CStatic - disable double click copy to clipboard.

[Tony.star21]

Hi all,

by default double-clicking on the label (CStatic) control, you copy the text of the label to the clipboard. To disable this functionality I followed this site. The problem is, that I want to preserve the previous value of the clipboard. Based on MSDN documentation the WM_GETTEXT should return the text length without null character. I do so, but my code still not working, which means that the clipboard is empty.

        LRESULT WindowProc(UINT message, WPARAM wParam, LPARAM lParam) override
        {
            if (message == WM_LBUTTONDBLCLK)
            {
                double_click_flag_ = true;
            }
            if (message == WM_GETTEXT && double_click_flag_ && !double_click_copy_)
            {
                double_click_flag_ = false;

                HANDLE clip = nullptr;
                if (OpenClipboard()) {
                    clip = GetClipboardData(CF_TEXT);
                    CloseClipboard();
                }
                string text;
                text = (char*)clip;
                std::wstring wsTmp(text.begin(), text.end());
                return wsTmp.length();
            }
            return CStatic::WindowProc(message, wParam, lParam);
        }

Any idea?

Thx
