Didn't really know where else to put this so....does anyone know where I could find information or a tutorial on setting up CVS in Windows?

WinCVS was pretty straightforward. A bit confusing at the beginning, and the documentation could be thicker... but after a few minutes, it was up and running.

If anyone knows how to integrate CVS with MSDEV... please let me know.

Is there any way to programmatically close an opened pop-up menu that was invoked with an API like TrackPopupMenu?

I assume you mean the caret, not the cursor, and you want to do so programmatically.

If so, the best way to do so is to sublcass the edit box which allows you to control the positioning of the caret. However, you should be aware that this is not a trivial undertaking as you need to be knowledgeable of text sizing issues. The caret itself can also be problamatic to deal with.

Actually, I need to correct myself.

I checked and the CEdit api does have a PosFromChar method

So you could do something like this...

myedit.SetCaretPos( myedit.PosFromChar( index ));

That was not there the last time I had to do the same thing.

You can do it using the SetCaretPos() method.

void CEdit::SetSel(DWORD dwSelection, BOOL bNoScroll = FALSE);
void CEdit::SetSel(int nStartChar, int nEndChar, BOOL bNoScroll = FALSE);

To set the cursor at the end of the text within the control...

// With associated member variable to the edit control and to the content
UpdateData();
m_EditControl.SetSel(m_EditContent.GetLength(), m_EditContent.GetLength());


// With associated member variable to the content
UpdateData();
((CEdit *) GetDlgItem(IDC_EDIT))->SetSel(m_EditContent.GetLength(), m_EditContent.GetLength());

If you want to use the first function you have to set the starting position in the low-order word and and the ending position in the high-order word...thus

// With associated member variable to the edit control and to the content
UpdateData();

// Set position
DWORD dwSelection = m_EditContent.GetLength();
dwSelection |= m_EditContent.GetLength() << 16;

m_EditControl.SetSel(dwSelection);


// With associated member variable to the content
UpdateData();

// Set position
DWORD dwSelection = m_EditContent.GetLength();
dwSelection |= m_EditContent.GetLength() << 16;

((CEdit *) GetDlgItem(IDC_EDIT))->SetSel(dwSelection);

LPSTARTUPINFOW is a pointer to a STARTUPINFOW;

You must creaet a STARTUPINFOW object not a LPSTARTUPINFOW object.

STARTUPINFOW si;

LPSTARTUPINFOW lpsi = &si; // this step for illustration only, not really needed.

ZeroMemory(lpsi, sizeof(STARTUPINFOW));

Information extraction from website

Hi, am the author of a movie collection organizer and I have noticed that there are other ones like it that have the capability to extract movie information from the IMDb and add it to dialog boxes in their program. I would like to add this functionality to mine as well but I have no idea where to start from. Does the data access depend on the layout of the site and how they store their data or there are different ways to do the same thing. If anyone is familiar with this site and some tricks on how to extract data from it please help me out on this. Thanks in advance.

Are you serious? How can the other companies be doing it themselves. Besides they offer free access/downloads to all their info for non-commercial use, which is what I am doing since I am offering it for free.

Since the information online is likely to change frequently.
Decide on a report format that your program would like and
then put the parsing code on your web site. Make your program
download the parsing code (probably a small dll, or (my
preference) a perl script.) each session (hey, you're online
anyhow right?) and use that to parse the fetched web pages.

All you are doing then is acting on behalf of the user
legitimately. I mean, what's the big difference between
grabbing html and presenting it one way (most browsers)
and grabbing html and presenting it another (your program's
format)? Your web site would never see the web pages-- your
app is just a variation of browser. I don't think there
would be any legal issues in this case, but then that's
just a reasonable opinion.

Re: Information extraction from website

So basically what you think is going on is that people who have done this just wrote a routing to search through the html code, parse it, extract the details and just present it. Would an HTML session through Wininet suffice?

Re: Information extraction from website

Scott H. Settlemier23-Dec-02 7:46

Scott H. Settlemier

23-Dec-02 7:46

Yeah. I think that route is more robust. You can try to arrange
a method between yourself and the web site owners, but if you do
that you put yourself at the mercy of their support for that
interface.

I prefer to use perl in these cases, cause it is very good at
just this kind of work. There are tons of freely available
modules to make parsing html a snap. You can either pass on
the data to your web site for parsing or hand down the parsing
code to your app. (I don't recommend that your web site ever
try to contact the source site directly 'cause that could get
blocked.)

HTML through WININET is perfect.

Thanks for the info, maybe you can help me out a little more. Am I correct in thinking that an HTTP session through WININET is basically getting the contents of the HTML file the same way as if you were to "View Source" from Internet Explorer? (Meaning in that format). You also mentioned that Perl is perfect for this kind of stuff. Where can I get some online tutorials on Perl? Thanks again.

Re: Information extraction from website

Scott H. Settlemier23-Dec-02 8:51

Scott H. Settlemier

23-Dec-02 8:51

Yes, exactly. You also get the headers which don't show up in the "view source" option of IE.

Check out Perl.com [^]for Perl documentation.

The information you will want may require redirection and loading other
pages. So make your parser conversational.. i.e. hand it the first page,
let it parse and request further pages, hand it those pages and so forth
until it says done.

linking problem

22-Dec-02 0:19

Hey I have a linking problem that i can't seem to get rid of. I have a base class say:

class Base {
public:
    void draw();
private:
    ....
};

Then I have a class from that..

class Something : public Base {
public:
    void draw();
private:
    ....
};

I then have a std::list<Base> which I add objects to of type Something. i then go through the list and call each draw method.

// objects is the std::list
std::list<Base>::iterator item;
for ( item = objects.begin(); item != objects.end(); item++) {
    Base obj = *item;
    obj.draw();
}

But I get this error
error LNK2019: unresolved external symbol "public: void __thiscall Base::draw(void)" (?draw@Base@@QAEXXZ) referenced in function "public: bool __thiscall Sence::update(void)" (?update@Sence@@QAE_NXZ)

The std::list and the iteration of the list is done in another class. Reading the MSDN description of the error I can not firgure out whats wrong. commenting out the obj.draw(); line fixing it.

Any ideas? thanks.

Luke.
