The C++ equivalent of Delphi’s uses
clause is #include
statements for C++ header file.
In this case, to use TIdHTTP
in C++, you need an #include <IdHTTP.hpp>
statement in your C++ code, and make sure Indy’s header files are in a folder in your project’s Includes search path. If you drop a TIdHTTP
component on a Form/Frame/DataModule at design-time, the IDE will generate the #include
statement for you. Otherwise you have to add it manually.
