Maverick24-Jul-05 18:47 Maverick 24-Jul-05 18:47  Hello.. I made a dialog resource with three CButton's and a CEdit for use on a CDialogBar.. the dialog resource is set to WS_CHILD.. Now when i used the resource on a CDialogBar.. and i used CDialogBar directly without subclassing it, the buttons is always disabled... But i didn't set it to disabled on the resource editor.. Why is this? The scenario is that I have a CDockBar docked on a mainframe, and i placed a LayeredCWnd on it as its child..Now the LayeredCWnd has the CDialogBar as its child.. Then when i run the program the buttons in the dialogbar is always disabled, while the Edit control is not.. "WatcH the BIrDiE!" Re: Buttons are disabled on dialog templates,. Marc Soleda24-Jul-05 19:37 Marc Soleda 24-Jul-05 19:37  I don't understand why it's happenning but you could force to enable these controls when you initializes the dialog (OnInitDialog): m_button.EnableWindow(true); m_edit.EnableWindow(true); Hope it helps, Marc Soleda ... she said you are the perfect stranger she said baby let's keep it like this... Tunnel of Love, Dire Straits. Re: Buttons are disabled on dialog templates,. krmed25-Jul-05 2:45 krmed 25-Jul-05 2:45  One reason they may be disabled is that there is no handler for them. Since you say the DialogBar is on your MainFrame, add handlers in the MainFrm class for the buttons. I'm assuming MFC here, and MFC automatically disables items it can't find a handler for. Hope that helps.

Re: Buttons are disabled on dialog templates,. Maverick25-Jul-05 4:33 Maverick 25-Jul-05 4:33  hey, thats a good idea.. im gonna try that.. tnx but still want to know why the buttons are disabled by default when im using dialog bars -- not dialog boxes.. regards, Maverick "wATCh THe BirDIe!..." Re: Buttons are disabled on dialog templates,. krmed25-Jul-05 4:58 krmed 25-Jul-05 4:58  Is the handler in your MainFrm class or some other class. Since the DialogBar is in the MainFrame, that's where the handler needs to be. If it is there, I'm at a loss why the button is disabled. Good luck.

I want to get the path of the file which is currently opened in the notepad. Please let me know. Thanks, E.Veera Raghavendra. Re: Getting the path Christian Graus24-Jul-05 18:31 Christian Graus 24-Jul-05 18:31  You want a third app to find the path to the file open in notepad ? If notepad has a MRU list, it's probably in the registry, otherwise I reckon you're in trouble. Christian Graus - Microsoft MVP - C++ What is the difference between CArray and CTypedPtrArray? KeyL24-Jul-05 17:47 KeyL 24-Jul-05 17:47  What is the difference between CArray and CTypedPtrArray? The CTypedPtrArray only could contains pointer, but the CArray could contains pointer and object. When should I use CTypedPtrArray? Thanks, Ray Re: What is the difference between CArray and CTypedPtrArray? Christian Graus24-Jul-05 18:30 Christian Graus 24-Jul-05 18:30  To be honest, they are both crap, and you should use std::vector. However, the TypedPtrArray is obviously a specialisation, so I'd guess if you must use non standard containers that don't offer an algorithm library, use CTypedPtrArray when it fits. You have the MFC source code on your hard drive, so you can look at the source if you want to know exactly what it's doing.

For example: CArray<cstring, cstring&=""> strArr; We only could put CString into the strArr. But in MSDN， it's not type-safe. Thanks Ray Re: Why CArray is not type-safe? Christian Graus24-Jul-05 18:32 Christian Graus 24-Jul-05 18:32  CArray is crap. What was your question ? Which doc are you looking at ? I reckon it says it's not thread safe. Christian Graus - Microsoft MVP - C++ Re: Why CArray is not type-safe? KeyL24-Jul-05 18:40 KeyL 24-Jul-05 18:40  Thank you, Christian. MSDN said the CArray is not type-safe. You could check it. http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vccore/html/_core_Collections_Topics.asp It's very strange, CArray is a template based collection classes. Why it's not type-safe? Re: Why CArray is not type-safe? Christian Graus24-Jul-05 18:43 Christian Graus 24-Jul-05 18:43  it does not say that at all. 'Tip The nontemplate collection classes have been provided by MFC beginning with MFC version 1.0. If your code already uses these classes, you can continue to use them. If you write new type-safe collection classes for your own data types, consider using the newer template-based classes.' This tip is really old, seeing as CArray is itself old, obsolete code since the C++ standard which is a few years ago now. They had a generic, non-template version, which was not type safe. Then there is the template version ( which is crap, but ) which is type safe. Nowadays, you should use neither, you should use the stl::vector class. Christian Graus - Microsoft MVP - C++ Re: Why CArray is not type-safe? KeyL24-Jul-05 19:44 KeyL 24-Jul-05 19:44  I think CArray is type-safe too. But do you see the Table of “Characteristics of MFC Collection Classes” in MSDN? The last column is “Is type-safe”, in this column CArray is “No”. Maybe it’s a publishing bug. Thanks, Ray Re: Why CArray is not type-safe? Christian Graus24-Jul-05 20:34 Christian Graus 24-Jul-05 20:34  I found the list. Who cares ? You still would be better off not to use it.
