  • Using URL Rewrite with QDIG

    - by The Official Microsoft IIS Site
    One of the applications that I like to use on my websites it the Quick Digital Image Gallery (QDIG) , which is a simple PHP-based image gallery that has just enough features to be really useful without a lot of work on my part to get it working. (Simple is always better - ;-] .) Here's a screenshot of QDIG in action with some Bing photos: (Click to enlarge photo.) The trouble is, QDIG creates some really heinous query string lines; see the URL line in the following screenshot for an example:...(read more)

  • Digitally Signed Malware on the Rise

    Brought to the forefront in 2010 with Stuxnet, the infamous worm aimed at sabotaging industrial infrastructure, the use of stolen digital certificates is relatively new. Stuxnet's creators digitally signed its rootkit components with stolen certificates from JMicron and RealTek, a pair of semiconductor manufacturers. The worm's existence and complexity caught the security community by surprise. In fact, many researchers predicted that malware creators would begin adopting the same technique to work around driver signature enforcement employed by Microsoft in its 64-bit versions of Windows V...

  • certificate for website login

    - by Mario
    Not sure if this belongs here or at serverfault... I've seen websites where, to login to the website, requires a digital certificate to be installed for the user logging in. As far as I can tell, this certificate is in addition to the website using an SSL certificate (https) I'm just looking to be pointed in the right direction on how to code for this (apache / php hopefully), who issues these certificates (must it be a trusted var or can I ?) or even what to search for via google. -Mario

  • Is there an Ubuntu alternative to iExplorer (formerly iPhone Explorer)?

    - by nerdabilly
    I'm trying to view the entire contents of my iPhone in Ubuntu 10.04. I'm able to mount and view the digital media folders, but I'm looking for behavior more like the Mac/Windows iExplorer app that will list the /var folder as well as Applications, etc rather than just making it look like an external filesystem. I've found a few options that require jailbreak but I'd rather not go that route if it's at all possible. Thanks!

  • How do you reset a USB device from the command line?

    - by Casey
    Is it possible to reset the connection of a USB device, without physically disconnecting/connecting from the PC? Specifically, my device is a digital camera. I'm using gphoto2, but lately I get "device read errors", so I'd like to try to do a software-reset of the connection. From what I can tell, there are no kernel modules being loaded for the camera. The only one that looks related is usbhid.

  • Having Fun with Coding4Fun&rsquo;s Windows Phone 7 Controls

    - by mbcrump
    I’m a big believer in having a hobby project as you can probably tell from the first sentence in my “personal webpage using Silverlight” article. One of my current hobby projects is to re-do my current WP7 application in the marketplace. I knew up front that I needed a “Loading” animation and a better “About” box. After starting to develop my own, I noticed a great set of WP7 controls by Coding4Fun and decided to use them in my new application. Before I go any further they are FREE and Open-Source. It is really simple to get started, just go to the CodePlex site and click the download button. After you have downloaded it then extract it to a Folder and you will have 4 DLL files. They are listed below: Now create a Windows Phone 7 Project and add references to the DLL’s by right clicking on the References folder and clicking “Add references”.   After adding the references, we can get started. I needed a ProgressOverlay animation or “Loading Screen” while my RSS feed is downloading. Basically, you just need to add the following namespace to whatever page you want the control on: xmlns:Controls="clr-namespace:Coding4Fun.Phone.Controls;assembly=Coding4Fun.Phone.Controls" And then the code inside your Grid or wherever you want the Loading screen placed. <Controls:ProgressOverlay Name="progressOverlay" > <Controls:ProgressOverlay.Content> <TextBlock>Loading</TextBlock> </Controls:ProgressOverlay.Content> </Controls:ProgressOverlay> Bam, you now have a great looking loading screen. Of course inside the ProgressOverlay, you may want to add a Visibility property to turn it off after your data loads if you are using MVVM or similar pattern.   Next up, I needed a nice clean “About Box” that looks good but is also functional. Meaning, if they click on my twitter name, web or email to launch the appropriate task. Again, this is only a few lines of code: var p = new AboutPrompt(); p.VersionNumber = "2.0"; p.Show("Michael Crump", "@mbcrump", "[email protected]", @"http://michaelcrump.net"); A nice clean “About” box with just a few lines of code! I’m all for code that I don’t have to write. It also comes with a pretty sweet InputPrompt for grabbing info from a user: The code for this is also very simple: InputPrompt input = new InputPrompt(); input.Completed += (s, e) => { MessageBox.Show(e.Result.ToString()); }; input.Title = "Input Box"; input.Message = "What does a \"Developer Large\" T-Shirt Mean? "; input.Show(); I also enjoyed the PhoneHelper that allows you to get data out of the WMAppManifest File very easy. So for example if I wanted the Version info from the WMAppManifest file. I could write one line and get it. PhoneHelper.GetAppAttribute("Version") Of course you would want to make sure you add the following using statement: using Coding4Fun.Phone.Controls.Data; You can’t have all these cool controls without a great set of Converters. The included BooleanToVisibility converter will convert a Boolean to and from a Visibility value. This is excellent when using something like a CheckBox to display a TextBox when its checked. See the example below: The code is below: <phone:PhoneApplicationPage.Resources> <Converters:BooleanToVisibilityConverter x:Key="BooleanToVisibilityConverter"/> </phone:PhoneApplicationPage.Resources> <CheckBox x:Name="checkBox"/> <TextBlock Text="Display Text" Visibility="{Binding ElementName=checkBox, Path=IsChecked, Converter={StaticResource BooleanToVisibilityConverter} }"/> That’s not all the goodies included. They also provide a RoundedButton, TimePicker and several other converters. The documentation is great and I would recommend you give them a shot if you need any of this functionality. Btw, thank Brian Peek for his awesome work on Coding4Fun!  Subscribe to my feed

