Status of Windows Shell Extensions Support

Hi,
Are Windows Explorer Shell Extensions viable (Column Extensions in particular)? If so, is C++/ATL the best approach?
All the article/docs I search seem to be 5-10 years old, and it appears .NET shell extensions are not recommended by Microsoft. I have been testing some .NET shell extensions with quite a bit of difficulty.

Are Windows Explorer Shell Extensions viable (Column Extensions in particular)?
I don't think column extensions have been viable since XP.
All the article/docs I search seem to be 5-10 years old, and it appears .NET shell extensions are not recommended by Microsoft.
Different camps at MS have said different things, especially when .Net
4 came out, but I think the consensus is that it's not recommended to
do shell extensions in .NET - however, people still do them! :(

  • Windows shell extension / explorer extions

    Hi,
    I'm getting frustrated with an explorer plugin that lets me view images and their thumbnails within Windows Explorer. If I was to write something myself, where should I begin. I have a few tabs open on 'writing shell extensions' [2002], registering shell
    extension handlers [C lang], etc. Of particular note is 'EZShellExtensions.net v2013' But I'm not sure what the situation is in 2014 with writing a custom thumbnail / image viewer.
    I would prefer C#, but I've been working with C++ a bit lately (hopefully getting a bit better at using it) so if that were the preferable approach, I could probably tackle it.
    I guess I was concerned that a lot of the material I'm seeing is quite old and I'm yet to find a recent article on writing extensions.
    Thanks for any advice.

    The overall documentation root is
    here.  If you're not familiar with implementing COM interfaces, I can see how it could be a bit daunting to get started.  If you're open to C++, if you make an ATL project, you can add a class that has a lot of the support built in already
    for you.  Click on Add Class, Select ATL->ATL Simple Object, give it a name, click next, and you'll be at the File Type Handler Options screen.  You can choose to make a preview handler, thumbnail handler, or search handler; the wizard will generate
    the necessary skeleton code for you.

  • Gnome-shell-extension-windows-navigator styling differs from the AUR

    I installed gnome-shell-extension-windows-navigator 3.0.1-0.20110513 from extra. When I used the AUR package, the styling was better.
    1) When hitting Ctrl the workspace number was displayed.
    2) When hitting Alt the window numbers were shown in the same style as close button just on the left side of the window. Now they are in the windows' top left corner and they are hard to seen.
    Is there a way to get that styling? I think I could get the extension's stylesheet.css from the AUR package, but it will be overwrite with every upgrade.thumbs

  • Requesting 64-bit Shell Extension DLL

    Adobe support website states that Adobe Acrobat Pro is compatible with 64-bit versions of Windows. I am using Windows Vista Ultimate 64-bit and Acrobat X Pro, and I am missing the PDF tab from the file properties dialog box. This is because Explorer is a 64-bit program (since it is running on Windows Vista 64-bit). But if I do the same within the Open dialog box in Acrobat Pro I can see the PDF tab.
    In Windows Explorer:
    Open Windows Explorer (Win+E)
    Navigate to Desktop.
    Right click on a PDF file.
    Click Properties.
    See fi you can see the PDF tab in the dialog box that appears. If you are on 64-bit Windows Vista (maybe even Windows 7) you will not see this option.
    However, in Adobe Acrobat X Pro:
    Open Acrobat X Pro.
    Click File, then Open (Ctrl+O).
    Navigate to Desktop.
    Right click on a PDF file.
    Click Properties.
    Now you should be able to see the PDF tab in the file properties dialog box. Why it appears in Acrobat Pro but not when viewing the same dialog box from Explorer is because Acrobat Pro is a 32-bit software.
    The change I want to see is that the PDF tab will be visible, regardless of if you are viewing it from within the Open dialog box in Acrobat Pro or from Window Explorer. You need to either provide a fully functional and full featured 64-bit version of Acrobat Pro, or you need to provide a working 64-bit Shell Extension for compatibility with 64-bit Windows and 64-bit Explorer, and keep Acrobat Pro as 32-bit only.

    JGreatness,
    I could tell you, but I'd rather put the pressure on Oracle to deliver a 21st Century product. If you pay for maintenance, then you can log in and place an enhancement request.
    Now, if you don't care about support, then you can run the 32-bit application on Windows 2008R2 with a little tweaking. The main issue is with the printing to PDF. You need a couple of 64-bit DLL files for the Amyuni PDF printer. The files and associated installation instructions used to be available in the knowledgebase, but were later pulled.
    The best you can do for now and still receive support is stick with 32-bit and maximize your application and Java memory settings. I don't think the WebLogic option will gain you anything, as the 'tested configurations' document only lists 32-bit Windows as the host operating system, regardless if you use JBOSS or WebLogic. Speculating, I would say the main issue revolves around 64-bit Java, not the operating system or web application. If Oracle is going to continue to utilize the JDK and Java elements and deliver a 64-bit product, then they will have to convert all Java objects to 64-bit. Correct me if I'm wrong. Also, the executable service file they provide is 32-bit and would need to be converted.
    Sadly, they only provide support for what was, at one time, the most common platform among many CM shops. We need more options, but that increases Oracle's development and support costs. I would prefer to lose the Microsoft Office dependency for letter templates and log exports and run the whole thing on 64-bit Linux, but we can't have everything.
    As noted in a previous post, I suppose you could go ahead and get the DLL's via a purchase from Amyuni.
    I don't know if we could post the DLL's and instructions on the Yahoo message board.

  • Shell extensions and key stroke capturing...

    Hello. Me and my team are working on a project which converts English input from a QWERTY keyboard to Unicodes local Indian languages like Kannada, Tamil etc. We're using Java and SWT for UI. The program should run in such a way that once the program is running, wherever the user enters, he should be able to see the unicodes/indian language output. That is, the program should be a shell extension or a it must run in the background and capture the keystrokes of the active window the user is using. We are developing this software for both windows and linux. So is it possible to create shell extensions or implement the background window(process)?
    Are there APIs in linux to capture key strokes?? Is it possible to use Win32 WinHooks in windows to capture the key strokes??
    Edited by: abhinav_zoso on Jan 8, 2009 11:35 PM

    Are there APIs in linux to capture key strokes?? Is it possible to use Win32 WinHooks in windows to capture the key strokes??Those are not java questions. Programming forums specific to the OS will provide the answer. Or docs for that matter.
    ... which converts English input from a QWERTY keyboard to Unicodes local Indian languagesThat by itself doesn't make much sense unless you are talking about language translation rather than characters.
    The ASCII code set which would normally represent the entire english character set, is part of unicode. So no conversion needed.
    But perhaps you merely wish to map set of keystrokes into other characters? I would strongly suppose that at least windows already supports this in some format so I am not sure why you need java in the mix. Certainly, for example, if you had a computer set up to display another language character set and you want to put a key stroke interceptor in place that should be possible. And if the computer is not set up to display the language then what is the point?

  • Using Open Picture Window Fever extension ver. 4.0.1

    I have set up a page in a web site I am building (I am not a pro!) with about 20 thumbnails and added the Open Picture Window Fever extension to allow the user to see a larger image when they click a thumbnail. Here is the script:
    <div class="figure">
          <p>
            <img src="../../siteimages/ThumbNails/Window-hymns-TH.jpg" alt="Hymns" width="150" height="277" onclick="openPictureWindow_Fever('','../../siteimages/Large/Window-hymns-LG.jpg','350','646','Large image','200','200')"
    />
          <p> Hymns
    </div>
    The problem has been that sometimes for no reason I can fathom, the path to the larger image suddenly gets changes to 'undefined'. This has happened a couple of times but the other day after I had finished all the images and tested it live, every large image reference had been changed to 'undefined'. So I had to redo the Fever extesnion for each one. The only thing I recall doing after I had tested the page live was that I Put the entire site to make sure that all changes I had made to various pages were uploaded.
    Can anyone suggest what might have caused this problem? Also is there another extension that I can try that does the same thing?
    Thanks, Alan
    PS I posted this in the general forum and it was suggested that I post it here.

    You may want to ask this in the Dreamweaver Extensions forum or the Extension Developer's own support forum. You will likely get faster answers there.

  • Saved files as .PSD now they are "Windows Shell Common Dll" and won't open?

