Retrieving the window handle of a window a control resides in

For example, let's say i want to get the HWND of the window that IDC_MYEDITCONTROL is located, how would i go about doing that?

Thanks.

If you know the ID and the parent window handle of the child, you can get its window handle like so:

Code:

---

hwndChild = GetDlgItem (hwndParent, idChild);

---

...or, do you mean you want to find the parent window handle of the child window?

Yup, that's what i'm looking for, with just the resource ID. Something like:

Code:

---

HWND parentHwnd = GetParentHWND(IDC_EDITCONTROL);

---

Try GetWindowLong() using GWL_HWNDPARENT, you'll still need the handle of the control though, see Jason's post.

To get the handle of the control, you need the handle of the parent. Heh. :) So, I guess you are going to have to store one or the other.

Jason:

If he knows the title of the parent window, he could use FindWindow(NULL, Title); to get it's handle. I guess like you, I'm a little mystified as to why he hasn't got/had this info. anyway.

that's strange. GetParent() requires the hwnd. You can't just use a control ID to get a parent.

I would assume that is because there can be more than one control with the same id (each for different windows, of course).
