Does anyone know if there is a way how to export emails from the Inbox/Outbox into .msg files programmatically?
I tried using the Outlook Object Model, but it asks the user for permission to access the mailboxes and ideally I would like to avoid that (no, i'm *not* writing a virus... - i just would like to do away with user interaction while the program is running  ).
I also tried using MAPI, and i managed to read emails individually into the IMessage interface, but I can't see how I can stream its properties to a file without iterating on the properties one by one (and potentially risking modifying one property indadvertedly and ruining the entire message).
My recent attempt has been with CDO but again, the MessagePtr interface in cdo.dll doesn't seem to support any streaming.
Anyone has a better idea?

I have installed on my PC a PCI card which implements RS422 via an API.
Now this API has calls to install and uninstall an interrupt handler; and use this handler to drive conditions such as data sent.
Now I have used the interrupt handler via a Win32 console application, but it seems not to work when I try and use it in a MFC Dialog application - Dont get any interrupts.
I dont know if the handle should be a class member of the dialog, at present its not as thats the only way I could get it to compile.
Two questions:-
1. How does this scheme work (just a simple overview please)
2. I was hoping to use the interrupt to handle time events that need to take place every 40 msec. Can interrupt handlers be installed (via this API) for a MFC application.
Many thanks,

Pehaps you should ask the providers of the API these questions.

I have done so, but the responce can take quite a while.
I think the problem is around the MFC framework and they may not wish to comment or offer support on that; i.e. works for a win32 and a straight C program, hence the question in this forum.

OK, perhaps you ought to mension who wrote the API. Perhaps others here have used it and know what quirks it has.

Hi,
I am upgrading the underling database in my application from Access 97 to Access 2000. I took the approach that I need to update STDAFX.H. Within this resource file is an #include of afxdao.h. I can’t find it on anywhere on my system. (everything compiles ok so it does not seem to be a problem not being there.
Is this the correct approach?
If a down load a new version where does it go in my project
I am using CV++ Can someone assist me in the right direction?
Thanks
TomH

A change to stdafx.h should not be necessary simply because you went from Access 97 to Access 2000.

If you've commented out the #include <afxdao.h> statement and your application still compiles ok, it obviously means the file is not needed.

I found it on my machine in the ...\VC98\MFC\Include folder.

Thanks so much.
I can't believe I missed it. I have upgraded my app to Access 2000 and so far it works. Still more testing to do.
I had to make some minor changes to Daocore.cpp file in the MFC SRC directory and some minor change in my app.
I get lots of answers on this board. Thanks much for all you do.

Generally not considered a good idea. This requires that you rebuild and redistribute the MFC DLLs.

My suggestion would be to notify the author of the article, the CP webmaster, and the author of the book. Posting such a message to this forum really serves no purpose.

Anyone pls can help me on this: i want to read the signal I apply to the line in on the soundcard. It is not necessarily an audible signal ... I simply want to use the soundcard as an AD converter. Thx in advance.

I am working on a VS.net project. The project has a backup, debug, release, hlp, and res folder. I only want to save the required project files to a version manager program and not save any unnecessary files like .obj files, etc. Which folder(s) contains the necessary files for a project that should be saved??

Your best to back up your main project directory, minus the debug and release folders. The company should keep a copy of the development enviroment and related files, incase the code needs to be recompiled/debuged in the future. That is if the company changes the development eviroment in future years, they need to be able to reproduce the origanal eviroment years down the road (or until the program is no longer supported).

look it up in the header file..
If you don't know which is the header file that defines it, do a search for a *.h file with the constant you wonna know the value of. Make the search case sensitive to avoid too many invalid files... But I guess with a const like PURGE_TXABORT even case-insensitive search will result in correct file...

Place the cursor anywhere on the PURGE_TXABORT value and hit the F12 key. You may be asked if you want to build the browser database.

Why? What does that have to do with my reply to wk_vigorous? Knowing where something is located is one thing, but knowing how to find it is another.

I've read a few times that "..doing it THIS operation is no faster than doing it THAT way; just look at the assembly after it's compiled" - or something like that. I've used the Win32 disassembler to look at code, and even seen the assembly for an .exe in VS. But if I write a function, how can I view the assembly for that specific function, so that I could see which takes more operations?
int i = 2, x = 2;
int j = x + y;
sprintf("%d",j);

Are you referring to the /FAs compiler switch?

I really don't know. I'm trying to find out how I can view the difference between this:
//hypothetically, GetRate() performs some intensive calculations that returns an int
for(int i = 0; i < 5; i++)
{
int j = GetRate() * i;
}
and this:
int x = GetRate();
int j;
for(int i = 0; i < 5; i++)
{
j = x * i;
}once they're compiled
int i = 2, x = 2;
int j = x + y;
sprintf("%d",j);

The latter is going to be a bit more efficient since the GetRate() function is only called once. Also, since the value of x does not change, the compiler is likely to optimize that by using a register.

I already understand that (not that I usually do  ) Just in case you didn't know, I am the programmer formerly known as 'bdiamond'. Anyway, I was talking about for other operations that I might not be familiar with. I wrote in another forum once (please CPians forgive me) that using the '+=' operator was faster with CStrings because I read that in a game programming book. One of the forums moderators told me there was no difference. So I put a breakpoint in my code (release version) in an arbitrary function that I used just to test this by going to debug->windows->disassembly and went back throught the disassembly, and this is what I got for two CStrings that started off as "test" and then had "add" concatenated to them.
str += "add";004015BC push offset string "add" (4037D0h) <br />
004015C1 lea ecx,[esp+8] <br />
004015C5 call dword ptr [__imp_ATL::CStringT<char,StrTraitMFC_DLL<char,ATL::ChTraitsCRT<char> > >::operator+= (4031DCh)] <br />
<br />
str2 = str2 + "add";<br />
004015CB push offset string "add" (4037D0h) <br />
004015D0 lea eax,[esp+4] <br />
004015D4 push eax <br />
004015D5 lea ecx,[esp+10h] <br />
004015D9 push ecx <br />
004015DA call ATL::operator+ (4011C0h) <br />
004015DF add esp,0Ch <br />
