Annoying html tags - i meant:

static_cast<CParentClass*>( GetParent() )->RunParentFunction();

IT works!! The only thing is that I think in your earliest post with the reinterpret_cast, the <> were missing so I guessed you meant:

m_pParent->SendMessage(MSGE, ndummy, reinterporet_cast<UNIT>(this));

I did this by deducing it might be what you meant and its seems fine. Is this indeed what you intended I should do? Your post says

interpret_cast (this) but it wouldnt compile that way--- not until I put in the type to cast to.....
So is that okay or did you mean something else?
Thanks!

Appreciate your help,

Custom Win32 Button Class

2-Apr-03 10:36

Hi all, I am trying to develop my own win32 custom button class. I was just wondering if anyone knew where there was a good article on this as I am a little stuck on handling mouse messages. I would also like to make it a bit more generic so that it did not rely on windows messaging so I could derive a class for use with DirectX to custom draw the control in the appropriate state or use GDI for windows apps. Its more the windows messaging thats the problem, unless I use TrackMouse...() I never know when to turn o the highlight state, and have other problems if I use it with WM_SETCURSOR (I can't see if the left mouse button is down). Any help or links would be invaluable,

Many Thanks,
Alan.

P.S. I'm not interested in sub-classing MFC or win32 buttons Smile | :)

this is my own complete implementation.

Access ActiveX via Dialog the nonMFC way?

Folks.... this is a repeat from 'General Discussion' message board, but I will not repeat in its entirety.

I asked there (and code provided) if it is possible to access using NO MFC, a dialog box with an activeX control placed on it (DataGrid)?

I have been able to access a Dialog box (nonMFC) but once a ActiveX control was placed on it, WM_INITDIALOG never gets called.

Please look in the 'General Discussions' messageboard for more details and with code provided.

Thanks to all who responded in advance!

Direct3D MDI... nasty!

Just a straightforward question: is it possible to have a virtually unlimited number of Direct3D (8) views open in an MFC/MDI application? I guess that only one drawing surface should reside in video memory at the particular time, while these of inactive views somehow get swapped to the RAM. Eek! | :eek:

If you happen to know the solution, or know someone who knows - I would greatly appreciate any help with this nasty problem. Mad | :mad:

What can cause Warning: calling DestroyWindow in CDialog::~CDialog -- OnDestroy or PostNcDestroy in derived class will not be called.

After closing my app the debugger reports this warning:

Warning: calling DestroyWindow in CDialog::~CDialog --
OnDestroy or PostNcDestroy in derived class will not be called.

Any ideas what can cause this? What can I be doing wrong? What should I look for to correct this? Thanks.

You're probably deleteing a modeless CDialog without first calling its DestroyWindow().

Ravi,

Thanks for the feedback. I think these are being caused from property pages of a property sheet. Does this make sence? If so how do I correctly delete pages from a sheet? Thanks!

Is your CPropertySheet class modeless? Or, do any of your property pages display modeless dialogs? Or both?

Ravi,

Thanks again for a reply. It is a complicated app. It is MDI using doc/view model. The veiw of the doc/view is split (with a splitter). One pane of the splitter is a view where I create the property sheet and the property pages. So, they are modeless as I can filp thru the pages and do work in the other panes of the split view.

When you close the view, make sure you call the property sheet's DestroyWindow(). This should take care of the problem.

When the view gets created, do:

m_pPropSheet = new CMyPropSheet (...);
ASSERT (m_pPropSheet != NULL);
m_pPropSheet->AddPage (...);
m_pPropSheet->AddPage (...);
m_pPropSheet->AddPage (...);

When the view gets destroyed, do:

ASSERT (pPropSheet != NULL);
m_pPropSheet->DestroyWindow();
delete m_pPropSheet;

showing html in explorer bar-newbie question

I made an explorer bar using ATL COM. I initially made the explorer bar using the registry entries, but that doesn't meet my needs because I need to do some processing. Does anyone have advice of how I'd show an HTML page in the explorer bar? Any insight would be appreciated.

Thanks

Melinda

I'm replying to my own thread, heh.
I could use a HTML control and host it in the explorer bar. Then I could use IWebBrowser2::Navigate() to browse around the Internet because the HTML control has a member CComPtr<IWebBrowser2>. I read that I could use the ATL class CAxWindow<>...how do I create that as the host in the explorer bar?

Thanks.

Melinda.

I have an edit control which has autocomplete feature. I could activate it by calling SHAutoComplete function.

Now I would like to add an url to the history if it doesn't exist in the url history.

How can I do this ?

Take a look at this interesting reg key: HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\TypedURLs. You could manually iterate values to see if an item exists, adding the new URL if it doesn't; or use IUrlHistoryStg::AddUrl()[^]

CEdit enhancement

Hi folks,
I need a ligth CEdit enhancement that allows me to automatically insert carriage-return/line feed when the text does not match the control width. Just before spending a day in coding it I wish to know if someone has something similar. If not I will be glad to share it w/ you if interested otherwise I'll be glad to save a day (it's getting hot in Italy);P.

Andrea

If I understand you, you should just be able to check the Multiline check box in the edit controls properties.

No, it does not work: multiline allows the text to be displayed in more than a line, but does nothing about the placement of CR/LF chars.
This functionality is present in the static text box!
thanx Smile | :)

I want to make my button click do two different things : one for when the button is pressed normally and the other for when the shift key is held down and the button pressed. So what do I look for within my click handler that can branch me off into one response or another?

Appreciate your help,
