I need to copy the currently selected text from the currently active window in the currently active app. If the app support guiInfo.hwndCaret, then I use this. However, in some cases, the app does not support guiInfo.hwnd_Caret, and I have to fall back to plain copying to clipboard to get the currently selected text.

I am checking the WM_CLIPBOARDUPDATE message to see when the content of the clipboard has changed.

However, when nothing is selected in the current active window, this message is not called because the clipboard has not changed.

How would I know that the Ctrl + C has been processed anyways?

Thank you!
