How to realize communication problem?
I am working on a project in which I read/write data via rs-232 from/to my
Windows application to/from an microcontroller.
Now, my boss wants me to write a library which he can use for different
microcontrollers. This library should store any changes of data. So the
desired microcontroller should just be able to pick up the data.
You can think of it this way: Me, representing the Windows application, put
a sheet of information into a drawer. A buddy of mine, (representing a
microcontroller) can go to the drawer an pick up the sheet for further

If anyone could help me with this I would be more than grateful.
We have moved our Exchange Server to a DMZ with public address space, we are
trying to connect Outlook 2003 clients to the server from our private address
space. The routing is all set up correctly as we can ping both ways which
leads me to believe it's a port problem, i.e. I haven't opened enough up.
I've searched TechNet for the relevant documents and have made the needed
changes where necessary. I have set a high static port in the registry on the
exchange server and our domain controllers for RPC AD re...Communicating
I am writning a program that will communicate with a server (Linux) using
RS232 or TCP/IP. The server is using the same protocol for both. The
protocol is rather 'chatty', so for each command there is a lot of sending

It works but the program freezes until the communication is done...

I have 2 threads used for serial communications (receive and transmit). I've
wrestled with a couple of issues off and on for long time.
1. I currently use a ring buffer for the receive thread to put data in. When
data is received, the thread uses PostMessage() to send a message to the
application to process the data. This works for the most part except now I
have encountered a problem when I display a MessageBox() while processing
received data; I get more messages from the thread that seem to interfere
with the process. ie the MessageBox displays twice for some reason. When I

What are the ports required to be opened from RODC to RWDC.
While the RODC does only uni-directional replication, the RODC does need to

seen anything in the other direction.

I recently linked a Passport account with my Money file and now I can't
import my OFX files from my bank anymore. I saw some other posts related to
MSN Billpay which I've never used. It looks like this is a known problem.
Does anyone know of a fix? I thought the problem was my bank so I went a
couple of weeks before investigating this issue; now my backup file is also
corrupted. I tried the Money repair function but to no avail.

like maybe a memory mapped file handle or something, which the thread would

I have a question regarding the communication between the two dialogs.
Basically I am having a main dialog in which I am embedding another

no relation between them except the main dialog is creating the

Now, main dialog is having some static buttons and I have assigned the

The child dialog will contain the control on runtime. So, whenever the
