Application Error message box

[mfm]

Hi guys,
At the moment I'm trying to edit my project, after checking the whole thing alright... it can be compiled and built, even there is no problem when I execute the program, however, when I close the application file (*.exe), an 'Application Error' message box appeared and I don't know how to debug it. This is because it shows the access vioaltion from the supported MFC file (...\MFC\SRC\Bartool.cpp)

CToolBar::~CToolBar()
{
AfxDeleteObject((HGDIOBJ*)&m_hbmImageWell);
delete m_pStringMap; //<-this is marked with prob.

m_nCount = 0;
}

I dont think it comes from the CTooolbar variable in my project cos it nothing to do with it, it could be others, what do you reckon?
I tried to use call stack to debug upwards, but I have no idea where to find the bugs...

errgghh.. any idea guys???
thx a lot

Do you delete your CToolBar object? It looks like the destructor is trying to delete some memory, and maybe you already deleted it or overwrote that memory and now it cant. I think it can't find that variable to delete, either because you already deleted it or overwrote it.

tchouch gave me a bunch of things to look for as far as deleting varibale, you can read his stuff at the end of this post:
