HMG with Edge WebView2

[srvet_claudio]

Hi,
After much trial and error, and fight a little with the parameters of hbmk2 I managed to create a demo of HMG with Edge WebView2.
It is not much information on Edge WebView2 compiled with GCC/MinGW on the Internet maybe because most people use Visual Studio to build WebView2 applications. Most of the samples use MSVC ++ and a few of Microsoft's own compiler C++ classes.
I hope you enjoy!

Hi,
1) My .exe not work?

2) Try change this line in C code:

HRESULT result = CreateCoreWebView2EnvironmentWithOptions( nullptr, TStrToWStr(szDataPath).c_str(), nullptr, &handler );

For this line:

HRESULT result = CreateCoreWebView2EnvironmentWithOptions( nullptr, nullptr, nullptr, &handler );

There is not much information on webview2 with c ++ and the error answers are very ambiguous in many cases. Please compile this new file to see if we can better capture the error that occurred.

Hi Andres,
The information on the internet is scarce, but the problem seems to be with the runtime version you have of webview2, please update your runtime version from this Microsoft link:

Hi,
this is a slightly improved version with more information to detect and solve errors in webview2 runtime.
