好吧,這是一個相當複雜的問題,但它看起來像autoit IE.au3項目已經完成了艱苦的工作。所以現在只需要有人熟練使用ruby和win32api,並且可能還需要自動學習如何將使用IE.au3編寫的函數轉換爲ruby。最終的結果是我想用嵌入式IE瀏覽器(IE嵌入在另一個應用程序中)使用Watir。我已經測試過,autoit函數對我正在使用的應用程序正常工作,但是我更喜歡使用watir(這是ruby)而不是autoit來測試html。使用ruby獲取嵌入式IE瀏覽器的COM對象win32api
我可以得到嵌入式瀏覽器的hwnd沒有問題(通過與autoit接口和使用自動化ControlGetHandle函數 - 注意到我無法與IE.au3接口,因爲它沒有內置到自動DLL,它的用戶定義函數庫 - UDF)。下面是我需要翻譯的功能(我還包括這個函數調用的另外兩個短函數,但我並不真的需要這些,我已經證實了我的翻譯過去)。

這裏是我到目前爲止(其中大部分來自於淨另一個海報誰是試圖解決同樣的問題來了,似乎是在正確的軌道上):
def get_control_from_hwnd(hnd)
Win32API.new("ole32", "CoInitialize", ['P'] , 'I').call(0)
reg_msg = Win32API.new("user32", "RegisterWindowMessage", ['P'] ,'I').call("WM_HTML_GETOBJECT")
puts "msg: " + reg_msg.to_s
result=" "*16
aInt = [0xA7, 0x31, 0x0, 0xA0, 0xC9, 0x8, 0x26, 0x37].pack 'I*'
a = [0x626FC520, 0xA41E, 0x11CF, aInt].pack 'IIIP'
sendMessagetimeout = Win32API.new("user32", "SendMessageTimeout", ['L','I','I','I','I','I','P'] , 'L')
sendMessagetimeout.call(hnd.hex, reg_msg, 0, 0, SMTO_ABORTIFHUNG, 1000, result)
puts "result unpacked: " + result.unpack("L").to_s #i can confirm this is the same as the lResult from the autoit functioin
idisp=0
#the problem is likely either here or the next line afterwards
oIE = Win32API.new("oleacc", "ObjectFromLresult", ['P','P','I','P'] , 'L')
oIE.call(result, a, 0, idisp)
puts "idisp: " + idisp.to_s
# returning zero
puts idisp.unpack("L")
end
好吧我知道這裏的工作比任何人都願意做得更多,但也許如果你看看我的翻譯和原文,有些東西可能會跳出來,因爲你錯了。我肯定會爲任何想出解決方案的人提供賞金
