How can I offer the same screen capture options?

[ajtruckle]

The sample application has an option to save a screen capture and uses this code:

void FileComponent::SaveScreenshot()
{
    WCHAR defaultName[MAX_PATH] = L"WebView2_Screenshot.png";
    OPENFILENAME openFileName = CreateOpenFileName(defaultName, L"PNG File\0*.png\0");
    if (GetSaveFileName(&openFileName))
    {
        wil::com_ptr<IStream> stream;
        CHECK_FAILURE(SHCreateStreamOnFileEx(
            defaultName, STGM_READWRITE | STGM_CREATE, FILE_ATTRIBUTE_NORMAL, TRUE, nullptr,
            &stream));

        CHECK_FAILURE(m_webView->CapturePreview(
            COREWEBVIEW2_CAPTURE_PREVIEW_IMAGE_FORMAT_PNG, stream.get(),
            Callback<ICoreWebView2CapturePreviewCompletedHandler>(
                [appWindow{m_appWindow}](HRESULT error_code) -> HRESULT {
                    CHECK_FAILURE(error_code);
                    appWindow->AsyncMessageBox(L"Preview Captured", L"Preview Captured");
                    return S_OK;
                })
                .Get()));
    }
}
//! [CapturePreview]

But in Microsoft Edge itself, when using Screenshot, it offers us useful options:

How can I offer the same options?

I simply use the Windows internal tools with the following short keys - Shift + LWin + S

Does the same job as the Screenshot tool Microsoft removed from the WebView2 control!

@PCRacer that is interesting solution. I use the feature but did not think of using it. Is it best to fire it off programmatically from a command line prompt rather than hotkey? What would be?

Shift + LWin + S is shortcut of
ms-screenclip:

Simply simulate the keystrokes programmatically so that it seems to be coming from your app:

#include <windows.h>

int main() {
INPUT inputs[6] = {};

// Press Shift
inputs[0].type = INPUT_KEYBOARD;
inputs[0].ki.wVk = VK_SHIFT;

// Press Windows key
inputs[1].type = INPUT_KEYBOARD;
inputs[1].ki.wVk = VK_LWIN;

// Press 'S'
inputs[2].type = INPUT_KEYBOARD;
inputs[2].ki.wVk = 'S';

// Release 'S'
inputs[3].type = INPUT_KEYBOARD;
inputs[3].ki.wVk = 'S';
inputs[3].ki.dwFlags = KEYEVENTF_KEYUP;

// Release Windows key
inputs[4].type = INPUT_KEYBOARD;
inputs[4].ki.wVk = VK_LWIN;
inputs[4].ki.dwFlags = KEYEVENTF_KEYUP;

// Release Shift
inputs[5].type = INPUT_KEYBOARD;
inputs[5].ki.wVk = VK_SHIFT;
inputs[5].ki.dwFlags = KEYEVENTF_KEYUP;

SendInput(6, inputs, sizeof(INPUT));

return 0;

}

@PCRacer
Using SendInput works cleaning. Thank you.