  • Anatomy of a .NET Assembly - Signature encodings

    - by Simon Cooper
    If you've just joined this series, I highly recommend you read the previous posts in this series, starting here, or at least these posts, covering the CLR metadata tables. Before we look at custom attribute encoding, we first need to have a brief look at how signatures are encoded in an assembly in general. Signature types There are several types of signatures in an assembly, all of which share a common base representation, and are all stored as binary blobs in the #Blob heap, referenced by an offset from various metadata tables. The types of signatures are: Method definition and method reference signatures. Field signatures Property signatures Method local variables. These are referenced from the StandAloneSig table, which is then referenced by method body headers. Generic type specifications. These represent a particular instantiation of a generic type. Generic method specifications. Similarly, these represent a particular instantiation of a generic method. All these signatures share the same underlying mechanism to represent a type Representing a type All metadata signatures are based around the ELEMENT_TYPE structure. This assigns a number to each 'built-in' type in the framework; for example, Uint16 is 0x07, String is 0x0e, and Object is 0x1c. Byte codes are also used to indicate SzArrays, multi-dimensional arrays, custom types, and generic type and method variables. However, these require some further information. Firstly, custom types (ie not one of the built-in types). These require you to specify the 4-byte TypeDefOrRef coded token after the CLASS (0x12) or VALUETYPE (0x11) element type. This 4-byte value is stored in a compressed format before being written out to disk (for more excruciating details, you can refer to the CLI specification). SzArrays simply have the array item type after the SZARRAY byte (0x1d). Multidimensional arrays follow the ARRAY element type with a series of compressed integers indicating the number of dimensions, and the size and lower bound of each dimension. Generic variables are simply followed by the index of the generic variable they refer to. There are other additions as well, for example, a specific byte value indicates a method parameter passed by reference (BYREF), and other values indicating custom modifiers. Some examples... To demonstrate, here's a few examples and what the resulting blobs in the #Blob heap will look like. Each name in capitals corresponds to a particular byte value in the ELEMENT_TYPE or CALLCONV structure, and coded tokens to custom types are represented by the type name in curly brackets. A simple field: int intField; FIELD I4 A field of an array of a generic type parameter (assuming T is the first generic parameter of the containing type): T[] genArrayField FIELD SZARRAY VAR 0 An instance method signature (note how the number of parameters does not include the return type): instance string MyMethod(MyType, int&, bool[][]); HASTHIS DEFAULT 3 STRING CLASS {MyType} BYREF I4 SZARRAY SZARRAY BOOLEAN A generic type instantiation: MyGenericType<MyType, MyStruct> GENERICINST CLASS {MyGenericType} 2 CLASS {MyType} VALUETYPE {MyStruct} For more complicated examples, in the following C# type declaration: GenericType<T> : GenericBaseType<object[], T, GenericType<T>> { ... } the Extends field of the TypeDef for GenericType will point to a TypeSpec with the following blob: GENERICINST CLASS {GenericBaseType} 3 SZARRAY OBJECT VAR 0 GENERICINST CLASS {GenericType} 1 VAR 0 And a static generic method signature (generic parameters on types are referenced using VAR, generic parameters on methods using MVAR): TResult[] GenericMethod<TInput, TResult>( TInput, System.Converter<TInput, TOutput>); GENERIC 2 2 SZARRAY MVAR 1 MVAR 0 GENERICINST CLASS {System.Converter} 2 MVAR 0 MVAR 1 As you can see, complicated signatures are recursively built up out of quite simple building blocks to represent all the possible variations in a .NET assembly. Now we've looked at the basics of normal method signatures, in my next post I'll look at custom attribute application signatures, and how they are different to normal signatures.

