Work in progress / USB microscope

This device didn't have any software with it's package, nor links for them.

Windows 7 DirectX can show this device, but i can't find an old  WebCAM code right now.

That device works in Windows 1x, but those apps aren't so good.

That device isn't allowed use by children under 8 years.

Perhaps more to come later.

It works perfectly in Win 7 PRO.  Pro versions contain more intrinsic features than
other versions.  I still get security updates for Win 7 PRO too.

What version is that a schannel.dll and is in register TLS 1.3 ?

I have dll 6.1.7601.24545 2020-01-03, that support TLS 1.2

Thanks for the link Timo!

Attached is the 64-bit version.

I can test on Win 7 PRO, but I need to know a location and file to try to download ....

You would probably have to install some hotfixes on Windows 7 and do some registry tweakings. Better is WinHTTP.

ChatGPT suggests :

You must install these (even if Win7 is "fully patched"):

Update   Purpose
KB3140245   Adds TLS 1.1 / 1.2 support to WinINet
KB3055973   SChannel improvements

Windows 7 WinInet just don't support latest TLS version.

Hi Timo,

Probably, I need to rewrite the application employing WinInet functions.

User contributions / Re: Simple resizer Library

Last post by John Z - December 16, 2025, 03:02:12 PM

Resizer 1.2.0.1
Implemented DeferWindowPos for improved display smoothness
Implemented ASPECT_LOCK which when TRUE will maintain the W to H ratio
of the Dialog when resizing.  When active, resizing is accomplished by
dragging the top or bottom edge which will then automatically adjust
the Dialog width.  Not perfect but works - a notable issue is the mouse
position can appear to the right of the Dialog - off of the Dialog
Implemented MAX_FONT_SIZE to limit font growth when AUTO_SIZE is used if desired

Improved the Form_resize code to minimize time spent.

Still some glitching when LIMIT_SHRINK active and user tries to drag
smaller -

-------------
Zsizer_Demo -
Added menu selection for Options testing to simplify testing, but still
need to modify zsizerlib.h manually for testing optional overrides -

-------------
Resizer distributed with the PellesC package can't be built with the ppj files provided. Looks like a custom installation Pelle uses for development.  So attached is the same resizer with common paths and ppj's for building it yourself. No code change of course.
-------------
Files attached contain code, exe's, and .lib's
