hello all,
i try to disable scrollbar in HtmlView.
i know i must work with IDocHostUIHandler::GetHostInfo();
and put the flag DOCHOSTUIFLAG_SCROLL_NO.
but i don't understand how implement this 
you know how to do this?
PS : i work with VC7.

VC7 makes your life easy! You only need to implement the new invented function OnGetHostInfo(DOCHOSTUIINFO *pInfo ).
F.i:
HRESULT MyView::OnGetHostInfo(
DOCHOSTUIINFO *pInfo )
{
pInfo->cbSize = sizeof(DOCHOSTUIINFO);
pInfo->dwFlags = DOCHOSTUIFLAG_SCROLL_NO;
return S_OK;
}

THX for your answer!!
yes with vc7 it seems easy 
but what is the command in message map ?

No entry in the message map required - it's a virtual function

Thx again Schlaubi!!
it's works perfectly !
but i can't decide when i want to show scrollbar or not.
its a problem for me...

sorry i have another question
you knwo how get the scrollabr position (always for htmlview)?
i can set a position to scrollbars
IDispatch *pDisp = GetHtmlDocument();
IHTMLDocument2 *pDocument = NULL;
pDisp->QueryInterface( IID_IHTMLDocument2, ( void** )&pDocument );
IHTMLElement* pBody = NULL;
pDocument->get_body( &pBody );
IHTMLWindow2* pWindow = NULL;
pDocument->get_parentWindow( &pWindow );
pWindow->scroll( 250, 300 );
but i don't know how get the position

|
|
When possessing a pointer to the body element (and you already have one), you could try calling IHTMLElement's offsetTop function. It should return the body's offset from the top of the page, and I hope that's what you're looking for
|

I think it's not exactly what i need.
when i resize window i want to scroll exactly where it is before resizing.
that's why i need to know the position of scrollbars.
You think with offsetTop,offsetLeft... i can do this ?
|
|
|
|
|
there is no problem i find how to do.
i want to thank you Schlaubi for your help !!

Hi,
I'm having a problem getting my hooks to work. I can successfully hook Keyboard and System messages (WH_KEYBOARD and WH_SYSMSGFILTER) but can't seem to be able to prevent Ctrl+Alt+Delete or MSGF_NEXTWINDOW from doing what they normally do.
I'm trying to prevent users of my app from accessing windows (definately not what i'd want, i know, but clients are clients), and i've got a feeling that part of the problem is the differences between 95/98 and 2k/XP? any ideas?
Thanks in advance to anyone who can help,
Alex

You'll never be able to hook that keystroke using a system wide hook or any other technique...
In order to do that you must create a GINA.DLL that handles that keystroke as you want...
Hope this helps...

I've been told this before - do you mean MSGINA.DLL? My version of Win98 doesn't have this dll present, but apparently WinNT does. does this matter?
Have you got any idea where I can look to find out a few clues on how to do this?
Cheers for the response,
Alex

hi
It is possible to hook Ctrl+Alt+Del combination by replacing the definition to Msgina.DLL in the registry by your own dll that is handling all the keyboard messages and forwarding all allowed key combinations to the original msgina.dll.
The easiest way to prevent unauthorized process kills is to use the VC++ resource editor, open msgina.dll and by making all buttons in the task manager dialog box disabled except Cancel. This is not a very beautiful method, but it works...
i saw an article on CP last days..search for it..it was on hooking ctrl + alt + del.. type something..
hope this works..

If I were to go a step further and prevent the Task Manager from even being shown, would I be able to write my own GINA.DLL (instead of changing microsoft's and just disabling buttons), and if so how easy is this to do and where would I start to look to do it?
Thanks for the reply!

Win95 + 98 don't have a MSGINA.DLL. Hooking can be done by setting the screensaver state programatically. The call
SystemParametersInfo(SPI_SETSCREENSAVERRUNNING, TRUE, lpvoid, 0)
blocks the keys, and
SystemParametersInfo(SPI_SETSCREENSAVERRUNNING, FALSE, lpvoid, 0)
re-enables them.
For replacing MSGINA.DLL you should search the MSDN. There're some good examples and explanations.

Thanks for that. I'd figured out the screensaver bits but was unsure if that was the accepted way of doing it.
Basically it sounds like such a muck-about to do all this that i'm probably going to try and get my boss to persuade the clients that they don't realy want this feature after all. If there were one way for all versions of Windows, then perhaps it would work, but I would also need to disable the Windows Key, Alt+Tab, Alt+Esc and Ctrl+Tab to actually prevent anyone using the app from accessing the desktop. All in all I'd never implement something like this through choice
Thanks for the support though!

Hi,
I was seraching the codeproject site and came across your post. I am sorry that no one has seemed to reply to your post. I was wondering if you managed to change the look of any of your property sheet buttons? I am trying to do the same...I want to simply change the color of the OK and other buttons.
Thank you for any help you are able to give.

Hello everyone!
I've been searching for a tutorial about creating ActiveX controles on a website (no asp.. just html & javascript)
One of my friends said that i should use "COM", but i haven't found anything that worked.. I've seen one here with cookies in ASP, but when i'm not using ASP, it's kinda hard..
maybe someone has a small source for an ActiceX control that returns a string.. like
This is a test: (call function from ActiveX control)-> "Test string returned from an ActiveX control"
I hope someone can help me or direct me to a good tutorial..

I tried to open a PE file with a program called PEExplorer .. Opend the header & discoverd that all the items in the header is correct..
but i found something strange i igot "the address of entry point" field from the header but when i checked that address i found it's so different from the contents that the PEExplorer program shows...
i found that the "image base" field is added some times 2 the address of the entry point field...
for example the address of entry point is: 0000E67Ch
& the image base is: 01000000h
but when i run the disassembler view of the PEExplorer i find that the address of the entry point is 0100E67Ch & this address can't be located coz the file size is smaller than it & the contents that the disassembler show in this location 0100E67Ch i can find it in another different place in my file
plz does any one knows how is this operation handled & how can i reach 2 the real entry point of an exe file...
my email is
blacksun_damn@yahoo.com,
ashshab_beh@yahoo.com
thanx alot ppl

The base is the recommeded address that the module should load at in memory at runtime.
The entry point of the module cannot be 0000E67Ch when it is loaded, because anything under the 4MB is reserved for the system. That is why the base address is added to the entry point, or the system will pick a new base address offset if that one is already taken.
The point is still, that the entry point of your function will be 0000E67Ch Bytes from the beginning of the base offset address.
Good Luck

How do I get the MAC address of a host that's not in the ARP-cache?
I'm using GetIpNetTable() to search the ARP-cache.
It works okay as long as the entry hasn't timed out yet.
I looked through <iphlpapi.h> and saw SendARP(). Unfortunately my MSDN collection is too old to document this function  . Could it be used for an ARP-resolution?
I need this to port libnet to Win-XP (first with MingW then MSVC).
Ref. http://www.packetfactory.net/libnet.
Thanks.

I hate to reply to my own posts, but for anyone interested..
I found some more details on SendARP() and why it's
not very usable.
- Not supported on Win9x/ME/NT.
- Doesn't add the result to the global ARP-cache.
- Doesn't retransmit on timeout.
So I probably end up writing my on ARP resolver.
