सी ++ 307 विज़ुअल स्टूडियो 2010 में winhttp.h को शामिल करने का प्रयास करते समय त्रुटियां

Question

मुझे एक बड़ी बड़ी समस्या है। मैं WinHttp का उपयोग C++ के साथ फ़ाइल डाउनलोड करने का प्रयास कर रहा हूं और मैं इस काम को करने के लिए विजुअल स्टूडियो 2010 का उपयोग कर रहा हूं।

मेरी समस्या यह है कि प्रोग्राम संकलित नहीं है क्योंकि 307 त्रुटियां उत्पन्न हुई हैं, सभी winhttp.h पर प्रतिक्रिया दे रही हैं। मैं उल्लेख करता हूं कि मैंने उस फ़ाइल को शामिल किया है। क्या समस्या हो सकती है? धन्यवाद!

अब मैं एक और समस्या है:

वहाँ कुछ कर रहे हैं। यह मेरा कोड है:

क्या अब समस्या हो सकती है? मैं किसी दिए गए यूआरएल से फाइल डाउनलोड करने के लिए कार्यक्रम का एक टुकड़ा बनाने के लिए 2 दिनों का प्रयास कर रहा हूं। यह मुझे पागल कर रहा है! कृपया मेरी मदद करें!

Answer 1

#include <winhttp.h> से पहले #include <windows.h> जोड़ें।
