Lame question on dialog controls appearance

Ok, I am totally aware this is probably a lame question. The fact is that I have been working on this for so long that I can find an answer anymore. I´m getting (even more) retarded.

My question is simple:
Why can´t an Edit Control created at WM_CREATE using CreateWindowEx and a Edit Control created at a resource file have the exact same appearance? The one created in the resource file has that "3D style" no matter how much I play with it´s styles, I can´t get rid of it and make it "Flat" like the one created at WM_CREATE.
The same thing happens with ListBoxes, and Static controls.
Here´s an example using a listbox:

Code:

---

//This is in my WNDPROC at WM_CREATE:
textdebug = CreateWindowEx (0, TEXT ("listbox"), TEXT("test"),
            WS_CHILD | WS_VISIBLE | WS_BORDER | WS_VSCROLL | LBS_NOINTEGRALHEIGHT | LBS_NOSEL |
            LBS_DISABLENOSCROLL, 15, 252, 333, 104, mainWindow, (HMENU) 1201, hInstance, NULL) ;


//This is in dialogs.rc
ID_STATUSDLG DIALOG DISCARDABLE 1, 12, 237, 223
//EXSTYLE I have tried all possible styles here
STYLE WS_CHILD /*I have tried all possible styles here*/
FONT 1, "MS Sans Serif"                             
BEGIN
LISTBOX "test", IDC_TEXTDEBUG, 5, 141, 223, 64, WS_CHILD | WS_VISIBLE | WS_BORDER | WS_VSCROLL |
LBS_NOINTEGRALHEIGHT | LBS_NOSEL | LBS_DISABLENOSCROLL
END

If you add this example above to a sample program you´ll see what I am talking about. Besides the normal difference in metrics, there´s that 3D border around the control created into the resource file. I need to get rid of that.
Any help will be great, thanks :)

You'd probably need to get rid of the WS_EX_CLIENTEDGE style that is applied to the control by the system. You can do this by doing this in the dialog's WM_INITDIALOG:-

Code:

---

DWORD dwExStyles;
HWND hwndEdit;

hwndEdit = GetDlgItem(hDlg, IDC_TEXTDEBUG);
dwExStyles = GetWindowLong(hwndEdit, GWL_EXSTYLE);
SetWindowLong(hwndEdit, GWL_EXSTYLE, dwExStyles ^ WS_EX_CLIENTEDGE);
SetWindowPos(hwndEdit, NULL, 0, 0, 0, 0, SWP_NOACTIVATE
 | SWP_NOMOVE | SWP_NOSIZE | SWP_NOZORDER | SWP_FRAMECHANGED);

---

Thank you :) Do you believe there´s some way for me to take that style away from all my dlg controls without having to intercept each of them at wm_initdialog like you described?
