Win32 - Subclassing Rich Edit - c++

Question

I'm trying to create a Windows desktop app which has a Rich Edit control, and I want to handle certain keystrokes within the control e.g. hitting enter will execute some code based on what's been typed on that line, similar to a console app. I started with the regular Windows Desktop App template in Visual Studio, and created my control within the WndProc:
case WM_CREATE:
{
LoadLibrary(TEXT("Msftedit.dll"));
//Console creation
hwndEdit = CreateWindowEx(
WS_EX_CLIENTEDGE, // extended styles
MSFTEDIT_CLASS, // Predefined class
NULL, // text
WS_TABSTOP | WS_CHILD | WS_VISIBLE | WS_VSCROLL |
ES_LEFT | ES_MULTILINE | ES_AUTOVSCROLL, // Styles
0, // x position - size and position handled separately
0, // y position
0, // Button width
0, // Button height
hWnd, // Parent window
(HMENU)ID_CONSOLE, // Control ID
(HINSTANCE)GetWindowLongPtr(hWnd, GWLP_HINSTANCE),
NULL); // Pointer not needed
}
break;
So far, so good. However, when I try to create a procedure for the control and attach it, it doesn't seem to do anything and to be honest, based on the documentation and a lot of Google searches, I'm still not entirely sure how it should be done. My procedure looks like the below:
LRESULT CALLBACK EditControlProc(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam, UINT_PTR uIdSubclass, DWORD_PTR dwRefData)
{
//static HWND hwndEdit;
switch (uMsg)
{
case WM_PAINT:
return TRUE;
// Other cases...
case WM_KEYDOWN:
switch (wParam)
{
case VK_RETURN:
MessageBox(NULL, L"You pressed enter!", L"Title", NULL);
}
/*case WM_CREATE:
{
HWND console = GetDlgItem(hWnd, ID_CONSOLE);
SetWindowSubclass(console, EditControlProc, 0, 0);
return TRUE;
}*/
}
return DefSubclassProc(hWnd, uMsg, wParam, lParam);
}
and my attempt to attach that to the control (which I based on the example here) was:
case WM_CREATE:
{
HWND console = GetDlgItem(hWnd, ID_CONSOLE);
SetWindowSubclass(console, EditControlProc, 0, 0);
return TRUE;
}
I tried handling this within various messages (the last of which was WM_CREATE as above - the link shows WM_INITDIALOG but that didn't work) with no success, and to be honest I'm not sure where I should add this in my case.
I know this is a really basic question and I feel like there should be loads of examples to show me how it's done and I might just be making a stupid mistake (far from unheard of in my short programming studentship), but I've been searching for days and haven't found what I'm looking for so would really appreciate a pointer or two.
Thanks!
