How can I view this SDL2.dll source?

I want to change some of the code in sdl2.dll. But I don’t know where this source code is. Does anyone know where the monogame dependency library sdl source is?

The official explanation is:

If the application draws the composition window, the default IME window does not have to show its composition window. In this case, the application must clear the ISC_SHOWUICOMPOSITIONWINDOW value from the lParam parameter before passing the message to DefWindowProc or ImmIsUIMessage. To display a certain user interface window, an application should remove the corresponding value so that the IME will not display it.

//    *lParam = 0;
//    break;

The message handling code is here. I assume that’s what you need, not the actual SDL code :slight_smile:
