I was wondering if there was a way to get the top directory links at the top to work with https or a non standard port? If you read this and know of a way can you email me at steve@mcenaney.net?

I have been using the DirectoryListing for quite some time. When I updated to IconHandler 2.0 I lost the folder icons. If I disable useSavedIcons the folder icons work correctly. Any ideas?

Caleb,

You may have found a bug where IconGen.exe doesnt export folder icons. Let me look into it ...

Thanks,

Mike

Hey Mike, I think I found a bug in the dll. When using the saved icons it looks like it is serving up the BMP directly as text/html. Firefox wasn't too happy about that. Thanks, Mike!

I have one error (in spanish) Mensaje de error del analizador: Atributo 'useSavedIcons' no reconocido. Tenga en cuenta que en los nombres de atributo se distinguen mayúsculas y minúsculas. Means: Attribute “useSavedIcons” not recognized

I've been working on the Directory Listing Module for a few hours now. I got the Directory Listing part to work fine in very little time. However, all the icons are showing up as broken JPEGs. When I go to "http://localhost/geticon.axd?file=.ppt" or any variation, I get 404'd. Right now I'm just using the Sample site that you provided. The page formatting is fine, just no icons. Any ideas where I went wrong? Thanks! -Patton

To those who noted that the folder icons do not appear when using DirectoryListing and IconHandler 2.0; if you pregen the icons, you need to rename the Folder_{size}.bmp to simply _{size}.bmp. This work around works quite nicely. If you look at the generated URL, the query parameter for "file" is empty, so I'm assuming this puts an icon with an empty file type. @Mike - Do you ever plan on opening this up on CodePlex or anything? Thanks! -dl

I have the same problem as General Patton04. In firefox it just says the text "icon" without the quotes next to the folder or file instead of showing an actual image. In IE, it looks like a broken image, there's a box with a red X in it and it says icon, then the file or folder name. If I try going to /geticon.axd?file=.pdf or any other file type it says the page cannot be found.

Hey Mike, very good stuff you have created! Were you able to resolve any of the issues in this stream? I have the directorylist working great, but I like the other post have broken image icons for my icons, When I run GETICON.AXD I get teh correct Icon, I have also used the IconGen and put the large icons in the app_resouce folder. Running on IIS6 Server 2003. Thanks again

HttpRuntime.AppDomainAppVirtualPath is not returning the site header. ie http:///geticon.axd?file= the application is returning "/geticon.axd?file=" no host name. is there a specific item I need to enable or allow permissions to read this?

Hi Mike, from a fellow MVP. I'm just now trying your code, and am seeing the same problem that marc described on 3/18/09. Just curious if you have a resolution for this. Thank you...

I've got an odd issue. On the same server I have a functioning 'useSavedIcons' and a non-functioning one. Like others above, the directory listing works on both, however, one the icons fail to load. I've tried overwriting all the core files between the two, permissions, etc. Obviously there has to be something different but I can't determine what. If I try the direct geticon.axd the faulty site returns 404. On the dir listing page source, I noticed that the img tag path is broken. It shows: src="http://mvolo.com/filesgeticon.axd?file=" ... rather than: src="http://mvolo.com/files/geticon.axd?file=" The a href is set OK. I modified the dirlisting.aspx and added the '/' so now the page source shows correctly, but still no icon.

I have an odd problem with icongen.exe and corel draw .cdr extensions. It doesn't read the icon, I just get the generic icon. It creates icons for other formats; i.e. adobe illustrator (.ai),.jpg,.pdf, etc. as expected. I have Corel Draw X5 installed with Windows XP (32 bit). You can download a 30 day demo at corel.com to test. I checked the HKEY_CLASSES_ROOT\.cdr and it has no defaulticon key (either does .ai) but the (default) value is "CorelDraw.Graphic.15" The (default) value for .ai is "Adobe.Illustrator.14" Both of those values have a DefaultIcon key with a path to the executable and an index of 1, i.e. "c:\Program Files\Corel\CorelDRAW Graphics Suite X5\Programs\CORELDRW.EXE,1". Changing the case doesn't matter and I can intentionally add an "X" at the start of the AI entry to make it generate a generic icon intentionally so I seem to be looking in the right place. I can manually extract icons from the corel executable. There are several file types associated with installed apps I still get the generic icons for. Any ideas? Thanks