  • Windows 7 Not Recognizing Camera Nor iPhone as Camera

    - by taudep
    I've been struggling with this one for a few days. I've recently upgraded an older computer to Windows 7 Home Premium. Neither my digital camera (A Canon SD1200IS) nor iPhone are ever detected as cameras, nor ever show up as accessable in Explorer. With the Canon camera, no driver is required. It's supposed to work with the default Windows 7 drivers. However, in the Control Panel's Device Manager, I'm always seeing a yellow icon next to the "Canon Digital Camera" device. I've uninstalled the device and let Windows attempt to reinstall, but it can never find a driver to install. With the iPhone, it's very similar. One big difference, though, is that iTunes can see the iPhone and back it up, etc. However, again when I go to the Device Manager, there's a yellow icon next to the iPhone. I've uninstalled iTunes, reinstalled, rebooted, deleted drivers, and let Window try to reinstall the driver, but it can never find the driver. So there seems to be some correlation that my machine can't detect cameras properly, and that it might be even a lower-level type of driver I'm struggling with. I know that USB however, does work, because I have have an external drive hooked into the machine. I've gone through the web and tried two hours worth of fixes, without success. I feel like if I can get the Canon camera detected, then the iPhone will be on it's way to being fixed too. BTW, I couldn't really find anything of use in the Event viewer. Any and all suggestions welcome.

  • Apple video adapters: Mini-DVI to DVI + DVI to video?

    - by Ken
    I have: a Macbook (which has Mini-DVI output) an Apple Mini-DVI to DVI adapter (so I can hook up my Macbook to my DVI LCD) a Mac mini (which has DVI output) I see that I can get a DVI-to-Video (s-video and composite) adapter from Apple that will let me hook up my Mac mini to my TV set (which has only component, s-video, and composite -- nothing digital). So far so good. Question: Will that same adapter also let me hook my Macbook to my TV? That is, can I hook Macbook - Mini-DVI to DVI - DVI to video - TV set, and see picture? I know there are digital/analog/integrated variants of DVI, and it's not at all clear to me what pins these things have and what signals they're sending. One website I found suggested that it would work, and another suggested that it wouldn't even physically connect. So I'm looking for, ideally, someone who's actually tried it, or has these adapters sitting around to try. I know I can buy 2 adapters (Mini-DVI to Video, and DVI to Video) to do this, but at $20 a pop I'll avoid that if at all possible.

  • Which HDD brand do you ..trust

    - by Shiki
    Okay it says its 'subjective' but I believe it's not. Basically I want to ask the community about your preference. Not really 'preference' but actual experience. Like if you never had a problem with Western Digital, then write that in an answer, or if there is one with WD, just vote it up. And so on. (Heard so many stories, experiences. I only had Samsung, Maxtor, WD, Seagate HDDs. Samsung died with bad blocks, had anomalies. Maxtor died so fast I couldn't even try it really and it's really hot, loud. Seagate is just as loud as a jet plane, and moderately hot. My WD (green) is quiet, really cool and somewhat fast. That's all I have about experiences. So I would say Western Digital in an answer (OR Hitachi. Never had one yet, but every expert I know says I should get one since they even had problems with WD but Hitachi seems to be ok. (My laptop comes with Hitachi hdd but I don't think its really relevant.)) Basically I mean desktop 7200RPM HDDs here. Well.. notebook HDDs are ok also, but no raptor/scsi/server ones. Hope you get what I meant and it won't get closed.

  • Disaster recovery backup of files/photos for personal use

    - by Renesis
    I'm looking for the best method to store a backup of important files and 5+ years of digital photos that is safe from some type of fire/flood disaster in my home. I'm looking for: Affordable: Less than $100/yr or first-time cost. Reliable: At least a smaller chance of failing than there is of fire or flood Easy for initial backup and to add to, and at least semi-easy to recover. I recently purchased a small home safe for physical vitals. It was inexpensive, solid, and is fire/water safe. If I had a physical copy of the digital files, the safe would work fine for this, but I don't know what to store in it that adequately meets the requirements above. Hard drive - I read that the danger of it not spinning up makes a hard drive a bad choice for this type of storage, although it was my first thought and would definitely be the simplest choice - very easy to take out once a month and add files to. DVDs - Way too much of a hassle for both backup and restore. Tape - No idea on the affordability of this option Online - Given that I have at least 300GB already and ever-increasing megapixels means ever-bigger files, and my ISP upload is about 2Mb at the best, this just doesn't sound like a good option for me, but I could be convinced. Other - Have I missed something? Also, I'm already covered both for sync between computers (Dropbox) and a nightly backup of these files (External HDD). The problem with the nightly backup is obviously that it's always with the computer and in a disaster would be destroyed along with it. Is anyone else doing something similar? Is the HDD as poor of a choice as I read, or is it a feasible option? Maybe two to reduce the likelihood of failure?
