Yes, that's fine, although you can use the PM_REMOVE flag in the PeekMessage() call so you won't have to call GetMessage() right away.

Sorry, I posted this a couple of days ago then disappeared. I didn't post much info either (the problem then was me being totally dippy) so I thought I'd risk the wrath of you lads and post it again with more info, save the flogging for later please 
Anyway, short story is that I have to extract email addresses from a lot of files which have been exported from a database. There is no general format to these files, so its a hack & slash search to find them. The only things I have guarenteed is that there will be a space before & after the address and that the @ character will only be in the email addresses, not in any other fields. A sample of the file would be something like this but a lot bigger (roughly 2000 characters each) and they can contain more than one email address.

What I'm trying to do just now is write a ParseEmail(CString wholeFile) function that gets the file passed to it, and it works through picking out the email addresses. My problem is that CString isn't behaving how I would expect
while(whoIs.Find("@",0) != -1)
{
int index = whoIs.Find("@",0);
TRACE("@ character at position %d\n",index);
int end = whoIs.Find(' ',index);
TRACE("end = %d\n",end);
int pos = index-1;
CString ch;
ch = whoIs.GetAt(pos);
while(ch.GetAt(pos) != ' ')
{
pos--;
TRACE("ch = %s\n",ch);
}
CString email = whoIs.Mid(pos,end);
TRACE("email address = %s\n",email);
whoIs.Delete(0,end);
}
The problem after all this long windedness that the finding of the space before and after the @ doesn't work as I expect. It usually ignores spaces and other characters and returns me 50 letter email addresses 
Does anyone have an idea of how I could improve this function so that it actually works? Cheers and sorry for the 10,000 word essay

Strange, this had a 1.0 rating. Anyway...
Perhaps try CTokenizer: http://www.codeproject.com/string/tokenizer.asp[^]
The code would be something like this:
CTokenizer tok( YOUR_INPUT_STRING, " " );
CString str;
while( tok.Next( str ) )
{
if( str.Find("@") != -1 )
{
}
}

One of the great things about having a high post count is that my vote one a post counts for more than most people ( possibly everyone except Nish). I gave it a 5 to bring it back up. I don't get why some people vote posts the way they do.

eh, don't mean to be rude but f**k no I wouldn't work on something like that. Anyone who works on them deserves to have all of the spammers in the world thrown into a room with them and nuked alongside the <insert sweary="" word="" here="">.
Its all part of a contract I've been working on with an accountancy firm. Its a whole bigass project but the thing with the email address relates to them needing a central database with all the email addresses of their clients/partners/co-workers in the Far East and USA. The email part of it is pretty insignificant in the scheme of the whole project hence the bodge job before the demo next week

Nah, I just think that helping people spam more crap about getting a bigger ehhhhhh member  or sending your cash to a king fleeing his country so he can pay you back double is just asking to be shot. Spammers should have their testicle hairs pulled out by a lion, the people who write the mass-senders just need a good slap and to have their internet connections taken away.

What is that? Perl? Perhaps you are correct. I'm not a big Perl fan.

So what ? C# would also do it quickly with a regular expression. That does not help much if you're doing work on data from a data source in C++, now does it ?

If you want to get it right you better start off without CString. I've done RFC compliant mailparsing and you can believe me when I tell you that a working parser takes more that 200 lines of C++ code.
just as an example: <"Duh:my=mail-home"@[100.99.98.1]> is a perfectly valid mail address and yummy: "Jonny\"s Dumb" (who's he anyway) <jd@dumb.com>; too

Thanks for the answers Larry and the advice Andreas, the reason for using C++ is that this is a small part of a much larger project that I've been working on.
To be honest I only need basic email parsing just now because this is mainly for a demonstration next week for the company buying it so after 20 revisions of the interface and other features, they can get their hands on a demo so we can do a final usability test and start the intended users off with a good run through of the program.
Once this is done I can get down to the nitty gritty of trying to get proper RFC compliance rather than the quick bodge I'm trying to do just now. As I said, the email parsing is a really small part of the project that just now is getting pushed aside in favour of working on getting other things up to scratch. I've got a full week pencilled in for working on this and another thing next month but until then its bodgey bodgey for me.
blehhh, to many big posts in one day make my head hurt Thanks for the hints & tips guys

How do I make a toolbar like the one i exploror?
The criterion is that the combo-box part is resized as the mainframe changes size.
I've looked in the "All Topics, MFC / C++ >> Toolbars & Docking Windows" area but I couldn't find it.
I would be very pleased if anybody who has done this would reply the thread.
Thanks.

