Hi,
I am having a MFC-based UI app, that I want to initialize and run from a seperate dll, specifically from a Catch2 TEST_CASE.
I tried to export it and also exported theApp, linking statically, dynamically, calling AfxWinInit and wasted many hours with no success.
Errors ranging from pThread is nullptr to m_pszappnam is nullptr and at the end of the day I couldn't even compile it because there were many undefined or double defined references.
What is the correct way to perform:
InitApplication()
InitInstance()
RunInstancer()
from a different dll?
Thanks in advance
Did you also consider starting the existing application (.exe file) using ShellExecute or CreateProcess? You can also pass some arguments.
that would not help me much, since I want to test a PostMessage flow, which I want to initiate and check from the dll
Hi @Günther Humer ,
I suggest you read this issue and refer to the ideas.
This document states
In the body of the function, you may handle any combination of the following scenarios in which the DLL entry point has been called:
A process loads the DLL (DLL_PROCESS_ATTACH).
The current process creates a new thread (DLL_THREAD_ATTACH).
A thread exits normally (DLL_THREAD_DETACH).
A process unloads the DLL (DLL_PROCESS_DETACH).
