मैं डेमो उद्देश्यों के लिए एक कुंजीपटल के रूप में उपयोग कर रहा हूँ this board में SendInput के माध्यम से कुंजी भेजें।user32.dll
फिर भी लम्बी कहानी कम सब कुछ बहुत कुछ मामलों को छोड़कर ठीक काम करता है बनाने के लिए। मैं SendInput user32.dll में स्थित समारोह के साथ कीस्ट्रोक्स भेजें।
तो मेरी कार्यक्रम लगता है:
static void Main(string[] args)
{
Console.Write("Press enter an on the next secont the key combination shift+end will be send");
Console.Read();
Thread.Sleep(1000);
SendKeyDown(KeyCode.SHIFT);
SendKeyPress(KeyCode.END);
SendKeyUp(KeyCode.SHIFT);
Console.Read();
Console.Read();
}

और यहाँ structs कि मैं ऑनलाइन पाया गया कि उन तरीकों का उपयोग और भी महत्वपूर्ण कोड हैं: (यह कोड का एक बहुत की तरह लग रहा है और है ध्यान दें क्योंकि वहाँ एक Enum में महत्वपूर्ण कोड का एक बहुत)

तो अब मेरे सवाल है कारण है कि जब मैं भेज कि कुंजी संयोजन मैं जब मैं एक असली ke पर कर के रूप में एक ही परिणाम नहीं मिलता है yboard? 98% चीजें काम करते हैं। उदाहरण के लिए मैं ऐसा करने में सक्षम हूँ:
SendKeyDown(KeyCode.SHIFT);
SendKeyPress(KeyCode.KEY_A);
SendKeyUp(KeyCode.SHIFT);
और वह एक राजधानी ए
मैं एक अलग पुस्तकालय का उपयोग करना चाहिए भेज देंगे?
कारण है कि मैं इस दृष्टिकोण की तरह है, क्योंकि मैं पहले से पता नहीं है, तो उपयोगकर्ता विंडोज़ रूपों में उदाहरण के लिए एक कुंजी संयोजन भेज देंगे, तो मुझे क्या करना:
System.Windows.Forms.SendKeys.SendWait("+{end}"); कि shift + अंत भेज देंगे लेकिन शायद उपयोगकर्ता सिर्फ शिफ्ट भेजना चाहता है ...
आप इस धन्यवाद क्या मैं देख रहा था! – hurnhu
