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

Best wishes,

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.

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.

Adding checkboxes to a list view, checkbox image missing

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.

CHtmlView with dialog templates?

HappyFunBall5-Jun-07 18:19

5-Jun-07 18:19

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.

HappyFunBall5-Jun-07 19:05

5-Jun-07 19:05

Sounds promising, thanks for your response.

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

Rajkumar R5-Jun-07 19:30

5-Jun-07 19:30

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.

Raj

HappyFunBall5-Jun-07 20:16

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.

Best Regards
Raj

HappyFunBall5-Jun-07 21:21

5-Jun-07 21:21

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 | :)
