Tales from the Evil Empire

Hello

I think this album handler is ideal for building photo albums in an intranet, where people have file access to the server via a share. So upload is simple...

Unfortunately the album handler is not working on Windows 2003 server. No such problems on Windows 2000 server.

I get the follwoing error:

Parser Error Message: User control source files must have a .ascx file extension.

and the follwing line is highlighted red:

Line 2:  <%@ Register Src="~/album.ashx" TagPrefix="photo" TagName="album" %>

Do you have a hint how to get the album running on Windows 2003? Or do you know of another product offering the same functionality?

Thank you!

If you're getting the "User control source files must have a .ascx file extension." error and you have framework 2.0 installed, then you probably have the virtual directory configured to use framework 1.1.  On my machine 1.1 is default and I have to set it to 2.0 explicitly in IIS.

I was super-excited to learn that Andrew Grant was able to run the Photo Handler unmodified on Windows

i was trying to download the code to intrigate into my home server and i keep getting the following message

The GotDotNet site is being phased out

  Microsoft will be phasing out most features of the GotDotNet site by Summer 2007.

  GotDotNet Workspaces and Private Workspaces have been phased out        More about the GotDotNet phase-out

is the code still available for download and if so where can i get it?

Hello,

I like your Photo Album handler 2.0 very much, but I've a problem.

Ich can't publish the website.

Here is the errormessage (sorry - it's in german):

"Für die Erweiterung .ashx ist kein Buildanbieter registriert. Sie können einen im <compilation><buildProviders>-Abschnitt in machine.config oder web.config registrieren. Stellen Sie sicher, dass das BuildProviderAppliesToAttribute-Attribut den Wert Web oder All enthält.

I:\xxx\AlbumHandler2_1_\Default.aspx"

Could you help me please?

bye Anke

But I can't publish the website on my own Desktop PC. It runs only with the cassini, ans if I like to publish the Website, I get an Buil-Error.

I've try to add the Build-Handler to the project (in the web.config) but it dosn't works.

I have an other Project width a Http-Handler an this project I can publish. I works width Asp.Net since some years, but I havn't wrote a Http-Handler sometimes. I don't know, that I can makew :(

I have try to publish the Project at an other PC, but I have the same Error-Message :(

ciao Anke

Sorry, but I think you don't understand me. I can copy the files at my Server (It's my own Server an I can take the settings self) - this go. But i can't publish the Website (Project --> Publish Website). Then I get the error.

I like to publish my website, because I don't like to have the CS-Files at the Server. I could publish my total Website-Project ans then I could copy the Photo-Handler later to the published Sites. But this is not that I want.

I use the MyWebPagesStarterKit - it's also from codeplex.com (www.codeplex.com/.../ProjectReleases.aspx). Where are Http-Handler inserted too. But this Project I can publish without problems.

Doo you understand the problem?

ciao Anke

So, I hav made a screenshot. I have Open your Project width Visual Studio 2005. When I try to publish the project. But I get only the error which you can see in the picture in the bottom.

picasaweb.google.com/.../photo

I hav found an other german person, which has the same problem. See: www.mycsharp.de/.../thread.php (sorry, it's in german)

ciao Anke

The photohandler control is great - thanks Bertrand :)

One key point to note is to make sure you get version V2.2.2d (not the latest version) of the MetaDataExtractor - otherwise you'll get a 'The type or namespace name 'Directory' does not exist in the namespace 'com.drew.metadata' (are you missing an assembly reference?)' error.

I needed to specify some directories I wanted to omit from the control (and couldn't see anywhere I could do this with the current control) so I added a few lines of code, which I blogged about here: neilkilbride.blogspot.com/.../net-photo-gallery-control-photohandler.html

I too am having the problem with subdirectories.  I have everything in year folders and then month then activity.  I can click all the way thru but the last folder I cannot view anything inside it.  I get thumbnails but cannot get into the folders.  any ideas?

Dave P

I'm having what is probably a minor issue with the handler. I have it running on Windows Server 2003, and the index page of folder thumbnails comes up fine, but it won't do anything else. When I click on any of the folders, nothing happens. This seems like a Javascript issue as no ASP errors come up. Have tried it in several different browsers just to be sure. Anyone know of a simple fix before I start digging into the code?

Awesome....exactly what I was looking for.

I have an intranet site, and all i did was dumped the files that I downloaded into a folder in the intranet site.  Is that sufficient?

I get this error:

Parser Error Message: The file '/Intranet/album.ashx' does not exist.

Although the file is obviously there.  Is there something i have to do with the dll?

thank you.

Hi, sorry for my ignorance on this subject, but do I need to configure it as a web application on the web.config file?  I have created a application pool called "photoalbum" in IIS 6, although Im not sure its necessary.

If this is to be done on the web.config file, where on the file do I configure it?  thank you so much for everything!

Thanks for everything, i figured it out.  It was not hard at all actually.  I placed the dll in the bin folder and make sure of the path of the ashx file on the default.aspx file, and viola!  thanks for everythign all, this is awesome!

