VirtualBox? Answer by Andy Hall, Product Management Director, Oracle Desktop Virtualization: There are a number of ways to do this, with pros and cons for each. The most reliable approach is to Export and Import virtual machines: From the VirtualBox manager, simply use the File…Export appliance menu and follow the wizard's lead. Move the resulting file(s) to the destination machine; and Import the VM into VirtualBox. This method will take longer and use more disk space than other methods because the configuration files and virtual hard drives are converted into an industry standard format (.ova or .ovf). But an advantage of this approach is that the creator of the virtual appliance can add a license which the importer will see and click-to-accept at import time. This is especially useful for ISVs looking to deliver pre-built, configured and tested appliances to their customers and prospects. Thanks Andy! Remember, if you have a question for us, use Twitter hashtag #AskOracleVirtualization. We'll see you next week! -Chris

  • Friday Tips #6, Part 2

    - by Chris Kawalek
    Here is a question about updating Oracle VM: Question: How can I perform Oracle VM 3 server updates from Oracle VM Manager? Answer by Gregory King, Principal Best Practices Consultant, Oracle VM Product Management: Server Update Manager is a built-in feature of the Oracle VM Manager. Basically, Server Update Manager automatically configures YUM updates on all the Oracle VM Servers, pointing each to our Unbreakable Linux Network (ULN) update channel for Oracle VM. The servers periodically check with our Oracle YUM repository and notify the Oracle VM Manager that an update is available for each server. Actual server updates must be triggered by the Oracle VM administrator – they are not executed automatically. At this point, you can use the Oracle VM Manager to put a server into maintenance mode which live migrates all the running Oracle VM Guests to other Oracle VM Servers in the server pool. Once all the Oracle VM Guests have been migrated, the Oracle VM administrator can trigger the update on the server. The entire process is documented in the Installation and Upgrade Guide of Oracle VM Documentation so I won’t spend time detailing the steps. However, configuring the Server Update Manager is exceedingly simple. Simply navigate to the Tools and Resources tab in the Oracle VM Manager, select the link for Server Update Manager and ensure the following values are added to the text boxes as shown in the illustration below: YUM Base URL: http://public-yum.oracle.com/repo/OracleVM/OVM3/latest/x86_64 YUM GPG Key: file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle Every server in the pool will be automatically configured for YUM updates once you choose the Apply button. Many thanks to Greg and Rick for providing the answers to this week's questions. If you want to ask us something, hit up Twitter and use hashtag #AskOracleVirtualization. See you next week! -Chris

  • Add collection or array to wpf resource dictionary

    - by Chris Cap
    I've search high and low and can't find an answer to this. I have two questions How do you create an array or collection in XAML. I've got an array I want to stick in there and bind to a combo box. My first idea was to put an ItemsControl in a resource dictionary, but the ItemsSource of a combo box expects IEnumerable so that didn't work. Here's what I've tried in my resource dictionary and neither works <ItemsControl x:Key="stateList"> <sys:String>AL</sys:String> <sys:String>CA</sys:String> <sys:String>CN</sys:String> </ItemsControl> <ItemsControl x:Key="stateList2"> <ComboBoxItem>AL</ComboBoxItem> <ComboBoxItem>CA</ComboBoxItem> <ComboBoxItem>CN</ComboBoxItem> </ItemsControl> and here's how I bind to it <ComboBox SelectedValue="{Binding Path=State}" ItemsSource="{Binding Source={StaticResource stateList2}}" > </ComboBox> EDIT: UPDATED I got this first part to work this way <col:ArrayList x:Key="stateList3"> <sys:String>AL</sys:String> <sys:String>CA</sys:String> <sys:String>CN</sys:String> </col:ArrayList> However, I'd rather not use an array list, I'd like to use a generic list so if anyone knows how please let me know. EDIT UPDATE: I guess XAML has very limited support for generics so maybe an array list is the best I can do for now, but I would still like help on the second question if anyone has an anser 2nd. I've tried referencing a merged resource dictionary in my XAML and had problems because under Window.resources I had more than just the dictionary so it required me to add x:Key. Once I add the key, the system can no longer find the items in my resource dictionary. I had to move the merged dictionary to Grid.Resources instead. Ideally I'd like to reference the merged dictionary in the app.xaml but I have the same problem Here's some sample code. This first part required an x:key to compile because I have converter and it complained that every item must have a key if there is more than one <UserControl.Resources> <win:BooleanToVisibilityConverter x:Key="VisibilityConverter" /> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="/ResourcesD.xaml" /> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </UserControl.Resources> I had to change it to this <UI:BaseStep.Resources> <win:BooleanToVisibilityConverter x:Key="VisibilityConverter" /> </UI:BaseStep.Resources> <Grid> <Grid.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="/ResourcesD.xaml" /> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Grid.Resources> </Grid> Thank you

