Critical sections block all the time, that is their job. If you get a deadlock which is what you are talking about then that is a separate issue. This can be as simple as the code inside a CS getting into an endless loop and never returning. CS's should be used for the shortest amount of time and least amount of time as possible. You need to ensure try - catch is used and any exceptions always unlock the CS.
I suggest you go and read some heavy books on multithreading, thread synchronization, deadlocks etc. This is a very difficult area and unless you have a very good understanding of the basics you will have problems.

does anyone have any ideas (I know there's lots of brute-force/ugly ways) to handle something like :-
CString strNext = genNextSeq("aa");
Where the correct progressions in the sequence given "aa" as the 'current' sequence are ab, ac, ad ... az, ba, bb, bc .. zz
Im just interested - it came up in a log file rotation scheme I was using - I just made do with yyjjj_xx where yy=year, jjj=Julian, and xx = 01..99

Write a base26 number class. So, your base26 'a' would have value 1. Your base26 'aa' would have value 26+1=27, your base26 'bc' would have (26*2)+3=55. Maybe your class could have a member which would generate a string version of the number held internally. Kinda like converting between hex and decimal, except instead of base16 we have base26. Sounds kinda interesting.

thanks Chris - I was sort of heading down this track, but expressing it like that, ie 'base26' is what seals the decision - what I was thinking about was the same, doing mod(n,26) etc, but not expressed as succinctly as you !!!
Chris Richardson wrote:

yeah, funny, we take base10 for granted - this isnt that much different, except the representation of the characters changes
I like the member idea as well to generate the string from the internally held numeric value .. when I'm done I'll try to post it for a good flaying here in CP
thanks & cheers, Garth

Hi,
In my program, I have 56 Edit Controls where I can type the names of 56 players. Presently, I'm using ON_EN_SETFOCUS for every Edit Control to set an INT variable that tells me which Edit Control has the focus. When I want to print, delete or view the result of the player in focus, I check the variable and than print or delete the good player.
Is there an easier way to know the ID of the Edit Control in focus? Like when I want to print a player's results, just get the Edit Control ID in focus at this moment, compare the ID and identify the player.
Here's a sample of my code:
....
ON_EN_SETFOCUS(IDC_NAME13, OnEnSetfocusName13)
ON_EN_SETFOCUS(IDC_NAME14, OnEnSetfocusName14)
END_MESSAGE_MAP()
void CMainView::OnEnSetfocusName14()
{
PlayerInFocus = 14;
}
What I would like to do:
void CMainView::OnPrintPlayer()
{
Get the control ID in focus
if(Control ID == 14)
Print Player 14
else if(Control ID == 15)
Print Player 15
else if ...
}
Thanks
Dave

just make sure your resource ID`s are in consecutive
eg
IDC_NAME1=21
IDC_NAME2=22
.
.
.
IDC_NAME26=46
and then you could use in messagemap:
ON_NOTIFY_RANGE( NM_SETFOCUS, IDC_NAME1, IDC_NAME26, SetPlayerFocus )
define SetPlayerFocus in header as:
afx_msg void SetPlayerFocus(UINT nid, NMHDR* pNotifyStruct, LRESULT* pResult);
void CMainView::SetPlayerFocus(UINT nid, NMHDR* pNotifyStruct, LRESULT* pResult)
{
m_nPlayerWithFocus = nid - IDC_NAME1 +1 ; //results in 1 for player1 etc...
pResult = 0;
}
void CMainView::OnPrintPlayer()
{
// print whatever you like, m_nPlayerWithFocus contains value of last edit field that had focus
}
I think that should roughly do the trick...
.
.
.
.
other option, maybe even better skip the setfocus function just do:
void CMainView::OnPrintPlayer()
{
CWnd * wndFoc = GetFocus();
if( !wndFoc )
return;
int nCurrentPlayer = wndFoc->GetDlgCtrlID() - IDC_NAME1 +1;
if( 0<nCurrentPlayer && MAX_PLAYERS >=nCurrentPlayer )
PrintResultsFor(nCurrentPlayer);
}
|
|
|
|
|
As a note, you could use:
CWnd *pFocus = GetFocus();
if (pFocus && pFocus->IsKindOf(RUNTIME_CLASS(CEdit)))
{
UINT id = pFocus->GetDlgCtrlID();
// makse use of the controls id here....

Thanks a lot, that's exactly what I was looking for!

Maybe I'm missing something, but why can't you just GetFocus()? This will return a CWnd* of the window having the focus.

Are you talking about the way Windows XP hides the underline until you press Alt?
If you are, this is a setting that you can change in the Display Properties (Control Panel -> Display or right-click on the desktop).
There you go to "Appearance", click on "Effects" and unselect the "Hide underlined letters for keyboard navigation until I press the Alt key".
I don't know how to change this from inside a program, but as it is a user's setting, you better keep it as the user choosed it to be.

The feature is not exclusive to Windows XP.

Check out the NoChangeKeyboardNavigationIndicators value in the following two registry keys:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

I didn't know... 
I still work with 2k but never noticed that "feature"... 
Anyway, thanks for the info about the registry.
(although I still think that it is something not to be messed with, as it is an user setting)

If you want to change it from inside a program, probably the best way to do it is like so:
BOOL a_bSet = TRUE;
SystemParametersInfo( SPI_SETKEYBOARDCUES, 0, (PVOID)&a_bSet, SPIF_SENDCHANGE );

Hi
I want to manipulate the MFC classes to intercept TCP calls from normal applications like Internet Explorer or WS_FTP to 'connect' using the connect function in my socks client instead of the normal TCP call.
However, I am not sure what to use to implement this.
Can anyone tell me how to use MFC classes to do that?
Thanx!

Could someone please take the time and explain how to add tooltips to an existing mfc application?
I have an edit box that I would like to add tool tips to so the user knows exactly what needs to be input. I read something on msdn about it but for me msdn is not clear.
thanks for your help.
