Directly calling framework... Jamie Hale22-Apr-02 5:04 Jamie Hale 22-Apr-02 5:04  How do we feel about directly calling framework handlers? I'm talking about setting up a DC and calling OnPaint(). I'm talking about calling the WM_COMMAND handler for a specific menu item. Personally, I find this quite lazy. What should be done it to create a routine that does the required action, and then have both the framework handler and the user code call the routine. Am I psycho?

Re: Directly calling framework... Paul M Watt22-Apr-02 6:05 Paul M Watt 22-Apr-02 6:05  I think that it is fine, as long as only your class can call the framework handlers directly. The way that I look at it, is you are combining common functionality into one place. That common code needs to be accessed. Do what makes the most sense for the situation. Whether it is sending a message to the window and letting the message handlers process the message, or calling the framework handler directly.

In my current MFC source code, I have two classes, the usual "MainDlg" and .. euhm ..let´s say "A", which is not a CDialog based class, but another kind of class running separately (in its own thread). In a function of A, I send a message with PostMessage(MSG_MYMESSAGE,35,47); and I´d like to get it in my MainDlg. A way to do this is to declare : <br /> BEGIN_MESSAGE_MAP(CMainDlg, CDialog)<br /> //{{AFX_MSG_MAP(CMainDlg)<br /> ON_MESSAGE(MSG_MYMESSAGE, OnMyMessage)<br /> //}}AFX_MSG_MAP<br /> END_MESSAGE_MAP()<br /> This triggers the OnMyMessage() function, but i do not know where to find my two parameters 35 and 47 (that is, the WPARAM and LPARAM), and I really need them. So, is there any way to get these parameters ? Thanks 4 your help.

Re: MFC application and JavaScript Michael P Butler22-Apr-02 5:04 Michael P Butler 22-Apr-02 5:04  Have a read of http://www.microsoft.com/mind/defaulttop.asp?page=/mind/0297/activescripting.htm&nav=/mind/0297/inthisissuecolumns0297.htm It's a good starting point for implementing active scripting in your application. Michael Windows CE & ListView ov22-Apr-02 4:14 ov 22-Apr-02 4:14  How can I change the height of the row in report-mode of the ListView? The simple way with WM_MEASUREITEM is not working. Or, maybe, there is another way in WinCE to display a list of my own items? I need something like TODAY screen, but with the same row's height for all rows and with scrolling. With the best regards, Vitaly.

ADO Exception Handling soup22-Apr-02 4:13 soup 22-Apr-02 4:13  Hi, I have small problem. I am implementing exception handling as recommended in MSDN and in the KB articles, thus: try { objConn.Open(...); } catch(_com_error &errorConnecting) { strError = (char *) errorConnecting.Description(); } However, if there ever is an error, I get a first-chance exception on the catch line. I have step debugged the code and it is that line. Despite the exception, the code continues and functions correctly. Is this a problem I should be worried about when I move to release build, and if so how can I prevent it? Thanks in advance, Simon Re: ADO Exception Handling Rutger Ellen22-Apr-02 4:37 Rutger Ellen 22-Apr-02 4:37  maybe you have break always on for your exeptions To check, start the program whith step into(F11) and look under Debug->Exceptions You'll get a dialog that allows you to set up the exception handling during debugging. Check the Microsoft C++ Exception, if this says stop always then indeed you will get the first chanche... You can change it to stop if not handled and get notification only if an exception is not handled, but this includes cach all handling from the MFC framework. (you could also just press ctrl+F5 to start the program outside the vc debugger and see what it does) good luck Rutger Time conversion Sameer Maggon22-Apr-02 2:24 Sameer Maggon 22-Apr-02 2:24  Hi, I have a string which have a time in format "HH:MM" How do i convert it into CTime or time_t Please help Re: Time conversion -Dy22-Apr-02 2:48 -Dy 22-Apr-02 2:48  The CTime object doesn't have a CString constructor. So you will need to do the following: <br /> CString strTime = "13:30"; // 1.30 p.m.<br /> CTime tm = CTime(1970, 1, 1, atoi(strTime.Left(2)), atoi(strTime.Right(2)), 1);<br /> I haven't tested this, so let me know if it works ...

They can't have terminated within 5 seconds because if they have then using INFINITE wouldn't hang on WaitForMultipleObjects(). UI threads are a pain the behind in MFC and you can easily get into a deadlock. Have you tried #ifdefing out all of the code inside the thread functions and see if WaitForMultipleObjects() behaves as you expect? Also add TRACE statements at the end of the thread functions so you can see when they finish. Threads in MFC are the bain of my life.
