I'd love to know where, I'd love to do a course that gives homework this in depth. But it's obviously been typed in from some sort of assignment description.

help with downloading from a login/pass web using php (repost)

help with downloading from a login/pass web using php Anonymous 12:48 17 Mar '02

hi, i would like to do something like that:

the website targeted use php to login with a username and a password.

and then, some menu is shown, (all using .php or .php3 extension for viewing pages.)

the fact is, if i do not log with my user/password within internet explorer, i can't even retrieve files i want using internet explorer.

but, even after logging in, and when i am able to download any file ending with .php3?someparam=somevalue&another=anothervalue etc...
when i use a offlinebrowser application to save all pages i want, the external application finally download a page which says i'm not logged on. although i can still download that page opening an internet explorer windows... (and setting the offline browser 'spider' to identify itself as IE doesn't solve the problem.)

so i have figured out that i need something, which will log in using a specified username/password, and then, will download all files linked from a single url. (and that need to work with either .php or .php3?x=1&pass=2 files...)

how can i do that?

Quick newbie question

I have a OnEraseBkgnd() function to change the background colour of my MDI app's frame window to a nice blue colour rather than boring grey... but every permutation of my attempts to do so don't work..

Can somebody please tell me the correct code for changing the background? I have this so far, but does not work:

BOOL CMainFrame::OnEraseBkgnd(CDC* pDC)
{
// Paint it a nice colour.
CBrush backBrush(0x00755121);
// Save old brush.
CBrush* pOldBrush = pDC->SelectObject(&backBrush);
CRect rcRect;
pDC->GetClipBox(&rcRect); // Erase the area needed.
pDC->PatBlt(rcRect.left, rcRect.top, rcRect.Width(), rcRect.Height(), PATCOPY);
pDC->SelectObject(pOldBrush);

return TRUE;
}

Thanks

I believe the problem is that you need to do this elsewhere to get the background of an MDI app. I forget exactly where, but my recollection is an article on this was posted recently.

Your code is correct for painting over a background. However the reason that it does not appear is because your MDI frame window, contains an MDI client window. This is where you will need to handle the erase background message.

You will have to sub class that window in order to handle that message. The MDI frame provides a variable m_hWndMDIClient that represents that handle of that window.

I've Windows XP, VC + SP5

I've installed (windowsxp.x86.fre.rtm.symbols.exe) but when I debug my application still they are not found:

[...]
Loaded 'C:\WINDOWS\system32\ole32.dll', no matching symbolic information found.
[...]

But "C:\WINDOWS\SYMBOLS\DLL\ole32.pdb" exists, it's been installed by the exe above.

I heard about a problem with 'pdb' files and about some changes to do in the registry under DevStudio but I don't remember more Frown | :(

Any help?

Thanks in advance.

Chances are you have applied a OS patch the XP and the OLE32.PDB doesn't match the DLL anymore.

Scrolling

31-Mar-02 9:21

Hi,

I was wondering how you would do a proper scrolling in a CScrollView
when you perform search and find and highlighting for characters? I mean there are ways to force the vertical scrollbar to move up and down, but how
do you make sure that it moves up and down only when it's necessary
(only when the item is outside of the current screen)?

CRect rcClient;

GetClientRect(&rcClient);

TEXTMETRICS tm;
CDC* pDC = CDC::FromHandle(::GetDC(this->m_hWnd));
pDC->GetTextMetrics(&tm);

int nLineHeight = tm.tmHeight (I think) + tm.tmAscent; (i think)

The above code would work on constant font size, but you would have to figure something else out if you have graphics and such or font's of different sizes.

Basically once you have individual line height and client area figured out, you would need to determine which line the word (found) was located.

int iLine = Search("Test");  //psuedo function

Now that you have the line index:

int nSpace = iLine * nLineHeight;

nSpace is the number of pixels all the lines up to the current indexed line consume.

By having this value and having you current viewing area(client rect) you could subtract client area by line height(s) and determine if the text is out of the viewing area and requires scrolling.

if(nSpace >= rcClient.bottom) //Requires scrolling
{
  //...Calculate required scrolling distance
  //...Set scrollbar(s) to calculated offset
}
else
  AfxMessageBox("Don't scroll...Text is within current area");

I'm missing a few thing i'm sure, but from the above you should get the gist of things and be able to take it one step further.

Cheers! Smile | :)

This stuff is easy to do and the only solution is to roll your own. I mean, if a common class exists to do a time trial, doesn't that mean by figuring out how to break it, someone can in one stroke crack every program that uses it ?

Edit box balloon tips in WinXP

This is pissing me off big time. I have an edit box in a dialog and want to show a balloon tip as soon as the dialog is open:

BOOL Welcome_OnInitDialog(HWND hDlg, HWND hWndFocus, LPARAM lParam)
{
	// Display the music folder (as saved in the registry)
	SetDlgItemText(hDlg, IDC_MUSIC_FOLDER, g_musicFolder);
	
	WCHAR szTitle[] = L"Music Folder";
	WCHAR szText[] = L"Enter the path to your music folder here, or click browse..";
	EDITBALLOONTIP ebt;
	ebt.cbStruct = sizeof(ebt);
	ebt.pszTitle = szTitle;
	ebt.pszText = szText;
	ebt.ttiIcon = TTI_INFO;
	Edit_ShowBalloonTip(GetDlgItem(hDlg, IDC_MUSIC_FOLDER), &ebt);

	return TRUE;
}

It is not working. Yet, when the user clicks the OK button. My WM_COMMAND hander has no problem displaying balloon tip:

void Welcome_OnCommand(HWND hDlg, int nId, HWND hWndCtrl, UINT uCodeNotify)
{
	HWND hMusicFolder = GetDlgItem(hDlg, IDC_MUSIC_FOLDER);

	if (nId == IDOK)
	{
		g_musicFolder.GetFromHWnd(hMusicFolder);
		DWORD dwFileAttributes = GetFileAttributes(g_musicFolder);
		if (dwFileAttributes == 0xffffffff || dwFileAttributes &
			FILE_ATTRIBUTE_DIRECTORY != FILE_ATTRIBUTE_DIRECTORY)
		{
			// Select the text in the text box.
			SendMessage(hMusicFolder, EM_SETSEL, 0, -1);
			// Display a balloon tip.
			WCHAR szTitle[] = L"Invalid folder name";
			WCHAR szText[] = L"Please confirm that this is the path to your music folder.";
			EDITBALLOONTIP ebt;
			ebt.cbStruct = sizeof(ebt);
			ebt.pszTitle = szTitle;
			ebt.pszText = szText;
			ebt.ttiIcon = TTI_WARNING;
			Edit_ShowBalloonTip(hMusicFolder, &ebt);
			
			return;
		}
.
.
.
}

What's going on? Any fixes?

Thanks

The dialog may not have finished initializing until OnInitDialog(). Try setting up the balloon tip within a handler for a fake command (I use IDC_INIT_GUI). Post the command (using PostMessage (WM_COMMAND, IDC_INIT_GUI)) from within OnInitDialog() to ensure that the handler will be executed after the dialog has initialized itself.