  • Wrap or adorn wpf listview datatemplate

    - by Chris Cap
    I'm attempting to essentially wrap the contents of a DateTemplate in a listview gridview column with a border. What I want to know is if it's possible to supply an adorner that will surround that template so that I don't have to specify the border in every single datatemplate on every column (which is what I'm doing now). I've got something like this, but I know it's not right <Style TargetType="{x:Type ListBoxItem}"> <Setter Property="TemplateContent"> <Setter.Value> <ControlTemplate> <StackPanel> <Border BorderBrush="Green" BorderThickness="1"> <AdornedElementPlaceholder /> </Border> </StackPanel> </ControlTemplate> </Setter.Value> </Setter> </Style> This complains that Templatecontent is not a valid type. I've also tried with DataTemplate and that doesn't work either (understandably so). I know I could just create a DataTemplate, however the content for each column is different. At the very least, it binds to different fields. I'm wondering if there's a solution using a dynamic resource, but I don't know much about it. Thanks for your help EDIT: here's a sample of my listview <ListView ItemsSource="{Binding Path=OrderLines}" ItemContainerStyle="{StaticResource ResourceKey=ListViewItemContainerStyle}"> <ListView.View> <GridView> <GridViewColumn> <GridViewColumn.CellTemplate> <DataTemplate> <TextBox MaxWidth="30" Width="30" MaxLength="2" Text="{Binding Path=Quantity,ValidatesOnDataErrors=True}" /> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> <GridView> <ListView.View> </ListView> Essentially I want to wrap that text box in the data template and any other items in additional columns.

  • Hypervisor load on local disks

    - by Chris
    Hi, What is the I/O load on the local disk system for the host OS in XenServer ? I can't find this info anywhere. As we have a SAN for the VMs themselves, can we get away with cheap controller / SATA disk in raid-1 for the hypervisor ? We won't boot from the SAN as it seems prone to problems. Thanks, Chris

  • wpf display staggered content

    - by Chris Cap
    I am trying to display a rather dynamic list of data in WPF. I have essentially a LineItem class that contains a list of strings and a line type. The line type separates different categories of line items. All line items with the same type should be displayed the same and their data should line up. For example, this list will contain an order summary. And the there will be a line type that represents something with a width and height. The width and height must line up vertically. However, there may be other line types that don't have to line up vertically. I want to produce a table similar to what you see below: ------------------------------------------------------------------ | some content here | some more content here | last content here | |----------------------------------------------------------------| | some content here | | last content here | |----------------------------------------------------------------| | spanning content that is longer then most | last content here | |----------------------------------------------------------------| | some content that can span a really long distance | ------------------------------------------------------------------ I attempted to do this by creating ListView with a single column that had a datatemplate that contained a grid with a fixed number of fields and then bind to the Colspan value. Unfortunately, this didn't work. I ended up with incorrect or overlapping content anytime I tried to do a column span. Here's the XAML I was working with <ListView ItemsSource="{Binding}" > <ListView.View> <GridView> <GridViewColumn Header="Content"> <GridViewColumn.CellTemplate> <DataTemplate> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition /> <ColumnDefinition /> <ColumnDefinition /> </Grid.ColumnDefinitions> <TextBlock Grid.Column="0" Grid.ColumnSpan="{Binding Path=Tokens[0].ColumnSpan}" Text="{Binding Path=Tokens[0].Content}" ></TextBlock> <TextBlock Grid.Column="1" Grid.ColumnSpan="{Binding Path=Tokens[1].ColumnSpan}" Text="{Binding Path=Tokens[1].Content}" ></TextBlock> <TextBlock Grid.Column="2" Text="{Binding Path=Tokens[2].Content}"></TextBlock> </Grid> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> </GridView> </ListView.View> And here's the classes I was binding to public class DisplayLine { public LineType Linetype { get; set; } public List<Token> Tokens { get; set; } public DisplayLine() { Tokens = new List<Token>(); } } public class Token { public string Content { get; set; } public bool IsEmpty { get { return string.IsNullOrEmpty(Content); } } public int ColumnSpan { get; set; } public Token() { ColumnSpan = 1; } } Does anyone have any suggestions of maybe a way of making this work. I may be taking the wrong approach. I'm trying to avoid any solutions where I explcitily build something in the code behind as I'm using the MVVM pattern so it has to be something that I can bind from exposed through the controller. My intial plan was to create a factory and separate classes that display the data differently based on type. However, I'm struggling coming up with a strategy for this using MVVM as I really can't just build something and display it. I have toyed with the idea of making some kind of UI service class that is injected, but it would still require some pretty detailed UI information from the controller to do it's work.

