Hi David,

I (for one) am VERY excited by this, so thanks for working on it.  A few questions:

1) Will everything that you are working on function with Studio 6 as well?  (I assume so but still want to check)

2) Any chance that you or someone else can do a session on this at EurOmnis?

>Differences between this project directory and Florian's github version:

>- Added /Zc:wchar_t- build setting (Treat wchar_t as built-in type: No --
>Studio 5 externals always need this AFAIK)
>- Added /Zc:forScope- build setting (Force Conformance In For Loop
>Scope: No -- Studio 5 externals always need this AFAIK)
>- Copied some functions from my OmnisTools helpers (
>dmckeone/NVObjTemplate) to assist with string handling
>- Consolidation of some string handling to make it easier to have a
>single non-unicode/unicode code base.
>- Change "logToTrace" to use regular C-strings instead of the Omnis
>str255 type, and convert C-Strings to str255 only when calling
>ECOaddTraceLine (easier Studio 4/5+ compatibility)
>- Add 'object->shutDownWebView()' on line 475 of weblib.cpp to prevent a
>crash when closing the browser window on Studio 5.
>- (Personal Preference) Change 'Output Directory' for Debug builds to: C:
>\TigerLogic\OS523\xcomp  (which is where my current Omnis Studio 5 copy
>is installed) -- Allows me to just push the "Play" button in Visual
>Studio to start debugging.  If you are going to do your own builds,
>you'll likely need to change this setting.
>If you want to install this on your own machine and test it in Omnis
>Studio 5+ (even if you don't have Visual Studio), I've included binary
>xcomps in the package.  To install the xcomps:
>1) Download the project zip file:
>2) Extract the zip file toa  directory.  E.g. C:\omnis-weblib
>3) Open "deploy" folder.  E.g. C:\omnis-weblib\deploy
>4) Install DLLs in your Omnis directory
>   a) Copy "awesomium.dll" from "next_to_omnis_exe" folder to be next to
>"omnis.exe" in the top-level Omnis Studio directory
>   b) Copy "weblib.dll" from "to_xcomp" folder to be in the Omnis Studio
>"xcomp" folder (one level deep from the top-level Omnis Studio directory)
>5) Open (but do not move!) the library "demo5.lbs" in the "lbs" folder. 
>E.g. C:\omnis-weblib\lbs\demo5.lbs
>If you want to move the library to a different directory (or use the
>external in your own application) then you also need to move  the
>'deploy' directory, and you need to change the code in Startup_Task.
>$construct to point to the new location.
>Good luck!
