Assigning Buddy window to Spin Control - ResEdit (C++)

How do I assign a buddy window to the Spin Control using ResEdit ? (C++) Also, how do I find out what messages the control sends when the up and down arrows (on the control) are pressed. ResEdit Code:

HINSTANCE hInst = GetModuleHandle(0);
WNDCLASSEX wcex;

wcex.style          = CS_HREDRAW | CS_VREDRAW;
wcex.lpfnWndProc    = DefWindowProc;
wcex.hInstance      = hInst;
wcex.hIcon          = LoadIcon(0, (LPCTSTR)IDI_APPLICATION);
wcex.hCursor        = LoadCursor(NULL, IDC_ARROW);
wcex.lpszClassName  = "WndClass0";

SendMessage(hCtrl0_1, WM_SETFONT, (WPARAM), FALSE);
HWND hCtrl0_2 = CreateWindowEx(0, WC_BUTTON, ("OK"), WS_VISIBLE | WS_CHILD | WS_TABSTOP | BS_NOTIFY, 22, 178, 50, 26, hwnd, (HMENU)IDC_OK, hInst, 0);
SendMessage(hCtrl0_2, WM_SETFONT, (WPARAM), FALSE);
HWND hCtrl0_3 = CreateWindowEx(0, WC_BUTTON, ("Reset"), WS_VISIBLE | WS_CHILD | WS_TABSTOP, 100, 178, 78, 26, hwnd, (HMENU)IDC_CANCE, hInst, 0);
SendMessage(hCtrl0_3, WM_SETFONT, (WPARAM), FALSE);

The documentation for the spin control is here. To assign the buddy, you can use UDM_SETBUDDY:

SendMessage( hwndSpinControl, UDM_SETBUDDY, hwndBuddyControl, NULL );

You will not notified of value changes by the UDN_DELTAPOS notification.

You're using ResEdit already, why dont you just use the built-in auto-buddy property in the properties window?

Set value of the Spin Control field "Insert after" next to the Text Edit's one. Select value for "Aligment" (e.g. UDS_ALIGNRIGHT style flag). You can also set true value for "Auto buddy" (UDS_AUTOBUDDY style flag). Spin Control sends WM_VSCROLL message with his own ID.
