64-bit Preview

[admin]

FYI: The little .NET detour should be good for something, so I thought I try to write Preview64.exe in .NET now and see if I can cross the bitness boundary by remote controlling a container within XYplorer. Worth a try...

Worth a try...

Definitely.

Maybe some other interesting/feasible opportunities/ideas will arise thereby.

Hello I am also a programmer for about 20 programs in Delphi and luckily Delphi even though it doesn't have a large community in the world has always been a tool that has evolved a lot, and today it is copying to various platforms such as Linux, MacOs, Android and everything in 32 Bits and 64 Bits, but I see this with a luck that I had to choose from Delphi, but the big problem of copiling on various platforms is that today Delphi is big and heavy, in order to run it I had to buy a Notebook with Core I9 processor + 32 GB of RAM with a 1 TB SSD because my old notebook could not cope with it anymore and was going to have a coffee, now after I buy this new machine things will work out perfectly.

Now one thing I see is that programs always tend to be born small and over time they evolve, never expect them to be big and powerful at the beginning.

Yep, eternal growth and complication also characterizes the evolution of global tech-culture. New features beat questions of maintencance and sustainability. Ultimately humanity will not die from a war but from a bug.

Looking good! The cross-bitness injection seems to work. It will take some more days but it looks like we'll have 64-bit previews for stuff that needs preview handlers (like Office files)...

[admin]

Here is some proof of concept stuff.

The appended file, Preview64.exe, is a 64-bit .NET executable written in C#. If you place it where XYplorer.exe is, and then preview an Office file (or a PDF, or also some audio and movie formats), then this file should handle the preview and inject it into XYplorer's preview area. A window (owned by Preview64.exe) will pop up where you can (and should!) close the preview to exit it with good manners.

It appears to work here, but who knows. DOCX previews work pretty well, whereas PDF previews lack the scrollbars ( sigh).

[admin]

UPDATE: scrollbars issue will be fixed in next version.

So, does any of you get a 64-bit preview for Office files now?

Works fine here. Office 2019 x64 tested with doc, docx, xls, xlsx, ppt and pptx.

It doesn't process .eml, right?

[admin]

Same here. EML does not seem to have a previewhandler on my system.

It does: CLSID_PreviewMime | Microsoft Internet Messaging API Resources | {92dbad9f-5025-49b0-9078-2d78f935e341}

If you enable it via the registry (e.g. https://www.winhelponline.com/blog/eml- ... r-windows/)
Windows Explorer does preview .eml messages in its preview pane

Nice, it works.

I made it so that it now even works in XY without that reg edit.

But please remove the window with the close button with the next release. Highly annoying and whoever uses this preview should know what he's doing...

[admin]

In this phase the close button is necessary to unload it without memory leaks.

ofc, the button will disappear soon. I just need to implement the interprocess communication, then everything will be smooth and automatic.

Here is the new Preview64.exe with EML power:

Works fine (both of them, the simple text and the office one)^^
