Are you sure that it's dialog based? That message usually only is seen for SDI or MDI apps.

Hi,
I think some where near your View creation fails.
Check for OnCreate,... return -1;
This happens when the document is created with no views.

yes -1 is returned .
but i dont understand that how no view is created...

Hi,
What I meant is check whether the code hits on "return -1;" like statement upon execution.
ie; Your View creation may not be successfull, You may debug/review the code, this is only a hint. May be, you have overrided your frame window OnCreateClient and its baseclass is not called, causing it to create no view.

Thanks for the help . . .
Actually a toolbar resource was removed, but still the code for creating the toolbar was there... which lead to the same error

I Created a list view and modified the style with LVS_EX_CHECKBOXES, and the checkbox is created, but there is no image where the checkbox should be, only a blank space.

Here's part of the code:

Please if anybody has any clue as to what might be happening let me know.
I aoplogize if the OO library that I'm using, which is my own, can be a bit confusing, but it's basically the same Win32.

Hello
I need to apply margins to CEditView text while printing through a page setup dialog. these should be visible in print preview also.
any help ?
Thanks

hi all
i have made a SDI application
please help me
when i right click on a menu item
it will not show the event handler on menu item
// I double click on IDR_MAINFRAME and i will show mwnues
i add a tool menu and a dependent item under this but when i right
click on it it will not show event handler

thanks

hi

Can you more explainn do you want when you right click it shows a contextmenu or you want to fire an event?

I'd hoped since CHtmlView was derived from CFormView that I could use dialog templates to put controls over the HTML. Isn't that *why* it was derived from CFormView?

But CHtmlView has no constructor with a template parameter as CFormView(templateID) does.

And here I'd got a CDhtmlDialog test program working so well, thinking it would be easy to port to an existing MDI CFormView program I need the technique in Cry | :((

I don't think I can pass a templateID to protected CFormView(templateID) in the base initialization
although CHtmlView can, because its *directly* derived from CFormView, unlike my class.

// What CHtmlView does
CHtmlView::CHtmlView()
: CFormView((LPCTSTR) NULL)
{
}

// And I can't after deriving from CHtmlView
// error C2614: 'CMfcieView' : illegal member initialization: 'CFormView' is not a base or member
CMfcieView::CMfcieView()
: CFormView(IDD_MYDIALOG)
{
}

Hi,
If you want your CDhtmlDialog to be used in any of your view you can make it a modeless dialog and make a client of View window.
I prefer CDhtmlDialog, since It has already loaded with event sinks, while if you want CHtmlView to get events from controls like button click you need to code a little.

Sounds promising, thanks for your response.

Do you know of any examples, or a code snippet?

Hi,
I used similar method in my project, I used modeless CDHtmlDialog there.
I think there are lots of article in codeproject for CDhtmlDialog, please search.
MSDN example DhtmlExplore will give you a good start, it demonstrates dynamic
content on html page.

I think I already understand the CDHtmlDialog techniques.

I'm trying to figure out what you meant by "and make a client of View window".

Something like this? (which hasn't worked for me yet Blush | :O

)

BOOL CChildFrame::OnCreateClient(LPCREATESTRUCT /*lpcs*/, CCreateContext* pContext)
{
CDummyDlg *pDummy = new CDummyDlg();
BOOL res = pDummy->Create(IDD_DIALOG1, NULL);
return res;
/*
return m_wndSplitter.Create(this,
2, 2, // TODO: adjust the number of rows, columns
CSize(10, 10), // TODO: adjust the minimum pane size
pContext);
*/
}

WhiteSky has posted a link to document, which uses CDhtmlDialog Code and made a CView based class. You may try this,

And if you want modeless dialog method, would I like to know want's the problem, Does it isn't compiled or run time problem.

pDummy->Create(IDD_DIALOG1, NULL);
you are passing "NULL", you need to pass "this", then only it becomes the client of CChildFrame.

Moreover, I expect you to create a client of view. since you are making client of frame window, the document has no View object, this will cause problem.

I'd seen that sample, but it's not using any dialog templates.

Like you, I think I'd prefer to use CDHtmlDialog, if I could figure out how to display the dialog in the view Smile | :)

Ok,
Its simple,
1) create a modeless dialog of CDhtmlDialog.
Create a dialog resource and add class derived from CDhtmlDialog.
To make it modeless implement a default contructor and implement a simple create function

BOOL CYourModelssDHTMLdlg::Create(CWnd* pParentWnd)
{
	return CDHtmlDialog::Create(IDD_DIALOG1/* dialog id*/, pParentWnd);
}

use create() function in your CView OnCreate() / equavalent.

 int CYourView::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
	if (CView::OnCreate(lpCreateStruct) == -1)
		return -1;
	m_yourModelssDHTMLdlg.Create(this);	
}

Note: set the dialog style to WS_CHILD, WS_VISIBLE, No BORDER , NO TITLEBAR use resource designer or on your code (precreateWindow()).

2) On your Views OnSize()

void CYourView::OnSize(UINT nType, int cx, int cy)
{
	CView::OnSize(nType, cx, cy);

	m_yourModelssDHTMLdlg.MoveWindow(0, 0, cx, cy);
}

You might have missed it so you thought its not working.

Try this, this requires a time of 5~10 minutes.

Note: remember dialog style, resize and the dialog might have ok and cancel button this will cause the dialog to exitin its default behaviour.

I didn't explored CDHtmlDialog::EnableModeless, try this when you get time