Hi
I have a problem with a application that i have written in vc7. It works perfect in Win XP and Win 2000.
But fails in Win 98 and Win ME.
This is what happends.
When i hover the mouse above a toolbar button the application terminates when the tooltip for the button is about to be shown. I tried to debug, and the debugger stop in comctl32.dll. But i don't know what to do about it.
The second problem i have is that i have a list control where i can edit the items on every row. I can have a DateTime control, edit controls and comboboxes.
It is no problem when i use the datetime or the edit controls. But if i begin to edit in a combobox, when i leave the combobox i get a GPF in User.exe. And the debugger can't give me any help.
Im guessing that all this have something to do with different versions of system dll's. But i'm not sure, and i don't know how to find out which dll's to update. Or if i could work around these problems.
So my question is how could i make my application work in win98?
Because it should be possible to write a application in XP and then it should work in Win 98, right? And i don't think that i'm doing anything advanced. So i can't understand why it won't work all the way.

There are two versions of the TTN_GETDISPINFO (formerly called TTN_NEEDTEXT) message, one ANSI and one Unicode. Make sure that your code isn't hard-coded to assume Unicode, because on 9x the ANSI version of the message is used.

That is an interesting thought. But i'm using the plain CToolBar that is created automatically by vc7 when i created my project. And shouldn't that one work on win 98?
I've found out that my combobox problem only occrus when i have a ordinary combobox dropdown list, and i can write text in the edit-ctrl part of the combobox.
The program does not terminate when i exit a combobox dropdown list. And this is strange, since i'm using the same combobox class for both types. This is the worst problem of the two that i have, so any little tiny idea on what i can do to find out the problem is appreciated.
And i think that it is strange that it works without any problem in win 2000 and xp.

Maybe i have this problem on another place in the code. The following code is a part of the OnToolTipText function:
#ifndef _UNICODE
if (pNMHDR->code == TTN_NEEDTEXTA)
lstrcpyn(pTTTA->szText, strTipText, 80);
else
_mbstowcsz(pTTTW->szText, strTipText, 80);
#else
if (pNMHDR->code == TTN_NEEDTEXTA)
_wcstombsz(pTTTA->szText, strTipText, 80);
else
lstrcpyn(pTTTW->szText, strTipText, 80);
#endif
This should handle the difference between XP and Win98, right?
But it doesn't. My program works fine in XP, but terminates in Win98.
Does it matter that i develop in vc7 on XP? And then try to run the exe
on Win98? But i think that it should work anyway.
Please, someone, help!!

Hi - I'm on WinXP using .NET Visual C++.
I am trying to draw unicode characters (phonetic symbols, specifically) to a CWnd using GDI... I dont' think I have to change my app to entirely Unicode to do this (?), but don't know why this doesn't work:
CFont font;
font.CreateFont(20,
0, // width
0, // escapement
0, // orientation
25, // weight
FALSE, // italic
FALSE, // underline
0, // strikeout
0, // char set
0, // out precision
0, // clip precision
0, // quality
0, // pitch and family
"Arial Unicode MS");
int iNumPhonemes = _phonemeList.GetNumPhonemes();
CPoint drawPoint;
CString str(TEXT(""));
memDC.SelectObject(&font);
for(int i = 0; i < iNumPhonemes; i++)
{
str = TEXT("");
WCHAR ipaCode = (WCHAR)_phonemeList[i].ipaCode;
str += WCHAR(ipaCode);
memDC.TextOut(40, 40*i, TEXT(str));
}
... where _phonemeList.ipaCode is just an integer number, the unicode decimal value of the required symbol. It seems to ignore the Unicode part and just print the character corresponding to the bottom byte of the unicode character.
Any ideas?
TIA

From the docs:
"The TEXT macro identifies a string as Unicode when the UNICODE is defined during compilation. Otherwise, it identifies a string as an ANSI string."
And since
<code>
BOOL TextOut(
HDC hdc,
int nXStart,
int nYStart,
LPCTSTR lpString,
int cbString
);
</code>
means that
<br />
memDC.TextOut(40, 40*i, TEXT(str));<br />
is not calling TextOutW() unless you define UNICODE.