  • Google Chrome on Mac OS X, full screen option is greyed out, why?

    - by Chris Kimpton
    When I first installed Chrome the menu option for "full screen" was enabled and worked, but for the last few months is been greyed out/disabled. Is it just me or perhaps there is a bug which is why its disabled? I tried deleting the installed version and downloading a new copy, to no avail - but perhaps there is a setting in my local preferences that could be disabling it. Thanks in advance, Chris

  • vmware windows7 professional changing ip addresses

    - by chris hough
    is there a way to fix your windows 7 professional guest host os ipaddress so it does not change every time you startup? I am currently using NAT for networking and would like to remain using this networking method if possible. In older versions of windows this never used to be a problem in vmware so I am wondering if I am missing a setting in windows 7 professional or in vmware. thank you for your help, chris

  • Python list as *args?

    - by Cap
    I have two Python functions, both of which take variable arguments in their function definitions. To give a simple example: def func1(*args): for arg in args: print arg def func2(*args): return [2 * arg for arg in args] I'd like to compose them -- as in func1(func2(3, 4, 5)) -- but I don't want args in func1 to be ([6, 7, 8],), I want it to be (6, 7, 8), as if it was called as func1(6, 7, 8) rather than func1([6, 7, 8]). Normally, I would just use func1(*func2(3, 4, 5)) or have func1 check to see if args[0] was a list. Unfortunately, I can't use the first solution in this particular instance and to apply the second would require doing such a check in many places (there are a lot of functions in the role of func1). Does anybody have an idea how to do this? I imagine some sort of introspection could be used, but I could be wrong.

  • asp.net mvc 2 multithread

    - by Chris Cap
    I'm getting some weird behavior in asp.net MVC2 (at least it's not what I'm expecting). I have a controller httppost action that processes credit cards. I'm setting a session variable on the server to let me know if a user has attempted to process a card. I clear that session variable when I'm done. I am doing some very quick posts to test the process and the session variable is coming back null everytime because I clear the session variable at the end of the process. I have some debug prints that show me that the all requests are processed synchronously. That is...the first attempt occurs, it fails, session variable is cleared, second attempt tries and fails and the variable is cleared, etc... My first thought was that this was a side effect of debugging and that it just lined requests up for debugging purposes using the local webserver. So I put it on a development server and the same thing is occurring. Multiple submits/posts are processed synchronously. I even put a System.Threading.Sleep in there to make sure it would stop right after I set the session variable and it still won't even START the second request until the first is done. Has anyone else seen this behavior? My understanding was that a worker process was spawned for each request and that these actions could happen asychronously. Here's some psuedo code if (Session["CardCharged"] != null) return RedirectToAction("Index", "Problem"); Session["CardCharged"] = false; //starting the process System.Threading.Thread.Sleep(10000); //charge card here if (!providerResponse.IsApproved) { System.Diagnostics.Debug.WriteLine("failed"); Session["CardCharged"] = null; //have to allow them to charge again since this failed return View(myModel); } Session["CardCharged"] = true; return RedirectToAction("Index", "OrderComplete"); I should mention that my code ALWAYS fails the credit card check for testing purposes. I'm trying to test the situation where processing is STILL occurring and redirect the user elsewhere. I have set a dummy session variable elsewhere to assure that the session id "sticks". So I know the session id is the same for each request. Thanks

  • Keep PyGTK Button from Resizing on Label Change

    - by Cap
    I'm working on a PyGTK app with some Buttons that, when clicked, give a text entry dialog, then set the text on the button to whatever was entered in the box. The problem is that if the text is longer than the button can show, the button changes size to accomodate. How do I keep GTK Buttons from resizing when the text changes?
