Re: CTime... Carlos Antollini19-Jun-01 6:43 Carlos Antollini 19-Jun-01 6:43  CTime tm = CTime::GetCurrentTime(); If you want to Know the Hour or the minutes, you can do: CTime tm = CTime::GetCurrentTime(); int nHour = tm.GetHour(); int nMin = tm.GetMinute(); etc. Regards... Carlos Antollini. Re: CTime... John Uhlenbrock19-Jun-01 6:45 John Uhlenbrock 19-Jun-01 6:45  I think my question was unclear. I don't understand why the CTime object has to be initialized that way. Why can't it be initialized like this: CTime tm; tm.GetCurrentTime(); - John Re: CTime... Carlos Antollini19-Jun-01 6:55 Carlos Antollini 19-Jun-01 6:55  Because the definition of GetCurrentTime is CTime GetCurrentTime(); And not void CTime::GetCurrentTime(); I think that this is a cuestion for the Microsoft Developers..... Is True, Is more is more intuitive of the other form, but they developed it of that way. Cheers!!!! Carlos Antollini. Re: CTime... Chris Meech19-Jun-01 7:15 Chris Meech 19-Jun-01 7:15  I'm not sure of the exact implementation details, but did you notice that the GetCurrentTime method of the CTime class is a 'static' method? That is the reason for how it is used. Why it's declaration is such, I don't know. That relates to how the developers decided to do things. Chris Re: CTime... Vikash Dubey19-Jun-01 10:55 Vikash Dubey 19-Jun-01 10:55  Yeah GetCurrentTime is a static method that is why you call it using that syntax. The method create a CTime object in this way CTime(::time(NULL)). The GetCurrentTime is creating a new CTime Object of which the member m_time contains the latest time.The assignment operator copies this value CTime tm; tm=CTime::GetCurrentTime();// operator=(const CTime& timeSrc) comes into action Mail back if you have more info Re: CTime...

Can I do similar things in VC++ 6? Thankyou Re: Graphs RobJones19-Jun-01 7:53 RobJones 19-Jun-01 7:53  Its easy to do... For example if you have just created a dialog type application you can right click on the dialog and pick Insert ActiveX Control, from here you can pick your ActiveX grid or excel controls.. or from the the menu bar in Visual C++ pick "Project" then "Add to Project" next chose components and controls.. then go to Registered ActiveX Controls folder. Have Fun!

Re: ATL Michael P Butler19-Jun-01 22:27 Michael P Butler 19-Jun-01 22:27  Look at the Implements keyword. Quick pseudo code example to give basic idea. Implements IConnection Dim obj as Object Dim Cookie as Long private sub Form_Load() set obj = CreateObject("myapp.object") Cookie = obj.Advise(Me) end sub private sub Form_Unload() obj.Unadvise(Cookie) end sub private sub IConnection_MyConnectionPoint MsgBox "Called by VC++" end sub How to integrate a feature as "standard" ? (Indeed to patch an existing OS function) ? 19-Jun-01 5:36 19-Jun-01 5:36  Hello, I'd like to know if it is possible and if so how, to indeed patch a Windows function in order to make all programs use it in standard. For example, softs that "skin" windows are able to change the default shape of windows. How such things can be achieved ? For example, how would it be possible to have windows with a border of 5 pixels wide instead of the regular 1-pixel ? Or how would it be possible to change the standardclose button image ? Thank's in advance, --Francois Re: How to integrate a feature as 19-Jun-01 5:49 19-Jun-01 5:49  i actually don't know how applications like TALISMAN "skin" windows, but there is a SDK from microsoft called "Detours", which enables you to replace a regular API function with your own. have a look at: http://research.microsoft.com/sn/detours/ How to catch the message of a window olivier19-Jun-01 5:10 olivier 19-Jun-01 5:10  I have the handle of a window that has been created by an Active X and I want to hook its right click message. Any idea ? Thanks Re: How to catch the message of a window Tomasz Sowinski19-Jun-01 8:26 Tomasz Sowinski 19-Jun-01 8:26  You need to subclass the window. The topis is too complex to discuss it in detail here. Good starting point is CallWindowProc docs in MSDN. Paul DiLascia created MFC-based solution called CSubclassWnd - it first appeared in June 1997 issue of Microsoft Systems Journal. The article is available in 'Periodicals' section of MSDN. Tomasz Sowinski -- http://www.shooltz.com.pl CPropertyPage focus problem Doug Batchelor19-Jun-01 5:02 Doug Batchelor 19-Jun-01 5:02  Hello, I've encountered a CPropertyPage problem that has me very puzzled and may be a bug. Perhaps someone has seen it and can offer an explanation and/or solution. Here's the situation. Windows SDI app, VC++ 6.0, Windows NT 4.0. I used class wizard to create the app and used CFormView for the view class. Added a dialog box and using the dialog editor changed its properties to: Style: Child, Border: Thin, Title bar, Disabled. I then added a single Edit Box. Then using class wizard I created a CPropertyPage class based on this dialog and also created a CPropertySheet class. Added code to show them. Everything works as expected, except: You cannot set the focus on the edit control by clicking on it with the mouse. You can only set focus to it by using the tab key. I have a very small project that shows the problem clearly. If anyone has any insight it would be greatly appreciated. Dougb Hiding a splitter pane? Jim A. Johnson19-Jun-01 4:28 Jim A. Johnson 19-Jun-01 4:28  I am working on an Explorer-type app, and would like to hide the tree view (left side). Note that I don't want to delete or destroy it, since the tree conatins important structural data that I don't want to lose. I've found no examples for thids. Some suggest setting the row width to zero, but the spplitter bar still appears. Any suggestions? Re: Hiding a splitter pane? Tomasz Sowinski19-Jun-01 8:34 Tomasz Sowinski 19-Jun-01 8:34  I'm afraid there's no silver bullet here - you'll have to play tricky. When user switches the tree off, reparent the panes using ::SetParent or CWnd::SetParent, hide the tree and destroy the splitter.
