How to convert this sh*tcode to C?
« on: November 24, 2023, 06:21:04 PM »
Can anybody tell me, what this code means and how to convert it to pure C? Is this possible?

Code: [Select]
// <-- WebView2 sample code starts here -->
// Step 3 - Create a single WebView within the parent window
// Locate the browser and set up the environment for WebView
CreateCoreWebView2EnvironmentWithOptions(nullptr, nullptr, nullptr,
Callback<ICoreWebView2CreateCoreWebView2EnvironmentCompletedHandler>(
[hWnd](HRESULT result, ICoreWebView2Environment* env) -> HRESULT {

// Create a CoreWebView2Controller and get the associated CoreWebView2 whose parent is the main window hWnd
env->CreateCoreWebView2Controller(hWnd, Callback<ICoreWebView2CreateCoreWebView2ControllerCompletedHandler>(
[hWnd](HRESULT result, ICoreWebView2Controller* controller) -> HRESULT {
if (controller != nullptr) {
webviewController = controller;
webviewController->get_CoreWebView2(&webviewWindow);
}

Not easily, something wrong with that code.
Reformat it better way.
May the source be with you

Thank you TimoVJL!
Why don't they (micro$oft) want , that we to use the C language? First in GDI+, where you can't call them with C. Yes, a visual studio (ms sdk) does not allow use flat Api! You can try it. Only PellesC includes work!

TimoVJL, sorry, but I can't compile your code, in PellesC .

Error in string
Code: [Select]
completedHandler->lpVtbl->AddRef = HandlerAddRef;
 error #2168: Operands of '=' have incompatible types 'unsigned long int __stdcall (*const)(ICoreWebView2CreateCoreWebView2ControllerCompletedHandler (aka struct ICoreWebView2CreateCoreWebView2ControllerCompletedHandler) *)' and 'unsigned long int __stdcall (*)(LPUNKNOWN (aka struct IUnknown *))'.

 error #2033: Assignment to const location.

Hello, Vortex
Rust is more "better"...In future we must convert sources from Rust? No..

I haven't fixed it yet, perhaps frankie can do it. MSC is more flexible with code, so those examples needs fixing.

TimoVJL, but you can compile it in MSVC? I can't . If you can - what version of studio you use?

I agree with you. Rust is just another propaganda.

i couldn't compile it with cl neither. So a bad example from net  >:(

WebView2 needs this too: WebView2Loader.dll

Code: [Select]
LIBRARY WebView2Loader.dll
EXPORTS
_CreateCoreWebView2EnvironmentWithOptions@16 = CreateCoreWebView2EnvironmentWithOptions

dll, include, libs :
https://www.nuget.org/packages/Microsoft.Web.WebView2

Thanks frankie.
Don't work in Windows 7  :(

That was an important line:
Code: [Select]
webviewController->lpVtbl->AddRef(webviewController); // <-- here, increase the reference count for the webviewController
Now i can remove useless code.

WebView2 runtime :
https://developer.microsoft.com/en-us/microsoft-edge/webview2/#download-section

In Windows 7
Code: [Select]
GetProcAddress(0x75090000 [KERNEL32.DLL], "SetThreadDescription") called from "EMBEDDEDBROWSERWEBVIEW.DLL" at address 0x66EC1D51 and returned NULL. Error: The specified procedure could not be found (127).
