    Debug Assertion Failure

    Hi everybody

    Seems like I made quite a mess here.

    Has anyone ever seen the following message, and can lead me to the possible cause???


    "Debug Assertion Failed.
    File:dbgheap.c
    line 1017

    EXPRESSION- BLOCK_TYPE_IS_VALID(phead->nblockuse)"


    This error occurs while running my project, and I have no clue as to the reason for it

    Please help

    cheers

    Could you post the code that's causing the problem? Usually when I get this problem it's because I didn't allocate enough memory for something and free panics. Like allocating space for a string but forgetting the +1 for the null character.

    Show us the code. But I'm pretty sure that it has something to do with the free function. Some time ago I had the same problem. I didn't allocate enough memory.
    Current projects:
    1) User Interface Development Kit (C++)
    2) HTML SDK (C++)
    3) Classes (C++)
    4) INI Editor (Delphi)
