Hello,

My application is using a Dll loaded with the function
"LoadLibrary(<NameOfTheDll>)"

In the dll there is the following fonction :

char * GetMessageError(int Error)
{

    char * pMessageError;
   
    CString ErrorMessage;

(...)// filling of Error message
   
    pMessageError= new char[ErrorMessage.GetLength()+1];
    strcpy_s(pMessageError,ErrorMessage.GetLength()+1,ErrorMessage.GetBuffer());

    return pMessageError;
}

In my application there is the function :

void DisplayMessageError(int DllError)
{
    char * pMessageError= GetMessageError(DllError);

    if(pMessageError){
       
        AfxMessageBox(pMessageError);
        delete pMessageError;//!!!!!!!!!!!---------->Problem at this line
    }
}

In debug mode when executing the line 'delete pMessageError'
I have the following assertion

/*
        * If this ASSERT fails, a bad pointer has been passed in. It may be
        * totally bogus, or it may have been allocated from another heap.
        * The pointer MUST come from the 'local' heap.
*/
       _ASSERTE(_CrtIsValidHeapPointer(pUserData));

The Dll seems to have its own heap.

How can I solve this problem ?