Sorry for being such a nusance, but how do I control it so that when you go to for example: album/default.aspx, the folder view only shows folders inside of the album folder, and not the folders of the entire web directory?

Right now, the bin folder is in the intranet/bin folder so everything under intranet is being shown in the folder view. Thank you so much.

I am very excited to find this program and it does exactly what I need to show photos of our work to customers (and especially potential customers!). My only problem is that it is displaying all of our directories (ie Admin, Secured, etc) on the main page. How can I restrict it to only look for pics in specific folders such as "WorkPics"? I wish I knew as much as you guys!

A quick question:

I want to have some one click on a link that will take them to one of the folders in the album, is there a way to reference it?  Through a href like ...default.aspx?folder="vacationfolders"

Thank you, and sorry if these questions are juvenile, I am very new to this.

thx again.

Thanks for the reply, but where can i get the url of the specific folder?

right now I have the link set to:

intranet/album/default.aspx?"albummode=preview&albumpath=vacation"

This is the right syntax?

vacation is the name of the folder.

I cannot get this to work, please help!  =(

thanks again, I hate to be pestering you with stupid questions, but how do you use the permalink property to give me the right url?  =(

I guess this will help many other novices as well.

IM sorry, i am about to give up.  Where in this area do I set it?

<body>

   <form id="form1" runat="server">

       <photo:album runat="server" ID="Album1" />

   </form>

</body>

I am able to run the .ashx fine, but when I try to run the template page it gives me the Image-not-found signs where the photos should be. Once you navigate to the actual photos to enlarge them they appear ok. suggestions? I moved the .ashx to the /images directory but left all the other files in the main directory.

Thanks for all your help.

One more question. =)

What part of the code would you have to change in order to make it so that if you click on the thumbnail, a new window pops up with the photo?

Thank you so much in advance, this is an awesome tool.

Thanks Betrand Le Roy:

This is what I have:

writer.RenderBeginTag(HtmlTextWriterTag.A);

writer.AddAttribute(HtmlTextWriterAttribute.Target, "_blank", true);

The second line should create a new window when the user clicks on the thumbnail, no?  I saved the ashx file and it still showing in the same window. Anything I am doing wrong?

Thank you so much!

Worked Perfectly!  THanks alot!  Our entire office is going to love this, I'll make sure the wonderful person(s) behind this awesome program be known.

I'm having the same problem as madtown.  I put the ashx file in the folder with the images i want to display and i have changed the handler's configuration from disk to memory and none.  It still doesn't show the pictures until i click the last one.

Otherwise this is a really cool program.  Thanks :)

Actually I just figured it out.  Thanks for the quick response. It looks great!!

Hi all, anyone know a way to skip the preview and go to the full resolution when cliking on the thumbnail and also to a new window?

thanks!

Hi. This Photo Handler really rocks. Thanks for providing it.

I see it is already mentioned in the comment from Anke. When I run my project on my localhost everything works very fine, but as soon as I try to Build --> Publish Web Site, then I get an error

"There is no build provider registered for the extension '.ashx'. You can register one in the <compilation><buildProviders> section in machine.config or web.config. Make sure is has a BuildProviderAppliesToAttribute attribute which includes the value 'Web' or 'All'."

I'm using VS2008 Beta - it can off course be something with that. However the project im using is in 2.0 not 3.5

I have tried to add a buildProvider as explained, but I cannot see how I can add the attribute that is mentioned.

Did you manage to find a solution with Anke or did you stop researching. Thanks in advance

Regards

Darksaint

Bertrand: Yes the IIS application is configured for 2.0 - it's on windows vista - so it's IIS 7.0 but I don't think that should be an issue.

It's pretty strange as soon as I exclude the ashx file from the project then I can publish/compile the projet but when I include it and try again - then I get the error message that i mentioned before, incredible frustrating *hehe*

Bertrand: Yes it makes sense - actually i did just leave out the page that uses the ashx file when I compile and then I manually upload the page afterwards - that works - I was just puzzeled about the error message and it could be there was some nifty solution to that. Anyways thanks for good support and a kickass handler :)

hi, its a great tool!! But could you please suggest way to add text/caption to the pictues?

Secondly, can we add a fileUpload control there to upload the pictues on the default.aspx?

Thanks,

Chetana

Subject is sort of self explanitory.  I got this to work no problem locally in VS.NET 2005.  Put everything up on my hosted site (DiscountASP.net hosting) and get no images.  No error messages - just no images.

Tried it with all 3 flavors of caching.  No change.  I verified that I'm running framework 2.0.

Not sure where to look next....

Doh! Yes, a handler makes it work much better...

Doesn't seem to matter what I set for path though, I end up getting a server error:

Value cannot be null.

Parameter name: value

Line 1563: if (path != _requestDir && !path.StartsWith(_requestPathPrefix)) {

If I leave it blank I get images for everything except the folder navigation

Mostly working at this point.  Thanks for all the speedy replies!

Two things, I still can't get the path paramter working.  Do you have an example for the syntax for this bugger?

Also, should this work for photos stored in a virtual directory?  Ultimately I'd love to just point the web server at a NAS device with the photo content.

Not 100% sure is I need to change the path or not.  I need to keep the album.ashx file somewhere other than where the pics are.

This is part of the strategy to use a network share to house the images.  I'll have read only access to the image share, and no ability to execute code that resides there.

The album.ashx file will need to live in a physical folder on my web server, and the photo store will be a virtual directory as a sub folder of this real folder.

Either way, the album.ashx code doesn't see to recognize a UNC connected virtual directory.  I'll list it on Codeplex.

Just to inform you of issues in the MetaData library:

I could see every image album folder in the initial page, but when I click an album image, nothing would happen.

I found that the metadata library was unable to open my images and thus 'freeze' your application. My images are shot with a Canon 350D and Canon 40D; the MetaData library with your application is outdated (2.2.2, current version: 2.3.0g) and unable to open these photos.

As someone else already pointed out, replacing the outdated library with the newest will result in .NET binding errors.

When I disabled the Metadata parts in the ASHX, I was able to browse the directories successfully.

Hello,

i'm tryng to change the color from the thumbnails to white and i cant find where do i chenge!

ive change this part and works only for the preview images not for thumbnails (next and preview images):

       private static readonly Color BackGround = Color.White;

thanks for the help!

Hi, This has been working great, but all of a sudden we get this message:

javascript:WebForm_DoCallback('Album1','p/jacksonhole/IMG_0210%20(f).jpg',photoAlbumCallback,'Album1',null,false)

after clicking on an image.

I set it a long time ago to open up in a new window with this line:

writer.AddAttribute(HtmlTextWriterAttribute.Target, "_bank", true);

In the image loop in the gerneratefolder method.

Any ideas why all of a sudden, with no changes, this will happen?

thank you!

Oh i am sorry, the message I get is Page cannot be found.

Javascript is not disabled, i reloaded the file, and it works but as soon as i add the extra line, i get that error.  I get this message on the new window as soon as I click on an image, the line I added opens up a new window which displays the page cannot be loaded.

its the generic "Windows cannot display the webpage" message.

Does this have anything to do with permissions on the picture folders?  I change permissions on the folders where we put in the pictures so others can have access to delete and add pictures.  

Thank you

Hello,

I am trying to load this gallery on my site ( I think it looks great, and can run it locally - but once I drop it in to a test folder on my server (Windows 2003, it's a dedicated and I have it set up with 2.0) I get the following error that I am hoping you can shed some light on:

Line 1:  <%@ Page Language="C#" %>

Line 2:  <%@ Register Src="~/album.ashx" TagPrefix="photo" TagName="album" %>

Line 3:  

Line 4:  <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "www.w3.org/.../xhtml1-transitional.dtd">

Source File: /test/default.aspx    Line: 2

I placed the template of my site on the .aspx files and changed the name of the Album.css to style.css - also adding the necessary info to the style sheet to make it flow along with my site.  I don't see how this would have caused a problem for me.....I'm thinking it is something else.  Help, I would love to use this template!

Hi, I downloaded the files from codeplex. I have VS 2005 installed. What I should do? What steps I need to follow?

I have album.ashx file

Then Samples directory contains

Default.aspx

Templated.aspx

and Album.css

Where should I copy these files?

What file I shoud open in VS 2005? Is their any project?

How do i assign the directory in which the images are placed?

Can some one help me? I will create a Video movie and upload in Youtume or any other location for the benefit of others.

Thanks

When was this version last updated ?, is it possible to list the picture in the order in which they were taken rather than there file date ?

Create tool btw

Is possible to change the backcolor to a thumb image?

I'll try to insert the propose fix but doesn't resolve the problem!

Thanks

Dropping the album.aspx into the directory with pictures isn't working for me.  The only way it is working is to have it in the top level directory. Since I don't own the hosting provide, is there something I should tell them?  I was able to use the 1.0 version is a subdirectory, but not the 2.0 version.  Or is there a way to hard code the path to the subdirectory?

Yes, I meant album.ashx.  Sorry.  I have the Bin directory and dll in the top level app directory.  It all works when the album.ashx is in the top level directory, but when I try moving album.ashx to a subdirectory, the page that references album.asxh gets an error. I've updated the @register line to reference the subdirectory where I've moved album.ashx.  Is this a permission problem or do you have any other thoughts? Thanks.

I just wanted to add that since you allowed for special characters, I assume that you allowed for space as well. I didn't have but three different directories of images to use. The other two directories would display an the thumbnail collection without any problem. But, the filenames in these two directories did not contain any spaces in the filename. The file name in the error had spaces in it, which lead me to assume that spaces was the problem. But I don't know enough about the code to understand what is going on. This particular file mentioned in the error is the last file in the directory. I regret jumping to a conclusion based on my limited knowledge, if indeed my first assumption is incorrect.

Thank you

I've successfully migrated the code to use the newest MetaDataExtractor.dll (V2.4.0b)

Are you intersted in the (minor) changes?

Thanks for your works! It's wonderful!
