No. The angle brackets are actually missing, instead of just not being displayed.

It is to hard to solve this problem. But here are few my suggestions:

_Install the lastest Platform SDK. I think that file schannel.h is in new Platform SDK.

_Move the included lines to cpp file where it's functions used to check again.

Because, I don't know wintrust...so I can not test

Is your _WIN32_WINNT defined? It should be 0x0400 at least.

listview items dont appear

Hello,

In my MFC application, I am having a problem with my listview's items. They don't show. It looks like they are there because when they load the scroll bars appear.

The following code is OnCreate() where I Initialize the listView:

int CTopRightView::OnCreate(LPCREATESTRUCT lpCreateStruct)<br />
{<br />
	if (CView::OnCreate(lpCreateStruct) == -1)<br />
		return -1;<br />
<br />
	SetWindowLong(GetListCtrl().m_hWnd, GWL_STYLE,<br />
				  WS_VISIBLE|WS_CHILD|LVS_LIST);<br />
<br />
	COLORREF c = PALETTERGB(200, 70, 130);<br />
	GetListCtrl().SetBkColor(c);<br />
<br />
	//creating image list for listview<br />
	smallImageList.Create(16,16,false,1,0);<br />
<br />
	//adding icon to image list<br />
	HICON hIcon = ::LoadIcon(AfxGetResourceHandle(), <br />
							MAKEINTRESOURCE(IDI_ICON3));<br />
	smallImageList.Add(hIcon);<br />
<br />
	GetListCtrl().SetImageList(&smallImageList, LVSIL_SMALL);<br />
<br />
	return 0;<br />
}

And this piece of code adds an item to the listview:

<br />
		LV_ITEM lvItem;<br />
		::memset(&lvItem, 0, sizeof(LV_ITEM));<br />
		lvItem.mask = LVIF_TEXT|LVIF_IMAGE|LVIF_STATE;<br />
		lvItem.state = 0;<br />
		lvItem.stateMask = 0;<br />
		lvItem.pszText = GetNTS(GetDocument()->fileName);<br />
		lvItem.iItem = GetDocument()->fileCount;<br />
		lvItem.iImage = 0;<br />
<br />
		GetListCtrl().InsertItem(&lvItem);

Anybody might know what I am doing wrong? D'Oh! | :doh:

There's a much simpler way to do this, and you only have to do it once:

BOOL CTopRightView::PreCreateWindow(CREATESTRUCT& cs) 
{
    cs.style |= LVS_LIST;	
    return CListView::PreCreateWindow(cs);
}

What does InsertItem() return?

Hi David,

InsertItem() returns a positive value if successful or -1 otherwise.

So is it returning -1 in this case, or is it returning a positive value yet the items still do not show up?

I want to show multiline text in my dialog.

I have some conditions.

. If the number of lines is three or less it should come the center of the dialog vertically.

. If it exceeds 3 lines, 3 lines should appear to the user and a vertical scrollbar should come to view the remaining lines by scrolling down.

Which control should I use for the best result?

The text will be unicode format.

Thanks for suggestions.

I have an idea to dynamically set the window pos to center.

If I have the line height then can calculate the window pos.
And also set the visible line count to 3.

If you are wanting to center the actual edit control within its parent, you'll need to use MoveWindow() or SetWindowPos(). If you are using MFC, check out the CWnd::CenterWindow() method.

This sounds like an owner drawn control to me, unless the richedit box has a property to centre the text.

You can use MFC CEdit::GetLineCount() or the Win32 Message EM_GETLINECOUNT to get the number of lines.

--> . If the number of lines is three or less it should come the center of the dialog vertically.

I can't understand your question properly. do you meant to say if the number of lines are 3 or less, you don't want any scrollbar?

It sounds like you need to use the ES_CENTER and ES_MULTILINE styles.

HTMLView Problem...help.

Hello there guys.

Using VC++/MFC, I successfully created a new html file, but when the application was launch, an empty window appeared. The html created didn't display on that window.

For more details:

Inside of the MyAppView.cpp ::OnInitialUpdate(), a function is called that will create a html file(for e.g. CreateHtml("./test.htm") )where "test.htm" is the htm file created. Then Displaying the html using Navigate("file://..../test.htm"); I'm wondering why the window is empty. I check the test.htm file created and it's not empty. I also tried Navigate2("file://...../menu.htm") and still empty window was display...

Also, I tried passing it to an existing URL like "http://www.codeproject.com" and there's no problem with it.

I'd like to ask if I miss something there?. Is there's a way that the created html file is the display on the window?

Thanks..

I have re-created another project that had similar functions. It worked correctly.

Please, try to open created HTML files by IE to check whether that files display well or not.

Contact me if you want to get a working sample project by email.
