I should have been able to figure that out!

Thanks!

I'm trying to use the PSM_QUERYSIBLINGS message to query information between some CPropertyPages.

It works great if the pages have already been "shown" but the property page class never gets the message if the property page tab has not already been clicked on for that page. I thinks it's the issue of the propertypage window does not get created until it needs to.

How can I use PSM_QUERYSIBLINGS to get information from another propertypage object before the propertypage window is "shown"? Is there a way to force all the property page windows to exist from the start?

PROPSHEETPAGE Structure
...
PSP_PREMATURE flag:
"Version 4.71 or later. Causes the page to be created when the property
sheet is created. If this flag is not specified, the page will not be
created until it is selected the first time. This flag is not supported
when using the Aero-style wizard (PSH_AEROWIZARD)."

I saw that earlier but my first question was does version 4.71 represent? MFC 4.71 ? or the control version is 4.71 ?

And my next question was concerning the PSH_AEROWIZARD. Does that mean if someone uses the page on a Vista box with Aero turned on, PSP_PREMATURE will be ignored?

Thanks for the response.

Shell and Common Controls Versions[^]

I'm not sure about the aero flag and/or Vista.

Regardless, sending messages to windows that don't exist isn't
going to work (obviously).

As David Crow mentioned, there shouldn't be any need to send messages to
pages the user hasn't (and may never) interacted with yet. If a page needs
some initialization value or needs to initialize controls, then it should be done
when the page receives the WM_INITDIALOG message and/or the PSN_SETACTIVE notification
(OnSetActive() in MFC).

Thanks.

Why would you need to query a page that has not been interacted with by the user?

Enabling/disabling fields in the other pages (that might be active) that depend on the value of another page (Actually the member of the page class)

Can't you just use the values that the page would be initialized with?

Is the OK button being handled by the sheet itself?

Thats the goal. Thats what I'm trying to accomplish by asking if any other page has a certain flag set so this page can disable the appropriate fields.

No, the OnApplyNow() is handled by the sheet. I don't want any page transferring it's data to the document until the sheet verifies that all pages passed validation.

One solution I find quite easy to do is to handle the OK button in the sheet. In that handler, I confirm whether each page is valid, and if it is, let it handle its own data exchange/validation. If any page fails validation, then the property sheet does not get dismissed.

I'll try that since in my OnApplyNow(), the OnOk could have already occurred and removed the window whereas if the "Apply" button was pressed, I'm still responsible for calling the UpdateData() for the active page.

Thanks for the tip.

I have a question about CControlBarInfo MFC class. First of all there is no documentation about it in the MSDN. It's declared in "Afxpriv.h".
The class is used to save and restore the state of the control bars through serialization. I don't need any serialization, I only want to know the positions of the toolbars in my application.

I have a MDI MFC application. Just to make sure we speak about the same thing:
1. An MDI application runs in a top level MDI parent frame.
2. That frame has an embedded child window, a <b>MDI client</b> window.
3. The MDI client window can host any number of MDI child windows.

My problem is the <b>MDI client</b> window. That window shares the client area of the parent with the docked toolbars and the status bar. I want to make that window smaller to make room for one more non-MDI window to be hosted by the same parent. It's possible, I did it, but I can't get along with the sizing calculations because of the random way the toolbars can be docked. I need info about the positions of the docked toolbars. The CControlBarInfo class offers any info I need, except one. I don't know how to find out to which side of the window is a toolbat docked. I can't relay on the window coordinates because there may be multiple toolbars, so a toolbar, even if docked, may not be adjacent to any border.
(Example: I can find out if it's visible, if it's docked. But I only can find out if it's verical. I don't know if it's docked to the right side or the left of the window).

Here is the only thing I know about the CControlBarInfo class, the declararion from the afxpriv.h file:
<code>class CControlBarInfo
{
public:
// Implementation
CControlBarInfo();

// Attributes
UINT m_nBarID; // ID of this bar
BOOL m_bVisible; // visibility of this bar
BOOL m_bFloating; // whether floating or not
BOOL m_bHorz; // orientation of floating dockbar
BOOL m_bDockBar; // TRUE if a dockbar
CPoint m_pointPos; // topleft point of window

UINT m_nMRUWidth; // MRUWidth for Dynamic Toolbars
BOOL m_bDocking; // TRUE if this bar has a DockContext
UINT m_uMRUDockID; // most recent docked dockbar
CRect m_rectMRUDockPos; // most recent docked position
DWORD m_dwMRUFloatStyle; // most recent floating orientation
CPoint m_ptMRUFloatPos; // most recent floating position

CPtrArray m_arrBarID; // bar IDs for bars contained within this one
CControlBar* m_pBar; // bar which this refers to (transient)

void Serialize(CArchive& ar, CDockState* pDockState);
BOOL LoadState(LPCTSTR lpszProfileName, int nIndex, CDockState* pDockState);
BOOL SaveState(LPCTSTR lpszProfileName, int nIndex);
};</code>

Or else, is there another way to find out the client area of a window not used by the status bar or the docked toolbars ?

Hi guys,

i want to start internet explorer in fullscreen mode (F11).
how can i do that?

it is no problem to start internet explorer with shellexecute:

ShellExecute(NULL, NULL,"C:\\Program Files\\Internet Explorer\\iexplore.exe","www.codeproject.com",NULL, SW_SHOWMAXIMIZED);

Try using this as an argument

"-k www.codeproject.com"

Works fine.

Thanks

How did you delete it?

shift delete

Which means you bypassed the Recycle Bin, which means it can't be recovered normally.

Hello All
I have Visual Studio 2005 Professional Edition, and I am working in an MFC project and I want to export it as a template.

How can I overcome this? and why it is deemed?

Hi to all,

Do anyone know how to create DirectShow Filter in VC++ (6.0 or .Net)?
Or Is there any link/e-book guiding to create DirectShow Filter?

I tried to get more information throught google. But it was not sufficient.

Please help me.

Thanks in advance.

And what about CP article's search engine http://www.codeproject.com/info/search.aspx?artkw=DirectShow+Filter&sbo=kw[^]?

And what about SDKs, if you are writting directshow filters, u might have installed DirectXSDK or Platform SDK, the SDK documentation is a huge source of Documentation and samples of DSHOW filters. The complete source code of DShow Baseclasses is also available, what else u need
