actually i already tried but doesn't override the original function
here's what i tried
Code:
	//hook CloseWnd
	vftableHook(0x00d9e734, 43, addr_from_this(&CIFWnd::OnCloseWnd));
	//placeHook(0x00652c00, addr_from_this(&CIFWnd::OnCloseWnd));
	//replaceAddr(0x00d9e7e0, addr_from_this(&CIFWnd::OnCloseWnd));

You must use different name of the original function (Example : OnCloseWnd_IMPL)

Okay here's what i did according to what you've suggested

Code:
bool CIFWnd::OnCloseWnd() {
    return reinterpret_cast<bool(__thiscall *)(CIFWnd *)>(0x00652c00)(this);
}
Code:
bool CIFWnd::OnCloseWndImpl()
{
	if ( IsSame(GFX_RUNTIME_CLASS( CIFItemMall ) ))
	{
		g_pCGInterface->RenderItemMall(0);
	}
	return CIFWnd::OnCloseWnd();
}
Code:
//Util.cpp
vftableHook(0x00d9e734, 43, addr_from_this(&CIFWnd::OnCloseWndImpl));
but that didn't work either i even used vftableHook on all possible classes that inherit CIFwnd and doesn't override OnCloseWnd like this


so from what i've experienced so far, hooking a virtual method at the parent class is impossible yet!



anyway here's the function body if someone interested

Code:
// CIFWnd::OnCloseWnd(void) .text 00652C00 000000CF 00000004 00000000 R . . . . . .
//HOOK_ORIGINAL_MEMBER(0x00652C00, &CIFWnd::OnCloseWnd);
bool CIFWnd::OnCloseWnd() {
#if 0
    return reinterpret_cast<bool(__thiscall *)(CIFWnd *)>(0x00652c00)(this);
#else
	if(IsKindOf( GFX_RUNTIME_CLASS( CIFStore ) ) && g_pCGInterface->sub_7992E0())
	{
		CGEffSoundBody::get()->PlaySoundA(L"snd_window_close");
		g_pCGInterface->sub_79DBD0(0, 0);
		return false;
	}
	else if (IsSame(GFX_RUNTIME_CLASS( CNIFEnchantWnd )))
	{
		g_pCGInterface->RenderEnchantWnd(0);
	}
	else if ( IsSame(GFX_RUNTIME_CLASS( CIFQuestInfo )))
	{
		g_pCGInterface->RenderQuestInfo(0);
	}
	else if ( IsSame(GFX_RUNTIME_CLASS( CIFNewItemMall ) ))
	{
		g_pCGInterface->RenderNewItemMall(0);
	}
	else
	{
		ShowGWnd(false);
		GetParentControl()->SetFocus_MAYBE();
		g_pCGInterface->FUN_0079a7e0(this);
	}
	return true;
#endif
}

Are you sure about the address and the place of function the Vftable (43)?

well, including those 2 weird locations the offset should be at 43 of the vftbl!

hey reverse engineering mates
on my way down of reversing CIFUnderbar (which was deprecated but not entirly removed from the vsro188 just become an instance to CNIFUnderMenuBar)

I've found some interesting informations that should be 90% correct
  • CGWndBase::IsVisible() should be IsShowGWnd() confirmed @SpecialtyDeal::sub_74F960
  • CGInterface::ToggleMainPopup() should belong to CIFUnderbar according to CIFUnderbar__MESSAGE_MAP, i call it OnMenuBtnClick()
  • CIFUnderBar::Func_28: args are (CIFSlotWithHelp *a1, CIFSlotWithHelp *a2, int a3) mean at the derived classes should be the same type too
  • CGame::GetHWnd @BA3CA0 & CGame::GetMainInstance @BA3CB0: Should belong to CGFXMainFrame
  • CObjChild should contains 3 static members [CObjChild::m_pGInterface(g_pCGInterface), CObjChild::m_pGfxEttManager(g_pGfxEttManager ), CObjChild::m_pGfxDevice]
  • g_pCICPlayer is g_pMyPlayerObj confirmed by asserts in 2 functions

feel free to correct them while i gather more informations
many thanks to @ my reverse engineering leader and @ (his src snippets were so much helpful in labels and data types guessing, wish he shares more in the future)


my last achievements on reversing CIFSlotWithHelp
had tough times on reversing Sort of item though, so i used the old school way of sorting depending on TID3 & TID4

Hello everyone. I built the following code using VS2005. It works well. However, when pressing F5, F6, F7 multiple times, the game may disconnect (it may crash). I think it's due to some issue with wstring. Can you let me know how to fix it? Thank you!

This opened the way for many who wanted to improve themselves; Floria took a step on this path.
