GetClipboardData (CF_UNICODETEXT);

Please tell me why I get the following problems:

  • If the clipboard contains unicode characters (eq russian), I get only the first selected word. The first word before the space character.

  • If the clipboard does not contain Unicode characters (English only), I get the first character of the selected text.

Get selected text:

CStringA getClipboard()
{
     CStringA strData;

     if (OpenClipboard(NULL)){

         HANDLE hClipboardData = GetClipboardData(CF_UNICODETEXT);
         char *pchData = (char*)GlobalLock(hClipboardData);
         strData = pchData;
         GlobalUnlock(hClipboardData);
         CloseClipboard();

    }
    return strData;
}

Set Text:

bool setClipboard(CStringA textToclipboard)
{
    bool success = true;

    if (OpenClipboard(NULL)){

        EmptyClipboard();
        HGLOBAL hClipboardData;
        size_t size = (textToclipboard.GetLength()+1) * sizeof(TCHAR);
        hClipboardData = GlobalAlloc(NULL, size);
        TCHAR* pchData = (TCHAR*)GlobalLock(hClipboardData);
        memcpy(pchData, LPCTSTR(textToclipboard.GetString()), size);
        SetClipboardData(CF_UNICODETEXT, hClipboardData);
        GlobalUnlock(hClipboardData);
        CloseClipboard();
    }

    return success;

}

Just install and install the contents of the clipboard.

CStringA str = getClipboard();
setClipboard(str);
