Closing game interfaces with ESC key — UI (inventory, guild, Arena, etc.) 5517v

[Darach]

Hey,

I'm building a DLL overlay for v5517 and trying to make ESC close game interfaces (inventory, guild, status, etc.) — similar to how the v6609 client does it natively.

What works:

ESC closes my own ImGui panels

ESC passes through to the game's native handler — closes warehouse, shops, and other windows that already support ESC

What doesn't work:

Inventory, guild, and other custom-rendered windows don't respond to ESC at all

What I've tried:

• PostMessage(hwnd, WM_CLOSE, 0, 0) on the game windows (codes 153, 137, 233, etc.)
• PostMessage(hwnd, SC_CLOSE, 0, 0)
• EnumChildWindows to find and click small top-right close buttons (simulated WM_LBUTTONDOWN / WM_LBUTTONUP)
• WM_CLOSE on the parent HWND from GetWnd

None of these do anything — the game's UI is custom-rendered on DirectX, not standard Win32 controls. There are no real child close buttons to click.

My question: Is there a known way to close these custom interfaces from the DLL side? For example, is there a game function or flag that the client uses internally when you click the X on those windows? Or is the only option to find and call the same function the game uses?

Thanks in advance.

The solution is simpler than expected: get the HWND via GameGetHWND(dialogCode) (the game function at 0x597FC3 returns a pointer, HWND is at offset +0x20), then just ShowWindow(h, SW_HIDE). That's it — same as what the game does internally to hide them.
