How do I specify the Rect tangle for my new CViews?

I have tried this ...

<br />
void CMyView::OnDraw(CDC* pDC)<br />
{<br />
COragomy_IIDoc* pDoc = GetDocument();<br />
ASSERT_VALID(pDoc);<br />
<br />
CRect rect = new CRect( 0, 0, 320, 200 );<br />
pDoc->m_clientRect = rect;<br />

... but it doesn't work.

Actually the code looks like this ...

<br />
void CMyView::OnDraw(CDC* pDC)<br />
{<br />
COragomy_IIDoc* pDoc = GetDocument();<br />
ASSERT_VALID(pDoc);<br />
<br />
CRect rect = new CRect( 0, 0, 320, 200 );<br />
pDoc->m_clientRect = rect;<br />
<br />

Try to see what exact error you've got. I used ShellExecute and it worked fine wherever the file is located

Creating HTML out of a formatted text message

Hello,

I am trying to create an email application in which users send HTML emails to one another. I am debating at present how to create the GUI for when a user composes the email. The problem is that I have to convert the email when it is sent, into HTML.

I first thought of CRichEditView, but that can't convert a formatted message into HTML. I looked at CHTMLView, but I think that all this does is provide a read-only browsing service with the Web Browser control.

Is there any way I can use CHTMLView to convert a text message into HTML? Or does anyone know of a library/DLL which can parse formatted text into HTML?

I would be very grateful for guidance here.

Thanks,
Trimtrom

Formatted text can easily be converted into HTML depending
on exactly what you want. For example,

CString convertToHTML(CString s)
{
return CString("<PRE>") + s + "</PRE>";
}

will do it. However, that doesn't allow the browser to reformat
line breaks. to do that simply search your string for any
blank lines (use the Find function in CString) and replace them
with "<p>".

Oh, and one other thing, you might have to hack grough the
string replacing special characters with their equivelents
in HTML. Specifically "<" with < ">" with > and " with
" (?? not sure of the exact spelling of this.)

Note that you don't need to put all the <HTML>, <HEAD> or
<BODY> tags as they are all optional. Though theoretically,
but not in practice, you are supposed to start all HTML with
the following tag:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

(assuming you are using English.)

If you need more complex formatting, you need to pull together
some sort of GUI to manipulate the text (i.e., have a bold button
insert <b></b>) If that is the case you need to look at
CHTMLEditCtrl.

Thanks for the reply.

I am using Visual C++ 6.0, and I have had a look all over the Help, and I can't find anything on CHTMLEditCtrl. Did this come in with version 7.0?? It sounds like something I would want.

I think basically I am looking for some control to turn text into HTML the same way the RichEditCtrl writes RTF files.

Any comments appreciated,

ATL/WTL Windows and fonts

[edit]N/m, DEFAULT_GUI_FONT works, although SYSTEM_FONT doesn't for some reason. [/edit]

I'm baffled.

I have a scenario like this:
I have a splitter window. One pane contains a window, written by me, which itself hosts two windows - one list control and one window written by me. It's in this last window my problems occur.

In the WM_PAINT handler I do the usual CPaintDC dc(*this) and then I get on with the actual drawing. I want to draw some text (using DrawText) using the default gui font. So i HFONT hOldFont = dc.SelectObject((HFONT)GetStockObject(DEFAULT_GUI_FONT)). But guess what? It's not the default gui font (Tahoma)! It's that damn fixed font. I also tried with SYSTEM_FONT to no avail. I did try OEM_FIXED_FONT which gave me Courier which seems ok according to the MSDN docs. GetStockObject() does not return NULL. I'm stumped! Have I missed some initialization, window style, window class style, or something?

It seems as if I posted this in the wrong forum, but I think it's in the right forum. I think the error is related to windows in general, not the toolkit. Smile | :)

FindFirstFile problem

I get weird results from this code:

void CGDlg::OnButton1() 
{
	WIN32_FIND_DATA wfd;
	HANDLE hRes = FindFirstFile("C:\\Documents and Settings\\dator19\\Skrivbord\\MUMMEL\\*.txt", &wfd);
	BOOL bOk = (hRes != INVALID_HANDLE_VALUE);
	while(bOk)
	{
		bOk = FindNextFile(hRes, &wfd);
		m_ListBox1.AddString(wfd.cFileName);
	}
}

I have 4 files (1.txt, 2.txt, 3.txt and 4.txt) in the directory but when I show the filnames in a listbox (m_ListBox1) the output is:

2.txt
3.txt
4.txt
4.txt

Hmm... what is wrong!
It should be:

1.txt
2.txt
3.txt
4.txt

FindFirstFile actually gives you a file - you need to add that to your list, too.

Try reversing the code in the while block

while(bOk)
{
	m_ListBox1.AddString(wfd.cFileName);	
	bOk = FindNextFile(hRes, &wfd);
}

May I ask one more question: If I change to *.* instead of *.txt it adds .. and ... into the listbox. What's that? Unsure | :~

current and parent folders.

you should add this check:

if ((findFileData.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)==FILE_ATTRIBUTE_DIRECTORY)
{
skip it
}
