How to get button IDs created via CreateWindow() WinAPI?

Question

C++ / C#

I create buttons in a vector (because a different number depending on the conditions)

static vector<HWND> hBut;
hBut.push_back((CreateWindow(L"BUTTON", buf, WS_CHILD | WS_VISIBLE | WS_TABSTOP, x, y, nWidth, nHeight, hDlg, NULL, hInst, NULL)));

But I don’t know how to get the ID of all buttons, since they were created not graphically (by transferring) but by code. How to get them?
And since I’m asking a question, then maybe tell me how to do push_back () if I have a vector with a smart pointer:
static vector<std::shared_ptr<HWND>> hBut;

I guess you need GetWindowLong(hButton, GWL_ID), but it can be zero by default. Shared_ptr needs a CWnd wrapper class that will destroy the window in its destructor. If you do not want to use MFC, then write an analogue yourself.
