    Whenever you think there's a solution to something like this, there generally is. You just need to take a big tug of coffee and think it through.

    Re: Slow Debug

    Sounds like it could be a memory problem.

    Are you out of available memory when debugging?

    If so, the system will switch over to using (very slow) virtual memory.

    You're very welcome :)

    Re: PostMessage using CStrings and memory leaks??

    It is not ok to pass MFC objects across thread boundaries as has been described here. It's not really a question of memory leaks, it's more a question of how MFC does it's thing behind the scenes.

    Re: Pipes vs. Mailslot and similarities

    Well, their function is fairly well described in the help, but if you just want a quick comparison, there are a few to add to your list:

    Re: CSoket, Receive stops

    CSocket is designed to operate in "blocking" mode, this means it will wait until the requested operation completes, or an error occurs.

    Specifically, in your example, it looks like the first call...

    Re: To count records in a mdb file

    It looks as though you are using DAO to access the database here.

    Switching to ADO would have significant benefits, including the ability to perform a GetRecordCount on a recordset.

    Re: query top10 value

    I do not beleive this to be correct.

    The order by will be called before the top 10 is selected, which should give you what you desire. This will work in Access.

    Re: DCOM or SOCKETS

    Use sockets wherever possible. DCOM sucks and is very buggy and sensitive to security settings.

    I've used DCOM several times - it has never been easy to use. Sockets are much more predictable (and...

  16. Re: 'PMYDATA' : undeclared identifier - My first thread (a crap shoot)

    As you have it, the call is going to the CWinApp derined override of CreatThread, which does not have 6 parameters.

    What you need to do is to force the use of the global CreateThread function by...
