I'm using the headers that comes with VC6(sp5). I have MSDN(Jan. 2002). Is the SDK in that CD? Thx.

If you have an MSDN subscription other than the Library, you should have a CD with the platform SDK. If you only have a library subscription you'll need to obtain the platform SDK from the MSDN site.

EDIT - load & save text.

I feel like I'm missing something - I just try to load a text file into an Multiline EDIT, modify it, and save it again as text file. (should match notepad's behavior of hard line breaks)

Issue: just taking the file size and loading does not work because of the \n <--> \r\n conversion. For saving, it seems to double the line breaks, so it's bad again.

All I came up was either reading line-by-line, or reading as binary and do the replacements on my own. Which sounds a bit awkward.

Any suggestions?
TIA

setting focus to an editbox on a modal dlg, when the dlg is spawned

ns10-Jul-02 3:13

10-Jul-02 3:13

1) I tried putting the following:

CNewDialog cDlgNoOk;

cDlgNoOk.m_edit1.SetFocus();

Got a debug assert when it ran.

2) Then I tried putting it in the constructor- still asserts:

CNewDialog::CNewDialog(CWnd* pParent /*=NULL*/)
: CDialog(CNewDialog::IDD, pParent)
{
//{{AFX_DATA_INIT(CNewDialog)
none = NULL; // NOTE: the ClassWizard will add member initialization here
//}}AFX_DATA_INIT

m_edit1.SetFocus();
}
3)Finally I put it in :
BOOL CNewDialog::OnInitDialog()
{
CDialog::OnInitDialog();

// TODO: Add extra initialization here
m_edit1.SetFocus();
return TRUE; // return TRUE unless you set the focus to a control
// EXCEPTION: OCX Property Pages should return FALSE
}
It ran without asserting but the editbox didnt get the focus.....

Any suggestion on how to set the focus?
Thanks,
ns

Getting the process listening on a specific TCP port

Hi all.

Since we have written our own web server, our setup has to detect if there is already a application listening on port 80, so we can notify the user about the conflict. How can I get this information?

try bind()ing to the port and if the call fails then something is already on that port. u can however set a socket option to reuse it

destroying one view from another view - beginner

ns10-Jul-02 2:38

10-Jul-02 2:38

I see hoew to get the oh-so useful document pointer a lot, but if I want to destroy view2 from view1, how do I do that? If I had launched a dialog from my view, then I'd have the name like:

CMyDialog cDlg;

etc

cDlg.DestroyWindow.

But I didnt spawn view2 from view1, so how to I get its name or pointer to call DestroyWindow on it?

Thanks,
ns

You still need to go via that magic document. The document keeps pointers to all its views, which you can get access to via CDocument::GetFirstViewPosition() and CDocument::GetNextView() (which uses MFC's less than intuitive POSITION based iteration method - look the two methods up in the MSDN Library for details).

You can either call those methods from one view (using the view's pointer to its document) to destroy the other view, or you can define a method in your document which you call from one view to close the other. I prefer the second method, because it means the views don't have to know too much about the views they coexist with.

I´d try this :

// Win32 API:
HICON hLargeIcon = LoadIcon ( hinstYourModuleInstance, 
                              MAKEINTRESOURCE(IDI_NEW_ICON) );
HICON hSmallIcon = (HICON) LoadImage ( hinstYourModuleInstance, 
                                       MAKEINTRESOURCE(IDI_NEW_ICON),
                                       IMAGE_ICON, 16, 16, LR_DEFAULTCOLOR );
 
  SendMessage ( hwndYourWindow, WM_SETICON, ICON_BIG, hLargeIcon );
  SendMessage ( hwndYourWindow, WM_SETICON, ICON_SMALL, hSmallIcon );

During the initialization of your app's main window, you can load an icon from your resources like so:

<br />
WNDCLASS  wc;<br />
	<br />
wc.lpfnWndProc		= (WNDPROC)MainWndProc; <br />
wc.lpszClassName	= _T("MyAppClass");<br />
...<br />
wc.hIcon		= LoadIcon( hInstance, IDI_APPICON );<br />
...<br />
<br />
// Register the main windows class settings.<br />
if ( ! RegisterClass( &wc ) )<br />
   return FALSE;<br />

Add a resouce file (*.rc) to your project. Insert an icon (the one you want to use). Compile your application. If you import more than one icon, the compiler will arrange the icon resource ID's in alphabetical order. The first icon will then be associated with the EXE.

updateAllViews() - quick question

ns10-Jul-02 2:15

10-Jul-02 2:15

Hello,

If I want all views to update, its UpdateAllViews(NULL);

All other views but the sender -- UpdateAllViews(this);

What do I do if I want to update only my current view and none of the others?

Thank you very much,
ns

Re: updateAllViews() not in class wizard??

ns10-Jul-02 2:26

10-Jul-02 2:26

I was expecting to see the function UpdateAllViews in the classwizard entries for my doc class. There are functions like: setPathName, setTitle, GetNextView etc but not UpdateAllViews. Since its a CDocument object I can look in the MSDN for members, but why doesnt the class wizard have a list of all member functions, not just some? Why are the ones that are there, there?

Thanks,
ns

Re: updateAllViews() - quick question

peterchen10-Jul-02 4:03

call OnUpdate directly
(UpdateAllViews just calls OnUpdate for all views 8except the sender (if given)))
