VBS加载webview2控件代替ie的webbrowser(Edge-Chromium谷歌内核)

Maybe I should start with the good news, that all the libraries which are used and available in this toolset, allow you also commercial usage (without opening-up your Application-Code under one of the OpenSource-licenses ... VB-Classic does not offer any static linking) - but that is of course not saying, that "we" (as the VB-community) should not "give back" something under one of these licenses too - your choice of course... :-) So, I will go this route in the next months at least - by opening up the sources of the ActiveX- (COM-) Dll RC6.dll to the VB6-community under LGPL, to offer a "larger security", for those who make use of these wrapper-libs already in their projects - (since "closed source One-Man-shows" are always considered a little bit risky in the long run) - but also to "give something back" into the general OpenSource-community, since without their generousity and efforts something like this "free usable package" here would not be possible at all. Ok, what now follows is a short description of the contents of the build OpenSource-based library: cairo_sqlite.dll which does the underlying "basic-work" here in this small framework ... The ActiveX-Dll: RC6.dll is a ActiveX- (or COM-) wrapper "on top", which allows to deal with the functionality of the OpenSource-libs in a comfortable, objectoriented and secure (VB-)way (secure here means, that you will not need to take care with regards to handle- and/or memory-freeing yourself. But I digress... The opensource-libs were build and linked from C-Source with VS-2019, the MS-runtime-lib is statically linked-in + any suitable speed-optimization was applied, therefore its somewhat larger size, compared with MingW-builds... So, whilst this file describes, what's in cairo_sqlite.dll, the optional \WebKitCairo\-SubFolder contains an additional file like this one here, to describe the contents, libs and licenses for all the WebKit-binaries... -------- please place at least the following license-info in a file -------- -------- (license.txt) beside the RC6-libs in your own deployments -------- The sqlite3-engine cairo_sqlite contains, is public domain due to the generous D.R. Hipp (www.sqlite.org)- but the DB- functionality also contains some differently licensed sub-parts as are: - SQLiteMultipleCiphers (several ways, to support DB-encryption) https://github.com/utelle/SQLite3MultipleCiphers MIT-license - FastLZ (compression-algos, included as Source-Modules) http://www.fastlz.org/ MIT-license - LZ4 (compression-algos, included as Source-Modules) https://github.com/lz4/lz4 BSD-license - ZLib (higher compression, well-balanced compr./decomp. Speed) https://zlib.net/zlib_license.html ZLib-license (very liberal too) - LZMA (highest compression, decomp. fast, compr. slow) http://www.7-zip.org/sdk.html Public Domain license All of the different compression-algos are available over cCrypt of the RC6.dll - and come internally into play for example, when transferring serialized SQLite-Recordsets over TCP/IP (using the RPC-Server-Classes of RC6). Ok, and here the "more cairo-related" Sub-Libs and their licenses: The "main-parts" come of course from the cairo-project, which is licensed under LGPL/MPL: (http://cairographics.org/) - libpixman (fast, optimized pixel-surface-routines) BSD-like license, e.g. mentioned here: http://wiki.mozilla.org/License_Policy - libPng http://www.libpng.org/pub/png/src/libpng-LICENSE.txt PNG-license - ZLib (again, but used here mainly by libPng in CDecl-fashion) http://www.gzip.org/zlib/zlib_license.html ZLib-license - chipmunk (2D-physics engine) http://howlingmoonsoftware.com/chipmunk.php MIT-license - libjpeg-turbo (superfast JPG De- and Encoding) https://github.com/libjpeg-turbo/libjpeg-turbo/blob/master/LICENSE.md BSD-style, combining IJG-, modified (3-clause) BSD- and ZLib-license) - libqrencode (the "quasi-standard" by Kentaro Fukuchi) http://fukuchi.org/works/qrencode/ LGPL 2.1 license (https://www.gnu.org/licenses/lgpl-2.1.html) - quirc-library (small and efficient QR-Decoding by Daniel Beer) https://github.com/dlbeer/quirc It's a "personalized license" which comes below: Copyright (C) 2010-2012 Daniel Beer <dlbeer@gmail.com> Permission to use, copy, modify, and/or distribute this software for any purpose with or without fee is hereby granted, provided that the above copyright notice and this permission notice appear in all copies.

So, please make sure, you include at least this file here along with the RC6-binaries, when you plan to deploy your solutions in a "correct way". And maybe an additional note about using the wrappers new SVG-functionality, which was implemented directly in RC6.dll in plain VB6-code, so - the usual (and somewhat large with all its additional dependencies) librsvg was not needed and linked in the cairo-C-build). The new cairo-tutorial "RC5cairoTutorial.zip", downloadable from here: www.datenhaus.de/Downloads/RC5cairoTutorial.zip ...now contains a few SVG-Icons from the modern (and huge) Oxygen- Iconset - I've already placed a License-Info for these Images in the Demo-Zip-package, but at this occassion let me write something here too, since we are at it. This will get perhaps a bit longwinded, and some parts are repeated (from different angles) more than once, but please make your way through it anyways, I know that the VB6-community is generally "not that fluent" with all the OpenSource-licenses and the implications (I know, I was not ... 3 years ago or so). The Oxygen-IconTheme is now under LGPL too: http://www.oxygen-icons.org/?page_id=4 Which means, that you can use this nice artwork now also commercially in your VB-Apps (rendered over the wrapper) - but take care, that you do *not* link any Oxygen-Icon-resources (no matter if as *.svg, *.svgz or as a "derived" *.png) as resource-file-content directly into your VB-Apps binaries (in case you don't want to open the sources of your Main-Project under LGPL too). You may link them as resource into a VB-dll-binary - but *only* if you open up the sources for this "Icon-resource.dll" under LGPL too (Your Main.exe will not need to be opened then, since it links to your Icon-resource.dll only dynamically). So the background is, that the LGPL forbids any *static* linking - any part which comes under LGPL (be it a C-compiled static library, or an icon), may not be "hidden within" (or merged into) your own (non-LGPL) Project-Sources or the resulting Binaries. So, to be on the safe side with Binaries under LGPL, this usually means dynamic linking against them (which e.g. RC6.dll does per
