The FlexSim block when i call a remote server interface by dll functon

[yexioamu]

[ FlexSim 21.2.4 ]

I create a dll function that implement the winHTTP, because my flexsim is 21.2.4 which can't modify the HTTP headers.

When I call a remote server interface by this dll, it can work, but the flexsim will block a few seconds，then recieve the response from the remote server. I search this question in this forum, i read this one( Is FlexSim thread safe?), but i can't run this module.

Could i run a separate thread to prevent the flexsim block？

The approach shown in the question you linked to is the right approach. You can launch a thread, and then from that thread, use PostMessage to call a function on the main thread.

WinHTTP also has an asynchronous mode configured with a flag (WINHTTP_FLAG_ASYNC - WinHttpOpen function) and callback (WinHttpSetStatusCallback function).
