Just wondering...about ID's

I have a handle

Code:

---

HWND hbtnGetHandle; //get the handle

---

and this to create a button:

Code:

---

        hbtnGetHandle = CreateWindowEx(NULL,"BUTTON","Get Handle",
                WS_CHILD | WS_VISIBLE, 7, 7, 90, 20, hwnd,
                NULL, g_hInst, NULL);

---

How do I set it so that in the wndproc, i can use a switch case
and use ID_SOMETHING? Is it in LOWORD(wParam)? if so, how do i set the id to the wParam of the button?

You can't associate an ID with a window unless you create a dialogue-box template in memory, and create from there (painful and not recommended).

In the window procedure, I think it's lParam contains the window handle.

Ok, chief :) so i just use the handle

Yep :) If you use dialogue boxes the ID is passed separately (can't remember so check the docs)
