Details pane is at the bottom, preview pane is placed at the right; see Organize->Layout->Details/Preview/Navigation pane.

Just had a quick look at MSDN and Visual Studio samples. Adding preview pane handler means making a viewer plugin for Explorer, eg. just like Adobe Reader enables reading of pdf files directly inside web browsers.
I was thinking about a viewer as an ActiveX dll or something like that anyway (yea I know, hardcore stuff), so I would probably want to do 2 (or more) birds with one stone. And I can't release a half-product, plus gazillion of other development issues/stuff, all in all... "When it's done".

PS. While I was writing this, a crash error appeared "Preview Handler Surrogate Host has stopped working" (process that actually runs preview). It crashed trying to open preview for saved HTML file. LOL

Everything looks great after all this time I'm using it, no bugs on my DualCore 2Gig PC too (even on large file contents).

Just a question, now that it thumbnails my zips & rars, do I have a way snag the thumbnail for my personal use - like it cache the thumbnails using windows cache, can it be modified to save it in some folder as jpg?

Works perfect on XP here...
Thanks for sharing it!

I would like to show the thumbnails on a GUI...
Thanks!

I installed latest version on windows 7 64x with cdisplay 1.8, but i cant see any thumbnail preview. Is there something I am missing?

How to extract thumbnail in c/c++:

alicialgg · Guest

it worked! I restarted the computer after installing and bum! all my thumbnail appeared!

This is great, Thank you!

Thank you so much for doing this. Can't say thanks enough.
Thank you thank you thank you

.EPub files are e-books which are basically zip files with xhtml and (cover) images. Can CBXShell create thumbnails for those aswell? I could get it to work with cdisplayex but the bugs drove me crazy. and i can't get it to work with CBXShell.

By design, I didn't go for binary file recognition because that can be complicated given that archives can be self-extracting exes, etc.
When I get some spare time maybe I'll add something like user-defined file extensions support.
For the moment, I just added if (StrEqual(szExt, _T(".epub"))) return CBXTYPE_CBZ; at line 542 in cbxArchive.h.
32 & 64-bit dll:
http://www.autohotkey.net/~T800/CBX/cbx4203.zip

If you already used installer (if not, use it first to make this simple), you can replace dll files like this:
1. Extract 32 or 64-bit dll from zip (must match your Windows edition).
2. open command prompt (elevated if Vista/7 under UAC)
3. close all windows and applications, then wait a minute or two so that system releases files in use.
4. type in the command prompt: copy "<path of the new (unzipped) dll>" "<path to the old (installed) dll>" (use quotes if needed)
If all OK it will say that it copied 1 file.

Also, the question is if e-books (*.epub....) fall under this topic, because it seems to me that it should be a project for itself, from my experience cb* files are more similar to archives then are e-books which only use compressed file as a container (wikipedia topic on ebooks talks about html, xml, svg, etc.).

After all, the source code ist fur alle da.

Could you please compile a binary package without SSE2 optimizations?

Ok, here are dlls without SSE
http://www.autohotkey.net/~T800/CBX/cbx4203noSSE.zip

I could use some feedback on this. Do you run some older hardware?
AFAIK, SSE was introduced in Pentium III in 1999, and SSE2 in P4 processors in 2001.
Here are 3 versions of my test app in release compile: no SSE, SSE, SSE2, optimizations set for speed.

Drag and drop files onto dialog to test.
You can tell me how they behave, post messages/screenshots of errors.

Well, Athlon XP processors don't support SSE2. The last batch of them came out about 5 years ago, they were really popular, many people still use them. Then netbooks became popular, most didn't support SSE2, the bottom line is hardly anyone optimizes 32-bit desktop applications for SSE2 even today. And, in general, you get better performance from non-SSE2 32-bit binaries than optimized 64-bit ones (although the difference is negligible of course).

I did try the tests but couldn't notice any difference, mainly because results varied wildly with each use. Can you make the test run multiple (50-100) times automatically?

Thanks for the build Smile

And here's the crash report for CBXTest_SSE2.exe on an Athlon XP

I tried test app with 100 iterations, and there was no real difference (the only reason I enabled SSE in compiler settings was simply because 'it's there, so crank it up').
I recompiled all without SSE, version 4.4, you can download updated package. This should run on any CPU.
