C++ 307 Görsel stüdyo 2010'a winhttp.h eklemeye çalışırken hatalar

Question

Büyük bir sorunum var. Ben C++ ile dosya indirmek için WinHttp kullanmaya çalışıyorum ve bunu yapmak için Visual Studio 2010 kullanıyorum.

Sorunum, programın derleme olmadığını, çünkü tümü "winhttp.h" ifadesini kullanan 307 hataları oluşturduğundan kaynaklanıyor. Bu dosyayı eklediğimi belirtiyorum. Sorun ne olabilir? Teşekkürler!

Şimdi ne sorun olabilir? Belirli bir URL'den bir dosya indirmek için bir program parçası yapmak için 2 gün çalışıyorum. Bu beni delirtiyor! Lütfen bana yardım et!

Answer 1

#include <winhttp.h> önce #include <windows.h>'u ekleyin.