    I am having a problem with opening some files in Photoshop. I am using Photoshop CS5.1 Extended (Version 12.1) and have Windows 7 64 bit SP1 OS.
    I am trying to open a few templates I made in PhotoShop for a client and they worked fine when I used them 3 weeks ago. All were saved as .psd documents. Now when I go to open them they no longer have the PS icon (to show they would be opened by PhotoShop). When I try to open them I get "Could not complete your request because it is not the right type of document." I have had this problem once before but it is confusing to me because 2 of the other similar .psd files I saved at the same timeframe(separate elements for the temlate) are perfectly fine, only the ones I need do not want to open.
    I checked file properties and it claims these files are now Windows Shell Common Dll files. Any ideas?

    I guess you were able to open them in photoshop with open as.
    In the future you should probably try to avoid using periods in the image file names other than for the file type extension.
    You could use - or_ in place of the periods as in VotePedia Invoice 1_5_13  or VotePedia Invoice 1-5-13
    Also, as Noel suggested, going into Control Panel>Appearace and Personalization>Folder Options>View
    and unchecking Hide extensions for known file types will help as well.

    You can try it later. I had this issue long ago and waited one day.
    You also try those two solution:
    1.redeploy your project to worker role and enable the RDP setting (see this blog
    2.recklessly, you could delete your worker role and redeploy it. The error will be disappeared.

  • Video does not play: "Either windows doesn't support the item's file format......"

    Error message
    "Either windows doesn't support the item's file format or the content doesn't match the extension"
    I have both a Yoga and a Thinkpad 2. The Yoga is running Win 8 and the Thinkpad 2 has 8.1 Preview.
    I have copied multiple video files which are in either .avi or .mp4 containers.
    Some will play and some will not. I have installed all sorts of codec packages and players and the problem is the same. I though it might be a container problem so I tried to convert the file and the converter I used did not work.
    Searched the Internet and nothing really useful was found.
    Then I discovered a common thread. In the files that played, the codec information displayed when checking in properties and the ones that did not play, did not have the information.
    I have a video file on a USB flash drive and checked the properties and the information was there and I could play it from the flash drive. I copied it to my desktop and the file would not play. In checking, the codec information was not present.
    There seems to be an error in copying files where the requisite codec information is not being transferred.
    I have tried this multiple times and multiple permutations of transferring. Sometimes it will play from the desktop and will not play after transfer to the microSD card.
    Each time when it plays, the information is there and each time it does not play, the information is not there.

  • PS5 running sluggish adn saving files in windows shell common

    I recently started working with PS5 and have been encountering some errors recently. 
    At first my files were being saved as PSD files, then all of a sudden they began to be saved as windows shell comer files.  When I try to open them it says I need to find a program on the web to open photo. 
    I also am wondering about hte fact that it seems to take all my physical RAM memory when I have PS5 in use, I have 4GB of RAM and when I use the program I am at 91% + of memory usage.  It is a 64 bit operating system and if needed to know it is a M450 processor at 2.4 GHz.
    Seems that PS5 has really become sluggish since this problem with the way the file saves.  When working in the program it freezes up temporary and takes a long time to resize a photo and other functions.  I also have Perfect size and lightroom3.  Not sure if this is needed for a helpful answer, but maybe.  LOL 
    Thanks for any advice or assitence.. 

    Generally speaking, .PSD is a good format to save your edits in because it's lossless and can maintain all your layers, channels, and other fancy Photoshop features.
    You need to check the pixel count on saving as well.  If you've used Perfect Resize to radically increase the pixel count of the image you're saving this could help explain some of the speed issues you're seeing.  With most image work it's always good to keep the pixel dimensions in mind.
    If you're using Windows 7 here's how to show the file extension:
    1.  Click the Start orb and type folder into the search box.  When Folder Options comes up, click it.
    2.  Click the View tab.
    3.  Uncheck the [  ] Hide extensions for known file types box.
    Now Explorer windows and File Open/Save dialogs will show you the file extension.
    While you're editing Photoshop will normally gradually increase its memory use up to the limit you specify in Edit - Preferences - Performance, then hold onto it.  This is by design.
