how to implement pop3 with VC++ PavanKumar Chatrathi18-Jul-01 1:06 PavanKumar Chatrathi 18-Jul-01 1:06  How to develop mailclient application in VC++ which uses pop3 protocol to retrew mails from serverlike MSExchange. Where i have to create database to usersid and password. how the application can be done. Pavan ch. Re: how to implement pop3 with VC++ Anders Molin18-Jul-01 2:44 Anders Molin 18-Jul-01 2:44  Hmmm, if I should answer all those questions, I would have to write the program for you. Search around here at CodeProject, I think there a couple of classes that receives POP3 mail. If you want to write it yourself, you should start to look at the WinSock functions (which you would use to connect to the mailserver), and then look at the POP3 protocol, so you know what commands to send to the server... - Anders Money talks, but all mine ever says is "Goodbye!"

C Virtual Namspaces and Drag &Drop operation pic17-Jul-01 23:10 pic 17-Jul-01 23:10  I've written a program to declare in the window explorer, a new namespace and virtual folders inside. But i cannot drag & drop a folder or a file from the the left tree view of the window explorer (items in the disk C for example) to a virtual folder in my new namespace (still on the left tree view of the window explorer). The flag SFGAO_DROPTARGET is on for the namespace and also on for each virtual folders when the IShellFolder::GetAttibutesof() method is called ! Someone can help me ?

Why did the func :OnChar not happened when a key pressed 17-Jul-01 21:10 17-Jul-01 21:10  I try to perform actions for the event WM_CHAR but this func not performed. Why ?????? Re: Why did the func :OnChar not happened when a key pressed Patrick Hoffmann17-Jul-01 23:00 Patrick Hoffmann 17-Jul-01 23:00  Some keys do not produce OnChar messages. But you may catch the WM_KEYDOWN and WM_KEYUP messages. rtfm! MSDN says... Remarks Because there is not necessarily a one-to-one correspondence between keys pressed and character messages generated, the information in the high-order word of the lParam parameter is generally not useful to applications. The information in the high-order word applies only to the most recent WM_KEYDOWN message that precedes the posting of the WM_CHAR message. For enhanced 101- and 102-key keyboards, extended keys are the right ALT and the right CTRL keys on the main section of the keyboard; the INS, DEL, HOME, END, PAGE UP, PAGE DOWN and arrow keys in the clusters to the left of the numeric keypad; and the divide (/) and ENTER keys in the numeric keypad. Some other keyboards may support the extended-key bit in the lParam parameter. Whistler: The WM_UNICHAR message is the same as WM_CHAR, except it is designed to send or post Unicode characters to ANSI windows.

Frankie17-Jul-01 21:02 Frankie 17-Jul-01 21:02  Hi, I have an application that makes use of a splitter window. One pane makes use of several (up to sometimes 20) CView deriven windows. Each of this views has a lot of child CWnd deriven windows and each such a window also has child controls like CCombo, CEdit CLisBox etc. Now I have a serious performance problem I think. My theory is that al the windows are 'eating' performance by means of their message queues, is this possible? And if so, is it possible to stop these queues for the above described views that are not active? Or is there a solution to decrease CPU use? Hope someone can help me with this. Regards, Frank. Re: Message queues of windows? Michael Dunn17-Jul-01 21:21 Michael Dunn 17-Jul-01 21:21  A message queue belongs to a thread, not a window, so you could have 15000 windows but they'd share the same queue. My guess is that any slowdown would be due to MFC having to walk the message maps of all the views whenever a message is sent to your app. --Mike-- http://home.inreach.com/mdunn/ Sometimes, arming yourself with a big pointy stake just won't do you any good. Re: Message queues of windows? Frankie17-Jul-01 22:02 Frankie 17-Jul-01 22:02  Ok..I think I understand my problem now. I have a lot of CWnd deriven windows in each view which all have their own message map, each of these windows also have child windows which also have their own message map. Some numbers: 10 view classes, with each 10 windows and each of this window 20 sub windows -> say more than 220 windows that have their own message map. Could this cause my program to be very slow? And is there by any means a way to speed up the proces, work around the message map, or let MFC know not to walk through the message maps of certain windows (say all windows in the views that are not active?)

I mean, when i give 2 to function it must point to record two ... I have algorothm for myself: m_rs->Move(lLink - m_rs->GetAbsolutePosition() - 1); lLink is variable that i get of user for pointing ... Do you have any good idea ?

We need to send email from an NT service... haven't come across anything so far. thanks n Re: Sending Email in Win32 17-Jul-01 15:11 17-Jul-01 15:11  How do you want to do it? MAPI, sockets, something else? Re: Sending Email in Win32 Nick Blumhardt17-Jul-01 16:42 Nick Blumhardt 17-Jul-01 16:42  oops- MAPI is what I was looking for Re: Sending Email in Win32 18-Jul-01 2:22 18-Jul-01 2:22  Check MSDN, the MAPI methods, oddly enough, are prefixed with mapi. I.E. MAPILogon, MAPISendMail, etc. Controls. John Uhlenbrock17-Jul-01 12:25 John Uhlenbrock 17-Jul-01 12:25  I have a group-box enclosing 4 check boxes. I want to keep the group box, but I also want to be able to check any number of the check boxes. How can I do this? As well, how can I keep my SDI formview based app from being re-sized? Thanks, John. Re: Controls. Tim Deveaux17-Jul-01 14:06 Tim Deveaux 17-Jul-01 14:06  Er - from memory if you play with the Group check box in the properties of the cb controls, you should get it - works for radio buttons too I think. In InitInstance you'll see the main window handled - if you call ModifyStyle to remove the WS_THICKFRAME style for it you should effectively make the window unresizable. Hmmmm might look at WM_MAXIMIZEBOX as well.. Re: Controls. Michael Dunn17-Jul-01 14:13 Michael Dunn 17-Jul-01 14:13  Check a checkbox with CheckDlgButton() - it doesn't matter how many you have or whether they're in a group box. --Mike-- http://home.inreach.com/mdunn/ Sometimes, arming yourself with a big pointy stake just won't do you any good. Dialog bars. John Uhlenbrock17-Jul-01 11:36 John Uhlenbrock 17-Jul-01 11:36  Still looking for an answer to.... MSDN states: "While it is normal to derive your own dialog classes from CDialog, you do not typically derive your own class for a dialog bar. Dialog bars are extensions to a main window and any dialog-bar control-notification messages, such as BN_CLICKED or EN_CHANGE, will be sent to the parent of the dialog bar — the main window." I do not know how to use a dialog bar's controls. I can load the dialog bar, but I can't activate the bottons so they may be pressed, I can't set text in textboxes, I can't set the status of check-boxes. How are you supposed to get variables associated with the controls on the dialog bar if you don't have a derived class. Thanks, John
