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.

SHAutoComplete Edit

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.
Regards,
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 | :)

shift key and button click

ns2-Apr-03 4:49

2-Apr-03 4:49

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,
ns

Max.

what about GetAsyncKeyState()? simply enter the button handler and test the shift key status. could this be a nice solution?

I'd prefer GetKeyState - it reflects they keyboard state of the message currently processed (i.e. it's "closer to the actual click")
